日本SMC過濾減壓閥特性數據

減(jian)(jian)(jian)壓(ya)(ya)(ya)(ya)閥的(de)(de)(de)作用原理是靠閥內流(liu)道對水(shui)(shui)(shui)流(liu)的(de)(de)(de)局部阻力降低水(shui)(shui)(shui)壓(ya)(ya)(ya)(ya)，水(shui)(shui)(shui)壓(ya)(ya)(ya)(ya)降的(de)(de)(de)范圍由連接閥瓣的(de)(de)(de)薄膜或活(huo)塞兩(liang)側(ce)的(de)(de)(de)進出口(kou)水(shui)(shui)(shui)壓(ya)(ya)(ya)(ya)差自動(dong)調(diao)節。近年來(lai)又出現一(yi)些新型減(jian)(jian)(jian)壓(ya)(ya)(ya)(ya)閥，如定(ding)比式減(jian)(jian)(jian)壓(ya)(ya)(ya)(ya)閥。定(ding)比減(jian)(jian)(jian)壓(ya)(ya)(ya)(ya)原理是利用閥體(ti)中浮動(dong)活(huo)塞的(de)(de)(de)水(shui)(shui)(shui)壓(ya)(ya)(ya)(ya)比控(kong)制，進出口(kou)端減(jian)(jian)(jian)壓(ya)(ya)(ya)(ya)比與進出口(kou)側(ce)活(huo)塞面(mian)積比成反比。這種減(jian)(jian)(jian)壓(ya)(ya)(ya)(ya)閥工(gong)作平穩無(wu)振動(dong)；閥體(ti)內無(wu)彈簧(huang)，故無(wu)彈簧(huang)銹蝕、金屬疲勞(lao)失效之慮；密封性(xing)能良(liang)好(hao)不滲漏，因而既減(jian)(jian)(jian)動(dong)壓(ya)(ya)(ya)(ya)（水(shui)(shui)(shui)流(liu)動(dong)時(shi)(shi)）又減(jian)(jian)(jian)靜壓(ya)(ya)(ya)(ya)（流(liu)量為0時(shi)(shi)）；特別是在(zai)減(jian)(jian)(jian)壓(ya)(ya)(ya)(ya)的(de)(de)(de)同時(shi)(shi)不影(ying)響(xiang)水(shui)(shui)(shui)流(liu)量。

減(jian)壓(ya)(ya)(ya)(ya)(ya)閥，是一種(zhong)利用(yong)介(jie)質自身能量來(lai)調節與控制管路(lu)壓(ya)(ya)(ya)(ya)(ya)力的(de)(de)(de)智能型閥門。200X減(jian)壓(ya)(ya)(ya)(ya)(ya)閥用(yong)于生活給(gei)水、消防給(gei)水及其他工業(ye)給(gei)水系統，通過調節閥減(jian)壓(ya)(ya)(ya)(ya)(ya)導閥，即(ji)可調節主閥的(de)(de)(de)出(chu)口(kou)壓(ya)(ya)(ya)(ya)(ya)力。出(chu)口(kou)壓(ya)(ya)(ya)(ya)(ya)力不因進口(kou)壓(ya)(ya)(ya)(ya)(ya)力、進口(kou)流(liu)量的(de)(de)(de)變化而變化，安全(quan)(quan)可靠(kao)地將出(chu)口(kou)壓(ya)(ya)(ya)(ya)(ya)力維持(chi)在設定(ding)(ding)植(zhi)上，并可根(gen)據需要調節設定(ding)(ding)值達到(dao)減(jian)壓(ya)(ya)(ya)(ya)(ya)的(de)(de)(de)目(mu)的(de)(de)(de)。該(gai)閥減(jian)壓(ya)(ya)(ya)(ya)(ya)精(jing)確，性能穩定(ding)(ding)、安全(quan)(quan)可靠(kao)、安裝調節方便，使(shi)用(yong)壽命(ming)長。

水流通過減壓(ya)(ya)閥(fa)(fa)雖(sui)有很大的(de)(de)(de)(de)(de)水頭損失(shi)，但由(you)于減少(shao)了水的(de)(de)(de)(de)(de)浪(lang)費并使系統(tong)流量分布(bu)合(he)理、改善了系統(tong)布(bu)局與工(gong)況，因此總(zong)體(ti)上講仍是(shi)節能的(de)(de)(de)(de)(de)。減壓(ya)(ya)閥(fa)(fa)的(de)(de)(de)(de)(de)每一檔(dang)彈簧(huang)只在一定的(de)(de)(de)(de)(de)出口壓(ya)(ya)力范圍(wei)內適用(yong)(yong)，超出范圍(wei)應更(geng)換(huan)彈簧(huang)。在介(jie)(jie)質工(gong)作(zuo)溫(wen)度(du)比較高的(de)(de)(de)(de)(de)場(chang)合(he)，一般(ban)選用(yong)(yong)先(xian)導活塞式(shi)減壓(ya)(ya)閥(fa)(fa)或(huo)先(xian)導波(bo)紋管(guan)式(shi)減壓(ya)(ya)閥(fa)(fa)。介(jie)(jie)質為(wei)空氣或(huo)水（液(ye)體(ti)）的(de)(de)(de)(de)(de)場(chang)合(he)，一般(ban)宜選用(yong)(yong)直(zhi)接作(zuo)用(yong)(yong)薄(bo)膜(mo)式(shi)減壓(ya)(ya)閥(fa)(fa)或(huo)先(xian)導薄(bo)膜(mo)式(shi)減壓(ya)(ya)閥(fa)(fa)。介(jie)(jie)質為(wei)蒸(zheng)汽的(de)(de)(de)(de)(de)場(chang)合(he)，宜選用(yong)(yong)先(xian)導活塞式(shi)減壓(ya)(ya)閥(fa)(fa)或(huo)先(xian)導波(bo)紋管(guan)式(shi)減壓(ya)(ya)閥(fa)(fa)。為(wei)了操作(zuo)、調整和維修的(de)(de)(de)(de)(de)方(fang)便，減壓(ya)(ya)閥(fa)(fa)一般(ban)應安裝在水平管(guan)道上。

減壓閥(fa)為一直接作用式可(ke)調減壓閥(fa)，采用隔膜型(xing)水力(li)操作方式，可(ke)水平或(huo)(huo)垂直安(an)(an)裝(zhuang)于(yu)給水、消防系統或(huo)(huo)其他清(qing)水系統中。在一定流水范圍內可(ke)控制(zhi)該閥(fa)門出口壓力(li)為一相對(dui)固定值(zhi)。200P型(xing)為內螺紋連(lian)接減壓閥(fa)，具有體型(xing)小(xiao)巧(qiao)，易于(yu)安(an)(an)裝(zhuang)等特點，具附有內置(zhi)式濾網，可(ke)方便整(zheng)體安(an)(an)裝(zhuang)作業，避(bi)免雜物堵塞，使其更加安(an)(an)全(quan)可(ke)靠。

該閥主要配套(tao)在減溫裝置上，起到調(diao)節壓(ya)力的作用。減壓(ya)比一般用0.6較合適(shi)，選用DKJ-310電動(dong)執(zhi)行裝置，DN500閥選用DKJ-510電動(dong)執(zhi)行裝置較合適(shi)。
