結(jié)構(gòu)及用途
該閥主要由主閥 1、調(diào)節(jié)閥2、過濾器3等組成。用于工礦企業(yè)、高層建筑中由水泵直接給排水系統(tǒng)中，具有截止閥、止回閥、電動閥和水錘消除器四種功能。尤其適用于配套自動化揚水控制系統(tǒng)，無需電氣控制器和外接動力，按常規(guī)自動啟閉，具有速閉、緩閉及吸能腔三種防止和消除水錘的功能，能有效地提高系統(tǒng)安全可靠性。滿足系統(tǒng)工程設(shè)備自動化控制要求。
主要技術(shù)參數(shù)
主要外形尺寸
注:順閥門進水方向看，法蘭中心至最右端尺寸為A1，總寬為A。
用途
調(diào)節(jié)與控制主閥的出口壓力，主閥出口壓力不因進口壓力變化而改變，亦不因主閥出口流量的變化而改變其出口壓力?？捎糜谏罱o水，消防系統(tǒng)及工業(yè)給水系統(tǒng)。
特點
閥體采用了全通道流線型設(shè)計、流體阻力小，流量大，既可減動壓也可減靜壓。自帶過濾網(wǎng)可濾掉介質(zhì)中的雜質(zhì)。
