摘　　要：通过对采用气压式调压室作为水锤防护措施的不同类型补给水工程的比较计算,指出目前存在的水泵出口阀门类型选择的误区,介绍正确选择与不同类型补给水工程路由相适配的水泵出口阀门类型的原则,给出气压式调压室边界条件的数值模型和不同工程的比较计算结果,为设计者提供了此类工程阀门选择的科学依据。It is indicated in this paper that there is the misunderstanding on selection the type of pump outlet valve when design the delivery pipeline with pneunmatic surge chamber for precaution of water hammer. By comparison the computation results on severial delivery system in some projects, both the numerical model on the delivery pipeline with pneumatic surge chamber and the selection principle on the type of pump outlet valve are explained in this paper.
