Turbine main steam valve
Thread Content
When the turbine is operating normally, is there any return flow for the quick-shut oil of the main steam valve? Where does the oil return to? It shouldn’t be dead oil, right?
There is no return oil; you’ll understand this by looking at the structure of the quick-shut valve. Of course, a little oil leakage from time to time is not considered an issue.
The quick-shut valve does not have oil return, while the oil actuator of the control valve does have oil return
That T1 port is for returning oil, right? The pressure relief occurs through the oil supply pipeline, right?
