摘　　要：乌弄龙水电站在汛期时具有一定的泥沙含量,为有效地减少机组停机时导叶漏水量,减轻导水机构的空蚀和泥沙磨损,提高机组运行可靠性和灵活性,水轮机设置了筒形阀。文章就水轮机设置筒形阀后进水口快速闸门的设置、机组防飞逸措施、筒形阀液压系统的设置、厂房尺寸的调整等问题进行了深入探讨,可供其它工程参考。The Wunonglong hydropower station has certain silt content in flood period.Cylinder valves are provided for turbines so as to reduce the water leakage in guide vane during shutdown of units,decrease cavitation and sand abrasion of distributors,and increase the operation reliability and flexibility of units.This paper deeply discusses the issues resulted from provision of cylinder valves and in respects of intake emergency gate installation,the anti-runaway measures of units,the provision of hydraulic system for cylinder valves,and the adjustment of powerhouse size,etc.,which can provide reference for the other projects.
