The utility model is achieved through the following technical solutions: a kind of multi-functional quick switching fire-fighting spray gun, comprise gun platform, it is characterized in that: the outlet of described gun platform is connected with by hydraulic quick coupler can be with respect to the swivel head of gun platform rotation, described hydraulic quick coupler one end is fixedlyed connected with the outlet of gun platform, the other end and swivel head are rotationally connected, swivel head is connected with a quick transfer valve, the a plurality of jets that are provided with water chamber in the described quick transfer valve and are connected with water chamber, be provided with in the water chamber with respect to the rotatable spool of valve body, spool is for lacking the circle structure, spool is provided with the counterweight roller, and this counterweight roller makes valve body have at least a jet to be positioned at the indentation, there of spool all the time.
In order to solve the problems of the technologies described above, the utility model adopts following further technical scheme:
Described quick transfer valve also is provided with end cap and valve seat, one end of end cap is threaded with swivel head, the other end is threaded with valve seat, described water chamber is located at end cap and valve base chamber, end cap is provided with the straight channel that is communicated with water chamber, described jet is located on the valve seat, and described spool is rotationally connected by bearing pin and valve seat.
Described jet is three, and three jets are triangular arranged.
Described three jets are connected with foam lance, long-range water column spray gun, fine water fog spraying gun respectively.
Described counterweight roller be installed on spool under.
The utility model compared with prior art has following technique effect:
Spray gun of the present utility model has a plurality of jets, integrated multiple fire-fighting modes such as foam fire-fighting, fine mist fire-fighting, long-range water column fire extinguishing, and can switch fast, make a kind of spray gun can put out the polytype fire, alleviated equipment weight, improve the fire-fighting fire extinguishing ability of single vehicle, easy to use, can make the fire fighter arrive the scene of fire fast and according to fire type, switch rapidly and select suitable fire-fighting mode, help holding best fire extinguishing opportunity, reduce the loss that fire causes.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Referring to Fig. 1, Fig. 2 and Fig. 3, the utility model comprises gun platform 1, the outlet of gun platform 1 is connected with by hydraulic quick coupler 2 can be with respect to the swivel head 3 of gun platform 1 rotation, hydraulic quick coupler 2 one ends can be fixedlyed connected by modes such as screw threads with the outlet of gun platform 1, the other end and swivel head 3 can be rotationally connected by modes such as screw threads, swivel head 3 is connected with a quick transfer valve 4, fast a plurality of jets 6 that are provided with water chamber 5 and are connected with water chamber 5 in the transfer valve 4.Quick transfer valve comprises end cap 7 in the present embodiment, valve seat 8 and spool 9, one end of end cap 7 is threaded with swivel head 3, the other end is threaded with valve seat 8, water chamber 5 can be located at 8 of end cap 7 and valve seats, end cap 7 is provided with the straight channel 10 that is communicated with water chamber 5, jet 6 is located on the valve seat 8, spool 9 is positioned at water chamber 5, can rotate with respect to valve body, spool 9 is rotationally connected by bearing pin 11 and valve seat 8, and spool 9 is for lacking the circle structure, and spool 9 is provided with counterweight roller 12, counterweight roller 12 can by modes such as screw be installed in spool 9 under, this counterweight roller 12 makes valve body have at least a jet 6 to be positioned at the indentation, there of spool 9 all the time.Be provided with sleeve 13 outside hydraulic quick coupler 2 and the swivel head 3, sleeve 13 is threaded with end cap 7, and it is armed that the effect of sleeve 13 is to be convenient to both hands.
See Fig. 3 again, the quantity of jet 6 can be provided with as required, the quantity of jet is three in the present embodiment, and three jets are triangular arranged, and these three jets can be connected with foam lance 14, long-range water column spray gun 15, fine water fog spraying gun 16 respectively by screw thread.When pulling spray gun trigger, extinguishing fluid enters hydraulic quick coupler 2-swivel joint 3-quick transfer valve 4-any spray gun successively by the runner of gun platform 1.Foam fire-fighting, fine mist fire-fighting, the handoff procedure of three kinds of fire-fighting modes of long-range water column fire extinguishing is: according to fire type, select suitable fire-fighting mode, rotate quick transfer valve 4, because the existence of swivel joint 3, gun platform 1 is rotated thereupon together, but three spray gun and quick transfer valve 4 for being threaded, therefore, three spray guns can rotate thereupon, suitable lance ejection mouth rotated to be positioned at the equilateral triangle peak, rotary spool 9 in the at this moment quick transfer valve 4 is owing to be equipped with counterweight roller 12 under it, make the whole center of gravity of rotary spool 9 and counterweight roller 12 not overlap with pivot, therefore no matter rotary spool 9 is in the arbitrary initial position, but owing to center of gravity does not overlap with pivot, under the effect of gravity, rotary spool 9 finally all will be in minimum equilbrium position.Because rotary spool 9 is for lacking toroidal, when it is in minimum equilbrium position, counterweight roller 12 makes valve body have at least a jet 6 to be positioned at the indentation, there of spool 9 all the time, and rotary spool 9 will block two other jet that is positioned at end points place, equilateral triangle two base angle simultaneously, the jet that only is in the equilateral triangle peak remains unimpeded, extinguishing fluid passes through unimpeded jet to spray gun, by rotating different lance ejection mouths, realize the quick switching between the different fire-fighting modes in the position of triangle peak.
Although relate to a kind of multi-functional quick switching fire-fighting spray gun and carried out special description disclosed with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
