A pipeline exhaust detection method

Abstract

The invention belongs to the pipeline detection technology, and in particular relates to a method for detecting whether the exhaust gas in the channel of a complex casing is unobstructed. In the pipeline exhaust detection method of the present invention, a detection channel connected with the channel to be tested is set, and the channel to be tested and the detection channel are both connected to the air inlet, the remaining exhaust ports are excluded, and a flow meter is connected to the detection channel. If the gas flow rate is measured, the exhaust of the channel to be tested is not smooth; otherwise, the channel to be tested is exhausted smoothly. The method of the present invention can conveniently and accurately judge the unobstructed exhaust condition of complex channels inside the product, effectively screen out unqualified products, improve the pass rate of product inspection, and greatly reduce subsequent losses caused by assembling unqualified products. The test proves that it can 100% check out unqualified shells, and has great practical application value.

Description

technical field [0001] The invention belongs to the pipeline detection technology, and in particular relates to a method for detecting whether the exhaust gas in the channel of a complex casing is unobstructed. Background technique [0002] At present, a certain type of regulator has a large number of products leaking air, and it is found that the reason is that the exhaust of the shell is not smooth. After analysis, due to the complex structure of the product, the large number of internal pipes, and the difficulty in processing, there are a large number of defects such as cross holes, burrs, gaps, and dislocations in the internal pipes of the product. It is easy to be blocked, so that the air flow inside the product cannot be discharged smoothly, resulting in various hidden dangers. [0003] The existing technology lacks an effective detection and troubleshooting method for exhaust blockages with complex pipelines inside, which greatly affects the qualified rate of product...
