  1. If applied experiential formula mechanically to calculate the dynamic moment of the tri - eccentric butterfly vavle, its errors for the results would be larger. the paper, by virtue of the postulate of flow with fixed constant, eddiless of ideal liquid, calculated laplace equation by finite difference method in rectangular coordinates, gained pressure distribution on the butterfly disc section, thereby figured out its dynamic moment under each opening angle and the method was feasible for calculating dynamic moment of symmetry or not, designed the program and described the curve of dynamic moment. finally, the paper infered their laws

    採用經驗公式來計算三偏心蝶閥的水力矩,誤差比較大,本文根據三偏心蝶閥的結構特點,利用理想流體的常、無旋流,用有限差分法在角坐標系中求解拉普拉斯方程,得到蝶板截面上的壓力分佈,從而計算出蝶板在各個開度下的水力矩,設計出了求解的程序,給出了程序行的結果並進行了數據處理從而得到了水力矩曲,總結了它的變化規律。
