The High pressure foam water mist nozzle is a part used in the fire extinguisher system to mist spray the foam mixture to produce foam, and foam water mist nozzle can also spray water mist, which is composed of the nozzle shell, foam water mist nozzle head, splashing pan and filter screen. The foam mixture is ejected from the inner flow channel of the nozzle shell to the nozzle to form foam, and the protected area is put out fire.

Characteristics of High pressure foam water mist nozzle fire extinguishing system

Double fire extinguishing form
High pressure foam water mist nozzle has dual fire extinguishing form of water spray and foam fire, which can effectively fight complex Class A and Class B composite fires in tunnels
Strong choking and foam water mist fire extinguishing effect
Water film and foam formed by water film foam extinguishing agent have strong adhesion, foam water mist nozzle can effectively cover combustible materials, and have remarkable oxygen asphyxiation effect
Cooling speed is fast
Water spray cooling efficiency is high, shielding thermal radiation to protect the tunnel structure, wash toxic and harmful fumes to help personnel evacuate safely
Safety and Environmental Protection
Compact structure, easy to operate, safe and environmentally friendly

Working principle

The high pressure foam water mist nozzle is used together with the fixed foam fire extinguishing system. The foam mixture required by the foam mist nozzle is provided by the foam proportional mixing device, which is suitable for the low expansion foam mixture of 3% or 8%.
When the foam mixture is transported to the foam water mist nozzle through the pipeline, the mixed liquid is fully mixed with the air inhaled inside the nozzle to form a diffused atomized jet, which touches the inner wall of the nozzle and the foam disperser to form eddy current, and thus foams into a low-expansion foam. Then, the foam is evenly mist sprayed in the surrounding protection area through the umbrella type water baffle plate to cover the surface of the burning object. Suffocate, cool and put out fires.

2. Installation
(1) When the sagging foam water mist nozzle is installed, the umbrella baffle plate faces down, and when the upright foam nozzle is installed, the umbrella baffle plate faces up.
(2) The inlet aperture of the pipe for installing the foam water mist nozzle shall not be less than the inlet size of the nozzle, and measures shall be taken to prevent foreign bodies from blocking the nozzle according to the needs of the project.
(3) The foam water mist nozzle sprinkler head should be installed in a place that will not suffer mechanical damage. Before installation, it should be confirmed that the foam water mist nozzle specifications, models, connection dimensions and other parameters meet the requirements.
Foam water mist nozzle fire extinguishing system using high efficiency foam liquid as fire extinguishing agent, under a certain pressure through the special foam spray nozzle, the fire extinguishing agent is sprayed to the protected object, so that it quickly extinguish a new fire extinguishing device. The device absorbs the characteristics of water mist fire extinguishing and foam fire extinguishing at the same time. It has advanced technology, high fire extinguishing efficiency, simple installation and maintenance, and is an efficient, safe, economic and environmental protection fire extinguishing device. The device has three starting modes: automatic, manual and mechanical emergency operation.
