1. Lip Optimization: under peripheral pressure, the lip and groove surface fit more closely, and the higher the pressure, the better the lip sealing.
2. The fan-shaped supporters, in the premise of increasing the strength of the sealing ring, can shrink and expand in radial direction with the sealing ring.
