Fire-fighting long-distance spraying power-assisted nozzle and application method thereof

Abstract

The invention discloses a fire-fighting long-distance spraying power-assisted nozzle and an application method thereof, and belongs to the field of fire-fighting nozzles. The fire-fighting long-distance spraying power-assisted nozzle comprises a nozzle body, wherein a threaded connecting end is fixedly connected to the upper end of the nozzle body, and a splash disk is arranged at the lower end ofthe nozzle body. According to the fire-fighting long-distance spraying power-assisted nozzle and the application method thereof, through the arrangement of a power-assisted diffusion ring, the power-assisted diffusion ring can be controlled to diffuse when the fire spreading temperature is too high, and a plurality of superposed diffusion plates on the power-assisted diffusion ring further diffuse and unfold under the action of centrifugal force, so that on one hand, the area of water spraying and the water spraying amount per unit time are increased, on the other hand, the water spraying range is also increased under the action of centrifugal force, and the effect of power-assisted water spraying is achieved; and meanwhile, the water spraying effect of a nozzle in the prior art is matched, and the double water spraying can effectively improve the suppression effect of the fire-fighting nozzle on fire spread, so that more reaction time is gained for firefighters, and the safety is obviously improved.

Description

technical field [0001] The invention relates to the field of fire-fighting nozzles, more specifically, to a long-distance spray booster nozzle for fire-fighting and its usage method. Background technique [0002] The fire sprinkler is used in the fire sprinkler system. When a fire occurs, the water is sprayed out through the sprinkler splash plate to extinguish the fire. It is divided into a pendant sprinkler, a vertical sprinkler, a common sprinkler, a side wall sprinkler, etc. . [0003] The pendant sprinkler is the most widely used sprinkler. It is installed on the branch pipe of the water supply. The shape of the sprinkler is parabolic, and 80-100% of the total water is sprayed to the ground. To protect rooms with suspended ceilings, sprinkler heads should be arranged under the suspended ceiling, and drooping sprinklers or ceiling-mounted sprinklers should be used. [0004] In the event of a fire, the existing fire sprinklers have a certain range of spraying water and ...

AI Technical Summary

Problems solved by technology

[0004] In the event of a fire, the existing fire sprinklers have a certain range of spraying water and a certain amount of sprayed water. When the fire spreads, the amount of water sprayed cannot be increased synchronously. It is difficult to suppress the fire in time, resulting in faster fire spread. When the firefighters rush to the scene to fight the fire, it is more dangerous and more difficult
