蝶式雙(shuang)瓣(ban)消聲止回閥(fa)(fa)主要(yao)用(yong)(yong)于凈(jing)水、源木、污水、海水等介(jie)質(zhi)(zhi)的供、排水管(guan)道上，安裝在水泵出口(kou)處(chu)，用(yong)(yong)以截斷介(jie)質(zhi)(zhi)的回流(liu)，消除破(po)壞性(xing)(xing)的水錘(chui)，保護(hu)管(guan)道、水泵的安全運行。其主要(yao)特點如下：1.體形小、重量輕、結構長(chang)度只有旋啟(qi)式止回閥(fa)(fa)的三分之一左右。2.緩閉系統性(xing)(xing)能(neng)優良，不受管(guan)道中介(jie)質(zhi)(zhi)的影(ying)響，閥(fa)(fa)瓣(ban)先速關后緩閉，可防止破(po)壞性(xing)(xing)水錘(chui)。3.橡(xiang)膠軟密封，封閉性(xing)(xing)能(neng)好，耐磨損，使用(yong)(yong)壽(shou)命長(chang)。4.橡(xiang)膠緩沖，啟(qi)閉平穩(wen)，無振(zhen)動，無噪(zao)音(yin)。5.比老式止回閥(fa)(fa)六(liu)阻小，有明顯的節能(neng)效果。
