摘要
针对具体工程提出了利用复合式排气阀进行长距离输水系统水锤防护的措施.结果表明:复合式排气阀可避免因液体汽化形成的断流弥合水锤,大幅度降低水锤暂态过程中管路最高正压、最低负压的绝对值;长距离输水系统应在缓闭阀出口、管路最高点、局部凸起点以及大坡度长距离上升段的适当位置安装复合式排气阀.
Protection measures for water hammer in long-distance water transfer system using compound air valve was proposed based on a certain concrete project and the results showed that cavities collapsing can be avoided and the absolute values of both maximum positive pressure and minimum negative pressure can be reduced obviously. In order to work effectively, compound air valves should be installed reasonably.
