一、河北定州伊利乳业实验室气体管道工程技术要求

1、气瓶间

①气瓶间应采用(yong)300mm以上钢筋混凝(ning)土防(fang)爆(bao)墙，遮阳防(fang)晒，并安(an)装防(fang)爆(bao)门(men)，泄(xie)露(lu)窗。

②室内(nei)(nei)地面(mian)应有防(fang)火花(hua)、防(fang)静电措施；室内(nei)(nei)电气(qi)设(she)备应具备防(fang)爆功能。

③通风良好，室内(nei)应安装排气(qi)扇。

④可燃(ran)气(qi)体钢瓶（氢气(qi)、乙(yi)炔）与助燃(ran)气(qi)体（氧气(qi)）应隔(ge)开放置。

⑤气瓶间要(yao)设置报警系统

2、工作间

①所有管(guan)道要统(tong)筹(chou)规划、集(ji)中布置、方便(bian)(bian)安(an)装、便(bian)(bian)于操作、检修方便(bian)(bian)。

②所有(you)工艺管(guan)道要设(she)置(zhi)切断阀，并根据需要设(she)置(zhi)压力(li)表、温度计(ji)、流量计(ji)、过滤(lv)器和(he)减压阀，阀门和(he)仪表要设(she)置(zhi)在便于观察和(he)检修的(de)地方(fang)。

③可燃气体管道要沿(yan)墙明线铺设，方便安装和检修。

④使用钢瓶气(qi)管道的设备台应(ying)离墙(qiang)布置，且留出(chu)不小于600mm的检修空间。

⑤氢气管道应采(cai)(cai)用焊接连接，不能(neng)采(cai)(cai)用螺纹连接和使(shi)用闸阀。

⑥供(gong)气(qi)系统采(cai)用二(er)级(ji)减压方式进(jin)行供(gong)气(qi)，气(qi)体由15Mpa减到1.5Mpa后再输(shu)入到各实验室。

二、用材

1、管(guan)(guan)道、球阀(fa)、三通和卡套均采(cai)用(yong)316L不锈钢(gang)，高(gao)压软(ruan)管(guan)(guan)为不锈钢(gang)波(bo)纹管(guan)(guan)，在高(gao)压软(ruan)管(guan)(guan)的进气(qi)(qi)(qi)端配置单向阀(fa)，防止更换气(qi)(qi)(qi)瓶(ping)时，软(ruan)管(guan)(guan)内(nei)的气(qi)(qi)(qi)体外泄，又可防止外界(jie)的空(kong)气(qi)(qi)(qi)混入气(qi)(qi)(qi)路(lu)中(zhong)，影响气(qi)(qi)(qi)体纯度。

2、管(guan)道系(xi)统(tong)：所有气体管(guan)道均采用(yong)B*别(bie)316L不锈钢(gang)管(guan)，在(zai)管(guan)路(lu)上有过滤杂质(zhi)和(he)水分的装置。

3、管(guan)(guan)道的(de)连(lian)接(jie)：汇排流、终端(duan)均(jun)采(cai)用(yong)卡套连(lian)接(jie)，便于减压器和阀门的(de)维(wei)护管(guan)(guan)理。

4、终(zhong)端(duan)：在每(mei)台仪器(qi)之前，配置截止阀(fa)和(he)二(er)级减(jian)压器(qi)，截止阀(fa)控制每(mei)个气路的(de)开启和(he)关闭，减(jian)压器(qi)用于(yu)显(xian)示和(he)调整每(mei)个终(zhong)端(duan)的(de)压力。

5、气体管道每间隔(ge)1.5米采用管码(ma)支架固定。

6、整个气(qi)路安装完毕后，对整个系统做压力测试，压力24小时后无下降视为合格(ge)。
