Abstract
The utility model discloses an open spray nozzle and belongs to the field of fire control. The nozzle can decompose water into fogdrops of 400 microns to 800 microns under a working pressure and spraying the fogdrops according to a predetermined atomizing angle, and the maximum horizontal spraying distance is 8 meters. The open spray nozzle solves the problems of no protective measures for the outlet of a general spray nozzle, low intensity of a filtering net, a short spraying distance and the like. The long-range spray nozzle consists of a filtering net, a main body, a vortex machine and a dustproof cover. The vortex machine comprises a central hole and three inclined holes on the periphery; each inclined hole deviates for forming two angles so as to reach effects of atomizing and long-range spraying. The filtering net is punched into a ball convex cylinder with a copper plate, the bottom of the filtering net is semi-spherical,and the filtering net is installed with the main body of the spray nozzle in roll riveting manner, so that the head loss is small and high pressure resistant and large water flow impact resistant capacity is high. The dustproof cover is made of nitrile-butadiene rubber by mould pressing and is frequently sleeved in the outer circular groove at the outlet end of the spray nozzle; the dustproof cover does not fall down when wind blows or in vibration, and the end face of the dustproof cover is not in contact with the spray nozzle so as to prevent bonding; and the dustproof cover can be washed away by spraying at an initial low water pressure. Insects, dusts and greasy dirt are prevented from entering into the spray nozzle. The open spray nozzle has a wide application prospect in power, chemical industry, metallurgy, road tunnel and other fields.
Description
Technical field
The utility model relates to a kind of fire protection sector that is used for, and current are decomposed into the waterfog head of 400um-800um droplet by predetermined atomizing angle ejection, and its maximum jet length reaches 8 meters, belongs to fire-fighting fire extinguishing, control fire, fire prevention field.
Background technology
Existing GB GB5135.5-2003 waterfog head, effectively jet length is shorter, be 3.5-5.0 rice, the guard space of 500KVA, 1000KVA power transformer, vcehicular tunnel is 7 meters, consider the influence of wind speed, barrier etc., such waterfog head can not satisfy the application requirements of large-scale power transformer, vcehicular tunnel etc.; The outlet of GB waterfog head does not have dust cover, and water inlet screen pack intensity is low, flow resistance is big.
Shower nozzle outlet is at present often opened, and insect, dust, dust storm and corrosivity pernicious gas are easily invaded shower nozzle, pipe network, and the infringement lifetime of system influences the atomized spray effect simultaneously.
The screen pack of shower nozzle is flat-faced tube or straight-tube shape at present, and the flow resistance loss is bigger; Under great deal running water impacts, easily torsional deformation, fall apart.
Summary of the invention
Problems such as conventional waterfog head jet length is near in order to solve, no dust cover, screen pack intensity are low.The utility model provides a kind of long drive journey waterfog head, and water inlet is established the protruding cartridge type screen pack of stamping forming ball; Export the dust hood of setting up defences.
The utility model is achieved in that long drive journey waterfog head is made up of body, wortex device, screen pack, dust cover.Particular design and through the wortex device of repetition test, form by three inclined holes that a centre bore and periphery are uniform, inclined hole and wortex device angle are 60 °, and inclined hole is along in the tangent line inclined to one side 12 °, center bore and inclined hole footpath and head body outlet aperture become certain interactive relationship, to reach the effect that water can be vowed that atomizing can be predetermined 60 ° or 90 ° of angles again, spray at a distance.Screen pack adopts the punch forming of half-hard state copper coin, is the protruding cartridge type of ball, the uniform aperture in bottom and side, screen pack and head body roll riveting, compression fit, intensity height; The protruding side of ball is towards water inlet, and flow resistance is little.Dust cover adopts the butyronitrile rubber mold pressing to form, be fastened at ordinary times in the shower nozzle outlet side peripheral groove, can in groove, turn round, wind and vibration dust cover can not drop, the dust cover end face does not contact at ordinary times with the shower nozzle exit end face, in case the anchoring effect in the long-term use, dust cover comes off during to 0.1MPa voluntarily at intake pressure.
The beneficial effects of the utility model are: the problem that has improved the remote injection of shower nozzle; Improve the intensity of screen pack, reduced the flow resistance loss; Shower nozzle outlet is protected, and fire-fighting protection reliability, the security to outdoor large power transformer etc. improves greatly especially.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a section of structure of the present utility model.
Fig. 2 is an outline drawing of the present utility model.
Fig. 3 is the vital part in the utility model: wortex device figure.
Screen pack: adopt the punch forming of half-hard state copper coin, be the protruding cartridge type of ball, the uniform aperture in bottom and side, screen pack and head body roll riveting, compression fit, intensity height; The protruding side of ball is towards water inlet, and flow resistance is little.Its three-dimensional circulation area is 5 times of flat screen pack of identical order number, identical bore, and anti-high-pressure high-flow water impact is strong, and the flow resistance loss is little.
The mold pressing of dust cover butyronitrile rubber forms, be fastened at ordinary times in the shower nozzle outlet side peripheral groove, can in groove, turn round, wind and vibration dust cover can not drop, the dust cover end face does not contact at ordinary times with the shower nozzle exit end face, in case the anchoring effect in the long-term use, dust cover comes off during to 0.1MPa voluntarily at intake pressure.
Wortex device: form by three inclined holes that a centre bore and periphery are uniform, inclined hole deflection has two angles, center bore and inclined hole footpath and head body outlet aperture become certain interactive relationship, can atomize and can be with predetermined 60 ° or 90 ° of angles, the effect of spraying at a distance to reach.
The technical scheme in the invention for solving the technical problem is:
Press the core component of this shower nozzle of hydrodynamics three dimensional design--wortex device, and test correction repeatedly under minimum operating pressure, rated operating pressure, maximum working pressure, the atomizing core that this wortex device is complementary by three holes of evenly arranging of cutting sth. askew of middle part straight hole and periphery, center bore becomes certain interactive, restriction relation with inclined hole footpath and head body outlet aperture.Water inlet is established the protruding cartridge type screen pack of ball, exports the dust hood of setting up defences.
