上(shang)海(hai)閥盛閥門(men)制(zhi)造(zao)有(you)限公(gong)司主要生產流(liu)(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)控(kong)(kong)(kong)(kong)(kong)制(zhi)閥，可(ke)提供流(liu)(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)控(kong)(kong)(kong)(kong)(kong)制(zhi)閥價格，流(liu)(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)控(kong)(kong)(kong)(kong)(kong)制(zhi)閥說明書，流(liu)(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)控(kong)(kong)(kong)(kong)(kong)制(zhi)閥實物(wu)圖，流(liu)(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)控(kong)(kong)(kong)(kong)(kong)制(zhi)閥結構圖，流(liu)(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)控(kong)(kong)(kong)(kong)(kong)制(zhi)閥外形尺寸(cun)，流(liu)(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)控(kong)(kong)(kong)(kong)(kong)制(zhi)閥執行標準，流(liu)(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)控(kong)(kong)(kong)(kong)(kong)制(zhi)閥工作原理，流(liu)(liu)(liu)(liu)(liu)(liu)量(liang)(liang)(liang)(liang)控(kong)(kong)(kong)(kong)(kong)制(zhi)閥作用特點。

流(liu)量(liang)控制(zhi)(zhi)閥(fa)是(shi)一(yi)(yi)種(zhong)采用(yong)(yong)高精度(du)先導(dao)式(shi)方式(shi)控制(zhi)(zhi)流(liu)量(liang)多功能閥(fa)門。適(shi)用(yong)(yong)于配(pei)水(shui)管需控制(zhi)(zhi)流(liu)量(liang)和(he)壓(ya)(ya)(ya)力的管路中，保持預(yu)定流(liu)量(liang)不變，將(jiang)過(guo)大流(liu)量(liang)限(xian)制(zhi)(zhi)在一(yi)(yi)個預(yu)定值，并(bing)將(jiang)上游(you)高壓(ya)(ya)(ya)適(shi)當減壓(ya)(ya)(ya)，即使(shi)主閥(fa)上游(you)的壓(ya)(ya)(ya)力發生變化，也不會(hui)影響主閥(fa)下游(you)的流(liu)量(liang)。該閥(fa)一(yi)(yi)改常規節流(liu)閥(fa)使(shi)用(yong)(yong)孔板或純機(ji)械的減少能量(liang)在節流(liu)過(guo)程中的損(sun)失。如遇緊急情況400XA流(liu)量(liang)控制(zhi)(zhi)閥(fa)可以完全截止流(liu)量(liang)，避(bi)免損(sun)失。控制(zhi)(zhi)靈敏度(du)高，安全可靠，調試簡便，使(shi)用(yong)(yong)壽命長。廣泛適(shi)用(yong)(yong)于工(gong)業給(gei)水(shui)、高層建筑由水(shui)泵直接給(gei)水(shui)系(xi)統中，調節流(liu)。
