But in the prior art, in order to which the intensity for increasing shell can be installed with reinforcing rib in its inner wall, but reinforcing rib is only It is only that interval is set on shell, causes the thickness of shell of shell still than relatively thin, intensity is lower, therefore how to improve its shell Intensity is a problem to be solved.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of vacuum booster valves, both It can be reduced interior bucket inside diameter and improve interior castability of going together again.

To achieve the above object, the utility model provides following technical solution: a kind of vacuum booster valve, including outer Shell and be fixed on shell bottom end and and the integrally formed sleeve of shell, the shell be internally provided with connection shell, the connection Convex block is fixed on shell, the surface of convex block is arc surface and encompasses circular plane.

By using above-mentioned technical proposal, components are mounted in the circular space that multiple convex blocks are constituted, and have reached reduction The case where connecting the purpose of shell inside diameter, and reducing the draw occurred in casting process appearance, improves the quality of valve body.

The utility model is further arranged to: being opened up on the convex block fluted.

By using above-mentioned technical proposal, groove can make the company of components and valve body with the male cooperation on components Connect the stability more stable, raising valve body uses.

The utility model is further arranged to: the inner wall of the shell is fixed with limit shell.

By using above-mentioned technical proposal, limiting shell can prevent components transition from protruding into shell, improve valve body and use Stability.

The utility model is further arranged to: being fixed with connecting plate between the connection shell and limit shell, and on connecting plate It is fixed with reinforcing rib.

By using above-mentioned technical proposal, reinforcing rib can reinforce connecting plate and limit the intensity of connecting plate between shell, increase Add the intensity of valve body, improves the service life that valve body uses.

The utility model is further arranged to: the junction of the shell and sleeve is provided with supporting block.

By using above-mentioned technical proposal, supporting block increases the intensity of shell and sleeve connection, increases the stability of valve body.

The utility model is further arranged to: being provided with annular groove on the sleeve.

By using above-mentioned technical proposal, annular groove improves the leakproofness that valve body uses for placing sealing ring.

The utility model is further arranged to: the sleeve is internally provided with anti-slop serrations.

By using above-mentioned technical proposal, the antiskid plate of dentation can place the valve body connecting with other parts and occur to turn It is dynamic, improve the stability that valve body uses.

In conclusion the utility model has the following beneficial effects: the utility model can reduce vacuum booster valve The appearance of draw situation in casting process, and increase the intensity of vacuum booster valve, improve the steady of vacuum booster valve Qualitative and service life.
