5. The paper analyzed the struture of the tri - eccentric butterfly vavle at length , defined the tri - eccentric butterfly valve , educed the geometry function and its characteristic about the section of the butterfly disc . the results indicate : the parallel contour line across butterfly disc thickness is normal ellipse , thereby eslablished function relations between its geometry parameters ( long axis and short axis ) of three primary sections of the butterfly disc and the tri - eccentricity ; in order to avoid interference between the butterfly disc and the valve seat as well as the valve body , combining the torque , we obtained the feasible range about the rotation center of the tri - eccentric butterfly vavle
   本文主要分析了三偏心蝶阀的结构，给出了三偏心的定义，推导出了蝶板截面的几何方程及其性质，结果表明，沿蝶板厚度的平行截面轮廓线为标准的椭圆形，进而推导出了蝶板几个主要截面的几何参数(长轴、短轴)与三个偏心之间的函数关系；考虑到蝶板启闭过程中避免与阀体及阀座发生干涉，结合蝶板的启闭扭矩，确立了三偏心蝶阀回转中心的适宜区域。
