この発明の真空バルブによれば、ゲッターの脱落物を、端部金具と端板との間の空間部に閉じ込めることができるため、ゲッターの脱落物が高電界部まで拡散することはなく、耐電圧性能を安定、向上することができる。
また、ゲッターは、空間部に閉じ込められるので、端部金具に固着させる必要はなく、ゲッター両面のガス吸着機能を活用できるため、真空度の信頼性を向上させることができる。また、ゲッターは、スポット溶接やロウ付けなどの取り付け作業をすることなく空間部内に封入することができるため、真空バルブの組立作業性を良くすることができる。
According to the vacuum valve of the present invention, since the getter fallout can be confined in the space between the end fitting and the end plate, the getter fallout does not diffuse to the high electric field portion and is resistant to damage. Voltage performance can be stabilized and improved.
Further, since the getter is confined in the space portion, it is not necessary to fix the getter to the end fitting, and the gas adsorption function on both sides of the getter can be utilized, so that the reliability of the degree of vacuum can be improved. In addition, since the getter can be enclosed in the space without performing attachment work such as spot welding or brazing, the assembly workability of the vacuum valve can be improved.

また、このゲッター16は、固定側端部金具15内に配置して、その後、円板状の固定側端板2の外端部と固定側端部金具15の連結部をロウ付けすることで空間部17に配置される。このゲッター16は、例えばスポット溶接やロウ付けなどによって、固定側端部金具15に固着する必要はない。ゲッター16は、ボタンタイプ、板状タイプどちらでも適用でき、かつ複数個配置してもよい。この端部構造は、固定側のみならず、可動側に適用しても、固定側と固定側の両側に適用してもよい。ゲッター16は、固定側の空間部にのみ、可動側の空間部にのみ、固定側と可動側の両方の空間部に配置してもよい。 Further, the getter 16 is disposed in the fixed side end fitting 15, and then the outer end portion of the disk-shaped fixed side end plate 2 and the connection portion of the fixed side end fitting 15 are brazed. Arranged in the space 17. The getter 16 need not be fixed to the fixed-side end fitting 15 by spot welding or brazing, for example. The getter 16 can be either a button type or a plate type, and a plurality of getters 16 may be arranged. This end structure may be applied not only to the fixed side but also to the movable side, or to both sides of the fixed side and the fixed side. The getter 16 may be arranged only in the space portion on the fixed side, only in the space portion on the movable side, and in both space portions on the fixed side and the movable side.
