Abstract

진공밸브의 제조에 있어서, 제조코스트 및 공기를 단축하지 못해 현재까지 신뢰성이 저하했었다. 접합부를 단판(15)과, 한편 잡기실드(20)의 일단측을 외부로 구부려서 형성된 단판(15)보다 작은 직경을 갖는 외측 절곡단(20a)과 이 외측절곡단(20a)보다 작은 직경을 갖고 일단이 절연용기에 접합된 봉착부재(21)의 타단측을 내측으로 절곡해서 형성된 내측절곡단(21a)이 순차로 적층되는 동시에 단판(15), 외측절곡단(20a) 및 내측절곡단(21a)은 각 적층면간에 배치되는 납재의 용융에 의해 접합되도록 구성된다.In the manufacture of vacuum valves, the manufacturing cost and air cannot be shortened, and reliability has been deteriorated to date. It has an outer bent end 20a having a smaller diameter than the end plate 15 and the end plate 15 formed by bending one end side of the holding shield 20 to the outside and a diameter smaller than the outer bent end 20a. The inner bent end 21a formed by bending the other end side of the sealing member 21, one end of which is joined to the insulating container, is sequentially stacked, and at the same time, the end plate 15, the outer bent end 20a, and the inner bent end 21a. ) Is configured to be joined by melting of a brazing filler material disposed between each laminated surface.
