The specific embodiment
For those skilled in the art can understand technical scheme provided by the utility model better, set forth below in conjunction with specific embodiment.
The fire-fighting spray gun that the utility model provides is made up of the rifle body and the shower nozzle of inner water flowing, and described rifle body is a multi-tube structure, comprising: the small of the stock 1 is provided with the switch of controlling Inlet and outlet water; Water level transfer valve 2, its water inlet is connected with the delivery port of the small of the stock, is used to switch the direction of current; Article at least two, gun barrel, an end connects the delivery port of described water level transfer valve 2 respectively, and the other end is connected with shower nozzle respectively.
See also Fig. 1, this figure is the schematic diagram that spray gun is used in fire-fighting among the utility model embodiment.
Particularly, the rifle body is a twin-tube type structure, includes two gun barrels, is divided into upper water flowing gun barrel 4 and the next water flowing gun barrel 7.Upper water flowing gun barrel 4 connects air shower nozzle 5, and the next water flowing gun barrel 7 connects two hole shower nozzles 8, and connected mode can be that fixed connection or self-mountable ﹠ dismountuble connect.Different shower nozzles has different ejection functions, and by the switching between the different ejection functions of water level transfer valve 2 realizations.Two hole shower nozzles 8 comprise a plurality of injection orifices, and are rotatable, to switch different ejection functions.
