[0002] A pipeline is a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Usually, the fluid flows from the high pressure part of the pipeline to the low pressure part after being pressurized by blowers, compressors, pumps and boilers. It can also be conveyed by the fluid's own pressure or gravity. Pipelines are widely used, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices.

[0003] In order to ensure that the pipeline can be used normally in the corresponding device, the pipeline needs to be tested for air tightness before use, such as the air tightness detection mechanism of a pipe fitting disclosed in patent application No. 202221708524.2, including a differential pressure transmitter, which has a first detection pipeline and a second detection pipeline that are independently arranged; a differential pressure sensor, which is located between the first detection pipeline and the second detection pipeline; a first opening and closing ball valve, which is connected to one end of the first detection pipeline, and the other end of the first detection pipeline is connected to a material placing tool, and a pressure plug for sealing the pipe connector is provided above the material placing tool: a second opening and closing ball valve, which is connected to one end of the second detection pipeline, and the other end of the second detection pipeline is connected to a pressure sensor: the first opening and closing ball valve and the second opening and closing ball valve are also externally connected to fluid pipelines, respectively.

[0004] Although the above technical solution can perform airtightness detection on pipelines, its structure is relatively complex. On this basis, and in order to meet the diversified development of the market, an inclined and adjustable pipeline airtightness detection tooling is proposed. Utility Model Content

[0029] The pipeline is placed between two groups of support plates 1 5 and 2 6, with one end of the pipeline against the middle of the second pressure plate 13. The cylinder 7 pushes the pressure plate 8 to move the pressure plate 1 9 toward the second pressure plate 13. The pipeline is clamped between the pressure plates 1 9 and 13. At this time, the inflation hole 11 is inflated and transported to the pipeline through the inflation head 10. At this time, the second support plate 6 is pressed down and tilted, and the inflated pipeline is immersed in water.
