Abstract
Description
Technical Field
[0001] This utility model relates to the field of water mist nozzle technology, and in particular to an industrial fire-fighting water mist nozzle. Background Technology
[0002] A water mist nozzle is a device that breaks down a water stream into fine droplets through a specific structure. Since the nozzle diameter of existing water mist nozzles is generally fixed and relatively small, water passing through the small-diameter orifice helps save water consumption, reduce secondary water loss, and improve atomization. However, when the water quality is poor, the small orifice diameter can easily lead to nozzle clogging and makes maintenance difficult. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the risk of nozzle clogging due to the small orifice diameter when the water quality is poor, and the inconvenience of nozzle maintenance. Therefore, this invention proposes an industrial fire-fighting water mist nozzle.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] Design an industrial fire-fighting water mist nozzle, including a threaded sleeve, on which a nozzle is connected. The nozzle has multiple mounting holes, each containing a nozzle. The nozzles are fixed by a fixing mechanism. Each nozzle has an elastic sleeve fixedly connected to it. The elastic sleeves have cavities, which are adjustable by an adjustment mechanism.
[0006] Preferably, the adjusting mechanism includes a connecting cylinder, which is fixedly connected to the nozzle. A piston abuts against the inner wall of the connecting cylinder, and a threaded post is fixedly connected to the piston. A fixing block is threaded through the threaded post, and the fixing block is fixedly connected to the connecting cylinder. A screw cap is fixedly connected to the threaded post. The connecting cylinder is connected to the cavity through a conduit.
[0007] Preferably, each of the nozzles is provided with a flow guide.
[0008] Preferably, the fixing mechanism includes a screw, the screw being threaded through the nozzle, and the nozzle having a threaded hole, the screw being threadedly connected to the threaded hole.
[0009] Preferably, the screw is a stainless steel screw.
[0010] Preferably, a limiting post is fixedly connected to the fixing block, and the limiting post is located directly below the screw cap.
[0011] Preferably, the limiting post is provided with anti-slip texture.
[0012] The present invention provides an industrial fire-fighting water mist nozzle, which has the following advantages: when it becomes blocked, the air in the cavity is discharged, thereby increasing the inner diameter of the elastic sleeve, so as to discharge the blockage in the elastic sleeve and maintain the nozzle.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Example 1: Refer to Figure 1-4 An industrial fire-fighting water mist nozzle includes a threaded sleeve 1, a nozzle 2 connected to the threaded sleeve 1, multiple mounting holes on the nozzle 2, nozzles 4 in each mounting hole, guide parts 3 on each nozzle 4, and fixed by a fixing mechanism. An elastic sleeve 6 is fixedly connected to each nozzle 4, and a cavity 8 is formed in each elastic sleeve 6. The cavity 8 is adjusted by an adjusting mechanism. As water sprays from the elastic sleeve 6, a spray hole is formed in the inner ring of the elastic sleeve 6. When blockage occurs, air is expelled from the cavity 8, thereby increasing the inner diameter of the elastic sleeve 6 to expel the blockage and facilitate nozzle maintenance.
[0020] The adjustment mechanism includes a connecting cylinder 9, which is fixedly connected to the nozzle 2. A piston abuts against the inner wall of the connecting cylinder 9, and a threaded column 7 is fixedly connected to the piston. A fixing block 12 is threaded through the threaded column 7 and fixedly connected to the connecting cylinder 9. A screw cap 10 is fixedly connected to the threaded column 7. The connecting cylinder 9 is connected to the cavity 8 through a conduit. By rotating the screw cap 10, the threaded column 7 will be rotated, which will drive the piston to move and change the amount of air in the cavity 8, thereby changing the inner diameter of the elastic sleeve 6. When the water quality is poor or blocked, the inner diameter is enlarged, and when the water quality is good, the orifice diameter is reduced to improve the atomization efficiency.
[0021] Example 2: Refer to Figure 1-4 As another preferred embodiment of this utility model, based on embodiment 1, the fixing mechanism includes a screw 5, which is a stainless steel screw. The screw 5 is threaded through the nozzle 4. The nozzle 2 has a threaded hole, and the screw 5 is threadedly connected to the threaded hole. The screw 5 is used to disassemble the nozzle 4 and replace it.
[0022] Example 3: Reference Figure 1-4 As another preferred embodiment of this utility model, based on embodiment 2, a limiting post 11 is fixedly connected to the fixing block 12. The limiting post 11 is located directly below the screw cap 10. The limiting post 11 is provided with anti-slip texture. By using the limiting post 11 to limit the position of the screw cap 10, the maximum amount of air squeezed into the cavity 8 can be adjusted, and the minimum inner diameter of the elastic sleeve 6 can be controlled to prevent the amount of water passing through from being too small.
[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
