Description
DEUTSCHESGERMAN
Die Erfindung betrifft ein vorzugsweise durch ein elektromagnetisches Hilfsventil gesteuertes und durch das abzusperrende Druckmittel betätigtes Ventil, welches die Funktionen eines Absperr-, Einstell-, Regel- und Rückschlagventils in sich vereinigt. Es ist für kalte und heiße, gasförmige und flüssige Durchflußmedien, insbesondere für Dampf, Vakuum und aggressive Medien, geeignet. Das Ventil funktioniert in jeder Einbaulage. Im Kesselspeisebetrieb kann es als Rückschlag- und regelbares Rückspeiseventil gleichzeitig verwendet werden.The invention relates to a preferably controlled by an electromagnetic auxiliary valve and by the pressure medium-operated valve to be shut off, which has the functions of a shut-off, setting, regulating and check valve combined. It is for cold and hot, gaseous and liquid flow media, particularly suitable for steam, vacuum and aggressive media. The valve works in everyone Mounting position. In boiler feed mode, it can act as a non-return valve and a controllable feedback valve at the same time be used.
Bei einem bekannten derartigen Ventil wurde der Kolben mit mindestens einem Kolbenring ausgerüstet. Für die Dosierung des Zuflusses auf die Rückseite des Kolbens müssen aber Gehäusekanäle und Drosselschrauben im Druckmittelweg eingeordnet oder ein Spiel zwischen Kolben und Zylinder vorgesehen· werden. Erfahrungsgemäß werden solche Kanäle oder Drosselstellen bald verstopft.In a known valve of this type, the piston was equipped with at least one piston ring. For metering the inflow to the back of the piston, however, housing channels and throttle screws must be used arranged in the pressure medium path or a clearance between piston and cylinder provided. Experience has shown that such channels or throttling points are soon clogged.
Durch die Erfindung werden diese Nachteile vermieden. Die wesentlichsten Merkmale des erfindungsgemäßen Ventils sind folgende:The invention avoids these disadvantages. The main features of the invention Valve are as follows:
Der Durchfluß des Druckmittels auf die Rückseite des Kolbens erfolgt über den veränderbaren Kolbenringstoß, wodurch Gehäusekanäle und Drosselschrauben im Druckmittelweg eingespart werden. Gegenüber den Ventilen mit Spiel zwischen Kolben· und Zylinder ist die einwandfreie Kolbenführung ein Fortschritt.The flow of the pressure medium to the back of the piston takes place via the changeable piston ring joint, which saves housing channels and throttle screws in the pressure medium path. Opposite to For valves with clearance between piston and cylinder, perfect piston guidance is a step forward.
Es ist auch schon ein Regulierventil bekannt; dessen Verschlußstück mit einem Sprengring ausgerüstet ist, zwischen dessen Enden ein Spalt für den Durchfluß frei bleibt. Infolge Führung des Verschlußstückes mit dem Sprengring in einem konisch ausgebildeten Ventilsitz kann der Spalt in der, Breite verändert werden, woraus sich die Durchflußregelung ergibt.A regulating valve is also known; whose locking piece is equipped with a snap ring, a gap for the flow remains free between the ends. As a result of leadership of the locking piece With the snap ring in a conical valve seat, the width of the gap can be changed from which the flow control results.
Damit auch bei mechanischer Hemmung des Kolbens der mit ihm gekuppelte Magnetanker voll in die Magnetspule gezogen wird, ist die für die Rückholung des Verschluß Stückes des Hilfsventil vorgesehene Zugfeder vorteilhaft zwischen Kolben und Anker befestigt und vorgespannt und dient beiden Aufgaben gleichzeitig. Ähnlich dient eine Druckfeder, die das Verschluß stück des Hauptventils dichtend in den Sitz drückt, gleichzeitig bei mechanischer Hemmung des Magnetankers im Magnetkernrohr der Kompensation der Vorspannung der vorgenannten Zugfeder, so daß das Hauptventil unabhängig von der Stellung des Magnetankers im Schließsinne bewegt werden kann.This means that the armature coupled to it is fully engaged in the piston even when the piston is mechanically blocked When the solenoid is pulled, it is the one provided for retrieving the locking piece of the auxiliary valve The tension spring is advantageously fastened and pretensioned between the piston and armature and serves both purposes simultaneously. A compression spring is used similarly, which seals the closure piece of the main valve in the seat presses, at the same time with mechanical inhibition of the magnet armature in the magnet core tube of the compensation the bias of the aforementioned tension spring, so that the main valve regardless of the position of the Magnet armature can be moved in the closing direction.

Durch die Anordnung einer auswechselbaren Düse, die der Drosselung des Abflusses durch ein mit dem Kolben verbundenes Rohr dient, wird sowohl eine Dämpfung des Öffnungsvorganges des Hauptventils als auch eine Dosierung der Rückstauung bei der Regelfunktion des Ventils erreicht, wobei die leichte Zugänglichkeit der Düse von außen her von besonderem Vorteil ist.By arranging a replaceable nozzle, which restricts the outflow through a with the Piston connected pipe is used, both a damping of the opening process of the main valve as well as a dosage of the back pressure achieved in the control function of the valve, with the easy Accessibility of the nozzle from the outside is of particular advantage.
Die Feinregulierung im ersten Drittel der Gesatntdurchflußgröße wird dadurch erreicht, daß der Sitz des Hauptventils konisch ausgebildet und ein Drittel des Hubweges des Hauptventils hoch ist. Dies ermöglicht beim Absperrventil gleichzeitig eine weiche Entlastung des Schließ druckes, was die Regelfunktion erst ermöglicht. .The fine adjustment in the first third of the total flow rate is achieved in that the seat of the main valve is conical and a third the stroke of the main valve is high. At the same time, this enables soft relief for the shut-off valve the closing pressure, which is what makes the control function possible in the first place. .
Weiterhin ist von Vorteil, daß alle zum elektromagnetischen Antrieb gehörigen Teile unter Verwendung eines bekannten kalthärtenden Zweikomponenten-Kunststoffes, der zwecks günstiger Abführung defi Spulenwärme noch mit Quarzsand versetzt sein kann, zu einer homogenen, geschützten Einheit zusammengefügt sind. Dadurch erübrigt sich die Anordnung eines druckfesten Rohrstutzens zwischen Druck- und Spulenraum, die sonst als Kurzschlußwindung wirksam würde. Damit war weiter möglich, für eine reibungsarme Führung" des Magnetankers ein Magnetkernrohr mit durchgehendem Längsschlitz anzuordnen. Die Zeichnung stellt sine Ausführungsmöglichkeit der Erfindung schematisch dar.Another advantage is that all of the electromagnetic Parts belonging to the drive using a well-known cold-curing two-component plastic, which can be mixed with quartz sand for the purpose of better dissipation of the coil heat, are combined to form a homogeneous, protected unit. This makes the arrangement unnecessary a pressure-resistant pipe socket between the pressure and coil space, which otherwise acts as a short-circuit winding would. This also made it possible to use a magnetic core tube for low-friction guidance of the magnet armature to be arranged with a continuous longitudinal slot. The drawing represents its implementation option of the invention schematically.
