[0002] The dual-fluid spray gun is an industrial device that utilizes the synergistic effect of compressed air and liquid media to achieve efficient atomization. It mainly consists of a nozzle, gun body, air-liquid channel and connecting parts. Compressed air and liquid collide and mix multiple times inside the nozzle to form fine and uniform droplets. It is widely used in flue gas treatment, industrial spraying, dust suppression and cooling.

[0003] Currently, the connection between the gun body and the gas-liquid channel is usually made using a flange connection. The gas-liquid pipe and the gun body are first fixed to a flange, then a flange gasket is placed between the two flanges to ensure a seal, and finally the two flanges are tightened with bolts to make them tightly connected. This method is not convenient for quick connection and use.
