The structural principle of the ball valve is to control the on and off of the fluid by rotating the ball.

The main components of a ball valve include the ball, seat, stem and handle.

When the handle rotates, the valve stem drives the ball to rotate, thereby changing the shape of the channel in the valve body and achieving on-off control of the fluid.

The valve seat of the ball valve is usually made of elastic material, which can ensure that the valve has good sealing performance in the closed state.

When the ball rotates into contact with the valve seat, due to the elasticity of the valve seat, a seal can be formed to prevent fluid leakage. When the ball rotates to separate from the valve seat, fluid can flow through the channels in the valve body
