| 摘 要： | 为防止发生水锤事故,长距离管道有压自流输水系统末端设置的控制阀门关阀时间一定要充分,关阀时间由仿真数值计算确定。给出的末端阀作为边界条件的数学模型适用于蝶阀、活塞阀等诸多阀型。长距离管道自流输水系统的末端阀推荐采用活塞阀,末端阀为活塞阀的自流输水系统推荐的关阀方式是线性关阀。

| Abstract: | It is introduced in this paper that the duration of close outlet valve must be long enough for prevention the water hammer occurrence in the long pipeline with gravity flow,and the closing duration is determined by digital computation.The digital model is applicable for these types of outlet valve,such as butterfly valve,piston valve.By comparation the recommendation is given：the piston valve is moresuit for the outlet on long pipeline with gravity flow,and the linear procedure of closing valve is suggested. |
