蝶式(shi)雙(shuang)瓣消(xiao)聲止回閥(fa)主要(yao)用(yong)于凈水(shui)(shui)、源木、污水(shui)(shui)、海水(shui)(shui)等介質的(de)(de)供、排(pai)水(shui)(shui)管(guan)道(dao)上，安裝在水(shui)(shui)泵出口處，用(yong)以截斷介質的(de)(de)回流，消(xiao)除破壞性(xing)的(de)(de)水(shui)(shui)錘，保護管(guan)道(dao)、水(shui)(shui)泵的(de)(de)安全運行。其(qi)主要(yao)特點如下：1.體形小(xiao)、重量(liang)輕、結(jie)構長度只有旋啟(qi)式(shi)止回閥(fa)的(de)(de)三分之一(yi)左右(you)。2.緩(huan)閉(bi)系統(tong)性(xing)能優良，不受管(guan)道(dao)中介質的(de)(de)影(ying)響，閥(fa)瓣先速關后緩(huan)閉(bi)，可防止破壞性(xing)水(shui)(shui)錘。3.橡膠軟密封(feng)，封(feng)閉(bi)性(xing)能好，耐磨(mo)損，使用(yong)壽命長。4.橡膠緩(huan)沖，啟(qi)閉(bi)平穩，無振(zhen)動，無噪音。5.比老式(shi)止回閥(fa)六阻小(xiao)，有明顯的(de)(de)節能效(xiao)果。
