Describe purge cock assembly according to the embodiment of the invention in detail below with reference to accompanying drawing.
Shown in Fig. 1-4, the purge cock assembly according to the embodiment of the invention comprises: plug screw seat 10, closing means and suction bits plug screw 30.
Specifically, plug screw seat 10 comprises body section 101 and the construction section 102 that is positioned at above the body section 101.Be formed with in the body section 101 along about the first passage 1010 of (i.e. above-below direction as shown in Fig. 1 or Fig. 2) direction extension.Be formed with the internal thread (not shown) on the inwall of first passage 1010.Be formed with the second channel 1020 that extends and be communicated with first passage 1010 along the vertical direction in the construction section 102.Be formed with the top (i.e. construction section as shown in Fig. 1 or Fig. 2 make progress an end) of contiguous construction section 102 and first through hole 1021 that is communicated with second channel 1020 on the sidewall of construction section 102.Be formed with the bottom (i.e. the downward end of construction section as shown in Fig. 1 or Fig. 2) of contiguous construction section 102 and second through hole 1022 that is communicated with second channel 1020 on the sidewall of construction section 102.Be understandable that first through hole 1021 can be for a plurality of and evenly distribute along the outer circumferential face of construction section 102.Second through hole 1022 also can be a plurality of and evenly distributes along the outer circumferential face of construction section 102.
Described closing means is installed in the second channel 1020.Wherein, described closing means comprises spring 201 and spheroid 202.First end of spring 201 (i.e. an end that makes progress as Fig. 1 or spring 201 shown in Figure 2) against the top of second channel 1020 and second end of spring 201 (namely as the downward end of Fig. 1 or spring shown in Figure 2 201) link to each other with spheroid 202.Spring 201 and spheroid 202 also can be integrally formed, with the quantity of minimizing parts, thereby are convenient to install.
Inhaling bits plug screw 30 removably is located in the first passage 1010.Wherein, inhale bits plug screw 30 and comprise plug screw body 301 and the permanent magnetism cylinder 302 that links to each other with plug screw body 301.Be formed with the outside thread suitable with described internal thread on the outer wall of plug screw body 301.Plug screw body 301 and permanent magnetism cylinder 302 also can be integrally formed, with the quantity of further minimizing parts, are convenient to more install.Permanent magnetism cylinder 302 can be the rigidity material such as the permanent magnetism iron prop.
Wherein, as shown in Figure 1, when inhaling bits plug screw 30 and be installed in first passage 1010 in, permanent magnetism cylinder 302 against spheroid 202 to compress spring 201.At this moment, can between plug screw seat 10 and suction bits plug screw 30, add a pad 40, to form better sealing effect.As shown in Figure 2, when inhaling bits plug screw 30 disengagement first passages 1010, spring 201 promotes spheroids 202 sealing first passages 1010.
That is to say, purge cock assembly according to an embodiment of the invention is installed on the oil sump, first through hole 1021, second channel 1020, first passage 1010 and second through hole 1022 can form the loop.Be that the interior machine oil of oil sump can flow into second channel 1020 and first passages 1010 through first through hole 1021, inhaling bits plug screw 30 can adsorb the iron blood that contains in the machine oil by permanent magnetism cylinder 302, machine oil flows out from second through hole 1022 then, reenters oil sump.Through behind the certain hour, can make and inhale bits plug screw 30 and throw off first passages 1010, at this moment, spheroid 202 seals first passage 1010 under the effect of spring 201 restoring forces, makes oil sump still be in the state of sealing, as shown in Figure 2.And after inhaling bits plug screw 30 disengagement first passages 1010, then can clear up the iron filings that are adsorbed on the permanent magnetism cylinder 302.After cleaning out, inhale bits plug screw 30 and can be reinstalled in the first passage 1010.Thus, can under the very little situation of lubricating oil leakage amount, can regularly or clear up the interior iron filings of oil sump quantitatively.
According to one embodiment of present invention, shown in Fig. 1-2, described purge cock assembly comprises that also the cross section is the spring support 203 of T shape.Spring support 203 is located in second channel 1020 between the top and spring 201 of second channel 1020.Advantageously, the supporting leg of spring support 203 is plugged in the spring 201.Thus, can play a guide function with the working stability of assurance spring 201 to spring 201, and then after inhaling bits plug screw 30 disengagement first passages 1010, spring 201 promotes spheroid 202 better with sealing first passage 1010.
According to some embodiments of the present invention, can be formed with screw thread on the outer surface of the construction section 102 of plug screw seat 10.Purge cock assembly according to the embodiment of the invention is installed on the oil sump comparatively easily, and when needs more during change engine oil, then described purge cock assembly can disassemble comparatively easily from oil sump.Advantageously, form the flange 1011 that stretches out and be close to second through hole 1022 on the outer circumferential face of the body section 101 of plug screw seat 10.Thus, can obtain the better seal effect.
Purge cock assembly according to the embodiment of the invention, can under the situation of oil change not, check oil iron filings and with the iron filings sucking-off in the oil sump at the end, adopt this kind structure can reduce iron filings to the wearing and tearing of the movement parts of motor, and prolong the oil exchange cycle, have excellent economy and the feature of environmental protection.And, be installed on the oil sump according to the purge cock assembly of the embodiment of the invention is dismountable, when the oil sump inner engine oil need be changed, the dismounting of purge cock assembly is got final product down, convenient and practical.
In the description of this specification, concrete feature, structure, material or characteristics that the description of reference term " embodiment ", " some embodiments ", " example ", " concrete example " or " some examples " etc. means in conjunction with this embodiment or example description are contained at least one embodiment of the present invention or the example.In this manual, the schematic statement to above-mentioned term not necessarily refers to identical embodiment or example.And concrete feature, structure, material or the characteristics of description can be with the suitable manner combination in any one or more embodiments or example.
Although illustrated and described embodiments of the invention, those having ordinary skill in the art will appreciate that: can carry out multiple variation, modification, replacement and modification to these embodiments under the situation that does not break away from principle of the present invention and aim, scope of the present invention is limited by claim and equivalent thereof.
