上(shang)海閥盛閥門(men)制造有(you)限公司(si)主要(yao)生產(chan)消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)(zhi)回(hui)(hui)(hui)(hui)閥，可提供消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)(zhi)回(hui)(hui)(hui)(hui)閥價(jia)格，消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)(zhi)回(hui)(hui)(hui)(hui)閥說(shuo)明書，消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)(zhi)回(hui)(hui)(hui)(hui)閥實物圖(tu)，消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)(zhi)回(hui)(hui)(hui)(hui)閥結構圖(tu)，消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)(zhi)回(hui)(hui)(hui)(hui)閥外形尺寸(cun)，消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)(zhi)回(hui)(hui)(hui)(hui)閥執(zhi)行(xing)標準，消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)(zhi)回(hui)(hui)(hui)(hui)閥工作原理，消(xiao)(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)(zhi)回(hui)(hui)(hui)(hui)閥作用特點(dian)。

消聲(sheng)止回(hui)閥有(you)(you)法蘭連(lian)接和對夾連(lian)接兩種(zhong)連(lian)接方(fang)式(shi)，閥瓣采用(yong)進出(chu)口兩端中心軸導(dao)向，啟閉(bi)靈活，定(ding)位準確，可(ke)水(shui)(shui)平安(an)裝或(huo)垂直安(an)裝，閥瓣采用(yong)彈(dan)簧加載，其(qi)快速的關(guan)閉(bi)能有(you)(you)效地(di)減少(shao)水(shui)(shui)錘壓力。密封(feng)(feng)面采用(yong)O形圈彈(dan)性密封(feng)(feng)與(yu)金屬硬密封(feng)(feng)的組合(he)密封(feng)(feng)結構，密封(feng)(feng)性能好(hao)，關(guan)閉(bi)時(shi)無噪聲(sheng)。還具有(you)(you)體積小、重量輕、流體阻力小、結構長度小、耐疲勞、壽命長等特點。該閥門安(an)裝于給(gei)排水(shui)(shui)、消防、暖通系統可(ke)安(an)裝于水(shui)(shui)泵(beng)出(chu)口處，防止回(hui)水(shui)(shui)倒流，而(er)對泵(beng)造成損壞(huai)。
