Abstract

The invention discloses an air supply pipeline. A pipe wall of the air supply pipeline is provided with a linear-shaped opening, pipe walls on the two sides of the opening are separated by a distance,or the pipe walls on the two sides of the opening are separated and can be opened, or the opening can be closed and opened, the pipe wall on one side of the opening is connected with a sealing stripI, the sealing strip I and the pipe wall on the other side of the opening are attracted magnetically to each other, or the sealing strip I and a sealing strip II connected with the pipe wall on the other side of the opening are attracted magnetically to each other, one or more sealing strips I or sealing strips II are arranged, the sealing strip I or the sealing strip II can be moved so that the opening can be opened, and meanwhile, several persons can get close to the opening to directly inhale through mouths or inhale by inserting vent pipes into the opening.

Description

technical field [0001] The present application relates to a gas supply pipeline. Background technique [0002] In building fires, smoke is the main cause of preventing people from escaping and causing the death of trapped people. [0003] When a fire breaks out in a building, in order to avoid the damage of smoke to people, the prior art is as follows: an air supply pipeline is arranged inside or outside the structure of the building, and the above-mentioned air supply pipeline is provided with an air outlet at a suitable position on the floor. The air inlet of the air supply pipeline extends to the outside of the building to communicate with the gas outside the building, and the air supply pipeline extends downwards and then extends a certain distance to the outside of the building. Therefore people can inhale the air that is not affected by smog by means of the air outlet, then hold back the breath and advance for a period of time such as 5-20 seconds, exhale the air at a...
