Product Description
The eccentric semi-ball valve is consist of the valve body, eccentric shaft, valve cover, semi-ball, bushings, valve seat, and other parts, it rotates the eccentric shaft by 90 °to open/close the valve to cut off the medium, suitable for sewage disposal, petroleum, chemical, electricity and paper industries processing of slurry, slurry ash, paper pulp, alumina and other sealing tightness occasions, especially in two-phase flow medium. According to its installation structure, the eccentric semi-ball valve can be divided into a top entry eccentric semi-ball valve and side entry eccentric semi-ball valve.
The design of the eccentric ensures no friction between the valve seat and semi-ball during opening or closing, extending the valve serving life. There is a certain eccentricity between the rotation of the eccentric axis and the center of the valve body, that is, the half-ball changes the axial displacement with the change of angular displacement when it is opened and closed so that they are in a linear proportional relationship, and its motion path is a semi-parabolic trajectory. The trajectory of the hemispheric body from the lowest point to the highest point automatically wedges the seat, and the seat also automatically generates a preload depending on the elastic modulus of the material to close tightly.
Eccentric semi ball valve provides many advantages like, simple structure, lightweight, small resistance and torque, tight sealing, easy online maintenance, just open the valve cover and take out the eccentric shaft. The semicircular port has good flow performance and linear regulation performance, and impurities will not be deposited in the valve body cavity. In addition, she has the function of cutting, that is, in the closing of the media can be cut off debris, to ensure the normal opening and closing of the valve. The semi-ball and seat of the valve can be surfacing with different alloys to meet the needs of different occasions.
