摘要
在重力输水系统中,管道末端关阀检修操作如果不当,会引起关阀水锤。消除水锤的安全措施很多,但是最经济、有效的方式是延长关阀时间。对影响关阀时间的因素进行了分析,并得出了一般结论。
In a gravity pressure water conveyance system , the end of the pipeline valve maintenance operation if improper, will cause the closing valve water hammer. To eliminate the water hammer using the safety measures, the economical and effective way are to delay the time of closing the valve. The influence factors of valve closing time are analyzed and the conclusion is found.
