上海閥(fa)盛閥(fa)門制造有限公(gong)司主(zhu)要生產氨用(yong)(yong)(yong)(yong)(yong)球閥(fa)，可提供氨用(yong)(yong)(yong)(yong)(yong)球閥(fa)價格(ge)，氨用(yong)(yong)(yong)(yong)(yong)球閥(fa)說明書，氨用(yong)(yong)(yong)(yong)(yong)球閥(fa)實(shi)物圖(tu)，氨用(yong)(yong)(yong)(yong)(yong)球閥(fa)結(jie)構圖(tu)，氨用(yong)(yong)(yong)(yong)(yong)球閥(fa)外形尺寸，氨用(yong)(yong)(yong)(yong)(yong)球閥(fa)執行標準，氨用(yong)(yong)(yong)(yong)(yong)球閥(fa)工(gong)作(zuo)原(yuan)理(li)，氨用(yong)(yong)(yong)(yong)(yong)球閥(fa)作(zuo)用(yong)(yong)(yong)(yong)(yong)特(te)點。

氨氣球閥的外觀及工作原(yuan)理: 

  氨(an)用(yong)閥門的(de)(de)(de)高壓(ya)(ya)(ya)(ya)(ya)腔(qiang)與鋼瓶連接，低壓(ya)(ya)(ya)(ya)(ya)腔(qiang)為氣體(ti)出口，并(bing)(bing)通(tong)往(wang)使(shi)(shi)用(yong)系統。高壓(ya)(ya)(ya)(ya)(ya)表的(de)(de)(de)示值為鋼瓶內貯存氣體(ti)的(de)(de)(de)壓(ya)(ya)(ya)(ya)(ya)力(li)(li)(li)。低壓(ya)(ya)(ya)(ya)(ya)表的(de)(de)(de)出口壓(ya)(ya)(ya)(ya)(ya)力(li)(li)(li)可由(you)調節螺(luo)(luo)桿控制。 使(shi)(shi)用(yong)時(shi)(shi)先打開(kai)鋼瓶總開(kai)關(guan)，然后順時(shi)(shi)針轉動低壓(ya)(ya)(ya)(ya)(ya)表壓(ya)(ya)(ya)(ya)(ya)力(li)(li)(li)調節螺(luo)(luo)桿，使(shi)(shi)其壓(ya)(ya)(ya)(ya)(ya)縮主彈(dan)簧并(bing)(bing)傳動薄膜、彈(dan)簧墊塊和(he)頂桿而將(jiang)活(huo)門打開(kai)。這樣進(jin)口的(de)(de)(de)高壓(ya)(ya)(ya)(ya)(ya)氣體(ti)由(you)高壓(ya)(ya)(ya)(ya)(ya)室(shi)經節流減壓(ya)(ya)(ya)(ya)(ya)后進(jin)入低壓(ya)(ya)(ya)(ya)(ya)室(shi)，并(bing)(bing)經出口通(tong)往(wang)工作系統。轉動調節螺(luo)(luo)桿，改變(bian)活(huo)門開(kai)啟(qi)的(de)(de)(de)高度(du)，從而調節高壓(ya)(ya)(ya)(ya)(ya)氣體(ti)的(de)(de)(de)通(tong)過量并(bing)(bing)達到所需的(de)(de)(de)壓(ya)(ya)(ya)(ya)(ya)力(li)(li)(li)值。 氨(an)氣球閥都裝(zhuang)有安(an)全(quan)閥。它是保護氨(an)氣減壓(ya)(ya)(ya)(ya)(ya)閥并(bing)(bing)使(shi)(shi)之安(an)全(quan)使(shi)(shi)用(yong)的(de)(de)(de)裝(zhuang)置(zhi)，也是氨(an)氣球閥出現故障的(de)(de)(de)信號裝(zhuang)置(zhi)。如果由(you)于活(huo)門墊、活(huo)門損壞(huai)或由(you)于其它原(yuan)因，導致出口壓(ya)(ya)(ya)(ya)(ya)力(li)(li)(li)自(zi)行(xing)上升并(bing)(bing)超過一定許(xu)可值時(shi)(shi)，安(an)全(quan)閥會自(zi)動打開(kai)排氣。
