意大利原產ATOS減壓閥注意事項

 ATOS減(jian)壓(ya)(ya)閥(fa)(fa)(fa)(fa)按(an)結構形(xing)式(shi)(shi)(shi)可分(fen)為薄膜式(shi)(shi)(shi)、彈(dan)(dan)簧薄膜式(shi)(shi)(shi)、活(huo)塞(sai)式(shi)(shi)(shi)、杠桿式(shi)(shi)(shi)和(he)(he)波(bo)紋管式(shi)(shi)(shi)；按(an)閥(fa)(fa)(fa)(fa)座數(shu)目可人(ren)為單座式(shi)(shi)(shi)和(he)(he)雙座式(shi)(shi)(shi)；按(an)閥(fa)(fa)(fa)(fa)瓣的(de)(de)位置不(bu)同可分(fen)為正作用(yong)式(shi)(shi)(shi)和(he)(he)反作用(yong)式(shi)(shi)(shi)。先(xian)(xian)(xian)導式(shi)(shi)(shi)減(jian)壓(ya)(ya)閥(fa)(fa)(fa)(fa)當減(jian)壓(ya)(ya)閥(fa)(fa)(fa)(fa)的(de)(de)輸(shu)(shu)出(chu)壓(ya)(ya)力較(jiao)(jiao)高或通徑(jing)較(jiao)(jiao)大時(shi)，用(yong)調(diao)壓(ya)(ya)彈(dan)(dan)簧直(zhi)接調(diao)壓(ya)(ya)，則彈(dan)(dan)簧剛度必然(ran)過大，流量(liang)變化(hua)時(shi)，輸(shu)(shu)出(chu)壓(ya)(ya)力波(bo)動(dong)(dong)較(jiao)(jiao)大，閥(fa)(fa)(fa)(fa)的(de)(de)結構尺寸也(ye)將增大。為了克服這些缺點，可采(cai)用(yong)先(xian)(xian)(xian)導式(shi)(shi)(shi)減(jian)壓(ya)(ya)閥(fa)(fa)(fa)(fa)。先(xian)(xian)(xian)導式(shi)(shi)(shi)減(jian)壓(ya)(ya)閥(fa)(fa)(fa)(fa)的(de)(de)工(gong)作原理與(yu)直(zhi)動(dong)(dong)式(shi)(shi)(shi)的(de)(de)基本相(xiang)同。先(xian)(xian)(xian)導式(shi)(shi)(shi)減(jian)壓(ya)(ya)閥(fa)(fa)(fa)(fa)所用(yong)的(de)(de)調(diao)壓(ya)(ya)氣體，是由小(xiao)(xiao)型的(de)(de)直(zhi)動(dong)(dong)式(shi)(shi)(shi)減(jian)壓(ya)(ya)閥(fa)(fa)(fa)(fa)供(gong)給的(de)(de)。若把小(xiao)(xiao)型直(zhi)動(dong)(dong)式(shi)(shi)(shi)減(jian)壓(ya)(ya)閥(fa)(fa)(fa)(fa)裝在(zai)閥(fa)(fa)(fa)(fa)體內部，則稱(cheng)為內部先(xian)(xian)(xian)導式(shi)(shi)(shi)減(jian)壓(ya)(ya)閥(fa)(fa)(fa)(fa)；若將小(xiao)(xiao)型直(zhi)動(dong)(dong)式(shi)(shi)(shi)減(jian)壓(ya)(ya)閥(fa)(fa)(fa)(fa)裝在(zai)主閥(fa)(fa)(fa)(fa)體外(wai)部，則稱(cheng)為外(wai)部先(xian)(xian)(xian)導式(shi)(shi)(shi)減(jian)壓(ya)(ya)閥(fa)(fa)(fa)(fa)。

ATOS減壓閥性能：

(1)調壓(ya)范(fan)圍：它是指減壓(ya)閥輸出(chu)壓(ya)力P2的(de)可調范(fan)圍，在此范(fan)圍內(nei)要(yao)求(qiu)達到規定的(de)精度。調壓(ya)范(fan)圍主(zhu)要(yao)與調壓(ya)彈簧的(de)剛度有關(guan)。

(2)壓(ya)力(li)特性(xing)：它是指(zhi)流量g為定(ding)值(zhi)時，因(yin)輸(shu)入壓(ya)力(li)波(bo)動而(er)引(yin)起輸(shu)出壓(ya)力(li)波(bo)動的特性(xing)。輸(shu)出壓(ya)力(li)波(bo)動越小，減壓(ya)閥的特性(xing)越好。輸(shu)出壓(ya)力(li)必(bi)須低于輸(shu)入壓(ya)力(li)—定(ding)值(zhi)才基本上不隨輸(shu)入壓(ya)力(li)變化(hua)而(er)變化(hua)。

(3)流(liu)量(liang)特性：它是指輸(shu)(shu)(shu)入(ru)壓(ya)(ya)力—定(ding)時，輸(shu)(shu)(shu)出(chu)(chu)壓(ya)(ya)力隨輸(shu)(shu)(shu)出(chu)(chu)流(liu)量(liang)g的(de)變(bian)化(hua)(hua)而變(bian)化(hua)(hua)的(de)持性。當(dang)流(liu)量(liang)g發生變(bian)化(hua)(hua)時，輸(shu)(shu)(shu)出(chu)(chu)壓(ya)(ya)力的(de)變(bian)化(hua)(hua)越(yue)(yue)小(xiao)越(yue)(yue)好(hao)。一般輸(shu)(shu)(shu)出(chu)(chu)壓(ya)(ya)力越(yue)(yue)低，它隨輸(shu)(shu)(shu)出(chu)(chu)流(liu)量(liang)的(de)變(bian)化(hua)(hua)波動就越(yue)(yue)小(xiao)。
