Optionally, at 1023, after a period of time, a valve on the line is controlled to provide a third flow of bypass gas. Wherein the first flow rate is less than the second flow rate, and the second flow rate is less than the third flow rate. According to one embodiment of the present invention, the valves on the branches may be controlled to open simultaneously or partially; either partially or fully closed, so that a variety of different flow rates of the bypass gas can be provided for selection.

According to an embodiment of the invention, the concentration of the gas in the gas-tight enclosure and the concentration of the gas provided by the purity regulating device and the corresponding time can be integrated to more accurately control the valves on the nitrogen generator and/or the multiple branches. For example, the concentration of the nitrogen-oxygen separation unit output gas is adjusted according to the concentration of the gas in the airtight enclosure. The valves on the plurality of branches are adjusted according to the concentration or time of the gas provided by the purity adjusting device. Therefore, the invention provides a very flexible gas purity adjusting mode, which can improve the gas replacement efficiency in the airtight enclosure structure to the maximum extent and reduce the energy consumption.
