Working principle of electric plug-in valve

Electric plug-in valves are widely used in various industries. In order to better use them, it is necessary to have a detailed understanding of their working principles and usage methods.

? ? slide gate valveThe opening and closing of the valve are controlled by a gate, and the direction of movement of the gate should be perpendicular to the direction of the fluid. The gate valve can only have fully open and fully closed states and cannot be used for adjustment.

The working principle of the electric plug valve is that there is a circular hole of the same diameter on the gate plate, and the opening and closing of the gate plate is driven by an electric device to make the circular hole on the gate plate completely separate and match the diameter.

For the use of electric plug-in valves, we also need to be aware that generally the gate has two sealing surfaces, and the two sealing surfaces form a wedge shape, which is a commonly used mode. The wedge angle will vary with the parameters of the valve, usually 50 degrees. And the gate of this wedge-shaped plug-in valve can be made into a whole, generally referred to as a rigid gate; It can also be made into slightly deformed gate plates to improve its processing level and offset some angular deviations generated during the machining process, commonly known as elastic gate plates. When it is closed, the sealing surface can only seal with the pressure of the medium, which is called self sealing. Most plug-in valves use forced sealing method.
