一、山东青岛老来寿生物实验室(shi)色谱仪管道安装技术要求

1、气瓶间

①气瓶间应(ying)采用300mm以上钢筋混凝土防(fang)(fang)爆墙，遮阳防(fang)(fang)晒(shai)，并(bing)安装防(fang)(fang)爆门，泄(xie)露窗。

②室内地面应(ying)有防火花、防静电(dian)措(cuo)施；室内电(dian)气设(she)备(bei)应(ying)具备(bei)防爆功能。

③通风良(liang)好，室内应(ying)安装排气扇。

④可燃(ran)气(qi)体钢瓶（氢气(qi)、乙炔）与助燃(ran)气(qi)体（氧气(qi)）应隔开放置。

⑤气瓶间(jian)要(yao)设置(zhi)报警系统(tong)

2、工作间(jian)

①所有管道要统筹规划、集中布置、方(fang)便安(an)装、便于操作、检修方(fang)便。

②所有工艺管道要设(she)置切断阀，并根据需要设(she)置压力表、温度计、流量计、过滤器和减压阀，阀门和仪表要设(she)置在(zai)便(bian)于(yu)观察和检修的地方。

③可燃气(qi)体管道要沿(yan)墙明线铺设，方便安装(zhuang)和(he)检修(xiu)。

④使用钢瓶气管道的设备(bei)台应离墙布置，且留出不小于600mm的检修空间。

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

⑥供(gong)气系统采用二级减(jian)压方式(shi)进行供(gong)气，气体由15Mpa减(jian)到(dao)(dao)1.5Mpa后再输入到(dao)(dao)各实验室。

二、用材

1、管(guan)(guan)道、球阀(fa)、三通和卡套均采用(yong)316L不锈(xiu)钢，高压软管(guan)(guan)为不锈(xiu)钢波纹管(guan)(guan)，在高压软管(guan)(guan)的进(jin)气(qi)端配(pei)置单向阀(fa)，防止(zhi)更换气(qi)瓶(ping)时，软管(guan)(guan)内的气(qi)体(ti)外(wai)泄(xie)，又(you)可防止(zhi)外(wai)界的空气(qi)混(hun)入气(qi)路中(zhong)，影(ying)响气(qi)体(ti)纯度(du)。

2、管道系统：所有(you)气(qi)体管道均(jun)采用B*别316L不(bu)锈钢管，在管路上有(you)过滤(lv)杂质和(he)水分的(de)装置。

3、管道的连(lian)(lian)接：汇排流、终端(duan)均采用卡(ka)套连(lian)(lian)接，便于减压(ya)器和阀门的维护管理。

4、终端：在(zai)每(mei)台仪(yi)器(qi)之前，配置截(jie)止阀和二级(ji)减压器(qi)，截(jie)止阀控制每(mei)个气路的开启和关(guan)闭，减压器(qi)用(yong)于显示和调整每(mei)个终端的压力。

5、气体管(guan)(guan)道每间(jian)隔1.5米采(cai)用(yong)管(guan)(guan)码支架固(gu)定。

6、整(zheng)个气路(lu)安装完毕(bi)后，对整(zheng)个系统做压力测试，压力24小时后无下降视为合格。
