一、实验室仪器供气管道设计安装技术要求

1、气瓶间

①气瓶间应采(cai)用(yong)300mm以上钢筋混凝土防爆(bao)墙(qiang)，遮(zhe)阳(yang)防晒，并安装防爆(bao)门，泄(xie)露窗。

②室内(nei)地面应(ying)有防(fang)(fang)火花、防(fang)(fang)静电措施；室内(nei)电气(qi)设备应(ying)具(ju)备防(fang)(fang)爆功能。

③通风良好，室内(nei)应安装排气(qi)扇(shan)。

④可燃气(qi)体钢瓶（氢(qing)气(qi)、乙炔）与助(zhu)燃气(qi)体（氧气(qi)）应(ying)隔开放置。

⑤气瓶间要设置报(bao)警系统

2、工作间

①所有管道要统(tong)筹(chou)规划、集中布置、方便(bian)安装、便(bian)于操作、检(jian)修方便(bian)。

②所(suo)有工艺管道要设置(zhi)切(qie)断阀，并(bing)根据需要设置(zhi)压力表、温度计(ji)(ji)、流量计(ji)(ji)、过滤器和减压阀，阀门和仪(yi)表要设置(zhi)在(zai)便于观(guan)察(cha)和检(jian)修的地方。

③可燃(ran)气(qi)体管道要沿(yan)墙明线铺设，方(fang)便安装和检修。

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

⑤氢气管道应(ying)采用焊(han)接连接，不能采用螺纹连接和使用闸阀。

⑥供气(qi)系统采用二级减压(ya)方式进行供气(qi)，气(qi)体(ti)由(you)15Mpa减到(dao)(dao)1.5Mpa后再输(shu)入到(dao)(dao)各实(shi)验室(shi)。

二、实验室仪器供气管道设计安装(zhuang)用(yong)材

1、管(guan)道、球阀、三通和卡套(tao)均采用316L不锈(xiu)钢，高压软(ruan)管(guan)为不锈(xiu)钢波纹管(guan)，在高压软(ruan)管(guan)的(de)进(jin)气(qi)端配置(zhi)单(dan)向阀，防(fang)止更换气(qi)瓶(ping)时，软(ruan)管(guan)内的(de)气(qi)体(ti)外泄，又可防(fang)止外界的(de)空气(qi)混入气(qi)路中(zhong)，影响气(qi)体(ti)纯度。

2、管(guan)道(dao)系统：所有(you)气(qi)体(ti)管(guan)道(dao)均采用B*别(bie)316L不锈钢管(guan)，在管(guan)路上有(you)过滤杂质和水分的(de)装置。

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

4、终(zhong)端(duan)：在每(mei)台(tai)仪器之前，配置截止(zhi)阀(fa)和(he)二级减压(ya)器，截止(zhi)阀(fa)控制每(mei)个气(qi)路(lu)的(de)开启和(he)关(guan)闭，减压(ya)器用于显示(shi)和(he)调整(zheng)每(mei)个终(zhong)端(duan)的(de)压(ya)力。

5、气体管(guan)道每间隔1.5米采用(yong)管(guan)码支架(jia)固定。

6、整个气(qi)路(lu)安装完毕后(hou)，对(dui)整个系(xi)统做(zuo)压(ya)力(li)测试(shi)，压(ya)力(li)24小(xiao)时(shi)后(hou)无下降视为合(he)格。
