Description

Technical Field

[0001] The utility model relates to the technical field of flame welding equipment, in particular to a flame welding device for household air-conditioning pipes. Background Art

[0002] When connecting and extending household air-conditioning pipes, it is often necessary to weld the household air-conditioning pipes, and thus flame welding equipment is required. The utility model patent with patent application number CN201921349960.3 discloses a flame welding device, in which gas flows from a gas cylinder to a gun body, and a flame is formed after the gas is ignited. Since the gas outlet end of the air inlet pipe is respectively connected to the left welding pipe and the right welding pipe, the gas can be divided into two parts from the gas outlet end of the air inlet pipe and enter the left welding pipe and the right welding pipe respectively; that is, a single flame is dispersed into two flames, and the central axes of the left flame outlet and the right flame outlet intersect at one point; so that the two separated flames are ejected The two flames intersect at one point, and the intersection of the flames is used to heat the copper tube, so that the workpiece copper tube is heated evenly, and the flame temperature is high at the intersection, which is conducive to the welding of the copper tube, and the time required for welding is short, and the welding efficiency is high. According to the technical scheme disclosed by the invention, when the existing flame welding equipment is used, on the one hand, when the diameter of the household air-conditioning pipe is large, it is impossible to evenly heat the surrounding area, which may easily cause the temperature around the household air-conditioning pipe to be inconsistent, thereby reducing the welding quality and work efficiency. On the other hand, the flame size cannot be automatically adjusted, which may easily lead to a waste of gas. At the same time, air explosion may easily occur when the fire is turned off, which is not conducive to ensuring the safety of personnel and equipment.
