中文摘要	Analysis of the opening and gating of the globe valve seal at the Guangzhou pumped storage power station showed that the flexible character of the globe valve may cause the self-excited oscillations on the flow channels. The flexible character is related to the location where the pressured water flows into the globe valve's seal. Suggestions are given to eliminate the self-excited oscillations. The suggestions include changing the valve seat pressured water inlet location or using a by-pass valve. Simulations using the characteristics method verifies the feasibility of the suggestions.
