Modern laboratory is often used in the test and analysis of H2,C2H2,O2,N2,Ar,He etc. The traditional laboratory gas supply mode is to set up a a gas cabinet near each location.It leads to redundant construction, brings safe hidden trouble and affects indoor design, the reason why choose the gathering gas supply is its merits :safety, economical efficiency,and aesthetic property have become the main trend for the development and of the construction of the laboratory.
現代實驗室在檢測分析中經常用到H2、C2H2、O2、N2、Ar、He等各種氣體，傳統的實驗室供氣方式是在每個用氣點附近設置一個氣瓶柜，造成重復建設，帶來安全隱患，影響室內美觀，集中供氣因為它的安全，方便、經濟、美觀已成為為實驗室發展和建設的大趨勢。
Laboratory gas supply / 實驗室供氣方式
1、Scattered gas and gas filling points less, and is decentralized.
分散供氣，同種氣體用氣點少，且分散分布時采用。
2、Central gas supply and gas gas, and a set of cloth used.
集中供氣，同種氣體用氣點多，且分集中布時采用。

Advantages of central gas supply / 集中供氣的優點
1、The ease of operation, security, and unified purchase gas cylinders, gas flammable and combustible properties distinguish the place. And ventilation, the firewall, the emergency cut off easy cylinder replacement and under-voltage alarm, measures, management, safety and security.
操作方便、安全性好，統一設置氣瓶間，將氣體按可燃和不可燃性質區分安置。并采取通風換氣，防火防爆，緊急切斷和欠壓報警等措施方便氣瓶更換、管理，安全有保障。
2、Pressure stability, high strength, through multiple levels decompression gases, each gas gas pressure and flow can be precisely adjusted, and displayed in real time, through the installation of gas purging replacement system, gas, high purity.
氣壓穩定、純度高，通過多級減壓方式供氣，每個用氣點的用氣壓力和流量可以調節，實時顯示，通過加裝氣路吹掃更換系統，供氣純度高。
3、Economical and clean appearance, can reduce the duplication of the same gas gas, bus, gas pipeline are integrated, neat appearance.
經濟實用，整潔美觀，可以減少同種氣體供氣匯流排的重復建設，供氣管道統一規劃，整潔美觀。

Made up of central gas supply system / 集中供氣系統的組成
1、Gas-source parts: cylinder (air supply) set cylinders placed in a specific room, through one-stage vacuum system (gas regulator or manifold) with gas under pressure into a low pressure gas.
氣源部分：氣瓶（氣源）集中安置在特定的氣瓶間，通過一級減壓系統（氣體減壓器或匯流排）將高壓氣體轉化成低壓氣體。
2、Piping parts: stainless steel pipeline to deliver the gas to the floor after equipment used in every room.
管道部分：經過（316#）不銹鋼管道將氣體送到各樓層各房間的儀器設備使用點。
3、Terminal part: the instrument is configured before cut-off valve and secondary pressure reducer, can make gas switches, precise adjustment and display air pressure.
終端部分：儀器前配置截止閥和二級減壓器等，可以制作氣路的開關，調整和顯示氣體壓力。
