Times.
It should be understood that in other embodiments, copper mesh is provided with the fourth hole 131 of Metallic Nozzle At The Ingot 13, with by the copper
Silk screen breaks up fire extinguishing material so that the fire extinguishing material of output is in atomization shape.Certainly, except being provided with copper in fourth hole 131
Silk screen, can also be set in fourth hole 131 at least two cross one another and diameter smaller (such as 1,2,3 millimeters) copper
Bar, the fire extinguishing material that will can be also exported from fourth hole 131 by the copper bar is broken up.
Further, Metallic Nozzle At The Ingot 13 is provided with the 3rd sealing ring 123 with the junction of nozzle metab 12, to strengthen gold
The sealing that both category shower nozzle 13 and nozzle metab 12 are connected.
Metal rotation rod 14 is cylindrical, and metal rotation rod 14 is rotatably disposed in the 5th chamber of the inside of Metallic Nozzle At The Ingot 13
In body 133.Helicla flute 143 is wherein provided with metal rotation rod 14, helicla flute 143 prolongs from the bottom spiral of metal rotation rod 14
Extend the top of metal rotation rod 14.
In the present embodiment, the width of the depth of helicla flute 143 and helicla flute 143 is equal, can so keep being exported
Fire extinguishing material it is uniform.Further, the width of helicla flute 143 is 2 times of the diameter of fourth hole 131, is so enabled to
Fourth hole 131 by the fire extinguishing material output in the 5th cavity 133, will not cause that excessive fire extinguishing material is retained in the 5th in time
In cavity 133.
In the present embodiment, the inwall of the 5th cavity 133 of Metallic Nozzle At The Ingot 13 is provided with an article pit, when metal rotation rod 14 is received
Hold when in the 5th cavity 133, metal rotation rod 14 can't seal the 5th cavity 133, can be ventilated by this pit, with
Conveying fire extinguishing material, to drive metal rotation rod 14 to rotate.
Specifically, metal rotation rod 14 includes being housed in the swivel head 142 of the 5th cavity 133 and is connected with swivel head 142
Support column 141, swivel head 142 and support column 141 be cylindrical, and the diameter of swivel head 142 is bigger than the diameter of support column 141,
The diameter of swivel head 142 is equal to or slightly less than the diameter of the 5th cavity 133, and helicla flute 143 is close to support column from swivel head 142
141 bottom is spirally extended to top of the swivel head 142 away from support column 141.
It is worth noting that, the rotary speed of metal rotation rod 14 is exported with the fourth hole 131 from Metallic Nozzle At The Ingot 13
Fire extinguishing material atomizing effect it is relevant, i.e., when the rotary speed of metal rotation rod 14 is faster, from the four-way of Metallic Nozzle At The Ingot 13
The atomizing effect of the fire extinguishing material that hole 131 is exported is better, when the rotary speed of metal rotation rod 14 is slower, from Metallic Nozzle At The Ingot 13
Fourth hole 131 exported fire extinguishing material atomizing effect it is poorer.Therefore, in other embodiments, the width of helicla flute 143
Degree is in gradually to become away from the direction at the top of support column 141 near the bottom of support column 141 to swivel head 142 along swivel head 142
Small setting, and helicla flute 143 depth along swivel head 142 near support column 141 bottom to swivel head 142 away from support column
In setting is become larger, so setting can accelerate the rotary speed of metal rotation rod 14 in the direction at 141 top, because fire extinguishing
When material enters five cavitys 133, most fast contact is width than larger helicla flute 143, under the effect of the pressure, metal rotation
Transfer rod 14 quickly rotates.Further, swivel head 142 is in round table-like, i.e., swivel head 142 is near the straight of one end of support column 141
Footpath is bigger away from the diameter of the other end of support column 141 than swivel head 142, so under the fire extinguishing material with high pressure, metal rotation
The speed that transfer rod 14 is rotated is faster.
In the present embodiment, the diameter of the mesh of screen pack 15 can so pass through less than the diameter of fourth hole 131
Screen pack 15 filters out the fire extinguishing material that particle is big or crystallizes, it is ensured that is sprayed from fourth hole 131 from fire extinguishing material, will not blocked up
Plug fourth hole 131.
Further, web plate is provided with the 3rd cavity 122 of nozzle metab 12, the wherein diameter of web plate is equal to the 3rd
The diameter of cavity 122, the diameter of the diameter less than metal rotation rod 14 of the mesh of web plate, and the 5th cavity 133 is away from the 4th chamber
One end of body 132 and the distance of web plate are equal or slightly larger than the length of metal rotation rod 14, with by web plate by metal rotation rod
14 are supported in the 5th cavity 133, and when the fire extinguishing material with high pressure sprays, fire extinguishing material can drive metal rotation rod 14
The rotation in the 5th cavity 133 so that the fire extinguishing material sprayed from fourth hole 131 is in atomization shape.
Further, the diameter of the mesh of web plate supports support column 141 less than the diameter of support column 141 with by web plate,
So as to metal rotation rod 14 is supported in the 5th cavity 133.
It should be understood that the extinguishing device of the present embodiment uses fluorinated ketone gas extinguishing agent as fire extinguishing material, and fluorinated ketone gas
The extinguishing effect of body extinguishing chemical is fabulous, but because the boiling point of fluorinated ketone gas extinguishing agent is 49 degree or so, therefore fluorinated ketone gas
Body extinguishing chemical is liquid under normal temperature state.Therefore when the extinguishing device of practical the present embodiment is put out a fire, the present embodiment goes out
Fluorinated ketone gas extinguishing agent can be changed into gasification by fiery device, specifically, fluorinated ketone gas extinguishing agent by extinguishing device, finally
Fluorinated ketone gas extinguishing agent (the i.e. fluorination of mist droplet shape in atomization shape is sprayed from the fourth hole 131 of Metallic Nozzle At The Ingot 13
Ketone gas extinguishing agent), and the fluorinated ketone gas extinguishing agent of mist droplet shape runs into air and gasifies rapidly, substantially increases fire extinguishing effect
Really.
To sum up, included by extinguishing device disclosed in this invention lower metal shell, screen pack, upper metal shell, spray
Mouth metab, Metallic Nozzle At The Ingot and metal rotation rod are constituted using metal material, with high-temperature resistant result so that extinguishing device exists
Its each part will not also melt under the condition of high temperature；In addition, being filtered to the fire extinguishing material for needing to spray by screen pack, make
Obtaining the larger fire extinguishing material of particle will not be ejected into Metallic Nozzle At The Ingot so that Metallic Nozzle At The Ingot will not be blocked；And by metal rotation
Rod rotates in Metallic Nozzle At The Ingot, fire extinguishing material is sprayed with being atomized shape, good extinguishing effect.
