实验室气路工程

目前，实验室用气的主要特点是：仪器种类多，用气点分散，用气品种杂、工作压力不同。用气的仪器主要有气相、气质，液相，
液质，原子吸收，原子莹光，ICP，ICP-MS，TOC,测汞仪，氮吹仪等等。因此实验室集中供气系统的总体原则：实现功能，安全至
上，美观简捷。实现功能主要体现在通过集中供气系统给各实验室中的仪器提供稳定的压力、流量，保证气体的纯度与洁净度；


安全至上是指针对易燃易爆的气体如乙炔、氢气，氧
气，甲烷，有毒有害的一氧化碳，氨气等气体要根据
气体的特性采取必要的、安全的防护措施，将危险控
制在事前预防，事中监控中；美观简捷是指气路的走
向与布局需与整个实验室的环境相协调，同时方便工
作人员的使用。目前我们集中供气的气源分为气瓶柜、
气瓶间两种方式，采用单瓶、多瓶汇流排手动、自动

切换装置。同时根据客户现场与气体特性，可以选择低压报警、泄漏报警、紧急切断等安全配置。整个管道的连接在工艺上有全
自动焊接、卡套连接两种方式。

The main features are: at present, the laboratory gas instrument variety, gas dispersion, mixed gas varieties, different working

 pressure. Gas instruments which have spirit, temperament, liquid, liquid mass, atomic absorption, atomic jade-like stone light, 

ICP, icp-ms, TOC, mercury measurement instrument, blowing nitrogen, etc. So laboratory general principles of centralized gas 

supply system, realize the function, safe, beautiful and simple. Implement function mainly reflects in through the central gas 

supply system to the laboratory instruments in provide stable pressure and flow rate, ensure the gas purity and cleanliness; 

Safe is a pointer to flammable and explosive gases such as acetylene, hydrogen, oxygen and methane and carbon monoxide 

poisonous and harmful, such as ammonia gas according to the characteristics of the gas take necessary, safety protection 

measures, to control the risk prevention, monitoring, Beautiful and simple refers to the direction of gas circuit layout should be

 coordinated with the laboratory environment, the staff at the same time easy to use. Now we concentrate gas supply air into 

a cylinder tank, cylinder between two ways, using single bottle, bottle of bus-bar manual and automatic switching device. 

According to the customer site and gas characteristics at the same time, can choose low voltage alarm, leakage alarm, emergency 

cut-off security configuration, etc. The whole pipeline connection on craft are fully automatic welding, card sets of connection in
two ways.
