Abstract

The invention discloses an air supply pipe for air suction. A linear opening in the hole direction of the air supply pipe is formed in the pipe wall of the air supply pipe; the pipe wall adopts a rigid material; the pipe walls on the two sides of the opening are connected with a sealing strip I and a sealing strip II separately; and the sealing strip I and the sealing strip II are connected together through magnetic attraction and can be moved to open 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. 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. The air supply pipeline extends downwards and then extends a certain distance to the outside of the building. After adopting the above technical solution, escaped people can Open the valve or switch to inhale the air through the air outlet, because the air inlet of the air supply pipeline is arranged on the outside...
