[0010] Furthermore, a main control valve is provided at one end of the main pipeline.

[0011] Furthermore, a control panel is fixedly connected to one side of the sealing cover plate, and the control panel is electrically connected to the temperature and humidity sensor.

[0012] The beneficial effects of the utility model are:

[0013] 1. By means of the arrangement that a plurality of contact switches are electrically connected to the solenoid valves, the cabinet can be individually filled with nitrogen, thereby avoiding the need to refill all the compartments with nitrogen, which is beneficial to nitrogen saving.

[0014] 2. By pressing the compression plate, the opening of the cabinet is in close contact with the sealing gasket, thereby improving the sealing of the cabinet and preventing nitrogen leakage.

[0015] 3.
