Abstract

The invention discloses a submarine air foam fire extinguishing system. The submarine air foam fire extinguishing system comprises an air foam batchmeter, an air foam storage tank, a discharge funnel,a water supply device and a high-pressure air supply device. The air foam batchmeter is connected with the air foam storage tank through a foaming agent pipe. A fresh water pipe is arranged between the water supply device and the air foam storage tank. The high-pressure air supply device is connected with the air foam storage tank through a high-pressure air pipe. The high-pressure air pipe is provided with a pressure gauge valve, a pressure reducing valve and a security alarm valve in the air supply direction in sequence. The air foam storage tank is provided with an air foam pipe. The air foam pipe is connected with a header pipe. A right-angle stop check valve is arranged at the joint between the air foam pipe and the header pipe. The air foam pipe is provided with a throttling casingpipe and a net-like diffuser in the delivery direction in sequence. The tail end of the header pipe is connected with a coiling block bracket. The coiling block bracket is used for storing a adhesiveplaster hose with a diffusion nozzle in each cabin of a submarine. Formed air mechanical foam has high stability and can be maintained for 1-1.5 h.

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...
