漫湾电站深孔弧形闸门应用液压式水封的实践

Practice or Applying Hydraulic Water Seal to Deep Orifice Radial Gate at Manwan Station

文章介绍了我国首次应用于漫湾电站左、右岸排砂底孔弧形闸门的液压式水封装过的原理、设计和应用情况。液压式水封装置的成功应用不但可以节约金属结构设备的投资，而且将为我国解决深孔弧形闸门止水装置提供和积累经验。

For the first time nationwide,the silt orifice radial gates on both of the banks of Manwan Hydropower Station were equipped with hydraulic water seal devices. To make them clear,some problems concerning the principle,design and operating conditions are stated. Such a successful application can not only economize the investment of metal structure equipment,but afford useful experience for solving water seal problems of deep orifice radial gate as well.
