AI Technical Summary

Technical Problem

When the existing graphite gasket shakes on the contact surface, it is difficult for the metal clamping ring and the graphite gasket to tilt with the contact surface, resulting in leakage between the graphite gasket and the contact surface.

Method used

By setting two metal outer retaining rings up and down, an elastic net and a spring are connected between the two metal outer retaining rings. A metal inner retaining ring is installed inside the metal outer retaining ring, and an upper gasket is connected inside the metal outer retaining ring. A lower gasket is provided inside the metal outer retaining ring below. When the contact surface shaking, the contact surface squeezes the upper gasket and the upper metal outer retaining ring, so that the upper gasket and the metal outer retaining ring can be inclined with the contact surface. Make sure the graphite gaskets are always close to the contact surface.

Benefits of technology

Effectively prevent leakage between the graphite gasket and the contact surface, ensuring that the graphite gasket always maintains a tight fit when the contact surface shakes.
