Method for congregating air bubble in liquid

Abstract

The invention provides an aggregation method of bubbles in liquid. The method comprises the processes that: a bubble collecting device is covered above a bubble source (components under detection) within the liquid, so that the bubbles generated in the bubble source can be aggregated by and by in the process of ascending in the liquid. Thus, the bubbles generated in a bigger scale are aggregated into a relatively smaller scale, enabling the bubbles to be observed and detected conveniently. The method of the invention can reduce the bubble observing or testing range to an appropriate or favorable scale which is beneficial to the observing or the testing, therefore the minute bubbles which is impossible or difficult to be observed or detected can be observed and detected without restriction of the physical dimension of the object under test. Being mainly for the aggregation and detection of bubbles, the method and the device can be used for tightness test of pipelines, containers or some other components which are required to be sealed. The method is simple, easy, and applicable to diversified statuses and occasions.

Description

Technical field: [0001] The invention relates to a method for gathering air bubbles in a liquid, which is mainly applied to the gathering and detection of air bubbles in a liquid. Background technique: [0002] In the prior art, when there are tiny gas leakage points in the pipelines, containers or other components with a certain internal gas pressure, the traditional method is to put these leaking components in the liquid and directly observe whether they are leaking or not. Bubbles are generated to determine whether a leak has occurred. But above-mentioned method can be subject to the restriction of two aspects factor, one is limited by the geometrical size of detected object, if the geometrical size of detected object is very large, the range of the liquid that needs to be observed will also be very large; When it is very small, it is impossible or not conducive to observation and detection. Invention content: [0003] Aiming at the shortcomings of the above-mentioned...
