Description

Technical Field

[0001] The invention relates to the technical field of fire sprinkler nozzles, and in particular to a highly efficient and easy-to-maintain rotary fire sprinkler nozzle. Background Art

[0002] Fire sprinkler is a key component of automatic sprinkler fire extinguishing device designed for various indoor and outdoor office buildings, commercial streets, factories, warehouses and shopping malls. It uses water flow to impact the splash plate to achieve uniform water spraying and fire extinguishing. When the temperature in the installation area rises to a specific threshold due to the fire, the fusible alloy in the sprinkler will melt or the glass beads will burst, thereby automatically opening the sprinkler. Under the action of the fire pipe network pressure, water flows through the splash plate above the sprinkler and sprays evenly around, which is more effective in controlling the fire and extinguishing the fire. The existing defect is that since the splash plate itself is fixed, the water mist formed after the water flow impacts the splash plate has a certain spraying blind area, which has an adverse effect on efficient fire extinguishing, and the water consumption increases, posing a serious threat to the safety of life and property of personnel. Summary of the invention

[0003] The invention provides a highly efficient and easy-to-maintain rotary fire-fighting upper upright sprinkler head, so as to overcome the disadvantage that the existing fire-fighting sprinkler head has a spray blind area caused by the fixed splash plate, which reduces the fire extinguishing and fire control effects.

[0004] The technical solution of the present invention is: A highly efficient and easy-to-maintain rotary fire-fighting upper upright sprinkler comprises: a rotary water splashing plate 2, which is sleeved on a short fire-fighting vertical pipe 1 and movably supported by the lower surface of a support nut 3 screwed on the top of the short fire-fighting vertical pipe; a right bracket 201 and a left bracket 202 of the rotary water splashing plate 2 are fixedly connected to the upper ends of a water splashing plate 205, and a water splashing plate drainage groove 203 and a water splashing plate automatic stop 204 are arranged on the water splashing plate 205; an adjusting screw 7 is arranged at the center of the water splashing plate; a sealing adjustment rubber ring 4 and a water baffle 5 are arranged between the supporting nut 3 and the short fire-fighting vertical pipe 1; the water baffle 5 is supported downward by a temperature-sensitive glass bead 6, and the temperature-sensitive glass bead is supported downward by the adjusting screw 7 on the water splashing plate 5; and the force applied to the temperature-sensitive glass bead 6 is adjusted by the coordinated action of the adjusting screw 7 and the sealing adjustment rubber ring 4.

[0005] Furthermore, when the fire sprinkler does not operate and the triggered temperature-sensitive glass beads are intactly supported, the adjusting screws 7, temperature-sensitive glass beads 6, water baffles 5 and sealing adjustment rubber rings 4 on the splash plate 205 jointly seal the fire pressure water in the fire short riser 1.

[0006] Furthermore, when the fire sprinkler is triggered, the temperature-sensitive glass beads 6 burst, and the pressurized water in the fire short riser 1 rushes upward, breaks open the water baffle 5, and further rushes into the splash plate 205. Part of the pressurized water directly passes through the splash plate 205 and the splash plate drainage groove downward to extinguish the fire, and part or all of the pressurized water will rush into the splash plate automatic block 204 at the same time. The splash plate automatic block 204 rotates under the impact of the water flow, and the rotation of the splash plate automatic block 204 drives the splash plate 2 to rotate as a whole, and the splash plate drainage groove 203 follows the rotation at the same time, achieving a full coverage spraying effect with uniform water flow distribution.

[0007] Furthermore, a limit stop is provided inside the support nut 3, and the limit stop limits the extent to which the support nut can be screwed into the fire riser.

[0008] Furthermore, after the nozzle has been over-sprayed, only the temperature-sensitive glass beads 6, the sealing adjustment rubber ring 4 and the water baffle 5 need to be replaced, which greatly reduces the replacement cost and improves the replacement efficiency.

[0009] Furthermore, the temperature-sensitive glass beads 6 may also be replaced by temperature-sensitive fuse devices. BRIEF DESCRIPTION OF THE DRAWINGS
