工程中空气阀防护停泵水锤的应用

Application of Composite Air Valves in Water Transfer Project

以北方某工程为例,介绍了复合型空气阀在停泵水锤防护方面的应用,并在工程中对空气阀口径和安装位置的选择作了详细的计算,根据计算结果进行停泵水锤模拟分析,得出应用复合型空气阀防护停泵水锤可以有效控制负压和防止断流弥合水锤的发生.

Faking certain water transfer project in North China as example the application of com posite air valves for protecting against pump-stopping water hammer was described. The detailed calculation for the size of air valves and the choice of installation positions was carried out. Based on the simulation analysis of pump-stopping water hammer according to the calculation result, it can be shown that the application of composite air valves can effectively control the negative pressure and prevent the occurrence of water hammer while cavities collapsing.
