From the point of view of manufacture and application of ball valve products, the valve structure can be divided into two categories: fixed ball and floating ball.

The opening and closing part of the floating ball valve is a ball, and there is a through hole equal to the pipe diameter in the middle. The inlet end, the outlet end and the outlet end are respectively provided with a sealing seat made of PTFE, which is contained in a metal valve body. When the through hole in the ball coincides with the pipeline channel, the valve is in the open state; When the through hole in the ball body is perpendicular to the pipeline passage, the valve is closed. Valve from open to close, or from close to open, ball rotation 90 degrees angular stroke.

The opening and closing part of the fixed ball valve is a ball with two supporting shafts. There is a channel equal to the diameter of the pipe in the middle. There are two floating seats on both sides. When the ball rotates, it does not deviate from the axis of the upper supporting shaft of the ball. The supporting shaft is supported by the upper and lower sliding bearings. The valve seat is floating. Under the action of medium force, it pushes the ball to produce a contact stress, To obtain a reliable seal. Like floating ball valve, the valve rotates 90 degree stroke from open to close or from close to open.
