Abstract
A closure and seal construction for a high-pressure oxidation furnace and the like having a quartz chamber and an integral quartz wall formed with an opening for receiving into the chamber material to be processed, the wall providing an annular surface surrounding the opening and being formed with an annular recess in the surface surrounding the opening; a combined cooling and sealing tube mounted in the recess and protruding slightly therefrom; a closure mounted for engagement with the tube and wall surface; and the tube having an elasticity responsive to a closing pressure to resiliently retract and provide simultaneous sealing engagement of the closure with the wall surface and tube.
Claims3
A closure and seal construction for a high pressure oxidation furnace and the like having a quartz chamber and integral quartz wall formed with an opening for receiving into said chamber of material to be processed, said wall being formed with an annular recess surrounding said opening;
- a tube mounted in said recess and comprising an interior metallic wall providing thermal conductivity and an elastomeric coating providing elasticity and dimensioned for protrusion of said coating from said recess and being adapted for connection to a source of coolant and for conduction of said coolant therethrough;
- a closure and mounting means therefor juxtaposing said closure and wall and tube in covering relation to said opening and applying a closing pressure urging said closure toward said wall and tube, said closure having a flat annular surface confronting said wall and engageable with and compressing said coating;
- and
- said coating being responsive to said clsoing pressure to seal said opening.
