Abstract
The utility model relates to a dry powder fire-extinguishing tube which comprises a tube body, a powder chamber, dry powder, a piston, etc. The dry powder fire-extinguishing tube is characterized in that a spray pipe plate is arranged between the front part of the powder chamber and the tube body, a plurality of spray pipe holes are arranged on the spray pipe plate, the shape of the spray pipe holes is the shape of a laval spray pipe or other similar spray pipes, and the powder is ignited by the electric ignition mode. Due to the adoption of the spray pipe technique, the gas spray speed is improved, the spray range is more than 10 meters, the fire extinguishing area is large, and the shoot is accurate. The spray pipe plate is easy to replace, so the cost is low.
Description
The utility model relates to small-sized emission-type dry powder extinguisher.
Existing small-sized emission-type dry powder extinguisher comprises cylindrical shell, powder chamber, dry powder, boosting cover and end cap etc.The gas and the boosting cover that produce after utilizing gunpowder to ignite are dished out dry powder.The fuel gas injection speed that this powder chamber produces is lower, thereby the dry powder projection is not far, the fire extinguishing weak effect.
The purpose of this utility model is to improve the jet velocity of powder chamber combustion gas, thereby makes the farther of dry powder impelling, enlarges fire-fighting area.
Solution of the present utility model is: the place ahead at existing powder chamber is provided with nozzle plate, has at least one jet pipe hole on the nozzle plate.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the profilograph of first kind of embodiment of dry powder fire extinguisher.
Fig. 2 is the profilograph of another kind of embodiment.
Fig. 3 is the front view of nozzle plate.
Fig. 4 is the side view of Fig. 3.
Referring to Fig. 1, be filled with dry powder 3 in the cylindrical shell 1 of emission-type dry powder fire extinguisher, nozzle seals with end cap 5.The fire extinguisher afterbody has powder chamber 2.Between powder chamber the place ahead and cylindrical shell, be provided with nozzle plate 6, have some jet pipes hole 7 on it.The shape of nozzle plate is shown in Fig. 3,4, and wherein De Laval noz(zle) is preferably adopted in jet pipe hole 7, and conical nozzle or other similar jet pipe are to produce supersonic airstream.Generally there is changeover portion in the throat of jet pipe.
The leaded hole 21 of powder chamber 2 afterbodys can adopt common fuse or electric ignition device to ignite.
The fire extinguisher cylindrical shell is generally cylindrical, and in order to improve spray area, the front portion of this cylindrical shell 1 can have 3-8 ° tapering.
During use, the general electricity consumption sparking mode gunpowder that ignites, the high velocity air that ejects from jet pipe promotes piston 4 forward, and dry powder is dished out.For the piston in the tube can be used repeatedly, at cylinder inboard wall limit flange 12 can be set, block piston and make its unlikely flying out, still can continue after the powder charge again to use.
For ease of hand-held, the cylindrical shell afterbody has the external screw thread 10 with the handle socket, can with the socket of rifle shape handle, become the pistol type moulding.
This dry powder fire extinguisher has improved fuel gas injection speed greatly owing to adopted the jet pipe technology, and the dry powder range reaches more than 10 meters, and the dry powder surplus ratio is low, and fire-fighting area is big, drives the cross, and the fire extinguishing effect obviously improves.The main body of fire extinguisher and nozzle plate, piston etc. all can use repeatedly, thereby cost is low, is easy to apply.
