Description

Water treatment machine and control valve for water treatment machine

Technical Field

The present utility model relates to a water treatment machine, and more particularly, to a water treatment machine capable of performing multistage treatment on raw water (e.g., tap water) to obtain treated water having a desired water quality. The utility model further relates to a control valve for a water treatment machine.

Background

In modern industrial production, many industries require water of high cleanliness or low hardness. However, many water sources, whether surface or underground, have cleanliness and hardness that are not as high as industrial water. In order to obtain water of a desired quality, it is necessary to treat water (or raw water) from a water source. Raw water is treated by coarse filtration, which is to filter out larger particle contaminants to obtain coarse-filtered water, then further filtering the coarse-filtered water by using activated carbon and other materials to obtain cleaner purified water, and finally softening (or ultrafiltration or RO membrane filtration) the obtained purified water to obtain softened water (or purified water with extremely high purity). Finally, the raw water is subjected to multi-stage treatment (three-stage or more treatment) to obtain treated water having a desired water quality. For example, people sequentially filter and ultrafilter raw water by using a water filter device (the filter material is quartz sand, activated carbon or PP cotton filter material, etc.) and a water ultrafiltration device (the filter material is ultrafiltration membrane yarn generally), or sequentially filter, ultrafilter and RO membrane process raw water by using a water filter device, a water ultrafiltration device and an RO membrane water purifying device, or sequentially coarsely filter, filter and soften raw water by using a pre-filter, a water filter device and a water softener.

In addition, with the increasing enhancement of the living standard and the increasing importance of health, the quality requirements of people on living water are also higher. However, waterworks are relatively extensive in the treatment of water retrieved from the source, and are not adequate for removal of all impurities, e.g. particulate contaminants (floc gels, silt, even bacteria, etc.), and are increasingly difficult to meet. In addition, the aging of the tap water supply pipe network can bring new pollution to tap water. Therefore, in order to further purify tap water and improve the cleanliness thereof, various water treatment means are also required to treat tap water.

However, most of the existing water treatment systems or water treatment apparatuses capable of performing multistage treatment on raw water include a plurality of water treatment devices and a plurality of control valves for controlling water to flow inside the respective water treatment devices, respectively, because each water treatment device has a corresponding control valve, each control valve controls the water treatment function and the flushing function of the respective water treatment device, respectively, and thus the plurality of control valves are connected in series. The multiple control valves of the water treatment system lead to high manufacturing cost and large occupied space, and meanwhile, the multiple control valves cause higher failure rate of the whole water treatment system because the control valves are more complex devices. The utility model patent application number CN202022865712.3 discloses a water treatment system, which has three filtering tanks connected in series, controls the flow direction of water and performs three-stage treatment on the water through a single control valve, and solves the problem of excessive number of control valves of the water treatment system. However, the water treatment system disclosed in the patent is very simple in structure, and although it can perform multistage treatment on raw water by using three filter tanks connected in series, it cannot perform back flushing or forward flushing on the filter tanks separately and individually. The structure of the water treatment system disclosed in the patent means that when three filter tanks connected in series are subjected to forward flushing, sewage generated by forward flushing of a first filter tank flows into a second filter tank, sewage generated by forward flushing of the second filter tank flows into a third filter tank, and when three filter tanks connected in series are subjected to reverse flushing, sewage generated by reverse flushing of the third filter tank flows into the second filter tank, and sewage generated by reverse flushing of the second filter tank flows into the first filter tank. In other words, when three filter media tanks connected in series are forward-flushed, only the first filter media tank may be cleaned, while the second filter media tank and the third filter media tank may not be cleaned, but may be further contaminated, while when three filter media tanks connected in series are backward-flushed, only the third filter media tank may be cleaned, while the second filter media tank and the first filter media tank may not be cleaned, but may be further contaminated. In particular, the cleaning effect of forward flushing and backward flushing three filter material tanks connected in series of the water treatment system may be worse in consideration of the stepped reduction effect of the three filter material tanks connected in series on the raw water pressure. In other words, the existing water treatment machine has a certain inconvenience to the user due to the lack of functions. Finally, generally, the control valve of the water treatment machine adopts a traditional double-valve plate structure, and at least one flow guide blind hole is required to be arranged on the movable valve plate so as to change the flow direction of water. However, when the water flows in the blind flow guide holes, the flow direction is changed by 360 degrees, so that the water is subjected to larger resistance and the kinetic energy of the water is greatly lost, and the flow rate of the water is obviously reduced.

