Abstract
The utility model discloses a D-type fire extinguisher. The D-type fire extinguisher comprises a fire extinguisher barrel body, wherein a pressure bar and a valve body are arranged on the barrel body; the valve body is connected with a pressure reducing spray nozzle by a spray tube; the pressure reducing spray nozzle is a pressure reducing spray nozzle with adjustable pressure; the pressure reducing spray nozzle comprises a spray head body, wherein an agent inlet is arranged at one end of the spray head body; a spray head cover with a hole is arranged at the other end of the agent inlet; a water outlet end of the spray head body is provided with a rotatable adjusting cover; an adjusting cover with an adjusting hole is arranged at the front end of the adjusting cover; the adjusting cover is arranged at the front end of the spray head cover; a convex ring is arranged at the periphery of the adjusting cover; a concave ring which is adaptive to the convex ring is arranged on the inner wall of the periphery of the adjusting cover; and the convex ring of the spray head body is arranged in the concave ring of the adjusting cover. For the D-type fire extinguisher provided by the utility model, the required pressure status of the reducing spray nozzle can be rapidly adjusted according to the requirements, the agent outlet pressure of the pressure reducing spray nozzle can be determined according to the practical conditions during the fire extinguishing process for adapting to fire disasters of different conditions, so that the fire extinguishing efficiency of the D-type fire extinguisher is greatly improved, and the fire extinguishing effect is remarkable.
Description
Technical field
The utility model belongs to the fire-fighting equipment technical field, is specifically related to a kind of fire extinguisher.
Background technology
Fire is categorized as A, B, C, D, E, F, and the most difficult working as of putting out counted (D class) light-weight metal fire, because light-weight metal class material has very strong oxidisability, meets water and just produces combustion explosion, and is also specialized to the technical need of fire extinguisher.When putting out special light-weight metal fire, should adopt (D class) professional fire extinguisher of band decompression Nozzle Design to stamp out a fire, it is excessive to prevent extinguishing chemical ejection pressure, combustible substance is beaten fly to above the material that does not have burning originally, causes the rapid expansion of fire.The jet pipe of existing D class fire extinguisher is realized decompression by being connected with the decompression nozzle, because it can not regulate the extinguishing chemical expulsion pressure, and the spray volume of extinguishing chemical big or small constant, for the ignition point that uses different distance, it is constant that it goes out agent pressure, the impact effect of putting out a fire.
The utility model content
For solving the problems of the technologies described above, the utility model aims to provide a kind of D class fire extinguisher, and the decompression nozzle of its adjustable pressure to be applicable to the fire ignition point of heterogeneity and distance, uses flexibly, and fire-fighting efficiency is high.
The technical scheme that the technical problem that the utility model solves adopts is:
A kind of D class fire extinguisher comprises cylinder body of fire extinguisher, and cylindrical shell is provided with pressure and valve body, and valve body is connected with the decompression nozzle by jet pipe, and the nozzle that it is characterized in that reducing pressure is the decompression nozzle of adjustable pressure.
During implementation, the decompression nozzle comprises sprayer body, and sprayer body one end is for advancing the agent mouth, the other end is provided with the nozzle cap that has the hole, the water side of sprayer body is provided with rotatable adjusting cover, and regulating the cover front end is the adjustable cap that is provided with adjustment hole, and adjustable cap is positioned at the nozzle cap front end.Regulate cover by regulating rotation, the hole of nozzle cap and the adjustment hole of adjustable cap go out the lipostomous size of extinguishing chemical, and the size of the spray volume of control extinguishing chemical is to regulate the extinguishing chemical expulsion pressure.
During implementation, the sprayer body circumference is provided with bulge loop, and the circumferential inner wall of regulating cover is provided with the scrobicular ring suitable with bulge loop, and the bulge loop of sprayer body is positioned at the scrobicular ring of regulating cover.By regulating cover and the concavo-convex cooperation of sprayer body, realize sprayer body and regulate being rotatably connected between the cover.When concrete the use, the detent mechanism of various states can be set.
During implementation, the decompression nozzle is connected with long metal pipe, and long metal pipe is connected with jet pipe.Increase long metal pipe and add long handle as what the fire fighter handed, consider the ignition temperature of metal fire, burn to prevent the user of service.
The beneficial effects of the utility model are: the utility model is the pressure state of the required decompression nozzle of quick adjustment as required, can go out agent pressure according to what actual conditions were determined the decompression nozzle during fire extinguishing, to be applicable to the fire of different situations, improve widely the fire-fighting efficiency of D class fire extinguisher, its successful.
Description of drawings
Below in conjunction with drawings and Examples utility model is further specified.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the reduce pressure structural representation of nozzle of the utility model embodiment.
Among the figure: 1, cylindrical shell 2, Pressure gauge 3, press 4, valve body 5, jet pipe 6, decompression nozzle 7, long metal pipe 61, sprayer body 62, advance agent mouth 63, hole 64, nozzle cap 65, regulate cover 66, adjustment hole 67, adjustable cap 68, bulge loop 69, scrobicular ring.
The specific embodiment
