Abstract
The utility model relates to a bumping fine water mist spray head which is composed of a spray head base and a nozzle, wherein the nozzle is connected with the spray head base through screw threads, or the nozzle and the spray head base are integrated into a whole. The inner chamber of the spray head base is communicated with the inner chamber of the nozzle. The spout of the nozzle is a frustum-shaped spout which is communicated with the inner chamber of the nozzle through two to twelve inclined holes, and the central lines of all the inclined holes intersect at one point. Because the utility model spays a plurality of water currents which mutually bump at the intersecting point, even fine water mist whose grain diameter is from 100 mu m to 1000 mu m is formed, and the fire extinguishing ability of the fine water mist can be improved. The utility model has simple structure, easy production and low cost, and is suitable for extinguishing fire of Class A, class B and Class C.
Description
Technical field:
The utility model relates to the fine mist spray head that a kind of fire-fighting fire extinguishing is used, particularly a kind of impacting type fine mist spray head.
Background technology:
Water Mist Fire Extinguishing Technique is owing to make water as extinguishing chemical, and is pollution-free, cost is low, and water-saving, good extinguishing effect.Fine water mist fire-extinguishing system applies to every field abroad gradually at present, comprising: electronic equipment fire fire extinguishing protection, as the fire extinguishing protection such as appliance fire of fire and modern large enterprise in computer floor fire, the aeronautics and space aircraft cabin; Be applicable to liquid (category-B) fire, as the aspects such as power cabin gas turbine, subway tunnel, sealing chamber flammable liquid apotheca and military combat tank of boats and ships, Water Mist Fire Extinguishing Technique shows wide application prospect; Water Mist Fire Extinguishing Technique also has been widely used in puts out the category-A fire, as: cabin aisle, public space dwelling house, ancient building and library etc.
Water Mist Fire Extinguishing Technique is started late at home, but has obtained increasing attention, and that uses at home at present more is external product.Therefore developing the Water Mist Fire Extinguishing Technique with independent intellectual property right has been instant task.This key technology wherein is exactly a fine mist spray head, and its atomization has directly determined the extinguishing ability of fine water mist fire-extinguishing system.The nozzle of existing fine mist spray head is because its structure more complicated, the processing cost height, and the water smoke particle diameter is thicker, and operating pressure is higher, has limited the development of fine water mist fire-extinguishing system.
The utility model content:
The purpose of this utility model is to provide a kind of impacting type fine mist spray head, collides mutually by its each nozzle ejection multi-strand flow, forms water smoke uniformly.Can design the water smoke that produces different-grain diameter at different fire extinguishing objects, average particle size range is between 100 μ m～1000 μ m.
The utility model adopts following technical proposals in order to achieve the above object:
A kind of impacting type fine mist spray head, constitute by nozzle boss and nozzle body, nozzle body and nozzle boss are by being threaded, perhaps nozzle body and nozzle boss are integral, the inner chamber of nozzle boss communicates with the inner chamber of nozzle body, the spout that it is characterized in that described nozzle body is a taper type spout, communicates with the inner chamber of nozzle body by 2～12 inclined holes, and the center line of all inclined holes is intersected in a bit.
It is 50 °～170 ° that the center line of above-mentioned inclined hole is intersected in any formed tapering, and the diameter of described inclined hole is 0.2～5 millimeter.
The taper type tapering of the taper type spout of above-mentioned nozzle body is 15 °～160 °, and the port of export diameter of described taper type spout is 2～50 millimeters.
Described nozzle body on the above-mentioned nozzle boss has 1～20, one of them nozzle body centerline is on the position of center line of nozzle boss, the center line of remaining nozzle body is that axis becomes the axial symmetry taper circumferentially uniform with the nozzle boss center line, and the tapering of its taper is 10 °～270 °.
The utility model compared with prior art, have following conspicuous substantive distinguishing features and advantage: the spout of the nozzle body in the utility model is the taper type spout, communicate with the nozzle body inner chamber by a plurality of inclined holes, all inclined hole center lines are intersected in a bit, then the multi-strand flow by a plurality of inclined hole ejections clashes into mutually at the joint place, form uniformly thin water smoke, the water smoke average grain diameter is 100 μ m～1000 μ m, can improve the fine mist fire-fighting ability.The utility model is simple in structure, is easy to make, and cost is low, is applicable to put out category-A, category-B and C class fire.
Description of drawings:
Accompanying drawing is the structural representation of an embodiment of the utility model.
The specific embodiment:
A preferred embodiment of the present utility model is: referring to accompanying drawing, this impacting type fine mist spray head is made of nozzle boss 1 and nozzle body 2, nozzle body 2 and nozzle boss 1 are by being threaded, the inner chamber 4 of nozzle boss 1 communicates with the inner chamber 3 of nozzle body 2, the spout that it is characterized in that described nozzle body 2 is a taper type spout 5, communicate with the inner chamber 3 of nozzle body 2 by 2～12 inclined holes 6, the center line of all inclined holes 6 is intersected in a bit.It is 50 °～170 ° that the center line of described inclined hole 6 is intersected in any formed taper theta, and the diameter d of described inclined hole 6 is 0.2～5 millimeter.The taper type tapering β of the taper type spout 5 of described nozzle body 2 is 15 °～160 °, and the port of export diameter 7 of described taper type spout 5 is 2～50 millimeters.Have 1～20 on the above the nozzle body 2 of described nozzle boss 1, one of them nozzle body 2 centerline is on the position of center line of nozzle boss 1, the center line of remaining nozzle body 2 is that axis becomes the axial symmetry taper circumferentially uniform with nozzle boss 1 center line, and the tapering α of its taper is 10 °～270 °.
Another embodiment of the present utility model is: present embodiment and the foregoing description are basic identical, and institute's difference is: nozzle body 2 and nozzle boss 1 are integral.
