| titleOfInvention | Stainless steel source shell structure of Kr-85 gas sealed radiation source |
| abstract | The utility model relates to a Kr-85 gas seal radiation source stainless steel source shell structure, including the casing, install the source window in casing one side, the top pressure equipment technology backing ring of source window, the inside of casing has the gas storage chamber, is equipped with the inflation inlet with gas storage chamber intercommunication on the casing, and inflation inlet department connects the gas tube, and the outside of inflation inlet is equipped with the source lid. The source shell structure adopts the brazing technology to weld the gas-filled tube and the shell body, so that the sealing performance of the gas-filled pipeline is ensured, the welding flux adopts low-temperature brazing solder, compared with the originally adopted silver welding, the welding temperature is obviously reduced, and the oxidation of the source shell material under the high-temperature condition and the change of the mechanical property of the material are prevented; the source cover adopts a structural design with smaller size, avoids adopting a plasma welding mode, simplifies the welding process and improves the working efficiency; the source cover and the source window are uniformly welded by laser, the laser welding heat input is less, the welding seam is smooth, the local welding is realized, the oxidation risk of the whole source shell in the welding process can be obviously reduced, and the appearance of the source shell is improved. |
