Embodiment 1

[0019] Disclosed is a liquid fire extinguishing agent atomizing sprinkler head. A plurality of atomizing nozzles are arranged around the sprinkler head, and a plurality of pipe-jet spray bodies with contracted section are arranged in the center.

[0020] The atomizing nozzle makes the flowing liquid rotate, and after the outlet, it is broken by friction with the air and atomized to produce a spray fluid mist field.

[0021] The liquid flowing through the pipe jet spray body is sprayed from its nozzle at a higher speed to form a high-speed jet, which passes through the atomizing nozzle to generate a spray fluid mist field. When it rubs against the air, it breaks and atomizes in a farther area to produce a spray Fluid fog field.

[0022] Atomizing sprinkler head of the present invention such as figure 1 As shown, it consists of four parts: nozzle seat 1, nozzle seat 2, nozzle core 3 and nozzle cover 4; nozzle core 3 is installed in nozzle seat 2, nozzle seat 2 is installed in n...

Embodiment 2

[0028] See attached Figure 1 to Figure 5 As shown, the liquid fire extinguishing agent atomizing sprinkler head of the present invention comprises four parts such as nozzle seat 1, nozzle seat 2, nozzle core 3 and nozzle cover 4; Installed in the shower head seat 1, the shower head cover 4 is installed on the top of the shower head seat 1.

[0029] The nozzle seat 1 is as figure 2 As shown, it is a hollow frustum-shaped rigid body, one end is an M20 internal thread 13, which is externally connected to the liquid delivery pipeline, and the other end is an internal concave platform 12 with a diameter of 36mm and a depth of 13mm, which is used to install the nozzle seat 2, and the size is an external thread of M42 14 is connected with the nozzle cover 4, and is used for fixedly installing the nozzle seat 2; the nozzle seat 2 is as image 3 As shown, it is a stainless steel cylinder with a diameter of 36 mm and a height of 13 mm. A shrinkage hole 6 with a diameter from 3 mm to...

Embodiment 3

[0035] On the same nozzle as in Example 1, the center of the nozzle seat 2 is evenly opened with 4 shrinking holes 6 with a diameter ranging from 3 mm to 1.5 mm, and 5 belts are evenly arranged on a concentric circle with a diameter of φ24 around the holes 6. The spray hole 5 of the M8 internal thread is used for installing the nozzle core 3 . This type of nozzle can spray more liquid in use and produce a stronger fog field.

Abstract

The invention provides a liquid fire extinguishing agent atomizing and spraying head. A plurality of atomizing nozzles are distributed on the periphery of a spraying head; a plurality of area reduction type pipeline jet injection bodies are distributed at the center of the spraying head; the atomizing nozzles rotate flowing-though liquid and a jet fluid fog field is generated by rubbing the discharged fluid with air and then crushing and atomizing; the liquid which flows through the pipeline jet injection bodies is sprayed out from the nozzles at a high speed so as to form a high-speed jet flow; the high-speed jet flow penetrates through the atomizing and spraying head to generate the jet fluid fog field; and after the liquid is rubbed with air, the liquid is crushed and atomized in a farther region to form the jet fluid fog field. The atomizing nozzles of the spraying head of the fire extinguishing agent disclosed by the invention generate a jet liquid fire extinguishing agent fog field, and a pipeline jet injection liquid fire extinguishing agent is crushed and atomized in the farther region to form a jet liquid fire extinguishing agent fog field; and the two liquid fog fields are connected to form a banana-shaped liquid fire extinguishing agent fog field.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting equipment, and in particular relates to an atomized sprinkler head for liquid fire-extinguishing agent. Background technique [0002] In order to extinguish fires safely and efficiently, the present invention proposes a liquid fire extinguishing agent atomization spray head capable of spraying and producing a banana-like shape. The fire extinguishing agent sprayed in the center is fast, and when installed on a hand-held fire extinguisher, the spraying distance is long and the atomization effect is good. , High fire extinguishing efficiency. When the sprinkler head is sprayed from top to bottom, the height of the sprinkler head arrangement is increased, the sprayed fire extinguishing agent has a large coverage area, strong penetrating power, easy to penetrate the fire plume, and good fire extinguishing effect. The atomized fire extinguishing agent produced by the atomized nozzle of the exist...
