Abstract

The invention provides a pipeline tightness detection device and a pipeline tightness detection method, wherein the pipeline tightness detection device comprises: an installation seat; The measuring end of the mounting seat, the air bag is provided with an inflation port, and the measuring end is used to extend into the pipeline to be measured; the hydraulic injection structure is arranged on the opposite ends of the air bag in the length direction, and It is sealingly connected with the airbag, the hydraulic injection structure has an input end and an output end, the output end is arranged close to the measurement end, and is used for filling fluid into the pipeline to be measured; and a pressure detector is arranged on the On the hydraulic injection structure, it is used to detect the fluid pressure in the hydraulic injection structure. The pipeline tightness detection device and the pipeline tightness detection method provided by the invention not only improve the work efficiency of the tightness test, but also reduce the workload of the tightness test.

Description

technical field [0001] The invention relates to the technical field of pipeline tightness detection equipment, in particular to a pipeline tightness detection device and a pipeline tightness detection method. Background technique [0002] At various stages of valve installation, testing and repair, it is often necessary to carry out a tightness test. The current tightness test generally adopts blind flange or buckle tank type for pressure. The flange is assembled or welded with the inlet pipe of the valve under test with a pressure test tank, and then the pressure test is carried out by adding water pressure through the water pressure injection port. However, the use of blind flange pressure test type for sealing test requires installation and removal of blind flanges; the use of buckle tank pressure test type for sealing test requires a lot of pre-processing and post-processing work. Before the test, seal the pressure test tank and pipe After the test is completed, the sea...
