KLASSE 13: Dampfkessel nebst Ausrüstung.CLASS 13: Steam boiler and equipment.
Patentirt im Deutschen Reiche vom 11. März i886 ab.Patented in the German Empire on March 11, 1886.
Die Absperrvorrichtung soll ermöglichen, beim Zerspringen des Wasserstandsglases sofort den Austritt des Wassers oder des Dampfes zu verhindern.The shut-off device should make it possible immediately if the water level glass shatters to prevent the escape of water or steam.
Fig. ι beiliegender Zeichnung stellt einen Wasserstandsglashalter mit geschlossenem Ventil im Verticalschnitt dar,Fig. Ι the accompanying drawing shows a water level glass holder with a closed valve in vertical section,
Fig. 2 denselben von oben,Fig. 2 the same from above,
Fig. 3 einen WTasserstandsglashalter im Schnitt mit geöffnetem Ventil,Fig. 3 is a W T asserstandsglashalter in section, with the valve open,
Fig. 4 denselben von vorn gesehen. .4 the same seen from the front. .
In Fig. 5 ist die Spindel S und die Ventilklappe ν in zwei Ansichten abgebildet.In Fig. 5, the spindle S and the valve flap ν are shown in two views.
Die Wasserstandsglashalter werden durch die Flantschen A mit dem Kessel verbunden. In dem oberen und unteren Halter ist das Wasserstandsglas B mit seinen Enden eingedichtet. The water level glass holders are connected to the kettle with the flanges A. In the upper and lower holder, the water level glass B is sealed with its ends.
Die Schraube D ist angeordnet, um mit einem Draht durch den Kanal ο stofsen zu können. Durch die Oeffnung C kann beim oberen Halter das Wasserstandsglas in denselben eingeführt werden, beim unteren Halter wird darin der Ablafshahn eingeschraubt.The screw D is arranged so that a wire can be pushed through the channel ο. The water level glass can be inserted into the upper holder through the opening C, the drainage tap is screwed into the lower holder.
Ist das Glas B eingesetzt, so bringt man den Gewichtshebel H des oberen und unteren Halters in die in Fig. 3 dargestellte Lage, wodurch der Kanal 0 geöffnet und der Eintritt des Wassers bezw. Dampfes in das Glasrohr B ermöglicht wird. Der Hebel H bleibt in dieser Lage stehen, da der Daumen e ein Herunterfallen desselben verhindert. Soll der Zutritt des Wassers bezw.· Dampfes in das Glas verhindert werden, so legt man den Hebel H in die in Fig. 2 gezeichnete Lage; dadurch schliefst die Ventilklappe ν mit ihrer unteren Fläche den Kanal 0, wobei das Gewicht des Hebels H den Druck überwindet, den das Wasser oder der Dampf auf die Ventilklappe ν ausübt.If the glass B is inserted, the weight lever H of the upper and lower holder is brought into the position shown in FIG. Steam into the glass tube B is made possible. The lever H remains in this position because the thumb e prevents it from falling. If the entry of water or steam into the glass is to be prevented, the lever H is placed in the position shown in FIG. 2; as a result, the valve flap ν closes channel 0 with its lower surface, the weight of the lever H overcoming the pressure exerted by the water or steam on the valve flap ν .
Wenn die beiden Oeffnungen ν im oberen und unteren Halter geschlossen sind, so kann ein neues Glas eingesetzt werden, ohne dafs der Maschinist durch den heifsen Dampf oder das siedende Wasser belästigt wird.When the two openings ν in the upper and lower holder are closed, a new glass can be inserted without the machinist being bothered by the hot steam or the boiling water.
Diese Art der Absperrung hat den Vortheil, dafs sie stets sicher und schnell wirkt, da keine Undichtigkeiten der absperrenden Theile eintreten können, ebenso ein Festbrennen, wie es bei Kükenhähnen so häufig vorkommt, ganz ausgeschlossen ist. Nach aufsen ist die Spindel S, an welcher die Klappe ν sitzt, durch Anschrauben einer Ueberwurfmutter M abgedichtet. Damit Undichtigkeiten leicht beseitigt werden können, ist die untere Seite der Ventilklappe ν auf der Stelle, wo sie den Rand der Oeffnung 0 abdichtet, mit Blei oder sonstigem weichen Metall ausgegossen, so dafs nur unter Umständen ein gröfserer Druck auf den Hebelii angewendet werden mufs, um einenThis type of shut-off has the advantage that it always works safely and quickly, since no leaks can occur in the shut-off parts, and burning, as is so often the case with cocks, is completely excluded. The spindle S, on which the flap ν is seated, is sealed to the outside by screwing on a union nut M. So that leaks can be easily eliminated, the lower side of the valve flap ν is filled with lead or other soft metal at the point where it seals the edge of the opening 0, so that a greater pressure only has to be applied to the leverii under certain circumstances, about one
vollständig dichten Verschlufs von ο durch ν zu bewirken, falls die Flächen unrein waren oder nicht ganz dicht schlossen.to bring about a completely tight closure of ο by ν , if the surfaces were unclean or did not close completely tightly.
