限流止回閥功能和作用：

一.限(xian)(xian)流(liu)(liu)(liu)功(gong)能(neng)該閥(fa)(fa)安裝于(yu)(yu)水(shui)(shui)泵(beng)出(chu)(chu)口(kou)，在(zai)單泵(beng)啟動(dong)和非全(quan)數設(she)計工(gong)(gong)作(zuo)(zuo)(zuo)(zuo)泵(beng)工(gong)(gong)作(zuo)(zuo)(zuo)(zuo)時(shi)(shi)，多(duo)工(gong)(gong)作(zuo)(zuo)(zuo)(zuo)泵(beng)起限(xian)(xian)制(zhi)(zhi)流(liu)(liu)(liu)量(liang)(liang)作(zuo)(zuo)(zuo)(zuo)用(yong)，使泵(beng)在(zai)較高效率狀態下工(gong)(gong)作(zuo)(zuo)(zuo)(zuo)；防(fang)止(zhi)電動(dong)機(ji)(ji)(ji)愛水(shui)(shui)泵(beng)低揚程(cheng)、大流(liu)(liu)(liu)量(liang)(liang)、低效率時(shi)(shi)，發生過(guo)載(zai)現象(xiang)(xiang)；防(fang)止(zhi)超額定(ding)(ding)(ding)電流(liu)(liu)(liu)燒(shao)電機(ji)(ji)(ji)現象(xiang)(xiang)的(de)(de)發生，同時(shi)(shi)起到一定(ding)(ding)(ding)的(de)(de)節(jie)能(neng)效果。其限(xian)(xian)流(liu)(liu)(liu)原理為(wei)：依(yi)據(ju)水(shui)(shui)泵(beng)的(de)(de)設(she)計工(gong)(gong)況(kuang)揚程(cheng)，導閥(fa)(fa)自動(dong)檢(jian)測并控(kong)(kong)制(zhi)(zhi)水(shui)(shui)泵(beng)的(de)(de)實際工(gong)(gong)作(zuo)(zuo)(zuo)(zuo)揚程(cheng)，以(yi)限(xian)(xian)制(zhi)(zhi)水(shui)(shui)泵(beng)的(de)(de)工(gong)(gong)作(zuo)(zuo)(zuo)(zuo)流(liu)(liu)(liu)量(liang)(liang)，限(xian)(xian)制(zhi)(zhi)電機(ji)(ji)(ji)的(de)(de)負載(zai)。該閥(fa)(fa)設(she)定(ding)(ding)(ding)一個控(kong)(kong)制(zhi)(zhi)工(gong)(gong)作(zuo)(zuo)(zuo)(zuo)氣(qi)揚程(cheng)，當(dang)(dang)水(shui)(shui)泵(beng)工(gong)(gong)作(zuo)(zuo)(zuo)(zuo)揚程(cheng)低于(yu)(yu)控(kong)(kong)制(zhi)(zhi)揚程(cheng)時(shi)(shi)閥(fa)(fa)門(men)做(zuo)關(guan)閥(fa)(fa)動(dong)作(zuo)(zuo)(zuo)(zuo)，使實際工(gong)(gong)作(zuo)(zuo)(zuo)(zuo)揚程(cheng)加大；當(dang)(dang)水(shui)(shui)泵(beng)工(gong)(gong)作(zuo)(zuo)(zuo)(zuo)揚程(cheng)大于(yu)(yu)設(she)定(ding)(ding)(ding)揚程(cheng)時(shi)(shi)閥(fa)(fa)門(men)全(quan)開，閥(fa)(fa)門(men)阻力極(ji)小。控(kong)(kong)制(zhi)(zhi)氣(qi)揚程(cheng)的(de)(de)設(she)定(ding)(ding)(ding)可以(yi)按(an)電機(ji)(ji)(ji)額定(ding)(ding)(ding)電流(liu)(liu)(liu)設(she)定(ding)(ding)(ding)，也可以(yi)按(an)高效率工(gong)(gong)況(kuang)設(she)定(ding)(ding)(ding)，該閥(fa)(fa)門(men)工(gong)(gong)作(zuo)(zuo)(zuo)(zuo)揚程(cheng)設(she)定(ding)(ding)(ding)值可調，一般出(chu)(chu)廠設(she)定(ding)(ding)(ding)值為(wei)設(she)計工(gong)(gong)況(kuang)揚程(cheng)。二.止(zhi)回(hui)(hui)功(gong)能(neng).該閥(fa)(fa)的(de)(de)止(zhi)回(hui)(hui)功(gong)能(neng)完(wan)全(quan)等同于(yu)(yu)微阻緩閉(bi)止(zhi)回(hui)(hui)閥(fa)(fa)，且無關(guan)閉(bi)噪(zao)聲，零回(hui)(hui)流(liu)(liu)(liu)。此(ci)閥(fa)(fa)主要用(yong)于(yu)(yu)多(duo)泵(beng)并聯(lian)使用(yong)時(shi)(shi)安裝與水(shui)(shui)泵(beng)壓出(chu)(chu)口(kou)，起限(xian)(xian)制(zhi)(zhi)水(shui)(shui)泵(beng)工(gong)(gong)作(zuo)(zuo)(zuo)(zuo)流(liu)(liu)(liu)量(liang)(liang)，防(fang)止(zhi)停泵(beng)回(hui)(hui)流(liu)(liu)(liu)作(zuo)(zuo)(zuo)(zuo)用(yong)。該閥(fa)(fa)采用(yong)導閥(fa)(fa)-主閥(fa)(fa)構(gou)造(zao)，結構(gou)緊湊，重量(liang)(liang)較輕。
