Abstract
A slide valve for use in applications where gated fluid temperatures may exceed approximately 1600.degree. F. and exterior valve wall temperatures may be less than approxiamtely 600.degree. F. connects the valve bed plate to the valve body by use of a ring of conical cross section which is resiliently flexible in a response to thermal expansion or contraction of the ring so as to maintain the valve bed plate in a fixed relationship with respect to the valve body over a preselected temperature range. In one preferred embodiment of the invention, the valve orifice is propped against the valve bed plate by supports mounted on gussets that have grooves alternately spaced in their opposite faces so as to provide a heat sink between the orifice and the valve body. In another preferred embodiment intended for use in applications where the gated fluid temperature ranges from approximately 1000.degree. F. or less to an exterior valve body temperature of 600.degree. F. or less, the bed plate is connected to the valve body by an annular ring having concentric grooves alternatively spaced in opposite faces of the ring to define a heat sink between the bed plate and the body. The bed plate and the annular ring may be of a unitary construction.
