Below with reference to the accompanying drawings the purge cock assembly according to the embodiment of the present invention is described in detail.
As Figure 1-4, according to the purge cock assembly of the embodiment of the present invention, comprising: plug screw seat 10, closing means, and inhale bits plug screw 30.
Specifically, plug screw seat 10 comprises body section 101 and the construction section 102 be positioned at above body section 101.The first passage 1010 that vertically (namely above-below direction) as illustrated in fig. 1 or fig. 2 direction extends is formed in body section 101.The inwall of first passage 1010 is formed with internal thread (not shown).Be formed in construction section 102 and extend along the vertical direction and the second channel 1020 be communicated with first passage 1010.The sidewall of construction section 102 is formed with the top (namely construction section one end upwards) as illustrated in fig. 1 or fig. 2 of contiguous construction section 102 and the first through hole 1021 be communicated with second channel 1020.The sidewall of construction section 102 is formed with the bottom (one end that namely construction section is as illustrated in fig. 1 or fig. 2 downward) of contiguous construction section 102 and the second through hole 1022 be communicated with second channel 1020.Be understandable that, the first through hole 1021 can be multiple and outer circumferential face along construction section 102 is uniformly distributed.Second through hole 1022 also can be multiple and along construction section 102 outer circumferential face and is uniformly distributed.
Described closing means is arranged in second channel 1020.Wherein, described closing means comprises spring 201 and spheroid 202.The first end of spring 201 (namely spring 201 one end upwards) as shown in Figure 1 or 2 against the top of second channel 1020 and the second end of spring 201 (one end that namely spring 201 is as shown in Figure 1 or 2 downward) be connected with spheroid 202.Spring 201 and spheroid 202 also can be integrally formed, and to reduce the quantity of parts, thus are convenient to install.
Inhale bits plug screw 30 to be removably located in first passage 1010.Wherein, the permanent magnetism cylinder 302 that bits plug screw 30 comprises plug screw body 301 and is connected with plug screw body 301 is inhaled.The outer wall of plug screw body 301 is formed with the outside thread suitable with described internal thread.Plug screw body 301 and permanent magnetism cylinder 302 also can be integrally formed, and to reduce the quantity of parts further, are more convenient to install.Permanent magnetism cylinder 302 can be the rigid of such as permanent magnetism iron prop.
Wherein, as shown in Figure 1, when inhale bits plug screw 30 be arranged in first passage 1010 time, permanent magnetism cylinder 302 against spheroid 202 with Compress Spring 201.Now, a pad 40 can be added, to form better sealing effect between plug screw seat 10 and suction bits plug screw 30.As shown in Figure 2, when inhaling bits plug screw 30 and throwing off first passage 1010, spring 201 promotes spheroid 202 and closes first passage 1010.
That is, be installed on oil sump by purge cock assembly according to an embodiment of the invention, the first through hole 1021, second channel 1020, first passage 1010 and the second through hole 1022 can form loop.Namely the machine oil in oil sump can flow into second channel 1020 and first passage 1010 through the first through hole 1021, inhale bits plug screw 30 iron blood contained in machine oil to be adsorbed by permanent magnetism cylinder 302, then machine oil flows out from the second through hole 1022, reenters oil sump.After certain hour, suction can be made to consider plug screw 30 to be worth doing and throw off first passage 1010, now, spheroid 202 closes first passage 1010 under the effect of spring 201 restoring force, makes oil sump still be in closed state, as shown in Figure 2.And after inhaling bits plug screw 30 throwing off first passage 1010, then can clear up the iron filings be adsorbed on permanent magnetism cylinder 302.After cleaning out, inhale bits plug screw 30 and can be reinstalled in first passage 1010.Thus, when engine oil leakage quantity is very little, the iron filings in oil sump can regularly or quantitatively be cleared up.
According to one embodiment of present invention, as shown in Figure 1-2, described purge cock assembly also comprises the spring support 203 that cross section is T-shaped.Spring support 203 is located between the top of second channel 1020 and spring 201 in second channel 1020.Advantageously, the supporting leg of spring support 203 is plugged in spring 201.Thus, a guide function can be played to ensure the working stability of spring 201 to spring 201, and then after suction bits plug screw 30 throws off first passage 1010, spring 201 promotes spheroid 202 better with closed first passage 1010.
According to some embodiments of the present invention, the outer surface of the construction section 102 of plug screw seat 10 can be formed with screw thread.Can make thus to be installed on oil sump comparatively easily according to the purge cock assembly of the embodiment of the present invention, and when machine oil changed by needs, then described purge cock assembly can disassemble from oil sump comparatively easily.Advantageously, the outer circumferential face of the body section 101 of plug screw seat 10 is formed and stretches out and the flange 1011 of contiguous second through hole 1022.Thus, good sealing effect can be obtained.
According to the purge cock assembly of the embodiment of the present invention, iron filings at the oil end can be checked and by the iron filings sucking-off in oil sump when not oil change, adopt this kind of structure can reduce the wearing and tearing of iron filings to the movement parts of motor, and extend the oil exchange cycle, there is good Economy and the feature of environmental protection.Further, be arranged on oil sump according to the purge cock assembly of the embodiment of the present invention is dismountable, when oil sump inner engine oil needs to change, the dismounting of purge cock assembly is lower, convenient and practical.
In the description of this specification, specific features, structure, material or feature that the description of reference term " embodiment ", " some embodiments ", " example ", " concrete example " or " some examples " etc. means to describe in conjunction with this embodiment or example are contained at least one embodiment of the present invention or example.In this manual, identical embodiment or example are not necessarily referred to the schematic representation of above-mentioned term.And the specific features of description, structure, material or feature can combine in an appropriate manner in any one or more embodiment or example.
Although illustrate and describe embodiments of the invention, those having ordinary skill in the art will appreciate that: can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present invention and aim, scope of the present invention is by claim and equivalents thereof.
