The specific embodiment
For those skilled in the art can understand technical scheme provided by the present invention better, set forth below in conjunction with specific embodiment.
Spray gun is used in fire-fighting provided by the invention, is made up of the rifle body and the shower nozzle of inner water flowing, and said 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 said water level transfer valve 2 respectively, and the other end is connected with shower nozzle respectively; The diameter of the delivery port of the nozzle diameter of said gun barrel and said water level transfer valve 2 is complementary.
See also Fig. 1, this figure be in the embodiment of the invention fire-fighting with the sketch map of spray gun.
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 through 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.
