產品概述：

LH45X微阻限流止回閥設(she)定(ding)個控制(zhi)工(gong)作(zuo)(zuo)(zuo)(zuo)(zuo)揚程(cheng)，當(dang)水泵(beng)(beng)工(gong)作(zuo)(zuo)(zuo)(zuo)(zuo)揚程(cheng)低(di)于控制(zhi)揚程(cheng)時閥(fa)(fa)(fa)門做(zuo)關閥(fa)(fa)(fa)動作(zuo)(zuo)(zuo)(zuo)(zuo)，使實際(ji)工(gong)作(zuo)(zuo)(zuo)(zuo)(zuo)揚程(cheng)加大(da)；當(dang)水泵(beng)(beng)工(gong)作(zuo)(zuo)(zuo)(zuo)(zuo)揚程(cheng)大(da)于設(she)定(ding)揚程(cheng)時閥(fa)(fa)(fa)門全開，閥(fa)(fa)(fa)門阻力極(ji)小。該(gai)閥(fa)(fa)(fa)安(an)裝于水泵(beng)(beng)出口，在(zai)單泵(beng)(beng)啟動和非全數設(she)計工(gong)作(zuo)(zuo)(zuo)(zuo)(zuo)數設(she)計工(gong)作(zuo)(zuo)(zuo)(zuo)(zuo)泵(beng)(beng)工(gong)作(zuo)(zuo)(zuo)(zuo)(zuo)時，對工(gong)作(zuo)(zuo)(zuo)(zuo)(zuo)泵(beng)(beng)起限制(zhi)流(liu)量(liang)作(zuo)(zuo)(zuo)(zuo)(zuo)用，使泵(beng)(beng)在(zai)較高效率(lv)狀態下工(gong)作(zuo)(zuo)(zuo)(zuo)(zuo)；防止電動機在(zai)水泵(beng)(beng)低(di)揚程(cheng)、大(da)流(liu)量(liang)、低(di)效率(lv)時發生過(guo)載現(xian)象；防止超額定(ding)電流(liu)燒電機現(xian)象的發生，起到顯著的節能效果。

功能和作用： 

1. 限流功能該閥安裝于水泵出口，在單泵啟動和非全數設計工作泵工作時，多工作泵起限制流量作用，使泵在較高效率狀態下工作  
2. 防止電(dian)動機受(shou)水泵低揚程(cheng)、大流量、低效(xiao)率(lv)時，發生過載現象；防止超額定電(dian)流燒電(dian)機現象的發生，同(tong)時起(qi)到定的節能效(xiao)果(guo)。

工作原理：

限(xian)流(liu)(liu)止(zhi)回(hui)(hui)(hui)閥(fa)(fa)(fa)(fa)依據水(shui)泵(beng)的(de)設計工(gong)(gong)況揚(yang)(yang)程(cheng)(cheng)(cheng)，導(dao)(dao)閥(fa)(fa)(fa)(fa)自動檢測(ce)并(bing)控(kong)(kong)制(zhi)水(shui)泵(beng)的(de)實際工(gong)(gong)作揚(yang)(yang)程(cheng)(cheng)(cheng)，以(yi)限(xian)制(zhi)水(shui)泵(beng)的(de)工(gong)(gong)作流(liu)(liu)量，限(xian)制(zhi)電機的(de)負載。該(gai)閥(fa)(fa)(fa)(fa)設定(ding)(ding)個控(kong)(kong)制(zhi)工(gong)(gong)作氣揚(yang)(yang)程(cheng)(cheng)(cheng)，當(dang)水(shui)泵(beng)工(gong)(gong)作揚(yang)(yang)程(cheng)(cheng)(cheng)低(di)于(yu)控(kong)(kong)制(zhi)揚(yang)(yang)程(cheng)(cheng)(cheng)時閥(fa)(fa)(fa)(fa)門做關(guan)閥(fa)(fa)(fa)(fa)動作，使實際工(gong)(gong)作揚(yang)(yang)程(cheng)(cheng)(cheng)加(jia)大(da)；限(xian)流(liu)(liu)止(zhi)回(hui)(hui)(hui)閥(fa)(fa)(fa)(fa)當(dang)水(shui)泵(beng)工(gong)(gong)作揚(yang)(yang)程(cheng)(cheng)(cheng)大(da)于(yu)設定(ding)(ding)揚(yang)(yang)程(cheng)(cheng)(cheng)時閥(fa)(fa)(fa)(fa)門全開，閥(fa)(fa)(fa)(fa)門阻力極小。控(kong)(kong)制(zhi)氣揚(yang)(yang)程(cheng)(cheng)(cheng)的(de)設定(ding)(ding)可(ke)(ke)以(yi)按電機額定(ding)(ding)電流(liu)(liu)設定(ding)(ding)，也可(ke)(ke)以(yi)按高(gao)效率工(gong)(gong)況設定(ding)(ding)，該(gai)閥(fa)(fa)(fa)(fa)門工(gong)(gong)作揚(yang)(yang)程(cheng)(cheng)(cheng)設定(ding)(ding)值(zhi)可(ke)(ke)調，般出廠設定(ding)(ding)值(zhi)為設計工(gong)(gong)況揚(yang)(yang)程(cheng)(cheng)(cheng)。限(xian)流(liu)(liu)止(zhi)回(hui)(hui)(hui)閥(fa)(fa)(fa)(fa)的(de)止(zhi)回(hui)(hui)(hui)功(gong)能*等同(tong)于(yu)微阻緩閉止(zhi)回(hui)(hui)(hui)閥(fa)(fa)(fa)(fa)，且無(wu)關(guan)閉噪聲，零(ling)回(hui)(hui)(hui)流(liu)(liu)。此閥(fa)(fa)(fa)(fa)主(zhu)要(yao)用于(yu)多(duo)泵(beng)并(bing)聯使用時安裝(zhuang)與(yu)水(shui)泵(beng)壓出口，起(qi)限(xian)制(zhi)水(shui)泵(beng)工(gong)(gong)作流(liu)(liu)量，防止(zhi)停泵(beng)回(hui)(hui)(hui)流(liu)(liu)作用。該(gai)閥(fa)(fa)(fa)(fa)采用導(dao)(dao)閥(fa)(fa)(fa)(fa)-主(zhu)閥(fa)(fa)(fa)(fa)構造，結構緊湊，重量較(jiao)輕。
