Description
Technical field
The present invention is novel to be related to a kind of for fire protection sector, fire-fighting current is decomposed into the fine mist spray head of the droplet ejection of 35um--80um, uses multiple flow passages design, double medium atomization structure, belong to fire-fighting fire extinguishing, control fire field.
Background technology
Waterfog head in existing national standards GB5135.5-2003, operating pressure is at 0.35MPa-0.80MPa, and Pcnten-1 yne-4 is between 0.4mm-0.8mm, and flow is bigger than normal, reaches 80L/min-120L/min, exports normally opened, is not provided with dust cover.
Current waterfog head uses single pressure medium atomization, and the power of required medium is higher, droplet leave nozzle after kinetic energy decay rapidly, scene of a fire thermal current, fire plumage interference under easily fly away deviation, effective jet length is short.Inadequate shielding boiler room, hydraulic oil unit, lubricating oil station, archives historical relic, high voltage variable controller switching equipment, telecommunications room place.
Summary of the invention
In order to solve, conventional waterfog head droplet is thick, flow big, easily flies away deviation, the problem that effective jet length is short.This utility model provides a kind of fine mist spray head, use multiple flow passages design, double medium atomization structure, use multiply preshoot air-flow to be smashed by current, mix, hold under the arm and wrap up in, make droplet possess bigger kinetic energy, thermal current, fire plumage can be penetrated, arrive flame root and realize heat absorption, vaporization, quick extinguishing；Outlet configuration dust cover.
This utility model is achieved in that fine mist spray head is made up of dust cover (1), nozzle (2), nut (3), intermediate (4), sprayer body (5), pulverizer plate (6), filter screen (7), packing ring (8), clamping screw (9), sealing ring (10).Filter screen plug is in sprayer body water inlet, air inlet screw, by packing ring compression, clamping screw fastening；Intermediate is tightened on the left of sprayer body, uses sealing ring to seal；Pulverizer plate interference is flush-mounted in intermediate entrance side, nozzle bore and intermediate protruding shaft matched in clearance, nut spell tight；Nozzle cylindrical is cased with dust cover.When spurting, compressed air enters through filter screen from sprayer body air inlet screw, arrives scrobicular ring road through sprayer body gas transmission duct, after entering nozzle scrobicular ring road by the several uniform venthole of intermediate, then flows into several uniform straight hole road and is sprayed by inclined channel；Fire water supply flows into through filter screen through sprayer body water inlet screw, enter intermediate center flow channels after spinning up to pulverizer plate shunting, shrink duct, circular cone enlarging, to nozzle, being smashed to hold under the arm by nozzle chamber multiply preshoot air-flow and wrap up in, the dust cover that blows off is that air water two-phase is spurted.Be suitable to protect boiler room, hydraulic oil unit, lubricating oil station, archives historical relic, high voltage variable controller switching equipment, telecommunications room place.
The beneficial effects of the utility model are: use multiple flow passages design, double medium atomization, achieve water uniformly to mix with air, due to the dilatancy of compressed gas, bigger than the droplet kinetic energy of single-phase flow fine mist spray head, water consumption is few, possesses and bigger penetrates thermal current, the ability of fire plumage.
Accompanying drawing explanation
Further illustrate the present invention is novel with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is section of structure of the present utility model.
Fig. 2 is outline drawing of the present utility model.
Fig. 3 is nozzle section figure of the present utility model.
Detailed description of the invention
Filter screen plug is in sprayer body water inlet, air inlet screw, by packing ring compression, clamping screw fastening；Intermediate is tightened on the left of sprayer body, uses sealing ring to seal；Pulverizer plate interference is flush-mounted in intermediate entrance side, nozzle bore and intermediate protruding shaft matched in clearance, nut spell tight, and employing sealing ring is axial, radial seal；Nozzle cylindrical matrix annular groove inner sleeve has dust cover.When spurting, compressed air enters through filter screen from sprayer body air inlet screw, arrives scrobicular ring road through sprayer body gas transmission duct, enters after nozzle scrobicular ring road all presses by the several uniform venthole of intermediate, then flows into several uniform straight hole road and sprayed by inclined channel；Fire water supply flows into through filter screen through sprayer body water inlet screw, enter intermediate center flow channels after spinning up to pulverizer plate shunting, shrink duct, circular cone enlarging, to nozzle, being smashed by nozzle chamber multiply preshoot air-flow, mix, hold under the arm and wrap up in, the dust cover that blows off is that air water two-phase is spurted.The technical scheme in the invention for solving the technical problem is: through the repeatedly aperture of water delivery/gas transmission, pressure, matching test, the inclined hole of several circumference uniform distribution is devised in nozzle chamber optimization, matching with the contraction channel diameter of intermediate, inclined hole and nozzle-axis angle are 30 °；Nozzle Excircle machining matrix annular groove is to install dust cover, and nozzle its right end face machined seal groove, air inlet matrix grading ring groove；The several inclined holes of the circumference uniform distribution current to entrance nozzle center, carry out multiply air-flow and smash, hold under the arm and wrap up in air water two-phase preshoot, and range is 1.5 times of same pressure single-phase flow shower nozzle；Droplet evenly, finer and closely woven, utilize the dilatancy of compressed gas, make droplet kinetic energy bigger, possess and bigger penetrate thermal current, the ability of fire plumage, the root arriving flame realizes heat absorption, vaporization, quick extinguishing.Dust cover use mold politef, be flush-mounted in the groove of nozzle cylindrical, be matched in clearance with nozzle groove, wind, vibration operating mode under do not fall out；Come off under the pressure of 0.15--0.2MPa.
1) material: nozzle, intermediate, sprayer body, filter screen use low carbon stainless steel, pulverizer plate, clamping screw, nut use copper alloy；Packing ring is red copper；Sealing ring uses nitrile rubber；Dust cover is for molding politef.
2) rated operating pressure: 2.5MPa.
3) seal pressure of sealed core, fittings body: 5.0MPa.
4) working pressure range: 0.8MPa-2.5MPa.
5) flow: 10L/min.
6) effectively jet length: >=6m.
7) fogdrop diameter: Dv0.50=35um；Dv0.99=80um.
8) mounting means: downwards, installing obliquely, installing space is 2.5m-3.5m, setting height(from bottom) 3.5m-6.0m.
