Background technology
Waterfog head among the current national standard GB5135.3-2003 " automatic sprinkler system the 3rd part: waterfog head ", atomizing angle is: 60 °, 90 °, 120 °; Discharge coefficient is: 27,43, and metered flow is 50L/min, 80L/min, flow is on the low side, atomizing angle is big inadequately; Can not satisfy the practical applications requirement of big flow wide-angle protection such as large-scale petroleum chemical equipment, large-scale main power transformer, aircraft/aero-engine testing stand.
Mostly present waterfog head is swash plate atomizing structure and inclined hole atomizing structure, and it is inhomogeneous to atomize; For external screw thread connects, among transportation, installation process, external screw thread is prone to impaired distortion, causes doing over again, even scraps.
Existing waterfog head is cylindrical, and volume is heavy, the waste raw material.
Summary of the invention
Can not protect the connecting thread of the problem of large-scale petroleum chemical equipment, large-scale main power transformer, aircraft/aero-engine testing stand, solution waterfog head to be prone to the problem of impaired distortion, to reduce raw-material consumption in order to break through conventional waterfog head, improve mist and draw effect.The utility model provides a kind of big flow spiral vortex type waterfog head, and profile is pyramid type, adopts vortex atomizing structure, and metered flow reaches 560L/min, and atomizing angle is 150 °, and connecting thread adopts Rc2 " internal thread; The headkerchief and the sprayer body of big flow spiral vortex type waterfog head are screwed, and the atomizing core is tightened against in the headkerchief, and orifice plate is locked in atomizing core inlet with jump ring; Under operating pressure, fire water supply is split into to cut sth. askew and vows with straight, carry out abundant mixed aerosol, and spurt, implement fire extinguishing, control fire by predetermined angular to vortex.Big flow spiral vortex type waterfog head by: sprayer body (1), headkerchief (3), atomizing core (4), O RunddichtringO (2), orifice plate (5), jump ring (6) are formed.
The utility model is achieved in that big flow spiral vortex type waterfog head is made up of sprayer body, headkerchief, atomizing core, O RunddichtringO, orifice plate and jump ring.Adopt vortex atomizing structure, headkerchief and sprayer body are screwed, and the atomizing core is tightened against in the headkerchief, and orifice plate is locked in atomizing core inlet with jump ring; The vortex atomizing is quickened with the fire-fighting current in 4 holes of cutting sth. askew on the atomizing core cylindrical, has promptly reached the effect of abundant atomizing expansion, has possessed suitable momentum forward again; Atomizing core aperture/hole count, deflection angle become certain interactive, restricting relation with its outlet aperture/circular arc, orifice plate aperture; Sprayer body and pipeline adopt internal thread to be connected, avoided transport, the screw thread problem of deformation damage of being collided with among the installation process; Sprayer body adopts coniform, has reduced volume, has reduced raw materials consumption and weight.
The beneficial effect of the utility model is: realized the performance that big flow fully atomizes, wide-angle is evenly spurted; Satisfied large-scale petroleum chemical equipment, large-scale main power transformer, aircraft/aero-engine testing stand etc. have been carried out the fire suppression applications requirement that big flow wide-angle covers; Adopt single shower nozzle just to reach the containment intensity of a fire, rapid effect of putting out a fire to key position; Reduce appearance and size and raw-material consumption, avoided connecting thread to be prone to impaired problem on deformation.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the section of structure of the utility model.
Fig. 2 is the outline drawing of the utility model.
Fig. 3 is the vital part in the utility model: atomizing core figure.
Sprayer body: for coniform, interface thread is Rc2 ", adopt straight thread to be connected with headkerchief, the sealing of O RunddichtringO.Adopt internal thread to be connected with pipeline, avoided transport, the screw thread problem of deformation damage that is subject to collide with among the installation process; Adopt coniformly, reduced volume, reduced raw materials consumption and weight, the flow of not retained water simultaneously, do not cause the flow resistance loss.
The atomizing core: water inlet is provided with the orifice plate draw-in groove; Water inlet end is processed with 3 and tightens counterbore, and cylindrical is processed with 4 holes of cutting sth. askew, and the hole of cutting sth. askew is to outlet 10 ° of lateral deviations and tangent with inner chamber; Current are through the atomizing of atomizing core high speed vortex; Promptly reach the effect of abundant atomizing expansion, possessed suitable momentum forward again, possessed the ability that bigger radius of protection is come suppressing heat air-flow, the containment intensity of a fire; Outlet is for circular-arc, and the outlet cylindrical has been processed straight thread and O RunddichtringO groove.
The technical scheme that its technical problem of the utility model solution is taked is:
