Title: Valve for controlling the flow of hot fluids
IPC: F16K5/20
Filed: 1977-07-27
Abstract: A valve for controlling the flow of hot fluids in nuclear reactor plants or similar institutions has a tubular body whose internal surface is welded to an annulus of metallic leaf springs each connected to the outer end of a radially inwardly extending metallic spoke. The inner ends of the spokes are adjustably connected with a metallic sealing ring which is movable axially by a bellows into and from sealing engagement with a plate-like sealing member forming part of a plug-shaped or spherical valving element which is turnable or shiftable between open and closed positions. The bellows is caused to disengage the sealing ring from the sealing member prior to movement of the valving element to open or closed position and to engage the ring with the sealing member when the valving element assumes the open or closed position. That surface of the ring which is movable into sealing engagement with the sealing member has a channel which receives coolant by way of one or more ports in the sealing member and valving element. A stop is provided to limit the extent of movement of the ring in a direction away from the sealing member.
