Abstract

The invention discloses an air foam fire extinguishing system for boats, which includes an air foam meter, an air foam storage tank, a discharge funnel, water supply equipment and high-pressure air supply equipment. There is a fresh water pipeline between the water supply equipment and the air foam storage tank; the high-pressure air supply equipment is connected to the air foam storage tank through a high-pressure air pipeline, and the high-pressure air pipeline is provided with a pressure gauge valve, Pressure reducing valve, safety alarm valve; air foam pipeline is provided on the air foam storage tank, the air foam pipeline is connected to the main pipe, and the connection is equipped with a right-angle stop check valve; the air foam pipeline is provided with throttling in sequence along the conveying direction Sleeve pipe and net type diffuser; The end of main pipe is connected with reel stand, and this reel stand is used for storing the tape hose with diffusion nozzle in each cabin of submarine; The aeromechanical foam that the present invention forms has high stability, Can keep 1‑1.5h.

Description

technical field [0001] The invention relates to the field of fire fighting equipment, in particular to an air foam fire extinguishing system for boats. Background technique [0002] At present, the fire extinguishing systems commonly used on boats include water-based fire extinguishing systems, foam fire extinguishing systems, dry powder fire extinguishing systems, halogenated hydrocarbon fire extinguishing systems and other new fire extinguishing systems, among which foam fire extinguishing systems are divided into chemical foam fire extinguishing and air foam fire extinguishing systems; The foam fire extinguishing system uses a certain amount of air foam liquid, water and air to form tiny dense film-like bubble groups filled with air through mechanical or hydraulic impact, so as to achieve the fire extinguishing effect. However, the foam formed by the existing air foam fire extinguishing system is not stable, and the shape retention effect is not high under the condition o...
