限流止回閥功(gong)能和作用：

一(yi)(yi).限流(liu)(liu)(liu)(liu)(liu)功能該閥安裝于(yu)水(shui)(shui)泵(beng)出(chu)口(kou)(kou)，在單泵(beng)啟動(dong)和非全數設(she)(she)(she)計(ji)工(gong)(gong)作(zuo)(zuo)(zuo)泵(beng)工(gong)(gong)作(zuo)(zuo)(zuo)時(shi)(shi)(shi)，多工(gong)(gong)作(zuo)(zuo)(zuo)泵(beng)起(qi)限制流(liu)(liu)(liu)(liu)(liu)量(liang)作(zuo)(zuo)(zuo)用(yong)(yong)，使泵(beng)在較(jiao)高效率(lv)狀態下工(gong)(gong)作(zuo)(zuo)(zuo)；防(fang)止(zhi)電(dian)動(dong)機(ji)愛水(shui)(shui)泵(beng)低(di)揚(yang)(yang)(yang)程、大流(liu)(liu)(liu)(liu)(liu)量(liang)、低(di)效率(lv)時(shi)(shi)(shi)，發(fa)生(sheng)過載現(xian)象(xiang)；防(fang)止(zhi)超(chao)額定(ding)(ding)(ding)(ding)電(dian)流(liu)(liu)(liu)(liu)(liu)燒電(dian)機(ji)現(xian)象(xiang)的(de)(de)發(fa)生(sheng)，同時(shi)(shi)(shi)起(qi)到一(yi)(yi)定(ding)(ding)(ding)(ding)的(de)(de)節能效果。其限流(liu)(liu)(liu)(liu)(liu)原理為(wei)：依據水(shui)(shui)泵(beng)的(de)(de)設(she)(she)(she)計(ji)工(gong)(gong)況揚(yang)(yang)(yang)程，導閥自(zi)動(dong)檢測并(bing)(bing)控制水(shui)(shui)泵(beng)的(de)(de)實際(ji)工(gong)(gong)作(zuo)(zuo)(zuo)揚(yang)(yang)(yang)程，以(yi)(yi)限制水(shui)(shui)泵(beng)的(de)(de)工(gong)(gong)作(zuo)(zuo)(zuo)流(liu)(liu)(liu)(liu)(liu)量(liang)，限制電(dian)機(ji)的(de)(de)負載。該閥設(she)(she)(she)定(ding)(ding)(ding)(ding)一(yi)(yi)個(ge)控制工(gong)(gong)作(zuo)(zuo)(zuo)氣揚(yang)(yang)(yang)程，當水(shui)(shui)泵(beng)工(gong)(gong)作(zuo)(zuo)(zuo)揚(yang)(yang)(yang)程低(di)于(yu)控制揚(yang)(yang)(yang)程時(shi)(shi)(shi)閥門做關閥動(dong)作(zuo)(zuo)(zuo)，使實際(ji)工(gong)(gong)作(zuo)(zuo)(zuo)揚(yang)(yang)(yang)程加大；當水(shui)(shui)泵(beng)工(gong)(gong)作(zuo)(zuo)(zuo)揚(yang)(yang)(yang)程大于(yu)設(she)(she)(she)定(ding)(ding)(ding)(ding)揚(yang)(yang)(yang)程時(shi)(shi)(shi)閥門全開(kai)，閥門阻力極小。控制氣揚(yang)(yang)(yang)程的(de)(de)設(she)(she)(she)定(ding)(ding)(ding)(ding)可(ke)以(yi)(yi)按電(dian)機(ji)額定(ding)(ding)(ding)(ding)電(dian)流(liu)(liu)(liu)(liu)(liu)設(she)(she)(she)定(ding)(ding)(ding)(ding)，也可(ke)以(yi)(yi)按高效率(lv)工(gong)(gong)況設(she)(she)(she)定(ding)(ding)(ding)(ding)，該閥門工(gong)(gong)作(zuo)(zuo)(zuo)揚(yang)(yang)(yang)程設(she)(she)(she)定(ding)(ding)(ding)(ding)值可(ke)調(diao)，一(yi)(yi)般出(chu)廠(chang)設(she)(she)(she)定(ding)(ding)(ding)(ding)值為(wei)設(she)(she)(she)計(ji)工(gong)(gong)況揚(yang)(yang)(yang)程。二.止(zhi)回(hui)(hui)功能.該閥的(de)(de)止(zhi)回(hui)(hui)功能完全等同于(yu)微(wei)阻緩(huan)閉(bi)止(zhi)回(hui)(hui)閥，且無關閉(bi)噪聲(sheng)，零回(hui)(hui)流(liu)(liu)(liu)(liu)(liu)。此閥主要用(yong)(yong)于(yu)多泵(beng)并(bing)(bing)聯使用(yong)(yong)時(shi)(shi)(shi)安裝與水(shui)(shui)泵(beng)壓出(chu)口(kou)(kou)，起(qi)限制水(shui)(shui)泵(beng)工(gong)(gong)作(zuo)(zuo)(zuo)流(liu)(liu)(liu)(liu)(liu)量(liang)，防(fang)止(zhi)停泵(beng)回(hui)(hui)流(liu)(liu)(liu)(liu)(liu)作(zuo)(zuo)(zuo)用(yong)(yong)。該閥采(cai)用(yong)(yong)導閥-主閥構造，結構緊湊，重量(liang)較(jiao)輕(qing)。
