Abstract
The invention concerns a water-cooled casing for a hot-blast slide valve, in particular a slide valve in a pipe lined with refractory material. The casing has annular cooling-water ducts disposed concentrically with respect to each other in pairs, one downstream of the other with respect to the hot-air blast and on both sides of the space through which the sliding plate of the valve passes. The annular ducts are formed by two monobloc-construction casing components, each of which has two substantially annular hollows, the hollows being closed over by first and second annular components to form the ducts.
Claims16
A water-cooled housing for hot-blast slide valves having annular coolant channels arranged at both sides of a guide space for a valve plate lying following one another in a flow direction of a hot-blast and that are seated concentrically inside one another in pairs, comprising said annular channels being formed by two one-piece housing parts, each of which comprises two essentially annular depressions, said depressions being connectable by first and second annular parts for the formation of the annular channels.
A water-cooled housing for a hot-blast slide valve comprising:
- two pairs of annular coolant channels, said two pairs arranged following one another in a flow direction of a hot blast at both sides of a fluid space for a valve plate;
- said channels of each pair being seated concentrically inside one another;
- each of said pairs of channels being formed in a one-piece housing part having two annular depressions;
- a first annular part for overlying a first of said depressions to form a first channel;
- and
- a second annular part for overlying a second of said depressions to form a second channel.
