Description
Gekühlte Schieberplatte Bei wassergekühlten Heißwindschieberplatten ist es bekannt, zur Führung des Kühlwassers Querwände anzuordnen mit dem Ziel, eine gleichmäßige Kühlung des Schiebers zu erreichen. Hierbei hat sich aber gezeigt, daß eine gleichmäßige und ausreichende Wasserströmung dadurch gestört wird, daß sich in den Wasserkanälen Luftsäcke bilden. Infolgedessen und bei Benutzung namentlich rückgekühlten Kühlwassers gelangt an den nicht vom Wasser berührten Flächen Schlamm zur Ablagerung, so daß im Bereiche dieser Stellen die Schieberplattenwandungen einer schnellen Zerstörung durch Verbrennen ausgesetzt sind.Cooled valve plate For water-cooled hot air valve plates it is known to arrange transverse walls to guide the cooling water with the aim of a to achieve uniform cooling of the slide. However, it has been shown here that an even and sufficient flow of water is disturbed by the fact that air sacs form in the water channels. As a result and when using it by name Recooled cooling water reaches the surfaces that are not in contact with the sludge for deposition, so that in the areas of these points the slide plate walls of a are exposed to rapid destruction by burning.
Gegenstand der Neuerung ist eine Schieberplattenausbildung, welche die genannten Nachteile verhütet und der Schieberplatte eine wesentlich erhöhte Lebensdauer verleiht. Der Kühlwasserraum ist durch Querwände in spiralförmige Kanäle unterteilt, durch die das Kühlwasser im Gegenstrom geleitet wird. Hierbei werden erfindungsgemäß Schlammablagerungen und Luftsäcke vermieden, indem im Bereich des oberen Schieberteils die Querwände mit Öffnungen versehen sind, durch welche die in den Wasserkanälen vorhandene Luft ohne weiteres zum Wasseraustritt gelangt. Dadurch erhält der Wasserstrom- stets eine geschlossene Form und gleichmäßige Strömung, wodurch jegliche Schlammablagerung vermieden wird.The object of the innovation is a slide plate training, which prevents the disadvantages mentioned and the slide plate a significantly increased Longevity gives. The cooling water space is through transverse walls in spiral channels divided through which the cooling water is passed in countercurrent. Here will be According to the invention, sludge deposits and air pockets avoided by in the area of the upper slide part, the transverse walls are provided with openings through which the Air present in the water channels easily reaches the water outlet. Through this the water flow - always a closed shape and steady flow, thereby avoiding any sludge build-up.
Die Zeichnung veranschaulicht einen senkrechten Schnitt durch eine Heißwindschieberplatte.The drawing illustrates a vertical section through a Hot blast gate valve.
a bezeichnet die spiralförmigen Querwände, und b sind die Lüftungsöffnungen. Das Kühlwasser tritt bei c ein und verläßt die Schieberplatte bei d.a denotes the spiral-shaped transverse walls, and b are the ventilation openings. The cooling water enters at c and leaves the gate at d.
Der Erfindungsgegenstand ist außer für Heißwind- und Heißgasschieberplatten auch für sonstige heißen Temperatureinflüssen ausgesetzte, wassergekühlte, schieb- oder drehbare Verschlußmittel gedacht.The subject of the invention is except for hot blast and hot gas gate plates also for other hot temperature influences exposed, water-cooled, sliding or rotatable locking means.
