Description

Double-claw type foam nozzle

Technical Field

The utility model relates to the technical field of fire-fighting equipment, in particular to a double-claw type foam nozzle.

Background

The foam nozzle is fire extinguishing equipment for generating and spraying air foam and is mainly used in low-expansion foam spraying systems. In the fire extinguishing process, the foam mixed liquid is conveyed to the foam nozzle through a pipeline, air is sucked at the outlet of the foam nozzle to form air foam, and the air foam is sprayed in a protected dangerous area to achieve the purpose of fire extinguishing. In the existing foam nozzle, the mixing effect of air and foam is poor in the fire extinguishing process, and the preset foaming multiple is difficult to achieve.

SUMMERY OF THE UTILITY MODEL

Based on this, the utility model aims to provide a double-claw type foam nozzle to enhance the mixing effect between air and foam.

The utility model provides a double claw formula foam nozzle, includes the shower nozzle main part, and inlays and locates nozzle in the shower nozzle main part, the terminal inside of nozzle is inlayed and is equipped with double claw board, two of the terminal of double claw board extend respectively on the surface and form the blocking claw that a plurality of intervals set up.

Compared with the prior art, the two surfaces of the double-claw plate are respectively provided with the blocking claws, the blocking claws collide with water flow in the spraying process, the contact area of the foam mixed liquid is increased, so that foam is increased, the sprayed foam mixed liquid is fully mixed with air, the foaming multiple of the foam mixed liquid is increased, and the range and the spraying area can be ensured.

Further, the blocking claws on both surfaces of the distal end of the double claw plate are arranged alternately.

Further, the gap between adjacent two blocking claws on the same surface is 2 mm.

Further, the blocking claw is of an arc-shaped structure.

Further, from the spray head main body to the direction of the double-claw plate, the thickness of the spray nozzle is gradually reduced, and the width of the spray nozzle is gradually increased.

Further, the width of the double-claw plate gradually increases from the spray head main body to the direction of the double-claw plate.

Furthermore, the nozzle is of a duckbilled flat structure, a boss is formed on the outer wall of the nozzle, and the boss is clamped at the end part of the sprayer body.
