蝶式(shi)雙瓣消聲止(zhi)回(hui)閥主要用于凈(jing)水、源木、污水、海(hai)水等介質的(de)(de)供(gong)、排水管道(dao)上(shang)，安(an)(an)裝在水泵出口處，用以(yi)截斷介質的(de)(de)回(hui)流，消除(chu)破壞性(xing)的(de)(de)水錘(chui)，保護管道(dao)、水泵的(de)(de)安(an)(an)全運行(xing)。其主要特點如下：1.體形小、重量輕(qing)、結構(gou)長度只(zhi)有旋啟(qi)式(shi)止(zhi)回(hui)閥的(de)(de)三分之一左右(you)。2.緩(huan)閉(bi)(bi)系統(tong)性(xing)能(neng)優良，不受管道(dao)中介質的(de)(de)影響，閥瓣先速關后緩(huan)閉(bi)(bi)，可防(fang)止(zhi)破壞性(xing)水錘(chui)。3.橡膠軟密封，封閉(bi)(bi)性(xing)能(neng)好，耐磨損，使用壽命(ming)長。4.橡膠緩(huan)沖，啟(qi)閉(bi)(bi)平穩，無振動，無噪音。5.比老式(shi)止(zhi)回(hui)閥六阻小，有明(ming)顯(xian)的(de)(de)節能(neng)效果。
