What is Airlock?

Airlock is a special chamber used to input and output to a pressure environment such as submarines or spacecraft. It consists of two airtight doors and a central chamber in which air pressure and other factors can be controlled as needed. At the moment, only one air door is open; The second remains closed until the first door is sealed. This creates a leveling zone to maintain pressure and atmosphere in a closed environment. It also prevents decompression diseases, which is a potentially fatal condition caused by rapid changes in pressure on the human body. Caisson Choes, later known as a decompression disease, were complicated. The human body cannot adapt to rapid changes in external pressure; In extreme cases, death may occur. Finally, visitors to the underwater environment worshiped when the divers deep sea learned to use special chambers that slowly changed external pressure, allowing the body to adjust. Improvement in this technology has led to modern airby the air.

with the advent of space travel in the 20th century Airlock had a new purpose. The hard environment of the universe is numerous risks, including radiation, temperature extremes and atmospheric pressure. The spacecraft and space stations are equipped with air years so that astronauts can safely leave the vessel on the space feet or gears to other vehicles. Before the space time, astronauts will ever "camp" in the air air overnight. During this time, environmental pressure is slowly decreasing, preventing the onset of decompression disease.

Airlocks have other specialized uses in the earthly environment. The "clean rooms" used to produce electronics of high quality often have airlocks to prevent dust and contaminants. Chemical and radioactive laboratories use air equipment to prevent dangerous materials from leakage from controlled areas. Many public and privateThe buildings have two -door construction for well -used entrances. Although it is not really airtight, these passages are sometimes called air chambers because they help insulate the internal environment of the building from external conditions.

Airlocks are known to most people from their display in popular fiction. Underwater film dramas such as the Hunt for Red Octor and The Abyss have set tense scenes in the air or surroundings. TV shows such as Babylon 5 and Battlestar Galactica Reference to the Sci-Fi concept, sometimes called "gaps". This is a procedure for killing someone by throwing it out of the air air without a protective suit. Perhaps the most famous Airlock sequence will appear in 2001: Space Odyssey , in which the astronaut attempts to make manuals enter the spacecraft taken over by the computer.