As shown in fig. 11A, 11B and 18A of the drawings, illustratively, when the plane valve 1 of the water treatment machine according to the embodiment of the present utility model is controlled to be at the water treatment working position, raw water from the plane valve 1 flows into the valve cavity 110 from the second fluid opening 1107 of the valve body 10 under the action of water pressure, flows into the first opening 1101 through the seventh passage 107 and the first passage 101, flows into the first water treatment device 51 from the first water inlet 511 of the first water treatment device 51, is treated (e.g., purified or softened) by the first water treatment material 515 under the action of water pressure, and the generated primary treatment water is collected by the first central tube 514 and flows out from the first water outlet 512 of the first water treatment device 51; under the action of water pressure, the primary treatment water further flows through the second opening 1102, the second passage 102, the eighth passage 108, the third passage 103, and the third opening 1103 of the plane valve 1 to the second water inlet 521 of the second water treatment device 52 and flows into the second water treatment device 52, then under the action of water pressure, is treated (e.g., purified or softened) by the second water treatment material 525, and then the generated secondary treatment water is collected by the second center pipe 524 and flows out from the second water outlet 522 of the second water treatment device 52, then under the action of water pressure, flows to the third water inlet 531 of the third water treatment device 53 and flows into the third water treatment device 53, under the action of water pressure, is treated (e.g., purified or softened) by the third water treatment material 535, and then the generated tertiary treatment water is collected by the third center pipe 534, and out of the third water outlet 532 of the third water treatment device 53 and towards the fifth opening 1105 of the planar valve 1, the fifth passage 105, the ninth passage 109, the sixth passage 106 and through the first fluid opening 1106.

As shown in FIG. 10C, FIG. 10D of the drawings, As shown in fig. 12 and 18B, the planar valve 1 of the water treatment machine according to the embodiment of the present utility model further has a first backwash operation position, and when the planar valve 1 is in the first backwash operation position, the seventh channel 107 of the planar valve 1 is communicated with the second channel 102 to form the first backwash flow channel 7101 respectively communicated with the second fluid opening 1107 and the second opening 1102, and the ninth channel 109 is respectively communicated with the tenth channel 1010 and the first channel 101 to form the second backwash flow channel 7102 respectively communicated with the drain opening 11010 and the first opening 1101. As shown in fig. 7A to 7I, 10C, 10D and 18B of the drawings, when the plane valve 1 is in the first backwash operation position, the eighth passage 108 of the plane valve 1 communicates with the fourth passage 104, the third passage 103 and the fifth passage 105 are blocked by the second fluid control surface 1220 of the valve plate 122, and the sixth passage 106 is blocked by the third fluid control surface 1223 of the valve plate 122, respectively. Thus, when the planar valve 1 is in the first backwash operation position, although the eighth passage 108 of the planar valve 1 is in communication with the fourth passage 104 and the eighth passage 108 is a blind via, the fourth passage 104 is blocked by the movable valve plate 122 and since the third passage 103 and the fifth passage 105 are blocked by the second fluid control surface 1220 of the movable valve plate 122, respectively, raw water can only flow from the second fluid opening 1107 of the planar valve 1 into the seventh passage 107 and further flow through the second passage 102, the second opening 1102, the first water outlet 512 to the first water treatment device 51 and into the first water treatment device 51, waste water generated by backflushing the first water treatment device 51 flows from the first water inlet 511 of the first water treatment device 51 to the first opening 1101 of the planar valve 1 and further flows under water pressure through the first passage 101 of the planar valve 1, the ninth passage 109, the tenth passage 1010, and the drain opening 11010 are discharged. In other words, although the eighth passage 108 communicates with the fourth passage 104, the water flow does not flow through the flow passages formed by them. Accordingly, when the planar valve 1 is in the first backwash operation position, the third passage 103 and the fifth passage 105 are blocked by the second fluid control surface 1220 of the movable valve plate 122, respectively, thereby preventing water flow through the third opening 1103 and the fifth opening 1105 of the planar valve 1, and the eighth passage 108 is a blind via-hole although the eighth passage 108 is in communication with the fourth passage 104, whereby water flow is prevented from flowing through the fourth opening 1104 of the planar valve 1, thereby preventing water flow in the second water treatment device 52 and the third water treatment device 53. In other words, although the eighth passage 108 communicates with the fourth passage 104, and the eighth passage 108 is a blind hole, the third passage 103, the third opening 1103, the second water treatment device 52, the third water treatment device 53, the fifth opening 1105 and the fifth passage 105 of the plane valve 1 are sequentially communicated and the second water treatment device 52 and the third water treatment device 53 are connected in series, since the movable valve plate 122 blocks the flow of raw water to the third passage 103, the fourth passage 104 and the fifth passage 105, thereby ensuring that only the first water treatment device 51 is backwashed.

It is noted that when the planar valve 1 is in the first back flushing operation position, the third channel 103, the fourth channel 104 (or the flow channel formed by the eighth channel 108 and the fourth channel 104) and the fifth channel 105 are all blocked by the movable valve plate 122, so that the third opening 1103, the fourth opening 1104 and the fifth opening 1105 are all blocked, and although the eighth channel 108 is communicated with the fourth channel 104, no water flow in the fourth opening 1104, that is, the second water treatment device 52 and the third water treatment device 53 are connected in series, and at the same time, the third opening 1103, the fourth opening 1104 and the fifth opening 1105 are all blocked by the movable valve plate 122, so that the second water treatment device 52 and the third water treatment device 53 are isolated from the water flow, so that only the first water treatment device 51 is guaranteed to be back flushed, thereby improving the strength of the water flow of the raw water back flushing the first water treatment device 51, and preventing the generated sewage from flowing to the second water treatment device 52 and/or the third water treatment device 53. Thus, the first water treatment device 51 of the water treatment machine of the present utility model is backwashed separately when the planar valve 1 is in the first backwash operating position.

