Description
Technical field
The utility model belongs to the end flusher of fire-fighting system, is specifically related to AFFF fire extinguishing system end spray application, particularly relates to a kind of foam umbrella shape shower nozzle.
Background technology
The deck of large ship is parked numerous aircraft and numerous auxiliary equipment thereof, security protection is needed to aircraft and equipment, comprise AFFF fire extinguishing system in multiple safeguard procedures.Shower nozzle is the significant components that AFFF fire extinguishing system end sprays; the spray effect of shower nozzle directly affects fire extinguishing quality and the efficiency of AFFF fire extinguishing system; the success or failure of the flow of shower nozzle and the fire extinguishing of radius of protection direct relation are the important parameters of foam nozzle.Have multiple shower nozzle on the market at present, mist particle diameter is little, and radius of protection is also little, and flow is little, needs elevated pressures during some shower nozzle atomized sprays.Therefore need to improve existing shower nozzle.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of foam umbrella shape shower nozzle, and spray pattern is inverted umbrella shape, rapidly AFFF can be sprayed onto protection zone.
For realizing above-mentioned technical purpose, the utility model adopts following technical scheme to be achieved.
A kind of foam umbrella shape shower nozzle, comprises baffle plate, sprayer body, guide rod, baffle, locking nut, joint; Described baffle plate is connected with described guide rod screw top; Described baffle plate bottom surface is the first taper surface, and described sprayer body top is provided with the second taper surface, and described first taper surface coordinates with described second taper surface; Baffle and joint is provided with successively from top to bottom in described sprayer body; Described guide rod is jag through the part of baffle, and described jag is threaded locking nut.
As preferably, described baffle is provided with pilot hole, and described guide rod is arranged in pilot hole.
As preferably, described joint is provided with taper thread, is connected by the pipe collar of taper thread with AFFF fire extinguishing system end pipe network.
As preferably, described baffle plate, sprayer body, guide rod, baffle, locking nut, joint all adopt stainless steel to make.
The beneficial effects of the utility model are: the utility model is cooperatively interacted by the first taper surface of described baffle plate and the second taper surface of described sprayer body, injection water film-forming foam and water spray pattern is made to be inverted umbrella shape, rapidly AFFF can be sprayed onto protection zone, when shower nozzle does not work, first taper surface and described second taper surface are combined closely, and can prevent the water outside shower nozzle and foul from flowing into; Can carry out large discharge sprinkling, protection zone is large, and stretching out height by controllable register can be sprayed to protection zone by AFFF or water rapidly.
Accompanying drawing explanation
Fig. 1 is the partial cutaway schematic of the utility model embodiment.
In figure: 1. baffle plate; 2. sprayer body; 3. guide rod; 4. baffle; 5. locking nut; 6. joint; 7. the first taper surface; 8. the second taper surface.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A kind of foam umbrella shape shower nozzle described in the utility model embodiment; as the end spray assembly of AFFF fire extinguishing system; can vertical ground or deck level upwards spray; can according to the quantity of the flow of shower nozzle and spray radius determination foam umbrella shape shower nozzle and layout; reach protection zone safety or put out the object of fire of protected field; reduce fire damage, also can be used for the fire-fighting fire extinguishing of large-scale oil sump, also can be used for fire fighting test.
Please refer to Fig. 1, described foam umbrella shape shower nozzle comprises baffle plate 1, sprayer body 2, guide rod 3, baffle 4, locking nut 5, joint 6; Described baffle plate 1 is connected with described guide rod 3 screw top; Sprayer body 2 is positioned at the below of described baffle plate 1, and coordinates with the form of the conical surface with baffle plate 1; Baffle 4 and joint 6 is provided with from top to bottom successively in sprayer body 2; Described guide rod 3 is jag through the part of described baffle 4, jag is connected with locking nut 5; Described locking nut 5 is positioned at below described baffle 4, has the effect of locking and regulating fender 1 lifting height.In fire extinguishing procedure, shower nozzle damages, and can realize reusing, and the baffle plate 1 of described shower nozzle, sprayer body 2, guide rod 3, baffle 4, locking nut 5, joint 6 all adopt stainless steel to make.
Described baffle plate 1 has the first taper surface 7, and described sprayer body 2 has the second taper surface 8, and described first taper surface 7 coordinates with described second taper surface 8, forms the cooperation of conical surface form.When baffle plate 1 moves up, the first taper surface 7 moves up, and makes to form gap between the first taper surface 7 and the second taper surface 8, and AFFF is sprayed away with umbrella form by gap.Described sprayer body 2 is not only the installation main body of baffle 4 and joint 6, and has equally distributed effect to AFFF mixed liquor, is provided with baffle 4 in sprayer body 2, the AFFF mixed liquor and water that enter shower nozzle can be uniformly distributed.
Be provided with pilot hole in baffle 4, described guide rod 3 is arranged in pilot hole, and described guide rod 3 can move up and down in baffle 4 pilot hole, completes baffle plate 1 and moves up and down.Sprayer body 2 has square face, baffle 4 convenient for assembly.Described joint 6 can compress baffle 4, stops baffle 4 to move axially.Described joint 6 is provided with taper thread, is connected by the pipe collar of taper thread with AFFF fire extinguishing system end pipe network.
During use, foam umbrella shape shower nozzle is placed in the preformed hole of ship deck, ensure that the upper plane of shower nozzle is concordant with above deck, shower nozzle is connected with the end pipeline of AFFF, when on deck during breaking out of fire, start AFFF fire extinguishing system, foam umbrella shape shower nozzle with the pressure of MJPZ mixed liquor for tripping force, under the pressure effect of MJPZ mixed liquor, open rapidly baffle plate 1, baffle plate 1 is made to exceed above installation, AFFF will be gone out by foam umbrella shape sprinkler, machinery equipment in protection spray radius, foam umbrella shape shower nozzle is mainly used in injection water film-forming foam and water, rated operating pressure is 0.4MPa, spray radius 4.6m, metered flow is 3.4L/S, spraying altitude can reach 3m, spray pattern is inverted umbrella shape, rapidly AFFF can be sprayed onto protection zone.
Obviously, those skilled in the art can carry out various change and modification to the utility model and not depart from spirit and scope of the present utility model.Like this, if these amendments of the present utility model and modification belong within the scope of the utility model claim and equivalent technologies thereof, then the utility model is also intended to comprise these change and modification.
