良工Q41B氨用球閥概述：

氨(an)用(yong)(yong)(yong)(yong)球閥在(zai)閥體(ti)(ti)材料(liao)上選(xuan)用(yong)(yong)(yong)(yong)耐腐(fu)(fu)蝕鋼(碳素(su)(su)鋼添加耐蝕合金(jin)元素(su)(su))，可耐燃氣(qi)(qi)、液氨(an)腐(fu)(fu)蝕，低溫可至－40℃-+120℃。我公司閥體(ti)(ti)全(quan)部采用(yong)(yong)(yong)(yong)精鑄，防止閥門耐腐(fu)(fu)蝕性能差、殼體(ti)(ti)易穿孔(kong)的(de)缺(que)點。主要適用(yong)(yong)(yong)(yong)于冷凍、制(zhi)冷、化工、石油(you)、食品、冶煉、液化氣(qi)(qi)等單位使用(yong)(yong)(yong)(yong)。氨(an)用(yong)(yong)(yong)(yong)球閥在(zai)物理化學(xue)實驗(yan)中，經常(chang)要用(yong)(yong)(yong)(yong)到氧氣(qi)(qi)、氮(dan)氣(qi)(qi)、氫氣(qi)(qi)、氬(ya)氣(qi)(qi)等氣(qi)(qi)體(ti)(ti)。這(zhe)些氣(qi)(qi)體(ti)(ti)一般都(dou)是貯存在(zai)專用(yong)(yong)(yong)(yong)的(de)高(gao)壓(ya)氣(qi)(qi)體(ti)(ti)鋼瓶中。使用(yong)(yong)(yong)(yong)時通過減(jian)壓(ya)閥使氣(qi)(qi)體(ti)(ti)壓(ya)力降至實驗(yan)所需范(fan)圍，再經過其它控制(zhi)閥門細調(diao)，使氣(qi)(qi)體(ti)(ti)輸入(ru)使用(yong)(yong)(yong)(yong)系(xi)統。最常(chang)用(yong)(yong)(yong)(yong)的(de)氨(an)用(yong)(yong)(yong)(yong)球閥為，簡稱氨(an)氣(qi)(qi)。 

良(liang)工(gong)(gong)Q41B氨用(yong)球閥工(gong)(gong)作原理： 

氨氣(qi)閥門(men)(men)的(de)高壓(ya)(ya)(ya)腔與鋼瓶(ping)連接(jie)，低壓(ya)(ya)(ya)腔為氣(qi)體(ti)(ti)出(chu)口(kou)(kou)，并(bing)通(tong)(tong)往使(shi)(shi)用系統(tong)。高壓(ya)(ya)(ya)表的(de)示值為鋼瓶(ping)內貯(zhu)存氣(qi)體(ti)(ti)的(de)壓(ya)(ya)(ya)力(li)(li)。低壓(ya)(ya)(ya)表的(de)出(chu)口(kou)(kou)壓(ya)(ya)(ya)力(li)(li)可由(you)(you)調節(jie)(jie)螺桿(gan)控(kong)制(zhi)。使(shi)(shi)用時先打(da)開(kai)鋼瓶(ping)總(zong)開(kai)關(guan)，然后順(shun)時針轉動(dong)低壓(ya)(ya)(ya)表壓(ya)(ya)(ya)力(li)(li)調節(jie)(jie)螺桿(gan)，使(shi)(shi)其壓(ya)(ya)(ya)縮主(zhu)彈簧并(bing)傳動(dong)薄(bo)膜、彈簧墊(dian)塊和頂(ding)桿(gan)而(er)將活(huo)(huo)門(men)(men)打(da)開(kai)。這樣進口(kou)(kou)的(de)高壓(ya)(ya)(ya)氣(qi)體(ti)(ti)由(you)(you)高壓(ya)(ya)(ya)室經(jing)(jing)節(jie)(jie)流減壓(ya)(ya)(ya)后進入低壓(ya)(ya)(ya)室，并(bing)經(jing)(jing)出(chu)口(kou)(kou)通(tong)(tong)往工(gong)作系統(tong)。轉動(dong)調節(jie)(jie)螺桿(gan)，改變(bian)活(huo)(huo)門(men)(men)開(kai)啟的(de)高度(du)，從而(er)調節(jie)(jie)高壓(ya)(ya)(ya)氣(qi)體(ti)(ti)的(de)通(tong)(tong)過量(liang)并(bing)達到所需的(de)壓(ya)(ya)(ya)力(li)(li)值。氨用球(qiu)閥都裝(zhuang)有(you)安(an)全(quan)閥。它是保護氨氣(qi)減壓(ya)(ya)(ya)閥并(bing)使(shi)(shi)之(zhi)安(an)全(quan)使(shi)(shi)用的(de)裝(zhuang)置，也(ye)是氨用球(qiu)閥出(chu)現故障的(de)信號(hao)裝(zhuang)置。如(ru)果由(you)(you)于(yu)活(huo)(huo)門(men)(men)墊(dian)、活(huo)(huo)門(men)(men)損壞或由(you)(you)于(yu)其它原因，導(dao)致(zhi)出(chu)口(kou)(kou)壓(ya)(ya)(ya)力(li)(li)自行上升(sheng)并(bing)超(chao)過一(yi)定許可值時，安(an)全(quan)閥會自動(dong)打(da)開(kai)排(pai)氣(qi)。
