The electric ball valve is a valve that rotates around the axis of the valve stem according to the moving form of the valve flap. After the electric ball valve is used for a period of time, there are often some fault problems, so what should we pay attention to when repairing the electric ball valve? What about the matter?
The precautions for electric ball valve maintenance are as follows:
1. In the closed state of the electric ball valve, the inside of the valve body is still filled with pressurized fluid.
2. Before performing the maintenance of the ball valve, it is necessary to release the line pressure and ensure that it is in the open state. The electric ball valve needs to be disconnected from the power supply, and the actuator must be separated from its bracket.
3. Lubricating grease is also required to be lubricated during maintenance. Generally used grease should be compatible with the metal material, rubber parts, plastic parts and working medium of the ball valve.
4. For safety reasons, before the disassembly and disassembly operation of the electric ball valve, it must be confirmed that the upstream and downstream pipeline pressure of the ball valve has been removed.
When we are repairing the electric ball valve, we can follow the above maintenance method and hope to help everyone.