As shown in fig. 12 and 18B of the drawings, illustratively, when the plane valve 1 of the water treatment machine according to the embodiment of the present utility model is controlled to be in the first backwash operation position, raw water from the plane valve 1 flows into the first water treatment device 51 from the first water outlet 512 of the first water treatment device 51 under the action of water pressure, then flows from the first central pipe 514 to the first water treatment material 515 and backflushes the first water treatment material 515 under the action of water pressure, and generated sewage flows out from the first water inlet 511 of the first water treatment device 51 and flows to the first opening 1101 of the plane valve 1 under the action of water pressure, and then flows to the sewage drain opening 11010 and is discharged through the second backwash flow passage 7102.

As shown in FIG. 10E, FIG. 10F of the drawings, As shown in fig. 13 and 18C, the planar valve 1 of the water treatment machine according to the embodiment of the present utility model further has a second backwash operation position, and when the planar valve 1 is in the second backwash operation position, the seventh passage 107 of the planar valve 1 is communicated with the fourth passage 104 to form the third backwash flow passage 7103 respectively communicated with the second fluid opening 1107 and the fourth opening 1104, and the ninth passage 109 is respectively communicated with the tenth passage 1010 and the third passage 103 to form the fourth backwash flow passage 7104 respectively communicated with the drain opening 11010 and the third opening 1103. As shown in fig. 7A to 7I, 10E, 10F and 18C of the drawings, when the plane valve 1 is in the second backwash operation position, the eighth passage 108 is respectively communicated with the first passage 101 and the fourth passage 104, the second passage 102 and the fifth passage 105 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, and the sixth passage 106 is blocked by the third fluid control surface 1223 of the movable valve plate 122. Although the eighth passage 108 is communicated with the first passage 101 and the fourth passage 104, respectively, since the eighth passage 108 is a blind through hole, and since the second passage 102 and the fifth passage 105 are blocked by the second fluid control surface 1220 of the movable valve plate 122, respectively, so that raw water can flow only from the second fluid opening 1107 of the plane valve 1 into the seventh passage 107, and further through the fourth passage 104, the fourth opening 1104, the second water outlet 522 of the second water treatment device 52 and into the second water treatment device 52, waste water generated by back flushing the second water treatment device 52 flows from the second water inlet 521 of the second water treatment device 52 to the third opening 1103 of the plane valve 1, and further through the third passage 103 of the plane valve 1 under the action of water pressure, the ninth passage 109, the tenth passage 1010, and the drain opening 11010 are discharged. In other words, although the eighth passage 108 of the plane valve 1 is respectively connected to the first passage 101 and the fourth passage 104, the water flow does not flow through the flow passage formed by the eighth passage 108 as the second passage 102 is blocked by the second fluid control surface 1220 of the movable valve plate 122 and the eighth passage 108 is a through blind hole. Thus, when the planar valve 1 is in the second backwash operation position, the second passage 102 and the fifth passage 105 of the planar valve 1 are blocked by the second fluid control surface 1220 of the movable valve plate 122, respectively, such that the flow of water in the second opening 1102 and the fifth opening 1105 of the first valve body 11 of the planar valve 1 is blocked, such that the flow of water from the first opening 1101 of the first valve body 11 of the planar valve 1 to the first water inlet 511 of the first water treatment device 51 is blocked, such that the flow of water from the fourth opening 1104 to the third water inlet 531 of the third water treatment device 53 is blocked, and such that the flow of water in the first water treatment device 51 and the third water treatment device 53 is blocked. Accordingly, when the plane valve 1 is in the second backwash operation position, the flow of water flows in the first water inlet 511 and the first water outlet 512 of the first water treatment device 51, the third water inlet 531 and the third water outlet 532 of the third water treatment device 53 are also blocked to ensure that only the second water treatment device 52 is backwashed to prevent generated sewage from flowing to the first water treatment device 51 and/or the third water treatment device 53 while increasing the strength of the water flow for backwash of the second water treatment device 52. Thus, the second water treatment device 52 of the water treatment machine of the present utility model is separately backwashed when the planar valve 1 is in the second backwash operating position. In addition, when the raw water backflushes the second water treatment device 52, the backflushing water flow from the fourth opening 1104 cannot flow to the third water inlet 531 of the third water treatment device 53, and the water flow from the first opening 1101 cannot flow to the first water inlet 511 of the first water treatment device 51, thereby ensuring the water flow strength of backflushing the second water treatment device 52 and avoiding pollution of the first water treatment device 51 and the third water treatment device 53 by the blowdown water flow generated after backflushing the second water treatment device 52.

