Abstract
Description
Die Erfindung betrifft ein frostsicheres Magnetventil, bei dem eine Ausdehnung eines Mediums in einem Medienraum sich nicht zerstörend auf das Ventil auswirkt. Dieses Ventil kann als 2/2 Ventile ausgestaltet sein.The The invention relates to a frost-proof solenoid valve, in which a Expansion of a medium in a media room is not destructive the valve affects. This valve can be configured as 2/2 valves be.
Seit Jahrzehnten sind diverse Absperrhähne bzw. Ventile für Medienleitungen, insbesondere zur Leitung flüssiger Medien, bekannt.since Decades, various shut-off valves and valves for media lines, in particular for the management of liquid Media, known.
Aus
Es ist bekannt, dass sich beim Gefrieren eines Mediums im Ventil eine temperaturabhängige Volumenänderung von ca. 10% einstellen kann.It It is known that when freezing a medium in the valve a temperature-dependent volume change of about 10%.
Der Nachteil aller voran stehenden Absperrvorrichtungen ist, dass sie nicht frostsicher sind.Of the Disadvantage of all upstream shut-off devices is that they not frost-proof.

Die
Der Erfindung liegt daher die Aufgabe zu Grunde, ein frostsicheres Magnetventil zu schaffen, bei dem eine Ausdehnung eines Mediums in einem Medienraum sich nicht zerstörend auf das Ventil auswirkt und das auch unter extremen Temperatur- und Druckbelastungen haltbar ist und ohne Leckagen arbeitet.Of the The invention is therefore based on the object, a frost-proof solenoid valve to create an expansion of a medium in a media room not destructive affects the valve and that even under extreme temperature and pressure loads is durable and works without leaks.
Zusätzliche Anforderungen an das erfindungsgemäße Magnetventil bestehen in der Integration
- – der Regelfunktion
- – der Medienbeständigkeit der Werkstoffe
- – einer hohen Lebensdauer.
- - the control function
- - the media resistance of the materials
- - a long life.
Gemäß der Erfindung wird diese Aufgabe durch die Merkmale des ersten Patentanspruchs gelöst und durch die Merkmale der Unteransprüche vorteilhaft ausgestaltet.According to the invention This object is achieved by the features of the first claim solved and advantageously designed by the features of the subclaims.
Die erfindungsgemäße Lösung besteht in einer Medientrennung des Ankerraums vom Medienraum durch einen Faltenbalg. Das hat zur Folge, dass der Anker- und Medienraum vor Frostkräften, allgemein vor Ausdehnungskräften geschützt wird, wobei der Faltenbalg so ausgeführt ist, dass er die Dehnung von gefrierenden bzw. gefrorenem Fluid aufnehmen kann. Gleichzeitig können die medienführenden Wandungen des Medienraums auch als Faltenbalg bzw. flexible Gummimembranen ausgeführt sein, so dass auch diese Wandungen nachgiebig gestaltet sind. Durch diese Gestaltung wird die Funktionsfähigkeit des Magnetventils auch bei sich im Medienraum ändernden Druckverhältnissen nicht beeinträchtigt. Insbesondere wird das erfindungsgemäße Ventil weder beschädigt noch wird der Stößel von seinem Dichtsitz abgehoben.The inventive solution exists in a media separation of the anchor space from the media space by a Bellows. As a result, the anchor and media room in front Frost forces, general before expansion forces protected is, wherein the bellows is designed so that it elongation of freezing or frozen fluid can absorb. simultaneously can the media-leading ones Walls of the media room also as bellows or flexible rubber membranes accomplished be so that even these walls are designed compliant. By This design will improve the functionality of the solenoid valve as well changing in the media room pressures not impaired. In particular, the valve according to the invention is neither damaged nor becomes the plunger of lifted off his seat.

Es versteht sich von selbst, dass der verstellbaren Lagerung des Ankers und Stößels Blatt- oder Schraubenfedern dienen können.It It goes without saying that the adjustable mounting of the anchor and pestle leaf or coil springs can serve.
Das den Medienraum umschließende Material muss gegen Korrosionen, die durch die Medien (bspw. Harnstofflösung) hervorgerufen werden können, beständig sein.The enclosing the media room Material must be resistant to corrosion caused by the media (eg urea solution) can be resistant be.
Ein großer Vorteil des erfindungsgemäßen Magnetventils besteht gegenüber dem Stand der Technik darin, dass es auch unter Druckbelastung frostsicher ist.One greater Advantage of the solenoid valve according to the invention exists opposite The prior art in that it is frost resistant even under pressure is.
