The present invention relates to fire fighting nozzles having a mist spraying function, which is provided to suppress a fire by spraying fire blocking mist to a fire source using firewater with a 10-20 bar water pressure in a case of a forest fire or an oil fire that is not easy to be suppressed through a large volume of fluid spray. The fire fighting nozzle of the present invention comprises a fire blocking mist spraying part including a large fluid spraying unit at the center of a nozzle part in a nozzle body and a mist nozzle equipped in an outer nozzle part of the large fluid spraying part; and a four-stage water discharging lever equipped in a rear portion of the nozzle body to control a firewater supply in four stages using a four-way valve. Therefore, the fire fighting nozzle of the present invention forms a layer of fire blocking mist resulting in cooling, radiant heat blocking, oxygen rarefaction around a fire source in a case of a fire that is not easy to be suppressed through a large volume of fluid spray since the fire fighting nozzle has the fire blocking mist spraying part at an outer region of the nozzle part, thereby easily and rapidly suppressing an oil fire or a forest fire and protecting firefighters against smoke or the radiant heat. |