It is noted that when the planar valve 1 is in the second backwash operation position, the second channel 102 and the fifth channel 105 are blocked by the movable valve plate 122, respectively, so that the second opening 1102 and the fifth opening 1105 are blocked, and even though the eighth channel 108 is communicated with the first channel 101 and the fourth channel 104, respectively, no water flows in the first opening 1101, the second opening 1102 and the fifth opening 1105, no water flows in the first water treatment device 51 and the third water treatment device 53, so that only the second water treatment device 52 is backwashed, and the generated sewage can be prevented from flowing to the first water treatment device 51 and/or the third water treatment device 53 while the strength of the backwash water flow of the raw water to the second water treatment device 52 is improved. Thus, the second water treatment device 52 of the water treatment machine of the present utility model is separately backwashed when the planar valve 1 is in the second backwash operating position.

As shown in fig. 13 and 18C of the drawings, illustratively, when the plane valve 1 of the water treatment machine according to the embodiment of the present utility model is controlled to be in the second backwash operation position, raw water from the plane valve 1 flows into the second water treatment device 52 from the second water outlet 522 of the second water treatment device 52 under the action of water pressure, then flows from the second center pipe 524 to the second water treatment material 525 and backflushes the second water treatment material 525 under the action of water pressure, and generated sewage flows out from the second water inlet 521 of the second water treatment device 52 and flows to the third opening 1103 of the first valve body 11 of the plane valve 1 under the action of water pressure, then flows to the sewage discharge opening 11010 and is discharged through the fourth backwash flow passage 7104.

As shown in FIG. 10G, FIG. 10H of the drawings, as shown in fig. 14 and 18D, the planar valve 1 of the water treatment machine according to the embodiment of the present utility model further has a third back flushing operation position, and when the planar valve 1 is in the third back flushing operation position, the seventh passage 107 of the planar valve 1 is communicated with the fifth passage 105 to form the fifth backwash flow channel 7105 respectively communicated with the second fluid opening 1107 and the fifth opening 1105, and the ninth passage 109 is respectively communicated with the tenth passage 1010 and the fourth passage 104 to form the sixth backwash flow channel 7106 respectively communicated with the drain opening 11010 and the fourth opening 1104. As shown in fig. 7A to 7I, 10G, 10H and 18D of the drawings, when the plane valve 1 is in the third back flushing operation position, the eighth passage 108 of the plane valve 1 communicates with the first passage 101, the second passage 102 and the third passage 103 are blocked by the second fluid control surface 1220 of the moving valve plate 122, and the sixth passage 106 is blocked by the third fluid control surface 1223 of the moving valve plate 122, respectively. Although the eighth passage 108 is communicated with the first passage 101, since the eighth passage 108 is a blind through hole and since the second passage 102 and the third passage 103 are blocked by the second fluid control surface 1220 of the movable valve plate 122, respectively, so that raw water can only flow from the second fluid opening 1107 of the plane valve 1 into the seventh passage 107 and further flow to the third water outlet 532 of the third water treatment device 53 and into the third water treatment device 53 through the fifth passage 105, the fifth opening 1105, the waste water generated by back flushing the third water treatment device 53 flows from the third water inlet 531 of the third water treatment device 53 to the fourth opening 1104 of the plane valve 1 and further flows under the action of water pressure through the fourth passage 104 of the plane valve 1, the ninth passage 109, the tenth passage 1010, and the drain opening 11010 are discharged. In other words, although the eighth passage 108 of the plane valve 1 communicates with the first passage 101, the eighth passage 108 is a blind through hole, so that the first passage 101 is blocked by the movable valve plate 122, and the second passage 102 and the third passage 103 are blocked by the second fluid control surface 1220 of the movable valve plate 122, respectively, so that the flow of water in the first opening 1101, the second opening 1102 and the third opening 1103 of the first valve body 11 of the plane valve 1 is blocked, and the flow of water from the third water inlet 531 of the third water treatment device 53 to the second water outlet 522 of the second water treatment device 52 is blocked. Thus, the flow of water in the first water treatment device 51 and the second water treatment device 52 is blocked. Accordingly, when the plane valve 1 is in the third back flushing operation position, the flow of the water flows in the first water inlet 511 and the first water outlet 512 of the first water treatment device 51, the second water inlet 521 and the second water outlet 522 of the second water treatment device 52 is also blocked to ensure that only the third water treatment device 53 is back flushed to prevent the generated sewage from flowing to the first water treatment device 51 and/or the second water treatment device 52 while increasing the intensity of the water flow back flushing the third water treatment device 53. Thus, the third water treatment device 53 of the water treatment machine of the present utility model is backwashed separately when the planar valve 1 is in the third backwashed operating position. In addition, when the raw water backflushes the third water treatment apparatus 53, the sewage flowing out of the third water inlet 531 of the third water treatment apparatus 53 and flowing to the fourth opening 1104 cannot flow to the second water outlet 522 of the second water treatment apparatus 52, thereby avoiding pollution of the second water treatment apparatus 52 by the sewage generated after backflushing the third water treatment apparatus 53.

