江西南昌大学实验室气相色谱气管安装产品概述：

江西南昌大学实验室气相色谱气管安装集(ji)(ji)中供(gong)(gong)(gong)(gong)气(qi)(qi)系(xi)(xi)统(tong)(tong)(tong)作为气(qi)(qi)体储存、调(diao)压(ya)、输送及供(gong)(gong)(gong)(gong)应具有以(yi)下几个优点：一(yi)是(shi)(shi)集(ji)(ji)中供(gong)(gong)(gong)(gong)气(qi)(qi)系(xi)(xi)统(tong)(tong)(tong)将(jiang)(jiang)(jiang)气(qi)(qi)源（钢(gang)瓶(ping)(ping)）集(ji)(ji)中在气(qi)(qi)瓶(ping)(ping)储存间，采用(yong)管(guan)路(lu)系(xi)(xi)统(tong)(tong)(tong)将(jiang)(jiang)(jiang)气(qi)(qi)送到所需的(de)工作地点，再(zai)将(jiang)(jiang)(jiang)供(gong)(gong)(gong)(gong)气(qi)(qi)终端进行分流(liu)。因此工作地点看不到气(qi)(qi)瓶(ping)(ping)，显得规(gui)范、整洁。二是(shi)(shi)结构(gou)紧(jin)凑、安(an)装方(fang)便(bian)、操(cao)作简单；三是(shi)(shi)集(ji)(ji)中供(gong)(gong)(gong)(gong)气(qi)(qi)系(xi)(xi)统(tong)(tong)(tong)更容易进行监(jian)控。因此采用(yong)集(ji)(ji)中供(gong)(gong)(gong)(gong)气(qi)(qi)系(xi)(xi)统(tong)(tong)(tong)进行供(gong)(gong)(gong)(gong)气(qi)(qi)更安(an)全、更规(gui)范、更可(ke)靠。科望达主(zhu)要提(ti)供(gong)(gong)(gong)(gong)氧(yang)气(qi)(qi)、氢气(qi)(qi)、氦气(qi)(qi)、氮(dan)气(qi)(qi)、乙炔、压(ya)缩(suo)空气(qi)(qi)等气(qi)(qi)体的(de)集(ji)(ji)中供(gong)(gong)(gong)(gong)气(qi)(qi)系(xi)(xi)统(tong)(tong)(tong)设计及管(guan)路(lu)系(xi)(xi)统(tong)(tong)(tong)安(an)装。

一、江西南昌大学实验室气(qi)相色谱气(qi)管(guan)安装技(ji)术要求

1、气瓶间

①气瓶间(jian)应采用300mm以(yi)上钢筋(jin)混凝土防爆(bao)墙，遮阳防晒，并安装防爆(bao)门，泄露窗。

②室内地面应(ying)有防火(huo)花、防静电(dian)措施；室内电(dian)气设(she)备应(ying)具(ju)备防爆功能。

③通(tong)风(feng)良好，室内应(ying)安装排气扇。

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

⑤气(qi)瓶(ping)间(jian)要设置报警系(xi)统

2、工(gong)作间(jian)

①所有管道要(yao)统筹规划、集中布置、方便安装、便于操作、检(jian)修(xiu)方便。

②所有(you)工(gong)艺管道(dao)要(yao)设(she)(she)置切断(duan)阀(fa)，并根据需要(yao)设(she)(she)置压力表、温度计、流量(liang)计、过滤器和减压阀(fa)，阀(fa)门和仪表要(yao)设(she)(she)置在便于(yu)观察和检修的地方。

③可燃气(qi)体管道(dao)要沿墙(qiang)明线铺设，方便安(an)装和(he)检(jian)修。

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

⑤氢气管道应(ying)采(cai)用焊(han)接(jie)(jie)连接(jie)(jie)，不能采(cai)用螺纹连接(jie)(jie)和使用闸(zha)阀。

⑥供(gong)气系统采用(yong)二级减(jian)压方式进行供(gong)气，气体由15Mpa减(jian)到(dao)1.5Mpa后(hou)再输入到(dao)各实验(yan)室。

二、用(yong)材

1、管(guan)道、球阀、三通和卡套均采用(yong)316L不(bu)锈钢，高压(ya)软(ruan)管(guan)为不(bu)锈钢波(bo)纹管(guan)，在高压(ya)软(ruan)管(guan)的(de)(de)进气(qi)端配(pei)置单向阀，防止更换(huan)气(qi)瓶(ping)时，软(ruan)管(guan)内的(de)(de)气(qi)体外(wai)泄，又可防止外(wai)界的(de)(de)空气(qi)混入气(qi)路(lu)中(zhong)，影响气(qi)体纯度。

2、管(guan)道系统：所有气体管(guan)道均采(cai)用B*别316L不锈(xiu)钢管(guan)，在管(guan)路上有过滤杂质(zhi)和水分的装置。

3、管道的(de)连接(jie)：汇排流(liu)、终端(duan)均采用(yong)卡套(tao)连接(jie)，便于减压器和阀门的(de)维(wei)护管理。

4、终端：在每(mei)台仪器(qi)(qi)之前，配置截(jie)止阀(fa)和二(er)级减(jian)压(ya)器(qi)(qi)，截(jie)止阀(fa)控制每(mei)个(ge)(ge)气路的开启和关闭，减(jian)压(ya)器(qi)(qi)用于显示和调整(zheng)每(mei)个(ge)(ge)终端的压(ya)力(li)。

5、气体管道每间隔1.5米采用管码支架固定(ding)。

6、整(zheng)个(ge)气路安装完毕后，对(dui)整(zheng)个(ge)系统做(zuo)压力测(ce)试(shi)，压力24小时后无下降视为合格。
