Description
Technical field
The present invention relates to fire extinguisher fields, more particularly to a kind of superfine powder fire extinguisher.
Background technique
Suspended type ultrafine dry powder fire extinguisher, be two poles, bracket etc. by hang or wall in the form of by ultra-fine dry powder
Fire extinguisher is placed in above protected object.In existing hanged extinguishing equipment, there are two types of automatic Starting mode is usual, one is
Startup temperature is determined using temperature sensing glass ball, when temperature sensing glass ball, which perceives scene, reaches this limiting temperature, starts extinguishing device；Separately
One is electromagnetic start mode is used, the switch in dry powder channel is controlled by electromagnetic temperature-sensitivautomatic element.
Suspended type ultrafine dry powder fire fighting with fire extinguisher principle：Since the extinguishing chemical partial size filled is small, good fluidity has good anti-
Re-ignition, dispersivity and electrical insulating property, extinguishing mechanism are to pass through chemistry, the dual fire extinguish of physics based on inhibition
It stamps out the flames：The isolation of protected object and air is physically realized, blocks the required oxygen that burns again, physically
Prevent re-ignition；Chemical aspect, the ultra-fine dry powder extinguishing agent powder that automatic fire extinguisher releases by with comburant flame contact,
Generate chemical reaction and capture burning free radical and heat rapidly, flame is put out to cut off pyric chain realization, extinguishing chemical with
A large amount of glass that flame reaction generates are attached to protected object surface from the suction of shape substance and form one layer of separation layer；Therefore it both can apply to
Relative closure space total flooding fire extinguishing, it can also be used to open place localised protection fire extinguishing.The extinguishing device is transported according to model difference
For archive office, field storehouse before and after automobile, kitchen, office space, construction, storehouse laboratory, electronic industry, it is dining room, small
The places such as the type shop front, electronics computer room.
Existing most of suspended type ultrafine dry powder automatic fire extinguishers only have an extinguishing chemical ejiction opening, and ejiction opening direction
Be it is fixed, when being put out a fire by extinguishing chemical high pressure spray, encounter lower section object after spread around, thus realize go out
Fire；But this kind of mode, since the direction of nozzle is fixed, so fire extinguishing can only be oriented, overlay area is smaller, is unable to satisfy
Large range of extinguishment requirement.

The threaded connection of two valve bodies 400 keeps it easy to disassemble, convenient to carry out integral replacing after temperature-sensing element damage, facilitates returning for valve body
It receives and secondary maintenance produces.
The operation principle of the present invention is that：
Superfine powder fire extinguisher suspension is mounted on suitable location, it is necessary first to explanation, the heat-sensitive line 450
With the triggering temperature close of first temperature-sensing element 330, when fire behavior occurs, ambient temperature reaches first temperature-sensitive
The triggering temperature of element 330, first temperature-sensing element 330 ruptures, while the heat-sensitive line 450 transmits rapidly fire signal
To second temperature-sensing element 440, second temperature-sensing element 440 ruptures；When first temperature-sensing element 330 rupture, institute
The ejiction opening that the first sealing-plug 320 is detached from first valve body 300 is stated, the extinguishing chemical in first tank body 100 is internal high
It calms the anger under the action of body, sprays rapidly, expand the range of extinguishing chemical under the action of the circular hole 340 and the diffuser plate 350
Greatly, while what is carried out has second temperature-sensing element 440 to rupture, and second sealing-plug 430 is detached from second valve body 400
Ejiction opening, the extinguishing chemical in second tank body 200 spray rapidly, under the action of internal high-pressure gas in the seal box
410 and the gas nozzle 500 under the action of make extinguishing chemical along the side wall of second tank body 200 tangential direction spray, it is described
First tank body 100 and second tank body 200 realize rotation under the reaction force of high-pressure extinction agent, realize to spray in rotation and go out
The movement of fiery agent improves fire-fighting efficiency to obviously expand fire extinguishing overlay area；Wherein, when the spray downwards of the first valve body 300
Out when high-pressure extinction agent, a upward reaction force can be provided to first tank body 100 and second tank body 200, very
First tank body 100 and second tank body, 200 entirety can be extremely set to move up certain position, at this time the hanging plate
630 bottom supports second ball 670, prevents the rotation for influencing first tank body 100 and second tank body 200；
And it is opposite, when reaction force is less than first tank body 100 and 200 self gravity of the second tank body, the extension at this time
The roof of plate 630 supports first ball 660, same to can avoid influencing first tank body 100 and second tank body 200
Rotation, therefore, under overall co-ordination can smoothly realize and spray the movement of extinguishing chemical in rotation.
The present invention is described with reference to the preferred embodiments, and those skilled in the art know, of the invention not departing from
In the case where spirit and scope, various changes or equivalence replacement can be carried out to these features and embodiment.The present invention is not by this
The limitation of specific embodiment disclosed in place, other embodiments fallen into claims hereof belong to protection of the present invention
Range.
