Abstract
The invention relates to an anti-backfire gas cutting gun, in particular to an anti-backfire gas-cutting cutting torch. The anti-backfire gas-cutting cutting torch comprises an injecting-type cutting torch model, a thermal switch located on a cutting oxygen pipe of the injecting-type cutting torch model, a control device located at the right side of the thermal switch and an air flow control valve fixed to the right end of the cutting oxygen pipe of the injecting-type cutting torch model. The thermal switch comprises a first connecting piece and a second connecting piece. A gap is formed between the lower portion of the first connecting piece and the lower portion of the second connecting piece. When a backfire phenomenon occurs, the lower portion of the first connecting piece and the lower portion of the second connecting piece can be connected, so that the gap can vanish. Insulating films are arranged on the first connecting piece, the second connecting piece and the contacting portion between the first connecting piece and the second connecting piece. An insulating film is further arranged on the contacting portion between the thermal switch and the cutting oxygen pipe. The insulating film enables the first connecting piece and the second connecting piece to be in a noncommunicating state when backfire does not occur.
