Abstract
An equalizing filling valve was increased on the upper part of the tail gate to instead of the equalizing draft tube of Tianshengqiao-1 hydropower plant because the draft tube has water leakage caused by serious corrosion after 10 years operation under water. The increased equalizing filling valve operates flexibly and reliably and seals well,and is convenient for open,close and maintenance and can effectively meet the operation requirements of the tail gate.关键词
