Abstract
The invention provides a nozzle for tire fire extinguishing. The nozzle comprises a nozzle body and a protection cover. The nozzle body is provided with a circular truncated cone with a spray hole and a stepped cylinder longitudinally and sequentially. The protection cover is of a thin-walled structure which is made from a nonmetallic material and equal in the wall thickness. The stepped cylinder longitudinally comprises a large cylinder section, a medium cylinder section and a small cylinder section, the maximum-diameter section is connected with the circular truncated cone, and the minimum-diameter section is located at the tail end of the nozzle body. The stepped cylinder is provided with a mounting thread. A central hole which penetrates through he stepped cylinder and is coaxial with the stepped cylinder is formed in the end face of the bottom of the minimum-diameter section. The protection cover can effectively prevent the spray hole in the nozzle body from being blocked by foreign matter such as slurry, dust and gravel, the interior of the nozzle and a pipeline are kept clean and unobstructed, and reliable operation of the nozzle is ensured; when fire extinguishing agents are sprayed out of the nozzle, the protection cover can be automatically separated from the nozzle body under the action of the fire extinguishing pipeline, other power and extra mechanisms are not needed; and the nozzle is simple in structure, low in cost and high in reliability.

4th optimal technical scheme is that the frustum of a cone top end face and conical surface are distributed with and the stepped cylinder
The spray orifice of body centre bore connection, the spray orifice oral area is provided with chamfering.
5th optimal technical scheme is, the protective cover profile and the nozzle frustum of a cone and maximum gauge section cylinder one
Cause, there are the plane fitted with the nozzle frustum of a cone end face, the protective cover cylindrical section in the protective cover frustum-conical portion inner side
Inner surface is engaged with the nozzle column part.
6th optimal technical scheme is that the protective cover is provided with inwardly protruding with the maximum gauge section cylinder link ends
Circular seamed edge, the internal diameter of the seamed edge is identical with the diameter of the nozzle mid diameter section.
7th optimal technical scheme is that centripetal radial otch, institute are formed with the protective cover cylindrical section and interior lug edge
State that incision length is the protective cover cylinder segment length 2/3, width less than the protective cover wall thickness 1/2.
8th optimal technical scheme is to leave between the protective cover frustum of a cone medial surface and the nozzle frustum-conical surface
Gap, the gap length is the 1/2 of protective cover wall thickness.
With immediate prior art ratio, the present invention provide technical scheme there is following excellent effect：
1st, protective cover can effectively prevent the spray orifice on nozzle by foreign matters from being blocked such as mud, dust and gravels, keep in nozzle
Portion and pipeline are clean, unobstructed, it is ensured that nozzle reliably working.
2nd, when the outside spray fire extinguishing agent of nozzle, protective cover can automatically disengage nozzle, nothing under the effect of fire-fighting pipeline pressure
Need other power and additional mechanism.
3rd, simple structure, with low cost, reliability is high.
