The extension and retraction of the third electric telescopic rod 19 is used to drive the piston plate 20 to move up and down, thereby controlling the outflow of soapy water.

[0025] In a further preferred embodiment of the present invention, the pressurization component includes an air pump 10 mounted on the support frame 1 and an exhaust pipe 11 fixed to the exhaust end of the air pump 10 and rotatably connected to the adjusting shaft 2.

The gas channel serves as the transmission path for the high-pressure gas, guiding the gas transmitted from the exhaust pipe 11 into the pipeline to achieve pressurization of the pipeline. The one-way valve prevents the gas from flowing back to the air pump 10 during the pressurization process, ensuring the stability and continuity of the pressurization process. The electric valve 12 is used to control the opening and closing of the gas channel, thereby achieving precise adjustment of the internal pressure of the pipeline. By controlling the on / off state of the electric valve 12, the internal pressure level of the pipeline can be adjusted according to the detection requirements.

When the pressure vessel pressure pipeline is placed on the adjusting shaft 2 and the support shaft 3, the sealing gasket 7 on the two protective sleeves 4 will contact both ends of the pipeline respectively. As the adjusting shaft 2 and the support shaft 3 clamp the pipeline, the sealing gasket 7 will be compressed and pressed tightly against the pipeline surface to form a tight seal. During pressurization, the sealing gasket 7 can effectively prevent gas from leaking from both ends of the pipeline, ensuring the stability and accuracy of the pressurization process.

[0031] In a further preferred embodiment of the present invention, a fixing frame 8 is fixed on the support frame 1, a hydraulic rod 24 is fixed on the fixing frame 8, and an extrusion plate 9 for applying external pressure to the pressure pipeline of the pressure vessel is installed on the output rod of the hydraulic rod 24.

The hydraulic rod 24 serves as a power source, and through the extension and retraction of its output rod, it achieves precise control of the position of the extrusion plate 9. The hydraulic rod 24 has the characteristics of high precision, high stability, and easy control, and can meet the requirements of applying external pressure to the pressure vessel and pressure pipeline. The extrusion plate 9 is made of a sturdy and durable material, which can withstand large pressure without deformation or damage. Driven by the hydraulic rod 24, the extrusion plate 9 can apply uniform external pressure to the pipeline to simulate the stress state of the pipeline under actual working conditions.

[0033] In a further preferred embodiment of the present invention, the support frame 1 is provided with an electric guide rail 13 for adjusting the position of the adjusting block 14, the support frame 1 is provided with a battery box 21, and the box body 16 is provided with an isolation net 18 for assisting in dispersing and discharging soap liquid.

[0034] In this embodiment, the electric guide rail 13 is used to adjust the position of the adjusting block 14, which can coat the outer wall of the pressure vessel and pressure pipeline with soapy water. The battery box 21 is used to store the battery that provides power to the device, ensuring that the device can work normally without an external power source.
