摘要：高压气动减压阀是导弹/发射筒气源装置的重要元件,用于气源装置高压气瓶出口气体的减压与稳压。设计一种正向直动式减压阀,并建立其静态数学模型,用AMESim软件对其静态特性进行仿真分析,讨论锥形阀芯半角、敏感活塞面积和弹簧总刚度对该减压阀压力特性的影响。结果表明:锥形阀芯半角的增大能提高减压阀的调节精度;活塞面积的增大能提高调节精度,增大到一定值时,调节精度无明显提高,同时要考虑减压阀的尺寸;弹簧刚度的减小能提高减压阀的调节精度。
The high-pressure pneumatic pressure reducing valve is an important component of the missile/launcher gas source device.It is used to reduce and stabilize the outlet gas of high-pressure gas cylinder.A positive direct-acting pressure reducing valve and its mathematical model are designed.Using AMESim to simulate and analyze its static characteristics,and then discuss several influencing factors,including the half-angle of disc,piston area and total spring stiffness.The results show that the increase of the half-angle can improve the adjustment accuracy,and the valve's size must be considered;the increase of the piston area can improve the adjustment accuracy,but the adjustment accuracy is not significantly improved when it increases to a certain value;the reduction of total spring stiffness can improve the adjustment accuracy.
