| Abstract: | Through analysis of fatigue damage fault of pole of high pressure control valve for 40MW turbine in the gas-steam cycle generation system of Jigang Group Co.,Ltd,it was found out that valve discs were unstable in low load,therefore,air flow impact and air flow vibration oc-curred,resulting in quick damage of the valve pole.According to fault cause,the relevant recon-struction measures were given.An optimization reconstruction was made in turbine running and on structure of the valve,which solved the fault successfully. |
