The working principle of is as follows: The eccentric hemisphere valve adopts the cam principle. During the whole closing process, the pressure acting on the sealing surface of the ball valve increases slowly, that is, the surface of the closing part and the valve seat are in a sealed state from separation to combination until they are fully combined. The principle of the opening process is the opposite.This has greatly improved the sealing state and sealing effect of traditional ball valves, and eccentric hemisphere valves have better adjustability, liquidity, and longer service life.
