摘　　要：本文通过有限元软件Fluent对不同流量下轴流式止回阀的启闭状态进行了大量的相关研究,内容包括正向和反向介质流动下阀瓣受力情况分析、介质流量与开度的关系、介质流量与阀瓣受力情况的关系、阀门流量系数及流阻系数。给出了不同流量情况下确定轴流式止回阀开度的相关方法,对轴流式止回阀的设计具有一定的参考意义。In this paper,the finite element software Fluent is used to conduct a large number of relevant studies on the opening and closing states of axial check valves under different flow,including the analysis of the force of the disc under forward and reverse medium flow,the relationship between the medium flow and the opening,and the relationship between the medium flow and the force of the disc,valve flow coefficient and flow resistance coefficient.The relevant methods to determine the opening of axial-flow check valve under different flow conditions are given,which has certain reference significance for the design of axial-flow check valve.
