ABSTRACT:
This is a new slide valve arrangement. It includes a housing having a longitudinal axis and a disc valve or gate movable by an external hydraulic or mechanical actuator. The gate slides along a first surface of a guide member. There is a throat member through which the material to be regulated is directed. The throat supports a fixed wedge which is thin on the exterior and has a greater thickness on the interior. A movable wedge having an inclined surface mating with the incline surface of the fixed wedge is provided. Means are provided to position the movable wedge between the guide member and the inclined surface of the fixed wedge such that as the temperature of the valve increases, the movable wedge is forced tighter and tighter between the fixed wedge and the guide member. This give additional compressive strength to the valve.
