Abstract

The invention discloses a leakage detecting device of Hansen valve, comprising a ventilating tube whose first end is connected with a gas source; a detecting container which is limited with a detecting cavity that is gas-tightly connected with a second end of the ventilating end; multiple detecting pipes which are installed on the detecting container at intervals. One end of each detecting pipe is gas-tightly connected with the detecting cavity and the other end of each detecting pipe is gas-tightly connected with a Hansen valve. The leakage detecting device of Hansen valve provided by the embodiment of the invention has the advantage of high leakage detecting efficiency and greatly increases the production efficiency of the refrigerator.

Description

Technical field [0001] The invention relates to the field of household appliances, and in particular to a Hansen valve leak detection device. Background technique [0002] At present, in the production process of refrigerators, the Hansen valve is used to detect the vacuum degree of the refrigerator, which requires that the Hansen valve cannot leak (the leakage of the Hansen valve will cause the vacuum degree of the refrigerator to not meet the standard). Therefore, before the Hansen valve is used to detect the vacuum degree of the refrigerator, the Hansen valve needs to be leak tested, that is, whether the Hansen valve leaks. The existing Hansen valve leak detection device can only perform leak detection on one Hansen valve at a time, and a refrigerator production line needs to use hundreds of Hansen valves. Therefore, the existing Hansen valve leak detection device has the defect of low leak detection efficiency, which further greatly reduces the production efficiency of the r...
