Automatic detecting machine for air tightness of 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.

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
