Description

Distributor and discharge hose connector with built-in check valve {Distributor and discharge hose connector}

The present invention relates to a connection between a distributor and a discharge hose when a fluid provided from an inlet pipe is to be subdivided to be discharged through a discharge hose through a distributor. More specifically, The check valve is provided in the connection body so that the discharge hose can be easily connected to the dispenser and the fluid discharged from the check valve can be prevented from flowing backward Distributor and discharge hose.

Generally, a distributor is a device for discharging a fluid with pressure in various directions or with a capacity or a branch. The distributor is composed of one inlet and an optional outlet and a plurality of distribution outlets.

Thereby connecting the inlet to the fluid supply line and connecting the outlet to a discharge hose, such as a tube tube, which allows the fluid to be subdivided as a result of selective opening of the discharge hose, The fluid can be used in various forms from one fluid supply line.

At this time, the discharge hose normally prevents the fluid discharged through the discharge hose from flowing backward by the check valve by connecting a check valve between the distributor and the discharge hose, If a pressure drop occurs relative to the discharge pressure or if the pressure acting on the discharge hose rises above the supply pressure of the fluid, the fluid in the discharge hose may flow back toward the dispenser. To prevent this, It is common to combine valves.

At this time, the check valve is normally constituted by a spring-loaded opening / closing port, and the opening / closing port performs the opening and closing operation of the flow path in accordance with the moving direction of the fluid inside the check valve, so that the fluid discharged from the distributor does not flow back from the discharge hose I can not.

The connection configuration of such a dispenser and discharge hose check valve is typically such that when fluid is supplied to the interior of the dispenser 200 with pressure through a supply line 210 connected to one side of the dispenser 200 as shown in Figure 1 The distributor 200 distributes a small amount of fluid through the plurality of distribution outlets 201 and 201 '. At this time, since the discharge hoses 220 and 220 'are connected to the distribution outlets 201 and 201', subdivision discharge of the fluid is performed through the discharge hoses 220 and 220 ' The check valves 230 and 230 'are positioned between the dispensing outlets 201 and 201' and the discharge hoses 220 and 220 'to prevent the check valves 230 and 230' The connection between the check valves 230 and 230 'and the discharge hoses 220 and 220' is performed through the hose connection ports 240 and 240 'separately provided.

However, since the connection structure between the distributor and the discharge hose requires separate use of the check valve and the connection hole, it is not only complicated but also disadvantageous from a cost point of view. Even if a minute gap occurs due to the nature of the fluid, , There is a risk that the risk of leakage increases proportionally when a large number of parts are used.

In addition, the conventional hose connector is configured such that when a discharge hose made of synthetic resin or silicone is pressed into the hose connector by pressurization, the hose connector is watertightly fixed by friction or interference of the built-in rubber ring etc. There is a problem that leakage or leakage occurs when a gap is created due to aging or hardening of the rubber ring or malfunction, so that it is troublesome to finely and precisely finish and join the joint parts of each other.

For this reason, in order to propose a simple coupling method for the discharge hose, a tube-tube connection valve having a check valve has been proposed as disclosed in Korean Patent Application No. 0056579 of 2000, and the tube- The check valve is built in the connection valve so that the fluid can be prevented from flowing backward.

The tube pipe connecting valve includes an O-ring, a cap member, and a collector in a body member. When the tube pipe is forcibly inserted from one side of the body member, the tube pipe connection valve is made to fix the tube pipe by the O-ring and the cap member. It is designed to prevent reverse flow of fluid due to check valve function at the same time as pipe connection.

However, the above-mentioned tube-tube connecting valve has a more improved form than the conventional tube-tube connecting part, but there is a fear of leakage and leakage, and the fixing force of the tube tube is not strong. Or when a strong water pressure is suddenly applied, the tube tube is frequently disconnected from the connection valve.

Particularly, since the tube-tube connecting valve is used for connecting tube-shaped tubes separated from each other or applying a check valve function to the tube-tube itself, the distributor and the discharge tube (corresponding to the tube tube in the above description) .

Accordingly, there is an urgent need to develop an interconnecting member that can be connected to the dispensing outlet of the distributor more easily, while preventing reverse flow of the fluid discharged through the discharge hose.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide a dispenser having a dispensing outlet and a discharge hose, Check valve is used to connect the dispensing outlet and the discharge hose more easily and quickly, and at the same time, the watertight and airtight connection of the discharge hose is made, and a check valve The present invention has been made to solve the above-mentioned problems occurring in the prior art.

According to an aspect of the present invention, there is provided a connector comprising a connection body having a threaded portion formed on one outer surface thereof, a tube insertion groove, an exhaust flow passage, a valve flow groove, A groove, a ring-fitting groove, and a cap fixing groove are sequentially formed,

Wherein the pipe insertion groove is formed by inserting and fixing a perforated filter plate and a guide pipe in order and inserting an opening / closing port elastically locked in a spring in the valve flow groove to open / close the discharge flow passage, Wherein a locking ring for supporting the spring is inserted and a ring-shaped groove made of a soft resilient material is inserted into the ring-fitting groove, and the cap fixing groove is formed with a recessed ring body Can be achieved by coupling and fixing them.

