Structure features for trunnion mounted ball valve
1, open and close without friction. This function completely solves the problem of traditional seals that are affected by friction between the sealing surfaces.
2, top-mounted structure. The valves installed on the pipeline can be directly checked and maintained online, which can effectively reduce the number of equipment stops and reduce costs.
3, single seat design. Eliminates the problem that the medium in the cavity of the valve will affect the safety of use due to abnormal pressure rise.
4, low torque design. Specially designed valve stems can be easily opened and closed with just a small handwheel valve.
5, wedge-shaped sealing structure. The valve is based on the mechanical force provided by the valve stem and presses the ball wedge onto the valve seat to seal the valve, so that the sealing performance of the valve is not affected by the pressure difference of the pipeline. The sealing performance is reliable under various working conditions.
6, the sealing surface of the self-cleaning structure. When the ball is tilted away from the valve seat, the fluid in the pipeline passes through 360° along the sealing surface of the ball, which not only eliminates the erosion of the valve seat by high-speed fluid, but also removes the accumulated material on the sealing surface to achieve the purpose of self-cleaning. .
