Ball ValveA. Opening process
1 In the closed position, the ball is pressed tightly against the valve seat by the mechanical pressure of the valve stem.
3 The valve stem continues to rise and interacts with the guide pin in the spiral groove of the valve stem, causing the ball to begin to rotate frictionlessly.
B. Closing process
2 Continue to rotate the handwheel, and the valve stem is acted upon by the guide pin embedded in the spiral groove on it, causing the valve stem and the ball to rotate 90° at the same time.
4 In the last few turns of the handwheel, the angular plane at the bottom of the valve stem mechanically wedges and presses the ball, causing it to press tightly against the valve seat to achieve complete sealing.
