Abstract
The utility model discloses a kind of flow guide sleeve applied in fire monitor, including annular flow guiding head and the connecting cylinder that is fixedly connected in annular flow guiding head；The top of annular flow guiding head is equipped with the inclined inclined surface of ecto-entad, and inclined surface is equipped with several radially distributed air conducting grids.This flow guide sleeve can ensure project water column cross sectional shape journey disc and uniformly, effectively ensure that the water column of range and injection will not be easy to scatter to certain distance, reduction water column and air friction coefficient, to improve the applicable efficiency of fire monitor.
Description
Technical field
The utility model is related to a kind of fire monitor accessory technology more particularly to a kind of improving leading for fire monitor range and flow
Stream set.
Background technology
Currently, fire monitor is the important fire-fighting equipment to fight a fire at a distance.Fire water monitor is using water as medium, at a distance
The fire-extinguishing apparatus to stamp out a fire.The big gun is suitable for the places such as petrochemical enterprise, tank area, hangar, warehouse, port and pier,
The even more ideal truck pipe of fire fighting truck.
Accessory of the flow guide sleeve as fire monitor has the function of certain water conservancy diversion spray, but existing water conservancy diversion effect is not
Obviously, it has the following defects：Not enough ensure project water column cross sectional shape journey disc and uniformly, cannot effectively protect range and injection
Water column will not be easy to scatter to certain distance, therefore the applicable efficiency of fire monitor cannot be improved.
Utility model content
For overcome the deficiencies in the prior art, leading in fire monitor is applied the purpose of this utility model is to provide a kind of
Stream set.This flow guide sleeve can ensure project water column cross sectional shape journey disc and uniformly, effectively ensure range and the water of injection
Column will not be easy to scatter to certain distance, the friction coefficient of water column and air be reduced, to improve the applicable efficiency of fire monitor.
The purpose of this utility model adopts the following technical scheme that realization：A kind of flow guide sleeve applied in fire monitor, including
Annular flow guiding head and the connecting cylinder being fixedly connected in annular flow guiding head；Incline equipped with ecto-entad at the top of the annular flow guiding head
Oblique inclined surface, inclined surface are equipped with several radially distributed air conducting grids.
Further, every equal ecto-entad of air conducting grid is obliquely installed.
Further, the quantity of the air conducting grid is 20-60 items.
Further, the inner wall of the annular flow guiding head is equipped with annular groove, the outer wall of the connecting cylinder be equipped with it is described
The limit chuck that annular groove cooperation fastens；The annular flow guiding head is arranged simultaneously by the cooperation of limit chuck and annular groove
It is fixed on the outer wall for being fixedly connected with cylinder.
Further, the outer wall of the annular flow guiding head is equipped with semi-cylindrical reinforcing rib.
Further, the quantity of the reinforcing rib is 8-16 roots.
Compared with prior art, the beneficial effects of the utility model are：
Air flow property is considered when water conservancy diversion Analysis of Nested Design, and intilted grid, fire water are equipped on the top of flow guiding head
When spraying water working condition, the air-flow of surrounding can collect big gun in outlet minimum point, then flow along the direction of flow, lead at this time
The effect of stream set is that the air of its surrounding is directed to its inner cavity water column intersection, the at this time air pressure of inner cavity by inclined grid
It is bigger than its external pressure, air pressure inside can the surrounding of water column formed one layer of air-flow protection film, as water column after ejection not
Meeting journey dispersion shape, reduces the friction coefficient of water column and air, finally makes the range of fire monitor farther, reach the water of appointed place
Increase, to improve the applicable efficiency of fire monitor.
Description of the drawings
Fig. 1 is the structural schematic diagram that the flow guide sleeve in fire monitor is applied in the utility model preferred embodiment；
Fig. 2 is the schematic cross-section of flow guide sleeve.
In figure：1, annular flow guiding head；11, inclined surface；12, air conducting grid；13, annular groove；14, semi-cylindrical adds
Strengthening tendons；2, connecting cylinder；21, chuck is limited.
Specific implementation mode
In the following, in conjunction with attached drawing and specific implementation mode, the utility model is described further, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
As shown in Figs. 1-2, a kind of flow guide sleeve applied in fire monitor, including annular flow guiding head and 1 are fixedly connected on ring
Connecting cylinder 2 in shape flow guiding head；The top of the annular flow guiding head is equipped with the inclined inclined surface 11 of ecto-entad, is set on inclined surface
There are several radially distributed air conducting grids 12.
Air flow property is considered when water conservancy diversion Analysis of Nested Design, and intilted grid, fire water are equipped on the top of flow guiding head
When spraying water working condition, the air-flow of surrounding can collect big gun in outlet minimum point, then flow along the direction of flow, lead at this time
The effect of stream set is that the air of its surrounding is directed to its inner cavity water column intersection, the at this time air pressure of inner cavity by inclined grid
It is bigger than its external pressure, air pressure inside can the surrounding of water column formed one layer of air-flow protection film, as water column after ejection not
Meeting journey dispersion shape, reduces the friction coefficient of water column and air, finally makes the range of fire monitor farther, reach the water of appointed place
Increase, to improve the applicable efficiency of fire monitor.
As the application preferred embodiment, every equal ecto-entad of air conducting grid is obliquely installed.The air is led
The quantity for flowing grid is 20-60 items.The quantity of air conducting grid is selected according to the size specification of fire monitor, to choose energy
It is final purpose enough to make the range of fire monitor farther.
Annular flow guiding head and connecting cylinder are fixedly connected there are many kinds of modes, can be threadedly coupled, snap connection or
One kind in interference fit connection etc..As the application preferred embodiment, the inner wall of the annular flow guiding head is equipped with annular groove 13,
The outer wall of the connecting cylinder is equipped with the limit chuck 21 fastened with annular groove cooperation；The annular flow guiding head passes through limit
The cooperation of chuck and annular groove is arranged and is fixed on the outer wall for being fixedly connected with cylinder.
As the application preferred embodiment, the outer wall of the annular flow guiding head is equipped with semi-cylindrical reinforcing rib 14.It is described to add
The quantity of strengthening tendons is 8-16 roots.On the one hand the design of reinforcing rib is conducive to prevent damaged in collision, on the other hand increase aesthetic sight
Reward property.
The above embodiment is only preferred embodiments of the present invention, cannot be protected with this to limit the utility model
Range, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacing belongs to
In the utility model range claimed.
