在距离较长的输水管路中，单个阀门对水锤的控制效果会逐渐减弱。因此，通过在管路中增设阀门，将管路分解为两段进行管理，利用水锤波在传播过程中的独立性和叠加性，制造人工波源，对管路中的水锤情况进行有效控制。以MATLAB软件为工具进行数值模拟计算，对采用双阀协调方式和双阀动作方式控制水锤的影响因素进行研究。结果表明，双阀协调操作有利于管路中水锤问题的改善；结合单阀连续两阶段调节的优势，将双阀也均进行连续两阶段的关闭，发现对管路中水锤的最大压强和最小压强均起到了更好的控制作用。

The control effect of a single valve on water hammer gradually decreases in the long distance water pipelines. Therefore, the pipeline was divided into two sections for management by adding a valve, and an artificial wave source was created to effectively control the water hammer condition in the pipeline by utilizing the independence and superposition of the water hammer wave in the propagation process. MATLAB software was used to carry out numerical simulation calculation, and influencing factors of adopting double- valve coordination mode and double-valve action mode were studied. The double-valve coordination operation was beneficial to the improvement of the water hammer problem in the pipeline. Combined with the advantages of continuous two-stage adjustment of a single valve, the double valves were also closed in two consecutive stages. It was found that the maximum pressure and minimum pressure of the water hammer in the pipeline were better controlled.
