一、山(shan)东青岛海洋生物(wu)医药研(yan)究院(yuan)实验室气体管路工(gong)程技(ji)术(shu)要求(qiu)

1、气瓶间

①气瓶间应(ying)采用300mm以上(shang)钢筋(jin)混凝土防(fang)(fang)爆墙，遮阳防(fang)(fang)晒(shai)，并安装防(fang)(fang)爆门，泄露窗。

②室内地面应(ying)有(you)防火花、防静电措(cuo)施；室内电气设备应(ying)具(ju)备防爆功(gong)能(neng)。

③通风良好，室内应安装排(pai)气扇(shan)。

④可(ke)燃(ran)气体钢瓶（氢(qing)气、乙(yi)炔）与助(zhu)燃(ran)气体（氧气）应(ying)隔(ge)开放(fang)置。

⑤气(qi)瓶间要设置报警(jing)系统

2、工(gong)作间

①所有管(guan)道要统筹规(gui)划、集中(zhong)布置、方便安装、便于(yu)操作、检修方便。

②所有工艺管道要设置(zhi)切断阀(fa)，并根(gen)据需要设置(zhi)压(ya)力表(biao)、温度计、流量(liang)计、过滤器和减压(ya)阀(fa)，阀(fa)门和仪(yi)表(biao)要设置(zhi)在便于观察和检修的地方。

③可燃气体管道要(yao)沿墙明线(xian)铺设，方(fang)便安装和(he)检(jian)修。

④使用(yong)钢瓶气管道(dao)的设(she)备台应离墙(qiang)布置，且(qie)留出不小(xiao)于600mm的检(jian)修空(kong)间(jian)。

⑤氢气管道应(ying)采(cai)用(yong)(yong)焊接连(lian)接，不能(neng)采(cai)用(yong)(yong)螺纹连(lian)接和使用(yong)(yong)闸阀。

⑥供(gong)气(qi)系统采用(yong)二级(ji)减压方式(shi)进行供(gong)气(qi)，气(qi)体由15Mpa减到(dao)1.5Mpa后再输入(ru)到(dao)各实验室。

二、用材(cai)

1、管道、球阀(fa)、三通和卡套均采用316L不锈钢，高压(ya)软(ruan)管为(wei)不锈钢波纹管，在高压(ya)软(ruan)管的进气(qi)(qi)(qi)端配置单向阀(fa)，防止更(geng)换气(qi)(qi)(qi)瓶时，软(ruan)管内的气(qi)(qi)(qi)体(ti)外泄，又可(ke)防止外界的空气(qi)(qi)(qi)混入(ru)气(qi)(qi)(qi)路中，影响气(qi)(qi)(qi)体(ti)纯度。

2、管道系统(tong)：所有(you)(you)气(qi)体管道均采(cai)用B*别316L不锈钢管，在管路上有(you)(you)过滤(lv)杂(za)质(zhi)和水(shui)分(fen)的(de)装置。

3、管(guan)(guan)道的连(lian)接：汇(hui)排流(liu)、终端均(jun)采(cai)用卡套(tao)连(lian)接，便(bian)于减压(ya)器和(he)阀门的维护管(guan)(guan)理。

4、终(zhong)端：在每台仪(yi)器(qi)(qi)之(zhi)前，配置截止(zhi)阀(fa)和二级(ji)减压器(qi)(qi)，截止(zhi)阀(fa)控制每个气路(lu)的开启和关闭，减压器(qi)(qi)用于显(xian)示和调整每个终(zhong)端的压力。

5、气体管(guan)(guan)道每(mei)间隔1.5米采用管(guan)(guan)码支架固定。

6、整个(ge)气路(lu)安装(zhuang)完毕后，对整个(ge)系统做压(ya)力(li)测试，压(ya)力(li)24小时后无(wu)下降视为合(he)格。
