Next, the pressure controller 300 pressurizes the first sealing tube 210 and the second sealing tube 220 .

More specifically, as shown in Fig. 7, when a pressing operation is instructed, the start lamp L1 is turned on when the first pressure control valve 321 is in a closed state.

Then, an operation signal for opening the first pressure control valve 321 is applied, and the sealing execution lamp L2 is turned on. Here, the operation signal for opening the first pressure control valve 321 is a first pressure alarm unit 351 connected to the first sealing tube 210 and a second pressure alarm unit 352 connected to the second sealing tube 220. ) may not work. That is, the operation signal for opening the first pressure control valve 321 may be applied only when the internal pressures of the first sealing tube 210 and the second sealing tube 220 are equal to or less than a preset pressure.

Thereafter, the pressure regulating fluid is supplied from the fluid storage unit 310 to the first sealing tube 210 and the second sealing tube 220 . In addition, the first sealing tube 210 and the second sealing tube 220 expand, and the container 100 is sealed.

Next, when the internal pressures of the first sealing tube 210 and the second sealing tube 220 reach the preset pressure, the contact between the first pressure alarm unit 351 and the second pressure alarm unit 352 is closed, The sealing completion lamp (L3) turns on. Also, an operation signal for closing the first pressure control valve 321 may be applied.

In a state in which the pressing operation is completed, the container 100 may be transported by loading it on a vehicle or the like. In addition, by operating the air conditioner, the internal state of the container 100 may be adjusted.

Next, when the container 100 reaches its destination, a decompression operation is performed before opening the lid 120 .

When a pressure reduction operation is instructed, a signal for closing the first pressure control valve 321 is applied until the first pressure control valve 321 is closed.

Next, when the contact of the first pressure control valve 321 is closed, the pressure reduction preparation lamp (L4) is turned on.

Next, when the pressure reduction preparation lamp L4 is turned on, the first pressure reducing valve 331 and the second pressure reducing valve 332 are opened, and the pressure regulating fluid flows through the first sealing tube 210 and the second sealing tube 220. discharge to the outside. Accordingly, the first sealing tube 210 and the second sealing tube 220 contract, and the sealing of the container 100 is released. Then, the lead 120 may be opened.

A sealing system 10 for a container for a satellite and a method for sealing a container for a satellite using the same according to an embodiment of the present invention adjusts the pressure of the sealing part 200 disposed at the connection part of the container 100, so that the container 100 ) can be sealed. Through this, it is possible to prevent outside air from flowing into the container 100 or from leaking inside the container 100 to the outside, thereby preventing the container 100 from being damaged or damaged during transportation or storage.
