液控自动闸阀是利用水泵在启动和停机过程中工作压力的变化 ,通过吸扬水管中的工作介质控制液控自动闸阀的换向控制阀 ,使闸板按照水泵工作程序自动完成启闭。该阀于 1 994年获得了国家专利 ,专利号为ZL94 2 3 792 9.2。本文介绍了液控自动闸阀的结构 ,工作原理和性能特点 ,分析了液控自动闸阀在实际工作中的使用条件
Hydraulic automatic gate valve is the use of water pumps in the process of starting and stopping the pressure changes, by sucking the working medium in the pipe control liquid-controlled automatic gate valve to the control valve so that the gate in accordance with the working procedures automatically pump open and close. The valve in 1994 won the national patent, patent number ZL94 2 3 792 9.2. This paper introduces the structure, working principle and performance characteristics of the liquid-controlled automatic gate valve. It analyzes the conditions of using the liquid-controlled automatic gate valve in practical work
