Abstract

The invention discloses a gas supply pipeline. The pipe wall of the gas supply pipeline is provided with a linear opening formed in the extending direction of the gas supply pipeline, the portions, onthe two sides of the opening, of the pipe wall are closed to form a fracture gap, the fracture gap can be opened, multiple vent pipes can be contained in the opening and can move in the extending direction of the gas supply pipeline in the opening, the portions, on the two sides of the fracture gap, of the pipe wall are in a closed state or in a staggered lap-joint state when the gas supply pipeline does not bear external force, and the pipe wall is completely or partially made of an elastic material.

Description

technical field [0001] The present application relates to a gas supply pipeline. 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 for a long tim...
