Hirsch kg fabrik technischer federn是一家現代化、值得信賴的專門產品供應商，該供應商從事壓力彈簧，傳動螺旋線，彎曲鋼絲產品，蝶形彈簧，特種彈簧，毛坯和半成品的製造和銷售。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動水力矩，誤差比較大，本文根據三偏心蝶閥的結構特點，利用理想流體的定常、無旋流動的假定，用有限差分法在直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動水力矩，設計出了求解的程序，給出了程序運行的結果並進行了數據處理從而得到了動水力矩曲線，總結了它的變化規律。
