结构和自我屈尊的高度的工作原则迫使与幻灯片飞行员一起减少阀门(EPPRV ) 的电子灵魂压力被介绍。在三个典型灵魂电阻的抵抗和压力之间的抵抗价值公式和关系被获得。然后，仅仅考虑灵魂电阻的静态的特征分析的方法被建议，到负担的从煤气的供应的抵抗网络被建立，并且数学模型从流动率公式和流动保存方程被导出，与高压力的压缩的可能性，气体和温度在在模型考虑的扩大期间落下。最后，在 15 MPa 并且扩大操作飞行员线轴的击的一个产量压力的 1.5 公里的飞行员线轴排水量作为优化目标被拿，并且优化基于上面提及的基因算法和模型被执行。结果证明 EPPRV 的静态的特征显著地被改进。静态的特征分析和优化的想法为灵魂部件或系统的设计基于灵魂抵抗网络是珍贵的。

英文摘要：

The structure and working principle of a self-deigned high pressure electronic pneumatic pressure reducing valve （EPPRV） with slide pilot are introduced. The resistance value formulas and the relationship between the resistance and pressure of three typical pneumatic resistances are obtained. Then, the method of static characteristics analysis only considering pneumatic resistances is proposed, the resistance network from gas supply to load is built up, and the mathematical model is derived from the flow rate formulas and flow conservation equations, with the compressibility of high pressure gas and temperature drop during the expansion considered in the model. Finally, the pilot spool displacement of 1.5 mm at an output pressure of 15 MPa and the enlarging operating stroke of the pilot spool are taken as optimization targets, and the optimization is carried out based on genetic algorithm and the model mentioned above. The results show that the static characteristics of the EPPRV are significantly improved. The idea of static characteristics analysis and optimization based on pneumatic resistance network is valuable for the design of pneumatic components or system.
