| titleOfInvention | Vacuum sealing device for bubble mouth for storing hydrogen atom frequency standard |
| abstract | The application discloses bubble mouth vacuum seal device is stored to hydrogen atom frequency standard, bubble mouth vacuum seal device is stored to hydrogen atom frequency standard establishes the copper nut outside vertical tubulose storage bubble mouth upper portion including the cover, store and be provided with vertical tubulose glue film between bubble mouth and the copper nut, set gradually below the copper nut and establish the annular wave form bullet pad, first titanium ring, polytetrafluoroethylene ring, second titanium ring and indium wire circle outside storing the bubble mouth, the lower extreme of storing the bubble mouth is provided with annular polytetrafluoroethylene cap, outside the copper nut lower part, and wave form bullet pad, first titanium ring, polytetrafluoroethylene ring, second titanium ring, indium wire circle and polytetrafluoroethylene cap all overlap and are equipped with vertical tubulose titanium connector outward; the device can avoid the micro leakage of the hydrogen atom frequency standard at the vacuum sealing position of the bubble opening in the assembling, debugging and even later-stage use process, and improve the sealing reliability so as to ensure that the hydrogen atom frequency standard can reliably operate for a long time. |
