Abstract
PURPOSE: To enable to extinguish a flame while the energy of the flame of backfire is the smallest with a backfire preventing device having comparatively small flame extinguishing capacity by accommodating the backfire preventing device within a torch.
CONSTITUTION: An oxygen gas passage 8 is provided at a central portion in a torch grip 4 and a fuel gas passage 7 is provided around the outer periphery of the oxygen gas passage 8. A permiable backfire extinguishing device 13, formed by a sintered metal and surrounding the passage 8, is provided so at to divide a space between an inlet port 7A and an outlet port 7B of the fuel gas passage 7. Consequently, a backfire distance of a backfire flame may be shortened, therefore, the flame extinguishing capacity and the size of the backfire preventing device may be decreased.
