Floating ball valve introduction
Ball without fixed-axis ball valve, known as the floating ball valve. Floating ball valve body has two seat ring seal, clamping a ball between them, the ball has a through hole, the diameter of the through hole equal to the pipe diameter, said full-diameter ball valve; the diameter of the through hole slightly smaller than the pipe The diameter, said reduced diameter ball valve. The ball body is free to rotate in the seat ring by means of a valve stem. When opened, the ball holes are aligned with the pipe diameter to ensure that the working medium resistance of the pipe is minimized. When the valve stem rotates 1/4 turn, the ball hole is perpendicular to the valve passage, and the ball is tightly pressed against the valve seat sealing ring on the outlet end by the pre-tightening force and medium pressure applied to the two valve seat sealing rings to ensure that the valve Completely sealed. This ball valve is a one-sided forced seal.
