化工实验室气瓶室管路改造产品概述：

化工实验室气瓶室管路改造集(ji)(ji)中(zhong)(zhong)(zhong)供(gong)(gong)(gong)气(qi)(qi)(qi)(qi)(qi)(qi)(qi)系(xi)(xi)(xi)统(tong)作(zuo)为气(qi)(qi)(qi)(qi)(qi)(qi)(qi)体储存、调压、输送(song)(song)及(ji)(ji)供(gong)(gong)(gong)应(ying)具有以下几个优点：一是(shi)集(ji)(ji)中(zhong)(zhong)(zhong)供(gong)(gong)(gong)气(qi)(qi)(qi)(qi)(qi)(qi)(qi)系(xi)(xi)(xi)统(tong)将气(qi)(qi)(qi)(qi)(qi)(qi)(qi)源(yuan)（钢瓶(ping)）集(ji)(ji)中(zhong)(zhong)(zhong)在气(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)储存间，采用管(guan)路系(xi)(xi)(xi)统(tong)将气(qi)(qi)(qi)(qi)(qi)(qi)(qi)送(song)(song)到(dao)所需(xu)的工(gong)作(zuo)地点，再将供(gong)(gong)(gong)气(qi)(qi)(qi)(qi)(qi)(qi)(qi)终端进行分流。因此工(gong)作(zuo)地点看(kan)不到(dao)气(qi)(qi)(qi)(qi)(qi)(qi)(qi)瓶(ping)，显得规范、整洁(jie)。二(er)是(shi)结(jie)构紧凑(cou)、安(an)装方(fang)便、操作(zuo)简单(dan)；三是(shi)集(ji)(ji)中(zhong)(zhong)(zhong)供(gong)(gong)(gong)气(qi)(qi)(qi)(qi)(qi)(qi)(qi)系(xi)(xi)(xi)统(tong)更(geng)容(rong)易进行监控。因此采用集(ji)(ji)中(zhong)(zhong)(zhong)供(gong)(gong)(gong)气(qi)(qi)(qi)(qi)(qi)(qi)(qi)系(xi)(xi)(xi)统(tong)进行供(gong)(gong)(gong)气(qi)(qi)(qi)(qi)(qi)(qi)(qi)更(geng)安(an)全(quan)、更(geng)规范、更(geng)可靠。科望达主要(yao)提供(gong)(gong)(gong)氧气(qi)(qi)(qi)(qi)(qi)(qi)(qi)、氢气(qi)(qi)(qi)(qi)(qi)(qi)(qi)、氦气(qi)(qi)(qi)(qi)(qi)(qi)(qi)、氮气(qi)(qi)(qi)(qi)(qi)(qi)(qi)、乙炔、压缩空气(qi)(qi)(qi)(qi)(qi)(qi)(qi)等气(qi)(qi)(qi)(qi)(qi)(qi)(qi)体的集(ji)(ji)中(zhong)(zhong)(zhong)供(gong)(gong)(gong)气(qi)(qi)(qi)(qi)(qi)(qi)(qi)系(xi)(xi)(xi)统(tong)设计及(ji)(ji)管(guan)路系(xi)(xi)(xi)统(tong)安(an)装。

一(yi)、化工实验室气瓶室管路改造技术要求

1、气瓶间

①气(qi)瓶间应(ying)采用300mm以上钢筋混凝土防(fang)爆(bao)墙，遮(zhe)阳(yang)防(fang)晒，并(bing)安装防(fang)爆(bao)门，泄露窗。

②室(shi)内地面应有防(fang)火花、防(fang)静电措施；室(shi)内电气设备应具备防(fang)爆功能。

③通风良好，室内应(ying)安装排气扇。

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

⑤气瓶间要(yao)设置报(bao)警系统

2、工作间

①所(suo)有管道(dao)要统筹(chou)规划、集中布置、方(fang)便(bian)安装、便(bian)于操作、检修方(fang)便(bian)。

②所有工(gong)艺管道要设(she)置(zhi)切断阀(fa)，并根据需要设(she)置(zhi)压力表、温度(du)计、流量计、过滤器和(he)减压阀(fa)，阀(fa)门和(he)仪表要设(she)置(zhi)在便于观察和(he)检(jian)修的地(di)方(fang)。

③可燃气体管(guan)道要(yao)沿墙明线铺设，方便安装和检(jian)修。

④使(shi)用钢瓶气管(guan)道(dao)的设备台应(ying)离墙布置，且留出不小于600mm的检修空间。

⑤氢(qing)气管(guan)道应采(cai)用(yong)(yong)焊接连接，不能采(cai)用(yong)(yong)螺纹连接和使用(yong)(yong)闸阀。

⑥供(gong)气(qi)(qi)系统采用二级减压(ya)方式进(jin)行供(gong)气(qi)(qi)，气(qi)(qi)体由15Mpa减到1.5Mpa后再(zai)输入到各实(shi)验室(shi)。

二、用(yong)材(cai)

1、管(guan)道、球阀、三通(tong)和卡套均采用316L不锈钢，高压软管(guan)为不锈钢波纹(wen)管(guan)，在高压软管(guan)的(de)进气(qi)(qi)端配置单向阀，防(fang)止(zhi)更换气(qi)(qi)瓶时，软管(guan)内的(de)气(qi)(qi)体外(wai)泄，又可防(fang)止(zhi)外(wai)界的(de)空(kong)气(qi)(qi)混入(ru)气(qi)(qi)路中，影响气(qi)(qi)体纯度。

2、管道系统：所有气体管道均采用B*别316L不锈钢管，在管路(lu)上(shang)有过滤杂质(zhi)和(he)水分(fen)的装置。

3、管道(dao)的(de)连(lian)接：汇排流、终端(duan)均采用卡套(tao)连(lian)接，便于减压器和阀门(men)的(de)维(wei)护管理。

4、终(zhong)端：在每台仪器之前(qian)，配置截止(zhi)阀和二(er)级减压(ya)器，截止(zhi)阀控制每个气路的(de)开启和关闭，减压(ya)器用于(yu)显(xian)示和调整每个终(zhong)端的(de)压(ya)力(li)。

5、气体管道每间隔(ge)1.5米采用管码支架固定(ding)。

6、整(zheng)个气(qi)路安(an)装完毕(bi)后(hou)，对整(zheng)个系统做压力测试，压力24小(xiao)时后(hou)无下降视为合格(ge)。
