Abstract
Description
Die vorliegende Erfindung betrifft ein Kippventil gemäß dem Oberbegriff des Anspruchs 1 zum Austragen von Schaum und anderen Medien. Eingesetzt werden diese Ventile insbesondere zum Austragen von PU-Schaum, aber auch im Nahrungsmittelbereich.The present invention relates to a tilt valve according to the preamble of claim 1 for discharging foam and other media. These valves are used in particular for the discharge of PU foam, but also in the food industry.
Die bekannten Kippventile besitzen einen Ventilteller, der mit einem Behälterkörper verkrimpt wird. Ein Ventilkörper mit einer Halteöffnung ist in einer zentralen Öffnung in dem Ventilteller gehalten. Der auch als Formstück bezeichnete Ventilkörper besitzt an einer von dem Ventilteller fortweisenden Seite eine als Ventilsitz dienende Abdichtfläche. Ein Ventilelement ist in der Halteöffnung des Ventilkörpers angeordnet und besitzt einen rohrförmigen Abschnitt mit einem Abdichtflansch an einem Ende und Eintrittsöffnungen in der Rohrwandung nahe dem Abdichtflansch. In der verschlossenen Position des Ventils liegt der Abdichtflansch an der Abdichtfläche an und verhindert den Austritt des auszutragenden Mediums über die Eintrittsöffnungen in den rohrförmigen Abschnitt des Ventilelements. In einer gekippten Position des Ventilelements, bei der ein aus der Halteöffnung vorstehender Ventilstem gegenüber der Längsachse geneigt ist, wird ein Spalt zwischen Abdichtflansch und Abdichtfläche gebildet, durch den ein auszutragendes Medium zu der Eintrittsöffnung gelangt und über diese und den rohrförmigen Abschnitt austritt.The known tilt valves have a valve disk which is crimped with a container body. A valve body with a holding opening is held in a central opening in the valve disk. The valve body, also referred to as a fitting, has a sealing surface serving as a valve seat on a side facing away from the valve disk. A valve element is disposed in the retaining opening of the valve body and has a tubular portion with a sealing flange at one end and inlet openings in the tube wall near the sealing flange. In the closed position of the valve, the sealing flange bears against the sealing surface and prevents the discharge of the medium to be discharged via the inlet openings into the tubular section of the valve element. In a tilted position of the valve element, in which a Ventilstem projecting from the holding opening is inclined relative to the longitudinal axis, a gap between Abdichtflansch and sealing surface is formed, passes through a medium to be discharged to the inlet opening and exits through this and the tubular portion.
Aus
Mit der Verwendung fällt der Druck im Behälterinnenraum und der Massenstrom des ausgetragenen Mediums nimmt mit fallendem Druck ab.With the use of the pressure drops in the container interior and the mass flow of the discharged medium decreases with decreasing pressure.
Der Erfindung liegt die Aufgabe zugrunde, ein Kippventil zu schaffen, das mit einfachen Mitteln einen konstanten Massenstrom aus dem Behälter auch bei fallendem Druck gewährleistet.The invention has for its object to provide a tilt valve, which ensures a simple flow of constant mass flow from the container even with falling pressure.
Erfindungsgemäß wird die Aufgabe durch ein Kippventil mit den Merkmalen aus Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen bilden den Gegenstand der Unteransprüche.According to the invention the object is achieved by a tilting valve with the features of claim 1. Advantageous embodiments form the subject of the dependent claims.
Das erfindungsgemäße Kippventil mit den Merkmalen des Oberbegriffs von Anspruch 1 besitzt zudem einen federnd vorgespannten oder elastischen Sperrkörper, der in dem rohrförmigen Abschnitt des Ventilelements angeordnet ist und abhängig von dem Druck in dem Behälter die Eintrittsöffnung in dem Ventilelement freigibt oder mindestens teilweise verschließt. Hierbei ist es so, daß mit fallendem Druck die Eintrittsöffnung zunehmend freigegeben wird, wodurch bei fallendem Druck die Eintrittsöffnung in den rohrförmigen Abschnitt des Ventilelements sich zunehmend vergrößert.The tilting valve according to the invention with the features of the preamble of claim 1 also has a resiliently biased or elastic locking body which is arranged in the tubular portion of the valve element and depending on the pressure in the container, the inlet opening in the valve element releases or at least partially closes. It is so that with increasing pressure, the inlet opening is increasingly released, whereby with decreasing pressure, the inlet opening in the tubular portion of the valve element increases increasingly.
In einer bevorzugten Ausgestaltung ist der Sperrkörper als ein elastisches Membranelement ausgebildet. Durch den im Behälter herrschenden Druck, wird das elastische Membranelement abhängig von der Stärke des Drucks tiefer in den Austrittskanal gedrückt und verschließt so teilweise die Eintrittsöffnung abhängig von dem Druckwert.In a preferred embodiment, the blocking body is designed as an elastic membrane element. As a result of the pressure prevailing in the container, the elastic membrane element is pressed deeper into the outlet channel depending on the intensity of the pressure and thus partially closes off the inlet opening depending on the pressure value.

Die Kappe sichert den Haltebereich des Membranelements an dem Ventilelement und weist mindestens eine Durchbrechung auf, damit das Membranelement mit dem Innendruck des Behälters beaufschlagt wird. In einer zweckmäßigen Ausgestaltung umgreift die Kappe den Abdichtflansch mindestens teilweise und ist an diesem verrastet.In a preferred embodiment, the valve element has a cap receiving the membrane element. The cap secures the retaining region of the membrane element to the valve element and has at least one opening, so that the membrane element is acted on by the internal pressure of the container. In an expedient embodiment, the cap surrounds the sealing flange at least partially and is latched thereto.
In einer bevorzugten Ausgestaltung ist die Eintrittsöffnung als Langloch ausgebildet, das sich in axialer Richtung des Ventilelements erstreckt. Bei nahezu vollständig ausgetragenem Medium ist die Eintrittsöffnung vollständig freigegeben. Die freigegebene Eintrittsöffnung ermöglicht bei gesunkenem Druck den maximalen Austritt des Mediums. Bei im wesentlichen vollständiger Druckbeaufschlagung des Behälters verschließt das elastische Membranelement die Eintrittsöffnung teilweise.In a preferred embodiment, the inlet opening is formed as a slot which extends in the axial direction of the valve element. With almost completely discharged medium, the inlet opening is completely released. The released inlet opening allows the maximum leakage of the medium when the pressure drops. In substantially complete pressurization of the container, the elastic membrane element partially closes the inlet opening.
Zweckmäßigerweise besitzt das Ventilelement mindestens vier beabstandete Eintrittsöffnungen.Conveniently, the valve element has at least four spaced inlet openings.
