Assembly type automatic rotating spray head

Abstract

The invention discloses an assembly type automatic rotating spray head. The assembly type automatic rotating spray head comprises a water inlet pipe connected with a fire water pipeline, a flow guidecover fixed to a water inlet pipe, a flow guide impeller fixed to the water inlet pipe through a bearing and located below the flow guide cover, a porous spray head communicating with the water inletpipe through threads, a jet nozzle arranged on the lower part of the flow guide cover, a flow guide port formed in the water inlet pipe and communicating with an inner channel of the water inlet pipe,and a flow guide pipe used for communicating the flow guide port with the jet nozzle. According to the assembly type automatic rotating spray head, through arrangement of the jet nozzle and the flowguide impeller, water flow is sprayed out through the jet nozzle to generate impact force on the flow guide impeller, the flow guide impeller is promoted to rotate, the flow guide impeller rotates ata high speed, the water flow sprayed out of the jet nozzle and the water flow sprayed out of the porous spray head are scattered and atomized, and a solid conical spray is formed through the flow guide cover, so that the atomizing radius of water mist is greatly increased, the fire extinguishing radius is increased, the fire extinguishing efficiency of the spray head is improved, and the life andproperty safety of people is ensured.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to an assembled automatic rotating sprinkler head. Background technique [0002] The sprinkler is a sprinkler device that can sprinkle water according to the designed sprinkler shape and flow rate under working conditions, and is an important part of the fire extinguishing system. Existing ordinary fire sprinklers usually have poor water distribution performance due to their own structural limitations or differences in use, and the atomization angle is generally less than 150°. When used in stadiums, warehouses, shopping malls and other tall and clear places, it is often difficult to meet the needs of fire extinguishing , most of the existing rotary nozzles benefit from hydraulic circulation and aerodynamic principles, rotate and distribute large water droplets, and form less water mist. When applied to fire extinguishing in traffic tunnels and protection and cooling...
