摘　　要：以大口径管道阀门为研究对象,为满足快速泄复压要求,设计了大型阀门快开系统。研究了采用比例换向阀和比例调速阀的大型阀门快开系统的稳定性;阀门在不同开度下的泄复压效果;以及系统最优的泄复压控制方案的选择。仿真结果表明:该系统满足稳定性要求;系统采用比例换向阀的泄复压性能优于采用比例调速阀的泄复压性能;采用比例换向阀的大型阀门快开系统,当阀门开度为70°时,系统的泄复压效果控制最佳。In order to meet the requirement of rapid relief of compound pressure,a large valve quick opening system was designed,and a simulation model was established to study the stability of the large valve quick opening system using proportional directional valve and proportional speed regulating valve.The relief and compound pressure effect of valve under different opening degrees;The simulation results show that the system meets the requirement of stability.The compound pressure relief performance of the system using proportional directional valve is better than that of the system using proportional speed regulating valve.Adopt the large valve quick opening system of proportional reversing valve,when the valve opening is 70,the control effect of relief and compound pressure is the best.
