摘要

摘要确保灌溉系统可靠运行的方法之一是保护它们免受启动或停止泵站时发生的水锤（液压冲击）损坏。这可以通过创造条件来实现，在这种条件下，关闭端闸阀（EGV）不会在压力管道中产生水锤。本研究的目的是调查EGV线性关闭期间、一个断点关闭期间和间歇性关闭期间管道中发生的过程，并验证管道组合端闸阀关闭的有效性。基于实验数据和计算，本文建议采用一个断点的EGV线性闭合。

Experimental Study of the Effectiveness of a Combined Closure of the End Gate Pipeline Valve

Abstract One of the ways to ensure a reliable operation of irrigation systems is to protect them from water hammer (hydraulic shock) damage that occurs when starting or stopping a pumping station. This can be achieved by creating conditions in which a water hammer will not occur in the pressure pipeline as a result of closing the end gate valve (EGV). The aim of the present study was to investigate processes occurring in the pipeline during a linear closure of the EGV, during a closure with one break point and during an intermittent closure, as well as to verify the effectiveness of a combined end gate valve closure of the pipeline. Based on experimental data and calculations, the article recommends a linear closure of the EGV with one break point.
