Embodiment 1

[0049] For the structure of each part, see Figure 1~6 , including the fire sprinkler base 19 of the arc-shaped nozzle, the gasket 25, the sprinkler core 10 and the sprinkler cap 27. In this example, the connection target is the water inlet pipe with an inner diameter of 10mm. The nozzle base is made of stainless steel with a thickness of 2mm. The diameter of the cylinder 22 is 28mm, and the radius of the cylindrical missing body 23 is 19mm. The central cylindrical boss of the base has a diameter of 20mm and a height of 2mm. The fins 21a and 21-b are 5mm long and 0.5mm thick; a 2mm threaded hole 24 is drilled in the center of the base 20, and a 1mm threaded hole 20 is also drilled around it. The washer is made of stainless steel. The inner diameter of the main ring part is 20mm, the outer diameter is 28mm, and the height is 2mm; the angle between the two ends is 120 degrees, and the cut surface size of the end is 2mm×2mm. Set 1mm threaded holes 1mm away from both ends of the ...

Embodiment 2

[0053] The inner diameter of the fire water inlet is 20mm, which is the equal magnification of some components in Example 1. For example, the diameter of the bottom surface of the nozzle core cone is 40mm, the height is 20mm, the radius of the major axis of the curved guide fins 15-a and 16-a is 12mm, the radius of the minor axis is 10mm, and the radius of the curved guide fins 15-b and 16-b The radius is 12mm. Wherein the height and thickness of the fins remain unchanged, while other dimensions are correspondingly expanded in equal times. The main changes of other components are as follows: the thickness of the base cylinder is 2mm, the diameter is 48mm, the height of the round platform is 2mm, and the diameter is 40mm. The cylindrical missing body 23 has a radius of 29mm and a thickness of 2mm. The width of the washer is 4mm, the diameter of the inner circle is 40mm, the diameter of the outer circle is 48mm, the height is 2mm, and the diameter of the circle where the threa...

Abstract

The invention provides a centrifugal diversion fire-fighting water curtain sprinkler head with an arc-shaped nozzle. The centrifugal diversion fire-fighting water curtain sprinkler head comprises a sprinkler head case and a sprinkler head core, wherein the sprinkler head case consists of a base, a gasket and a conical cap, a main body of the sprinkler head core is a cone, diversion fins are arranged on the outlet side and the back side of the main body of the sprinkler head core, the sprinkler head core is fixedly connected with the base of the sprinkler head case through a bolt, the conical sprinkler head core is arranged in a cavity in the sprinkler head case along with a fire-fighting water inlet center line, the central line of the sprinkler head core is coincident with that of a water pipe, the semi-vertical angle of the cone is 45 degrees, the outlet side of the main body of the sprinkler head core is provided with the straight diversion fins, and the included angles of the projections of the straight diversion fins on bottom surfaces are 60 degrees. The centrifugal diversion fire-fighting water curtain sprinkler head with the sprinkling design overcomes the defect that the conventional sprinkler head cannot be effectively applicable to fire disasters on vertical wall surfaces, and is improved and designed according to fire disasters occurring in current high-rise buildings. The sprinkler head can effectively restrain the spreading of fire disasters on external walls of the high-rise buildings so as to reduce personal casualties and property loss brought by the fire disasters of the high-rise buildings.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, and in particular relates to a centrifugal-guided fire-fighting water curtain sprinkler head with an arc-shaped nozzle, which is specifically a fire-extinguishing sprinkler head of a mechanical fluid spray fire extinguishing device. Background technique [0002] In recent years, due to the frequent occurrence of high-rise building fire accidents, it has brought huge losses to people's personal and property safety. The burning of the outer walls of high-rise buildings is often one of the direct causes of the rapid spread of fire to higher floors and serious accident consequences. [0003] The control measures for the fire spread on the vertical wall mainly include two aspects: the fire extinguishing agent covers the surface of the combustibles to isolate the air; the temperature of the surface of the combustibles is reduced to extinguish the flame. This places new demands on the w...
