A double-sealed compensated ball valve seat

Abstract

This utility model relates to the field of combined ball valve technology, specifically a double-sealed compensating ball valve seat, including a connecting valve body fixedly installed on the left and right sides of the ball seat valve body. A ball valve is rotatably installed inside the ball seat valve body, and a hard sealing ring is fixedly sleeved on the side of the connecting valve body near the ball seat valve body. Through the elastic pressure of a spring on the soft sealing ring, the soft sealing ring can slide inside the connecting valve body to squeeze and contact the ball valve, achieving a flexible contact seal between the soft sealing ring and the ball valve. This isolates some solid particles in the water. Combined with the hard contact sliding between the hard sealing ring and the ball valve, the remaining small amount of solid particles can be blocked and retained in the annular groove. As the valve stem rotates, driving the ball valve to rotate, water enters the annular groove through staggered channels. The water flow carries away the solid particles, reducing wear on the ball valve and ensuring better normal operation.
