| titleOfInvention | Special gas manufacturing system |
| abstract | The utility model relates to a special gas manufacturing system, which comprises a first closed space and a second closed space, wherein the first closed space is arranged in the second closed space, the first closed space comprises special gas manufacturing equipment, and the second closed space outside the first closed space comprises an operation end for arranging the special gas manufacturing equipment; the first closed space comprises a first negative pressure maintaining device, and the first negative pressure maintaining device is used for enabling the first closed space to be in a first negative pressure state; the second sealed space is internally provided with a second negative pressure maintaining device, the second negative pressure maintaining device is used for enabling the second sealed space to be in a second negative pressure state, and the value of the second negative pressure state is larger than that of the first negative pressure state. The system can reduce the risk of leakage of the special gas of the operator and ensure the safety of the operator. |
