摘　　要：在球阀关闭瞬间,球阀将会承受来自上游方向水锤的巨大作用力,因此对球阀与压力钢管对接的焊缝质量需要有严格的要求。结合仙居抽水蓄能电站球阀工地安装焊接过程安装空间有限的特点,对球阀各部分安装的顺序需要做出相应的合理规划,对球阀在工地安装、焊接的过程及方法进行简要阐述。At the moment when the ball valve is closed,the ball valve will bear great force of the water hammer from upstream direction,so the quality of the butt welding seam between the ball valve and the pressure steel pipe needs to be strict.Considering the limited installation space in the welding process of ball valve installation in Xianju pumped-storage power station,the installation sequence of each part of ball valve needs to be reasonably planned.in this paper,the site installation of ball valve and the process and method of welding.is briefly described.
