Abstract
A tire explosion-proof valve cock can solve the problem that impurities can enter the ring-shaped air outlet, and then plug the same after long time working of the present tire explosion-proof valve cock, thereby the over pressure in the tire can not be exhausted, and the explosion-proof can not function. The utility model comprises a valve cock body connected with an air intake pipe, on the outer side of which is disposed an inflation seal valve and a closing cap. Above the valve cock body is disposed a vent hole and a pressure release hole in the tire, both of which are communicated with the air intake pipe. In the pressure release hole, with which is communicated the vent hole disposed in the wall of the valve cock, is disposed a pressure-regulating valve core. The utility model is characterized in that the air intake pipe is threadedly sealedly connected with the valve cock body, and an interference fit is provided between the outer side of the valve cock body and the rubber cover, in which is arranged the vent hole. The utility model has advantages of simple structure, high safety, long service life, high explosion protection performance, ability of long time working without plugging the vent hole, and ability of preventing the tire from explosion caused by over pressure.
Description
Technical field
The utility model is particularly related to a kind of explosion-proof air valve of tyre.
Background technique
Existing automobile tyre valve cock has only inflation and sealing function, does not have the overvoltage degassing function, when tire because of inflating excessive or the exhaust in time when overvoltage takes place of travelling for a long time, blow out thereby cause, cause various security incidents.The patent No. is 200610053275.7 to disclose a kind of explosion-proof air valve of tyre, its structure is to be made of sealing cap, gasing sealed mouth, connecting tube and rubber body and superpressure outlet valve, wherein the superpressure outlet valve is to be made of valve body, adjusting double-screw bolt, seal ring, spring and protecting cover, its connecting tube is connected with valve body by protecting cover, forms annular waste air duct between protecting cover bottom and valve body.This valve cock can play the safety anti-explosive effect at the installation initial stage, but because annular waste air duct is positioned at tire outside, works long hours to enter impurity easily and stop up exhaust port, thereby can not in time discharge when making the tire overvoltage, and the result causes security incident such as blow out.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, and the exhaust port that works long hours can not stop up, long service life, the explosion-proof air valve of tyre that explosion-proof performance is good.
The utility model is achieved in that it comprises the valve cock matrix, on the valve cock matrix, be positioned at the tire outer end and be connected to gas tube, be provided with gasing sealed mouth and sealing cap in the gas tube outer end, on the valve cock matrix, be positioned at tire the inner and be provided with vent and the relief hole that communicates with the gas tube endoporus, in relief hole, be provided with adjusting pressuring valve core, on the valve cock base wall, be provided with the exhaust port that communicates with relief hole, its special way is: described gas tube is connected on the valve cock matrix by thread seal, be with gum cover in valve cock matrix outside by interference fit, described exhaust port is positioned at gum cover.
Above-mentioned explosion-proof air valve of tyre, in the valve cock matrix, between gas tube and vent and relief hole, be provided with a venting cavity, described vent and relief hole and air-filled pore are interconnected by venting cavity, it is smooth and easy by venting cavity vent to be communicated with relief hole when guaranteeing that in a single day tire overvoltage takes place, thereby realizes quick pressure releasing.
Above-mentioned explosion-proof air valve of tyre, described adjusting pressuring valve core are to be made of the slide block, thimble, spring and the adjusting screw that are located at successively in the relief hole, and described slide block withstands on the ladder place in the relief hole, releasing pressure automatically during with the overvoltage of realization tire.
Above-mentioned explosion-proof air valve of tyre is provided with sealing gasket in slip front, to improve the sealing effect of adjusting pressuring valve core, guarantees that tire reaches rated pressure.
Above-mentioned explosion-proof air valve of tyre, described valve cock matrix is to be composited by metal inner pipe and rubber sleeve.
The utility model has the advantages that: since gas tube by screw thread directly and the valve cock matrix be tightly connected, need not to be provided with again protecting cover, simplify the structure, and provide the mounting point to gum cover; Owing to be with gum cover in valve cock matrix outside, gum cover with the exhaust port cover inside, can play dustproof effect to exhaust port, effectively avoid exhaust port to enter impurity, this valve cock exhaust port that works long hours also can not stopped up, can guarantee that therefore tire can not blow out the Safety performance height because of overvoltage, long service life, explosion-proof performance is good.
