古学水电站装机容量为90MW,设计有两台机组进水蝶阀。进水蝶阀在机组正常运行和事故停机中起到至关重要的作用,因此蝶阀的质量与正确安装是安全运行的必要条件。文章以湖北洪城双密封蝶阀为基础,阐述了双密封蝶阀的结构特点和安装技巧。在蝶阀安装的现有经验技术之上,提出进水双密封蝶阀在某些条件限制下,依照蝶阀结构特征进行现场组装的施工工艺,对于提高安装质量与工程施工进度起到了促进作用。
Ancient Hydropower Station installed capacity of 90MW, designed to have two units into the water butterfly valve. Inlet butterfly valve in the normal operation of the unit and accident shutdown plays a crucial role, so the quality of the butterfly valve and the correct installation is a necessary condition for safe operation. Based on Hubei Hongcheng double seal butterfly valve, the article expounds the structural characteristics and installation skills of double seal butterfly valve. Based on the existing experience in the installation of butterfly valves, it is proposed that the construction process of on-site assembly according to the structural characteristics of the butterfly valve under the certain conditions and conditions of the double-sealing butterfly valve for water inflow has promoted the installation quality and the construction progress.
