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閥的結構，給出了三偏心的定義，推導出了蝶板截面的幾何方程及其性質，結果表明，沿蝶板厚度的平行截面輪廓線為標準的橢圓形，進而推導出了蝶板幾個主要截面的幾何參數（長軸、短軸）與三個偏心之間的函數關系；考慮到蝶板啟閉過程中避免與閥體及閥座發生干涉，結合蝶板的啟閉扭矩，確立了三偏心蝶閥回轉中心的適宜區域。 -
