Description
Technical Field
The utility model relates to a rotatory watering shower nozzle is used in the fire control, especially a from rotatory watering shower nozzle of speed reduction.
Background
At present traditional fire control is with rotatory watering shower nozzle, carry out autogyration through hydraulic effect, in order to reach the effect that enlarges the area of spraying, the operating pressure of the rotatory watering shower nozzle of tradition is usually between 0.2 MPa-0.5 MPa, nevertheless discover in the in-service use, along with hydraulic increase, the rotational speed of the rotatory watering shower nozzle of tradition can increase rapidly, when spraying water under 0.4MPa operating pressure, atomization phenomenon begins obviously, has seriously influenced the water spray effect during 0.5MPa operating pressure. Along with the pressure rise, the atomization phenomenon becomes more and more serious, the high-speed rotation of the spray head enables a white water mist bag to be generated around the spray head, and most of sprayed water forms water mist in the range of the water mist bag and cannot be sprayed to a larger range. This makes the shower nozzle water spray inhomogeneous, spray radius and water droplet granule diminish, and then has influenced the fire extinguishing effect of shower nozzle.
Aiming at the problem, through repeated research and experiments, a self-decelerating rotary sprinkling nozzle is developed, the influence of the rising of the working pressure of the nozzle on the sprinkling effect is solved, the normal sprinkling form of the nozzle can be ensured under the pressure of 0.7MPa, and the ratio of large-particle water drops with the diameter of more than or equal to 3mm is more than 90%.
Disclosure of Invention
In order to solve the problem, the utility model provides a large granule, large-traffic, efficient watering shower nozzle.
The utility model adopts the technical proposal that:
from rotatory watering shower nozzle of speed reduction, including inlet tube, shower nozzle lid, shower nozzle end and hole for water spraying, at the bottom of the shower nozzle lid below is provided with the shower nozzle, bottom surface and side equidistant hole for water spraying that are provided with at the bottom of the shower nozzle, bottom surface equidistant hole for water spraying that is provided with of bottom surface at the bottom of the shower nozzle.
The spray nozzle bottom is provided with 3 water spray holes which are formed by communicating the bottom surface of the spray nozzle bottom with the open holes on the side surface, and each water spray hole corresponds to 1 damping water spray hole.
The opening direction of the water spray hole on the bottom surface of the spray head bottom and the opening direction of the damping water spray hole on the bottom surface of the spray head bottom are opposite.
The damping water spray hole is in a strip shape.
The utility model discloses the advantage and the effect that have: the damping hole for water spraying can produce reaction force through water pressure, guarantees that rotatory watering shower nozzle can not improve rotation rate fast under the condition that water pressure increases, and the rotation rate of control shower nozzle is in reasonable within range to guaranteed that the water spray is even not atomizing, spray radius is big, and the water droplet granule is big, and the scene of a fire penetrating power is strong, and the speed of putting out a fire is faster, and the space of being suitable for is bigger, and the range of application is wider, has improved the engineering suitability, has the significance in the automatic water spray field of putting out a fire in big space.

Detailed Description
Example 1
As shown in fig. 1 and 2, the nozzle is composed of a nozzle cover 3 and a nozzle bottom 6, the water inlet pipe 1 is movably arranged above the nozzle cover 3, when the nozzle works, water flows into the nozzle through the water inlet pipe 1 and then is sprayed out from the damping water spraying holes 8 and the water spraying holes 9, and the nozzle starts to rotate under the action of water pressure because the nozzle and the water inlet pipe 1 are movably connected by a bearing; the water spray holes 9 are provided with holes on the side surface and the bottom of the nozzle bottom 6, so that the sprayed water covers the whole protection area of the nozzle, and the water sprayed by the damping water spray holes 8 covers the area with a certain radius range around the nozzle, so as to effectively supplement the water spray holes 9. Because damping hole for water spraying 8 and 9 subtend settings, at the in-process that rotates to spray, produced the effort of mutual reversal through water pressure, guarantee that the shower nozzle can not improve rotational speed fast under the condition that water pressure increases, the rotational speed of control shower nozzle is at reasonable within range, thereby guarantee that rivers atomization phenomenon can not appear, can spout evenly not atomizing, the spray radius is big, the water droplet granule is big, the strong rivers of scene of a fire penetrating power, the direct burning thing surface, in order to reach the purpose of putting out a fire fast.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
