Abstract
A differential pressure type multielement multi-function fire extinguishing device belongs to the field of fire extinguishing equipment. The device mainly comprises a water gun and an assistant agent conditioner which is internally filled with carbon tetrachloride extinguishing agent. After the extinguishing water enters into the water gun, the mixture of high-speed water flow and the extinguishing assistant agent is spurted into the fire field at the same time. The carbon tetrachloride occurs chemical reaction under high temperature so as to bring about the effect of fire fight in a manner of efficient, speedy, safe and nontoxic. Having the advantages of simple structure, reliable work and convenient usage, the utility model can be easily popularized and used on the prior fire extinguishing equipment and deeply welcomed by the fire fighters.
Description
The polynary multiaction extinguishing device of a kind of differential pressure type, it belongs to the fire-fighting equipment field.
Existing fire-fighting equipment is used water, carbon tetrachloride etc. always as extinguishing chemical.Flammable liquid concentration that water fire extinguishing has that cooling effect, secluding air play smothering action, the dilution water dissolubility is flammable, the percussion of waterpower and emulsification flammable liquid make its burning be difficult to multiple effects such as continuation, thereby be used as the most frequently used extinguishing chemical always, especially on various boats and ships, use very extensive.But water extinguishment requirement water column directly sprays to the burning things which may cause a fire disaster effect for best, otherwise just can't play the effect of fire extinguishing.Carbon tetrachloride (CCl
4) be the very strong liquid of a kind of volatility, it very easily gasifies and is the gas of not combustion-supporting proportion greater than air in the scene of a fire, plays the content that reduces oxygen in the air and puts out a fire.5～8% CCl is arranged in air
4During steam, burning will stop fully, and its fire-fighting efficiency is high.But CCl
4In fire extinguishing procedure, can produce the extremely phosgene (CO-C1 of poison
2), phosgene is typical ASPHYX, is the compound with the effect of damage lung tissue, reaching respective concentration can cause death.So now forbid CCl
4As main extinguishing chemical, existing quantity in stock is very big, how the chemical by-product CCl of enormous amount
4Again be used widely at fire-fighting domain, be the major issue that people are concerned about always.
The purpose of this utility model is: develop the polynary multiaction extinguishing device of a kind of differential pressure type.This device should be main extinguishing chemical with water, and carbon tetrachloride is secondary extinguishing chemical, overcomes independent water or carbon tetrachloride all shortcomings as main extinguishing chemical, becomes the extinguishing device of high effect nontoxic.This device also should be simple in structure, reliable operation, and cost is low, and is easy to use, is convenient to apply on existing fire-fighting equipment.
Technical solution of the present utility model is: the polynary multiaction extinguishing device of a kind of differential pressure type, and it mainly comprises a water band, snap joint, hydraulic giant body and nozzle, snap joint links together water band and hydraulic giant body.Special character of the present utility model is: it also comprises a secondary agent container, ball valve, hand-tight joint and adapter, and one of them adapter is located on the maximum gauge section of hydraulic giant body, and another adapter is located on the nozzle.The hydraulic giant body is connected with an end of secondary agent container with ball valve through adapter, hand-tight joint.Nozzle is connected with the other end of secondary agent container with ball valve through adapter, hand-tight joint.
Above-mentioned nozzle length is 50～150 millimeters, and nozzle is threaded with the hydraulic giant body and function and is integral.
The secondary agent of adorning in the above-mentioned secondary agent container is a carbon tetrachloride.
The guiding theory of above-mentioned technical solution is: the fire extinguishing host that the polynary multiaction extinguishing device of this differential pressure type adopts---water is pressurized laggardly goes in the hydraulic giant, shrink gradually in the cross section of hydraulic giant inwall, water obtains through shrink nozzle quickening, in the exit of jet pipe, the flow velocity of water can approach velocity of sound.Exert sharp equation principle by one hundred, the water flow velocity of hydraulic giant porch will be lower than the water flow velocity at nozzle place, and therefore, the hydraulic pressure that the hydraulic pressure of hydraulic giant porch will be higher than nozzle exit by force is strong.Employing is drawn adapter at hydraulic giant enlarged diameter section (porch) and nozzle segment (exit) and is linked to each other with secondary agent container, utilizes the differential water pressures at place, gateway in the hydraulic giant, and the secondary agent of fire extinguishing (carbon tetrachloride) in the secondary agent container of injection sprays to the scene of a fire fast.The polynary extinguishing chemical that water and carbon tetrachloride are formed absorbs heat under the high temperature in the scene of a fire, gasification and chemical reaction, produces efficient and nontoxic fire extinguishing effect.
Effect of the present utility model is: the polynary multiaction extinguishing device of this differential pressure type, mainly form by water band, hydraulic giant and secondary agent container.Because the carbon tetrachloride of hydraulic giant in the secondary agent container of injection under the effect of press water, the poisonous phosgene that carbon tetrachloride is produced changes the CO that helps putting out a fire fully under the high temeperature chemistry effect
2, strengthened the fire extinguishing effect.Evidence: for the similar scene of a fire, the polynary multiaction extinguishing device of differential pressure type only used for 8～9 seconds, and fire is put out fully, detected no poisonous phosgene and existed; During simple water, sued and laboured one minute, the intensity of a fire does not have obviously and weakens.As seen, this extinguishing device is simple in structure, reliable operation, and cost is low, and is easy to use, high effect nontoxic.When suing and labouring, need not directly aim at the scene of a fire,, just can play good fire extinguishing effect as long as aim at space, the scene of a fire; Very be convenient on existing fire-fighting equipment, promote the use of, be subjected to numerous fire fighters' welcome deeply.
Description of drawings:
Accompanying drawing 1 is the structure chart of the polynary multiaction extinguishing device of a kind of differential pressure type.
Be embodiment of the present utility model below, description and accompanying drawing by to this embodiment provide details of the present utility model.
Fig. 1 is the structure chart of the polynary multiaction extinguishing device of a kind of differential pressure type.Among the figure, water band (1) links together through snap joint (2) and hydraulic giant body (3), and length is that 100 millimeters nozzle (4) leans on screw threads for fastening on hydraulic giant body (3), and the inner chamber of hydraulic giant body (3) becomes the cross section of shrinking gradually, constitutes a shrink nozzle.The enlarged diameter section of hydraulic giant body (3) is provided with adapter (6), jet pipe (4) is provided with adapter (7), be respectively equipped with ball valve (10) (11) on the secondary agent container (5), hand-tight joint (8) links together with ball valve (10) taking over (6), and hand-tight joint (9) links together with ball valve (11) taking over (7).Secondary agent container (5) lining is filled fire extinguishing secondary agent carbon tetrachloride (12) in advance, also can adopt 1211 extinguishing chemicals to replace carbon tetrachloride.
