Embodiment Construction

[0022] The following is a specific implementation manner of the content of the present invention, and the content of the present invention will be further clarified through the specific implementation mode below. Of course, the following specific embodiments are described only to illustrate different aspects of the present invention, and should not be construed as limiting the scope of the present invention.

[0023] see figure 1 , figure 1 It is a schematic diagram of the connection between the packing box air distribution system and the packing box of the present invention. The packaging box gas distribution system 3 of the present invention is fixed on the spacecraft packaging box 1, and is communicated with clean air or high-purity nitrogen source 7 through an inflatable metal hose 6, so that when the spacecraft packaging box 1 needs to be inflated, the gas distribution system 3. Fill the clean air or high-purity nitrogen into the air distribution system through the infl...

Abstract

The invention discloses an automatic gas distribution system for a spacecraft packing box, which includes a solenoid valve, a pressure sensor, a mechanical pressure gauge, a manual valve, a pressure reducer and a pipeline. Through the cooperation of the solenoid valve, the manual valve and the pressure reducer, the Stability control of gas inside spacecraft crates. The invention is suitable for automatic monitoring and regulation of the pressure range in the packaging box during the transportation of aviation, aerospace, ships, weapons, precision instruments, precision electronics and other products in the packaging box or container, and protects the box body from pressure changes. damage, and protection from environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of spacecraft packaging boxes. Specifically, the invention relates to an automatic gas distribution system for spacecraft packaging boxes, which is used to monitor the pressure environment in the packaging box during storage or transportation of spacecraft products in a confined space and control. Background technique [0002] The spacecraft needs to be placed in a sealed packaging box during storage and transportation. The packaging box generally maintains a positive pressure of 0Pa to 3000Pa, and the gas filled is generally high-purity nitrogen. The maintenance of pressure is done through the box gas distribution system. One end of the gas distribution system is connected to the spacecraft packing box, and the other end is connected to a high-pressure high-purity nitrogen source. [0003] After the final assembly of domestic and foreign spacecraft, they need to be transported to their respective launch b...
