限(xian)流止回閥功能和作用：

一.限(xian)(xian)流(liu)(liu)(liu)功(gong)(gong)能(neng)(neng)該(gai)(gai)閥(fa)安(an)裝于水泵(beng)(beng)(beng)(beng)(beng)出口，在單泵(beng)(beng)(beng)(beng)(beng)啟(qi)動(dong)(dong)和(he)非全數設(she)計工(gong)(gong)(gong)(gong)(gong)作泵(beng)(beng)(beng)(beng)(beng)工(gong)(gong)(gong)(gong)(gong)作時(shi)，多工(gong)(gong)(gong)(gong)(gong)作泵(beng)(beng)(beng)(beng)(beng)起限(xian)(xian)制(zhi)(zhi)(zhi)流(liu)(liu)(liu)量作用，使泵(beng)(beng)(beng)(beng)(beng)在較高效率(lv)狀態下(xia)工(gong)(gong)(gong)(gong)(gong)作；防(fang)(fang)止(zhi)電(dian)(dian)動(dong)(dong)機(ji)愛水泵(beng)(beng)(beng)(beng)(beng)低(di)揚(yang)程(cheng)(cheng)(cheng)(cheng)、大流(liu)(liu)(liu)量、低(di)效率(lv)時(shi)，發(fa)生過載現象(xiang)；防(fang)(fang)止(zhi)超額定(ding)電(dian)(dian)流(liu)(liu)(liu)燒電(dian)(dian)機(ji)現象(xiang)的(de)發(fa)生，同時(shi)起到(dao)一定(ding)的(de)節能(neng)(neng)效果(guo)。其限(xian)(xian)流(liu)(liu)(liu)原理為：依(yi)據(ju)水泵(beng)(beng)(beng)(beng)(beng)的(de)設(she)計工(gong)(gong)(gong)(gong)(gong)況(kuang)揚(yang)程(cheng)(cheng)(cheng)(cheng)，導閥(fa)自動(dong)(dong)檢測并(bing)(bing)控(kong)制(zhi)(zhi)(zhi)水泵(beng)(beng)(beng)(beng)(beng)的(de)實(shi)際工(gong)(gong)(gong)(gong)(gong)作揚(yang)程(cheng)(cheng)(cheng)(cheng)，以限(xian)(xian)制(zhi)(zhi)(zhi)水泵(beng)(beng)(beng)(beng)(beng)的(de)工(gong)(gong)(gong)(gong)(gong)作流(liu)(liu)(liu)量，限(xian)(xian)制(zhi)(zhi)(zhi)電(dian)(dian)機(ji)的(de)負載。該(gai)(gai)閥(fa)設(she)定(ding)一個(ge)控(kong)制(zhi)(zhi)(zhi)工(gong)(gong)(gong)(gong)(gong)作氣揚(yang)程(cheng)(cheng)(cheng)(cheng)，當(dang)水泵(beng)(beng)(beng)(beng)(beng)工(gong)(gong)(gong)(gong)(gong)作揚(yang)程(cheng)(cheng)(cheng)(cheng)低(di)于控(kong)制(zhi)(zhi)(zhi)揚(yang)程(cheng)(cheng)(cheng)(cheng)時(shi)閥(fa)門(men)(men)做關(guan)閥(fa)動(dong)(dong)作，使實(shi)際工(gong)(gong)(gong)(gong)(gong)作揚(yang)程(cheng)(cheng)(cheng)(cheng)加(jia)大；當(dang)水泵(beng)(beng)(beng)(beng)(beng)工(gong)(gong)(gong)(gong)(gong)作揚(yang)程(cheng)(cheng)(cheng)(cheng)大于設(she)定(ding)揚(yang)程(cheng)(cheng)(cheng)(cheng)時(shi)閥(fa)門(men)(men)全開，閥(fa)門(men)(men)阻力極小(xiao)。控(kong)制(zhi)(zhi)(zhi)氣揚(yang)程(cheng)(cheng)(cheng)(cheng)的(de)設(she)定(ding)可以按(an)電(dian)(dian)機(ji)額定(ding)電(dian)(dian)流(liu)(liu)(liu)設(she)定(ding)，也可以按(an)高效率(lv)工(gong)(gong)(gong)(gong)(gong)況(kuang)設(she)定(ding)，該(gai)(gai)閥(fa)門(men)(men)工(gong)(gong)(gong)(gong)(gong)作揚(yang)程(cheng)(cheng)(cheng)(cheng)設(she)定(ding)值(zhi)可調(diao)，一般出廠設(she)定(ding)值(zhi)為設(she)計工(gong)(gong)(gong)(gong)(gong)況(kuang)揚(yang)程(cheng)(cheng)(cheng)(cheng)。二.止(zhi)回功(gong)(gong)能(neng)(neng).該(gai)(gai)閥(fa)的(de)止(zhi)回功(gong)(gong)能(neng)(neng)完全等同于微阻緩閉止(zhi)回閥(fa)，且無關(guan)閉噪聲(sheng)，零回流(liu)(liu)(liu)。此閥(fa)主(zhu)要用于多泵(beng)(beng)(beng)(beng)(beng)并(bing)(bing)聯使用時(shi)安(an)裝與水泵(beng)(beng)(beng)(beng)(beng)壓出口，起限(xian)(xian)制(zhi)(zhi)(zhi)水泵(beng)(beng)(beng)(beng)(beng)工(gong)(gong)(gong)(gong)(gong)作流(liu)(liu)(liu)量，防(fang)(fang)止(zhi)停泵(beng)(beng)(beng)(beng)(beng)回流(liu)(liu)(liu)作用。該(gai)(gai)閥(fa)采用導閥(fa)-主(zhu)閥(fa)構造，結構緊湊，重量較輕。
