Abstract
The utility model relates to a water mist fire-extinguishing injector, which is characterized in that the utility model comprises a joint body arranged on the upper portion of an injector body, a filter, the injector body and a mini nozzle, at least two mini nozzles are arranged on the oblique lateral face of the injector body uniformly, communicating with the joint body through a channel in the injector body, the included angle A of the axial trace of the mini nozzle and the axial trace of the injector body is 35 degree to 45 degree and the filter is arranged in the cave between the joint body and the injector body. The utility model has the advantages that the applicable pressure range is extensive, the working pressure range is from 1.8 to 10 million Pascal, the effective section of the water mist injected is far, the water mist still can enter the fire ground to do fire-extinguishing when the height of the equipped injector is over 8 meter, the utility model is suitable for locations with the height from 6 to 10 meters such as an oil engine, a generator and a fuel-gas boiler house and the like and the injector which is arranged as a single layer cuts the cost of installation and material.
Description
Technical field
The utility model relates to a kind of water mist fire-extinguishing nozzle, be fixedly mounted on top of building by total flooding mode individual layer, can put out height less than combustible liquid fire in the building of 10m, be applicable to that building height is the fire-fighting fire extinguishing in places such as the diesel engine, generator, oil-burning gas-fired boiler room of (6-10) m, belongs to the shower nozzle technical field.
Background technology
Atomizing eddy flow device in the fine mist spray head micro nozzle was common in the past helicla flute cyclone and two kinds of patterns of swash plate cyclone, the angle of its nozzle-axis and head body axis is 46 °-60 °, tiltedly the angle of eddy flow plate is 110 °, the whirl hole cone angle of nozzle body is 80 °-120 °, spray holes 10 draw ratios are＜1.2, because the restriction of helicla flute hydrocyclone structure form or swash plate cyclone size is unreasonable, the water smoke range of fine mist spray head is shorter, increase along with the shower nozzle setting height(from bottom), the water smoke speed that more closely faces down is just more little, in the scene of a fire difficult to get access more, thereby the fine mist spray head arranged of individual layer can not put out the combustible liquid fire in the building that highly surpasses 8m effectively, must nozzle layout of sprinkler double-deck or more than the bilayer could put out a fire.This can make expense multiplications such as construction and tubing, and has reduced aesthetics.
Summary of the invention
The purpose of this utility model provides a kind of effective range that increases fine mist spray head, can put out the water mist fire-extinguishing nozzle of the combustible liquid fire in the building that highly reaches 10m when the fine mist spray head individual layer is arranged effectively.
For realizing above purpose, the technical solution of the utility model provides a kind of water mist fire-extinguishing nozzle, it is characterized in that, form by fittings body, filter, head body, micro nozzle, fittings body is located at the top of head body, and at least two micro nozzles evenly are located on the prism of head body, communicate with fittings body by the passage in the head body, the included angle A of micro nozzle axis and head body axis is 35 °-45 °, and filter is located in the inner chamber between fittings body and the head body.
Described micro nozzle is made up of nozzle body and swash plate cyclone, the swash plate cyclone is located in the nozzle body, described swash plate cyclone is made up of flow distribution plate, oblique eddy flow plate, the flow distribution plate both sides have the oblique eddy flow plate juxtaposition of eddy flow groove, the angle of juxtaposition is 85 °-95 °, the whirl hole cone angle C of described nozzle body is 45 °-60 °, and spray holes 10 draw ratios are 1.3-1.8.
The dominant mechanism of fine mist fire-fighting is that deoxygenation suffocates and cools off.Droplet is thin more, thin water smoke vaporize rapid more under the high temperature of the scene of a fire, deoxygenation suffocate and cooling effect strong more, help more putting out a fire, on the other hand, the momentum that drips of mist is more little more for droplet, and range is short more, and it is also difficult more that water smoke enters the scene of a fire, be unfavorable for fire extinguishing more, when the shower nozzle setting height(from bottom) was higher, thin water smoke was drained by the flue gas in the scene of a fire, makes hard fire to put out.This fine mist spray head is by reducing the angle of micro nozzle axis and head body axis, the angle of oblique eddy flow plate, the whirl hole cone angle of nozzle body, the spray holes draw ratio, the thin water smoke that micro nozzle is produced is thicker at axial line place mist droplet particle size, momentum is bigger, mist droplet particle size is thinner around the axial line, the thick droplet drive axial line mist on every side that axial line place momentum is bigger drips and enters the scene of a fire, thereby increasing the droplet momentum, in the time of speed, still keep the strong deoxygenation of thin water smoke to suffocate and cooling effect, when the shower nozzle setting height(from bottom) is higher, still can effectively put out a fire.
The utility model has the advantages that suitable pressure limit is wide, working pressure range is 1.8-10MPa, the thin water smoke effective range of being sprayed is far away, thin water smoke still can enter on the ground the scene of a fire and puts out a fire when the shower nozzle setting height(from bottom) surpassed 8m, be applicable to that building height is the fire-fighting fire extinguishing in places such as the diesel engine, generator, oil-burning gas-fired boiler room of 6-10m, the shower nozzle individual layer is arranged, reduces and installs and Master Cost.
