Description

Hole part helium examines frock

Technical Field

The utility model relates to the technical field of helium detection, in particular to a hole part helium detection tool.

Background

Helium detection is a detection means, wherein helium with a certain pressure is filled into a detected workpiece after the detected workpiece is evacuated, and then the helium pressure change in the detected workpiece is detected by a helium mass spectrometer leak detector, so that whether the detected workpiece is qualified or not is judged.

When the hole parts are subjected to helium detection, helium needs to be filled into the holes and the holes are sealed, then the parts are connected into a helium mass spectrometer leak detector for detection, the existing sealing mode is to use a standard gasket to be arranged at the positions of the holes and further isolate the helium in the holes from leaking, however, the standard gasket is harder in material, the hole walls of the parts are easy to deform and be damaged by indentation after the standard gasket is used, the damaged hole parts are difficult to reuse, and scrapped treatment is required.