It is noted that when the plane valve 1 is in the third back flushing operation position, the first channel 101 (or the flow channel formed by the eighth channel 108 communicating with the first channel 101), the second channel 102 and the third channel 103 are blocked by the movable valve plate 122, respectively, so that the first opening 1101, the second opening 1102 and the third opening 1103 are blocked, even if the eighth channel 108 communicates with the first channel 101, no water flow in the first opening 1101, the second opening 1102 and the third opening 1103, no water flow in the first water treatment device 51 is isolated from the water flow, no water flow in the second water treatment device 52 is ensured to be back flushed only by the third water treatment device 53, and generated sewage can be prevented from flowing to the first water treatment device 51 and/or the second water treatment device 52 while the strength of the water flow by back flushing the third water treatment device 53 is improved. Thus, the third water treatment device 53 of the water treatment machine of the present utility model is backwashed separately when the planar valve 1 is in the third backwashed operating position.

As shown in fig. 14 and 18D of the drawings, illustratively, when the plane valve 1 of the water treatment machine according to the embodiment of the present utility model is controlled to be in the third reverse flushing operation position, raw water from the plane valve 1 flows into the third water treatment device 53 from the third water outlet 532 of the third water treatment device 53 under the action of water pressure, then flows into the third water treatment material 535 and reversely flushes the third water treatment material 535 from the third central pipe 534 under the action of water pressure, and the generated sewage flows out from the third water inlet 531 of the third water treatment device 53 under the action of water pressure, flows into the fourth opening 1104 of the first valve body 11 of the plane valve 1, then flows into the sewage discharge opening 11010 and is discharged through the sixth backwash flow passage 7106.

As shown in FIG. 10I, FIG. 10J of the drawings, As shown in fig. 15 and 18E, the surface valve 1 of the water treatment machine according to the embodiment of the present utility model further has a first forward flushing operation position, when the surface valve 1 is in the first forward flushing operation position, the seventh passage 107 of the surface valve 1 communicates with the first passage 101 to form the first forward flushing flow passage 7201 communicating with the second fluid opening 1107 and the first opening 1101, respectively, and the ninth passage 109 communicates with the tenth passage 1010 and the second passage 102, respectively, to form the second forward flushing flow passage 7202 communicating with the drain opening 11010 and the second opening 1102, respectively. As shown in fig. 7A to 7I, 10I and 10J of the drawings, when the flat valve 1 is in the first forward flushing operation position, the eighth passage 108 of the flat valve 1 is communicated with the third passage 103, the fourth passage 104 and the fifth passage 105 are blocked by the second fluid control surface 1220 of the movable valve plate 122, and the sixth passage 106 is blocked by the third fluid control surface 1223 of the movable valve plate 122, respectively. As shown in fig. 10I, 10J and 18E of the drawings, when the plane valve 1 is in the first positive flushing operation position, although the eighth passage 108 of the plane valve 1 is in communication with the third passage 103, since the eighth passage 108 is a through blind hole, the third passage 103 is blocked by the moving valve plate 122, and the fourth passage 104 and the fifth passage 105 are blocked by the second fluid control surface 1220 of the moving valve plate 122, respectively, so that raw water can flow into the seventh passage 107 only from the second fluid opening 1107 of the plane valve 1, and further through the first passage 101, the first opening 1101 flows to the first water inlet 511 of the first water treatment device 51 and flows into the first water treatment device 51, and the waste water generated by forward flushing the first water treatment device 51 flows from the first water outlet 512 of the first water treatment device 51 to the second opening 1102 of the plane valve 1 and is further discharged through the second passage 102, the ninth passage 109, the tenth passage 1010 and the drain opening 11010 of the plane valve 1 by the water pressure. In other words, although the eighth passage 108 of the plane valve 1 communicates with the third passage 103, since the eighth passage 108 is a blind hole, the water flow does not flow through the flow passage formed by them. Accordingly, when the planar valve 1 is in the first forward flushing operation position, the third passage 103 is blocked by the movable valve plate 122, the fourth passage 104 and the fifth passage 105 are blocked by the second fluid control surface 1220 of the movable valve plate 122, respectively, thereby preventing water flow through the third, fourth and fifth openings 1103, 1104, 1105 of the planar valve 1, and thus water flow is prevented from flowing through the third, fourth and fifth openings 1103, 1104, 1105 of the planar valve 1, thereby preventing water flow in the second and third water treatment devices 52, 53. In other words, although the eighth passage 108 is in communication with the third passage 103, since the eighth passage 108 is a blind via and the fourth passage 104 and the fifth passage 105 are blocked by the second flow control surface 1220 of the movable valve plate 122, respectively, the movable valve plate 122 blocks the flow of raw water to the third passage 103, the fourth passage 104 and the fifth passage 105, thereby ensuring that only the first water treatment device 51 is positively flushed.

