Description

A gas distribution device for welding

technical field

The utility model relates to the technical field of welding machine equipment, in particular to a gas distribution device for welding.

Background technique

When the welding machine is working, it usually uses the welding machine to weld the workpiece. Usually, shielding gas is introduced into the welding machine and the welding workpiece to realize the protection during welding. However, the existing welding machine is used for welding. The efficiency of gas supply to the welding machine is not high. The gas source can only supply gas to one welding machine when it is working. When other welding machines are working, other gas sources are required, or the gas source is connected to this welding machine, resulting in Production efficiency is low.

SUMMARY OF THE INVENTION

The purpose of the utility model is to propose a gas distribution device for welding in order to solve the shortcomings existing in the prior art.

In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions: a gas distribution device for welding, comprising a gas source, a welding machine and a welding workpiece, wherein the gas source is respectively connected with the welding machine and the welding workpiece through pipelines, The welding workpiece is set in the welding machine, the pipeline connecting the gas source with the welding machine and the welding workpiece is "Y"-shaped, and between the gas source and the welding machine and between the gas source and the welding workpiece A distributor, a pressure reducing valve is arranged between the air source and the distributor, and a ball valve is arranged between the air source and the pressure reducing valve, the distributor and the welding machine, and the distributor and the welding workpiece.

Preferably, there are three welding and welding workpieces.

Preferably, the pipeline connecting the distributor and the welding machine is further provided with a pressure gauge, and the pipeline connecting the distributor and the welding workpiece is also provided with a flow meter.

Preferably, both of the dispensers are provided with safety valves.

The beneficial effects achieved by the utility model are:

The welding gas distribution device realizes the safety of welding construction through the protection of gas. During welding, the gas flows through the pipeline to the welding workpiece to form a stable protective surface for the welding workpiece, and then starts the welding machine to perform the welding operation on the workpiece. At the same time, it can effectively protect the welding machine, and at the same time, it only needs one gas source to meet the use of shielding gas for multiple welding machines. The distribution of shielding gas through the distributor can meet the overall use of shielding gas for multiple welding workpieces. Can effectively improve production efficiency.

Description of drawings

The accompanying drawings are used to provide a further understanding of the present invention, and constitute a part of the specification, and are used to explain the present invention together with the embodiments of the present invention, and do not constitute a limitation to the present invention. In the attached image:

Fig. 1 is the structural block diagram of the embodiment of the present utility model;

FIG. 2 is a partial connection schematic diagram of an embodiment of the present invention.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Example

As shown in Figures 1-2, the utility model provides a gas distribution device for welding, including a gas source, the gas source is connected with two distributors through a "Y"-shaped pipeline, and the end of the pipeline close to the gas source is installed There is a ball valve, and a pressure reducing valve is installed on the end of the pipeline near the distributor. One distributor has three welding machines connected in parallel through the pipeline, and the other distributor has three welding workpieces connected in parallel through the pipeline. The position of the welding workpiece is at the end of the pipeline. At the gas outlet port, when the shielding gas passes through the pipeline to this point, the shielding gas will form a stable protective surface on the surface of the workpiece. The three welding workpieces are located on the three welding machines respectively, and are installed on the pipeline connecting the distributor and the welding machine. There are pressure gauges and ball valves. Ball valves and flow meters are installed on the pipeline connecting the distributor and the welding workpiece. Safety valves are also installed on both distributors. When the pressure is too high, the safety valve will release the pressure in time to make it within the rated pressure range, effectively ensuring the safe operation of the entire device.

To sum up, when in use, supply air through the air source, open the ball valve and the pressure reducing valve, the shielding gas enters the distributor through the pipeline, the shielding gas passing through one of the distributors enters the welding machine, and passes through the other distributor. The protective gas flows to the welding workpiece to be welded, adjust the flow rate of the protective gas to form a stable protective surface, and then use the welding machine to weld the workpiece.
