Abstract

A gas supply system, including a breathing air source, the gas supply system also includes a gas supply pipeline, the gas supply pipeline is connected to the breathing air source, the wall of the gas supply pipeline is provided with linear openings, The pipe wall on one side of the above-mentioned opening is directly or through a chain belt connected with an array of chain teeth I, and the pipe wall on the other side of the above-mentioned opening is directly or through a chain belt connected with an array of chain teeth II, and the above-mentioned chain teeth I and chain teeth II can be closed together or separated open.

Description

technical field [0001] The present application relates to a system for providing breathing air. Background technique [0002] There are many combustible decorations, chemical fiber carpets and furniture filled with foam plastics in modern buildings. These combustibles will produce a lot of toxic smoke and heat during combustion, and consume a lot of oxygen. In building fires, smoke is the main cause of preventing people from escaping and causing the death of trapped people. According to the statistics of the causes of casualties in fires in the UK, the death toll due to suffocation due to carbon monoxide poisoning or other toxic smoke generally accounts for 40% to 50% of the total death toll, and among the people who were burned to death, most of them were poisoned first. Burned to death after asphyxiation. When a fire breaks out, because combustion consumes a lot of oxygen, the oxygen concentration in the air drops significantly. If people stay in this hypoxic environment...
