AI Technical Summary
Technical Problem
The existing Y-type sealing rings of water-cooled generator brakes can only provide unidirectional sealing, requiring the installation of two, which increases production costs, and the lips are prone to wear, affecting the sealing effect.
Method used
It adopts a double V-shaped sealing ring with bidirectional concave shape, combined with a metal ring and a pressure rubber ring. The metal ring is pushed by hydraulic oil to squeeze the rubber ring to achieve bidirectional sealing. An annular groove is set on the lip to improve the sealing effect.
Benefits of technology
This reduces the number of sealing rings used, lowers production costs, and ensures a stable sealing effect even after wear, thereby improving the wear resistance and sealing performance of the sealing rings.

Abstract
本实用新型提供一种可双向密封的水轮发电机制动器密封装置，涉及水轮发电机领域，包括活塞以及套设在活塞外侧的密封圈，其特征在于：密封圈截面为双向内凹的双V型结构，密封圈的V型凹槽设置有环形支撑部，环形支撑部包括金属圈以及一体成型在密封圈V型凹槽内侧的压力橡胶圈，通过设置的双向内凹的双V型密封圈，因此在活塞上安装一个此密封圈即可对活塞的两个压力端密封，从而可以减少密封圈的使用数量，节约生产成本，同时，当密封圈与液压油缸内侧摩擦产生磨损时，密封圈中的压力橡胶圈可以推动密封圈唇边持续保持压力，使密封圈的唇边可以一直被稳定的按压密封在液压油缸的内壁上，提高密封圈的密封效果。
