Description

Die Erfindung betrifft ein Ventil zum Entlüften eines Heizkörpers.The invention relates to a valve for venting a radiator.

Heizkörper von Warmwasserheizungsanlagen sind in aller Regel mit einem Entlüftungsventil ausgestattet. Eine Entlüftung einzelner Heizkörper ist bei der Befüllung der Anlage und ggf. vor und während der Heizperiode notwendig. Die Entlüftungsventile sind heute normalerweise mit einem Vierkant versehen, an dem man sie mit einem kleinen Schlüssel auf- oder zudrehen kann. Nachteilig ist, dass der Schlüssel oft verloren geht oder verlegt wird.Radiators of hot water heating systems are usually equipped with a vent valve. Ventilation of individual radiators is necessary when filling the system and if necessary before and during the heating period. The vent valves today are usually provided with a square, on which you can open or close them with a small key. The disadvantage is that the key is often lost or misplaced.

Die DE 203 03 986 U1 offenbart ein Entlüftungsventil für Heizkörper mit einem in einer Öffnung des Heizkörpers anbringbaren Haltekörper und mit einem an diesem Haltekörper axial verstellbaren Ventilkörper, der in Ausgangslage einen Entlüftungsdurchgang oder Entlüftungskanal verschließt und nach axialer Verstellung freigibt, wobei der Entlüftungskanal in dem Ventilkörper selbst angeordnet ist und der Ventilkörper axial gegen eine Rückstellkraft an einer Betätigungsfläche zum Öffnen des Ventils in den Haltekörper einschiebbar ist. Zur Erzeugung der Rückstellkraft zwischen Haltekörper und Ventilkörper ist das Entlüftungsventil mit einer Rückstellfeder versehen. Nachteilig ist hier, dass man die am Ende des Entlüftens austretende Flüssigkeit nur mit einem Lappen o.ä. auffangen kann.The DE 203 03 986 U1 discloses a vent valve for radiators with an attachable in an opening of the radiator holding body and with a holding body axially adjustable valve body which closes in the initial position a vent passage or vent passage and releases after axial adjustment, wherein the vent channel is disposed in the valve body itself and the valve body axially against a restoring force on an actuating surface for opening the valve in the holding body can be inserted. To generate the restoring force between the holding body and valve body, the vent valve is provided with a return spring. The disadvantage here is that you o.ä the liquid exiting at the end of the venting with a rag. can catch.

Aus der DE 33 28 553 A1 ist ein Ventil zum Befüllen oder Entleerung eines Heizkörpers bekannt, das ein Ventilgehäuse, das aus einer zylindrischen, am Ende geschlossenen Kapsel mit radialem Durchlass gebildet ist, und einen bewegbaren, aus einem Hohlzylinder mit zwei in Abstand voneinander auf seinem Umfang angeordneten Dichtringen gebildeten Verschlusskörper aufweist, der starr mit einem Anschlussstutzen verbunden ist. In der Schließstellung des Verschlusskörpers liegt der radiale Durchlass zwischen den beiden Dichtringen und in der Offenstellung hinter dem hinteren Dichtring. Der Anschlussstutzen kann zum Herausziehen mit einer Kupplungsmuffe oder auch nur einem Stück Schlauch gefasst werden.From the DE 33 28 553 A1 a valve for filling or emptying a radiator is known, which is a valve housing, which is formed from a cylindrical, closed-end capsule with radial passage, and a movable, of a hollow cylinder with two spaced apart on its circumference sealing rings having formed closure body which is rigidly connected to a connecting piece. In the closed position of the closure body is the radial passage between the two sealing rings and in the open position behind the rear sealing ring. The connecting piece can be pulled out with a coupling sleeve or just a piece of hose to be pulled out.

Aufgabe der Erfindung ist es, ein Entlüftungsventil zu schaffen, bei dem keine Werkzeuge für das Schließen oder Öffnen erforderlich sind und das einfach zu bedienen ist.The object of the invention is to provide a vent valve in which no tools for closing or opening are required and which is easy to use.

