摘　　要：长期以来,我国水电站水轮机进水阀选择蝴蝶阀或球阀通常以200m水头为界。民治水电站最大水头238.46m,随着新规范的出台,水轮机进水阀型式采用蝴蝶阀还是球阀还需仔细斟酌。通过对两种阀型进行技术经济比较、设计制造难度与可行性分析,认为民治水电站水轮机进水阀采用蝴蝶阀是完全可行的。For a long time, the head limit of choosing butterfly valves or spherical valves for inlet valve of turbine is 200 m as usual. The maximum head of Minzhi Hydropower Station is 238.46 m so that it should be considered carefully that choosing butterfly valves or spherical valves with new criterion coming on. After making technical and economic comparison, analyzing the difficulty of design manufacture and the feasibility of such two kinds of valves, this paper draws a conclusion that choosing butterfly valves for inlet valve of the turbine of Minzhi Hydropower Station is fully feasible.
