Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguisher nozzles, in particular to a water-based fire extinguisher nozzle with strong penetration power. Background Art

[0002] A fire extinguisher is an industrial product specifically used to extinguish, suppress or prevent the combustion of a fire. The water-based fire extinguisher generates foam by containing AFFF aqueous film-forming fire extinguishing agent and nitrogen inside. When it is sprayed onto the fuel surface, the water separated from the foam layer forms a water film on the fuel surface, isolating the combustible from the air. It has the advantages of high-efficiency flame retardancy, strong anti-re-ignition property, fast fire extinguishing speed and extremely strong permeability, so it is widely used. The fire extinguisher nozzle is an important part of the water-based fire extinguisher and is used to spray foam for fire extinguishing.

[0003] For example, the publication number is: CN211357554U, a water-based fire extinguisher nozzle, including a nozzle. A performance improvement device is arranged inside the nozzle. The performance improvement device includes anti-clogging flanges. The surfaces of the four anti-clogging flanges are evenly distributed on the upper surface of the nozzle, and the surfaces of the four anti-clogging flanges are fixedly connected to the upper surface of the nozzle. For this water-based fire extinguisher nozzle, by arranging a performance improvement device inside the nozzle, and the performance improvement device includes anti-clogging flanges, the fire extinguishing performance of the fire extinguisher is improved, the foaming components are reduced, the assembly efficiency is improved, and the cost is greatly reduced.

[0004] When a common water-based fire extinguisher nozzle is in use, although foam can be sprayed through the fire extinguisher nozzle for fire extinguishing, the spraying range of the existing fire extinguisher nozzle is generally fixed and difficult to adjust. Moreover, after the fire extinguisher nozzle is placed for a long time, dust will adhere to the spray holes, causing blockage and affecting the normal use of the fire extinguisher.
