In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals.
A kind of adjustable safety valve in liquid spare tyre, including hollow valve body, one end of the valve body is equipped with can
The other end of a kind of adjustable valve seat in liquid spare tyre of the valve of adjusting, the valve body is equipped with stomata, the inside of the stomata
Equipped with the safety valve for closing the stomata, compressed spring is equipped between the safety valve and valve seat；The side wall of the valve body is equipped with
Bleeder port.
In the application, under usual state, safety valve, which is against on stomata, under the pressure effect of compressed spring keeps sealing, when
When internal pressure is excessive, internal pressure jacks up safety valve, and internal high-pressure gas can be gone out by bleeder port at this time, when inside is pressed
After power and spring pressure balance or less than spring pressure, safety valve re-closes stomata and realizes sealing, passes through the position of regulating valve seat
Set the pressure of adjustable compressed spring.
Preferably, the valve seat is equipped with the first boss stretched out to valve inner, the safety valve is equipped with to valve
The second boss that internal portion is stretched out, the both ends of the compressed spring are respectively fitted in first boss and second boss.Structure dress
With stabilization.
Preferably, on the valve body install valve seat one end inner wall be equipped with internal screw thread, the outer wall of the valve seat with should
Internal screw thread Screw assembly, and the length of the internal screw thread is greater than the length of screw thread on valve seat, in the structure, is threadedly engaged stabilization,
And the pressure of the adjustable compressed spring of the depth by regulating valve seat, realize the adjusting of cracking pressure.
Preferably, the safety valve is safety valve made of nitrile rubber, it is at low cost, and sealing effect is good, does not need
Another encryption seal structure.
Preferably, the valve seat is copper valve seat, sealing effect is good, and intensity is high.
Preferably, the one end for assembling safety valve in the cavity of the valve body is equipped with inner convex platform, the safety valve is pressed in this
The sealing to stomata is realized on inner convex platform, the assembling structure is simple.
Compared with prior art, the utility model has the following beneficial effects: providing a kind of in liquid spare tyre
Adjustable safety valve, structure is simple, easy to assembly, can be good at realizing the control to internal pressure, and vent pressure can be with
Convenient adjustment.
Detailed description of the invention
Fig. 1 is the schematic diagram of the adjustable safety valve in the utility model.
Fig. 2 is the schematic diagram of internal structure of the adjustable safety valve in the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Referring to attached drawing 1 to attached drawing 2, a kind of adjustable safety valve in liquid spare tyre involved in the utility model,
