Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of bearing pressure building, specifically relates to a bearing pressure sealing door with door frame and bearing pressure building containing the sealing door. BACKGROUND

[0002] In plateau areas, due to high altitude, low air pressure and low oxygen content, personnel from plain areas are prone to have heart rate acceleration, dizziness, physical decline, dehydration and other plateau reactions when traveling or working in plateau areas, which not only reduces the work, study efficiency and life quality of these personnel, and even has adverse effects on physical health in serious cases. In order to protect the physical health of personnel from low-altitude areas to work, live and travel in plateau areas, it is necessary to provide a pressurized oxygen supplement environment that can simulate low altitude, so that the human body can rest and recover in a relatively comfortable environment. A common method is to use a pressurized oxygen supplement building, that is, in a closed room, by increasing the pressure and supplementing oxygen in the room, the pressure and oxygen concentration in the room are increased to a level close to or equivalent to that of low-altitude areas, thereby relieving or even eliminating the human body's inadaptation to the plateau environment.
