摘　　要：为研究长距离重力流输水管道系统水锤防护设计,文章基于水锤压力理论,利用水锤波的波速、特征线方程及边界条件,建立水锤分析模型。应用该模型计算新疆准东五彩湾供水工程输水管道水锤防护的不同方案,结果表明,新疆准东五彩湾供水工程通过在管道既定位置安装双动式空气阀、超压泄压阀、液控蝶阀及双向调压塔能达到水锤防护要求。对长距离重力流输水管道水锤压力控制有一定的指导价值。In order to study the design of water hammer protection for long-distance gravity flow water pipeline systems,based on the theory of water hammer pressure,this paper uses the wave velocity,characteristic equation,and boundary conditions of water hammer waves to establish a water hammer analysis model.The application of this model to calculate different schemes for water hammer protection in the water supply pipeline of Xinjiang Zhundong Wucaiwan Water Supply Project shows that the method of installing double acting air valves,over-pressure relief valves,hydraulic control butterfly valves,and bidirectional pressure regulating towers at the designated positions of the pipeline in Xinjiang Zhundong Wucaiwan Water Supply Project can meet the requirements for water hammer protection.It has certain guiding value for controlling water hammer pressure in long-distance gravity flow water pipelines.
