What are the problems encountered in the operation of the solenoid valve?

For the solenoid valve, reasonable operation is very important, so what problems will be encountered during the operation?

When the sealing ring of the metal material flanged butterfly valve is fixed on the butterfly plate, when the perforated plate is opened and closed, the material flushes its protruding surface, and the soft rubber gasket in the copper sheet is eroded. , immediately jeopardizing the sealing properties. This is where the leakage of raw materials or other substances occurs. (This is also a more common common fault) The second is the specification of the normally closed solenoid valve because the overall structure of the perforated plate is too thick and the fluid density is high. It is not suitable to be a butterfly valve below the n600 specification. Also due to the basic principle of its biaxial force structure, the sealing between the convex surface of the perforated plate and the valve flange is driven by the torque of the gear to press the valve plate to the high pressure gate valve. In the case of positive flow, the higher the working pressure of the material, the heavier the sealing extrusion. When the material flowing back through the flow channel is accompanied by the expansion of the working pressure of the medium, when the positive pressure of the enterprise between the porous plate and the valve flange is lower than the material pressure, the tightness begins to leak.

Therefore, during the operation of the solenoid valve, these problems should be solved in time.
