1951 F. H. JOHNSON HIGH-TEMPERATURE GAS VALVE Filed Jan. 20, 1948 Fred H Ja/zrzsorz Patented Nov, 20, 1951 UNITED STATES PATENT OFFICE United States Steel Com New Jersey I pony, a corporation of Application January 20, ms, Serial No. 3.329
8 Claims. (01. 251-159) This invention relates to valves for controlling flow of high temperature gases and particularly to water cooled closure disks embodied in such valves.
An object of the invention is to provide gas valve closure disks having improved and highly efficient means for circulating cooling water therethrough. V
A further object of the invention is to provide improved gas valve closure disks of metal construction in which the exposed faces are insulated with refractory material for protection against high temperatures.
A further object of the invention is to provide improved valve closure disks of simplified construction having continuously water cooled sealing means for engagement with valve seats.
In accomplishing these and other objects of the present invention, I have provided improved details of structure. a preferred form of which is shown in the accompanying drawing, wherein:
Figure l is a vertical sectional view through a gas valve having a closure disk embodying features of the present invention.
Figure 2 is an enlarged vertical sectional view of a portion of the closure disk shown in Figure 1.
Figure 3 is a top plan view with parts cut away, illustrating a portion of the improved closure disk.
Referring more in detail to the drawing:
In Figure 1 there is shown at It a portion of a valve body adapted to control flow of hot gases, as for example the hot air blast to a metallurgical blast furnace. The body contains an annular seat [2. Said seat and body may be of any conventional design and hence are not shown nor described in greater detail.
A closure disk l3, constructed in accordance with the present invention, is cooperable with the upper face of seat I! to close the valve against fiow of gases. Disk I 3 is fixed to the lower end of a stem ll which may be raised and lowered by any suitable external operating mechanism, not shown.
As best shown in Figure 2, disk I3 comprises a hollow annular; pipe l l which extends around the circumferenceiof-the disk and is tangentially engag'eable iwithuseat -li to seal the valve. Said pipe has a'circum erential opening in its upper region, opposite siting region. A lower dome shaped plate Ilisjoinedto the inner circumferential edge of theiope'ning in the pipe, and an upper cone shaped plate I1 is joined to the outer circumferential edge. The lower end of stem I4 is Joined to upper plate I'I. Stem I4 is tubular and carries a concentric water inlet tube It which terminates slightly above plate It. A central dome shaped baiile I9 is fixed to the lower end of tube II and at its circumference carries a circular flange III which extends downwardly within pip'eglfi through the circumferential opening is defines water inlet and discharge orifices.
Figure 3, a plurality of radial vanes II extend out from tube I8 between baille l9 and plate l6, and similar radial vanes 22 extend'between baille l9 and plate l1. Both sets of radial varies terminate approximately in line with the circumferential edge of plate II. The radia-l vanes function both to position dome shaped baille it between plates I 6 and I! and to dirct'flowof cooling water through the disk.
For cooling the valve water is introduced through tube It and flows through the passages which are defined by lower plate It, baffle I9 and radialvanes 2| and then into pipe Ill. The water is discharged from pipe I 5 via the passages which are defined by upper plate l1, baffle l9 and radial vanes and then through stem H. The crosssectional area of tube It is at least as great as the total inlet orifice area from the lower passages into pipe IS, in order not to retard water circulation. Preferably the areas of the inlet and discharge orifices of pipe it are substantially equal. The flow of water thus continuously cools pipe I! throughout its circumference.
A dome shaped insulation block 24 of refractory material is fixed to the underface of plate It. A conical insulation block 25 of similar refractory material is fixed to the upper face of plate I'I. Preferably pipe l5 carries external circumferential wings 26 and 21 for retaining said insulation blocks.
When the valve disk is seated against seat l2, pipe 15 may flex slightly at its juncture with lower plate IS-to furnish a close fit against the seat. The line of juncture may be necked-down" slightly as indicated at 28 in Figure 2 to assist such flexing. However, any such flexing must not be of suflicient magnitude to crack insulation block 24. 7
From the foregoing description, it is seen that I have provided an improved closure disk for valves adapted to control the fiow of high temperature gases. The valve disk has a highly efficient water circulating system in which all metal parts are continuously cooled and the exposed metal parts are protected insofar as possible by refractory insulation. The sealing means shown provides a complete seal against passage of gases 5; when the valve is closed.
