Embodiment Construction

[0044] Such as figure 1 said, figure 1 It is a cross-sectional view of the air supply pipeline 9 of the first embodiment of the present application. The pipe wall 1 of the air supply pipeline 9 of the first embodiment of the application is provided with a linear opening 2 along the hole direction of the air supply pipeline 9. The above opening 2 Through the pipe wall 1, the pipe wall 1 on one side of the opening 2 is provided with a strip-shaped L-shaped groove 3 for accommodating the sealing strip I6, and the pipe wall 1 on the other side of the above-mentioned opening 2 is provided with a strip for accommodating the sealing strip II7. Shaped L-shaped groove 5, L-shaped groove 3 is connected with sealing strip I6, L-shaped groove 5 is connected with sealing strip II7, and sealing strip I6 and sealing strip II7 are relatively close together to play the role of sealing opening 2. Insert the gap 8 between the sealing strip I6 and the sealing strip II7 directly or through the co...

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 extending direction of the gas supply pipeline, the pipe walls on the two sides of the opening are separated and are away from each other by a certain distance or the pipe walls on the two sides of the opening are closed and can be opened, all or part of the pipe wall is made of an elastic material, the opening of the gas supply pipeline can simultaneously allow a plurality of people to be close for sucking the air directly throughmouths or sucking the air by inserting a vent pipe into the opening, after the vent pipe is inserted into the gas supply pipeline, the pipe wall of the part, on the side edge of the opening, of the gas supply pipeline or a sealing component connected with the pipe wall of the part, on the side edge of the opening, of the gas supply pipeline can be wrapped around the vent pipe, and the vent pipe can move in the extending direction of the gas supply pipeline in 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...
