How to set the lifting pressure of the turbine exhaust safety valve
Thread Content
Since the exhaust gas safety valve does not have a lifting hole after installation, it is impossible to remove the valve. Moreover, the valve is large (DN300); for valves larger than DN250, the inspection department requires on-site calibration (just like with boiler safety valves). I would like to ask everyone how to calibrate the safety valves on turbine exhaust gas pipes – are there any relevant standards? Is it set like a boiler safety valve? Will it cause problems with the turbine equipment?
It should be called a waste steam safety valve; the pressure can be set on-site
