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.
