Water mist nozzles are a common type of nozzle, primarily used to spray water mist for cooling, humidification, and cleaning. The principle of a water mist nozzle is to use centrifugal agitation or impact to break down a stream of water into fine droplets, which are then sprayed out. It serves as a component of water-cooling and fire extinguishing equipment.
On September 1, 2014, the newly revised "Implementation Rules for Compulsory Certification of Fire Protection Products" came into effect, including water mist nozzles in the scope of mandatory certification. Relevant testing standards include GA 33-1992 and GB 5135.3-2003.
High-pressure fine water mist fire extinguishing systems are gradually becoming an important development direction due to their high efficiency and water-saving characteristics. High-pressure fine water mist nozzles are an important component of high-pressure fine water mist fire extinguishing systems.
On February 11, 2025, Yangtian Technology obtained a patent entitled "A Fine Water Mist Nozzle," authorized by publication number CN 222428301 U. This patented technology uses multiple intersecting baffles at the nozzle inlet channel to initially disperse the inhaled water flow, and then uses rotating blades at the nozzle opening to further break up the water flow at the end, thereby producing an extremely fine water mist that can meet the needs of some special applications.
