Definitions

  • a water-cooled valve disk is provided in the a corporanon of Pennsylvama usual form of a circular hollow body with a peripheral wall in which two transversely extending flow-confining walls form a [54] WATER COOLED VALVE DISK FOR GATE channel and extend from the peripheral wall to the central VALVES area of the disk with a port in the periphery opening into said 9 Claims, 1 Drawing Fig channel and there are a plurality of concentric flow-confining walls, the outermost one of which 18 spaced from the [52] US.
  • valves of the type used for example in controlling the flow of highly heated air in blast furnace installations, and elsewhere, are commonly provided with a water-cooled valve gate in the form of a hollow disc with internal walls forming more or less concentric channels. Water supply and exhaust lines are connected to adjacent locations on the peripheral wall of the valve disc. The concentric passages are so arranged that water may flow from the periphery to the center in concentric communicating passages and then out from the center to the outlet pipe, or in the reverse direction.
  • a typical valve gate of this type is disclosed in U.S. Pat. No. 3,266,517 to l-Iugh B. Carr.
  • the present invention provides a valve disc of construction wherein the number of concentric passages may be increased and which is not limited to two concentric partition walls, but three or more such walls may be provided whereby the water channels may be smaller in section and thereby secure a greater flow velocity of the cooling water. This enables less water to be used in smaller sizes of valves and enables large valve discs, such as those eight feet or more in diameter, to have a greater number of smaller passages than have heretofore been possible.
  • a hollow valve disc 1 is shown positioned in a gate valve 39.
  • the gate valve is of conventional structure and has a gate valve body 40, a removable bonnet 41, with stuffing boxes 43 thereon, yoke 45, cleaning traps 51 and lines 47 and 49 for cooling.
  • the gate valve construction is conventional and particularly described in U.S. Pat. No. 3,266,517 and, while forming no part of the present invention, illustrates an environment and utility of the valve disc herein claimed.
  • the valve disc 1 has a closed peripheral wall 3 with outlet port 5 and inlet port 7 thereon. Although it is possible to reverse the flow of water or other coolant through the valve disc 1, for the purpose of clarity and brevity. the disc will be described as illustrated in its preferred embodiment shown in the drawing with the outlet port having a channel 9 extending inwardly therefrom transverse the disc and inlet means 7 adjacent thereto.
  • the outlet port 5 and inlet port 7 are positioned on opposed sides of a diameter D of the valve disc with a first and second flow channel forming walls 13 and 11 extending from port 5 into the central area of the disc and terminating in the central area, forming a channel 9.
  • the channel 9 extends a short distance beyond a second diameter d of the disc that is generally normal to the diameter D.
  • the first wall 13 of the chamber 9 preferably terminates as an inwardly extending leg 15 generally parallel to the diameter (1 while the second wall 11 of channel 9 is spaced from and extends around the leg 15 and terminates at 19, generally parallel to diameter D, a distance from the first wall 13.
  • a pair of spaced concentric walls 21 and 27 extend from the first wall 13.
  • Concentric wall 21 extends from first wall 13 towards the peripheral wall 3 of the disc to a point 23, spaced from the first wall 13 and peripheral wall 3, and continues in a circular path, a spaced distance from the peripheral wall 3 terminating at 25, in spaced relation to the second wall 11.
  • the spaced concentric wall 27 also extends from first wall 13 toward the peripheral wall 3 to a point 29 where it then continues circularly, spaced from peripheral wall 3 and concentric wall 21, until it terminates at 31, in spaced relation to second wall 11.
  • An opposed second concentric spaced wall 33, intermediate concentric walls 21 and 27 extends from second wall 11 and in a spaced circular path to a point 34 where it assumes a generally spaced position between concentric walls 21 and 27 and terminates at 35 in spaced relation to first wall 13.
  • all concentric walls are spaced so that the distance between adjacent such walls corresponds to the width of channel 9.
  • the second wall 11 of the channel 9 extends around the leg 15 with a spacing so that the spacing between leg 15 and second wall 11, and terminal 19 are substantially the same.
