Shape pipe, the second wedge pipe, and two ends respectively with the internal diameter small end of described first wedge pipe and described
The straight tube that the bigger end of internal diameter of two wedge pipes connects, is provided with in the middle part of described straight tube for controlling described straight tube
First control valve of interior flow；The bigger end of internal diameter of described connecting tube and described first wedge pipe passes through method
Orchid connects, and described connecting tube is provided with the second control valve of flow in controlling described connecting tube.
Preferably, described first control valve and described second control valve are divided in described gun barrel and connecting tube
Cutting formation one test chamber, described straight tube is provided with one for detecting described inspection near first wedge pipe one end
The water tester of hydraulic pressure in survey cavity.
Preferably, described second wedge bore small end is provided with a nozzle.
Preferably, the inwall of described first wedge pipe and described second wedge pipe is all axial along described gun barrel
In outer convex.
Preferably, it is provided with seal washer between described connecting tube and described first wedge pipe.
Compared with prior art, this utility model is carried out successively by the first wedge pipe and the second wedge pipe
Supercharging, simultaneously by the cushioning effect of straight tube, is conducive to increasing hydraulic pressure effect, simultaneously by the second control
Valve processed controls to enter the discharge in fire-fighting lance, and is controlled in fire-fighting lance by the first control valve
The discharge of ejection, is conducive to the controllable type of the fire-fighting lance increased.
Accompanying drawing explanation
Fig. 1 is the attachment structure schematic diagram of fire-fighting lance of the present utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with
Drawings and Examples, are further elaborated to this utility model.Should be appreciated that this place is retouched
The specific embodiment stated, only in order to explain this utility model, is not used to limit this utility model.
Referring to Fig. 1, embodiment of the present utility model provides a kind of fire-fighting lance, including a wedge rifle
Pipe 1 and a connecting tube 2, described gun barrel 1 includes the first wedge pipe that internal diameter is gradually reduced the most vertically
11, the second wedge pipe 12, and two ends respectively with the internal diameter small end of described first wedge pipe 12 and described
The straight tube 13 that the bigger end of internal diameter of the second wedge pipe 12 connects, is provided with for controlling in the middle part of described straight tube 13
Make the first control valve 3 of flow in described straight tube 13；Described connecting tube 2 and described first wedge pipe 11
The bigger end of internal diameter by Flange joint, and described connecting tube 2 is provided with for controlling described connecting tube 2
Second control valve 4 of interior flow.
The present embodiment is managed carried out supercharging successively by the first wedge pipe 11 and the second wedge 12, leads to simultaneously
Cross the cushioning effect of straight tube 13, be conducive to increasing hydraulic pressure effect, controlled by the second control valve 4 simultaneously
Enter the discharge in fire-fighting lance, and control ejection in fire-fighting lance by the first control valve 3
Discharge, is conducive to the controllable type of the fire-fighting lance increased.
During concrete operations, can be connected with water band by connecting tube 2, when current enter fire-fighting by water band
After hydraulic giant, current can be controlled by the second control valve 4 and enter the flow of fire-fighting lance, and then control water
The size of pressure, controls the water flow of fire-fighting lance simultaneously by the first control valve 3, to control water spray
Amount size and distance.And in order to increase the sealing between connecting tube 2 and gun barrel 1, the present embodiment exists
It is provided with seal washer 5 between described connecting tube 2 and described first wedge pipe 11.
When specifically arranging, can by the internal diameter of straight tube 13, the first wedge pipe 11 small end internal diameter, second
The wedge pipe 12 bigger end the most identical setting of internal diameter, and first wedge pipe the 11, second wedge pipe 12, straight
Pipe 13 is the most in smoothing junction, to ensure that current smoothly transit in gun barrel 1, reduces in current flow process
