摘　　要：为了研究梭式止回阀关闭时的流场特性,采用了数值仿真和对比的方法。利用ADINA软件,分别对DN100的梭式止回阀和旋启式止回阀进行流固耦合仿真计算,得出可视化结果,通过对比分析,验证了梭式止回阀在关闭过程中具有流速分布均匀,压力分布对称,流动状态稳定,阀芯受力均衡等优势,有利于其研究和推广。To research the flow field characteristics of shuttle-type check valves in closure process,numerical simulation and contrast method were adopted in it.Based on ADINA,fluid-structure interaction calculation was implemented respectively for the DN100 shuttle-type check valves and swing-type check valves so that visualization results were obtained.By contrast analysis,it derives that the shuttle-type valves have the advantages of uniform velocity distribution,symmetrical pressure distribution,steady flow state,equilibrium load on the valve core,etc,which is beneficial to their research and extension.
