PATENTAMT.PATENT OFFICE.
Diese Einrichtung ist bestimmt, bei Niederdruck-Dampfheizungen das Sicherheits- bezw. Abblaseventil bei Hochdruckheizungen zu ersetzen. Der geringe Dampfdruck im Dampfkessel mit offenem Standrohr von im Maximum 5 m Höhe ist nicht geeignet,. gewöhnliche Sicherheitsventile mit Zulässigkeit zu benutzen. Wenn daher durch nachlässige Bedienung der Dampfdruck über den angewendeten Maximaldruck steigt, wird das Wasser aus dem Kessel herausgeschleudert. Die angegebene Vorrichtung verhindert dieses und läfst, wie bei anderen Dampfkesseln, den Dampf heraus.This device is intended for low-pressure steam heating the security resp. Replace blow-off valve in high-pressure heating systems. The low steam pressure in the steam boiler with an open standpipe with a maximum height of 5 m is not suitable. ordinary Use safety valves that are permitted. If, therefore, negligent operation of the If the steam pressure rises above the applied maximum pressure, the water is removed from the boiler thrown out. The specified device prevents this and works, as with others Steam boilers, the steam out.
Zwei geschlossene Kasten M und JV sind mit einander mittelst zweier Röhren c und e verbunden. Das Rohr w steht in Verbindung mit dem Wasserraum des Kessels, so dafs der Wasserstand in JV so hoch steht wie im Kessel. Das Rohr d steht in Verbindung mit dem Dampfraum des Kessels. Steigt der Druck im Kessel über das gewünschte Mafs, so drückt der Dampf das Wasser durch das Rohr c aus dem Kasten JV in den Kasten M, bis es durch das Rohr α abläuft. Ist das Wasser im Kasten JV" so weit gefallen, dafs das untere Ende des Rohres e über dem Wasserspiegel steht, so entweicht der Dampf durch die Rohre e und a ins Freie, bis der Druck im Kessel wieder so weit gefallen ist, dafs das Wasser, welches den Kasten M füllt, durch das Rohr c in den Kasten JV zurücklaufen kann und den Wasserverschlufs wieder herstellt. Eine etwa verloren gegangene kleine Wassermenge ersetzt sich nach und nach durch das enge Rohr w vom Kessel. Ein solches Steigen des Dampfdruckes infolge unzuverlässiger Bedienung geschieht gewöhnlich rapide und der Apparat wird in diesem Falle ohne nennenswerthe Wasserverluste wirken.Two closed boxes M and JV are connected to one another by means of two tubes c and e . The pipe w is in connection with the water space of the boiler, so that the water level in JV is as high as in the boiler. The pipe d is in communication with the steam space of the boiler. If the pressure in the boiler rises above the desired level, the steam pushes the water through the pipe c out of the box JV into the box M until it drains through the pipe α. If the water in the box JV "has fallen so far that the lower end of the tube e is above the water level, the steam escapes through the tubes e and a into the open air until the pressure in the boiler has fallen again so far that the water is again which fills the box M , can run back through the pipe c into the box JV and re-establishes the water seal. A small amount of water that may have been lost is gradually replaced by the narrow pipe w from the boiler. Such an increase in steam pressure due to unreliable operation usually happens rapidly, and in this case the apparatus will work without any appreciable loss of water.
Das Rohr mit der Pfeife ρ giebt durch einen Ton den Vorgang an, wodurch der Heizer zur Beseitigung der Mangel in der Bedienung gerufen wird.The pipe with the whistle ρ indicates the process by a tone, whereby the stoker is called to remedy the deficiency in the operation.
Das Rohr n> erhält einen Probir-Dreiweghahn; durch Drehung desselben kann man sich überzeugen, dafs das enge Rohr w nicht verstopft ist. Die Kasten M und JV können Wasserstandsgläser erhalten, damit man den Wasserstand ablesen kann; dieselben sind jedoch zur Wirkung des Apparates nicht nothwendig. The pipe n> receives a Probir three-way stopcock; by turning it one can convince oneself that the narrow tube w is not clogged. Boxes M and JV can contain water level glasses so that the water level can be read; however, these are not necessary for the operation of the apparatus.