The present invention is based on the idea that, in order to connect discharge hoses to a plurality of distribution outlets formed in the distributor, the check valve and the connection port are sequentially connected, but the connection between the distribution outlet and the discharge hose And the hose connection structure between the connection hose and the discharge hose is formed in a powerful and efficient shape so that the hose can be relieved from leakage or leakage of the fluid, It is possible to easily and safely separate the discharge hose without pulling the discharge hose by an excessive force even when it is intended to separate it, so that the separation and recombination can be performed very easily.

As shown in the drawing, the connector according to the present invention uses a connection body 10 manufactured by processing a metal material. A threaded portion 11 is formed on an outer surface of one side of the connection body 10, 120 and the hose connection means are connected to each other by the multi-stepped grooves formed in the inside of the connection body 10 .

That is, the connection body 10 is formed with a tube insertion groove 12 from one side where the screw portion 11 is formed and a discharge passage 13 having a relatively reduced inner diameter from the inner end of the tube insertion groove 12 is formed A valve flow groove 14 having an expanded inner diameter is formed at the end of the discharge flow passage 13 and a ring fixing groove 15 having an expanded inner diameter again from the end of the valve flow groove 14, (16) and the cap fixing grooves (17) of the expanded inner diameter are formed gradually and gradually with an expanded inner diameter.

When the perforated filter plate 20 is inserted into the tube insertion groove 12, holes of a small size are continuously and repeatedly formed in the perforated filter plate 20, and when foreign substances are contained in the fluid So that it can be filtered by the perforated filter plate (20). In addition, the guide pipe 30, which is separately provided in the state of inserting the perforated filter plate 20, is fixed to the perforated filter plate 20 by being forcedly inserted into the tube insertion groove 12, And one end of the guide tube 30 is protruded from the end of the connecting body 10 so that the guide tube 30 is inserted and fastened to the dispensing outlets 121 and 121 ' The guiding tube 30 can be guided and inserted into the outlet of the dispensing outlet 121 or 121 'so that the discharged fluid naturally flows through the inside of the guide tube 30 So that they can go out.

In addition, a discharge oil tool 13 'having a' + 'shape in cross section can be inserted into the discharge passage 13, and the discharge oil tool 13' Can be prevented from rotating in the form of a screw in the discharge passage (13) and can be prevented from being discharged, so that it is possible to suppress the rotation and flow to the object and means responsible for the check valve function .

An opening / closing port 40 made of a soft resilient material for opening and closing the discharge flow path 13 is inserted into the valve flow groove 14 and a spring 41 is inserted into one side of the opening / The opening / closing port 40 maintains a state in which it is elastically locked by a spring and is in a state of being in close contact with an end of the discharge passage 13. [

The other end of the spring 41 is seated by a retaining ring 50 inserted and fixed into the ring retaining groove 15 by a strong press-fit. The retaining ring 50 has a spring 41 and an opening / As shown in FIG.

The inner circumference of the cylindrical milling ring 60 is designed to be smaller than the inner diameter of the stationary ring 50 which is electrically connected to the ring-fitting groove 16, and a cylindrical milling ring 60 made of soft resilient material is inserted into the ring- The inner diameter of the discharge hose 110 is designed to be smaller than the outer diameter of the discharge hose 110 to be inserted. When the discharge hose 110 is inserted into the inner mill 60, mutual interference will occur. However, The discharge hose 110 inserted through the base mill 60 is completely inserted up to the inside of the stationary ring 50 and is inserted into the stationary ring 50, It can not be inserted any more because of interference with the inner end of the arm.

In addition, the finishing ring body 100, which is provided separately from the cap fixing groove 17, may be coupled and fixed in a state where the base ring 60 is inserted. Inside the finishing ring body 100, 70, the spring presser 80 and the presser 90 are engaged with each other.

That is, after the spring presser 80 is first inserted from the one side of the finishing ring body 100 and then the cementing tool 70 is fixed by interference fit, The spring pusher 80 has a circular shape and the wire is bent into a zigzag shape and has a central inclined shape. In addition, the cogwheel tool 70 has a shape of an inclined extension hole, and the spring presser 80 maintains the state where the edge is pressed and fixed by the cogwheel tool 70, So that it is inserted into the tool 70.

The pushing member 90 is inserted and fixed from the other side of the dead ring body 100. The pushing member 90 is provided at one side thereof with a protruding stopper 91 for interfering with one side of the spring pushing member 80 So that the end of the protruding stopper 91 is interfered with the spring presser 80 and the side of the protruding stopper 91 is coupled to the inside of the finish ring body 100 in the form of an undercut, (90) has a mating state from the finishing ring body (100).

