Technical field

The utility model relates to the field of pressure pipeline detection, in particular to an airtight detection device for pressure pipelines.

Background technique

In a broad sense, pressure pipelines refer to all pipelines that are subject to internal or external pressure, regardless of the medium inside the pipe. A pressure pipeline is a part of a pipeline that is used to transport, distribute, mix, separate, discharge, measure, control and stop fluid flow. It consists of pipes, fittings, flanges, bolted connections, gaskets, valves, and other components. Or an assembly composed of pressure parts and supports.

At present, when the pressure pipeline is in use, its air tightness needs to be tested. The two ends of the pipeline are plugged with pipe plugs to make the pipeline in a sealed state. Then the pressure pipe is inflated and tested with a pressure gauge.
