摘　　要：仿真分析工作以高压气动减压阀的数学模型为基础,在仿真主阀口流道时,使用软件完成了相关的工作任务,并全面剖析了其流场的特点。综合分析阀的结构设计理念后,得出以下结论:主阀口流场以均匀的形式分布,在短时间之内即能达到稳定的状态,壁面直角位置处的涡流非常小,能量损害也比较低,高压气动减压阀在不给响应速度造成任何影响的情况下,其稳定性能够保持良好的状态。通过对主阀的复位弹簧、先导阀和阀芯质量进行不断提升,能够使减压阀的稳定性得到最大限度的保证。In the simulation of the main valve port flow channel,the software is used to complete the relevant work tasks,and the characteristics of the flow field are comprehensively analyzed.After integrating the structural design concept of the analysis valve,the following conclusions are drawn:The main valve port flow feld is distributed in a uniform form,and can reach a stable state in a short time.The vortex at the right angle of the wall is very small,and the energy damage is relatively low.The high-pressure pneumatic pressure relief valve can maintain a good state without any impact on the response speed.By continuously improving the quality of the reset spring of the main valve,the pilot valve and the valve core,the stability of the pressure relief valve can be maximum guaranteed.
