The main operating problem of three kinds of cut-off device, such as vacuum breaker, flap valve and rapid-drop gate, is discussed.
针对真空破坏阀、拍门和快速闸门等3种断流装置在生产运用中的情况,分析存在的主要问题,提出了安全、可靠的改进途径,设计发明了新型活页闸门,该闸门在下落过程中允许门扇开启使部分水流通过,这一措施大大减小了水流对闸门的推力,使闸门两侧的摩擦力下降,最终使落门力大大增加而达到快速关闭断流的目的,再利用泵站检修闸门完成止水功能。
This paper utilizes interior information redundancy of the control system and applies fault tolerant control technique to the design of the control system of optimal fast valving The results show that the reliability of system is increased ren arkably