Die Aufgabe wird durch ein Ventil zum Entlüften eines Heizkörpers mit einem Ventilgehäuse gelöst, in dem ein feststehender Teil eines Mechanismus zum Öffnen und Schließen des Ventils untergebracht ist und in dem ein beweglicher Teil des Mechanismus zwischen einer Offenstellung und einer Schließstellung verschiebbar gelagert ist, wobei der bewegliche Teil einen als Hohlzylinder ausgebildeten Verschlusskörper sowie einen Zug-/Schiebegriff oder eine Drucktaste, die in der Schließstellung des beweglichen Teils wenigstens teilweise im Ventilgehäuse verschwindet und die durch eine im Ventilgehäuse angeordnete Druckfeder in die Offenstellung verschiebbar ist, umfasst und einen Entlüftungskanal aufweist, wobei die Drucktaste oder der Zug-/Schiebegriff in der Offenstellung des beweglichen Teils weiter aus dem Ventilgehäuse herausragt als in der Schließstellung und der feststehende Teil des Mechanismus einen in der Schließstellung einrastenden sowie in der Offenstellung am beweglichen Teil einhakenden Rückhaltehaken umfasst.The object is achieved by a valve for venting a radiator with a valve housing in which a fixed part of a mechanism for opening and closing the valve is housed and in which a movable part of the mechanism is slidably mounted between an open position and a closed position, wherein movable part designed as a hollow cylinder closure body and a pull / push handle or a pushbutton, which disappears in the closed position of the movable part at least partially in the valve housing and which is displaceable by a valve disposed in the pressure housing spring in the open position, comprises and has a vent channel, wherein the push button or the push / pull handle in the open position of the movable part further protrudes from the valve housing than in the closed position and the fixed part of the mechanism a latching in the closed position and in the open position on bewegli includes a part hooking retaining hooks.

Das Ventil kann somit in geöffneter oder geschlossener Stellung eingehakt oder eingerastet werden. Der bewegliche Teil wird mittels der Drucktaste oder dem Zug-/Schiebegriff in die jeweilige Stellung gebracht und durch Einrasten des Rückhaltehakens arretiert. Da der Verschlusskörper mit der Drucktaste oder dem Zug-/Schiebegriff in geöffneter Stellung aus dem Ventilgehäuse herausragt, kann man die am Ende des Entlüftungsvorganges austretende Flüssigkeit leicht in einem Gefäß auffangen.The valve can thus be hooked or engaged in the open or closed position. The movable part is brought by means of the push button or the pull / push handle in the respective position and locked by locking the retaining hook. Since the closure body protrudes with the pushbutton or the pull / push handle in the open position out of the valve housing, it is easy to catch the liquid emerging at the end of the deaeration process in a vessel.

In einer Weiterbildung der Erfindung ist der Rückhaltehaken durch kurzes Eindrücken der Drucktaste aus seiner Raststellung am beweglichen Teil lösbar und das Ventil lässt sich öffnen.In a further development of the invention, the retaining hook can be released by briefly pressing the pushbutton out of its rest position on the movable part and the valve can be opened.

In einer Ausgestaltung der Erfindung verläuft der Entlüftungskanal durch die Drucktaste und die Austrittsöffnung des Entlüftungskanals und ist vorzugsweise auf dem Rand der Drucktaste angeordnet.In one embodiment of the invention, the venting channel extends through the pushbutton and the outlet opening of the venting channel and is preferably arranged on the edge of the pushbutton.

In einer anderen Ausgestaltung der Erfindung weist der Verschlusskörper eine zylindrische Abdeckkappe auf und der Entlüftungskanal ist durch die Abdeckkappe nach außen geführt, wobei die entsprechende Austrittsöffnung vorzugsweise auf dem Rand der Abdeckkappe angeordnet ist.In another embodiment of the invention, the closure body has a cylindrical cap and the vent channel is guided through the cap to the outside, wherein the corresponding outlet opening is preferably arranged on the edge of the cap.

Zweckmäßigerweise ist der feststehende Teil des Mechanismus gegen Herausziehen durch einen Sprengring gesichert.Conveniently, the fixed part of the mechanism is secured against being pulled out by a snap ring.

In einer weiteren Ausgestaltung der Erfindung ist das Ventilgehäuse mit einer rohrförmigen Aufnahmekapsel für den Verschlusskörper mit einem im Verhältnis zum Innendruckmesser des restlichen Ventilgehäuse geringeren Durchmessers versehen, wobei die Aufnahmekapsel vorzugsweise zumindest teilweise in den Teil des Ventilgehäuses mit dem größeren Durchmesser hineinragt und eine Führung für die Druckfeder und den Verschlusskörper bildet.In a further embodiment of the invention, the valve housing is provided with a tubular receiving capsule for the closure body with a relation to the internal pressure gauge of the remaining valve housing of smaller diameter, the receiving capsule preferably at least partially protrudes into the part of the valve housing with the larger diameter and a guide for the Compression spring and the closure body forms.

Zweckmäßigerweise sind auf dem Verschlusskörper zwei Dichtringe derart angeordnet, dass die Drucktaste bzw. die Abdeckkappe so weit aus dem Ventilgehäuse herausgedrückt bzw. gezogen sind, dass sich die Austrittsöffnung des Entlüftungskanals außerhalb des Ventilgehäuses befindet.Conveniently, two sealing rings are arranged on the closure body such that the pushbutton or the cap are so far pushed out or pulled out of the valve housing, that the outlet opening of the venting channel is outside of the valve housing.

In einer anderen Ausgestaltung ist die Zylinderaufnahmekapsel mit Durchlässen versehen und auf dem Verschlusskörper sind zwei Dichtringe in einem derartigen Abstand voneinander angeordnet, dass die Durchlässe in der Schließstellung zwischen dem Dichtring und in der Offenstellung vor den Dichtringen liegen.In another embodiment, the cylinder receiving capsule is provided with passages and on the closure body, two sealing rings are arranged at a distance from each other such that the passages are in the closed position between the sealing ring and in the open position in front of the sealing rings.

