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 bigger than normal, droplet is thick partially; To the heating object, when the large-scale precision member sprays protection,,, cause infringement to the inhomogeneous deformation of protection deposits yields because water smoke drips partially slightly, atomizing is inhomogeneous; Present waterfog head can not dilute hazardous gas such as gas effectively, suppress the practical applications requirement that dust from flying such as coal dust/flour fills the air.
Mostly waterfog head of today is swash plate atomizing structure, and it is inhomogeneous to atomize, atomizing angle: 60 °, 90 °, 120 °; Outlet is opened wide, and dust, greasy dirt and corrosive gas are prone to invade shower nozzle, damage service life.
Mostly present waterfog head is that external screw thread connects, and among transportation, installation process, external screw thread is prone to impaired distortion, causes doing over again, even scraps.
Summary of the invention
For the connecting thread that solves waterfog head is prone to the problem of impaired distortion, dustproof problem not.The utility model provides a kind of high pressure swirl fog-spray nozzle, and profile is pyramid type, adopts the swirling flow atomizing structure; The protrudent sphere filter screen is fixed in the sprayer body water inlet by compressing fastening, and the atomizing core is embedded in the edge cover, and is fastening by lock plunger, and dustproof cap stopper is in the sprayer body spout; Fire water supply forms narrower the cutting sth. askew to bumpy flow in 3 roads through protrudent sphere filter screen, lock plunger, edge cover, the shunting of atomizing core, and fully mixed flow is atomized into fine and closely woven droplet crowd in sprayer body and atomizing core atomization chamber, dashes dust cap, spurts; The high pressure swirl fog-spray nozzle by: sprayer body (7), protrudent sphere filter screen (3), dust cap (1), atomizing core (2), compress buckle (4), lock plunger (5), edge overlaps (6) and forms.
The utility model be achieved in that the high pressure swirl fog-spray nozzle by: sprayer body, protrudent sphere filter screen, dust cap, atomizing core, compress buckle, lock plunger, edge cover forms.The protrudent sphere filter screen is fixed in the sprayer body water inlet by compressing fastening, and the atomizing core is embedded in the edge cover, and is fastening by lock plunger, and dustproof cap stopper is in the sprayer body spout; Fire water supply forms narrower the cutting sth. askew to bumpy flow in 3 roads through protrudent sphere filter screen, lock plunger, edge cover, the shunting of atomizing core, and fully mixed flow is atomized into fine and closely woven droplet crowd in sprayer body and atomizing core atomization chamber, dashes dust cap, spurts.
The beneficial effect of the utility model is: the inhomogeneous deformation problem that has produced when having broken through protection heating object, large-scale precision member; Improved shower nozzle swirling flow atomizing performance, droplet is more evenly distributed, fine and closely woven, improved the efficient of hazardous gas concentration such as dilution gas, strengthened the ability that dust from flying such as coal dust, flour fill the air that suppresses; Avoid receiving dust, greasy dirt and corrosive gas to invade the infringement of shower nozzle, solved the problem of the easy impaired distortion of shower nozzle connecting thread.
