摘　　要：该文研究了一种商用飞机液压系统用优先阀。针对客户提出传统的先导式优先阀不能满足高安全性、高可靠性要求,特攻关对比后研究出一种直动式优先阀。通过Fluent软件仿真、弹簧匹配以及阻尼环设计等手段完成直动方案设计,试验验证满足性能及稳定性要求。This assay focused on E-style priority valve of commercial aircraft hydraulic system. As customers put forward that the pilot style priority cannot meet the requirements of high security and reliability, the E-style priority valve was designed after tackled key problem and made comparisons. Fluent software simulation, spring fitting, damping ring design and etc are used in this schematic design. The require- merits of performance and stability are verified via test. The E-style priority Valve has completed Key Design Review and achieved the equipment delivery. As the pioneer structural design, it has high promotional value.
