自动切换气体汇流排，专为两路气源之间的自动切换而设计，该系列气体汇流排不需操作者任何调试即可实现自动切换，即使在电器系统断电的状态下仍可正常工作。
Automatic switching gas mainfold , especially designed for automatic switching between the two gas source . This series of gas mainfold dose not need operator debug, it can realize automatic switching, Even in the state of short-curcit trouble, it can work as normal.  

半自动切换汇流排
半自动采用主供气瓶组和备用气瓶组双气源结构，当主供气瓶组的压力降至设定压力时，系统开始自动切换，由备用气瓶组开始供气，实现不间断供气功能，为实现下一次的自动切换，在空瓶进行调换后，必须对两个气瓶组的气体减压器重新进行设定。
Semi-automatic switching mainfold
Semi automatic mainfold adopts double source structure of main air bottle group and backup cylinder group, when the main air bottle group pressure is below the set pressure, automatic switching system begin supplying gas, showing the function of continous gas supply to realize the automatic switching for the next. After replacement of the empty bottles , regulator of the two cylinder group should be reset.


全自动切换汇流排是由于自动切换是利用气压平衡原理实现的，断电也能正常自动切换、正常工作的系统。采用原汇流排加上自动切换柜进行自动切换，当左侧气瓶的气体用完时自动切换到右侧气瓶进行供气。

Automatic switching gas cylinder adopts the principle of pressure balance to realize automatic switching. In the state of power cut, it can also automatically switch and work properly . The original mainfold automatically switch with automatic switch cabinet . When the gas in the left cylinder work outs, it automatically switch to the right cylinder for gas supply.
