Description
Technical field
The utility model belongs to fire-fighting equipment technical field, and in particular to a kind of portable fire extinguishing of D classes with loudspeaker nozzle
Device.
Background technology
Chinese patent notification number is that CN202844419 patent discloses a kind of D type fire extinguisher, including cylinder body of fire extinguisher,
Cylinder is provided with pressure and valve body, and valve body is connected by jet pipe with decompression nozzle, and decompression nozzle is the decompression of adjustable pressure
Nozzle；Decompression nozzle includes sprayer body, and sprayer body one end is to be provided with into agent mouth, the other end and open porose nozzle cap, sprayer body
Flour extraction end is provided with rotatable regulation and covered, and regulation cover front end is the regulation lid provided with adjustment hole, and regulation lid is located at nozzle cap front end；
Sprayer body circumference is provided with bulge loop, and the circumferential inner wall for adjusting cover is provided with the scrobicular ring being adapted with bulge loop, the bulge loop position of sprayer body
In in the scrobicular ring of regulation cover.
Fire is categorized as A, B, C, D, E, F, and be most difficult to put out works as number D class light-weight metal fire, due to light-weight metal
Class material has very strong oxidisability, meets water and just produces combustion explosion, also more specialized to the technical need of fire extinguisher.
When putting out special light-weight metal fire, stamped out a fire, can be prevented when using the D class specialty fire extinguishers with decompression nozzle design
It is excessive only to there is extinguishing chemical ejection pressure, combustible substance is beaten and flown to above the original material without burning, causes the fast of fire
Speed expands.However, fire-fighting efficiency now is relatively low, and substance combustion can all discharge substantial amounts of light and heat, particularly D classes material
Fire when personnel are put out a fire more by force due to heat radiation often dare not be close, and need using stamping out a fire more at a distance, to prevent
Only personnel burn.
Summarize existing D classes specialty fire extinguisher and shortcoming be present：When using without decompression nozzle, fire extinguishing dynamics deficiency, fire extinguishing
Personnel need to closely put out a fire, and cause potential safety hazard；When using non-band decompression jet pipe, combustible substance beats to fly to did not burnt originally
Material above, cause the rapid expansion of fire.Therefore need design one kind to be both avoided that and efficiently complete fire extinguishing, and can guarantee disappears
The personal safety of anti-personnel.
Utility model content
The utility model is mainly to solve the technical problem present in prior art, a kind of with loudspeaker nozzle so as to provide
