氨(an)氣球閥的外觀及工作(zuo)原理: 

  氨(an)用(yong)(yong)閥(fa)(fa)門(men)的(de)(de)高(gao)壓(ya)(ya)(ya)腔(qiang)與鋼(gang)(gang)瓶(ping)(ping)連(lian)接，低(di)壓(ya)(ya)(ya)腔(qiang)為(wei)氣體(ti)出(chu)口(kou)(kou)，并通(tong)往(wang)使(shi)(shi)用(yong)(yong)系(xi)統。高(gao)壓(ya)(ya)(ya)表的(de)(de)示值為(wei)鋼(gang)(gang)瓶(ping)(ping)內(nei)貯存氣體(ti)的(de)(de)壓(ya)(ya)(ya)力。低(di)壓(ya)(ya)(ya)表的(de)(de)出(chu)口(kou)(kou)壓(ya)(ya)(ya)力可由調節(jie)螺桿(gan)控制。 使(shi)(shi)用(yong)(yong)時(shi)先打(da)開鋼(gang)(gang)瓶(ping)(ping)總開關，然后順時(shi)針轉(zhuan)動(dong)低(di)壓(ya)(ya)(ya)表壓(ya)(ya)(ya)力調節(jie)螺桿(gan)，使(shi)(shi)其(qi)壓(ya)(ya)(ya)縮(suo)主彈簧并傳動(dong)薄膜、彈簧墊(dian)塊和頂(ding)桿(gan)而將活門(men)打(da)開。這樣進口(kou)(kou)的(de)(de)高(gao)壓(ya)(ya)(ya)氣體(ti)由高(gao)壓(ya)(ya)(ya)室經節(jie)流(liu)減壓(ya)(ya)(ya)后進入低(di)壓(ya)(ya)(ya)室，并經出(chu)口(kou)(kou)通(tong)往(wang)工作(zuo)系(xi)統。轉(zhuan)動(dong)調節(jie)螺桿(gan)，改變活門(men)開啟的(de)(de)高(gao)度(du)，從而調節(jie)高(gao)壓(ya)(ya)(ya)氣體(ti)的(de)(de)通(tong)過量并達到(dao)所(suo)需的(de)(de)壓(ya)(ya)(ya)力值。 氨(an)氣球閥(fa)(fa)都裝(zhuang)有安全閥(fa)(fa)。它是保(bao)護氨(an)氣減壓(ya)(ya)(ya)閥(fa)(fa)并使(shi)(shi)之安全使(shi)(shi)用(yong)(yong)的(de)(de)裝(zhuang)置，也(ye)是氨(an)氣球閥(fa)(fa)出(chu)現故障的(de)(de)信號(hao)裝(zhuang)置。如果由于(yu)活門(men)墊(dian)、活門(men)損壞或由于(yu)其(qi)它原因，導致出(chu)口(kou)(kou)壓(ya)(ya)(ya)力自行(xing)上(shang)升并超(chao)過一定許可值時(shi)，安全閥(fa)(fa)會自動(dong)打(da)開排(pai)氣。
