无升程限制器的条状簧片阀开发

The Development of the Feather Valve Without The Valve Guard

介绍了无升程限制器的简支条状簧片阀;引出了用于簧片阀计算的“线推力”,“线性惯矩”概念;导出了简支条状簧片阀气流线推力、阀隙通流面积、簧片厚度、簧片预弯挠度计算式;提出了簧片挠度、强度、失稳、频率校核四准则。

This paper introuduces the simply supported feather spring valve without the valve guard which developped by the writer. The concepts of the linear air lift and the linear moment of inertia which are used to the calculation of the spring valve are firstly brought up. The formulars which calculating the linear air lift, the effective flow area and the thick of the spring are worked out, and the calibrating principles of the intensity, bending, Euler load, frequency of the spring are layed down.
