According to news from the financial industry on May 31, 2024, according to an announcement from the State Intellectual Property Office, Suzhou Coma Materials Technology Co., Ltd. has obtained a project called "a detection device for helium leakage in ceramic tubes", with the authorization announcement number CN221055987U. The application date is September 2023.
The patent abstract shows that the utility model discloses a device for detecting helium leakage in ceramic tubes, which includes a detection body formed with a through hole, and two annular placement grooves are provided on the side wall of the through hole. A sealing ring is installed in the placement groove; the diameter of the through hole is larger than the diameter of the ceramic tube; a vent hole is provided on the side wall of the through hole between the two placement grooves, and the vent hole is connected to the helium mass spectrometer The detector is connected. By arranging the detection body and the through hole on the detection body, when detecting the ceramic tube, the ceramic tube is extended into the through hole, and the two sealing rings realize the sealing of one section of the ceramic tube, so The helium mass spectrometer detects the vacuum of the space between the two sealing rings, sprays helium gas outside the two sealing rings, and uses the helium mass spectrometer to detect the sealing effect of this section of the ceramic tube and realize the surface roughness of the ceramic tube. judgment.
