蕪湖三利日化實驗室高純氣體壓力管道安裝集(ji)中(zhong)供(gong)(gong)氣(qi)(qi)(qi)(qi)(qi)(qi)系(xi)(xi)統(tong)(tong)(tong)作(zuo)為氣(qi)(qi)(qi)(qi)(qi)(qi)體儲存、調壓(ya)、輸送(song)及供(gong)(gong)應具有(you)以(yi)下幾(ji)個優(you)點(dian)(dian)：一(yi)是(shi)集(ji)中(zhong)供(gong)(gong)氣(qi)(qi)(qi)(qi)(qi)(qi)系(xi)(xi)統(tong)(tong)(tong)將(jiang)氣(qi)(qi)(qi)(qi)(qi)(qi)源（鋼瓶(ping)）集(ji)中(zhong)在(zai)氣(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)儲存間，采用(yong)(yong)管(guan)路系(xi)(xi)統(tong)(tong)(tong)將(jiang)氣(qi)(qi)(qi)(qi)(qi)(qi)送(song)到所需的(de)工(gong)作(zuo)地點(dian)(dian)，再將(jiang)供(gong)(gong)氣(qi)(qi)(qi)(qi)(qi)(qi)終(zhong)端進行(xing)分(fen)流。因此工(gong)作(zuo)地點(dian)(dian)看(kan)不到氣(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)，顯(xian)得規范(fan)、整潔(jie)。二是(shi)結構緊湊(cou)、安裝方便、操作(zuo)簡(jian)單；三是(shi)集(ji)中(zhong)供(gong)(gong)氣(qi)(qi)(qi)(qi)(qi)(qi)系(xi)(xi)統(tong)(tong)(tong)更(geng)(geng)容易進行(xing)監控。因此采用(yong)(yong)集(ji)中(zhong)供(gong)(gong)氣(qi)(qi)(qi)(qi)(qi)(qi)系(xi)(xi)統(tong)(tong)(tong)進行(xing)供(gong)(gong)氣(qi)(qi)(qi)(qi)(qi)(qi)更(geng)(geng)安全、更(geng)(geng)規范(fan)、更(geng)(geng)可(ke)靠。科(ke)望達主(zhu)要(yao)提供(gong)(gong)氧(yang)氣(qi)(qi)(qi)(qi)(qi)(qi)、氫氣(qi)(qi)(qi)(qi)(qi)(qi)、氦氣(qi)(qi)(qi)(qi)(qi)(qi)、氮氣(qi)(qi)(qi)(qi)(qi)(qi)、乙炔、壓(ya)縮空氣(qi)(qi)(qi)(qi)(qi)(qi)等(deng)氣(qi)(qi)(qi)(qi)(qi)(qi)體的(de)集(ji)中(zhong)供(gong)(gong)氣(qi)(qi)(qi)(qi)(qi)(qi)系(xi)(xi)統(tong)(tong)(tong)設計及管(guan)路系(xi)(xi)統(tong)(tong)(tong)安裝。

一、蕪湖三利日化實驗室高純氣體壓力管道安裝技術要(yao)求

1、氣瓶(ping)間

①氣瓶間(jian)應采用300mm以(yi)上鋼(gang)筋混凝土(tu)防(fang)(fang)爆(bao)墻，遮(zhe)陽防(fang)(fang)曬，并(bing)安裝防(fang)(fang)爆(bao)門，泄露窗。

②室(shi)內地(di)面應(ying)有防(fang)火花、防(fang)靜電措施；室(shi)內電氣設備(bei)應(ying)具備(bei)防(fang)爆功能。

③通風良好，室(shi)內應安裝排(pai)氣扇。

④可燃氣(qi)體(ti)鋼瓶(ping)（氫氣(qi)、乙炔(gui)）與助燃氣(qi)體(ti)（氧(yang)氣(qi)）應(ying)隔開放(fang)置。

⑤氣瓶(ping)間要(yao)設置報警系統

2、工作間(jian)

①所有(you)管道(dao)要(yao)統(tong)籌(chou)規(gui)劃(hua)、集中布置、方(fang)便(bian)安裝、便(bian)于操作(zuo)、檢(jian)修方(fang)便(bian)。

②所有工藝(yi)管道要(yao)設置切斷(duan)閥，并(bing)根(gen)據需要(yao)設置壓(ya)力表(biao)、溫度計、流量計、過濾器(qi)和減壓(ya)閥，閥門和儀(yi)表(biao)要(yao)設置在便(bian)于觀察和檢修的地方。

③可(ke)燃氣體管道要沿(yan)墻明線鋪設，方便(bian)安裝(zhuang)和檢修(xiu)。

④使用鋼瓶氣管道的(de)設備臺應(ying)離墻布置，且留出不小于600mm的(de)檢(jian)修(xiu)空間。

⑤氫氣管(guan)道應采(cai)用焊接(jie)(jie)連(lian)接(jie)(jie)，不(bu)能采(cai)用螺紋連(lian)接(jie)(jie)和使用閘(zha)閥。

⑥供氣(qi)(qi)(qi)系統采用二級減壓方式進(jin)行供氣(qi)(qi)(qi)，氣(qi)(qi)(qi)體由15Mpa減到1.5Mpa后再(zai)輸入到各(ge)實(shi)驗室。

二、用材(cai)

1、管(guan)道、球閥、三通和卡套均采(cai)用(yong)316L不銹鋼，高壓軟管(guan)為不銹鋼波紋(wen)管(guan)，在(zai)高壓軟管(guan)的(de)進氣(qi)端(duan)配置(zhi)單(dan)向閥，防(fang)止更換氣(qi)瓶時，軟管(guan)內的(de)氣(qi)體外泄，又可防(fang)止外界的(de)空氣(qi)混入氣(qi)路中，影響氣(qi)體純度。

2、管道系統(tong)：所有氣體管道均采(cai)用B*別316L不(bu)銹鋼管，在管路上(shang)有過濾(lv)雜質和(he)水分的裝置。

3、管道的連接：匯排流、終端均采(cai)用卡套連接，便于(yu)減壓(ya)器和閥門的維護管理。

4、終端：在每(mei)臺儀器(qi)之前，配置截止(zhi)閥和(he)二級減壓器(qi)，截止(zhi)閥控制每(mei)個氣路(lu)的(de)開啟和(he)關閉，減壓器(qi)用于(yu)顯示和(he)調整(zheng)每(mei)個終端的(de)壓力。

5、氣體管道每間隔(ge)1.5米采用管碼支架固定。

6、整個氣路安裝(zhuang)完畢(bi)后(hou)，對(dui)整個系統做壓(ya)(ya)力測試，壓(ya)(ya)力24小時(shi)后(hou)無下降視(shi)為合格。