It is noted that when the plane valve 1 is in the first positive flushing operation position, the third channel 103 (or the flow channel formed by the communication between the eighth channel 108 and the third channel 103), the fourth channel 104 and the fifth channel 105 are blocked by the movable valve plate 122, respectively, so that the third opening 1103, the fourth opening 1104 and the fifth opening 1105 are blocked, even if the eighth channel 108 is in communication with the third channel 103, no water flows in the third opening 1103, the fourth opening 1104 and the fifth opening 1105, that is, the second water treatment device 52 and the third water treatment device 53 are isolated from the water flow, so that only the first water treatment device 51 is positively flushed, and the generated sewage can be prevented from flowing to the second water treatment device 52 and/or the third water treatment device 53 while the strength of the water flow of the first water treatment device 51 being positively flushed is improved. Thus, the first water treatment device 51 of the water treatment machine of the present utility model is solely positively flushed when the planar valve 1 is in the first positive flush operating position.

As shown in fig. 15 and 18E of the drawings, illustratively, when the plane valve 1 of the water treatment machine according to the embodiment of the present utility model is controlled to be in the first forward flushing operation position, raw water from the plane valve 1 flows into the first water treatment device 51 from the first water inlet 511 of the first water treatment device 51 under the action of water pressure, and then the first water treatment material 515 is positively flushed under the action of water pressure, and generated sewage is collected by the first central pipe 514 and flows out from the first water outlet 512 of the first water treatment device 51 and flows to the second opening 1102 of the plane valve 1 under the action of water pressure, and then flows to the sewage discharge opening 11010 and is discharged through the second forward flushing flow channel 7202.

As shown in FIG. 10K, FIG. 10L of the drawings, As shown in fig. 16 and 18F, the flat valve 1 of the water treatment machine according to the embodiment of the present utility model further has a second positive flushing operation position, when the flat valve 1 is in the second positive flushing operation position, the seventh passage 107 of the flat valve 1 communicates with the third passage 103 to form the third positive flushing passage 7203 communicating with the second fluid opening 1107 and the third opening 1103, respectively, and the ninth passage 109 communicates with the tenth passage 1010 and the fourth passage 104, respectively, to form the fourth positive flushing passage 7204 communicating with the drain opening 11010 and the fourth opening 1104, respectively. As shown in fig. 7A to 7I, 10K and 10L of the drawings, when the flat valve 1 is in the second positive flushing operation position, the eighth passage 108 of the flat valve 1 communicates with the fifth passage 105, the first passage 101 and the second passage 102 are blocked by the second fluid control surface 1220 of the movable valve plate 122, and the sixth passage 106 is blocked by the third fluid control surface 1223 of the movable valve plate 122, respectively. As shown in fig. 10K, 10L and 18F of the drawings, specifically, when the plane valve 1 is in the second positive flushing operation position, although the eighth passage 108 of the plane valve 1 is in communication with the fifth passage 105, the eighth passage 108 is a blind via hole, so that the fifth passage 105 is blocked by the movable valve plate 122, and the first passage 101 and the second passage 102 are blocked by the second fluid control surface 1220 of the movable valve plate 122, respectively, so that raw water can flow into the seventh passage 107 only from the second fluid opening 1107 of the plane valve 1, and further through the third passage 103, The third opening 1103 flows to the second water inlet 521 of the second water treatment device 52 and flows into the second water treatment device 52, and the waste water generated by forward flushing of the second water treatment device 52 flows from the second water outlet 522 of the second water treatment device 52 to the fourth opening 1104 of the plane valve 1 and is further discharged through the fourth passage 104, the ninth passage 109, the tenth passage 1010 and the drain opening 11010 of the plane valve 1 by the water pressure. In other words, although the eighth passage 108 communicates with the fifth passage 105, the water flow does not flow through the flow passage formed by them. Accordingly, when the planar valve 1 is in the second forward flushing position, the first, second and fifth passages 101, 102 and 105 are all blocked by the movable vane 122, thereby preventing water flow through the first opening 1101 of the planar valve 1, The second opening 1102 and the fifth opening 1105 prevent the flow of waste water from the second water treatment device 52 from flowing out of the second water outlet 522 of the second water treatment device 52 and then to the third water inlet 531 of the third water treatment device 53, and although the eighth passage 108 of the planar valve 1 is in communication with the fifth passage 105, the first passage 101 and the second passage 102 are blocked by the second fluid control surface of the movable valve plate 122, respectively, due to the blind hole being the eighth passage 108, the flow of water is prevented from flowing through the first opening 1101, the third passage 531 of the planar valve 1, the second opening 1102 and the fifth opening 1105, thereby preventing the flow of water in the first water treatment apparatus 51 and the third water treatment apparatus 53. In other words, although the eighth passage 108 of the plane valve 1 is in communication with the fifth passage 105, since the eighth passage 108 is a blind passage and the first passage 101 and the second passage 102 are blocked by the second flow control surface 1220 of the movable valve plate 122, respectively, the movable valve plate 122 blocks the flow of water to the first passage 101, the second passage 102 and the fifth passage 105, thereby ensuring that only the second water treatment device 52 is positively flushed.

