How to deal with internal leakage in the bypass valve of a control valve? The medium is medium-pressure water, and the key issue is that this pipeline cannot be shut down
You mean the bypass line of the deoxygenated water pressure control valve, right? It’s not possible to handle it during normal production; first use the pressure control valve to regulate the pressure, prepare the necessary parts, and then carry out the replacement when production is stopped
Now it’s affecting the pressure of the medium-pressure water; the motor current is approaching its limit value
There really isn’t a good solution for this; you can secure the auxiliary valve in place and reduce the setting of the control valve to regulate the flow rate.
The control valve doesn’t leak at all, and the bypass line can’t get stuck either :L
With a pressure of over 60 kilograms, it’s difficult to handle this online; moreover, is it a stop valve?
Install an orifice plate in the circulation line of the standby pump; determine the appropriate size for the orifice plate, and then start the standby pump
We installed 3 manual valves on this cross-line valve; we were afraid of leaks in the past
Under normal operating conditions, it is impossible to address the leakage points in the bypass line of the water supply control valve; thus, operations must be stopped to carry out repairs! The impact on production isn’t very significant either!
What do you mean? Are you referring to the pre-heating line for pump motors?
There are so many valves in a row; can some more be added at that location?
