Description

Technical Field

[0001] The utility model relates to the technical field of air valves, and more specifically, to an air valve with a multi-branch wind force enhancement structure. Background Art

[0002] Positive pressure air supply vents are used to supply air under pressure when a fire occurs. Through the positive pressure air supply vents, air will be continuously supplied to the front room to maintain positive pressure in the front room, ensuring that smoke will not spread in this area, and providing space for people to escape. When the temperature is higher than 280℃, people can no longer escape, and the internal fuse will melt, and the air vent will automatically close to prevent the spread of fire. It is usually installed on the wall of the staircase front room and smoke shaft, and can also be installed on the side of the smoke control system pipe or the end of the air duct.

[0003] However, the common air supply valve air duct has no branches and the air volume is small. When the smoke is thick, it may not be able to quickly expel the smoke from the space. Moreover, the incoming air is not filtered and may carry a large amount of dust, which is harmful to health when inhaled. When there is a lot of dust, it may explode when exposed to open flames. There is generally an air supply port on the outside of the air supply valve to protect the air supply valve and make the air supply valve look beautiful. However, in order not to affect the air output, ventilation holes are generally opened. In this way, dust will fall into the air supply port and affect the opening and closing of the air supply valve.

[0004] In view of this, research and improvement are conducted on the existing problems, and a wind valve with a multi-branch wind enhancement structure is provided, aiming to achieve the purpose of solving the problems and improving the practical value through this technology.