It is noted that when the plane valve 1 is in the second positive flushing operation position, the first channel 101, the second channel 102 and the fifth channel 105 (or the flow channel formed by the eighth channel 108 and the fifth channel 105) are blocked by the movable valve plate 122, respectively, so that the first opening 1101, the second opening 1102 and the fifth opening 1105 are blocked, that is, the first water treatment device 51 is isolated from the water flow, and no water flow in the third water treatment device 53 exists, so as to ensure that only the second water treatment device 52 is positively flushed, thereby improving the strength of the water flow generated by the water which is positively flushing the second water treatment device 52 and preventing the generated sewage from flowing to the first water treatment device 51 and/or the third water treatment device 53. Thus, the second water treatment device 52 of the water treatment machine of the present utility model is solely positively flushed when the planar valve 1 is in the second positive flush operating position.

As shown in fig. 16 and 18F of the drawings, illustratively, when the plane valve 1 of the water treatment machine according to the embodiment of the present utility model is controlled to be in the second forward flushing operation position, raw water from the plane valve 1 flows into the second water treatment device 52 from the second water inlet 521 of the second water treatment device 52 under the action of water pressure, and then the second water treatment material 525 is flushed forward under the action of water pressure, and generated sewage is collected by the second central pipe 524 and flows out from the second water outlet 522 of the second water treatment device 52 and flows to the fourth opening 1104 of the plane valve 1 under the action of water pressure, and then flows to the sewage discharge opening 11010 and is discharged through the fourth forward flushing flow path 7204.

As shown in FIG. 10M, FIG. 10N of the drawings, As shown in fig. 17 and 18G, the flat valve 1 of the water treatment machine according to the embodiment of the present utility model further has a third positive flushing operation position, when the flat valve 1 is in the third positive flushing operation position, the seventh passage 107 of the flat valve 1 communicates with the fourth passage 104 to form the fifth positive flushing passage 7205 communicating with the second fluid opening 1107 and the fourth opening 1104, respectively, and the ninth passage 109 communicates with the tenth passage 1010 and the fifth passage 105, respectively, to form the sixth positive flushing passage 7206 communicating with the drain opening 11010 and the fifth opening 1105, respectively. As shown in fig. 7A to 7I, 10M and 10N of the drawings, when the flat valve 1 is in the third forward flushing operation position, the eighth passage 108 of the flat valve 1 is respectively communicated with the second passage 102 and the fifth passage 105, the first passage 101 and the third passage 103 are respectively blocked by the second fluid control surface 1220 of the movable valve plate 122, and the sixth passage 106 is blocked by the third fluid control surface 1223 of the movable valve plate 122. As shown in figure 10M of the drawings, As shown in fig. 10N and 18G, in particular, when the flat valve 1 is in the third forward flushing operation position, although the eighth passage 108 of the flat valve 1 is in communication with the second passage 102 and the fifth passage 105, respectively, since the first passage 101 and the third passage 103 are blocked by the second fluid control surface 1220 of the movable valve plate 122, respectively, the eighth passage 108 is a blind via-hole, so that both the first passage 101 and the third passage 103 are blocked by the movable valve plate 122, and no water flow occurs in the second passage 102, so that raw water can flow into the seventh passage 107 only from the second fluid opening 1107 of the flat valve 1, and further through the fourth passage 104, The fourth opening 1104 flows to the third water inlet 531 of the third water treatment device 53 and flows into the third water treatment device 53, and the waste water generated by forward flushing the third water treatment device 53 flows from the third water outlet 532 of the third water treatment device 53 to the fifth opening 1105 of the plane valve 1 and is further discharged through the fifth passage 105, the ninth passage 109, the tenth passage 1010 and the drain opening 11010 of the plane valve 1 by the water pressure. In other words, although the eighth passage 108 communicates with the second passage 102 and the fifth passage 105, respectively, water does not flow through the flow passages formed by them. Accordingly, when the planar valve 1 is in the third forward flushing operation position, both the first passage 101 and the third passage 103 are blocked by the movable valve plate 122, thereby preventing water flow through the first opening 1101 and the third opening 1103 of the planar valve 1, preventing water flow from the second opening 1102 of the first valve body portion 11 of the planar valve 1 to the first water outlet 512 of the first water treatment device 51, and preventing water flow from the fourth opening 1104 of the first valve body portion 11 of the planar valve 1 to the second water outlet 522 of the second water treatment device 52, thereby preventing water flow in the first water treatment device 51 and the second water treatment device 52. In other words, although the eighth passage 108 of the plane valve 1 communicates with the second passage 102 and the fifth passage 105, respectively, so that the first passage 101, the first opening 1101, the first water treatment device 51, the second opening 1102, the second passage 102, the eighth passage 108 and the fifth passage 105 of the plane valve 1 communicate sequentially, the first passage 101 and the third passage 103 are blocked by the second fluid control surface 1220 of the movable valve plate 122, respectively, so that the movable valve plate 122 blocks the flow of water to the first passage 101, the second passage 102 and the third passage 103, thereby ensuring that only the third water treatment device 53 is positively flushed.

