限流止回(hui)閥(fa)功能和作(zuo)用：

一(yi).限(xian)流(liu)功(gong)能該(gai)(gai)閥(fa)(fa)安裝(zhuang)于(yu)(yu)(yu)水(shui)(shui)泵(beng)(beng)出口，在(zai)單泵(beng)(beng)啟(qi)動(dong)和非(fei)全數設(she)(she)計工(gong)(gong)(gong)(gong)作(zuo)(zuo)泵(beng)(beng)工(gong)(gong)(gong)(gong)作(zuo)(zuo)時，多工(gong)(gong)(gong)(gong)作(zuo)(zuo)泵(beng)(beng)起限(xian)制(zhi)流(liu)量(liang)(liang)作(zuo)(zuo)用(yong)，使(shi)(shi)泵(beng)(beng)在(zai)較高(gao)(gao)效率(lv)狀(zhuang)態下工(gong)(gong)(gong)(gong)作(zuo)(zuo)；防(fang)止(zhi)(zhi)電(dian)動(dong)機愛(ai)水(shui)(shui)泵(beng)(beng)低揚(yang)(yang)(yang)程(cheng)、大流(liu)量(liang)(liang)、低效率(lv)時，發生(sheng)過載現(xian)象；防(fang)止(zhi)(zhi)超(chao)額(e)定(ding)(ding)電(dian)流(liu)燒電(dian)機現(xian)象的(de)(de)(de)(de)發生(sheng)，同(tong)時起到(dao)一(yi)定(ding)(ding)的(de)(de)(de)(de)節能效果。其限(xian)流(liu)原理為：依據(ju)水(shui)(shui)泵(beng)(beng)的(de)(de)(de)(de)設(she)(she)計工(gong)(gong)(gong)(gong)況揚(yang)(yang)(yang)程(cheng)，導(dao)閥(fa)(fa)自(zi)動(dong)檢測并(bing)控(kong)制(zhi)水(shui)(shui)泵(beng)(beng)的(de)(de)(de)(de)實際(ji)工(gong)(gong)(gong)(gong)作(zuo)(zuo)揚(yang)(yang)(yang)程(cheng)，以(yi)限(xian)制(zhi)水(shui)(shui)泵(beng)(beng)的(de)(de)(de)(de)工(gong)(gong)(gong)(gong)作(zuo)(zuo)流(liu)量(liang)(liang)，限(xian)制(zhi)電(dian)機的(de)(de)(de)(de)負(fu)載。該(gai)(gai)閥(fa)(fa)設(she)(she)定(ding)(ding)一(yi)個控(kong)制(zhi)工(gong)(gong)(gong)(gong)作(zuo)(zuo)氣揚(yang)(yang)(yang)程(cheng)，當水(shui)(shui)泵(beng)(beng)工(gong)(gong)(gong)(gong)作(zuo)(zuo)揚(yang)(yang)(yang)程(cheng)低于(yu)(yu)(yu)控(kong)制(zhi)揚(yang)(yang)(yang)程(cheng)時閥(fa)(fa)門(men)做關(guan)(guan)閥(fa)(fa)動(dong)作(zuo)(zuo)，使(shi)(shi)實際(ji)工(gong)(gong)(gong)(gong)作(zuo)(zuo)揚(yang)(yang)(yang)程(cheng)加大；當水(shui)(shui)泵(beng)(beng)工(gong)(gong)(gong)(gong)作(zuo)(zuo)揚(yang)(yang)(yang)程(cheng)大于(yu)(yu)(yu)設(she)(she)定(ding)(ding)揚(yang)(yang)(yang)程(cheng)時閥(fa)(fa)門(men)全開(kai)，閥(fa)(fa)門(men)阻力極小。控(kong)制(zhi)氣揚(yang)(yang)(yang)程(cheng)的(de)(de)(de)(de)設(she)(she)定(ding)(ding)可以(yi)按(an)電(dian)機額(e)定(ding)(ding)電(dian)流(liu)設(she)(she)定(ding)(ding)，也可以(yi)按(an)高(gao)(gao)效率(lv)工(gong)(gong)(gong)(gong)況設(she)(she)定(ding)(ding)，該(gai)(gai)閥(fa)(fa)門(men)工(gong)(gong)(gong)(gong)作(zuo)(zuo)揚(yang)(yang)(yang)程(cheng)設(she)(she)定(ding)(ding)值可調，一(yi)般(ban)出廠(chang)設(she)(she)定(ding)(ding)值為設(she)(she)計工(gong)(gong)(gong)(gong)況揚(yang)(yang)(yang)程(cheng)。二.止(zhi)(zhi)回(hui)功(gong)能.該(gai)(gai)閥(fa)(fa)的(de)(de)(de)(de)止(zhi)(zhi)回(hui)功(gong)能完全等(deng)同(tong)于(yu)(yu)(yu)微阻緩閉止(zhi)(zhi)回(hui)閥(fa)(fa)，且無關(guan)(guan)閉噪聲，零回(hui)流(liu)。此閥(fa)(fa)主(zhu)要用(yong)于(yu)(yu)(yu)多泵(beng)(beng)并(bing)聯(lian)使(shi)(shi)用(yong)時安裝(zhuang)與水(shui)(shui)泵(beng)(beng)壓(ya)出口，起限(xian)制(zhi)水(shui)(shui)泵(beng)(beng)工(gong)(gong)(gong)(gong)作(zuo)(zuo)流(liu)量(liang)(liang)，防(fang)止(zhi)(zhi)停泵(beng)(beng)回(hui)流(liu)作(zuo)(zuo)用(yong)。該(gai)(gai)閥(fa)(fa)采用(yong)導(dao)閥(fa)(fa)-主(zhu)閥(fa)(fa)構造，結構緊湊，重量(liang)(liang)較輕。
