ABSTRACT:
A disc valve for placement in a cylindrical housing forming part of a conduit which has a pivotally mounted disc and a valve seat that is angularly inclined relative to a plane perpendicular to an axis through the housing. The disc has a peripheral seal defined by a plurality of seal rings disposed within a peripherally open groove in the disc. The root diameter of the groove is smaller than the inner diameter of the seal rings so that the latter can float relative to the former. A lock ring securely retains the seal rings in place after the seal rings have been centered relative to the valve seat by first closing the disc and thereafter tightening the lock ring. A space between the seal rings includes generally radially oriented openings in fluid communication with a source of a pressurized medium on the exterior of the valve for applying the medium to the space between the seal rings and to thereby clean the valve seat when closing the disc. When the disc is closed the medium forms a pressure barrier between the upstream and the downstream sides of the disc.
