[0013] 3. In the example of the adjustable X-ray transillumination device for small-diameter pipe welds of the present invention, when the positioning plate moves up, the sealing plug installed at the end of the positioning rod squeezes the air in the mounting tube and ejects it through the air jet pipe. The air jet from the air jet pipe acts on the detection end of the pipeline X-ray flaw detection component to clean the foreign matter on the detection end, so as to prevent the foreign matter from adhering to the detection end of the pipeline X-ray flaw detection component and affecting its subsequent use.

[0014] 4.

[0027] When using:

[0028] By controlling the driving motor 4 to drive the adjusting rod 3 to rotate, the threaded barrel 6 drives the movable plates 5 provided at both ends of the adjusting rod 3 to move under the action of the thread on the side of the adjusting rod 3, so that the distance between the two movable plates 5 changes. When the distance between the two movable plates 5 decreases, the positioning plate 8 drives the pipeline X-ray flaw detection assembly 9 to move downward under the action of the connecting plate 7, so that the pipeline X-ray flaw detection assembly 9 can approach the pipeline for inspection, thereby ensuring the quality of pipeline preparation;

[0029] When the distance between the two movable plates 5 increases, the positioning plate 8 drives the pipeline X-ray flaw detection component 9 to move upward under the action of the connecting plate 7, so that the pipeline X-ray flaw detection component 9 is away from the pipeline, so that the position of the pipeline X-ray flaw detection component 9 can be changed to detect other parts of the pipeline, or the pipeline to be inspected can be replaced, which is convenient for the use of the device;
