The high-pressure water mist closed nozzle is composed of nozzle shell, nozzle, nozzle core and filter. The spray droplet diameter can reach Dv0.5 less than 200μm and Dv0.99 less than 400μm, which belongs to the Class I water mist level. Compared with other fire sprinklers, high-pressure water mist closed sprinklers have obvious advantages such as lower spray intensity for fire extinguishing and fire control, environmental protection, energy saving and less water consumption.

High-pressure water mist closed nozzle customization:

In addition to conventional models and parameters, our company has the ability to design and produce other forms of high-pressure water mist closed nozzles. Customers can provide structural types, flow coefficients and materials for customization. Customization of high-pressure water mist closed nozzles requires at least the following information:

● Nozzle structure type, such as appearance size, thread, structure, etc.;

●Media;

● Flow coefficient;

● Performance requirements, such as droplet diameter, range, spray angle, installation parameters, etc.;

● Minimum and maximum work pressure;

● Application place and working environment;

● Material;

● Glass sphere parameters.

Types of high-pressure water mist closed nozzles:

There are three common structural types of high-pressure water mist closed nozzles: A series, B series and C series. Among them, A series is a closed ordinary frame, that is, the nozzle is embedded; B series is a closed protruding hole, that is, the nozzle is protruding; C series is a closed direct-fire frame.

High-pressure water mist closed sprinkler application areas:

Fire-fighting high-pressure water mist closed nozzles are used to extinguish, suppress, control fire, control temperature and reduce dust in the following fire scenarios:

Category A: combustible solid fires in bookstores, archives, cultural relics libraries and other places;

Category B: flammable liquid fires in hydraulic stations, oil-immersed power transformer rooms, lubricating oil warehouses, turbine oil warehouses, diesel generator rooms, oil-fired boiler rooms, fuel-fired direct-fired engine rooms, oil switch cabinet rooms and other places.
