天津市华泽实验室气体管道系统安装产品概述：

天津市华泽实验室气体管道系统安装集中(zhong)供(gong)(gong)(gong)(gong)气(qi)(qi)(qi)(qi)(qi)(qi)(qi)系(xi)统(tong)(tong)作(zuo)为气(qi)(qi)(qi)(qi)(qi)(qi)(qi)体储存(cun)、调压、输送(song)及供(gong)(gong)(gong)(gong)应(ying)具有以下几(ji)个(ge)优点(dian)：一是集中(zhong)供(gong)(gong)(gong)(gong)气(qi)(qi)(qi)(qi)(qi)(qi)(qi)系(xi)统(tong)(tong)将气(qi)(qi)(qi)(qi)(qi)(qi)(qi)源(yuan)（钢瓶）集中(zhong)在(zai)气(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶储存(cun)间，采(cai)用管(guan)(guan)路系(xi)统(tong)(tong)将气(qi)(qi)(qi)(qi)(qi)(qi)(qi)送(song)到所需的工(gong)作(zuo)地点(dian)，再将供(gong)(gong)(gong)(gong)气(qi)(qi)(qi)(qi)(qi)(qi)(qi)终端进(jin)(jin)行(xing)分(fen)流。因此工(gong)作(zuo)地点(dian)看不到气(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶，显得(de)规范、整洁(jie)。二是结构紧凑、安装方便(bian)、操作(zuo)简(jian)单；三是集中(zhong)供(gong)(gong)(gong)(gong)气(qi)(qi)(qi)(qi)(qi)(qi)(qi)系(xi)统(tong)(tong)更容易进(jin)(jin)行(xing)监控。因此采(cai)用集中(zhong)供(gong)(gong)(gong)(gong)气(qi)(qi)(qi)(qi)(qi)(qi)(qi)系(xi)统(tong)(tong)进(jin)(jin)行(xing)供(gong)(gong)(gong)(gong)气(qi)(qi)(qi)(qi)(qi)(qi)(qi)更安全、更规范、更可靠。科望达(da)主要(yao)提(ti)供(gong)(gong)(gong)(gong)氧气(qi)(qi)(qi)(qi)(qi)(qi)(qi)、氢气(qi)(qi)(qi)(qi)(qi)(qi)(qi)、氦(hai)气(qi)(qi)(qi)(qi)(qi)(qi)(qi)、氮气(qi)(qi)(qi)(qi)(qi)(qi)(qi)、乙(yi)炔、压缩空气(qi)(qi)(qi)(qi)(qi)(qi)(qi)等(deng)气(qi)(qi)(qi)(qi)(qi)(qi)(qi)体的集中(zhong)供(gong)(gong)(gong)(gong)气(qi)(qi)(qi)(qi)(qi)(qi)(qi)系(xi)统(tong)(tong)设计及管(guan)(guan)路系(xi)统(tong)(tong)安装。

一、天津市华泽实验室气体管道系统安装技术要求

1、气瓶(ping)间

①气(qi)瓶间应采用300mm以上钢(gang)筋混凝土(tu)防爆墙，遮阳防晒，并安装防爆门，泄露窗。

②室(shi)内地(di)面应有防火花、防静电措施；室(shi)内电气设备应具备防爆功能。

③通风良好(hao)，室内应安装排气扇(shan)。

④可燃气体(ti)钢(gang)瓶（氢气、乙炔）与助(zhu)燃气体(ti)（氧(yang)气）应隔开(kai)放(fang)置。

⑤气瓶间(jian)要设置报警(jing)系统

2、工作间

①所有管(guan)道要统(tong)筹规划(hua)、集中布置、方便安装、便于操作、检修方便。

②所有工艺(yi)管道要(yao)设置切断阀，并根据需要(yao)设置压力表、温度计、流量计、过(guo)滤器和(he)(he)减压阀，阀门和(he)(he)仪表要(yao)设置在便于(yu)观察和(he)(he)检(jian)修的地方。

③可燃气体(ti)管道要(yao)沿墙明线铺设，方便安装和(he)检修。

④使用钢(gang)瓶(ping)气(qi)管道(dao)的设备台应(ying)离墙(qiang)布置，且(qie)留出不小于600mm的检修空间(jian)。

⑤氢(qing)气管道应采用(yong)焊接(jie)连接(jie)，不能采用(yong)螺纹连接(jie)和使用(yong)闸阀。

⑥供(gong)气(qi)系(xi)统采用二级减(jian)压方式进行供(gong)气(qi)，气(qi)体由(you)15Mpa减(jian)到(dao)1.5Mpa后(hou)再输入到(dao)各实验室。

二、用材(cai)

1、管(guan)道、球(qiu)阀、三通和卡套均采用316L不(bu)锈(xiu)钢，高压软管(guan)为不(bu)锈(xiu)钢波纹管(guan)，在高压软管(guan)的(de)进气端配置(zhi)单向阀，防止更换气瓶时(shi)，软管(guan)内的(de)气体外泄，又可防止外界的(de)空气混入气路(lu)中，影响气体纯度。

2、管(guan)道系统：所(suo)有气体管(guan)道均采(cai)用B*别316L不锈钢管(guan)，在(zai)管(guan)路上有过滤杂质和水分的装置。

3、管道的(de)连接：汇排流、终端均(jun)采用卡套(tao)连接，便于减(jian)压器和阀门的(de)维护管理。

4、终端：在每台仪器之(zhi)前，配(pei)置(zhi)截止阀和二级减(jian)压器，截止阀控制每个(ge)气(qi)路的开启和关(guan)闭，减(jian)压器用于显示(shi)和调整每个(ge)终端的压力。

5、气体管(guan)道每间隔1.5米采(cai)用(yong)管(guan)码支架固定。

6、整个气路安装完(wan)毕(bi)后，对整个系统做压(ya)力测试，压(ya)力24小时(shi)后无下降视为合格。
