OneThere may be several reasons why the electric shut-off valve is not closed properly:
Electric Actuator Failure:The electric actuator is a key component that controls the switch of the globe valve, and if the electric actuator fails, such as motor damage, gear wear, etc., the globe valve cannot be completely closed.
Power issues:The normal operation of the electric shut-off valve requires a stable power supply**, if the power supply voltage is too low or unstable, it will affect the closing effect of the electric shut-off valve.
Problems with the globe valve itself:There may be some problems with the globe valve itself, such as poor valve sealing, loose valves, etc., which can cause the globe valve to not be fully sealed when closed.
Control Signal Issues:Problems in the signal transmission process of the control globe valve, such as signal interference, signal transmission delay, etc., will affect the closing effect of the electric globe valve.
External influencing factors:Sometimes external environmental factors will also affect the closing effect of the electric shut-off valve, such as too high pressure in the pipeline, which will cause the valve to close difficult.
IIIn order to solve the problem that the electric shut-off valve is not closed in place, the following operations can be carried out:
1. Check whether the electric actuator is working normally, and if there is a fault, it can be repaired or replaced.
2. Check whether the power supply is stable and ensure that the voltage is normal.
3. Check whether there is a problem with the globe valve itself, and if the valve is found to be poorly sealed or loose, it can be repaired or replaced.
4. Check whether the control signal transmission is normal, if there is signal interference or delay, corresponding intervention measures can be taken.
5. If the external environmental factors affect the closing effect of the globe valve, you can consider adding a pressure reduction device to solve the problem.
