A fire automatic sprinkler with dust removal function

Abstract

The invention discloses a fire-proof automatic sprinkler with dust removal function, which belongs to the technical field of fire-fighting, and comprises a valve seat, the lower surface of which is fixedly connected with the upper surfaces of two support frames, The other end of the water spray pipe is fixedly connected to the outer surface of the same water spray pipe, and the upper surface of the water spray pipe is provided with a heat sensitive element. The fire automatic sprinkler with dust removal function can stop when the splash plate is turned to a suitable angle by setting bearings, rotating shafts, threaded cylinders, fixed sleeves, adjusting rings, first pin shafts and second pin shafts. Turning the turntable makes the sprinkler effectively guarantee the stability of the angle of the splash plate, and because the angle of the splash plate can be adjusted only by turning the turntable, the adjustment difficulty of the sprinkler is effectively reduced, so that The sprinkler can adjust the splash plate and the splash pan according to different installation locations and requirements, thereby improving the applicability of the shower.

Description

technical field [0001] The invention belongs to the technical field of fire protection, in particular to a fire automatic sprinkler with dust removal function. Background technique [0002] Fire-fighting and fire-proof automatic sprinkler heads are used in fire-fighting sprinkler systems. When a fire occurs, water is sprinkled through the fire-resistant automatic sprinkler head splash plate to extinguish the fire. Currently, it is divided into drooping wine sprinklers, vertical sprinklers, and ordinary sprinklers. , side wall type sprinklers, etc. When a fire occurs, the fire-fighting water is evenly sprinkled through the fire-proof automatic sprinkler head to control the fire in a certain area. Compared with the side wall type, the pendant type sprinkler is the most widely used type of sprinkler, which is installed on the water supply branch pipe. The shape of the sprinkler is parabolic, and 80-100% of the total water is sprayed to the ground to protect the room with a susp...

AI Technical Summary

Problems solved by technology

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a fire-proof automatic sprinkler with dust removal function, which solves the problem that most of the current fire-proof and fire-proof automatic sprinklers are often not equipped with protective mechanisms on the surface when they are in use. As a result, when used indoors, it is easy to cause damage to the glass liner in the fire-proof automatic sprinkler head. At this time, the fire-proof automatic sprinkler head will sprinkle water outward, which will not only spray water stains on the ground, but also easily cause pedestrians passing by. Slip, and because there are many types of sprinklers, in order to make the sprinklers more consistent with the actual use in the selection process, when the staff needs to choose the type of sprinkler, it is necessary to select the type of automatic fire sprinkler, but Due to the relatively simple structure of most nozzles, it is difficult to adjust according to the actual use situation, resulting in the problem that the applicability of the nozzle is greatly limited
