摘　　要：提出了一种新的止回阀控制结构,可用于矿井排水系统骤停时瞬态流动控制及水锤防护,利用合理的阀流型以及调速液压缸系统,操控阀板关闭过程。经过计算仿真结果显示,利用该阀可以有效控制水锤压升。Proposed a new check valve control structure for mine drainage system, which can be used to control the transient flow and water hammer when the system stopped suddenly. Using reasonable valve structure and the regulating speed cylinder system, we can control the valve closing as we wanted. The result of the simulation shows that the valve can effectively decrease the water hammer oressure.

关 键 词：瞬态流 止回阀 水锤 软件仿真
