适用于两种垫圈的超导腔铌钛法兰装置
摘要：
本发明属于加速器的超导加速腔体领域。一种适用于两种垫圈的超导腔铌钛法兰装置，包括有上法兰和铌腔体上的铌管件连接的下法兰，其主要特点在于：在上法兰的密封面上设有直角缺口，在下法兰的密封面上设有凸台，直角缺口与下法兰密封面及凸台侧面形成的腔为密封腔，其内设有密封圈。本发明的优点是既可以使用镁铝合金垫圈也可以使用铟丝垫圈。既能保证腔体的真空密封，又减少铟丝密封法兰的使用数量，节省安装和拆除垫圈的人力、时间，同时还有效的避免铟丝污染腔体。
摘要（英）：

The invention belongs to the field of a superconducting acceleration cavity of an accelerator, and provides a niobium and titanium flange device with a superconducting cavity suitable for two types of washers. The device comprises an upper flange and a lower flange, wherein the lower flange is connected with a niobium pipe of a niobium cavity. The device is characterized in that the sealing surface of the upper flange is provided with a right-angled notch, the sealing surface of the lower flange is provided with a boss, a cavity which is formed by the right-angled notch, the sealing surface of the lower flange and the side surface of the boss is a sealing cavity, and the interior of the cavity is provided with a sealing ring. The device has the advantages that the device is suitable for both of the magnalium alloy washer and the indium washer; the vacuum sealing of the cavity is ensured, the usage amount of indium sealing flanges is reduced, the labor and time of installing and detaching the washers are saved, and meanwhile, the pollution to the cavity by the indium is effectively avoided.
