The structure principle of high-pressure water mist nozzle is introduced in the application of fire fighting field. The atomized particles of water mist nozzle are rapidly vaporized after fire, which can absorb a lot of heat and rapidly reduce the temperature of the combustion surface. At the same time, the combustion area is surrounded and covered as a whole, so that the combustion is asphyxiated due to hypoxia.
 
High pressure water mist nozzle is made of stainless steel nozzle. Can eject very fine atomizing particles, can eject very fine atomizing particles. Fine water mist sprinkler can achieve good effect in the field of fire fighting. So what is the structure of the water mist nozzle?

What is the structure principle of high pressure water mist nozzle for fire protection?

 
I. Introduction to the structure and principle of high-pressure fine water mist nozzle
The structure of water spray nozzle can spray fine atomization effect, the spray Angle of water spray nozzle is 45-90 degrees, and the diameter of atomized particles is 10-50um. Stainless steel nozzle core and stainless steel guide blade are inlaid in the water spray nozzle, which contains an anti-drip device. When the liquid is sprayed, it can produce high-speed flow under the water pressure of 20kg-120kg. A centrifugal vortex is formed in the guide blade, and very fine hollow fog particles are ejects from the nozzle hole.
 
Water mist nozzle structure is a kind of professional fire fighting water mist nozzle which is sprayed to extinguish fire by pressurizing the liquid to a certain pressure and then after atomizing the high-pressure water mist nozzle, and the high-pressure water mist nozzle needs to atomize the liquid to "water mist". The main material of high-pressure water mist nozzle is 316 stainless steel, which can withstand relatively high pressure. At the same time, the corrosion resistance and acid resistance of high-pressure water mist nozzle are better, and the service life is also very long.
 
1, high pressure water mist nozzle through pressure to achieve professional fine water mist, long service life.
The high-pressure fine water mist nozzle uses the swirl structure of special processing to atomize water into particles under high pressure. Usually, the average particle size of water mist is less than 100 microns, and the specific surface area and distribution density are high, and the cooling effect of vaporization and oxygen asphyxiation are stronger.
The high-pressure water mist sprinkler system uses easy and cheap water as the extinguishing medium. It is efficient, environmentally friendly, non-toxic and uses less water, and has little influence on the protected object water stains. 2, fine water mist nozzle adopts swirling nozzle structure, cooling effect and oxygen asphyxiation effect is stronger
The water mist nozzle can spray atomized particles with an average diameter of 10~50. Water mist sprinkler is a new and developing technology. Water mist sprinkler uses water droplets to extinguish flames. The atomized particles of water spray nozzle vaporize rapidly after fire, which can absorb a lot of heat, rapidly reduce the temperature of the combustion surface, and at the same time surround and cover the combustion area as a whole, so that the combustion is asphyxiated due to hypoxia.
The principle of high-pressure fine water mist sprinkler will surround and cover the combustion area as a whole, so that the combustion will be asphyxiated due to hypoxia. High pressure fine water mist nozzle can atomize liquid into fine water mist, long service life. The water mist ejected from the water mist nozzle structure can surround and cover the combustion area as a whole, so that the combustion is asphyxiated due to hypoxia. Achieve a good fire fighting effect.
 

The working principle of high pressure fine water mist nozzle

High-pressure fine water mist principle with water as fire extinguishing agent, is absolutely green environmental protection products, no harm to the human body and the environment, in addition, it also has the function of cleaning the toxic ingredients in the smoke and dust removal, is conducive to personnel escape, so it can realize the people-oriented design concept.
 
The principle of high-pressure fine water mist will not produce harmful gas after fire extinguishing, so it is not necessary to exhaust smoke separately in the fire mode, but drainage measures should be set in the equipment room of the pump room. The principle of high-pressure fine water mist nozzle is convenient and cheap because it takes water as fire extinguishing agent, while other gas fire extinguishing agent needs the production and procurement of professional manufacturers, so the procurement cost is higher. In addition, cooling is the main mechanism of high pressure water mist.
 
The fire-extinguishing medium of high-pressure fine water mist principle is water, which can achieve fire-extinguishing, fire suppression and fire control, moderate and dust control in various ways through efficient heat absorption, asphyxiation or radiant heat barrier.
 

High pressure fine water mist nozzle commonly used material

The main body of the high-pressure water spray nozzle is made of stainless steel 304SS, stainless steel 316SS and BRASS (banana-H62 and H59) (chrome plated), and the nozzle part is made of stainless steel 304SS and 316SS.
 

Characteristics of high-pressure fine water mist nozzle

 
1, the use of stainless steel material, all by CNC machining center precision machining;
2. The average particle size of the produced fine water droplets is less than 100um. The spatial distribution of droplets is dense and uniform, and the retention time is long.
3, the perfect inner flow channel design, so that the water spray farther, and the use of unique vortex jet hole technology, to overcome the air resistance on the impact of fog drop range;
4. The fire extinguishing system composed of a variety of spray angles and models can better adapt to the fire extinguishing environment and place;
