High pressure water mist is stable and reliable performance, installation, maintenance, easy operation, has a standardized production procedures and quality assurance system, standardized pumps are combined to realize a series of parameters of the device, can be widely in the library, archive, ancient buildings, subway, substation, office building, the application of oil-immersed power transformer etc.
Multi - nozzle high pressure water mist nozzle is mainly used for fire fighting system.
The nozzle assembly consists of a nozzle body and nine detachable nozzles.
Each nozzle has an inner core or blade, easy to remove cleaning.
The spray nozzle covers a wide range and distributes evenly.
The small flow resistance loss enables it to save more water in the same flow nozzle.
Multi - nozzle high pressure water mist nozzle is based on unique single micro nozzle technology.
Its unique design allows water to be spewed out at high speeds, turning it into a fine spray that quickly shoots toward the flame.
The large spray Angle and the unique spray mode make the nozzle installation spacing enlarged, the protection area up to 30.25 square meters.
The minimum working pressure of water mist nozzle is 10MPa.
Product advantagesThe water mist nozzle has a wider flow coefficient under the same interface.
The main body and nozzle are combined, easier to check and maintain.
Spray coverage is 7 times that of other nozzles, and can spray to every dead corner.
Water mist nozzles are divided into low pressure, medium low pressure and high pressure, which can meet the needs of equipment in each place.
Water mist nozzle interface size: 1/2, 3/4
2, the structure principle and characteristics of water mist open sprinkler head
The high-pressure fine water mist nozzle is composed of nozzle body, nozzle, nozzle core and filter screen and other parts. After a certain pressure of water enters the nozzle through the filter screen of the nozzle, the pressure water is spewed out from the nozzle hole at a high speed, which generates strong friction with the surrounding air, and the water is torn, thus forming fine water mist spraying along a certain Angle.
The fine water mist sprayed by the high-pressure fine water mist sprinkler belongs to class I fine water mist, Dv0.9≤100μ, high pressure, good diffuse effect, the resident time of water mist after spraying is long, compared with other sprinkler heads, can reduce the intensity of fire extinguishing and fire control spray, less water consumption.
3. Water mist open nozzle uses
High pressure water mist nozzle opening type is high pressure water mist sprinkler system an important component of a, either through tiny droplets cooling fire plume, oxygen, water vapor and may radiate to control fire, fire fighting, usually installed on a fire danger place of production, warehouse, shopping malls, hotels, hospitals, theaters, office buildings, high-rise buildings and garages and other places.
The nozzle should be drooping or horizontal installation, there are two forms of open nozzle and closed nozzle.
If used in ships and corrosive environment, stainless steel nozzle can be provided, which must be processed by separate order.
