[0011] Preferably, the material of the gasket body and the bottom gasket is carbon steel, and the outer surface of the top end of the gasket body is provided with an anti-rust layer.

[0012] Preferably, the bottom end of the bottom gasket is provided with a mounting groove, and a rubber ring is embedded in the mounting groove, wherein the rubber ring and the mounting groove are annular, and the rubber ring is made of rubber.

[0013] (Three) beneficial effects

[0014] Compared with the prior art, the spherical spring gasket structure has the following beneficial effects:

[0015] The gasket body and the bottom gasket increase the thickness of the gasket, the stress surface of the gasket body is spherical, the impact on the gasket body can be effectively reduced, the gasket is not easy to deform, the use effect and service life of the gasket are increased, the rubber pad is embedded at the bottom end of the bottom gasket, the gap during bolt installation can be effectively filled, and the buffering effect is increased.
