Abstract

A valve plate for a gate valve for controlling the flow of molten metal is formed from two or more identical ceramic plate sections (25) having mating semi circular recesses (26) to enclose and lock in position one or more tubular ceramic nozzles (45,48). The plate sections and nozzles are held together and supported by a metal case (41) which in the bottom valve plate shown in Fig. 7 has depending, metallic tubular casing sections (50) to encase the lower portions of nozzles (45,48) and lower nozzle extensions (52,54) which are releasably mounted by bayonet fittings in the casing sections (50). <IMAGE>

Description

Inventive refers to metallurgy.

The purpose of the invention is improving the reliability of the operation of the slide gate elements,

FIG. 1 shows a sliding gate front view; fig 2 is the same, bottom view; . in fig. 3 section aa in FIG. in Fig 4 ° the section in Fig 2; in g, 5 - section bb in fig. 35 in fig. 6 diagram of the assembly of the upper shshty; FIGS. 7-9, variants,

The sliding slide valve comprises a housing 1, located under the casting lid 2 and connected to its bottom 3 by means of connecting elements 4. In the housing 1 there are located upper 5 and lower 6 plates, each of which is made of parts. and enclosed in a metal casing 7 and 8, respectively. Into the openings of the upper plate of the plate 5, inserts 9 and 10 are installed, with annular grooves G, the Upper plate 5 consists of parts 12 and 13 whose plane of the connector passes through the openings 5 in which the inserts 9 and 10 are installed, , The holes have retaining flanges 14 for butt with grooves 11, Holes of the plate 6 are installed into the holes. Filling nozzles of $ 15 are installed. They are fixed similarly to the fastening of the inserts 9 and 10 of the upper plate 5, Holes 15 can have removable extensions 16; connecting bayonet with clip.
