Abstract

The invention relates to the technical field of fire-fighting equipment, and discloses a fire-fighting spray head capable of adjusting a spraying range. The spray head comprises a roof wall, the bottom end of the roof wall is fixedly connected with a spray head main body, the bottom end of the spray head main body is movably connected with a valve plate, the bottom end of the valve plate is movably connected with a glass ball, the glass ball is filled with a colored liquid, the bottom end of the colored liquid is movably connected with a taper sleeve, the bottom end of the taper sleeve is fixedly connected with a water splashing disc, a flow guiding groove is formed in the surface of the water splashing disc, and the two ends of the water splashing disc are movably connected with rotatingshafts and movably connected with supports through the rotating shafts. According to the spray head, the inclined flow guiding groove is formed in the water splashing disc, so that when fire-fightingwater passes through the flow guiding groove, the water splashing disc is pushed to rotate, the supports and positioning blocks are driven to rotate, the sleeve moves upwards to a flat thread sectionalong the axis of the spray head main body, the rotating speed of the water splashing disc is increased, and the spraying area of the fire-fighting water is increased.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a fire-fighting sprinkler head with an adjustable sprinkling range. Background technique [0002] The fire sprinkler head is a key component of the automatic sprinkler system. It is used to detect fire and control or extinguish the fire through automatic spraying. When the fire occurs, the surrounding temperature rises rapidly. The glass ball will burst, and the air cushion installed in the water nozzle will be washed away, and the pressure water will be sprayed out quickly, completing the fire detection and fire extinguishing process. [0003] However, the installation of the fire sprinkler head is fixed, so that the sprinkler head can only cool down and extinguish the fire at the bottom of the sprinkler head when sprinkling water. Although the existing fire sprinkler head is equipped with a splash plate to change the shape of the water flow and increase the spra...
