氨氣球閥的外(wai)觀(guan)及工作原理: 

  氨用閥門(men)(men)的高(gao)壓(ya)腔與鋼瓶連接，低壓(ya)腔為(wei)(wei)氣體出口，并(bing)(bing)(bing)(bing)通(tong)往使用系統(tong)(tong)。高(gao)壓(ya)表(biao)的示值(zhi)(zhi)為(wei)(wei)鋼瓶內貯存(cun)氣體的壓(ya)力(li)(li)(li)。低壓(ya)表(biao)的出口壓(ya)力(li)(li)(li)可由(you)調(diao)節(jie)螺(luo)桿(gan)控制。 使用時先打開鋼瓶總開關，然(ran)后順時針轉動低壓(ya)表(biao)壓(ya)力(li)(li)(li)調(diao)節(jie)螺(luo)桿(gan)，使其(qi)壓(ya)縮主彈簧并(bing)(bing)(bing)(bing)傳動薄膜、彈簧墊(dian)塊和頂桿(gan)而將(jiang)活門(men)(men)打開。這樣進口的高(gao)壓(ya)氣體由(you)高(gao)壓(ya)室經(jing)節(jie)流減(jian)壓(ya)后進入(ru)低壓(ya)室，并(bing)(bing)(bing)(bing)經(jing)出口通(tong)往工作系統(tong)(tong)。轉動調(diao)節(jie)螺(luo)桿(gan)，改變活門(men)(men)開啟的高(gao)度，從而調(diao)節(jie)高(gao)壓(ya)氣體的通(tong)過(guo)量并(bing)(bing)(bing)(bing)達到所(suo)需(xu)的壓(ya)力(li)(li)(li)值(zhi)(zhi)。 氨氣球(qiu)閥都(dou)裝有(you)安全(quan)閥。它是保護氨氣減(jian)壓(ya)閥并(bing)(bing)(bing)(bing)使之安全(quan)使用的裝置，也是氨氣球(qiu)閥出現故障的信號裝置。如(ru)果由(you)于活門(men)(men)墊(dian)、活門(men)(men)損(sun)壞或由(you)于其(qi)它原因，導致出口壓(ya)力(li)(li)(li)自(zi)行上升并(bing)(bing)(bing)(bing)超過(guo)一定許可值(zhi)(zhi)時，安全(quan)閥會自(zi)動打開排氣。
