摘要
分析了氢能源汽车车载高压气动减压阀的结构和设计方法。具有锥型阀芯的车载高压气动减压阀通过阀体内部结构实现阀芯的最大开口量控制,阀的开口面积和阀位移成线性关系。建立了减压阀的静态和动态数学模型。减压阀的初始工作压力,控制压力以及最大控制压力和压力控制精度可以通过恰当地设计弹簧刚度,预压缩量和阀通径等参数来实现,定值输出减压阀可以保持出口压力基本恒定。
The structure and design method of a pneumatic high pressure-reducing valve of hydrogen vehicle are analyzed. The pneumatic high pressure-reducing valve with throttle poppet controls the maximum spool displace by the structure and the control area is proportional to the spool displacement. The initial pressure, operation pressure, the maximum pressure and its accuracy can come true by the optimal design of the spring and its compressed displacement and spool size. The pneumatic high pressure-reducing valve with throttle poppet can keep the output pressure constant. The results are useful for the design and analysis of the control valve of hydrogen vehicle.
