限流止回閥功能和作用：

一.限(xian)流功能(neng)(neng)該閥(fa)(fa)(fa)安(an)裝(zhuang)于水(shui)(shui)泵(beng)(beng)(beng)(beng)出(chu)口，在單泵(beng)(beng)(beng)(beng)啟動(dong)和非全數(shu)設(she)(she)(she)(she)(she)計工(gong)(gong)(gong)作(zuo)泵(beng)(beng)(beng)(beng)工(gong)(gong)(gong)作(zuo)時，多(duo)工(gong)(gong)(gong)作(zuo)泵(beng)(beng)(beng)(beng)起限(xian)制(zhi)(zhi)(zhi)流量作(zuo)用(yong)(yong)，使泵(beng)(beng)(beng)(beng)在較高(gao)效(xiao)率(lv)狀態下工(gong)(gong)(gong)作(zuo)；防(fang)止(zhi)(zhi)電動(dong)機愛水(shui)(shui)泵(beng)(beng)(beng)(beng)低(di)揚(yang)(yang)(yang)程(cheng)(cheng)(cheng)、大(da)流量、低(di)效(xiao)率(lv)時，發生過載(zai)現象(xiang)；防(fang)止(zhi)(zhi)超額定(ding)(ding)(ding)電流燒電機現象(xiang)的發生，同(tong)時起到一定(ding)(ding)(ding)的節能(neng)(neng)效(xiao)果(guo)。其限(xian)流原理(li)為：依據水(shui)(shui)泵(beng)(beng)(beng)(beng)的設(she)(she)(she)(she)(she)計工(gong)(gong)(gong)況揚(yang)(yang)(yang)程(cheng)(cheng)(cheng)，導閥(fa)(fa)(fa)自動(dong)檢(jian)測(ce)并(bing)控(kong)(kong)制(zhi)(zhi)(zhi)水(shui)(shui)泵(beng)(beng)(beng)(beng)的實(shi)際工(gong)(gong)(gong)作(zuo)揚(yang)(yang)(yang)程(cheng)(cheng)(cheng)，以限(xian)制(zhi)(zhi)(zhi)水(shui)(shui)泵(beng)(beng)(beng)(beng)的工(gong)(gong)(gong)作(zuo)流量，限(xian)制(zhi)(zhi)(zhi)電機的負(fu)載(zai)。該閥(fa)(fa)(fa)設(she)(she)(she)(she)(she)定(ding)(ding)(ding)一個控(kong)(kong)制(zhi)(zhi)(zhi)工(gong)(gong)(gong)作(zuo)氣揚(yang)(yang)(yang)程(cheng)(cheng)(cheng)，當(dang)水(shui)(shui)泵(beng)(beng)(beng)(beng)工(gong)(gong)(gong)作(zuo)揚(yang)(yang)(yang)程(cheng)(cheng)(cheng)低(di)于控(kong)(kong)制(zhi)(zhi)(zhi)揚(yang)(yang)(yang)程(cheng)(cheng)(cheng)時閥(fa)(fa)(fa)門做關閥(fa)(fa)(fa)動(dong)作(zuo)，使實(shi)際工(gong)(gong)(gong)作(zuo)揚(yang)(yang)(yang)程(cheng)(cheng)(cheng)加大(da)；當(dang)水(shui)(shui)泵(beng)(beng)(beng)(beng)工(gong)(gong)(gong)作(zuo)揚(yang)(yang)(yang)程(cheng)(cheng)(cheng)大(da)于設(she)(she)(she)(she)(she)定(ding)(ding)(ding)揚(yang)(yang)(yang)程(cheng)(cheng)(cheng)時閥(fa)(fa)(fa)門全開，閥(fa)(fa)(fa)門阻力(li)極小。控(kong)(kong)制(zhi)(zhi)(zhi)氣揚(yang)(yang)(yang)程(cheng)(cheng)(cheng)的設(she)(she)(she)(she)(she)定(ding)(ding)(ding)可(ke)以按電機額定(ding)(ding)(ding)電流設(she)(she)(she)(she)(she)定(ding)(ding)(ding)，也可(ke)以按高(gao)效(xiao)率(lv)工(gong)(gong)(gong)況設(she)(she)(she)(she)(she)定(ding)(ding)(ding)，該閥(fa)(fa)(fa)門工(gong)(gong)(gong)作(zuo)揚(yang)(yang)(yang)程(cheng)(cheng)(cheng)設(she)(she)(she)(she)(she)定(ding)(ding)(ding)值可(ke)調，一般出(chu)廠設(she)(she)(she)(she)(she)定(ding)(ding)(ding)值為設(she)(she)(she)(she)(she)計工(gong)(gong)(gong)況揚(yang)(yang)(yang)程(cheng)(cheng)(cheng)。二.止(zhi)(zhi)回(hui)功能(neng)(neng).該閥(fa)(fa)(fa)的止(zhi)(zhi)回(hui)功能(neng)(neng)完全等同(tong)于微(wei)阻緩閉(bi)(bi)止(zhi)(zhi)回(hui)閥(fa)(fa)(fa)，且無(wu)關閉(bi)(bi)噪聲，零回(hui)流。此閥(fa)(fa)(fa)主要用(yong)(yong)于多(duo)泵(beng)(beng)(beng)(beng)并(bing)聯使用(yong)(yong)時安(an)裝(zhuang)與水(shui)(shui)泵(beng)(beng)(beng)(beng)壓出(chu)口，起限(xian)制(zhi)(zhi)(zhi)水(shui)(shui)泵(beng)(beng)(beng)(beng)工(gong)(gong)(gong)作(zuo)流量，防(fang)止(zhi)(zhi)停泵(beng)(beng)(beng)(beng)回(hui)流作(zuo)用(yong)(yong)。該閥(fa)(fa)(fa)采用(yong)(yong)導閥(fa)(fa)(fa)-主閥(fa)(fa)(fa)構造(zao)，結構緊湊，重量較輕。
