SU9190A1 - Gas burner - Google Patents

Description

The present invention is a simplified Bunsen burner device with grooves on gas and mixing tubes for fixing the relative position of these tubes.

In FIG. 1 shows a top view of the end of a gas pipe crimped from four sides; FIG. 2 front view of the same end; FIG. 3 - section of a gas burner; FIG. 4, 5 and b - three projections of the mixing tube; FIG. 7 - a general view of the modification of the proposed gas burner.

The end of the gas tube B (Fig. 3) is crimped to obtain a cross-shaped or star-shaped cross section (Fig. 2), with the aim of better mixing the exhaust gas with air. In order to obtain a correct hole, the wire that is inserted beforehand into the tube during crimping must have an appropriate cross section. The gas line tube B is inserted with the crimped end into the mixing tube A bent at the end (Fig. 3). To secure the relative position of the tubes, A ch B has a hollow groove b

(Fig. 1), and the tube A is the same groove b (Figs 5 and 6). When the grooves of the tube A and B coincide, they easily enter one into the other, after which, turning slightly the tube B, they clamp it with the internal convex surface of the groove b.

For air inflow, there are holes about (Fig. 4), arranged one above the other so that accidentally spilled into the burner tube the liquid does not clog the tip and freely flow out of the burner. The air flow is reduced by pushing tube B (Fig. 3) inside the burner. When the position of the end of the tube-, ki B, shown in FIG. 3 by a dotted line, the air flow stops altogether. Thus, by pushing or pushing the tube B, it is possible to regulate the flow of air into the burner.

The modification of the burner, at which the bent is not mixed, and the gas pipe 5, is shown in FIG. 7. Regulation of air here is achieved by screwed grooves pressed on the tubes. When turning the tube 4, it is slightly raised or lowered, with the air-guide openings being opened or closed.

The subject of the patent.

Claims (2)

1. A gas burner with a cross-shaped nozzle, characterized in that, in order to regulate / supply air into the mixing tube A provided with air holes in the mixing tube A, this tube is freely pulled over the output crosswise flattened end of the gas tube j8 and both mentioned tubes are equipped the corresponding grooves b and b, in order to fix the mutual position of these tubes by increasing the friction between them. 2 l Modification of a gas burner. According to claim 1 (Fig. 7), characterized in that the touching ends of tubes pushed into one another are supplied on the outer surfaces of the screw grooves corresponding to each other. A FIG 2.
