Abstract
The utility model provides a water mist spray head, which is closed at other times and is opened for spurting when the inlet water pressure reaches a set value so that water current is brought up into thick water drops less than 400 microns and then the water drops are spurted, and the spray head is automatically closed when the inlet water of the spray head loses pressure. The spray head is composed of a plurality of small nozzles and provided with spring pre-tightened tip cone sealing therein so that the spray head is maintained in a closed state. The constant-pressure spray head for spurting water mist belongs to the fire-fighting field and solves the problems that the outlet of a conventional spray head is normally open; dust and corrosive harmful gas easily invade the spray head and pipe network to damage the service life of the system; the filter screen is planar and has no reinforcing and locking mechanism; and the outlet water at the beginning or end of the spurting is in the form of drops and flowing water, which directly causes water loss and easily generates electric conduction and electric shock. The constant-pressure spray head for spurting water mist is provided with a pre-tightening spring, a tip cone, a dust helmet, a stereo spherical filter screen and the like. The stereo spherical filter screen has a circulation area which is 4 times of that of the planar filter screen, high intensity and impact resistance to high pressure and big water current. The spray head is provided with a pre-tightening closing tip cone, does not discharge water at the beginning or end of the spurting or when the water pressure is low, and is opened only when the water pressure reaches a predetermined water pressure. The spray head spurts water while taking action after the water is atomized through a spray core and a spray nozzle. The dust helmet prevents dust and oil stain from entering the nozzle and accumulating to block the nozzle hole and the spray core.
Description
Technical field
The utility model relates to a kind of fire protection sector of being used for, close at ordinary times, open when intake pressure reaches setting value and spurt, current are resolved into the fine mist spray head that sprays less than the fine and closely woven water droplet of 400um, close voluntarily during shower nozzle inlet decompression, belong to fire-fighting fire extinguishing, control fire, fire prevention field.
Background technology
Existing GB GB5135.5-2003 waterfog head.Rated operating pressure is on the low side, is 0.35MPa; Outlet is often opened; Droplet is thicker, does not have dust cover and filter screen.
Shower nozzle outlet is at present often opened, and dust and corrosivity pernicious gas are easily invaded shower nozzle, pipe network, the infringement lifetime of system.
Do not have dust cover, the dust in the zone of protection, greasy dirt enter nozzle interior, gather plug nozzle hole and atomizing core, influence atomizing effect even spray and lost efficacy.
Filter screen is the plane, and the flow resistance loss is bigger; And do not have the reinforcement locked mechanism, under the high-pressure high-flow water impact, easily stretch and be out of shape, fall apart, stop up atomizing core and nozzle bore.
Do not have spring pretension addendum cone hermetically-sealed construction, water outlet easily produces electric leakage, shock hazard for dripping, drop down water and direct current water arrow under sprinkling beginning/end and low hydraulic pressure.
Summary of the invention
Spraying electric leakage, the shock hazard that dripping under the whole story and the low hydraulic pressure dropped down water, direct current water is vowed and produce in order to solve conventional waterfog head; Spraying core and the susceptible to plugging problem in spray nozzle hole.The utility model provides a kind of level pressure to spurt fine mist spray head, and water inlet is established the spherical filter screen that strengthens, in establish spring pretension addendum cone hermetically-sealed construction, the outlet dust hood of setting up defences.When low hydraulic pressure and the beginning and the ending phase of sprinkling, this shower nozzle is anhydrous to be discharged; Have only when intake pressure reaches scheduled pressure value, just promote spring and open, through spraying core/spray nozzle atomizing ejection.
The utility model is achieved in that level pressure spurts fine mist spray head and strengthen screen pack, body, O RunddichtringO, addendum cone, spring, spraying core, spray nozzle, dust cover etc. by lock plunger, sphere and form.Under initial tension of spring, keep closing sealing state at ordinary times; When beginning to spray, because hydraulic pressure is not increased to the predetermined work force value, shower nozzle is in all the time closes sealing state; When intake pressure reached scheduled pressure value, current promoted spring and open, and through spraying core, spray nozzle atomizing ejection, dust cover comes off simultaneously.Spurt when finishing, when the shower nozzle intake pressure is lower than scheduled pressure value, close automatically, avoided the surplus water in the system pipe network to drop down, drip phenomenon from the shower nozzle long period.
The beneficial effects of the utility model are: eliminated and sprayed beginning/end and following of low hydraulic pressure, dropping down water and direct current water arrow and the electric leakage/shock hazard of generation, the blockage problem of stopped to spray core and spray nozzle.
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: addendum cone figure.
Fig. 4 is the vital part in the utility model: spraying core figure.
The import screen pack: be mold pressing hemispherical stainless steel screen pack, outer perimeter strengthens with the stainless steel sheet| bound edge, Screen pack is intake with lock plunger compression and shower nozzle in the internal channel. Its circulation area is identical order number, identical mouth 4 times of flat screen pack in footpath, anti-high-pressure high-flow water impact is strong, and the flow resistance loss is little.
Dust cover is bright red polytetrafluoroethylene (PTFE), at ordinary times with nozzle cylindrical interference fit, is exporting hydraulic pressure during sprinkling Under come off; Prevent that dust, greasy dirt in the protection zone from entering nozzle interior, gathering plug nozzle hole and atomizing Core affects atomizing effect.
The atomizing core: be made up of the hole of cutting sth. askew on middle part straight hole and the limit, the middle part straight hole is concentric with nozzle bore; Inclined hole with The inward turning hole is tangent, and toward inclined to one side 30 ° of jet hole, formation namely has the vortex atomizing, and oriented front dash is fine and closely woven again The droplet group; This shower nozzle is had than the extinguishing ability of big height with big spacing.
Addendum cone: cover has the O of being risen RunddichtringO, under the thrust of spring, moves to influent side at ordinary times, and the O type is close Seal and body conical sealing seat are in the linear sealing state. The addendum cone influent side is processed as interior concave ball shape, and open at the middle part Groove water conservancy diversion, water outlet side are three-jaw, fixing spring, and the inner via hole road is established at the middle part.
The technical scheme in the invention for solving the technical problem is:
Adopted spring pretension addendum cone hermetically-sealed construction by design in the shower nozzle inner passage, by the atomizing core that the hole of cutting sth. askew on middle part straight hole and the limit is complementary, water inlet is established sphere and is strengthened filter screen, exports the dust hood of setting up defences.
