Der nachstehend beschriebene Erfindungsgegenstand ist ein Druckverminderungsventil mit Hochdruckdampf belastung für den Niederdruckzylinder einer Verbunddampfmaschine und ist auf der beiliegenden Zeichnung dargestellt. Derselbe besteht in einem selbsttätig wirkenden Ablaßventil 4, das einen vom Ar beitsdampf des Niederdruckzylinders erfüllten Raum 2 gegen einen Austrittsraum 3 abschließt und mit einem Kolbenansatz 5 in einen unter Hochdruckzylinder-Eintrittsdampf stehenden Raum ι hineinragt, dessen Trennungswand 6 vom Austrittsraum 3 in bekannter Weise, z. B. durch Stopfbüchse, dampfdicht und verschiebbar durchdringend,The subject matter of the invention described below is a pressure reducing valve with high pressure steam loading for the low pressure cylinder of a compound steam engine and is shown on the accompanying drawing. The same thing consists in an automatic acting drain valve 4, which met a beitsdampf from the low pressure cylinder Space 2 closes off against an outlet space 3 and with a piston attachment 5 in a lower High-pressure cylinder inlet steam standing space ι protrudes, the partition wall 6 from the outlet space 3 in a known manner, for. B. by stuffing box, steam-tight and displaceable penetrating,
Der Hochdruckzylinder-Eintrittsdampf ruht auf der Fläche 7 des Ablaßventils 4 und hält dem auf der Fläche 8 dieses Ventils lastenden Niederdruckzylinder-Arbeitsdampf das Gleich-The high pressure cylinder inlet steam rests on the surface 7 of the drain valve 4 and holds the low-pressure cylinder working steam on the surface 8 of this valve has the same
äo gewicht, wenn beide Flächendrücke sich gleichbleiben. Wird dieses Gleichgewicht durch Anwachsen des Niederdruckes im Räume 2 gestört, dann hebt sich das Ventil 4 und läßt den Drucküberschuß aus dem Räume 2 nach dem Austrittsraum 3 ab, bis wieder Gleichgewicht eingetreten ist.eo weight if both surface pressures remain the same. If this equilibrium is achieved by increasing the low pressure in room 2 disturbed, then the valve 4 lifts and lets the excess pressure from the room 2 to the outlet space 3 until equilibrium has been reached again.
Die seither bekannten Niederdruckzylinder-Sicherheitsventile oder Druckverminderungsventile dieser Art sind nur einem bestimmten' Betriebsdrucke entsprechend belastet. Die vorliegende Erfindung stellt die der wechselnden Eintrittsspannung entsprechende Belastung eigenartig selbsttätig ein. Es wird die neuartige Wirkung erzielt, daß der Dampfdruck im Niederdruckzylinder von Verbundmaschinen, u. a. beim Anlassen derselben mittels Hochdruckdampfes nach dem Niederdruckzylinder hin, nicht über die bei dem gegebenen Gesamtexpansionsverhältnis aus der jeweiligen Eintrittsspannung des Hochdruckzylinders resultierende Niederdruckzylinder-Eintrittsspannung anwachsen kann, wenn die beiden Druckflächen 7 und 8 dieses Druckverminderungsventils 4 in dem umgekehrten Verhältnis dieser beiden Eintrittsspannungen von Hoch- und Niederdruckzylinder zueinander bemessen worden sind.The low-pressure cylinder safety valves known since then or pressure reducing valves of this type are only loaded according to a certain operating pressure. The present The invention adjusts the load corresponding to the changing inlet voltage strangely automatically. It will be the novel Effect achieved that the steam pressure in the low pressure cylinder of compound machines, i.a. when starting the same by means of high pressure steam after the low pressure cylinder out, not over the given total expansion ratio from the respective Inlet voltage of the high pressure cylinder resulting low pressure cylinder inlet voltage can grow when the two pressure surfaces 7 and 8 of this pressure reducing valve 4 has been measured in the inverse ratio of these two inlet voltages of the high and low pressure cylinders to one another are.
