摘　　要：基于FLUENT软件对3种氦气隔离阀进行流体阻断性能试验仿真模拟,分析了3种氦气隔离阀在氦气介质下实现关闭的可能性。分析不同隔离阀的流场和受力情况,发现在关闭过程中会出现压力波动以及不稳定湍流现象。最后,通过3种阀门的横向对比得到了DN 65氦气球阀在阻断流体流动方面的优势。Having FLUENT software based to simulate fluid blocking performance test of three kinds of helium isolation valves was implemented,including analyzing the possibility of closing three kinds of helium isolation valves in the helium medium.Analyzing both flow field and stress of different isolation valves shows that,the pressure fluctuation and unstable turbulence occur during the closing process.In addition,the advantages of DN 65 helium balloon valve in blocking fluid flow were obtained through laterally comparing three valves.
