[0002] The fire water gun is a commonly used instrument in the field of fire protection, which is used to spray water to a distance. When extinguishing a fire, the water nozzle of the fire water gun is fixed, and the water pressure pumped into the water gun is inconvenient to adjust, and it is also relatively fixed. The fire water gun in the prior art cannot adjust the water output according to the usage situation. It is impossible to effectively save water consumption. Therefore, we propose a fire hose nozzle with adjustable water output

Embodiment
[0024]Embodiment: When in use, water enters the water inlet valve body 1 from the water inlet pipe 6, and the sealing valve core 9 is turned upward by turning the rotating wheel 5 and rotating the screw rod 7. Adjusting the upward sealing valve core 9 can not only make the water flow normally but also Water intake can be adjusted, and water enters the fire water gun body 2. When the water output needs to be adjusted, the suitable adjusting disc 12 is selected. The fixed groove 17 is separated, and the movable rod 152 is driven by rotating the roulette 5 to rotate the fixed rod 151, so that the adjusting disc 12 in the middle is rotated, and the magnetic sheet on the adjusting disc 12 in the middle is attracted and fixed with the positioning magnet 13, and the movable rod is released. Rod 152, extension spring 153 drives movable rod 152 to reset, thereby makes fixed disk 16 engage with fixed groove 17, and fixed block 161 snaps in the limit groove of front and rear side, then pu...

The invention discloses a fire-fighting lance capable of adjusting the water yield. The fire-fighting lance capable of adjusting the water yield comprises a water inlet valve body, a fire-fighting lance body, a fire-fighting lance spraying head and a nozzle, wherein an installing sleeve is welded to the left side of an inner cavity of the fire-fighting lance body, adjusting plates are arranged inthe middle and on the right side of the inner cavity of the installing sleeve correspondingly, rotating balls are arranged on the bottoms of the two adjusting plates, the outer wall of a rotating rodis fixedly sleeved with a fixing plate, and water through holes are formed in the two adjusting plates. According to the fire-fighting lance, the two kinds of adjusting plates are arranged, so that magnetic sheets on the needed adjusting plate are attracted and fixed to a positioning magnet, the other adjusting plate is rotated by 180 degrees, a movable rod is loosened, a tension spring drives themovable rod to reset, then the fixing plate is connected with a fixing groove in a clamping fit mode so that the needed adjusting plates can be normally used by clamping a fixing block into limitinggrooves in the left side and the right side, the bore diameters of the water through holes in the two adjusting plates are different, and the number of the water through holes in one adjusting plate is different from that of the water through holes in the other adjusting plate, so that the water yield is different during use, and the requirements of different users are met.
Description
technical field [0001] The invention relates to the technical field of fire-fighting water guns, in particular to a fire-fighting water gun with adjustable water output. Background technique [0002] The fire water gun is a commonly used instrument in the field of fire protection, which is used to spray water to a distance. When extinguishing a fire, the water nozzle of the fire water gun is fixed, and the water pressure pumped into the water gun is inconvenient to adjust, and it is also relatively fixed. The fire water gun in the prior art cannot adjust the water output according to the usage situation. It is impossible to effectively save water consumption. For this reason, we propose a fire hose nozzle with adjustable water output. Contents of the invention [0003] The object of the present invention is to provide a fire water gun with adjustable water output, so as to solve the problems raised in the above-mentioned background technology. [0004] In order to achiev...
