Abstract

The invention provides a pipeline air-tightness detection device and a pipeline air-tightness detection method. The pipeline air-tightness detection device comprises a mounting base; an air bag which is provided with a connecting end arranged in the mounting base and a measuring end protruding out of the mounting base and used for stretching into a pipeline to be measured, and is provided with an inflation inlet; a hydraulic injection structure which is arranged at the two opposite ends, in the length direction, of the air bag in a penetrating mode and connected with the air bag in a sealing mode, and is provided with an input end and an output end which is arranged close to the measuring end and used for filling the pipeline to be measured with fluid; and a pressure detector which is arranged on the hydraulic injection structure and is used for detecting the pressure of fluid in the hydraulic injection structure. According to the pipeline air-tightness detection device and the pipeline air-tightness detection method provided by the invention, the air-tightness test working efficiency is improved, and the air-tightness test workload is also reduced.

Description

technical field [0001] The invention relates to the technical field of pipeline airtightness detection equipment, in particular to a pipeline airtightness detection device and a pipeline airtightness detection method. Background technique [0002] In the various stages of valve installation, testing and repair, it is often necessary to conduct a sealing test. The current sealing test generally uses a blind flange or buckle tank type for pressure, and the blind flange with a water pressure inlet and the inlet pipe of the tested valve are used Assemble the flange or use a pressure test tank to butt-weld the inlet pipe of the valve under test, and then add water pressure through the water pressure injection port for pressure test. However, it is necessary to install and disassemble the blind flange when using the blind flange pressure test type to conduct the airtightness test; to conduct the airtightness test by using the buckle tank pressure test type requires a lot of pre-pr...
