KLASSE 13: Dampfkessel nebst Ausrüstung.CLASS 13: Steam boiler and equipment.
Sicherheitsvorrichtung.Safety device.
Patentirt im Deutschen Reiche vom 30. August 1884 ab.Patented in the German Empire on August 30, 1884.
Der auf der Zeichnung in zwei Modificationen dargestellte Apparat dient dazu, beim Ueberschreiten eines bestimmten Druckes eine selbstthätige Ausgleichung herbeizuführen.The apparatus shown in two modifications on the drawing is used for To bring about an automatic equalization when a certain pressure is exceeded.
Durch den Kanal K steht der Cylinder A des Apparates mit dem Innern des Dampfkessels etc. in Verbindung. Ein in dem Cylinder befindlicher Kolben B wird durch ein Gewicht P, Fig. 1 und 2, oder eine Feder R, Fig. 4, nach dem Verbindungskanal K hin gedrückt.The cylinder A of the apparatus is connected to the interior of the steam boiler etc. through channel K. A piston B located in the cylinder is pressed towards the connecting channel K by a weight P, FIGS. 1 and 2, or a spring R, FIG.
Tritt nun bei der ersteren Construction, Fig. ι und 2, eine den Gegendruck des Gewichtes P überschreitende Druckerhöhung im Innern des Kessels etc. ein, so wird der Kolben B vorwärts geschoben und seine gezähnte Kolbenstange F veranlafst dadurch ein Schwingen des mit dem Gewichtshebel L verbundenen Segmentes C. Auf der Achse M des Segmentes sitzt aber auch das Küken D eines Hahnes Z, welcher durch den Kanal T gleichfalls mit dem Kessel etc. und aufserdem durch einen Ablafsstutzen mit der freien Atmosphäre communicirt. Die Drehung des Kükens bewirkt also, dafs die beiden Bohrungen X und Y des Kükens die Verbindung zwischen T und dem Ablafsstutzen herstellen, so dafs also ein Ausströmen des Dampfes oder dergleichen aus dem Kessel stattfindet. Durch eine entsprechende Hebelverbindung kann man das Ueberschreiten des Druckes auch mittelst einer Pfeife J hörbar, sowie auch an einer Scala J mit Zeiger sichtbar machen.If, in the first construction, FIGS. 1 and 2, a pressure increase in the interior of the boiler etc. that exceeds the counterpressure of the weight P occurs, the piston B is pushed forward and its toothed piston rod F causes the piston with the weight lever L to oscillate connected segment C. On the axis M of the segment, however, there is also the plug D of a cock Z, which communicates through the channel T likewise with the boiler etc. and furthermore through a discharge nozzle with the free atmosphere. The rotation of the plug has the effect that the two bores X and Y of the plug establish the connection between T and the drainage socket, so that the steam or the like flows out of the boiler. By means of a corresponding lever connection, the exceeding of the pressure can also be made audible by means of a whistle J and also made visible on a scale J with a pointer.
Fig. 3 zeigt die Anordnung des Kükens D, wenn mehrere Auslaufbohrungen V in eine Ablafsbohrung W münden.3 shows the arrangement of the plug D when a plurality of outlet bores V open into a drain bore W.
Fig. 4 erläutert die Einrichtung des Apparates für Lokomotiven, Lokomobilen etc., bei welcher an Stelle des Gewichtes P eine sich an den Flantsch N der Kolbenstange F einerseits und an den Deckel S des Schieberkastens D andererseits anstemmende Feder R angewendet ist. In dem Schieberkasten D bewegt sich ein Kolbenschieber B1, dessen Oeffnungen R mit den Bohrungen O des Schieberkastens communiciren. Fig. 4 explains the device of the apparatus for locomotives, locomotives, etc., in which instead of the weight P a spring R is applied to the flange N of the piston rod F on the one hand and to the cover S of the valve body D on the other hand. A piston valve B 1 moves in the valve body D , the openings R of which communicate with the bores O of the valve body.
Die Vorrichtung läfst sich auch zur Begrenzung eines Vacuumgrades verwenden; nur hat in diesem Falle die Belastung umgekehrt zu wirken, d. h. den Kolben B von dem Kanal K wegzudrücken.The device can also be used to limit a degree of vacuum; only in this case the load has to act in reverse, ie to push the piston B away from the channel K.
