上海閥(fa)盛閥(fa)門制(zhi)(zhi)造(zao)有限(xian)公司主要(yao)生產(chan)水(shui)(shui)(shui)(shui)泵(beng)(beng)(beng)控制(zhi)(zhi)閥(fa)，可提供水(shui)(shui)(shui)(shui)泵(beng)(beng)(beng)控制(zhi)(zhi)閥(fa)價格，水(shui)(shui)(shui)(shui)泵(beng)(beng)(beng)控制(zhi)(zhi)閥(fa)說明書，水(shui)(shui)(shui)(shui)泵(beng)(beng)(beng)控制(zhi)(zhi)閥(fa)實物圖(tu)，水(shui)(shui)(shui)(shui)泵(beng)(beng)(beng)控制(zhi)(zhi)閥(fa)結構圖(tu)，水(shui)(shui)(shui)(shui)泵(beng)(beng)(beng)控制(zhi)(zhi)閥(fa)外(wai)形尺寸(cun)，水(shui)(shui)(shui)(shui)泵(beng)(beng)(beng)控制(zhi)(zhi)閥(fa)執行標準，水(shui)(shui)(shui)(shui)泵(beng)(beng)(beng)控制(zhi)(zhi)閥(fa)工作(zuo)原(yuan)理，水(shui)(shui)(shui)(shui)泵(beng)(beng)(beng)控制(zhi)(zhi)閥(fa)作(zuo)用特點。

水(shui)(shui)(shui)泵(beng)控制(zhi)閥(fa)(fa)(fa)由(you)主閥(fa)(fa)(fa)、電(dian)(dian)(dian)磁(ci)(ci)導(dao)閥(fa)(fa)(fa)、針閥(fa)(fa)(fa)、球閥(fa)(fa)(fa)、單向(xiang)(xiang)閥(fa)(fa)(fa)、行程開關(guan)、微形過濾器和(he)壓力表組成(cheng)水(shui)(shui)(shui)力控制(zhi)接管系統(tong)(tong)。水(shui)(shui)(shui)泵(beng)需(xu)停(ting)止(zhi)工(gong)作(zuo)時(shi)，先由(you)進(jin)口(kou)壓使主閥(fa)(fa)(fa)關(guan)閉(bi)90%后，水(shui)(shui)(shui)泵(beng)停(ting)止(zhi)運(yun)轉(zhuan)(zhuan)。剩余10%由(you)回水(shui)(shui)(shui)關(guan)閉(bi)。可防止(zhi)水(shui)(shui)(shui)錘現(xian)象發生(sheng)。其(qi)工(gong)作(zuo)原理：當水(shui)(shui)(shui)泵(beng)工(gong)作(zuo)閥(fa)(fa)(fa)門向(xiang)(xiang)下(xia)游供(gong)水(shui)(shui)(shui)時(shi)，點(dian)此(ci)導(dao)閥(fa)(fa)(fa)全(quan)開，針閥(fa)(fa)(fa)調(diao)至(zhi)適當開度，上游水(shui)(shui)(shui)經針閥(fa)(fa)(fa)、單向(xiang)(xiang)閥(fa)(fa)(fa)進(jin)入主閥(fa)(fa)(fa)控制(zhi)室(shi)，經電(dian)(dian)(dian)磁(ci)(ci)導(dao)閥(fa)(fa)(fa)流出，此(ci)時(shi)主閥(fa)(fa)(fa)控制(zhi)室(shi)的(de)壓力保持(chi)主閥(fa)(fa)(fa)處(chu)于合適的(de)開度，保持(chi)下(xia)游正常(chang)供(gong)水(shui)(shui)(shui)。當水(shui)(shui)(shui)泵(beng)停(ting)止(zhi)工(gong)作(zuo)時(shi)，電(dian)(dian)(dian)磁(ci)(ci)導(dao)閥(fa)(fa)(fa)先關(guan)閉(bi)，主閥(fa)(fa)(fa)控制(zhi)室(shi)停(ting)止(zhi)排水(shui)(shui)(shui)，控制(zhi)室(shi)壓力升(sheng)高，主閥(fa)(fa)(fa)開始關(guan)閉(bi)。當關(guan)閉(bi)至(zhi)90%時(shi)，主閥(fa)(fa)(fa)上部(bu)行程開關(guan)輸出停(ting)泵(beng)信號，水(shui)(shui)(shui)泵(beng)停(ting)止(zhi)運(yun)轉(zhuan)(zhuan)。此(ci)時(shi)下(xia)游回水(shui)(shui)(shui)晶(jing)單向(xiang)(xiang)閥(fa)(fa)(fa)進(jin)入主閥(fa)(fa)(fa)控制(zhi)室(shi)，控制(zhi)室(shi)壓力升(sheng)高，主閥(fa)(fa)(fa)被關(guan)閉(bi)。本產品利用電(dian)(dian)(dian)磁(ci)(ci)導(dao)閥(fa)(fa)(fa)控制(zhi)，不需(xu)要(yao)其(qi)他裝置和(he)能(neng)(neng)源(yuan)。節約能(neng)(neng)源(yuan)，保養簡便(bian)，停(ting)泵(beng)平穩，廣泛用于高層建筑、生(sheng)活區(qu)等供(gong)水(shui)(shui)(shui)管網系統(tong)(tong)及城市供(gong)水(shui)(shui)(shui)工(gong)程。
