Oxy-hydrogen gas cutting gun and gun body thereof

Abstract

The invention provides a gun body of an oxy-hydrogen gas cutting gun. The gun body of the oxy-hydrogen gas cutting gun comprises a joint, a low-pressure oxygen pipe, a high-pressure oxygen pipe, an oxy-hydrogen gas pipe, a perforated oxy-hydrogen gas pipe, a cutting torch mounting portion and a cutting torch fastening nut. The joint is provided with a low-pressure oxygen channel, a high-pressure oxygen channel, an oxy-hydrogen gas channel and a perforated oxy-hydrogen gas channel. The low-pressure oxygen pipe, the high-pressure oxygen pipe, the oxy-hydrogen gas pipe and the perforated oxy-hydrogen gas pipe are communicated at outlet sides of the low-pressure oxygen channel, the high-pressure oxygen channel, the oxy-hydrogen gas channel and the perforated oxy-hydrogen gas channel respectively. The cutting torch mounting portion is provided with a circular high-pressure oxygen groove, a circular low-pressure oxygen groove, a circular oxy-hydrogen gas groove and a circular perforated oxy-hydrogen gas groove which are used for forming an air injection channel together with a cutting torch of the oxy-hydrogen gas cutting gun and communicated with the high-pressure oxygen channel, the low-pressure oxygen channel, the oxy-hydrogen gas channel and the perforated oxy-hydrogen gas channel respectively, and a sealing surface is arranged between each two adjacent circular grooves. The cutting torch fastening nut is in threaded fit with a connection end of the cutting torch mounting portion and is used for fixing the cutting torch on the cutting torch mounting portion. By the aid of the gun body, difficulties for cutting openings are overcome. An embodiment of the invention further provides the oxy-hydrogen gas cutting gun comprising the gun body.

Description

technical field [0001] The invention relates to the technical field of gas cutting torches, in particular to a cutting torch and a torch body in which hydrogen-oxygen mixture gas is used as fuel gas, is easy to perforate during working, and prevents backfire explosion. Background technique [0002] At present, with the signing of greenhouse gas emission agreements by major countries in the world, the world has been vigorously developing clean energy in recent years. my country is also implementing energy conservation and emission reduction in a planned way, and has increased investment in scientific research in the field of clean fuels. Especially in the application of electrolysis of water to produce hydrogen and oxygen, my country has been at the forefront of the world, and has begun to be widely used in high-heat industries such as industrial cutting steel and oxygen welding copper, replacing acetylene, benzene, gas, natural gas, and heavy oil. High-pollution, high-emissi...
