Description
Technical field
The utility model relates to pressure retaining valve technical fields, especially automobile absorber high pressure pressure retaining valve.
Background technique
Pressure maintaining refers to pressure fixing, and pressure decline is kept to be no more than a certain standard whithin a period of time.Similarly, high pressure pressure maintaining
Valve is mainly used in automobile absorber, and effect is to guarantee that the high pressure gas in automobile absorber keeps stablizing, currently, with vapour
The update of vehicle product is increasingly severe, and traditional high pressure pressure retaining valve can not meet people's needs.Traditional high pressure is protected
Pressure valve has the disadvantage that the components in traditional high pressure pressure retaining valve are more, if one of components damage, maintenance
Higher cost, maintenance difficulty is big, and secondly there are higher security risks.
Summary of the invention
In view of the deficiencies of the prior art, the utility model provides that a kind of structure is simple, and the stable automobile absorber of pressure maintaining is high
Press pressure retaining valve.
The technical solution of the utility model are as follows: automobile absorber high pressure pressure retaining valve, it is characterised in that: it includes pressure retaining valve master
Body, O-ring, pipeline, spool, annular groove, compressed spring, spring cup, gasket and hickey, the pressure maintaining valve body is by valve seat
It is formed with valve nozzle, the valve seat and valve nozzle are coupled to form sealing structure, and the valve nozzle section is in the shape of a " convex ", the valve nozzle
The middle and upper part of periphery is arranged with O-ring, and the O-ring is that section is circular rubber seal, is provided with circle on the valve nozzle
Cylindrical tube and pipeline is located inside valve nozzle, the pressure maintaining valve body are internally provided with spool, and the effect of spool is control gas
The stabilization of pressure, the spool section is in the shape of a " convex ", and described spool one end is arranged inside pipeline, the other end position of the spool
In the top of valve seat, the middle lower section of the valve nozzle offers annular groove, and the compressed spring is sheathed on the middle and upper part of spool and compression
The periphery of spring is arranged with spring cup, and the middle lower end of the spool is arranged with gasket, and the gasket is in spring cup and valve seat
The side of wall, the effect of gasket are to prevent from being under pressure between spring cup and valve seat damaging.
Further, the valve seat is equipped with hickey, and the effect of hickey is easy for the installation and removal of valve seat.
Further, the valve seat is made of alloy material, and effect is: the hardness of alloy material is higher, solid resistance to
With.
Further, the valve seat is internally provided with two air inlets.
The working process of the utility model is as follows:
1) the utility model need to cooperate automobile absorber to use, by the valve seat on high pressure pressure retaining valve by the way of being spirally connected with
Inlet duct is fixedly connected；
2) inlet duct after the installation is completed, is opened and to high pressure gas is passed through inside high pressure pressure retaining valve, firstly, high pressure gas
Shunted after into valve seat inside, due to high pressure gas pressure be greater than compressed spring elastic force, high pressure gas by compressed spring into
Row compression, since compressed spring is set in spool, when compressed spring is during compression, spool is moved upwards, high pressure gas
Body is flowed out from valve nozzle；
3) when the pressure of high pressure gas be less than compressed spring elastic force when, spool moves downward, so with valve seat phase mutual connection
Touching forms sealing structure, realizes gas pressure maintaining.
The utility model has the following beneficial effects: the utility model passes through the interaction of compressed spring, spring cup and gasket,
It being not only simple in structure, design is reasonable, and gas pressure maintaining is stablized, and the more complex structure of traditional pressure retaining valve has been abandoned, and it is easy to maintenance,
Greatly reduce security risk.
