摘　　要：为解决高温空气蝶阀的内部密封和高寿命问题,该文提出一种基于弹性元件理念设计涨圈的方法,以某运输飞机引气系统交叉引气活门的密封涨圈为例的开展设计、弹力计算和开口尺寸计算,并结合该活门的耐久试验验证结果,证明该设计方法能够实现空气蝶阀的内部密封和高寿命,具有合理性和可行性,能够保证为空气蝶阀的涨圈密封设计定义提供理论基础。To solve the problem of internal leakage and high endurance of high temperature Air butterfly,the paper provides a method of Piston Ring Design based on a thinking of springiness part,with an example of design definition,elasticity calculation and gap calculation for the metal piston ring of the Cross Bleed Valve(CBV)of Aero-transport Bleed Air System,and demonstrates the design method was rational and feasible and is able to meet the requirements of Internal Leakage and High Endurance Life of Air Butterfly,according to the endurance verification test results of the CBV,and provide a theoretic base for piston ring design of the Air Butterfly Valve.
