Technical field
The utility model relates to a kind of for fire protection sector, firing-fighting medium is spurted the foam nozzle to presumptive area, adopts cross drainage plate to add inner convexed splash board structure, belong to fire-fighting fire extinguishing field.
Background technology
Current foam nozzle, spout, without dust prevention, is subject to dust, the gathering of greasy dirt, blocks shower nozzle duct, and usefulness is spurted in impact; Filter screen adopts built-in, cleaning, replacing inconvenience; Splash board is flat, spurts uneven, spurts apart from partially near.
Current foam nozzle is installed at the scene, is connected, when regulating deflection angle, often occurs leakage problems with pipeline; In the process of spurting, the reaction force that foam nozzle is spurted deflects often, and firing-fighting medium spurts less than presumptive area, causes fire extinguishing to lose efficacy.
Summary of the invention
Spurting uneven to solve usual foam shower nozzle, spurting apart from partially near; Spout is without dust prevention; Filter gauze cleaning, replacing inconvenience; The problem of Field adjustment angle easy to leak.The utility model provides a kind of foam nozzle, and adopt cross drainage plate to add inner convexed splash board structure, joint is connected with body by straight thread, by locking nut fit sealing, and the dust plug of spout configure band chain.
The utility model is achieved in that foam nozzle is made up of screw (1), splash board (2), dust plug (3), chain (4), drainage plate (5), shower nozzle (6), plug screw (7), O type circle (8), filter screen (9), body (10), locking nut (11), joint (12).Joint is connected the taper pipe thread of employing standard with engineering pipeline, joint and body adopt straight thread to connect, and locking nut is spun on the straight thread of joint, and body entrance is provided with counterbore, O type circle is housed, by locking nut at arbitrarily angled fit sealing in counterbore; Filter screen one inserts in body inlet opening, and one inserts in plug screw counterbore, fastening by plug screw; Body is provided with three shower nozzles; Stud with cross drainage plate in the middle part of the duct of top shower nozzle, inner convexed splash board is installed on the upside of shower nozzle; Middle shower nozzle adopts Jia Xieshang duct, straight hole road, is also provided with inner convexed splash board on the upside of shower nozzle; The water inlet of below shower nozzle is embedded with whirlpool device; Splash board and shower nozzle adopt insertion slot type to assemble, by 2 screw fastenings; In the spout of three shower nozzles, interference is embedded with dust plug, prevents dust, greasy dirt enters spout duct.When spurting, firing-fighting medium is entered by joint, filter screen, branches to three shower nozzles through body, sprays dust plug and spurts.Be suitable for protecting ship deck, hangar, vcehicular tunnel.
The beneficial effects of the utility model are: spout is provided with dust plug, avoid spout, duct is subject to dust, the gathering of greasy dirt, to block, guarantee to spurt usefulness; Design adopts plug screw, is convenient to filter gauze cleaning, replacing; Splash board design adopts inner convexed, and realizing wider scope of spurting simultaneously, what reach 16m spurts distance; Joint is connected with body by straight thread, by locking nut fit sealing, solves leakage problems when shower nozzle and pipeline adjusting angle.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is section of structure of the present utility model.
Fig. 2 is splash board profile of the present utility model.
Fig. 3 is front view of the present utility model.
Detailed description of the invention
Foam nozzle is made up of screw, splash board, dust plug, chain, drainage plate, shower nozzle, plug screw, O type circle, filter screen, body, locking nut, joint.Joint is connected the taper pipe thread of employing standard with engineering pipeline, joint and body adopt straight thread to connect, and locking nut is spun on the straight thread of joint, and body entrance is provided with counterbore, O type circle is housed, by locking nut at arbitrarily angled fit sealing in counterbore; Filter screen one inserts in body inlet opening, and one inserts in plug screw counterbore, fastening by plug screw, and plug screw and body adopt O type circle to seal, and is convenient to the cleaning of filter screen, changes operation; Body is provided with three shower nozzles, the angle of top shower nozzle and middle shower nozzle is 60 °, and the angle of middle shower nozzle and middle below shower nozzle is also 60 °.Stud with cross drainage plate in the middle part of the duct of top shower nozzle, inner convexed splash board is installed on the upside of shower nozzle; Middle shower nozzle adopts Jia Xieshang duct, straight hole road, is also provided with inner convexed splash board on the upside of shower nozzle; The water inlet of below shower nozzle is embedded with whirlpool device; Splash board adopts inner convexed, and adopt insertion slot type to assemble with shower nozzle, by 2 screw fastenings, splash board keeps concordant with the outer surface of shower nozzle, improves assembling intensity and spurts stability; In the spout of three shower nozzles, interference is embedded with dust plug, prevents dust, greasy dirt enters spout duct, affect it and spurt performance; Dust plug is fixed on below shower nozzle by screw by chain, in order to avoid dust plug impacts injury to the equipment of guard plot and personnel when spurting, the position that dust plug hangs from above is not interfered and spurted.When spurting, firing-fighting medium is entered by joint, filter screen, branches to three shower nozzles through body, sprays dust plug and spurts.The technical scheme in the invention for solving the technical problem is: through repeatedly spurting test, improve splash board, flatly inner convexed is improved to by traditional, top studs with cross drainage plate in the middle part of shower nozzle duct, makes waterflow stabilization, does not produce turbulent flow, keeps flinging kinetic energy, inner convexed splash board is realizing wider scope of spurting simultaneously, reach farther and spurt distance, when spurting the different medium of water, foam mixing liquid two kinds, reaching identical uniformity and spurting distance; Dust plug adopts mold pressing polytetrafluoroethylene (PTFE), is flush-mounted in shower nozzle spout, comes off under the pressure of≤0.2MPa.
1) material: shower nozzle, splash board, body, joint, filter screen, screw, chain adopt 10Cr18Ni12, plug screw, drainage plate, locking nut adopt copper alloy; O type circle adopts acrylonitrile-butadiene rubber; Dust plug is mold pressing polytetrafluoroethylene (PTFE).
2) rated operating pressure: 0.35MPa.
3) sealing load: 1.8MPa.
4) working pressure range: 0.3MPa-1.2MPa.
5) flow: 400L/min.
6) effectively distance is spurted: >=16m.
7) installing space is 6m, setting height(from bottom) 3.5m-8.0m.
8) medium is used: water, foam mixing liquid.
More than describe preferred embodiment of the present utility model in detail; Should be understood that the ordinary skill of this area just can make many modifications and variations according to this novel design without the need to creative work.Therefore, all technical staff in the art, according to this novel design, pass through logic analysis, reasoning or the available technical scheme of limited test on the basis of existing technology, all should in the protection domain that this is novel.
