上海閥(fa)(fa)(fa)(fa)(fa)盛(sheng)閥(fa)(fa)(fa)(fa)(fa)門制造(zao)有限公司(si)主要(yao)生產氨(an)(an)用(yong)(yong)(yong)(yong)球(qiu)閥(fa)(fa)(fa)(fa)(fa)，可提供氨(an)(an)用(yong)(yong)(yong)(yong)球(qiu)閥(fa)(fa)(fa)(fa)(fa)價(jia)格，氨(an)(an)用(yong)(yong)(yong)(yong)球(qiu)閥(fa)(fa)(fa)(fa)(fa)說明書，氨(an)(an)用(yong)(yong)(yong)(yong)球(qiu)閥(fa)(fa)(fa)(fa)(fa)實物圖(tu)，氨(an)(an)用(yong)(yong)(yong)(yong)球(qiu)閥(fa)(fa)(fa)(fa)(fa)結構圖(tu)，氨(an)(an)用(yong)(yong)(yong)(yong)球(qiu)閥(fa)(fa)(fa)(fa)(fa)外形尺寸，氨(an)(an)用(yong)(yong)(yong)(yong)球(qiu)閥(fa)(fa)(fa)(fa)(fa)執行(xing)標準，氨(an)(an)用(yong)(yong)(yong)(yong)球(qiu)閥(fa)(fa)(fa)(fa)(fa)工作(zuo)原理，氨(an)(an)用(yong)(yong)(yong)(yong)球(qiu)閥(fa)(fa)(fa)(fa)(fa)作(zuo)用(yong)(yong)(yong)(yong)特點。

氨氣球閥的外(wai)觀及工作原(yuan)理(li): 

  氨(an)(an)(an)用(yong)閥(fa)(fa)門(men)(men)的(de)(de)(de)高(gao)壓(ya)(ya)(ya)腔與鋼瓶(ping)連接，低(di)壓(ya)(ya)(ya)腔為(wei)氣(qi)(qi)體(ti)出口(kou)，并(bing)通往使(shi)(shi)用(yong)系統。高(gao)壓(ya)(ya)(ya)表的(de)(de)(de)示值為(wei)鋼瓶(ping)內貯存氣(qi)(qi)體(ti)的(de)(de)(de)壓(ya)(ya)(ya)力(li)(li)(li)。低(di)壓(ya)(ya)(ya)表的(de)(de)(de)出口(kou)壓(ya)(ya)(ya)力(li)(li)(li)可(ke)(ke)由(you)調(diao)節(jie)螺桿(gan)控(kong)制。 使(shi)(shi)用(yong)時(shi)(shi)先打(da)開(kai)鋼瓶(ping)總開(kai)關，然后順時(shi)(shi)針轉(zhuan)動(dong)低(di)壓(ya)(ya)(ya)表壓(ya)(ya)(ya)力(li)(li)(li)調(diao)節(jie)螺桿(gan)，使(shi)(shi)其壓(ya)(ya)(ya)縮主彈簧(huang)并(bing)傳動(dong)薄膜、彈簧(huang)墊塊和頂桿(gan)而將活(huo)(huo)門(men)(men)打(da)開(kai)。這(zhe)樣(yang)進口(kou)的(de)(de)(de)高(gao)壓(ya)(ya)(ya)氣(qi)(qi)體(ti)由(you)高(gao)壓(ya)(ya)(ya)室(shi)經節(jie)流減(jian)(jian)壓(ya)(ya)(ya)后進入(ru)低(di)壓(ya)(ya)(ya)室(shi)，并(bing)經出口(kou)通往工作系統。轉(zhuan)動(dong)調(diao)節(jie)螺桿(gan)，改(gai)變(bian)活(huo)(huo)門(men)(men)開(kai)啟的(de)(de)(de)高(gao)度，從而調(diao)節(jie)高(gao)壓(ya)(ya)(ya)氣(qi)(qi)體(ti)的(de)(de)(de)通過量并(bing)達到所需的(de)(de)(de)壓(ya)(ya)(ya)力(li)(li)(li)值。 氨(an)(an)(an)氣(qi)(qi)球(qiu)閥(fa)(fa)都裝有安(an)全(quan)(quan)閥(fa)(fa)。它(ta)是(shi)保護氨(an)(an)(an)氣(qi)(qi)減(jian)(jian)壓(ya)(ya)(ya)閥(fa)(fa)并(bing)使(shi)(shi)之安(an)全(quan)(quan)使(shi)(shi)用(yong)的(de)(de)(de)裝置(zhi)，也是(shi)氨(an)(an)(an)氣(qi)(qi)球(qiu)閥(fa)(fa)出現故障的(de)(de)(de)信號裝置(zhi)。如果由(you)于(yu)活(huo)(huo)門(men)(men)墊、活(huo)(huo)門(men)(men)損壞(huai)或(huo)由(you)于(yu)其它(ta)原因，導致出口(kou)壓(ya)(ya)(ya)力(li)(li)(li)自行上升(sheng)并(bing)超(chao)過一(yi)定(ding)許(xu)可(ke)(ke)值時(shi)(shi)，安(an)全(quan)(quan)閥(fa)(fa)會自動(dong)打(da)開(kai)排氣(qi)(qi)。