  • a baffle 37 is positioned on the peripheral wall 3 and extends inwardly so as to direct a stream from inlet port 7 towards the first wall 13 of channel 9.
  • An adjacent countercurrent flow f will be provided between concentric wall 27 and opposed second concentric wall 33 until striking first wall 13 of channel 9, around terminal point 35 of second concentric wall 33 where reverse flow again occurs to give a flow f between second concentric wall 33 and concentric wall 21 in countercurrent flow to adjacent flow f but in the same direction as flow f between peripheral wall 3 and concentric wall 27.
  • the streamcontacts second wall 11 of channel 9 flows around terminal 25 and in reverse flow 1 through the space between second wall 11 including extension 17, and concentric wall 21, around terminal point 19 and by reverse flow is fed into channel 9 and directed out of outlet port 5 and discharged from the valve disc.
  • This stream is thus fed to the disc through inlet port 7, passed through the disc in a series of concentric, countercurrent flow paths towards the center of the disc and then directed through exhaust channel 9 out of outlet port 5.
  • outlet port 5 and inlet port 7 can be reversed so that the initial flow of coolant will be fed through port 5 to the center of the valve and as eccentric countercurrent streams to the periphery of the disc and then out of the other port 7 for discharge from the disc, although the construction illustrated in the drawing is preferred.
  • valve disc'of the present invention permits increased velocity of the coolant through the disc and therefore provides better cooling of the disc.
  • the disc is formed generally of metallic material and preferably of copper so as to provide a resistance to water when water is used as coolant,
  • a particularly useful valve disc has been produced having a diameter of about 36 inches, with walls therein of one-half inch thickness and spacing for coolant flow of about 3 inch width.
  • the present invention can of course be used for any size valve disc with the dimensions determined by the size of the gate valve opening for the disc and other considerations.
  • a water cooled valve disc comprising a circular hollow body with a peripheral wall and having adjacent inlet and outlet ports on the peripheral wall, said body having first and second spaced flow channel forming walls extending from one port into the central area of the disc and terminating in said central area,
  • At least one second concentric wall extending from said second wall and terminating in spaced relation to said first wall, said second concentric wall being spaced midway between adjacent first two concentric walls,
  • a water-cooled valve disc as defined in claim 1 in which there is a baffle attached to the peripheral wall and arranged to direct the flow of water between said other port and the space between the peripheral wall and the outermost of said concentric walls against the closest of said flow channel forming walls.
  • a water-cooled valve disc comprising a circular hollow body having a peripheral wall, wherein the interior of the body has flow directing walls arranged to provide a plurality of concentric flow passages in which the direction of flow is alternately reversed in each concentric passage characterized b a. first and second spaced flow directing walls extending in a direction transverse the valve body from the peripheral wall into the central area where said first and second walls terminate and forming between them a flow passage; b. a port in the peripheral wall of the disc opening into said passage defined between said first and second walls; c.
  • At least two concentric walls extending circularly from said first wall towards but terminating in spaced relation to said second wall, said concentric walls being spaced from each other with the outermost being spaced 'l'rom the peripheral wall and the innermost being spaced outwardly from the terminals olsaid first and second walls; d. at least one further concentric wall extending circularly from said second wall tow ard but terminating in spaced relation to said first wall div ding the space between said concentric walls into separate channels;
  • a hollow valve disc having a closed circular interior, inlet and outlet ports at the disc periphery on opposed sides of a diameter of the disc, an exhaust channel; formed by first and second wallsextending inwardly from the outlet port a short distance beyond a second diameter of said disc normal to said diameter, and a plurality of concentric spaced walls. spaced from said periphery and from each other, positioned so as to direct a fluid stream from said inlet port in adjacent countercurrent concentric flow towards the center of the disc and out of said disc through the exhaust channel.
  • said plurality of concentric spaced walls consists of a pair of concentric walls extending from said first wall towards said periphery and in a spaced circular path from said periphery terminating in spaced relation to said second wall, and an opposed concentric wall extending intermediate said pair extending from said second wall and in a spaced circular path terminating in spaced relation to said first wall.
