Problems solved by technology

[0004] (2) For the side spray nozzle, the coverage of the spray medium is fan-shaped, and the two fan-shaped intersections formed by two similar nozzles always have a part that cannot be covered, and because the side spray nozzle is used to ensure the spraying distance, a baffle is used at the outlet of the nozzle The plate blocks the jet to achieve the atomization effect, this atomization effect is not good

Abstract

The invention provides a foam nozzle which comprises a main body, a first nozzle unit, a second nozzle unit, a third nozzle unit and a fourth nozzle unit, wherein the main body is a cylinder with a hollow cavity; a pipe joint communicated with the hollow cavity is formed in the upper end of the main body, and the lower end of the main body is closed; four nozzle joints which are peripherally distributed in equal distance are formed in the outer circumference of the main body; the first nozzle unit, the second nozzle unit, the third nozzle unit and the fourth nozzle unit are sequentially connected onto the four nozzle joints and communicated with the hollow cavity of the main body; the injection direction of the first nozzle unit, the second nozzle unit, the third nozzle unit and the fourth nozzle unit is inclined downwards; the first nozzle unit and the third nozzle unit are short-range nozzles; and the second nozzle unit and the fourth nozzle unit are long-range nozzles. According to the foam nozzle disclosed by the invention, a blind area between two adjacent foam nozzles is absent during use, and the all-coverage aim is achieved.

Description

Technical field [0001] The invention belongs to the field of fire fighting and extinguishing, and particularly relates to a foam nozzle. Background technique [0002] At present, in the use of foam sprinklers, two similar sprinklers cannot be completely joined, and there is a certain blind area at the intersection. There are mainly two existing solutions: self-rotating nozzles and side-jet nozzles. [0003] (1) The self-rotating nozzle takes the nozzle itself as the center of the circle, and the coverage of the spray medium is a circle. The intersection of the two circles formed by two similar nozzles will always have a part that cannot be covered; [0004] (2) Side spray nozzles, the coverage of the spray medium is fan-shaped, and part of the intersection of the two sectors formed by two similar nozzles will always fail to cover, and because the side spray nozzles ensure the spray distance, a stopper is used at the nozzle outlet. The plate blocks the jet to achieve the atomization...
