Structural analysis of different ball valve seats
The main function of the ball valve is to cut or close the fluid passage in the pipe. The working principle of the ball valve is to transmit a certain torque to the ball at the upper end of the valve stem by means of the driving device, and rotate it to 90° to complete the action of opening or closing the valve.
