摘要
大型泵站通常采用卷扬式快速门、液压快速门和真空破坏阀来实现断流。通过详细论述卷扬式快速门、液压快速门和真空破坏阀断流方式的工作原理,分析比较各种断流方式的利弊和应用范围,提出在泵站实际情况允许条件下,优先选用真空破坏阀断流方式。
In large pumping stations, the winch type quick valve, hydraulic quick valve and vacuum breaking valve are usually used to realize the flow cut-off.Through the detailed discussion of the working principles of the cut-off modes of the winch type quick valve, the hydraulic quick valve and the vacuum breaking valve, the advantages and disadvantages and the application scope of various cut-off modes were analyzed and compared, and it was proposed that the vacuum breaking valve cut-off mode should be preferred under the actual conditions of the pump station.
