Claims

[Scope of utility model registration request]

An electric insulator 5 is interposed between the inner tube 2 for the cut oxygen flow path and the outer tube 4 for the mixed gas flow path, each of which is made of a good electrical conductor, over the entire range except for the tip. A torch head B is attached to the front part and connects to the side part a fuel gas pipe 15, a preheating oxygen pipe 16, and a cutting oxygen pipe 17, which are perpendicular or almost perpendicular to the direction of the axis of the crater a and are parallel or almost parallel to each other. At the rear end, a unit inner tube 10 and a unit outer tube 13, each of which is made of a good electrical conductor and whose respective axes are the same or substantially the same as the direction of extension of the axis a of the crater a, are installed.
The rear end of the inner pipe 2 faces the front part, the cut oxygen pipe 17 is connected to the front part of the unit outer pipe 13, and the unit inner pipe 10 and the unit outer pipe 13 are installed in a state where they communicate and are electrically connected at the rear part, A piezoelectric valve body 27 attached with an adsorption magnet 33 for the magnetic valve seat 25 at the rear of the unit inner tube 10 is attached to the unit inner tube 10, one electrode 28 is always in sliding contact with the inner surface of the unit inner tube 10, and then cut. The valve is opened by pressurizing oxygen, and the other electrode 31 moves forward along the axial direction, and the other electrode 31 connects to the inner tube 2.
When the rear end collides with the rear end and the valve is closed by magnetic attraction when the oxygen supply is cut off and the valve is closed, the piezoelectric valve body 27 is connected to the inside of the unit inner pipe 10 behind it and the inside of the unit ahead of it. A cutting torch that forms a communicating flow path 34.
