Problems solved by technology

However, the fire sprinklers in the prior art, either due to the use of impact type water spray, or because of their high rotational speed, cause the water atomization phenomenon of the spray nozzle to be very serious, and the water spray particles are small, and the water particles are smaller. The smaller the ability of penetrating the fire hot air to reach the surface of the burning object, the lower the fire extinguishing ability, and the lower the installation height of the sprinkler head during engineering installation, so that it has certain limitations in use.

Embodiment 1

[0019] The top of the lower body 1 is connected with the upper cover 2 through threads, and the interior of the lower body 1 is provided with a plurality of rectifying water channels, the water outlet of the rectifying water channels is connected with the torque adjustment nozzle 3 through the inner card, and the top of the rectifying water channel communicates with one end of the water inlet pipe 5; The other end of the water inlet pipe 5 stretches out from the loam cake 2; a bearing 4 is arranged between the water inlet pipe 5 and the loam cake 2, so the water inlet pipe 5 and the loam cake 2 can rotate relatively.

Embodiment 2

[0021] Balls are arranged between the water inlet pipe 5 and the upper cover 2, and other structures are the same as in the first embodiment.

[0022] The working principle of the present invention is described as follows

[0023] After the water flow with a certain pressure enters the water inlet pipe, it is sprayed out through the rectifying water channel and the torque adjustment nozzle. If the torque adjustment nozzle is adjusted to a suitable angle along the center line of the nozzle, under the impact of the water flow, it will rotate along the center line of the water inlet pipe. Torque makes the lower body rotate, the greater the torque, the higher the rotation speed. The advantage of rotating water spray is to spray water evenly within the range to be protected. The speed of the nozzle when rotating the water spray determines the size of the water spray particles. The higher the speed, the more serious the atomization phenomenon, the smaller the water spray particles,...

Abstract

The invention relates to a fire control sprayer with adjustable water spraying particles, belonging to the technical field of fire control equipment. The top of the lower sprayer is connected with an upper cover, a rectification water passage is arranged in the lower sprayer, the water outlet of the rectification water passage is connected with a nozzle, the top of the rectification water passageis communicated with one end of a water inlet pipe, and the other end of the water inlet pipe extends from the upper cover. The sprayer can rotate both fast and slowly when the sprayer is used for spraying water, thereby enhancing the mobility of the fire control sprayer and enlarging the serviceable range.

Description

technical field [0001] The invention relates to a fire-fighting nozzle, in particular to a fire-fighting nozzle with adjustable water spray particles, which belongs to the technical field of fire-fighting equipment. Background technique [0002] The automatic sprinkler system of the fire sprinkler is to automatically spray water to extinguish the fire when a fire occurs. It has the fire prevention effect of blocking flame penetration, heat absorption and smoke isolation, and can carry out early fire extinguishing for high-risk fires. Therefore, many Large factories, workshops, halls, theaters and other buildings are equipped with fire sprinklers. However, the fire sprinklers in the prior art, either due to the use of impact type water spray, or because of their high rotational speed, cause the water atomization phenomenon of the spray nozzle to be very serious, and the water spray particles are small, and the water particles are smaller. The smaller the ability to penetrate...
