自動切換(huan)(huan)(huan)集中(zhong)(zhong)(zhong)供(gong)氣(qi)(qi)裝置是將多只氣(qi)(qi)瓶分成左右兩(liang)組(zu)(zu)，分別將各(ge)個瓶中(zhong)(zhong)(zhong)的(de)氣(qi)(qi)體匯集在一起，經過減壓(ya)，通過管道向各(ge)用(yong)(yong)氣(qi)(qi)點供(gong)氣(qi)(qi)的(de)設備。工作時(shi)它首先(xian)使(shi)用(yong)(yong)一組(zu)(zu)瓶中(zhong)(zhong)(zhong)的(de)氣(qi)(qi)體，當(dang)該組(zu)(zu)瓶中(zhong)(zhong)(zhong)的(de)氣(qi)(qi)體耗盡(jin)時(shi)就(jiu)自動切換(huan)(huan)(huan)到另一組(zu)(zu)瓶供(gong)氣(qi)(qi)的(de)狀(zhuang)態，同時(shi)發出聲、光報(bao)警訊號(hao)以(yi)便值班人(ren)員(yuan)及時(shi)換(huan)(huan)(huan)下(xia)空瓶；當(dang)另一組(zu)(zu)瓶中(zhong)(zhong)(zhong)的(de)氣(qi)(qi)體耗盡(jin)時(shi)，又自動切換(huan)(huan)(huan)回先(xian)前的(de)狀(zhuang)態。這樣往(wang)復循(xun)環(huan)，就(jiu)能達到不(bu)間斷(duan)地穩定供(gong)氣(qi)(qi)的(de)目的(de)。

本自(zi)動切(qie)換集中供(gong)氣裝置(zhi)具(ju)有結構簡單、安(an)全可靠、操作方便(bian)，容是(shi)易(yi)維修等優點(dian)
