Description

The invention relates to gas burning devices and can be used in metallurgy, mass construction and electrical engineering for welding, brazing, heating, cutting, firing metal, as well as for producing reducing gas.

The aim of the invention is to enhance the functionality by providing operation in welding and cutting modes.

Figure 1 shows the proposed device in welding mode, a longitudinal section; in fig. 2 - the same, in the cutting mode; fig.Z - mouthpiece, a general view; FIG. 4 is a view A of FIG. 3.

The burner comprises a head 1 with channels 2 and 3 for supplying oxygen and a combustible mixture, respectively, and 4 mouthpiece 5 and nozzles 6 coaxially mounted with an annular gap. The mouthpiece 5 is tight with a central channel 7 communicated by inclined holes 8 s. an annular gap 4, the Nozzles 6 is mounted with the possibility of longitudinal movement and provided with an annular protrusion 9 on the inner surface, and the outer surface of the mouthpiece 5 is filled with a hexagonal with a conical outlet section 10 and segment projections 11 in ONET oblique holes 8, tightly adjacent to the annular flange 9, the nozzle 6.

Dp fixing a certain position of the nozzle 6 serves as a nut 12.

The operation of the burner in welding mode is as follows.

The nozzles 6 are screwed into the head 1 up to the stop into the conical outlet section 10 of the mouthpiece 5, the openings 8 are opened. The fuel mixture through the channels 3 in the head 1 flows through the channels formed by the annular protrusion 9 of the nozzle 6 and the flat edges of the outer surface of the mouthpiece 5, holes 8 of the latter and further into the central channel 7, at the exit. from which the mixture is ignited, forming a concentrated and focused on the surface of the flame metal being processed. In this case, the valve of the cutting oxygen zakrgg. .

When the burner operates in the cutting mode, the mixture through the channels 3 enters the annular gap 4. In this case, the nozzle 6 is installed in the extreme 1 position of the head, ensuring the opening is blocked. In the annular ledge 9, the nozzle 6. At the exit of the annular gap 4, the mixture ignites . After heating the area to be treated, the cutting oxygen valve opens, which is fed into the central channel 7 of the mouthpiece 5, and the metal is cut.

To obtain reducing gases by converting the gas-oxygen mixture, nozzles 6 are fixed with a nut 12 in such a position that, when the combustible oxygen supply valve is closed, the mixture enters both the annular gap 4 and the central channel 7 of the mouthpiece 5 through inclined holes 8.
