Abstract
The utility model relates to a pressure-proof seal gasket for a valve core of an automobile. The seal gasket comprises a circular gasket body, wherein the diameter of the cross section of the circular gasket body symmetrically decreases from the middle part to the upper and lower surfaces, circular seal grooves are further symmetrically formed in the upper and lower surfaces of the circular gasket body, the surface of an inner ring of the circular gasket body is provided with an inner screw thread, and the circular gasket body is internally provided with a copper-made framework ring. The seal gasket provided by the utility model is simple in structure and good in sealing performance, and has certain strength.
Description
Technical field
The utility model relates to auto parts machinery technical field, the compressive sealed pad of especially a kind of tyre valve inside of automobile.
Background technique
Valve inside is a kind of unidirectional gas charging valve, applies morely in auto parts machinery field, is mainly used in the inflation/deflation of tire.And gasket seal is the important accessory of valve inside, common gasket seal is only ring-type, and sealing effect is common.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provide a kind of simple in structure, good airproof performance and have the compressive sealed pad of tyre valve inside of automobile of some strength.
The utility model solves the technological scheme that its technical problem adopts: the compressive sealed pad of a kind of tyre valve inside of automobile, comprise annular shim, annular shim cross-sectional diameter is by middle part surperficial Rearrangments up and down, annular shim upper and lower surface is also arranged with respectively annular seal groove, described annular shim inner peripheral surface has internal thread, and annular shim inside also has copper skeleton ring.
Preferably, annular shim is silicone rubber material.
The beneficial effects of the utility model are: the compressive sealed pad of the tyre valve inside of automobile that the utility model provides, and simple in structure, good seal performance and there is some strength.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
