摘　　要：筒形阀是一种新型的水轮机进水阀,它与球阀或蝴蝶阀相比较有防止机组飞逸事故扩大效果明显、减轻导叶全关时导水机构的快速破坏并减少漏水量,以及动水开启方便、所需时间短等优点,但对运行条件也有一定的要求。光照水电站是贵州省第1个拟采用筒形阀的电站,为此对装设筒形阀的可行性和必要性进行了认真的分析。Cylinder valve has some advantages comparing with ball and butter ones such as obvious effect for preventing influence enlargement of runaway accident, reducing leakage, short operation time and ease operation and etc. But its application requires some operation conditions. Guangzhao Hydropower Station is the first one that cylinder valve was adopted in Guizhou Province, the necessity and feasibility adopting cylinder valve, therefore, must be analyzed in detail.