At this time, a hermetic sealing part 14 'which is triangular in cross section is protruded from the end of the discharge flow path 13, that is, the inner side surface of the valve flow groove 14, and the hermetic sealing part 14' As the opening / closing port 40 is closely contacted, the airtightness due to the contact of the line and the surface is maintained rather than the airtight condition due to the contact between the surface and the surface.

5, when the discharge hose 110 is inserted inward from the direction of the pushing tool 90, which is one side of the connecting body 10, the outer surface of the discharge hose 110 and the spring presser 80 are inserted, The spring urging member 80 has an inclined shape so that the interior of the spring urging member 80 is expanded due to the insertion force of the discharge hose 110, And the end of the discharge hose 110 is connected to the inner side of the stationary ring 50. The end of the discharge hose 110 is connected to the inside of the stationary ring 50, When it reaches the end, the insertion is completed and the coupling is completed.

At this time, the spring presser 80 is in a state of continuously pushing the discharge hose 110, and the base mill 60 maintains a state in which it is completely in contact with the outer surface of the discharge hose 110.

In addition, when the discharge hose 110 is pulled by applying an artificial force in the separating direction, the spring presser 80 provides strong interference resistance against the separating direction of the discharge hose 110 due to the inclined shape, The hose 110 is in a state in which the hose 110 can not be separated from the connecting body 10 by an artificial force and the fluid supplied from the discharge passage 13 in the inflow and outflow direction by the base mill 60 is discharged to the discharge hose 110 and the inner portion of the base milling ring 60. As shown in FIG.

6, when the discharge hose 110 is separated from the connection body 10 as needed, the pushing member 90 (see FIG. 6), which is exposed and protruded to one side of the connection body 10, When the pushing member 90 is pushed in the direction of the connecting body 10, the end of the pushing-in member 91 of the pushing member 90 is interfered with the spring pushing member 80, (80) is forcibly expanded.

When the spring presser 80 is extended by the pressing of the pushing tool 90 and extended to the inclined surface 71 of the crawler tool 70, the spring presser 80 is completely separated from the discharge hose 110 And when the discharge hose 110 is pulled with an artificial force in such a state, the contact with the milling ring 60 is overcome and it can be separated from the connection body 10 by retracting.

Therefore, the connection of the discharge hose 110 to the connection body 10 can be performed in a rigid and excellent hermetic state only by inserting the discharge hose 110 into the connection body 10, When the discharge hose 110 is to be separated from the connection body 10, the discharge hose 110 can be easily separated from the connection body 10 by pulling the discharge hose 110 in a state in which the presser 90 is pressed. So that it is possible to maintain a good airtight condition with respect to the discharge hose 110 and at the same time to perform simple separation and coupling.

7, the fluid introduced through the guide pipe 30 passes through the perforated filter plate 20 and is discharged through the discharge flow path 13 and the discharge fluid The valve 40 is moved along the tool 13 'and pushes the opening / closing port 40 due to the pressure of the moving fluid. The opening / closing port 40 compresses the spring 41 and moves backward, And can be discharged to the outside through the inside of the discharge hose 110 through the inside of the groove 14.

In this state, when the pressure of the inner fluid of the discharge hose 110 is higher than the pressure of the supply fluid, reverse flow of the fluid will occur. Due to this backflow pressure, the opening / closing port 40 blocks the discharge flow passage 13, . At this time, since the opening / closing port 40 is compressively pressed against the contact portion by the airtightly adhered portion 14 'having a triangular shape in cross section, the stronger close state is maintained and the backflow can be effectively blocked . Then, when normal discharge of the fluid occurs in the backflow prevention state, the opening / closing port 40 compresses the spring 41 again due to the discharge pressure to open the discharge flow path 13, thereby smoothly performing the function of the check valve .

8, the connection port of the present invention can be easily coupled to the distribution outlets 121 and 121 'of the distributor 120 using the screw portion 11 of the connection body 10, The discharge hose 110 can be hermetically sealed simply by lightly pushing the discharge hose 110 into the lower end of the discharge hose 110. Therefore, the discharge hose 110 can be easily installed and used.

In order to more effectively perform the air-tightness operation, the air-conditioner 60 is formed of a soft resilient material so as to be kept in an effective hermetic state as it is in close contact with the outer surface of the discharge hose 110, More airtight action can be obtained by forming a plurality of circularly shaped airtight ribs 61 and 61 'repeatedly formed on the inner surface of the base mill 60.

That is, when the discharge hose 110 is inserted into the inside of the base milling ring 60, the airtight ribs 61 and 61 'are kept in close contact with the insertion hose 110 due to interference with the discharge hose 110 , So that the plurality of airtight ribs 61 and 61 'perform a multi-stage airtight action while acting as airtight objects. The airtight ribs 61 and 61 'inclined in the inserting direction may also serve to suppress the reverse separation of the discharge hose 110 so that the discharge hose 110 may be maintained in a more firmly coupled state .

As described above, the connection port between the distributor and the discharge hose of the present invention can be effectively used when it is desired to discharge a small amount of liquid, gas or the like of high pressure into various places through a distributor due to its easy use and excellent airtightness.
