This article analyes the instance of triple eccentric butterfly valve sealing face interference or sealing pressure uniformity from space connection. Reckon the interference quantity in the different case of eccentricity parameter using solidworks, then find out the low of choosing the eccentricity parameter by analyzing the curves among interference quantity.%分析了三偏心蝶阀密封副发生干涉及密封副密封比压相对均匀的情况。运用Solidworks软件得出了不同参数选取时关闭阀门产生的干涉量。通过对干涉量曲线的分析探讨三偏心蝶阀密封副相关参数选取的规律。
