上(shang)海閥盛閥門制造(zao)有限公(gong)司主要生產(chan)消(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)回(hui)閥，可提(ti)供消(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)回(hui)閥價格(ge)，消(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)回(hui)閥說明書(shu)，消(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)回(hui)閥實物圖，消(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)回(hui)閥結構圖，消(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)回(hui)閥外形尺寸，消(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)回(hui)閥執行(xing)標準，消(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)回(hui)閥工作(zuo)(zuo)原理，消(xiao)聲(sheng)(sheng)(sheng)(sheng)止(zhi)回(hui)閥作(zuo)(zuo)用特點。

消聲(sheng)止回閥有法(fa)蘭連接(jie)和(he)對夾連接(jie)兩(liang)種連接(jie)方式，閥瓣(ban)采(cai)用進出口兩(liang)端中心軸(zhou)導(dao)向，啟閉(bi)靈活，定位準確，可(ke)水平安裝或垂直安裝，閥瓣(ban)采(cai)用彈簧加(jia)載，其快速的(de)關閉(bi)能有效地減少水錘(chui)壓力。密(mi)(mi)封(feng)(feng)(feng)面采(cai)用O形圈彈性密(mi)(mi)封(feng)(feng)(feng)與金屬硬密(mi)(mi)封(feng)(feng)(feng)的(de)組合密(mi)(mi)封(feng)(feng)(feng)結(jie)構，密(mi)(mi)封(feng)(feng)(feng)性能好，關閉(bi)時無噪聲(sheng)。還(huan)具有體積小、重量輕、流體阻(zu)力小、結(jie)構長(chang)度小、耐疲勞、壽命長(chang)等特點。該閥門安裝于(yu)(yu)給排水、消防(fang)、暖通(tong)系(xi)統可(ke)安裝于(yu)(yu)水泵(beng)出口處，防(fang)止回水倒流，而對泵(beng)造成損壞(huai)。

消聲(sheng)止(zhi)回(hui)閥主要零件材質如下：
