ABSTRACT:
A guided slide valve having wear-prone internals which can be removed through the bonnet opening and which can operate in high pressure, high temperature erosive solid or fluid flow systems is disclosed which includes a body having a flow passage through it, a large internal portion closed by a removable bonnet or cover, a body portion projecting into the enlarged internal portion, preferably a cone suspended in non-external load-bearing relation with the body, the projecting portion having sides spaced from internal walls of the enlarged internal portion, a valve surface or orifice disposed on the projected body portion, preferably releasably secured, and a slide valve slideable in the enlarged internal portion adjacent the valve surface having transversely spaced side members which extend around the sides of the projecting body portion. Interfitting guides and slides are disposed on the sides of the projecting portion and on the side members of the slide valve for guiding of the slide valve to open and closed positions, and accordingly, they are disposed 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 of a material different from the valve body and is supported on a body ledge with a bi-metallic weld between the cone and the body that is not subject to external loads. Preferably, the body has an external shell constructed of low cost, low temperature materials and include insulation material which reduces heat flow and 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.
