Abstract

The invention relates to a method for detecting a leakage position of a sealed container. The method comprises the steps: filling a mixed gas into the sealed container, enabling the numerical value of a pressure gauge connected with the sealed container to reach a preset pressure value, and enabling the mixed gas to comprise hydrogen; closing a gas source, and maintaining the pressure of the sealed container; and detecting the hydrogen gas by using a hydrogen gas concentration detection device. According to the method, the problem that traditional leak detection equipment cannot perform accurate detection is fundamentally solved, and the detection cost is also reduced by adopting the hydrogen-containing mixed gas for detection.

Description

technical field [0001] The present application relates to the field of packaging, in particular to a method for accurately detecting the leakage position of a sealed container. Background technique [0002] In daily life and industrial production, sealed containers are widely used, such as various gas storage tanks, vacuum bottles, pressure tanks, etc. For a sealed container, airtightness is the most important function it must have. Therefore, after the sealed container is processed and manufactured, it is often necessary to conduct an airtight test to evaluate its sealing performance. [0003] figure 1 The method for detecting whether a sealed container is leaked that is currently commonly used is shown in . The usual method for testing the airtightness of the sealed container is to pass the detection gas inside the sealed container. After the sealed container is sealed and the pressure is maintained, the following processing methods can usually be used: 1) soak the seal...
