摘　　要：本文利用Bentley Hammer平台模拟工程实例,基于水锤防护需求探究各类控流消能设施的使用效果。研究发现,减压阀可以有效阻断正压水锤,调流阀可以有效阻断负压水锤,二者联用可兼顾正、负压水锤,且首末端及高点控流、长下坡段减压的组合方式更利于系统稳定;消能井(池)作为开放式系统中的特有设施,对水锤的防护和消除作用效果更加显著。Using the Bentley Hammer platform to simulate engineering examples and explore the effectiveness of various flow control and energy dissipation facilities based on water hammer protection requirements.It is found that the Pressure Reducing Valve(PRV)can effectively block the positive pressure water hammer,and the Flow Control Valve(FCV)can block the negative pressure water hammer effectively.The combination of the two measures can take into account both the positive and negative pressure water hammer.Moreover,controlling the flow at the head,the end and the high point,reducing the pressure in the long downhill section,is more conducive to system stability.In addition,the energy dissipation well(pool),as a unique facility in the open system,has a more significant effect on the protection and elimination of water hammer.
