摘要:
长距离高落差倒虹吸管线具有V字型特点，调流阀在管线的不同位置会对管线系统压力和工程投资产生影响。以甘肃某长距离高落差的倒虹吸为例，在管线选取5个调流阀位置，借助HAMMER软件分别进行开关阀水锤模拟分析。结果表明，调流阀设置在位置2~5，管线压力基本都满足规范要求。在输水管径较小及末端出水池具有调节能力时将调流阀设置在倒虹吸管线前段可以显著降低阀后管线承压等级，减少工程投资。调流阀设置在最低点及管线后段对水锤升压影响均很小，管线最低点水锤防护设备不宜设置过多。
Abstract:
Given that the long?distance and high-drop inverted siphon pipeline exhibits V-shaped characteristics, the placement of regulating valves at various positions along the pipeline can significantly influence both the pressure distribution within the pipeline system and the overall project investment. Five regulating valve positions were strategically selected along a long-distance and high-drop inverted siphon project in Gansu Province, and a comprehensive water hammer simulation analysis was conducted for the on-off valve operation using HAMMER software. When the regulating valve was set within the range of positions 2 to 5, the pipeline pressure generally complied with the specification requirements. When the pipe diameter was relatively small and the terminal outlet pool possessed regulating capacity, positioning the regulating valve in the front section of the inverted siphon pipeline could effectively decrease the pressure level of the pipeline downstream of the valve, thereby reducing overall project costs. The regulating valve located at the lowest point and rear section of the pipeline had minimal impact on the pressure surge caused by water hammer. Therefore, the installation of water hammer protection equipment at the lowest point of the pipeline should be carefully evaluated to avoid over-protection.
