Description
Technical field
The utility model relates to a kind of pressure retaining valves, especially automobile absorber pressure retaining valve.
Background technique
Automobile absorber pressure retaining valve is applied in automobile absorber hydraulic system, and intracavity gas is made to be kept fixed pressure
A kind of valve, pressure retaining valve currently on the market have the disadvantage that (1) structure is complicated, and control mechanism is more, reduce pressure release valve protection system
The reliability of system, and since components are more, maintenance difficulty is big, and maintenance cost is high；(2) manufacturing cost is high.
Summary of the invention
In view of the deficiencies of the prior art, it is simple to provide a kind of structure for the utility model, processed using hexagonal iron charge and
At automobile absorber pressure retaining valve,
The technical solution of the utility model are as follows: automobile absorber pressure retaining valve, it is characterised in that: it includes valve body, spool and
Compressed spring, the section of the valve body are hexagon, and leakage port is provided at the top of the valve body, and the leakage port is in hemisphere
Shape is provided with the inner cavity of connection leakage port, the bottom of the inner cavity is provided with air inlet, described convenient for losing heart in the valve body
The bottom of leakage port is connected with spool, and inner cavity is protruded into the spool bottom, and the bottom of the spool is "convex" shaped, the spool
There are gap between bottom and inner cavity, enter for high pressure gas, what the spool was located at inner cavity has partially surrounded compressed spring,
The compressed spring extends to air inlet.
Further, the compressed spring is cylinder, and the material of the compressed spring is alloy spring steel.
Further, external screw thread is provided at the top of the valve body, the bottom of the valve body is provided with internal screw thread, facilitates peace
Installation and dismantling are changed.
Further, first boss is provided at the top of the spool, it is O-shaped to be provided with first at the top of the first boss
Sealing ring is provided with second boss at the top of the valve body, the second O-ring seal is provided at the top of the second boss.
Further, the valve body is process using hexagonal iron charge, reduces production cost.
Further, the compressed spring and the hand of spiral of internal screw thread are on the contrary, its effect is to prevent air inlet and other
The spring wire lower end surface of compressed spring is resisted when component is spirally connected.
Working principle of the utility model is: leakage port is blocked by spool usually under state, and pass through the first O-ring seal
It is sealed, is in close state, when internal pressure is increased to the pressure more than spring, under the action of high pressure gas, valve
Core is pushed, and leakage port is opened, and high pressure gas is discharged from inner cavity by leakage port, when internal pressure drops to less than spring pressure
When power, the spring return of spring, and then spool is pushed to block leakage port again, to realize the purpose of pressure maintaining.
The utility model has the following beneficial effects: the utility model can carry out pressure release to the high pressure gas of damper and pressure maintaining is grasped
Make, by spool, the collective effect of compressed spring and the first O-ring seal, without external force auxiliary and open in time, it is fast
Fast pressure release, to achieve the purpose that pressure maintaining, overall structure is simple, easy to use, and stability is good, high reliablity；Valve body uses hexagonal
Iron charge is process, and reduces production cost.
