Description
Technical field
This utility model belongs to fire extinguishing system, more particularly to a kind of dry powder, the dual-purpose fire extinguishing system of foam.
Background technology
Dry powder extinguisher in the market mostly is stored-pressure type or the single fire extinguisher with gas storage vial-type, and its shortcoming one is spray
Drive gas directly to contact with dry powder pharmaceutical without decompression when penetrating or storing, determine that its storage maximum pressure will not be too high, with
Exempt to work the mischief operator, also imply that its injecting time will not be oversize, especially with portable dry powder fire extinguisher as representative；Lack
Point two is that, with the carrying out of injection, storage pressure or gas storage pressure of the inside of a bottle can be gradually lowered, and the jet length of extinguishing medium can be by
Decrescence little, operator must move closer to flame and be put out a fire, and operator can be constituted dangerous；Shortcoming three is principle and knot
Structure determines which can only be as disposable fire services appliance in scene of fire, it is impossible to which scene carries out filling fire extinguishing medicine to which
Agent and repetition are put out a fire.And the extinguishing fluid of fixed froth installation is mixed by water and foam compound, determine its do not possess and
When put out a fire to save life and property the ability of appliance fire, it is necessary to can just be put out a fire in the case where power-off guarantees safety, and process afterwards
Also it is extremely onerous.
The content of the invention
It is an object of the invention to overcome above-mentioned technical deficiency, there is provided one kind is equipped with dry powder pharmaceutical and foam compound, root
According to live fire condition, dry powder, the dual-purpose fire extinguishing system of foam that corresponding medicament put out a fire is selected.
This utility model solves the technical scheme that adopted of technical problem：The dual-purpose fire extinguishing system of a kind of dry powder, foam, bag
Foam compound case and dry powder storehouse is included, foam compound case is connected with charging basket with level pressure leak valve；Foam compound case passes through four with pipeline
Logical, threeway two is connected with breathing component；It is characterized in that pipeline connection is used with reversing arrangement one in charging basket and dry powder storehouse；Commutation dress
Put one outlet pipeline to connect with the entrance of pneumatic diaphragm pump；Foam compound case and source of the gas pass through pipeline and decompressor leads to
Cross four-way, threeway one, commutate threshold switch, regulator one, reversal valve to connect with the left and right chamber of pneumatic diaphragm pump respectively, while using
Pipeline is connected with pneumatic diaphragm pump by regulator two；The outlet of pneumatic diaphragm pump passes through threeway three and reversing arrangement with pipeline
Two entrances are connected, and are connected with breathing component by check valve, threeway dual-purpose pipeline；Reversing arrangement dual-purpose pipeline is sprayed with dry powder
Gun apparatus two are connected, and are connected with foam maker with pipeline；Foam maker pipeline is connected with foam jet gun apparatus one.
The beneficial effects of the utility model are：The utility model can be in injection dry powder and spray foam by reversing arrangement
Between changed, you can put out a fire to save life and property valve, liquid fire without causing the pollution of dry-powder-type with foam；Also foam cannot can used
Fire attack, good extinguishing effect is carried out in time with dry powder when putting out a fire to save life and property.

Specific embodiment
Embodiment, referring to the drawings, the dual-purpose fire extinguishing system of a kind of dry powder, foam, including foam compound case 1 and dry powder storehouse 21,
Foam compound case 1 is connected with charging basket 3 with level pressure leak valve 2；Foam compound case 1 is with pipeline is by four-way 12, threeway 2 18 and exhales
Inhale component 9 to connect；It is characterized in that pipeline connection is used with reversing arrangement 1 in charging basket 3 and dry powder storehouse 21；Reversing arrangement 1
Outlet pipeline is connected with the entrance of pneumatic diaphragm pump 5；Foam compound case 1 and source of the gas 10 pass through pipeline and decompressor 11 leads to
Cross four-way 12, threeway 1, commutation threshold switch 14, regulator 1, the left and right chamber respectively with pneumatic diaphragm pump 5 of reversal valve 17
Connection, while connected with pneumatic diaphragm pump 5 by regulator 2 16 with pipeline；The outlet of pneumatic diaphragm pump 5 is passed through with pipeline
Threeway 3 22 is connected with 26 entrance of reversing arrangement, and is connected with breathing component 9 with pipeline by check valve 19, threeway 28；Change
Connected with dry powder injection gun apparatus 2 20 with pipeline to device 26, connected with foam maker 7 with pipeline；Foam maker 7 is used
Pipeline is connected with foam jet gun apparatus 1.
In system, A is the pump diaphragm direction of motion；B is fluid direction of motion；C is gas motion direction.
The operation principle of the utility model is：The source of the gas 10 of disposal, using positive-pressure type principle ejecting extinguishing medicament.Source of the gas 10
The driving gas for being accommodated is more than the driving gas of ordinary dry chemical fire extinguisher, and its injecting time also accordingly can extend, and drive gas
Jing after decompression, it is input into and drives gas membrane pump 5 to extract extinguishing medium out, charging basket 3 and foam can be always maintained at when siren is reported to the police
Chemical tank 1 is not stressed when system works, it is possible to carry out filling again for extinguishing medium in fire-extinguishing location, without the need for specially
Industry facility personnel, it is simple and convenient.
