Abstract:Aimed at examining the mechanical properties of the high-speed butterfly valve system, gas velocity in the gas drainage pipe and pressure on the valve surface after explosions were simulated by the Computational Fluid Dynamics (CFD) method. Based on the results of the simulation, the butterfly valve was designed and verified using the finite element method. AMEsim software simulated the dynamic properties of the triple offset butterfly valve system, achieving the fast open and shut-off characteristic of the valve. A new triple offset butterfly valve system was developed through mechanical analysis and design optimization, the fast shut-off time of less than 35 minutes was achieved through simulation and experiment.
