摘　　要：构建大型混合煤气压力调节阀的三维流道模型,采用CFD软件分析大型煤气压力调节阀的动态特性,应用有限元软件对建立的调节阀三维模型进行模态分析,得到其模态振型和频率,在此基础上讨论大型混合煤气压力调节阀的抗震性能。分析表明:其最低固有频率大于一般的地震频率,在地震期间,不会发生共振,具备良好的抗震性能。The flow channel model of large mixed gas pressure control valve was established. CFD software was used to analyze the dynamic property. The three-dimensional model of control valve was also analyzed by finite element software, obtaining frequency and mode shapes. On the basis, the anti-earthquake performance was discussed. The research indicates that the lowest natural fre- quency is greater than the general frequency of earthquakes, so resonance can＇t be occurred during earthquakes. It has excellent anti- earthquake performance.
