高(gao)純氣(qi)(qi)體控(kong)制系(xi)統(tong)(tong)集(ji)中(zhong)(zhong)(zhong)供氣(qi)(qi)系(xi)統(tong)(tong)作為氣(qi)(qi)體儲存、調壓(ya)、輸送及(ji)供應(ying)具有(you)以下幾個優(you)點：一(yi)是集(ji)中(zhong)(zhong)(zhong)供氣(qi)(qi)系(xi)統(tong)(tong)將氣(qi)(qi)源(yuan)（鋼瓶）集(ji)中(zhong)(zhong)(zhong)在氣(qi)(qi)瓶儲存間，采(cai)用(yong)管(guan)路系(xi)統(tong)(tong)將氣(qi)(qi)送到(dao)所需(xu)的工作地(di)點，再將供氣(qi)(qi)終端進行分流。因此(ci)工作地(di)點看不(bu)到(dao)氣(qi)(qi)瓶，顯得(de)規范、整潔。二是結構緊湊、安(an)裝(zhuang)方便、操作簡單；三是集(ji)中(zhong)(zhong)(zhong)供氣(qi)(qi)系(xi)統(tong)(tong)更容易進行監控(kong)。因此(ci)采(cai)用(yong)集(ji)中(zhong)(zhong)(zhong)供氣(qi)(qi)系(xi)統(tong)(tong)進行供氣(qi)(qi)更安(an)全(quan)、更規范、更可(ke)靠。
