Abstract

The invention discloses a gas supply pipeline. According to the technical scheme, the pipe wall of the gas supply pipeline is provided with a linear opening in the direction of an internal hole of thegas supply pipeline, all or part of the pipe wall is made of an elastic material, the pipe wall at one side of the opening is fixedly connected with a sealing strip, the other side of the sealing strip is movably connected with the pipe wall at the other side of the opening, and the sealing strip can be moved to open the opening.

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...
