Description

Technical Field

[0001] The utility model relates to the field of liquid storage tank detection, in particular to a helium detection tool. Background Art

[0002] Liquid storage tanks are typically used on high-pressure pipelines, installed between the condenser outlet and the evaporator. Their primary functions are liquid storage, filtration, and drying. Vehicle heat pump air conditioning systems require more refrigerant to accommodate the different cooling and heating modes, necessitating a corresponding liquid storage tank. After manufacture, liquid storage tanks often need to be tested for leaks. Helium testing is a common method for this. The workpiece under test is evacuated and then filled with helium at a certain pressure. A vacuum chamber with a certain vacuum requirement is placed outside the workpiece, which is connected to the leak detection port of a helium mass spectrometer. If the workpiece under test has a leak, the helium leaking into the vacuum chamber can be detected by the helium mass spectrometer.

[0003] Currently, helium inspection of liquid storage tanks requires manual connection of the liquid storage tank to the helium pipeline. On the one hand, this is time-consuming and labor-intensive. On the other hand, manual connection cannot ensure that the liquid storage tank and the helium pipeline are tightly connected. A loose connection will cause helium leakage and thus judge the liquid storage tank with good sealing as defective, which will cause waste and increase costs. Utility Model Content
