Abstract
The utility model discloses an anti-leakage air valve, comprising an air valve body 1, an air inlet 7, an air hole 2 and a rubber pipe 9, and also comprising a spring 3, a metal pad 4, a sealing pad 5 and a metal sheath 6 with a through hole 8, which are installed into the air inlet 7 in turn. The metal pad and the sealing pad are bonded together, and the metal sheath and the air inlet are fastened and combined. The anti-leakage air valve has the advantage of reliable seal, and the anti-leakage air valve can cause a tyre not to need to be inflated for half a year.
Description
The utility model relates to the pneumatic tire valve cock, is a kind of leakproof valve cock specifically.
Valve cock is to be used for pneumatic tire is inflated, and a kind of device that the pressurized gas of inflation rear tyre inside are no longer leaked.Its simple structure, there is an inlet hole 7 at valve body 1 center, and there is a pore 2 side, elastic rubber tube 9 of valve body 1 outer cover, sebific duct 9 is sealed inlet hole 2.During inflation, pressurized air passes through inlet hole 7, pore 2, has overcome the resistance between sebific duct 9 and the valve cock 1, enters inside tires.After having inflated, the pressure of roller tire internal high pressure gas makes sebific duct 9 that pore 2 is sealed, in order to avoid pressurized gas are released.But, not enough as precision, luminosity because unavoidable some problem of valve body 1 and sebific duct 2 manufacturing process, add the influence of sebific duct material, when tyre inner pressure was big, gas can release between sebific duct 9 and valve body outer surface.Therefore, have to often to tyre inflation.Be a disturbing thing for a long time.
The purpose of this utility model is the problem at present existence, and a kind of leakproof valve cock of good seal performance is provided.
The utility model is achieved in that the leakproof valve cock is made up of valve body 1, inlet hole 7, pore 2, sebific duct 9.In addition, it also has a spring 3, metal gasket 4, a sealing gasket 5 and a metallic sheath 6 that has through hole 8, and they put into inlet hole 7 successively.Metal gasket 4 bonds together with sealing gasket 5, leaves the air inlet gap between its cylindrical and inlet hole 7 endoporus.The cylindrical of metallic sheath 6 is fastening with the endoporus of inlet hole 7 and combines.
The utility model has the advantages that sealing is reliable, can make tire keep inflated condition for a long time.
Accompanying drawing is a specific embodiment of the present utility model.
Fig. 1 is the leakproof valve cock that is in sealing state;
Fig. 2 is the leakproof valve cock that carries out inflated condition.
During inflation, sealing gasket 5 and metal gasket 4 move to left under compressed air pressure, and pressurized air can enter tire along inlet hole 7, through hole 8, pore 2.After having inflated, metal gasket 4, sealing gasket 5 seal through hole 8 under the pressure of spring 3.Like this, even 9 pairs of pores 2 of sebific duct are poorly sealed, the gas of leakage also can be sealed by sealed pad 5, can not overflow.This leakproof valve cock is used in evidence, and bicycle tyre need not inflation in half a year.
