Abstract
The utility model discloses a water mist spray head with a large spray range, which comprises a spray head seat, an atomization plate and a protection cover, wherein a central shaft hole of the spray head seat is a water flow channel, the protection cover is fixed at an inlet of the water flow channel, an outlet of the water flow channel is contracted and then expanded to form a main spray hole of the spray head, and the atomization plate is fixed in the water flow channel. The water mist spray head is characterized in that at least two rows of circumferentially-distributed inclined spray holes are formed in the inner hole wall of the water flow channel close to the outlet, and the hole diameter of each inclined spray hole is greater inside and less outside. The water mist spray head disclosed by the utility model is of a simple structure; compared with a traditional water mist spray head, the water mist spray head disclosed by the utility model has a larger extinguishment range and can better control the fire behavior and put out a fire.
Description
[technical field]
The utility model relates to building fire protection facility technical field, is specifically related to the waterfog head in a kind of automatic water atomization fire-extinguishing system.
[background technology]
Waterfog head is mainly used in the automatic water atomization fire-extinguishing system in building fire protection facility, waterfog head is a kind of water inlet and delivery port centrifugal atomizing nozzle point-blank, this kind of waterfog head is that the current of certain pressure are resolved into two strands of current, one is move and have the rotary water current of centrifugal speed along inwall, another strand is the straight current with axial velocity, two strands of current converge at the nozzle of shower nozzle, with its aggregate velocity, by spout, sprayed and form atomization, the water smoke of ejection is more even, according to certain atomizing angle, be ejected into equably on the outer surface of protected object, to reach cooling and to suffocate, control fire and stamp out a fire.But traditional waterfog head only has a main jet perforation, fire extinguishing scope is less, although there are at present some waterfog heads to improve, this waterfog head structure after entering is more complicated.
[summary of the invention]
For the deficiency of background technology, problem to be solved in the utility model is to provide a kind of simple in structure, the large spray regime waterfog head that has larger fire extinguishing scope, can suppress better the intensity of a fire and put out a fire.
For solving the problems of the technologies described above, the utility model takes following technical scheme to complete:
Large spray regime waterfog head, comprise nozzle boss, pulverizer plate and protective cover, the central shaft hole that nozzle boss is provided with is water stream channel, protective cover is fixed on the import of water stream channel, the outlet of water stream channel expands the main jet perforation that forms shower nozzle again after shrinking, pulverizer plate is fixed in water stream channel, it is characterized in that: water stream channel is provided with near the inner hole wall of outlet the tilting spray-hole of at least two rows that circumference is laid.
The large spray regime waterfog head that the utility model provides, tilting spray-hole directly processes on nozzle boss body, make simple in structure, the main jet perforation that not only utilizes traditional sprinkler heads to have during work carries out water mist spray, utilize the tilting spray-hole of many rows to carry out water mist spray simultaneously, the tilting spray-hole of many rows is set to be compared the great advantage that the tilting spray-hole of a row is set and is: spray regime is wider, and water sprinkler discharge density is larger, is more conducive to fire extinguishing.Owing to having realized the combined jet of main jet perforation and the tilting spray-hole of many rows, make fire extinguishing scope of the present utility model more extensive, thereby can suppress better the intensity of a fire and put out a fire.Operation principle is: when having fire to occur, press water enters water stream channel after by protective cover, after pulverizer plate, one current move and become the rotary water current with centrifugal speed along water stream channel inner hole wall, another strand of current become the straight current with axial velocity, and these two strands of current converge at the nozzle of shower nozzle, sprayed and form atomization with its aggregate velocity by main jet perforation, meanwhile, also have one current directly by the tilting spray-hole of many rows, to spray fast.
Large outer little in the aperture of tilting spray-hole.Above-mentioned design can make to spray great efforts.
[accompanying drawing explanation]
The utility model has following accompanying drawing:
Fig. 1 is cut-away view of the present utility model.
[specific embodiment]
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail:
As shown in Figure 1, this kind of large spray regime waterfog head, comprise nozzle boss 4, pulverizer plate 5 and protective cover 6, the central shaft hole that nozzle boss 4 is provided with is water stream channel 3, protective cover 6 is fixed on the import of water stream channel 3, and the outlet of water stream channel 3 expands the main jet perforation 1 that forms shower nozzle again after shrinking, and pulverizer plate 5 is fixed in water stream channel 3, water stream channel 3 is provided with near the inner hole wall of outlet the tilting spray-hole 2 of two rows that circumference is laid, large outer little in the aperture of tilting spray-hole 2.
Claims (2)
1. large spray regime waterfog head, comprise nozzle boss, pulverizer plate and protective cover, the central shaft hole that nozzle boss is provided with is water stream channel, protective cover is fixed on the import of water stream channel, the outlet of water stream channel expands the main jet perforation that forms shower nozzle again after shrinking, pulverizer plate is fixed in water stream channel, it is characterized in that: water stream channel is provided with near the inner hole wall of outlet the tilting spray-hole of at least two rows that circumference is laid.
2. large spray regime waterfog head as claimed in claim 1, is characterized in that: large outer little in the aperture of tilting spray-hole.
