Fire sprinkler for residential use

Abstract

The invention discloses a fire sprinkler for residential use, comprising a sprinkler body, which is a bucket structure with a water inlet at the upper end thereof; a water guiding body, which is a spiral slice structure and fixedly arranged in the sprinkler body; a plurality of first water outlets, which are evenly distributed at the side wall of the bucket structure in a line; a blocking sleeve, which comprises a plurality of blocking slices of which sides are mutually assembled to a circular cylinder; a plurality of protrusions, which are arranged on the inside walls of multiple blocking slices in a protruding manner; water guiding slots, which are arranged on the inside walls of multiple blocking slices in an embedding manner; a cap body, which is buckled at the bottom part of the bucket structure, and comprises a plurality of moving hinges and fixing hinges aligned alternatively, wherein point ends of the moving hinges are fixedly connected and arranged with the point ends of the fixing hinges through a fusible alloy; multiple second water outlets, which are arranged at a part of bottom part of the bucket structure faced to the moving hinges. The fire sprinkler is long in range, strong in both of penetrating power and flame extinguishing ability; therefore, the fire sprinkler can meet the short-time flame extinguishing demand of the existed residence.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, and specifically discloses a residential fire-fighting sprinkler. 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 the fire hot air flow and reach the surface of the bu...

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.

[0003] Moreover, with the continuous improvement of people's living standards, the number of flammable materials used in interior decoration has increased, and in order to make reasonable use of the interior space, decoration and decoration have been basically done from the ground to the top of the wall. There is a great safety hazard in such interior design. Therefore, it is necessary to install a fire sprinkler with a wide spray area and strong spray penetration
