OTTILIE KUERS, geb. TIEBEL in STERNBERG (Reg.-Bez. Frankfürt a. O.).OTTILIE KUERS, née TIEBEL in STERNBERG (Reg.-Bez. Frankfürt a. O.).
Sicherheits-Apparat zur Verhinderung des thermischen Siedeverzuges bezw. zur Anzeige durch ihn drohender Gefahren.Safety apparatus to prevent thermal boiling delay BEZW. to the Indication of imminent dangers by him.
Patentirt im Deutschen Reiche vom 25. Juli 1878 ab.Patented in the German Empire on July 25, 1878.
Der Haupttheil des Apparates ist ein hohler, aus wellenförmig geprefsten oder glatten Scheiben gebildeter Körper A, welcher ganz mit Wasser oder einer anderen Flüssigkeit gefüllt und vermittelst einer Zugstange mit einem Glockenventil B verbunden ist. Derselbe berührt die vom Feuer am meisten bespülte Stelle der Kesselbleche und ist die Elasticität und die Stärke der Wandungen von A dem Drucke, für welchen der Dampfkessel concessionirt wurde, angepafst, und zwar so, dafs unter Berücksichtigung des im Dampfkessel auf A wirkenden , Gegendruckes bei dem concessionirten Maximaldruck ein OefFnen des Glockenventils erfolgt. Der Druck in dem gefüllten hohlen Körper A wird durch die Wärme der Kesselwände bezw. des Kesselwassers erzeugt und durch den Dampfdruck im Kessel reducirt. Bei entstehendem Siedeverzuge wird das Kesselwasser über den dem Dampfdrucke entsprechenden Hitzegrad erwärmt und infolge dessen auch der Körper A. Es soll hierdurch eine Ausdehnung von A und daher ein Oeffnen. des Glockenventils stattfinden, wodurch sofort der Siedeverzug ausgeglichen wird. Ebenso soll eine Ausdehnung des Körpers A stattfinden bei der Entblöfsung desselben vom Kesselwasser, auch bei Anhäufung von Kesselstein. Durch die Schraube c wird die Länge der Zugstange justirt.The main part of the apparatus is a hollow body A made of corrugated pressed or smooth disks, which is completely filled with water or some other liquid and connected to a bell valve B by means of a pull rod. It touches the part of the boiler plates that is most swept by the fire, and the elasticity and strength of the walls of A are adapted to the pressure for which the steam boiler was licensed, in such a way that, taking into account the counter-pressure acting on A in the steam boiler, at The bell valve is opened at the concessioned maximum pressure. The pressure in the filled hollow body A is BEZW by the heat of the boiler walls. of the boiler water and reduced by the steam pressure in the boiler. If there is a delay in boiling, the boiler water is heated above the degree of heat corresponding to the steam pressure and, as a result, also the body A. This is supposed to cause an expansion of A and therefore an opening. of the bell valve take place, which immediately compensates for the delayed boiling. Likewise, an expansion of the body A should take place when it is defleacted by the boiler water, also when boiler scale accumulates. The length of the pull rod is adjusted with screw c.
Der aus dem Ventile ausströmende Dampf giebt durch die Dampfpfeife das Warnungssignal. Die verticale Bewegung der Zugstange wirkt aufserdem auf einen Zeiger, welcher hierdurch die Veränderungen des Körpers A auf einer angebrachten Scala anzeigt.The steam flowing out of the valve gives the warning signal through the steam whistle. The vertical movement of the pull rod also acts on a pointer, which thereby shows the changes in the body A on an attached scale.
