Abstract: This paper presents a new type of fire-fighting water gun. The principle is added storage process before the spray. When the pressure reaches the set value,the mechanical switch will open within a very short of time,then the gun will spray rapidly. When the water pressure less than the set minimum value,the switch can automatically close,the gun will continued storage to increase water pressure. In that way,it made the pressure when spray between 1200 kPa and 450 kPa. Through hydraulic computation,it can be found that the technical parameter of the gun,like the water speed,flow and range are all improved. At the same time,it also increased the fogging degree of the water. This design greatly improved the efficiency of extinguishment.
