GAS TORCH HEAD, PARTICULARLY FOR A FLAME SCARFING TORCH

摘要

A gas torch head has a nozzle body with a central pipe. According to the invention, the nozzle body (110) comprises internally at least one additional pipe (102, 103) around the central pipe (101) and coaxial therewith, each additional pipe having its own gas supply circuit which is independent of the other supply circuits, discharging at an associated annular orifice (112, 113) coaxial with the main orifice (111) of the central pipe (101), for propelling the gas, if necessary, at different pressures and/or speeds in the same ducted flow, thereby controlling the jet of gas from the nozzle body (110).
