The common faults of electric plug valves are as follows:
1、 Electric plug valve cannot be opened or closed:
The possible causes of this malfunction could be power failure, motor damage, actuator failure, etc. It is necessary to check whether the power supply voltage is normal, whether the motor is running, whether the actuator is stuck, etc. After confirming the problem, corresponding repairs or replacements should be carried out.
2、 Electric plug valve switch insensitive:
This issue may be due to the wear and tear of the components inside the actuator caused by long-term use, resulting in the insensitive opening and closing of the plug valve. At this point, it is necessary to clean the components inside the actuator or replace damaged parts.
3、 Electric plug valve leakage:
This malfunction may be caused by aging, loosening, or damage of the sealing ring. It is necessary to check whether the sealing ring is intact, whether there are cracks, whether it is loose, and if there are any problems, it needs to be replaced in a timely manner.
4、 Electric plug valve motor overheating:
This malfunction may be caused by excessive motor load or motor damage. Need to check if the motor load is too high and if there is any abnormal noise. If there is, the motor needs to be replaced.
Exclusion method:
1. Check if the power supply is powered on, if the power supply is normal, and if the power supply is stable.
2. Check if the motor is damaged, running normally, and if the motor circuit is connected.
3. Clean the components inside the actuator and replace damaged parts.
4. Check whether the sealing ring is intact, whether there are cracks, whether it is loose, and if there are any problems, it needs to be replaced in a timely manner.
5. Check if the motor load is too high and if there is any abnormal noise. If there is, replace the motor.
6. According to the specific fault situation, choose the corresponding maintenance method for repair or replacement.
