液压技术在电站尾水闸门止水中的应用

Application of the Hydraulic Pressure in Water Seal of the Tail Gate of a Hydro-Power Station

当水电站尾水位高于厂房地平面时，如果尾水闸门不能止水，势必影响电站的检修和安全。将液压技术应用于尾水闸门的止水，是解决这个问题的有效办法，并就此介绍了隆回县木瓜山水库一级电站尾水闸门应用液压止水装置的结构原理、主要技术参数、操作方法和应用效果。

When the tail water level is higher than the ground of a hydro-power plant, the repairing and safety of the plant will be affected without water seal in the tail gate. The application of the hydraulic pressure in water seal of the tail gate is a effective method for solving the problem. The structure principle,operation and practical effects of the hydraulic presure water seal set applied in the tail gate of the first stage hydro-power plant of the Muguasan Reservoir in Longhui County have been introduced in this paper.
