上海閥(fa)(fa)盛閥(fa)(fa)門(men)制造有限公司主(zhu)要生產壓(ya)差旁通(tong)(tong)閥(fa)(fa)，可提供(gong)壓(ya)差旁通(tong)(tong)閥(fa)(fa)價格(ge)，壓(ya)差旁通(tong)(tong)閥(fa)(fa)說(shuo)明書，壓(ya)差旁通(tong)(tong)閥(fa)(fa)實物圖，壓(ya)差旁通(tong)(tong)閥(fa)(fa)結構(gou)圖，壓(ya)差旁通(tong)(tong)閥(fa)(fa)外形(xing)尺寸，壓(ya)差旁通(tong)(tong)閥(fa)(fa)執(zhi)行標準，壓(ya)差旁通(tong)(tong)閥(fa)(fa)工(gong)作(zuo)原理，壓(ya)差旁通(tong)(tong)閥(fa)(fa)作(zuo)用特點(dian)。

壓(ya)(ya)(ya)差(cha)(cha)旁通(tong)閥(fa)(fa)由主(zhu)(zhu)閥(fa)(fa)、壓(ya)(ya)(ya)差(cha)(cha)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)導(dao)(dao)閥(fa)(fa)、針閥(fa)(fa)、球閥(fa)(fa)、微形過濾器和壓(ya)(ya)(ya)力表(biao)組成水(shui)力控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)接(jie)管(guan)系統(tong)。通(tong)過專門設計的(de)導(dao)(dao)閥(fa)(fa)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)室，對壓(ya)(ya)(ya)力變化(hua)信號進(jin)(jin)行比較，輸出(chu)(chu)主(zhu)(zhu)閥(fa)(fa)開(kai)(kai)度(du)信號，控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)主(zhu)(zhu)閥(fa)(fa)開(kai)(kai)度(du)，從而控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)主(zhu)(zhu)閥(fa)(fa)的(de)進(jin)(jin)出(chu)(chu)口(kou)壓(ya)(ya)(ya)差(cha)(cha)在設定(ding)(ding)(ding)值上。其(qi)工作原理是，當主(zhu)(zhu)閥(fa)(fa)進(jin)(jin)出(chu)(chu)口(kou)間壓(ya)(ya)(ya)差(cha)(cha)變化(hua)時，接(jie)管(guan)A與(yu)接(jie)管(guan)B間壓(ya)(ya)(ya)差(cha)(cha)發生變化(hua)，此變導(dao)(dao)閥(fa)(fa)的(de)開(kai)(kai)度(du)。壓(ya)(ya)(ya)差(cha)(cha)大時導(dao)(dao)閥(fa)(fa)開(kai)(kai)度(du)大，控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)室通(tong)過C管(guan)的(de)下泄(xie)水(shui)量增大，主(zhu)(zhu)閥(fa)(fa)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)室壓(ya)(ya)(ya)力下降，主(zhu)(zhu)閥(fa)(fa)開(kai)(kai)度(du)增大，主(zhu)(zhu)閥(fa)(fa)進(jin)(jin)出(chu)(chu)口(kou)間壓(ya)(ya)(ya)差(cha)(cha)變小(xiao)。反之，若主(zhu)(zhu)閥(fa)(fa)進(jin)(jin)出(chu)(chu)口(kou)間壓(ya)(ya)(ya)差(cha)(cha)變小(xiao)，則(ze)導(dao)(dao)閥(fa)(fa)開(kai)(kai)度(du)變小(xiao)，主(zhu)(zhu)閥(fa)(fa)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)室壓(ya)(ya)(ya)力上升，推動主(zhu)(zhu)閥(fa)(fa)開(kai)(kai)度(du)減小(xiao)而使主(zhu)(zhu)閥(fa)(fa)壓(ya)(ya)(ya)差(cha)(cha)增大。這種(zhong)負反饋作用(yong)使主(zhu)(zhu)閥(fa)(fa)進(jin)(jin)出(chu)(chu)口(kou)間壓(ya)(ya)(ya)差(cha)(cha)穩(wen)定(ding)(ding)(ding)在社頂值上。設定(ding)(ding)(ding)針閥(fa)(fa)開(kai)(kai)度(du)和導(dao)(dao)閥(fa)(fa)彈簧壓(ya)(ya)(ya)力可設定(ding)(ding)(ding)主(zhu)(zhu)閥(fa)(fa)進(jin)(jin)出(chu)(chu)口(kou)間壓(ya)(ya)(ya)差(cha)(cha)。本產品利用(yong)水(shui)力自力控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)，不需要(yao)其(qi)它裝(zhuang)置和能源，保(bao)養簡便，廣泛(fan)用(yong)于(yu)高層建筑、生活區等供(gong)水(shui)管(guan)網系統(tong)及(ji)城市供(gong)水(shui)工程。
