Description

Technical Field

[0001] The utility model relates to the technical field of airtight detectors, in particular to an air path structure of an airtight detector which is leak-proof. Background Art

[0002] The air tightness tester uses the latest foreign microcomputer chips, high-precision sensors and zero-leakage solenoid valves to ensure the accuracy of the test results and the durability of the instrument. The microcomputer automatically controls the test process and collects data, and uses the latest algorithms and special software to analyze and process the data, compensating for the influence of temperature and other factors during the test process to the greatest extent. The traditional test of the sealing of the test piece is to use the water or oil immersion visual bubble method. Its equipment is simple and the results are intuitive, but the detection accuracy and efficiency are low, and the human factor has a greater impact. It cannot achieve automatic quantitative leakage detection. At the same time, it will also cause moisture and rust to the workpiece, impurity immersion and other adverse effects, and cumbersome surface water treatment of the test piece. Some products are not even allowed to be tested by this method.

[0003] When the existing airtightness detector is in use, the gas path structure is connected to the external object to be detected, and the connection mechanism has no buffering effect. During use, the connection parts need to be repeatedly plugged in and out, which can easily lead to a decrease in the sealing of the connection parts, causing gas leakage, reducing the use effect of the gas path structure, and failing to meet the use requirements.
