Abstract
Abstract An internally insulated slide valve for throttling and blocking solids flow at high temperature and moderate pressure in fluid solids transfer lines. The metal body of the valve operates at lower temperatures than if it had no insulation. Internal parts of the valve are supported so that they do not transmit excessive heat through the supporting members to the body.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
242 words
A slide valve for use in high temperature fluid solids service comprising: a. a hollow body having inlet and outlet portions, b. an insulated bonnet normal to said body located between said inlet and outlet portions, c. a valve seat disposed within said body and adjacent said bonnet, d. means for supporting said valve seat from said body, e. a first sleeve comprising refractory material lining said inlet portion of said body for protection from erosion by fluid solids passing therethrough, f. first insulation means located between said first sleeve and said body for preventing exposure of said valve body to the temperature of the fluid solids flowing inside said first refractory sleeve, g. a second sleeve comprising refractory material lining said outlet portion of said body for protection from erosion by fluid solids passing therethrough, h. second insulation means located between said second sleeve and said body for preventing exposure of said valve body to the temperature of the fluid solids flowing inside said second refractory sleeve, i. a solid gate member mounted by sliding movement within said body and said bonnet normal to the direction of flow through said body whereby when said gate is operably disposed adjacent said valve seat, said gate member is adapted to block fluid solids flow through said body, j. guides for said solid gate member to position said gate member within said body, said guides being attached relative to said body by support means.
Claim 2
Dependent Claim

A slide valve for use in high temperature fluid solids service comprising: a. a hollow body having inlet and outlet portions, b. an insulated bonnet normal to said body located between said inlet and outlet portions, c. a valve seat disposed within said body and adjacent said bonnet, d. means for supporting said valve seat from said body, e. a first sleeve comprising refractory material lining said inlet portion of said body for protection from erosion by fluid solids passing therethrough, f. first insulation means located between said first sleeve and said body for preventing exposure of said valve body to the temperature of the fluid solids flowing inside said first refractory sleeve, g. a second sleeve comprising refractory material lining said outlet portion of said body for protection from erosion by fluid solids passing therethrough, h. second insulation means located between said second sleeve and said body for preventing exposure of said valve body to the temperature of the fluid solids flowing inside said second refractory sleeve, i. a solid gate member mounted by sliding movement within said body and said bonnet normal to the direction of flow through said body whereby when said gate is operably disposed adjacent said valve seat, said gate member is adapted to block fluid solids flow through said body, j. guides for said solid gate member to position said gate member within said body, said guides being attached relative to said body by support means.
Claim 3
Dependent Claim
27 words
The valve of clAim 1 wherein said means for supporting said valve seat is a frusto conical-shaped member attached to the inlet portion of the metallic body.
Claim 4
Dependent Claim
11 words
The valve of claim 1 wherein said valve seat is cylindrical.
Claim 5
Dependent Claim
38 words
The valve of claim 1 wherein said second refractory sleeve lining the outlet portion of the body is covered with a wear plate, said wear plate being supported relative to said body, thereby protecting refractory sleeve from erosion.
Claim 6
Dependent Claim
52 words
The valve of claim 3 wherein the external diameter of said valve seat is the same as the internal diameter of said first refractory sleeve whereby said valve seat support means is within said first sleeve of refractory material and said first insulation and is not exposed to erosion from fluid solids.
Claim 7
Dependent Claim
82 words
The valve of claim 3 wherein the external diameter of said valve seat is smaller than the internal diameter of said first refractory sleeve and said valve seat support means extends from said first refractory sleeve into the flow path through the valve and said first refractory sleeve is extended and conformed to the shape of said valve seat support means on the side facing the flow through the valve thereby protecting said support means from erosion by fluid solids flowing therethrough.
