自動切換氣體匯流排，專為兩路氣源之間的自動切換而設計，該系列氣體匯流排不需操作者任何調試即可實現自動切換，即使在電器系統斷電的狀態下仍可正常工作。
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.  

半自動切換匯流排
半自動采用主供氣瓶組和備用氣瓶組雙氣源結構，當主供氣瓶組的壓力降至設定壓力時，系統開始自動切換，由備用氣瓶組開始供氣，實現不間斷供氣功能，為實現下一次的自動切換，在空瓶進行調換后，必須對兩個氣瓶組的氣體減壓器重新進行設定。
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.


全自動切換匯流排是由于自動切換是利用氣壓平衡原理實現的，斷電也能正常自動切換、正常工作的系統。采用原匯流排加上自動切換柜進行自動切換，當左側氣瓶的氣體用完時自動切換到右側氣瓶進行供氣。

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.
