Abstract
The invention discloses a kind of spray heads suitable for perfluor hexanone, including shell, a plurality of spray seam is offered on the shell, the a plurality of spray seam is circumferentially disposed, the spray seam is in tilted layout, the projection head and the tail of adjacent two spray seams in the horizontal plane are overlapped, and the tilt angle of the spray seam is β, then 0 ° of β≤90 ° <.The present invention has many advantages, such as that structure is simple, horizontal plane is interior and covers dead angle without injection.
Description
Technical field
The present invention relates to fire fighting device more particularly to a kind of spray heads suitable for perfluor hexanone.
Background technique
Existing spray head mostly uses out the mode of spray orifice to be sprayed, and the gasification of perfluor hexanone is slow, ejects from spray head
Cheng Zhuzhuan after coming, injection area coverage is smaller, and atomization is not ideal enough, and column injection cannot be overlapped covering, horizontal plane well
It is interior to there is injection covering dead angle, it is unfavorable for guaranteeing blow-off velocity and effect.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, provide that a kind of structure is simple, in horizontal plane
The spray head suitable for perfluor hexanone without injection covering dead angle.
In order to solve the above technical problems, the invention adopts the following technical scheme:
A kind of spray head suitable for perfluor hexanone, including shell offer a plurality of spray seam, a plurality of spray on the shell
Circumferentially disposed, the spray seam inclination arrangement is stitched, the projection head and the tail of adjacent two spray seams in the horizontal plane are overlapped, institute
The tilt angle for stating spray seam is β, then 0 ° of β≤90 ° <.
As a further improvement of the above technical scheme: a plurality of spray seam is evenly distributed in the circumferential direction.
As a further improvement of the above technical scheme: the length that the spray is sewn on inner walls is L1, spray and be sewn on shell
The length of outer wall is L2, then L1< L2。
As a further improvement of the above technical scheme: the shell is equipped with threaded mounting portion.
As a further improvement of the above technical scheme: polygon protrusion is additionally provided on the shell.
Compared with the prior art, the advantages of the present invention are as follows: the spray head disclosed by the invention suitable for perfluor hexanone uses
The spray seam of inclination arrangement is sprayed, and is sprayed compared to using spray orifice, medicament can obtain bigger atomisation area, and adjacent
Two spray slits are overlapped at head and the tail, are covered so that the medicament ejected reaches comprehensive no dead angle in horizontal plane.
Detailed description of the invention
Fig. 1 is the structural schematic diagram for the spray head that the present invention is suitable for perfluor hexanone.
Fig. 2 is the A-A view of Fig. 1.
Fig. 3 is the B direction view of Fig. 1.
Fig. 4 is the C-C view of Fig. 3.
Fig. 5 is the structural schematic diagram for the spray head use state that the present invention is suitable for perfluor hexanone.
Each label indicates in figure: 1, shell；11, threaded mounting portion；12, polygon protrusion；2, spray seam.
Specific embodiment
Below in conjunction with Figure of description and specific embodiment, invention is further described in detail.
Fig. 1 to Fig. 5 shows a kind of embodiment that the present invention is suitable for the spray head of perfluor hexanone, and the present embodiment is suitable for
The spray head of perfluor hexanone, including shell 1 offer a plurality of spray seam 2 on shell 1, and a plurality of spray seam 2 is circumferentially disposed, and spray stitches 2
It is in tilted layout, the projection head and the tail overlapping of adjacent two sprays seam 2 in the horizontal plane (is line segment a in attached drawing 11b1Right end and line segment a2b2
Left end overlapping), the tilt angle of spray seam 2 is β, then 0 ° of β≤90 ° <.
This is suitable for the spray head of perfluor hexanone, is sprayed using the spray seam 2 of inclination arrangement, is sprayed compared to using spray orifice
It penetrates, medicament can obtain bigger atomisation area, and adjacent two sprays seam 2 forms head and the tail and is overlapped, so that the medicament ejected
Reach comprehensive no dead angle in horizontal plane to cover, promotes extinguishing effect.
As a preferred technical solution, in the present embodiment, a plurality of spray seam 2 is evenly distributed in the circumferential direction, is conducive to shell 1
Respectively uniformity is kept to the medicament of ejection.
Further, in this embodiment spray seam 2 is L in the length of 1 inner wall of shell1, length of the spray seam 2 in 1 outer wall of shell
For L2, then L1< L2, namely spray seam 2 is bell-mouth structure of air, so that medicament ejector comes out into sector, atomisation area is further increased,
Further improve the gasification result of medicament.
As a preferred technical solution, in the present embodiment, shell 1 is equipped with threaded mounting portion 11.It can be installed by screw thread
The reliable installation of the realization of portion 11 spray head.
Further, in the present embodiment, polygon protrusion 12 is additionally provided on shell 1, such as to can be regular hexagon convex
Portion convenient for tools such as spanners by 12 clamping shell 1 of polygon protrusion, and then threaded mounting portion 11 and installation interface is tightened.
Although the present invention has been disclosed as a preferred embodiment, however, it is not intended to limit the invention.It is any to be familiar with ability
The technical staff in domain, without deviating from the scope of the technical scheme of the present invention, all using the technology contents pair of the disclosure above
Technical solution of the present invention makes many possible changes and modifications or equivalent example modified to equivalent change.Therefore, all
Without departing from the content of technical solution of the present invention, according to the present invention technical spirit any simple modification made to the above embodiment,
Equivalent variations and modification, all shall fall within the protection scope of the technical scheme of the invention.
