The paper deduced the seal torque of the tri - eccentric butterfly valve and gave it a qualitative analysis. the results indicated : for the tri - eccentric butterfly valve with the same caliber, theseal torque would decrease with the butterfly disc thickness increasing ; the seal torque would increase with the radial eccentricity increasing ; however, the axis eccentricity effected on the seal torque minutely ; the seal torque would increase with the half cone angle increasing appreciably of the cone which the butterfly disc belonged to
本文還對三偏心蝶閥的密封力矩作了推導並進行了定性的分析,結果表明,對于同一口徑的三偏心蝶閥,密封力矩與蝶板的厚度近似成反比;與徑向偏心距近似成正比,變化也很明顯;而軸向偏心距對密封力矩的影響不是很大;密封力矩隨著蝶板所在的圓錐半錐角的增大而有所增加。This valve being mounted in the water distribution pipes with its pilot valve being pre - setted in a fixde flow - rate which enable the pressure variation of the main body ' s upper - reach not to have an effect on the flow volume of the outlet
本閥安裝于送配水管路中,可預先設定其上之導向閥于某一固定流量,使其主閥進口壓力變化而不會影響出水口。
