Description

Technical Field

[0001] The utility model belongs to the field of compressors, and in particular relates to an argon compressor test control device. Background Art

[0002] Argon compressors are devices that compress, boost, and recover argon. The compressor compresses the argon into a high-pressure state, then cools the high-temperature compressed argon into liquid form through a cooling system. Finally, the filtration system removes impurities from the argon, allowing the argon to be recovered and reused.

[0003] After the production and processing of the argon compressor is completed, it is necessary to conduct a test run to check whether the compressor is qualified. Before the test starts, it is necessary to provide the argon compressor with a gas source. However, the gas volume required by the argon compressor is different, so at the gas source, it is necessary to purchase a matching valve according to the gas volume of the argon compressor to control the gas intake. Since the gas volume of the argon compressor is inconsistent, it is necessary to purchase and replace the corresponding valve to match the compressor with the corresponding gas volume for use during the test, which not only increases the test cost, but also increases the test steps, making the test process more cumbersome. Utility Model Content

[0004] In response to the problems in the related art, the present invention proposes an argon compressor test control device to overcome the above technical problems existing in the existing related art.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is an argon compressor test control device, comprising a gas supply pipeline connected between an argon gas source and an argon compressor, and a gas supply control valve installed on the gas supply pipeline;

[0007] A branch pipeline is connected in parallel to the gas supply pipeline, and the connection points between the two ends of the branch pipeline and the gas supply pipeline are respectively located on both sides of the gas supply control valve, and a branch pipeline control valve is installed on the branch pipeline.

[0008] Furthermore, the argon gas source is an argon high-pressure storage tank.

[0009] Furthermore, the air supply control valve is a manual needle valve.

[0010] Furthermore, the branch pipeline control valve is an electric needle valve.

[0011] Furthermore, the valve flow rate of the air supply control valve is 100m 3 / min, the valve flow rate of the branch pipeline control valve is 200m 3 / min.

[0012] The utility model has the following beneficial effects:

[0013] 1. In the utility model, when testing multiple argon compressors with different gas volumes, a manual valve is added at the gas source and an electric valve is connected in parallel. By controlling the opening and closing of the manual valve and the electric valve, the gas supply test of three argon compressors with different gas volumes can be carried out. This not only reduces the number of valves used and the cost of testing, but also eliminates the need to disassemble and replace valves with different flow rates during the test, making the test process more convenient and quick.

[0014] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
