Abstract

The invention discloses a temperature and pressure adjusting device for a spacecraft environment test. The temperature and pressure adjusting device comprises a vacuum container, a container gate, a heat sink, a control cabinet, a refrigerator and the like. The heat sink is placed in the vacuum container. The heat sink and the refrigerator are connected through a refrigerating pipeline. A refrigerating valve is connected with the middle of the refrigerating pipeline. A heat exchanger communicates with the refrigerating pipeline through a heat exchanger pipeline. The vacuum container and a vacuum pump are connected through a vacuum pipeline. A vacuum valve is connected with the middle of the vacuum pipeline. A gas supplying pipeline is connected with the vacuum container. A gas flow controller is installed on the gas supplying pipeline. Gas in the gas supplying pipeline firstly enters the heat exchanger for heat exchanging before entering the vacuum container. A nitrogen pipeline and anair pipeline are arranged in parallel. A nitrogen source is connected with the gas supplying pipeline through the nitrogen pipeline. An air source is connected with the gas supplying pipeline throughthe air pipeline. An air dryer is connected to the middle of the air pipeline. The control cabinet is connected with the refrigerator, the refrigerating valve, the vacuum pump, the vacuum valve and the gas flow controller by controlling cables.

Description

technical field [0001] The invention belongs to the technical field of environmental test devices, and in particular relates to a test device whose internal pressure and temperature can be precisely and automatically adjusted, and is used for spacecraft to carry out environmental tests. Background technique [0002] During the process of the spacecraft rising from the ground to the high altitude, the pressure and temperature in the environment are constantly changing. In order to verify the environmental adaptability and reliability of the spacecraft, a special temperature and pressure regulation environmental test device is required to carry out environmental tests. The main structure of the test device is a vacuum container, heat sink, control cabinet, refrigerator, refrigeration pipeline, heat exchanger, vacuum pump, vacuum pipeline, vacuum valve, gas flow controller, gas source, etc. Existing temperature and pressure regulation test devices used for spacecraft environme...
