Abstract
The utility model relates to a high-pressure straight stream fire water branch comprising a branch body, wherein a ball valve which is connected with a switch knob at the outer side of the branch body is arranged in the branch body, the rear end cover of the branch body is connected with a rear connecting piece which is provided with a quick joint used for connecting a high-pressure pipe quickly, the front end cover of the branch body is connected with a front connecting rod which is equipped with a nozzle device, and a handle is further arranged on the branch body. The high-pressure straight stream fire water branch provided by the utility model is simple in structure, small in size and light in weight and is conveniently stored and carried. By pressurizing water into the branch through a high-pressure pump, generating drops by striking, smashing and atomizing with an atomization regulator, and forming straight stream thick fog and a tapered high-pressure water-curtain protection surface, the jet distance can reach 25 meters and the fire suppression efficiency is good.
Description
Technical field
The utility model relates to the fire prevention field, especially relates to a kind of HVDC fire-fighting lance.
Background technology
At present, the hydraulic giant that is used for fire-fighting fire extinguishing can only spray single water column shape or swallow-tail form current, this traditional fire-fighting mode is not only wasted a large amount of water sources, its poor effect of putting out a fire because the particle water yardstick that ejects is big, is easy to drop to ground under the gravity effect and becomes invalid trickling water, water use efficiency reduces, a large amount of loss water also may cause the water stain pollution of secondary, and jet length is short, cause the destruction to protection object simultaneously easily.
Because thin water smoke fogdrop diameter is very little, the water of same relatively volume, its surface area increases severely, thereby has strengthened the usefulness of heat exchange, has played extraordinary cooling-down effect; Be vaporized rapidly after thin water smoke absorbs heat, make volume sharply expand, reach more than 1700 times usually, thereby reduced airborne oxygen concentration, suppressed the speed of aflame oxidation reaction, played the effect that suffocates.This shows the extinguishing mechanism of thin water smoke: the one, cooling usefulness absorbs heat; The 2nd, smothering action, the blocking oxide reaction, in addition, thin water smoke has the usefulness of very superior blocking-up radiant heat transfer, can block strong heat radiation effectively.As seen, adopting fine mist fire-fighting is an extraordinary fire extinguishing skill technology that is worthy to be popularized.
Therefore, a kind of simple in structure, the appearance of HVDC fire-fighting lance that can produce thin water smoke is necessary.
The utility model content
The utility model is to provide a kind of simple in structure for solving the problems of the technologies described above, and can produce the HVDC fire-fighting lance of thin water smoke.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of HVDC fire-fighting lance comprises the rifle body, is provided with ball valve in described rifle body, and described ball valve links to each other with the switch knob that is arranged at the external side of described rifle, to control the switch of described rifle body;

Drive end bearing bracket at described rifle body is connected with front rod, is provided with ejecting device at described front rod;
On described rifle body, also be provided with handle.
As optimized technical scheme, described ejecting device and described front rod are spirally connected fixing, described ejecting device comprises the shower nozzle inner core, the shower nozzle overcoat, water knockout drum and atomizing adjuster, described water knockout drum is sheathed on the afterbody of described atomizing adjuster, and is provided with described shower nozzle inner core inside, and described shower nozzle overcoat is set in the described shower nozzle inner core outside.
As optimized technical scheme, the shower nozzle of described atomizing adjuster is arranged at the fan nozzle place of described shower nozzle overcoat.
As optimized technical scheme, the shower nozzle of described atomizing adjuster is conical.
As optimized technical scheme, described shower nozzle puts outward and is provided with through hole.
As optimized technical scheme, be provided with the above sealing ring of one deck between described shower nozzle overcoat and the shower nozzle inner core.
As optimized technical scheme, in described quick street corner, jump ring is arranged fixedly, fix flexible parts at described jump ring, on described elastomeric element, also be provided with check valve, described check valve is placed in the afterbody of described snap joint, in the impact of high-pressure water pipe, described check valve inwardly compresses, and makes water pass described snap joint and enters the rifle body.
As optimized technical scheme, described elastomeric element is spring.
The beneficial effect that the utlity model has is: simple in structure; volume is little, in light weight, storage and carrying; pressurization enters hydraulic giant through high-pressure pump with water; again through with the atomizing adjuster bump, break up, the atomizing; produce drops; the thick water smoke of jet gun interruption-forming direct current and taper high pressure cascade protective surface, jet length reaches 25 meters, good extinguishing effect.
