Abstract

An air foam firefighting gun, made up of structures such as: an air foam mixture nozzle (11) arranged at a front end; an air inlet (12) arranged on the same axis as the mixture nozzle (11) and at a rear end; a firefighting agent mixture inlet (7) and a firefighting agent mixture outlet (8) arranged at the centre of the axis of the air inlet (12); water jet inclined openings (10) arranged at the junction between the mixture nozzle (11) and the air inlet (12) in an evenly spaced and surrounding manner and in communication with an annular liquid cavity (9); a water inlet (4). The air foam firefighting gun uses wind power as a firefighting jetting force, may be applied as an air firefighting device to situations such as forest firefighting, and may be applied to many types of firefighting situations. The structure of the jetting system is optimised, the firefighting agent is driven to foam and jet by the force wind, and the jetting distance is large. The air foam firefighting gun uses surrounding tilted liquid outlets, generates a greater negative pressure, sucks in more air, and generates a higher foaming factor. The fluid flows without resistance, the device is recoilless, the jetting distance is further, the foam proportion may be adjusted or even turned off, and the device has a wider range of applications.

Description

technical field [0001] The invention relates to a fire extinguishing appliance, in particular to an air foam fire extinguishing device comprising air, foam fire extinguishing agent and water as fire extinguishing media. Background technique [0002] In air and foam fire extinguishing systems, the sufficient degree of gas-liquid mixing is related to the foaming ratio of the foam fire extinguishing agent. The foaming ratio is an important indicator of the fire extinguishing efficiency of the system, and the spraying distance of the foamed mixed liquid is the key to the fire extinguishing application ability of the system. important performance indicators. [0003] Existing fire extinguishing systems include fixed or mobile fire extinguishing systems. Both fixed and mobile fire extinguishing systems mainly use liquid pumps as the injection power. The spray distance of the foam fire extinguishing agent formed is limited and the coverage is poor. The fire extinguishing needs of ...
