Turbine quick-shut valve
Thread Content
There is a question: should the quick-shut valve shutdown test be conducted with the valve in the open position or in the closed position?； Additionally, how is the test oil controlled, and how are the experimental results determined?
The test oil is used while the unit is operating normally to check whether there is any sticking in the quick-shut valve, as its range of movement is relatively small. Therefore, it basically will not affect the normal operation of the unit. The shut-off valve tripping test is conducted with the unit shut down. This is the biggest difference between the two.
The quick-close valve locking test must be carried out with the machine shut down! ! !
The quick-shut valve tripping test is carried out after the static debugging prior to startup; it is also possible to prepare a separate quick-shut oil and conduct the tripping test using it. In short, it needs to be done at the time of activation; otherwise it makes no sense.
