Alumina ceramic and metal sealing welding piece with coaxial structure
The invention discloses an aluminum oxide ceramic and metal sealing welding piece with a coaxial structure, which is characterized by comprising a stainless steel flange, ceramic, an oxygen-free copper inner conductor, an oxygen-free copper sleeve, a molybdenum ring, an oxygen-free copper welding ring and a molybdenum welding ring which are coaxially assembled, the stainless steel flange is fixedly welded with the end part of the oxygen-free copper sleeve; the ceramic is assembled in the oxygen-free copper sleeve, and the outer circle face of the ceramic boss is welded to the inner wall of the oxygen-free copper sleeve in a sleeved and sealed mode. The molybdenum ring is assembled on the outer lower side of the oxygen-free copper sleeve; through holes matched with the oxygen-free copper inner conductor are formed in the centers of the ceramic, the oxygen-free copper welding ring and the molybdenum welding ring; the lower end of the oxygen-free copper inner conductor is sequentially inserted into the through holes of the ceramic, the oxygen-free copper welding ring and the molybdenum welding ring and is welded with the inner surface of the hole in the lower end part of the ceramic and the inner surfaces of the through holes of the oxygen-free copper welding ring and the molybdenum welding ring; and the oxygen-free copper welding ring is welded with the lower end part of the ceramic and the upper end part of the molybdenum welding ring. The welding part can bear high-voltage impact while meeting the high-vacuum sealing requirement.
本发明公开了一种同轴结构的氧化铝陶瓷与金属密封焊接件，其特征在于，包括同轴装配的不锈钢法兰、陶瓷、无氧铜内导体、无氧铜铜套、钼环、无氧铜焊接圈和钼焊接圈；不锈钢法兰与无氧铜铜套端部焊接固定；陶瓷装配在无氧铜铜套内部，并且陶瓷凸台外圆面与无氧铜铜套内壁套封焊接；钼环装配在无氧铜铜套外下侧；陶瓷、无氧铜焊接圈和钼焊接圈的中心均设有与无氧铜内导体匹配的通孔，无氧铜内导体的下端依次插入陶瓷、无氧铜焊接圈和钼焊接圈的通孔并与陶瓷下端部孔内表面、无氧铜焊接圈和钼焊接圈的通孔内表面焊接；无氧铜焊接圈与陶瓷下端部、钼焊接圈上端部焊接。本发明的焊接件在满足高真空密封要求的同时能够承受高电压冲击。
