Description
Technical field
The utility model is related to fire-fighting equipment field, particularly a kind of erect type shower nozzle backwash disk.
Background technology
Upright sprinkler is the important component of automatic sprinkler system, for detecting fire；
Temperature-sensing element ruptures when heated, shower nozzle water spray, so as to control, stamp out a fire.Mainly for the protection of dining room, hotel,
Shop, commercial mansion, warehouse, factory building etc. are light, middle hazard class and grave danger level building.
Wherein erect type shower nozzle backwash disk is then one of vital part of shower nozzle, and whether the manufacture of backwash disk is reasonable, directly
The sprinkling curve and distribution performance of influence shower nozzle are connect, and shower nozzle extinguishing effect is played a decisive role, the now is in the prior art
Erect type shower nozzle backwash disk watering it is not uniform enough, extinguishing effect optimizes not enough.
Utility model content
The problem of existing for prior art, goal of the invention of the present utility model is that providing a kind of and shower nozzle uses cooperatively
After make watering evenly, spraying range is wider, the more preferable erect type shower nozzle backwash disk of extinguishing effect.
To achieve these goals, the technical solution adopted in the utility model is：
A kind of erect type shower nozzle backwash disk, it includes：
Spider, the spider keeps flat setting；
Curved jaws, the curved jaws are circumferentially uniform around the main body panel, and pay obliquely, the horizontal stroke of the curved jaws
Section edges profile is arc.
The setting of the curved jaws of this claw-like paid obliquely of the application, while the cross-sectional edge profile of curved jaws is
Arc, can make shower nozzle water under high pressure upwards spray reflected by spider after, curved jaws play a part of one guiding, can make
It forms " umbrella ", while the setting of cross section arc can make moment of the water behind curved jaws surface, by this arc（It is right
What is answered is namely the outer surface of curved surface）Surface forms the power drawn as opposite direction, the spray of " umbrella " spilt more is divided
Dissipate, watering is evenly, spraying range is wider, extinguishing effect is more preferable.
As preferred scheme of the present utility model, the length that the adjacent curved jaws are paid downwards is different, makes at least same
When form more than two layers " umbrella " watering, watering is evenly, spraying range is wider, extinguishing effect is more preferable.
As preferred scheme of the present utility model, single curved jaws and other curved jaws that it is separated by a setting are downward
The length of expenditure is identical, more than two layers of " umbrella " is sprinkled water and is more likely formed.
As preferred scheme of the present utility model, the curved jaws from the spider towards tiltedly under pay outward, it is curved
The end of bent pawl is ultimately towards vertical direction, prevents water to be guided to the feelings of the final influence spray effect of spider central shaft movement
Condition occurs.
As preferred scheme of the present utility model, the curved jaws upper end cross-sectional area thickness is more than the cross section face of hypomere
Product, after water under high pressure is touched in curved jaws, can produce a vibrations, the curved jaws of hypomere get over detailed rules and regulations vibrations compared to epimere more
Greatly, water droplet more has levels in the watering of formation, make watering evenly, extinguishing effect it is more preferable.
As preferred scheme of the present utility model, the spider is disk, and its center is provided with vertical through hole.
As preferred scheme of the present utility model, the radian all same that all curved jaws are bent towards the through-bore axis,
Adjacent curved jaws are different in the length of the downward expression in the eyes in its end, more than two layers of " umbrella " is sprinkled water and are more likely formed, increase
Plus watering effect.
As preferred scheme of the present utility model, the spider and curved jaws are integrally formed, and bulk strength is higher,
Under the premise of the setting of " the curved jaws upper end cross-sectional area thickness is more than the cross-sectional area of hypomere ", this shake can be effectively prevented
Dynamic be likely to result in curved jaws and the fracture of spider junction, increase overall service life and stability.
The beneficial effects of the utility model are：
Make after being used cooperatively with shower nozzle watering evenly, spraying range is wider, extinguishing effect is more preferable.
Brief description of the drawings

Fig. 2 is side view of the present utility model；
Marked in figure：1- spiders, 2- curved jaws, 3- through holes.
Embodiment
The utility model is described in further detail with reference to embodiment and embodiment.But should not be by this
The scope for being interpreted as the above-mentioned theme of the utility model is only limitted to following embodiment, all to be based on content of the invention institute of the present utility model
The technology of realization belongs to scope of the present utility model.
Embodiment 1
Such as Fig. 1-2, a kind of erect type shower nozzle backwash disk, it includes：
Spider 1, the spider 1 keeps flat setting, and the spider 1 is disk, and its center is provided with vertical
Through hole 3；
Curved jaws 2, the curved jaws 2 are circumferentially uniform around the main body panel, and pay obliquely, the curved jaws 2
Cross-sectional edge profile be arc.
In the present embodiment, the spider 1 and curved jaws 2 are integrally formed（Constituted by copper alloy, and the equal chromium plating in surface）,
The curved jaws 2 from the spider 1 towards tiltedly under pay outward（The quantity of curved jaws 2 is 26 in the present embodiment, is distributed on
Around spider 1）, the end of curved jaws 2 is ultimately towards vertical direction, and the length that the adjacent curved jaws 2 are paid downwards is not
Together, single curved jaws 2 are identical with the length that other curved jaws 2 that it is separated by a setting are paid downwards, in the curved jaws 2
Cross-sectional area thickness is held to be more than the cross-sectional area of hypomere, all curved jaws 2 are homogeneous towards the radian of the axis bending of through hole 3
Together, adjacent curved jaws 2 are different in the length of the downward expression in the eyes in its end, the perpendicular energy where the central axis of institute's through hole 3
It is enough that corresponding curved jaws 2 are divided into two parts, and the projection thickness of curved jaws 2 in the horizontal plane is 1.5mm, adjacent 2
The midpoint of curved jaws 2 to the vertically symmetrical plane of wherein 1 curved jaws 2 distance be 2mm.
