The top mounted eccentric hemisphere valve utilizes an eccentric valve body, eccentric ball, and valve seat. When the valve stem rotates, it automatically centers on a common trajectory, and the closer it is closed, the better the sealing effect is achieved. The ball and valve seat of the valve are completely separated, eliminating the wear of the sealing ring and overcoming the problem of traditional ball valve seat and ball sealing surface always wearing. Non metallic elastic materials are embedded in the metal seat, and the metal surface of the valve seat is well protected. This product is particularly suitable for media such as steel, aluminum, fiber, small solid particles, pulp, coal ash, petroleum gas, etc.
1. Its structure adopts the eccentric wedge principle to achieve the purpose of locking, adjusting, and closing through the transmission mechanism. The sealing pair is a metal face ring with a hard contact seal. The double eccentric structure is located in the ball storage chamber when opening, with a large flow cross-section, and the valve is not washed out. When closing, the valve core is not washed out. When opening, the spherical surface of the valve core gradually moves along the valve seat, effectively removing scaling obstacles and achieving reliable sealing. It is particularly effective for mixed flow transportation where two-phase mixed flow is prone to scaling and solid precipitation
