| description | The utility model discloses a helium leakage detection teaching device. Comprising a vacuum pump, a vacuum container, a vacuum pipeline connected between the vacuum pump and the vacuum container, an instrument interface arranged on the vacuum pipeline and used for connecting a helium mass spectrometer, and a first interface arranged on the vacuum container and used for connecting a standard leak piece, the second interface is arranged on the vacuum container and is used for connecting a heat exchanger and/or a leak hole container; a plurality of vacuum leak holes which are respectively communicated with the inner space of the vacuum container and can be closed are formed in the side wall of the vacuum container. According to the helium leakage detection teaching device, the skill level of helium leakage detection operators is improved; the passing rate of the LT in personnel lossless leakage detection is improved; the method can be used for studying the relationship between gas leakage rate and molecular weig |
