Abstract
The utility model discloses an anti-explosion safety valve for a tyre. The pipe wall of an air faucet is connected with a valve body, and a thimble seat whose bottom is provided with a through hole is arranged in the valve body. A sealing pad whose middle part is provided with a through hole is arranged on the inner bottom surface of the thimble seat, and a thimble whose lower part is provided with a clamping head is arranged in the thimble seat. A restoring spring is sheathed on the thimble, and the upper part of the thimble seat is connected with a screw cap whose top part is provided with a vent hole. The screw cap is also connected with the inner wall of the valve body by threads, and the air outlet at the bottom of the thimble seat is communicated with a main air passage. The utility model has the advantage that a tyre can be deflated by the vent hole of the anti-explosion safety valve for a tyre when the internal pressure of the tyre achieves a certain value. Therefore, the utility model fundamentally solves the anti-explosion problem of the tyre.
Description
The utility model belongs to a kind of automobile tyre explosion protection, particularly a kind of tire anti-explosion safety valve.
The phenomenon that self-propelled vehicle is blown out under steam happens occasionally, and this phenomenon exists certain risk.Particularly during automobile turning, blowing out to cause the serious consequence of overturning.Therefore, tire anti-explosion is a problem anxious to be solved.Existing explosion-protection equipment of tyre is the explosion-proof ability that the suit protective wire strengthens tire on the inner tube of a tyre, but the trouble-proof tire of this structure is explosion-proof limited in one's ability, and when tyre inner pressure reached certain value, tire also can explosion.Therefore, this trouble-proof tire can not fundamentally solve the tire anti-explosion problem.
The purpose of this utility model is to overcome the deficiencies in the prior art part, and the tire anti-explosion safety valve that a kind of explosion-proof performance is good, guarantee traffic safety is provided.
The utility model is achieved in that it is connected with valve body existing the wheel on the tube wall that nausea chews, in valve body, there is a bottom to have the thimble seat of through hole, the packing seal that a through hole is arranged in the middle part of being placed with on the inner bottom surface of thimble seat, in thimble seat, be placed with the bottom thimble of dop is arranged, be set with retracing spring on the thimble, be connected with the nut that a deflation hole is arranged at the top on thimble seat top, nut also is connected with valve interior wall by screw thread, and the air gate of induction opening that said gas is chewed and thimble seat bottom communicates with main gas circuit respectively.
According to above-mentioned tire anti-explosion safety valve, the through hole on the said packing seal is taper.
According to above-mentioned tire anti-explosion safety valve, said valve body and thimble seat are one.
Since when tyre inner pressure reaches certain value, can be by the pore venting of this tire anti-explosion safety valve.Therefore, this tire anti-explosion safety valve explosion-proof performance is stable and safe and reliable, has fundamentally solved the tire anti-explosion problem, and simple in structure, cost is low.
The drawing explanation:
Fig. 1 is a structural representation of the present utility model.
Provide embodiment of the present utility model below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model has a gas to chew 8 and tube wall 9, a valve body 1 that communicates with main gas circuit by through hole 10 is arranged on tube wall 9, said valve body 1 and tube wall 9 are that cylindrical shape, bottom are for conical for one or weld together and its top, the thimble seat 2 that a through hole 2A is arranged bottom being placed with in valve body 1, (said valve body 1 and thimble seat 2 also can be made as one), be placed with seal gasket 5 at thimble seat 2 inner bottom parts, there is a conical through-hole 5A at the middle part of seal gasket 5, and the outer rim of thimble seat 2 is set with O-ring seal 4, with anti-gas-leak.In thimble seat 2, be placed with the bottom thimble 3 of two or three dop 3A is arranged, and the needle point of thimble 3 is passed by through hole 5A on the seal gasket 5 and through hole 2A, be set with retracing spring 6 on the thimble 3 and be stuck on the dop 3A, on thimble seat 2 by being threaded or being hinged with the nut 7 that a deflation hole 7A is arranged at the top, with the sealing of the through hole 5A on the seal gasket 5, the top of said nut 7 is connected with valve body 1 by screw thread nut 7 by spring 6, thimble 3.
When real work, when tyre inner pressure increased to certain value, gas, was backed down thimble 3 to thimble 3 by main gas circuit, through hole 10, and gas is entered in the valve body 1 by through hole 2A, 5A, was discharged by nut 7 upper air-vent 7A again.When tyre inner pressure reduced to normal value, retracing spring 6 resetted thimble 3, with pore 5A sealing, thereby played the effect of decompression explosion-proof.
In the above-described embodiments, said valve body 1 and internal part also can be arranged in the main gas circuit that gas is chewed the below, and have a through hole that gas is chewed with main gas circuit on the valve body 1 to communicate, and a pore is arranged on tube wall 9, will be drawn by the gas that the pore 7A on the nut 7 discharges.
Claims (4)
1, a kind of tire anti-explosion safety valve, comprise that gas is chewed, tube wall, it is characterized in that, on tube wall, be connected with valve body, in valve body, there is a bottom to have the thimble seat of through hole, the packing seal that a through hole is arranged in the middle part of being placed with on the inner bottom surface of thimble seat, in thimble seat, be placed with the bottom thimble of dop is arranged, be set with retracing spring on the thimble, be connected with the nut that a deflation hole is arranged at the top on thimble seat top, nut also is connected with valve interior wall by screw thread, and the air gate of induction opening that said gas is chewed and thimble seat bottom communicates with main gas circuit respectively.
2, tire anti-explosion safety valve according to claim 1 is characterized in that, the through hole on the said packing seal is taper.
3, tire anti-explosion safety valve according to claim 1 and 2 is characterized in that, said valve body and thimble seat are one.
4, tire anti-explosion safety valve according to claim 1 and 2 is characterized in that, is set with O-ring seal on the outer rim of thimble seat.
