Abstract: A seal arrangement is installed between confronting co-planar portions of a low pressure steam turbine exhaust hood and a circular bulkhead that forms part of an exhaust duct structure of a steam turbine module. The seal arrangement forms a vacuum seal between the interior and exterior of the exhaust hood and comprises a flexible gasket in the form of an annular diaphragm. This diaphragm has a radially inner circumferential portion that seals with the bulkhead, a radially outer circumferential portion that seals with the exhaust hood, and a radially median resilient portion. Sealing is achieved by providing radially inner and outer clamping flanges operative to sealingly clamp inner and outer circumferential portions of the gasket to the bulkhead and the exhaust hood respectively. To enable quick access to the interior of the exhaust hood, the clamping flanges comprise upper and lower halves and the upper part of the gasket is sealed to the upper parts of the exhaust hood and the bulkhead by an arrangement of flanges and counter-flanges, the counter-flanges being releasably secured to outside surfaces of the exhaust hood and the bulkhead.
Abstract translation: 密封装置安装在低压汽轮机排气罩的相对的共平面部分和形成汽轮机模块的排气管道结构的一部分的圆形舱壁之间。 密封装置在排气罩的内部和外部之间形成真空密封，并且包括呈环形隔膜形式的柔性垫圈。 该隔膜具有与隔板密封的径向内周部分，与排气罩密封的径向外周部分和径向中间弹性部分。 密封是通过提供径向的内部和外部夹紧凸缘来实现的，所述凸缘可操作用于将垫圈的内部和外部周向部分密封地夹紧到隔板和排气罩。 为了能够快速进入排气罩的内部，夹紧凸缘包括上半部和下半部，并且垫圈的上部通过凸缘和相对凸缘的布置被密封到排气罩和隔板的上部， 该反向凸缘可释放地固定在排气罩和隔板的外表面上。

Abstract: The present invention relates to a device for inserting a balancing weight into a rotor of a turbine, that includes an external component and an internal component. The internal component is connected in a helical manner to the external component. The internal component delimits a chamber which has a first and a second opening, a lower surface which is provided with a sealing joint and a cap in order to close in a tight manner the first opening of the chamber. The connection between the external component and the internal component is helical, that is to say, the result of a threading operation. Therefore, the internal component can thus move in a coaxial manner with respect to the external component.
