A kind of fire extinguisher flow guiding disc of the present invention, structure is simple, cost of manufacture is low, easy and simple to handle, extinguisher valve is opened during use, high-pressure extinction agent is first injected in flow guiding disc after nozzle ejection, stop through flow guiding disc, shunt, extinguishing chemical spreads along the taper seat of flow guiding disc, shunts, and sprays to surrounding.After flow guiding disc water conservancy diversion, shunting, extinguishing chemical spray regime becomes large, and not needing people to adjust nozzle direction can expand the scope of strafing, and thus operating efficiency is high, is conducive to fire extinguishing rapidly in the short time.
Below in conjunction with accompanying drawing, a kind of fire extinguisher flow guiding disc of the present invention is described further.
Accompanying drawing explanation
Fig. 1 is the top view of a kind of fire extinguisher flow guiding disc of the present invention;
Fig. 2 is the A-A profile of Fig. 1;
Fig. 3 is the using state figure of a kind of fire extinguisher flow guiding disc of the present invention.
Detailed description of the invention
As shown in Figure 1 and Figure 2, a kind of fire extinguisher flow guiding disc of the present invention, comprise upper cover plate 1, upper cover plate 1 bottom surface is installed with inverted cone shape diversion division 2.Preferably, diversion division 2 is that a punching press is formed, and the structural stability formed like this is high, good toughness, stressed not fragile or distortion.And inverted cone surface is smooth, like this, or corner angle can not be had and affect the jeting effect of extinguishing chemical because of rough surface.The lower ring plate 3 parallel with upper cover plate 1 is provided with below diversion division 2, be provided with through hole in the middle part of lower ring plate 3, inverted cone summit just to through hole center and and there is interval between through hole, preferably, for ensureing good jeting effect, the spacing between inverted cone summit and the through hole center of circle is 15 ~ 20mm.Be less than this spacing, extinguishing chemical has just ejected just diversed portion 2 to be stopped and returns spray, and cannot be ejected at a distance, the shunting action of diversion division 2 is also very little.Be greater than this spacing, after extinguishing chemical sprays a segment distance, strength decays, and when causing arriving diversion division 2, the reaction force that diversion division 2 pairs of extinguishing chemicals are formed is large not, extinguishing chemical can drop on along the taper seat of diversion division 2 and closely locate, and can not be ejected at a distance by shunting.Lower ring plate 3 is fixedly connected with by dowel 4 with upper cover plate 1.Particularly, dowel 4 distributes along the circumferencial direction of inverted cone, and dowel 4 upper end is fixed on upper cover plate 1, and lower end is fixed on lower ring plate 3.For reducing dowel 4 to the impact of spraying, the cross section of dowel 4 is rectangle, that is, this dowel 4 is rectangle by the cross section after the plane parallel with lower ring plate 3 sections.
For ease of operation, reduce construction cost, upper cover plate 1 welds with diversion division 2, and dowel 4 two ends are welded with upper cover plate 1, lower ring plate 3 respectively.Certainly, the structure that upper cover plate 1 and diversion division 2 also can be formed in one, greatly strengthen the stability of flow guiding disc entirety like this, is not subject to high pressure and damages during use.
Equally, in order to increase the intensity of flow guiding disc entirety, upper cover plate 1, diversion division 2, lower ring plate 3, dowel 4 all adopt No. 10 steel or No. 20 steel to make.No. 10 steel plasticity, toughness are fine, and easy cold and hot working is shaped, and after normalizing or cold working, machinability is good.No. 20 steel belong to high-quality low-carbon (LC) carbon steel, and this steel toughness, plasticity and weldability are all good.The flow guiding disc load performance that these two kinds of steel are made is good, by not fragile during high-pressure extinction agent effect, is conducive to extending flow guiding disc service life.
For convenience, fire extinguisher is connected rapidly, lower ring plate 3 is equipped with fire extinguisher connecting hole along the circumferencial direction of through hole, for wearing bolt, like this, together with lower ring plate 3 can be bolted to connection with fire extinguisher, in emergency circumstances, such connected mode is convenient and swift, save time, and is convenient to fight a fire in time.
As shown in Figure 3, flow guiding disc of the present invention in use, be fixedly connected with fire extinguisher 5 by lower ring plate 3, open extinguisher valve 6, the high-pressure extinction agent in fire extinguisher 5 is just from nozzle ejection, and extinguishing chemical shunts backward surrounding rapid diffusion through diversion division 2 water conservancy diversion, because the effect of flow guiding disc, extinguishing chemical diffusion is fast, diffusion area is large, can be diffused rapidly to burning things which may cause a fire disaster region, reach the object of quick extinguishing.
Above-described embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
