Problems solved by technology

However, at present, the airtightness of the pipeline is mainly tested by filling the pipeline with high-pressure gas and immersing the pipeline in water or foaming agent. This inspection method is not rigorous, and it is easy to miss micropores.
Moreover, after the inspection, the inner hole of the pipeline must be cleaned and dried, which increases the time and difficulty of the next process.
As a result, the work efficiency of pipeline product production is low
[0003] Or use the method of measuring the pressure difference of high-pressure gas in the pipe

Abstract

The invention discloses an automatic detecting machine for the air tightness of a pipe. Two ends of the pipe are compressed and sealed, and high-pressure air-charging is performed on the pipe; and a pipe air tightness detecting system starts to detect air leakage of the pipe, and in an air leakage detecting process, if microporous air leakage is detected, an air leakage detecting ring transmits a signal and an alarm device sends an alarm immediately.

Description

【Technical field】 [0001] The invention relates to a pipeline airtightness testing machine, in particular to an automatic pipeline airtightness testing machine device. 【Background technique】 [0002] The pipeline air tightness testing machine is mainly used to detect whether there are micropores in the pipeline wall to cause air leakage. Since pipelines are usually used to transport various gases (including toxic and polluted gases) or various liquids (including toxic and polluted liquids), the airtightness detection of the pipeline wall is very important. Therefore, the pipeline air tightness testing machine has a wide range of uses. However, at present, the airtightness of the pipeline is mainly tested by filling the pipeline with high-pressure gas and immersing the pipeline in water or foaming agent. Moreover, after the detection, the inner hole of the pipeline must be cleaned and dried, which increases the time and difficulty of the next process. Therefore, the work ef...
