PATENTAMT.PATENT OFFICE.
Die vorliegende Erfindung behandelt die Abdichtung der Kühlrohre bei Oberflächenkondensatoren. Es sind zwei Ausführungen, welche den Überdruck des Kühlwassers gegenüber dem Vakuumraum nutzbar machen, bisher bekannt. Die eine von diesen benötigt Spezialstirnwände, um die zylindrischen Gummihülsen aufbringen zu können, während bei der anderen Rundgummiringe AnwendungThe present invention is concerned with sealing the cooling tubes in surface condensers. So far, there are two versions that make the excess pressure of the cooling water usable in relation to the vacuum space known. One of these requires special end walls around the cylindrical rubber sleeves to be able to apply, while using the other round rubber rings
ίο finden, welche bei plötzlichem Vakuumabfall sehr leicht Kühlwasser in den Kondensator eindringen lassen, da sie nur eine sehr kleine Dichtungsfläche haben, und die Gefahr besteht, daß dieselben durch den Konus im Rohrboden hochgedrückt werden.ίο find which one in the event of a sudden vacuum drop very easily let cooling water penetrate into the condenser, since it is only a very small one Have sealing surface, and there is a risk that the same through the cone in the tube sheet be pushed up.
Demgegenüber ist bei der vorliegenden Erfindung die in der Hydraulik bestens bewährte Stulpdichtung zur Anwendung gebracht, und zwar kann dieser Stülp entweder aus Gummi, Leder oder anderem elastischen Material hergestellt werden. Durch das Anbringen eines Metallringes in die inneren Wände dieses Stulpes wird eine Außenpressung auf das Kühlrohr sowohl als auf den Kondensatorrohrboden ausgeübt, und zwar erhält der Gummiring durch diese eine Vorpressung, welche so groß ist, daß bei einem plötzlichen Vakuumabfall ein Rückschlag derselben und somit ein Eindringen von Kühlwasser in den Kondensator verhindert wird. Diese Druckwirkung wird während des Betriebes des Kondensators, also bei herrschendem Vakuum, durch den Überdruck des Kühlwassers entsprechend erhöht, so daß eine zuverlässige Abdichtung bei geringen Herstellungskosten erreicht ist.In contrast, in the present invention, the one that has proven its worth in hydraulics Forend seal brought to use, and this can either be made of rubber, Leather or other elastic material can be made. By attaching a Metal ring in the inner walls of this faceplate is an external pressure on the Cooling tube both as exerted on the condenser tube sheet, namely the rubber ring through this a pre-compression which is so great that in the event of a sudden vacuum drop a kickback of the same and thus a penetration of cooling water into the condenser is prevented. This pressure effect is generated during the operation of the condenser, so with the prevailing vacuum, increased accordingly by the excess pressure of the cooling water, so that a reliable seal is achieved at low manufacturing costs.
Die beiliegende Zeichnung zeigt eine Ausführungsform dieser neuen Dichtung, und zwar stellt die Figur die Abdichtung mittels Gummistulpes A und eingelegten Messingringes B dar. Es ist aus der Zeichnung ersiehtlieh, daß die Dichtungsfläche sowohl nach der Rohrseite wie nach der Stirnwand hin weitaus größer als bei einfachem Rundgummiring ausfällt.The accompanying drawing shows an embodiment of this new seal, namely the figure represents the seal by means of rubber cuffs A and inserted brass ring B. It can be seen from the drawing that the sealing surface is much larger both towards the pipe side and towards the end wall than with a simple one Round rubber ring fails.
