上海閥盛閥門制(zhi)造有限公(gong)司(si)主要(yao)生產蝶(die)(die)(die)(die)式(shi)(shi)(shi)雙(shuang)瓣(ban)(ban)(ban)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)(zhi)(zhi)回(hui)(hui)(hui)閥，可提供蝶(die)(die)(die)(die)式(shi)(shi)(shi)雙(shuang)瓣(ban)(ban)(ban)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)(zhi)(zhi)回(hui)(hui)(hui)閥價(jia)格，蝶(die)(die)(die)(die)式(shi)(shi)(shi)雙(shuang)瓣(ban)(ban)(ban)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)(zhi)(zhi)回(hui)(hui)(hui)閥說明書(shu)，蝶(die)(die)(die)(die)式(shi)(shi)(shi)雙(shuang)瓣(ban)(ban)(ban)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)(zhi)(zhi)回(hui)(hui)(hui)閥實物圖(tu)，蝶(die)(die)(die)(die)式(shi)(shi)(shi)雙(shuang)瓣(ban)(ban)(ban)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)(zhi)(zhi)回(hui)(hui)(hui)閥結(jie)構圖(tu)，蝶(die)(die)(die)(die)式(shi)(shi)(shi)雙(shuang)瓣(ban)(ban)(ban)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)(zhi)(zhi)回(hui)(hui)(hui)閥外(wai)形尺(chi)寸，蝶(die)(die)(die)(die)式(shi)(shi)(shi)雙(shuang)瓣(ban)(ban)(ban)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)(zhi)(zhi)回(hui)(hui)(hui)閥執行標準(zhun)，蝶(die)(die)(die)(die)式(shi)(shi)(shi)雙(shuang)瓣(ban)(ban)(ban)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)(zhi)(zhi)回(hui)(hui)(hui)閥工作原理，蝶(die)(die)(die)(die)式(shi)(shi)(shi)雙(shuang)瓣(ban)(ban)(ban)消(xiao)(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)(zhi)(zhi)回(hui)(hui)(hui)閥作用特(te)點。

蝶(die)式(shi)雙瓣(ban)消(xiao)聲(sheng)止(zhi)回閥(fa)(fa)主要(yao)用于凈水(shui)、源木、污水(shui)、海水(shui)等介(jie)質(zhi)(zhi)(zhi)的(de)供、排(pai)水(shui)管道上，安裝(zhuang)在(zai)水(shui)泵出口處，用以截斷介(jie)質(zhi)(zhi)(zhi)的(de)回流，消(xiao)除破壞性(xing)的(de)水(shui)錘，保護管道、水(shui)泵的(de)安全運行。其主要(yao)特點(dian)如下：1.體形小、重(zhong)量輕、結構長度只有旋啟式(shi)止(zhi)回閥(fa)(fa)的(de)三分之一左右。2.緩閉(bi)系統(tong)性(xing)能優良，不(bu)受管道中介(jie)質(zhi)(zhi)(zhi)的(de)影響，閥(fa)(fa)瓣(ban)先(xian)速(su)關后(hou)緩閉(bi)，可防止(zhi)破壞性(xing)水(shui)錘。3.橡膠軟密封(feng)，封(feng)閉(bi)性(xing)能好，耐磨(mo)損，使(shi)用壽命長。4.橡膠緩沖，啟閉(bi)平穩(wen)，無振動，無噪(zao)音。5.比老式(shi)止(zhi)回閥(fa)(fa)六阻小，有明顯的(de)節能效果。
