Description
Technical field
The present invention relates to a kind of valve, be specifically related to a kind of water check valve being applied to scrubber.
Background technology
At present, being applied to the water check valve of scrubber is a kind of to be provided with the cleaning mixture of pressure by washing pump and push open and use spool
The spool that spring is pushed down, makes spraying cleaning solution go out, and after washing pump quits work, the valve core spring within water check valve is by spool bullet
Returning, closed by pipeline, the cleaning mixture in whole pipeline will not reflux, and when being again turned on scrubber's work, can will wash immediately
Wash liquid injection to forward and backward windshield.Water check valve is that the elastic force of the valve core spring internal by it pushes down spool, is not working
Time (no pressure) be to close, when in scrubber without cleaning mixture or user by cleaning mixture with when only needing again to add cleaning mixture,
So cannot discharge because of the normally closed of water check valve from the pump chamber of washing pump to the air connecting this section of channel interior of water check valve, if
There is air inside pump chamber, washing pump can be caused to dally, it is impossible to the ability of conveying cleaning mixture is provided, need manually by internal for pump chamber empty
After gas emptying, overall washing system can normally work, and reduces work efficiency.Generally, the spool of water check valve is by there being pressure
After liquid is pushed open, there is pressure fluid to flow through the spool of water check valve simultaneously, also can bring reverse thrust to spool, when pressure continues
Rise, retroaction also may proceed to increase, when the fluid pressure of spool both ends of the surface is equal, then liquid because of valve core spring elastic force without
Method pushes spool open, causes overall washing system do not spray water or spray water the most smooth.Therefore, this water check valve all can only be public in the restriction of design
Claim to work under pressure limit, thus greatly reduce the versatility of water check valve.
Summary of the invention
It is an object of the invention to overcome above-mentioned deficiency, and provide a kind of general water check valve of automatic vent type, it is intended to
It is automatically drained out circuit air, it can in addition contain improve its versatility.
The present invention is to realize by following technical solution: the general water check valve of automatic vent type, including valve seat, valve body, valve
Core, valve gap, be provided with interior breach on the inwall of described valve gap and in the end of its import, described valve body includes the outer valve being connected
Body and inner valve body, one end of this outer valve connects with valve gap, its other end connects with valve seat, on described inner valve body and leaning on
The interior indentation, there of nearly valve gap is equipped with valve block and valve block spring；Described inner valve body is provided with air-vent, at described inner valve body and valve
There is between sheet the gap communicated with this air-vent.
Equipped with spool bracing frame between described valve seat, outer valve and spool, the outer wall of described spool bracing frame is provided with
Brace rod and and between described valve seat, outer valve formed fluid passage.
After using present configuration, after scrubber's work stops, it is possible not only to prevent cleaning mixture from refluxing, the most all right
The pump chamber of washing pump to the air connecting this general this section of channel interior of water check valve is passed sequentially through valve gap import, valve gap, valve body
Valve pocket, gap, air-vent discharge emptying, open scrubber and but cannot carry asking of cleaning mixture after stopping to fill it up with cleaning mixture completely
Topic.Solve because the counteracting force of spool can not be pushed open the problem of spool by liquid, regardless of the pressure of scrubber simultaneously
Size issue, can be suitably used for the scrubber in any vehicle, and versatility is widely.
Accompanying drawing explanation
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the mounting structure schematic diagram of the general water check valve of automatic vent type of the present invention.
Fig. 2 is the axonometric chart of the spool bracing frame in Fig. 1.
Detailed description of the invention
Understand with reference to Fig. 1, Fig. 2, the general water check valve of automatic vent type of the present invention, including valve seat 2, valve body, spool 10 (and valve
Core spring 3), valve gap 7, be provided with interior breach 20 on the inwall of described valve gap 7 and in the end of its import, described valve body includes
Be connected outer valve 5 (in outside) and inner valve body 6 (in inside), one end of this outer valve 5 connects with valve gap 7, its other end and
Valve seat 2 connects, equipped with valve block 8 and valve block spring 9 on described inner valve body 6 and in the interior indentation, there near valve gap 7；Described
Inner valve body 6 is provided with air-vent 15 (this air-vent 15 is communicated with ambient atmosphere) by outer valve 5, at described inner valve body 6 and valve
There is between sheet 8 gap 14 communicated with this air-vent 15.Prop up equipped with spool between described valve seat 2, outer valve 5 and spool 10
Support 4, the outer wall of described spool bracing frame 4 be provided with brace rod 13 and and form liquid between described valve seat 2, outer valve 5 and lead to
Road 16 (see Fig. 2).
Wherein, the inside (i.e. the outside of inner valve body 6) of outer valve 5 has valve body valve pocket 17 and as degassing function, liquid
The cavity entered；The inside of valve seat 2 has the cavity that valve seat valve pocket 18 flows out as liquid, and with on spool bracing frame 4 outer wall
Fluid passage 16 communicate；The outlet of valve seat 2 can be connected with the nozzle on forward and backward windshield even by dead ring and pipeline
Logical, the pump chamber that the import of valve gap 7 is connected with the washing pump providing pressure by pipeline connects.
Operation principle of the present invention is as shown in drawings: this general check-valves (liquid no pressure), valve in the non-operational state
Core 10 is owing to being moved right by the elastic force of valve core spring 3, logical by be connected with valve body valve pocket and valve seat valve pocket on valve body, valve seat
Road is closed, and the liquid of valve seat valve pocket cannot be back in valve body valve pocket.Promote to the right valve block by the elastic force of valve block spring 9 simultaneously
The interior breach defined position of 8 to valve gap 7, makes the gap 14 on valve body valve pocket 17, inner valve body, air-vent 15 and the import of valve gap 7
The atmosphere extraneous with outer valve.When washing pump works, if having air in the pump chamber of washing pump and pipeline, washing pump is empty
Then the liquid of pressure cannot be provided with, and being equivalent to non-operational state, then the air in washing pump pump chamber and pipeline can pass through
Valve gap import, valve gap, valve body valve pocket, gap, air-vent are discharged, and a denier air emptying, liquid initially enters in washing pump pump chamber
Liquid is made to form pressure.Liquid enters valve gap 7 by valve gap import again and promotes valve block 8 to the left, makes valve body valve pocket, gap with saturating
The channel enclosed (valve block spring is compressed simultaneously) of pore connection, the liquid in valve body valve pocket continues push spool open and compress spool
Spring 3, liquid flows in valve seat valve pocket 18, then flows out from the outlet of valve seat 2.Described spool bracing frame 4 is its middle tool
Have on the cylindrical container of opening, its outer wall and there is a plurality of brace rod cincture, the two ends of this brace rod respectively with valve seat, outer valve
One end of coupling, valve core spring and spool is fixed in the cylindrical container being placed in spool bracing frame opening.
When liquid enters the fluid passage on valve seat valve pocket, spool bracing frame outer wall, spool only can be supported by its pressure
The outer wall of frame works, without working the spool in spool bracing frame, it is to avoid liquid to the counteracting force of spool and
Water check valve is caused to close the problem that cannot carry liquid.
