上海閥盛閥門制造(zao)有限公(gong)司主要生產對(dui)夾蝶(die)(die)(die)式(shi)止(zhi)(zhi)回(hui)閥，可提供(gong)對(dui)夾蝶(die)(die)(die)式(shi)止(zhi)(zhi)回(hui)閥價格，對(dui)夾蝶(die)(die)(die)式(shi)止(zhi)(zhi)回(hui)閥說明(ming)書，對(dui)夾蝶(die)(die)(die)式(shi)止(zhi)(zhi)回(hui)閥實(shi)物圖，對(dui)夾蝶(die)(die)(die)式(shi)止(zhi)(zhi)回(hui)閥結構圖，對(dui)夾蝶(die)(die)(die)式(shi)止(zhi)(zhi)回(hui)閥外(wai)形(xing)尺(chi)寸，對(dui)夾蝶(die)(die)(die)式(shi)止(zhi)(zhi)回(hui)閥執行標準，對(dui)夾蝶(die)(die)(die)式(shi)止(zhi)(zhi)回(hui)閥工作(zuo)(zuo)原理(li)，對(dui)夾蝶(die)(die)(die)式(shi)止(zhi)(zhi)回(hui)閥作(zuo)(zuo)用特點。

對(dui)夾(jia)蝶式止(zhi)回閥具有(you)結構(gou)長(chang)度(du)短，體積小重量輕(qing)，閥瓣關閉(bi)快速，水錘壓力(li)小，流(liu)道(dao)通暢，流(liu)體阻力(li)小，水平管(guan)道(dao)或(huo)垂直管(guan)道(dao)均(jun)可(ke)(ke)使用(yong)，安(an)裝(zhuang)方便，動作靈敏(min)，密封(feng)性(xing)能好，閥瓣行(xing)程短、關閥沖(chong)擊力(li)小，簡單(dan)緊湊、造型美觀，使用(yong)壽命長(chang)、可(ke)(ke)靠(kao)性(xing)高，防止(zhi)介質倒(dao)流(liu)，自(zi)動控制(zhi)等(deng)優點(dian)。該閥主要適用(yong)于(yu)(yu)城市、工業及高層(ceng)建筑給水、排水管(guan)網上。由于(yu)(yu)其結構(gou)長(chang)度(du)比一(yi)般止(zhi)回閥短，對(dui)有(you)安(an)裝(zhuang)空間限制(zhi)的(de)場所最為適用(yong)。
