Electric Regulating Control Valve working principle:
The closing principle of the electric globe valve is to rely on electric thrust to rotate the valve bar, so that the sealing surface of the valve flap and the sealing surface of the valve seat are closely fitted to stop the flow of media. The electric globe valve only allows the medium to flow in one direction and is installed with directionality.
The length of the structure of the globe valve is greater than that of the gate valve, while the fluid resistance is high, and the sealing reliability is not strong during long-term operation.
1. In the closed position, the valve body is mechanically pressurized by the stem and the sealing surface of the valve flap is pressed against the valve seat.
2. When the handwheel is turned counterclockwise, the stem moves in the opposite direction and the angular plane at its bottom causes the valve body to disengage from the seat.
3. The stem continues to lift and interacts with the guide pin in the spiral groove of the stem so that the valve flap begins to rotate frictionlessly.
4. Until it reaches the fully open position, the valve stem is lifted to the limit position and rotated to the fully open position.
