蝶式雙瓣(ban)消(xiao)(xiao)聲止回閥主要用(yong)于(yu)凈水(shui)(shui)、源木、污水(shui)(shui)、海水(shui)(shui)等(deng)介質(zhi)的(de)供、排水(shui)(shui)管道上，安裝(zhuang)在水(shui)(shui)泵(beng)出口處，用(yong)以截斷介質(zhi)的(de)回流，消(xiao)(xiao)除破壞性的(de)水(shui)(shui)錘，保護(hu)管道、水(shui)(shui)泵(beng)的(de)安全運行。其主要特(te)點如(ru)下：1.體形小、重量輕(qing)、結構(gou)長(chang)度只有旋啟式止回閥的(de)三分之一左右(you)。2.緩(huan)閉(bi)系統性能優良，不受管道中介質(zhi)的(de)影響，閥瓣(ban)先速關后緩(huan)閉(bi)，可防止破壞性水(shui)(shui)錘。3.橡膠(jiao)軟密封(feng)(feng)，封(feng)(feng)閉(bi)性能好，耐磨損，使(shi)用(yong)壽命長(chang)。4.橡膠(jiao)緩(huan)沖，啟閉(bi)平穩，無振動，無噪(zao)音。5.比老式止回閥六阻小，有明(ming)顯(xian)的(de)節能效(xiao)果。
