将透气阀圆形弹性阀片的应用结构简化为了环形结构，建立了阀片受均布载荷时的力学模型，并研究了阀片的弯曲变形。运用弹性力学原理建立了弹性阀片弯曲变形的微分方程，利用弹性阀片的边界条件，推导出了弹性阀片受均布载荷时的变形解析式，并引入了弯曲变形系数以简化其表达式，为透气阀的设计和包装应用奠定基础。

The circular elastic slice of degassing valve was simplified as ring mechanics and the mechanic model of the slice under uniformly distributed load was established to investigate its deformation. The differential equation of elastic slice's deformation was established based on flexibility mechanics. The analytical formula for the elastic slice deformation was determined utilizing boundary conditions. The bending deformation coefficient (G-r) was introduced. The purpose was to provide reference for design and packaging application of degassing valve.
