Sucking atomizer for gasoline-oxygen cutting-welding

Abstract

A jet-inducing atomizer for gasoline-oxygen cutting-welding comprises a main body, a diffusion tube, a preheating oxygen fine-tube and a gasoline fine-tube. The diffusion tube and the preheating oxygen fine-tube are provided at the center of the main body co-axially, and communicated with each other. The gasoline fine-tube enters the main body from one side of the main body, and is communicated with the diffusion tube. The diffusion tube is a conical tube. The coarse end of the conical tube is coincidence with the end face of the body. The fine end of the conical tube is connected with the preheating oxygen fine-tube. The advantages of the gasoline-oxygen cutting machine are as follows: the operation is easy as the gasoline tank needs not be pressurized; there is no leak of gasoline or jet of gasoline in leaking manner during operation. The atomized mixture of gasoline and oxygen is immediately jetted while the oxygen valve is opened, and gasoline is immediately shut off while the oxygen valve is closed. Therefore, safety of operation is increased and the cost is reduced.
