ABSTRACT:
A slide valve with integrated removable internals which can operate with fully reversing pressures in a high pressure, high temperature, erosive solid or fluid flow system is disclosed which includes a body having a flow passage through it including a large internal portion, a body portion projecting into the enlarged internal portion, preferably a cone suspended in non-external load bearing relation with the body, a valve surface or orifice plate releasably secured on the projecting body portion, and a slide valve slideable in the enlarged internal portion adjacent the valve surface having side portions extending transversely of the direct flow passage in the enlarged internal portion. Traversely spaced guides are disposed in the enlarged internal portion, either releasably secured to the valve surface or formed integrally with the valve surface which are in the form of side members. The transversely extending portion of the slide valve has slides that interfit with the guides so that the slide valve is guided adjacent the valve surface into open and close position and out of the direct flow path through the flow passage. The valve may have a single slide valve or a double slide valve arranged in end-to-end relationship for opening and closing the valve. Preferably the support cone is made up of material different from the valve body and is supported on a body ledge with a bi-metallic weld between the column and the body that is not subject to external load. Preferably, the body has an external shell constructed of low cost, low temperature materials, includes insulation material which reduces heat flow and includes an erosion-resistant surface or lining. Advantageously, a removable bearing sleeve with a removable insulation assembly are included in the valve. Other features are disclosed.
