AI Technical Summary
Existing high-pressure resistant gaskets are prone to falling off and leaking under high temperature and high pressure conditions.
A high-pressure resistant sealing gasket was designed. The combination structure of the groove, the slide rod and the top block prevents it from falling off. The flexible graphite gasket and the metal strip winding structure improve the sealing effect, enhance mechanical strength and compression resilience.
It effectively prevents the gasket from falling off, improves the sealing effect and service life, and ensures no leakage under high temperature and high pressure environments.
