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
   采用经验公式来计算三偏心蝶阀的动水力矩，误差比较大，本文根据三偏心蝶阀的结构特点，利用理想流体的定常、无旋流动的假定，用有限差分法在直角坐标系中求解拉普拉斯方程，得到蝶板截面上的压力分布，从而计算出蝶板在各个开度下的动水力矩，设计出了求解的程序，给出了程序运行的结果并进行了数据处理从而得到了动水力矩曲线，总结了它的变化规律。
