摘　　要：提出罗氏应力应变公式在阀座设计中的应用,针对旋转壳,压力容器,管道等受分布载荷时,从经线应力、环向膜应力、径向应力以及在综合应力情况下零件的应力变形等方面做了详细的描述。参考这些公式的计算,有助于设计者优化阀座的尺寸设计以及阀座外径和阀体内腔间隙的控制。The application of the formula of rock stress and strain in the design of the valve seat is presented,and the warp stress,the circum-membrane stress,the radial stress and the stress and deformation of the parts are described in detail when the rotating shell,pressure vessel and pipeline are subjected to the distributed load.Referring to the calculation of these formulas can help the designer to optimize the size design of the valve seat and the control of the outer diameter of the valve seat and the clearance of the valve body.
