Description
Technical Field
[0001] The utility model relates to the technical field of pressure pipeline detection, in particular to a nondestructive detection instrument for pressure pipelines. Background Art
[0002] Pressure pipeline refers to all pipelines that are subjected to internal or external pressure, regardless of the medium inside the pipe. Pressure pipeline is a part of the pipeline. The pipeline is used to transport, distribute, mix, separate, discharge, measure, control and stop the flow of fluids. It is an assembly composed of pipes, pipe fittings, flanges, bolted connections, gaskets, valves, other components or pressure-bearing parts and supporting parts. However, pressure pipelines need to be tested after production before they can be used normally. In order to avoid damage to pressure pipelines during testing, a non-destructive testing instrument for pressure pipelines is required.
[0003] However, the prior art still has the following problems:
[0004] First of all, most of the existing non-destructive testing instruments for pressure pipes cannot automatically place the pressure pipes to be tested into water. Usually, the pressure pipes to be tested are held manually to prevent underwater testing. In winter, when the pressure is too high when held manually and placed in water for testing, the weather is cold and the water temperature is low, which may cause frostbite to the hands, reducing the practicality and safety of the tester.
[0005] Secondly, most of the existing non-destructive testing instruments for pressure pipelines are unable to clamp the pressure pipelines that need to be tested, and the testing is usually performed by holding the pressure pipelines. Manually holding the pressure pipelines is prone to shaking during testing, resulting in inaccurate testing of the pressure pipelines or damage to the pressure pipelines, thereby reducing the accuracy of the testing instrument in testing the pressure pipelines.
[0006] In view of the above problems, the inventor proposes a non-destructive testing instrument for pressure pipes to solve the above problems. Utility Model Content

The two ends of the two supporting plates are provided with a groove, and the ends of the two supporting plates are fixedly connected to the sliding blocks, and the sliding blocks are used in conjunction with the sliding blocks to prevent the connecting blocks from flipping over during lifting.
[0009] The two ends of the two-way screw rod are rotatably connected to one end of the opposite surface of the two connecting plates, and the two ends of the two-way screw rod are rotatably connected to one end of the opposite surface of the two connecting plates, so as to facilitate the rotation of the two-way screw rod.

When the device needs to place the pressure pipeline in water, When the water is pumped into the groove 4 opened on the operating table 1, a proper amount of water is first injected into the groove 4 opened on the operating table 1, and then the pressure pipe is placed in the detection component 3, and the first motor 27 is started.

Since a slot 34 is provided at the top of the bottom plate 33, the bottom ends of the two triangular plates 31 are fixedly connected with a block 38, and the slot 34 is used in conjunction with the block 38, so the triangular plates 31 will not flip over during the movement. Then, the two ends of the pressure pipe are aligned with the air nozzle 32 until the two triangular plates 31 have aligned the pressure pipe. Then, the lifting component 2 is started to lower the pressure pipe into the water in the groove 4. Subsequently, the air nozzle 32 injects air into the pressure pipe.
