上海閥(fa)(fa)盛閥(fa)(fa)門制(zhi)(zhi)造有限公司主要(yao)生產水泵(beng)(beng)控制(zhi)(zhi)閥(fa)(fa)，可提(ti)供水泵(beng)(beng)控制(zhi)(zhi)閥(fa)(fa)價格(ge)，水泵(beng)(beng)控制(zhi)(zhi)閥(fa)(fa)說明(ming)書，水泵(beng)(beng)控制(zhi)(zhi)閥(fa)(fa)實物圖，水泵(beng)(beng)控制(zhi)(zhi)閥(fa)(fa)結構圖，水泵(beng)(beng)控制(zhi)(zhi)閥(fa)(fa)外形尺(chi)寸，水泵(beng)(beng)控制(zhi)(zhi)閥(fa)(fa)執行(xing)標準(zhun)，水泵(beng)(beng)控制(zhi)(zhi)閥(fa)(fa)工作(zuo)原理，水泵(beng)(beng)控制(zhi)(zhi)閥(fa)(fa)作(zuo)用特點。

水(shui)(shui)(shui)(shui)泵控(kong)(kong)制(zhi)閥(fa)由主(zhu)(zhu)閥(fa)、電磁導(dao)閥(fa)、針閥(fa)、球閥(fa)、單向閥(fa)、行(xing)程(cheng)(cheng)開關(guan)(guan)(guan)、微形過濾器和(he)壓(ya)(ya)力表組成水(shui)(shui)(shui)(shui)力控(kong)(kong)制(zhi)接管系統。水(shui)(shui)(shui)(shui)泵需(xu)(xu)停(ting)(ting)止(zhi)(zhi)工作(zuo)時(shi)，先由進口壓(ya)(ya)使主(zhu)(zhu)閥(fa)關(guan)(guan)(guan)閉(bi)90%后(hou)，水(shui)(shui)(shui)(shui)泵停(ting)(ting)止(zhi)(zhi)運(yun)轉(zhuan)。剩余10%由回(hui)水(shui)(shui)(shui)(shui)關(guan)(guan)(guan)閉(bi)。可防止(zhi)(zhi)水(shui)(shui)(shui)(shui)錘現象發生(sheng)。其工作(zuo)原(yuan)理：當水(shui)(shui)(shui)(shui)泵工作(zuo)閥(fa)門向下(xia)游(you)供(gong)水(shui)(shui)(shui)(shui)時(shi)，點此(ci)導(dao)閥(fa)全(quan)開，針閥(fa)調至適當開度(du)，上(shang)游(you)水(shui)(shui)(shui)(shui)經針閥(fa)、單向閥(fa)進入主(zhu)(zhu)閥(fa)控(kong)(kong)制(zhi)室(shi)，經電磁導(dao)閥(fa)流出(chu)，此(ci)時(shi)主(zhu)(zhu)閥(fa)控(kong)(kong)制(zhi)室(shi)的壓(ya)(ya)力保(bao)持主(zhu)(zhu)閥(fa)處(chu)于(yu)合適的開度(du)，保(bao)持下(xia)游(you)正常供(gong)水(shui)(shui)(shui)(shui)。當水(shui)(shui)(shui)(shui)泵停(ting)(ting)止(zhi)(zhi)工作(zuo)時(shi)，電磁導(dao)閥(fa)先關(guan)(guan)(guan)閉(bi)，主(zhu)(zhu)閥(fa)控(kong)(kong)制(zhi)室(shi)停(ting)(ting)止(zhi)(zhi)排水(shui)(shui)(shui)(shui)，控(kong)(kong)制(zhi)室(shi)壓(ya)(ya)力升高(gao)，主(zhu)(zhu)閥(fa)開始關(guan)(guan)(guan)閉(bi)。當關(guan)(guan)(guan)閉(bi)至90%時(shi)，主(zhu)(zhu)閥(fa)上(shang)部(bu)行(xing)程(cheng)(cheng)開關(guan)(guan)(guan)輸出(chu)停(ting)(ting)泵信號，水(shui)(shui)(shui)(shui)泵停(ting)(ting)止(zhi)(zhi)運(yun)轉(zhuan)。此(ci)時(shi)下(xia)游(you)回(hui)水(shui)(shui)(shui)(shui)晶(jing)單向閥(fa)進入主(zhu)(zhu)閥(fa)控(kong)(kong)制(zhi)室(shi)，控(kong)(kong)制(zhi)室(shi)壓(ya)(ya)力升高(gao)，主(zhu)(zhu)閥(fa)被關(guan)(guan)(guan)閉(bi)。本產品利(li)用電磁導(dao)閥(fa)控(kong)(kong)制(zhi)，不需(xu)(xu)要其他裝置和(he)能(neng)源。節約(yue)能(neng)源，保(bao)養(yang)簡便，停(ting)(ting)泵平穩(wen)，廣泛用于(yu)高(gao)層建筑、生(sheng)活區等供(gong)水(shui)(shui)(shui)(shui)管網系統及城(cheng)市供(gong)水(shui)(shui)(shui)(shui)工程(cheng)(cheng)。
