Summary of the invention
In order to solve conventional waterfog head, to spurt flow less than normal, the problem that atomization is insufficient, fogdrop diameter is large, jet length is short.The utility model provides a kind of waterfog head, adopts twin-stage vortex atomization structure, and it is cylindric that profile is, atomization core water inlet, center trace keeps concentric with spout, there is chopped-off head, final stage twin-stage vortex atomization runner, vortex atomization runner and endoporus are tangent, while spurting, pressure flow is poured into from the body entrance, be divided into three strands of current: first strand of current is directly by atomization core water inlet, center trace washes away to spout, second strand of current is through chopped-off head vortex atomization runner, enter center trace and be rotated acceleration to the spout diffluence, the 3rd strand of current are by final stage vortex atomization runner, again water flow rotary is accelerated to atomization, through spout, current are decomposed into to fine and closely woven droplet group, by the angle of setting, spray out.The utility model is with a wide range of applications at electric power, boats and ships, chemical industry, refinery device, dangerous material storage tank etc., is particularly suitable for large tracts of land and leaks valve, the joint burnt and the intensity of a fire realization covering compacting with pressure of emergency episode dangerous material exhaust of oil mouth is put out a fire.
The utility model is achieved in that waterfog head is comprised of body (1), O RunddichtringO (2), atomization core (3).The O RunddichtringO is enclosed within the groove of body end face, and the atomization core is connected with body by straight thread, compresses the sealing of O RunddichtringO, while spurting, pressure flow is poured into from the body entrance, be divided into three strands of current: the current of first strand are directly by atomization core water inlet, center trace washes away to spout, the current of second strand are through the chopped-off head vortex atomization runner of atomization core, enter center trace and be rotated acceleration to the spout diffluence, the 3rd strand of current enter final stage vortex atomization runner by the annular space between body and atomization core, again water flow rotary is accelerated to atomization, through spout convergent cone section, straight spout, current are decomposed into to Φ 0.3mm-φ 0.6mm droplet group, being the filled circles taper by 90 ° that set sprays out.
The beneficial effects of the utility model are: realized the large flow of 500L/min, atomization is fine and closely woven evenly, and fogdrop diameter is Φ 0.3mm-φ 0.6mm; Improved the jet length of waterfog head, taken full advantage of hydraulic energy, strengthened the usefulness that waterfog head covers the compacting fire extinguishing, the intensity of a fire with pressure of emergency episode dangerous material exhaust of oil mouth has been realized to the instantaneous effect of putting out.
The 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 outline drawing of the present utility model.
Fig. 3 is the vital part in the utility model: atomization core profile.
The specific embodiment
