Structural principle of high pressure water mist fire extinguishing nozzle

The water mist nozzle is made of stainless steel nozzle. Can eject very fine atomized particles, can eject very fine atomized particles. The water mist sprinkler is used in the field of fire fighting and can achieve a good fire fighting effect. So what is the structure of the water mist nozzle? What is the structure principle of high pressure water mist nozzle?

Water Mist Nozzle

The structure principle of high pressure water mist nozzle

The principle of high pressure water mist uses water as the fire extinguishing agent. It is an absolute green environmental protection product, without any harm to the human body and the environment. In addition, it also has the function of cleaning the toxic components in the smoke and reducing dust, which is conducive to the escape of people, so it can realize the people-oriented design concept. The principle of high pressure water mist will not produce harmful gas after extinguishing the fire. Therefore, it is not necessary to exhaust smoke separately in fire mode, but drainage measures need to be set up in the equipment room of the pump room.

The principle of high-pressure water mist nozzle is that water is used as the fire extinguishing agent, so it is convenient and cheap to obtain materials, while other gas fire extinguishing agents need to be produced and purchased by professional manufacturers, so the purchase cost is high. In addition, because the high pressure water mist takes cooling as the main fire extinguishing mechanism.

The fire-extinguishing medium of the high-pressure water mist principle is water, which can protect the protected object in various ways of extinguishing, suppressing and controlling fire, controlling temperature and reducing dust through efficient heat absorption, suffocation or blocking of radiant heat.

The principle of high-pressure water mist sprinklers works through the hypoxia of fire extinguishing. When the fine water mist is sprayed into the fire field, it can quickly evaporate to form steam, and expand rapidly through the product to expel the air to the outside. The entry of air, and then according to the principle of high-pressure water mist nozzles can reduce the oxygen concentration in the combustion area and make the fire oxygen-deficient.

The structure of the water mist nozzle can spray the effect of fine atomization. The spray angle of the water mist nozzle is from 45-90 degrees, and the diameter of the atomized particles is 10~50um. The water mist nozzle is inlaid with stainless steel nozzle core and stainless steel guide vane. It contains an anti-drip device. When spraying, the liquid can flow at a high speed under the water pressure of 20kg-120kg, forming a centrifugal vortex in the guide vane, and spraying extremely fine hollow mist particles from the nozzle hole.