It is noted that when the plane valve 1 is in the third forward flushing operation position, the first channel 101 and the third channel 103 are blocked by the movable valve plate 122, respectively, so that the first opening 1101 and the third opening 1103 are blocked, and even though the eighth channel 108 is communicated with the second channel 102 and the fifth channel 105, respectively, no water flows in the first opening 1101, the second opening 1102 and the third opening 1103, that is, no water flows in the first water treatment device 51 and the second water treatment device 52, so as to ensure that only the third water treatment device 53 is flushed forward, thereby preventing the generated sewage from flowing to the first water treatment device 51 and/or the second water treatment device 52 while improving the strength of the water flow for forward flushing the third water treatment device 53. Thus, the third water treatment device 53 of the water treatment machine of the present utility model is solely positively flushed when the planar valve 1 is in the third positive flush operating position.

As shown in fig. 17 and 18G of the drawings, illustratively, when the plane valve 1 of the water treatment machine according to the embodiment of the present utility model is controlled to be in the third forward flushing operation position, raw water from the plane valve 1 flows into the third water treatment device 53 from the third water inlet 531 of the third water treatment device 53 under the action of water pressure, and then the third water treatment material 535 is positively flushed under the action of water pressure, and generated sewage is collected by the third central pipe 534 and flows out from the third water outlet 532 of the third water treatment device 53 and flows to the fifth opening 1105 of the plane valve 1 under the action of water pressure, and then flows to the sewage discharge opening 11010 and is discharged through the sixth forward flushing flow path 7206.

It is noted that, the conventional planar valve adopts a valve core structure of a single movable valve plate and a single fixed valve plate, and the movable valve plate often needs a through blind hole to guide water flow to the water outlet. When water flows in the diversion blind hole, the flow direction is changed by 360 degrees, so that the water flow is subjected to larger resistance and the kinetic energy of the water flow is greatly lost, and the flow rate of the water flow is obviously reduced. The plane valve 1 of the water treatment machine adopts a three-valve structure, water flows upwards from the lower valve plate (the first fixed valve plate 121), the water outlet is arranged on the upper valve plate (the second fixed valve plate 123), the change of the water flow direction is small (approximate), the resistance of the water flow in the process of changing the water flow direction is also small, and the loss of the water flow is obviously reduced. Further, the existing planar valve having a single fixed valve plate can only have a channel for controlling the flow direction of water flow provided at the fixed valve plate, which results in a large diameter of the fixed valve plate of the planar valve and a large volume of the entire planar valve in order to ensure the flow rate of water. The larger the diameter of the planar valve, the more difficult it is to ensure the stability of the movable valve plate when it rotates. In order to ensure the stability of the whole planar valve, the sectional area of the planar valve is increased, the valve body needs to have a thicker wall thickness, and the thickness of the movable valve plate needs to be correspondingly increased, which not only causes the manufacturing cost of the planar valve to be increased, but also causes the whole planar valve to be more heavy and difficult to operate. The first channel 101, the second channel 102, the third channel 103, the fourth channel 104, the fifth channel 105, the sixth channel 106 and the tenth channel 1010 of the plane valve 1 of the water treatment machine according to the present utility model are respectively disposed at the first fixed valve block 121 and the second fixed valve block 123, thereby allowing the space occupied by each channel disposed at the fixed valve block to be enlarged and increasing the flow rate of water. In other words, the first channel 101, the second channel 102, the third channel 103, the fourth channel 104, the fifth channel 105, the sixth channel 106 and the tenth channel 1010 of the planar valve 1 of the water treatment machine according to the present utility model are respectively disposed on the first fixed valve plate 121 and the second fixed valve plate 123, so that the diameter (or the inner diameter of the valve cavity) of the fixed valve plate, the thickness of the movable valve plate and the wall thickness of the valve body of the planar valve can be significantly reduced, thereby reducing the manufacturing cost of the planar valve and making the entire planar valve structure lighter and easier to operate.

As shown in fig. 6C to 10N of the drawings, the fourth passage 104 of the plane valve 1 of the water treatment machine according to the embodiment of the utility model has a first communicating portion 1041 and a second communicating portion 1042, wherein the first communicating portion 1041 of the fourth passage 104 is communicated with the fourth opening 1104, and the second communicating portion 1042 of the fourth passage 104 is communicated with the fourth opening 1104. Preferably, the fourth channel 104 of the plane valve 1 further has a third communication portion 1043 extending between the first communication portion 1041 and the second communication portion 1042, the first communication portion 1041 of the fourth channel 104 communicates with the fourth opening 1104, the second communication portion 1042 of the fourth channel 104 communicates with the first communication portion 1041 through the third communication portion 1043, that is, the second communication portion 1042 of the fourth channel 104 communicates with the fourth opening 1104 through the third communication portion 1043 and the first communication portion 1041. Preferably, the first passage 101 of the plane valve 1 is provided outside the third communication portion 1043.
