Embodiment Construction

[0011] As shown in the figure, the ultra-fine water mist nozzle of the present invention includes a nozzle body 1 with water inlet and outlet. There are 9 nozzle seats 2 arranged radially. Of course, different numbers of nozzle seats such as 1, 3, and 6 can also be installed according to the design requirements of the nozzle to form different protection radii. In the inner cavity of the nozzle seat 2 The screw core 3, the nozzle 4 and the deflector 5 are arranged in sequence, and the water spray channel is formed from the water outlet of the nozzle body 1 through the screw core 3, the nozzle 4 and the deflector 5; the present invention utilizes the elongated hole in the hydraulic principle In the structure of this nozzle, three-dimensional space modeling is adopted, the thickness of the deflector is determined according to the experiment, the aperture and thickness of the nozzle and the thickness of the deflector form a thin-walled hole, and a screw core is installed in the noz...

Abstract

A water-atomizing spray head for extinguishing fire accident in 3D space is composed of a main body with water inlet and outlet, 1-9 nozzle holders arranged radically on said main body, 1-9 water-spraying channels for said 1-9 nozzle holders (one for one) and consisting sequentially screwed core, nozzle and flow guide plate, and a net filter at the water outlet of said main body.

Description

technical field [0001] The invention relates to a special sprinkler head for high-pressure fine water mist for fire extinguishing, in particular to an ultrafine water mist sprinkler head. Background technique [0002] At present, most of the nozzles used in fire protection are fixed pipe network systems, mainly water spray and water spray nozzles, which cannot be applied to mobile fire extinguishing devices, and the fire water nozzles have a large caliber and consume a large amount of water per minute, resulting in water loss greater than fire loss , and cannot be used to fight low flash point liquid fires and electrical fires. Contents of the invention [0003] The object of the present invention is to provide a water-saving ultra-fine water mist nozzle with good fire fighting effect. [0004] To achieve the above object, the present invention can take the following technical solutions: [0005] The ultra-fine water mist nozzle of the present invention comprises a nozzl...
