Novel oxyhydrogen flame gun

Abstract

The invention relates to a novel oxyhydrogen flame gun, belonging to the field of machines. The flame temperature of the existing oxyhydrogen flame guns cannot be freely controlled. The novel oxyhydrogen flame gun comprises a gun barrel, a mixed gas delivery pipe, a gun nozzle fixedly mounted at the front end of the mixed gas delivery pipe, a hydrogen gas inlet pipe, an oxygen gas inlet pipe, a hydrogen gas inlet pipe connector, an oxygen gas inlet pipe connector and a regulating device, wherein the front ends of the hydrogen gas inlet pipe and the oxygen gas inlet pipe are both in sealed connection with the tail end of the regulating device, and the tail ends of the hydrogen gas inlet pipe and the oxygen gas inlet pipe are respectively connected with the hydrogen gas inlet pipe connector and the oxygen gas inlet pipe connector; the tail end of the mixed gas delivery pipe is in sealed connection with the front end of the regulating device; the gun barrel is sleeved outside the hydrogen gas inlet pipe and the oxygen gas inlet pipe and is fixedly mounted on the regulating device; and gas inflows of hydrogen and oxygen gases are respectively regulated through the regulating device, so as to control the mixture ratio of mixed gas of the hydrogen and oxygen gases. After the structure is adopted, the novel oxyhydrogen flame gun can be used for freely and easily regulating the mixture ratio of the mixed gas, and therefore the aim of regulating the flame temperature is achieved.

Description

technical field [0001] The invention belongs to the field of machinery and relates to a welding tool, in particular to a novel hydrogen-oxygen flame gun. Background technique [0002] With the continuous advancement of science and technology, the field of welding has developed rapidly. According to different gas sources, it can be divided into many types. Hydrogen-oxygen welding is one of them. It has the characteristics of high efficiency, safety, energy saving, environmental protection, and convenience. Therefore, it is often used It is used in exquisite items such as gold and silver jewelry. Oxygen-hydrogen flame gun is one of the equipment required for welding oxygen-hydrogen. The existing oxygen-hydrogen flame gun is usually composed of several parts such as gun shaft, nozzle, gun frame, control valve, etc. When applying, first adjust the mixing of hydrogen and oxygen output. Proportion, and then control the size of the output of the hydrogen-oxygen mixture through the...

Problems solved by technology

Oxygen-hydrogen flame gun is one of the equipment required for oxygen-hydrogen welding. The existing oxygen-hydrogen flame gun is usually composed of several major components such as gun shaft, nozzle, gun frame, and control valve. When applying, first adjust the mixing of hydrogen and oxygen output. Proportion, and then through the control valve to control the size of the output of the hydrogen-oxygen mixture, so that people can only control the size of the hydrogen-oxygen flame during welding, but not the temperature of the hydrogen-oxygen flame. Because delicate items such as gold and silver jewelry are very precious, Precious items require delicate welding, and delicate welding must have a suitable flame temperature and flame size, and the temperature of the hydrogen-oxygen flame cannot be controlled at will, which will also lead to the loss of precious items
