High pressure water mist nozzle is a part of fire extinguishing system, its performance affects the normal operation of the whole fire extinguishing system. The high-pressure fine water mist nozzle can achieve the effect of fire extinguishing by atomizing liquid through the nozzle under high pressure.
 
High-pressure fine water mist fire fighting system is based on water as the medium, through a special nozzle, under a certain pressure, the water will be decomposed into fog drops for fire fighting; Because of its high fire fighting efficiency. Save water resources. Environmental protection pollution-free. Effectively reduce smoke hazards and other characteristics, gradually get more people's recognition and favor, High pressure water mist nozzle widely used in warehouses. Shopping malls. Hotels. Hospitals. Theaters, office buildings, high-rise buildings and garage and other places. Among these factors, what are the characteristics of high pressure fine water mist nozzles?
High pressure water mist fire fighting system is composed of high pressure pump set, special sprinkler head, system filter device, partition control valve, etc. Sprinkler head is the key to determine whether the system can spray fine fog droplets up to the standard, so the sprinkler head must be used for special fine water mist, such as open water mist nozzle sprinkler head, closed water mist nozzle sprinkler head, ultra-fine water mist nozzle head, etc.
 
The main material of high-pressure fine water mist nozzle is stainless steel 304/316 or brass H62/H59, and the nozzle part is also made of stainless steel 304/316. Using the swirl structure of special processing, the water is sprayed through the nozzle when the pressure is above 10MPa, forming fine fog droplets with particle size between 10 and 100um. The specific surface area and distribution density are increased, and the volume expansion is 1700~5800 times, so that the water mist has the dual fire fighting principle of efficient cooling and rapid suffocation.

Why can it be an important part of high-pressure water mist fire fighting system?

 
There are 5 mist atomizing nozzles in the high-pressure fine water mist nozzle, each nozzle is equipped with 200 mesh 316SS material, can play a good filtering effect, prevent atomization clogging, internal rotation design, more conducive to control the injection Angle, prolong the nozzle under high pressure service life, spray distance 3-8 meters; The high pressure water mist nozzle is also equipped with stainless steel nozzle filter net to filter impurities in the liquid. The stainless steel filter net is 40 mesh.
 
High-pressure fine water mist nozzle is a plurality of atomizing nozzles installed on the nozzle according to a certain arrangement, which can be divided into open and closed two types according to the mode of action.
 
Open high pressure water mist nozzle is composed of nozzle body, nozzle, nozzle core, filter and other parts. When the water with a certain pressure enters, the liquid is filtered into the nozzle through the nozzle, and then the pressurized water is spewed out from the nozzle hole at high speed. The water mist spewed out generates strong friction with the surrounding air, and the water is torn, thus forming fine water mist to spray along a certain Angle, so as to achieve the fire fighting effect.

Features of high-pressure fine water mist nozzle

1. Open high pressure water mist nozzle adopts stainless steel material, fine processing;
2. The number of water droplets emitted is very small, with the average water mist particle less than 100um. The droplets are densely distributed, uniform and last for a long time.
3. The perfect design of the internal flow channel of the open high-pressure fine water mist nozzle can make the water mist spray farther, and the unique vortex nozzle technology can not produce air resistance to the range;
4. High pressure water mist fire fighting system has a variety of injection angles and flow rates, which can be used in fire fighting environment and field.

Performance characteristics of high-pressure fine water mist sprinkler system

● Safe and pollution-free: water as fire fighting agent, safety to personnel, no damage and pollution to the environment;
● Smoke evacuation: smoke, gas washing and washing, improve the visibility of the fire site, easy to evacuate and fire rescue personnel;
● High fire fighting efficiency: both gas and traditional sprinkler suppression effect of two fire fighting systems. It removes oxygen like a gas fire fighting system, while cooling the flame like a water sprinkler system. Its cooling and wetting effect reduces the risk of fire recurrence. The fire fighting efficiency is 200-300 times that of the traditional sprinkler system;
● Good insulation performance: high pressure water mist fire water consumption is very small, most of the water mist evaporates after fire, water stains are very small, almost no impact on electronic components, can extinguish shelter fire, electrical fire;
● Block heat radiation: fine water mist system action, evaporation formed steam can quickly cover the combustion, flame and plume, the flame radiant heat has excellent barrier ability, but also can pre-wet near the combustion, to prevent the spread of fire effect;
● Small rescue loss: the water consumption of high pressure fine water mist is 1% of the traditional spray system, and the impact of small droplets on the protected object is small, greatly reducing the rescue loss, reduce the failure repair time caused by small fire and water damage loss;
● Easy installation and maintenance: less water consumption, without huge water storage, water supply equipment, and water mist pipe diameter is small, the material is corrosion resistant stainless steel, the whole system is easy to install and maintain;
● Strong applicability, reliability, flexible configuration;
