Schlußstellung gelangt.Final position reached.
Es sind bereits selbsttätige Abschlußvorrichtungen für Dampfleitungen bekannt geworden, die unter Vermittlung eines elektrischen Stromes in ihrer Offenstellung gehalten werden, während sie in ihre Abschlußstellung gelangen, sobald die elektrische Leitung stromlos wird. Auch die neue Rohrbruchsicherung β gehört zu dieser Art, sie unterscheidet sich aber von den bisher bekannt gewordenen Einrichtungen dadurch, daß bei Rohrbruch ein um die Dampfleitung gewickeltes Band ο. dgl. aus einem Stoff von niedrigem Schmelzpunkt durch den ausströmenden Dampf durchgeschmolzen wird.There are already automatic locking devices for steam lines become known, which are held in their open position by means of an electric current, while they move into their closed position as soon as the electrical line is de-energized. The new pipe rupture protection β also belongs to this type, but it differs from the previously known devices in that in the event of a pipe rupture, a tape o wrapped around the steam line. Like. Is melted from a substance of low melting point by the escaping steam.
Auf der beiliegenden Zeichnung ist der Erfindungsgegenstand in Fig. I schematisch dargestellt; Fig. 2 zeigt die Seitenansicht der elektrischen Auslösevorrichtung.In the accompanying drawing, the subject matter of the invention is shown schematically in FIG shown; Fig. 2 shows the side view of the electrical release device.
In Fig. ι ist α eine Drosselklappe, welche in die Dampfleitung kurz hinter dem Dampfkessel eingeschaltet wird; b ist die Rohrleitung, die in gewöhnlicher Weise mit einem Wärmeschutzmantel umgeben ist. Auf diesen ist in Schraubenwindungen ein Band oder Draht c aus einer leicht schmelzbaren Metallegierung aufgebracht.In Fig. Ι α is a throttle valve, which is switched into the steam line just behind the steam boiler; b is the pipeline, which is usually surrounded by a thermal protective jacket. A tape or wire c made of an easily fusible metal alloy is applied to this in screw turns.
Das Band c steht mit einer Ruhestrornbatterie d in Verbindung, in deren Stromkreis ein Elektromagnet e eingeschaltet ist, der den um eine Achse drehbaren Anker f bei. eingeschaltetem Strom in wagerechter Lage erhält. Von dem Hebel der Drosselklappe α führt eine Stange g zu dem Gewichtshebel h, der in betriebsfertigem Zustand durch die Stange i in wagerechter Lage erhalten wird und dabei. die Drosselklappe a offen hält. Die Stange i wird durch eine Feder k nach rechts gedrückt, doch hindert sie der Anschlag Z in Verbindung mit der Sperrvorrichtung m an der Ausführung dieser Bewegung.1 The band c is connected to a quiescent current battery d , in the circuit of which an electromagnet e is switched on, which supports the armature f , which is rotatable about an axis. switched on current receives in horizontal position. A rod g leads from the lever of the throttle valve α to the weight lever h, which is obtained in the operational state by the rod i in the horizontal position and thereby. the throttle valve a keeps open. The rod i is pressed to the right by a spring k , but the stop Z in conjunction with the locking device m prevents it from executing this movement. 1
Die Wirkungsweise der Vorrichtung ist folgende: Sobald an irgend einer Stelle die Rohrleitung bricht, muß der ausströmende heiße Dampf das Band c durchschmelzen und dadurch den Stromkreis unterbrechen. Hierbei läßt der Elektromagnet e den Anker f fallen, welcher nach unten ausschwingt und dadurch die Sperrvorrichtung m auslöst (s. Fig. 2). Nunmehr schnellt die Stange i unter dem Einfluß der Feder k nach rechts und gibt dabei den Hebel h frei, welcher mit dem gewichtbelasteten Ende nach unten fällt und dadurch die Drosselklappe α schließt.The mode of operation of the device is as follows: As soon as the pipeline breaks at any point, the hot steam flowing out must melt through the band c and thereby interrupt the circuit. Here, the electromagnet e lets the armature f fall, which swings out downwards and thereby triggers the locking device m (see FIG. 2). Now the rod i snaps to the right under the influence of the spring k and releases the lever h , which falls down with the weight-loaded end and thereby closes the throttle valve α.
Statt der Drosselklappe kann auch irgend eine andere Abschlußvorrichtung vorgesehen werden, wie überhaupt die ganze Anordnung der Auslösevorrichtung nur beispielsweise gewählt ist.Instead of the throttle valve, any other closing device can also be provided be, like the whole arrangement of the trip device only for example is chosen.
