Maintenance method of electric ball valve

The maintenance method of electric ball valve is as follows:

1. Regularly check the appearance and sealing performance of the electric ball valve to ensure that the valve body and valve cover are not damaged by bumps, deformation, cracks, etc., and check whether the valve seat sealing surface is worn or leaking.

2. Check whether the power cord and signal line of the electric ball valve are connected normally to ensure that the wires are in good contact, without damage and looseness.

3. Remove debris and sediment on the electric ball valve to keep the flow channel of the valve unobstructed.

4. Lubricate the electric ball valve regularly and use appropriate lubricants to ensure smooth operation of the valve. The lubricated parts include the valve stem, valve seat and sealing surface.

5. Regularly check the motor and controller of the electric ball valve to check whether the motor is running normally, whether there is abnormal noise or heating, and whether the circuit of the controller is working properly.

6. For electric ball valves that are not used for a long time, the valve should be in a semi-open state to prevent the sealing surface from being damaged due to long-term compression of the sealing surface.

7. During the maintenance process, if the electric ball valve is found to have abnormal phenomena, it should be stopped in time and repaired or the damaged parts should be replaced.

The above is the conventional maintenance method of the electric ball valve. The specific maintenance process and cycle can be adjusted according to the use of the valve and the maintenance manual provided by the manufacturer. In addition, attention should be paid to regularly checking the working status of fire prevention, explosion prevention and other safety equipment to ensure the safe operation of the electric ball valve.