Die genannten Ventile können auch als Entleerungsventile genutzt werden.The valves mentioned can also be used as drain valves.

Fig. 1 zeigt eine an einem beweglichen Teil 4 des Mechanismus angeformte Drucktaste 2. Der bewegliche Teil 4 weist einen Hohlzylinder 5 auf, an dem zwei Dichtringe 6 axial angeordnet sind und der in einer am Boden geschlossenen zylindrischen Aufnahmekapsel 7, die bis in den vergrößerten Hohlraum des Ventilgehäuses 1 hineinragt, gelagert ist. Die Aufnahmekapsel 7 dient gleichzeitig zur Führung einer Druckfeder 8. Axial zwischen der Druckfeder 8 und der Wandung des Ventilgehäuses ist eine Buchse 9, die durch einen Sprengring 10 gesichert ist, gelagert. In der Buchsenwandung 9 ist der feststehende Teil 11 des Mechanismus untergebracht. Die Buchseninnenwandung dient als Führung für den beweglichen Teil 4 des Mechanismus, indem der Rückhaltehaken 12 des feststehenden Teils 11 eingehakt ist und der den Hohlzylinder 5 in der geschlossenen Stellung hält, wobei sich die Durchlässe in der Kapsel zwischen den beiden Dichtringen befinden. Das Entlüftungsventil 1 lässt mit einer Druckausübung auf die Drucktaste öffnen oder schließen. Die Drucktaste ragt im geöffneten Zustand mit einem Entlüftungskanal aus dem Ventilgehäuse heraus. Fig. 1 shows a molded on a movable part 4 of the mechanism push button 2. The movable part 4 has a hollow cylinder 5, on which two sealing rings 6 are arranged axially and in a closed at the bottom cylindrical receiving capsule 7, which extends into the enlarged cavity of the valve housing 1 protrudes, is stored. Axial between the compression spring 8 and the wall of the valve housing is a bushing 9 which is secured by a snap ring 10, stored. In the Buchsenwandung 9 of the fixed part 11 of the mechanism is housed. The bushing inner wall serves as a guide for the movable part 4 of the mechanism by hooking the retaining hook 12 of the fixed part 11 and holding the hollow cylinder 5 in the closed position, the passages being in the capsule between the two sealing rings. The vent valve 1 can be opened or closed with a pressure on the push button. The push button protrudes in the open state with a vent channel out of the valve housing.

Zum Entlüften des Heizkörpers wird durch kurzes Eindrücken der Drucktaste der Rückhaltehaken aus der geschlossenen Stellung gelöst, so dass die Druckfeder 8 die Drucktaste 2 mit dem Entlüftungskanal 3 und mit ihr der Hohlzylinder 5 aus dem Ventilgehäuse 1 herausdrückt. Die beiden Dichtringe 6 sind dann vor den Durchlässen 13 der Kapsel positioniert und der Weg ist für die ausströmende Luft frei. Der Rückhaltehaken 12 hakt in der geöffneten Stellung ein. Ist der Entlüftungsvorgang beendet, wird der Hohlzylinder durch Betätigung der Drucktaste 2 wieder in das Ventilgehäuse 1 gedrückt, der Rückhaltehaken rastet nun bei geschlossener Stellung des Ventils ein.To vent the radiator is released by briefly pressing the push button of the retaining hook from the closed position, so that the compression spring 8 pushes the push button 2 with the vent channel 3 and with it the hollow cylinder 5 from the valve housing 1. The two sealing rings 6 are then positioned in front of the passages 13 of the capsule and the path is free for the outflowing air. The retaining hook 12 hooks in the open position. If the venting process is completed, the hollow cylinder is pressed by pressing the push button 2 back into the valve housing 1, the retaining hook now locks in the closed position of the valve.

In einer anderen Ausführungsform ist am Hohlzylinder 5 eine zylindrische Abdeckkappe 14 mit einem Entlüftungskanal 3 angeformt, der in Schließstellung ganz im Ventilgehäuse 1 verschwindet und an dem ein Zug-/Schiebegriff 15 angebracht ist, mit der man die Abdeckkappe 14 mit dem Entlüftungskanal 3 und dem Hohlzylinder 5 soweit herausziehen kann, bis die beiden Dichtringe 6 neben den Durchlässen 13 positioniert sind und den Weg für die Luft freigeben. Nach dem Entlüftungsvorgang wird mittels des Zug-/Schiebegriffs 15 die Abdeckkappe 14 mit dem Entlüftungskanal 3 in das Ventilgehäuse 1 eingeschoben, so dass die Durchlässe 13 verschlossen sind.In another embodiment, a cylindrical cap 14 is integrally formed with a vent channel 3 on the hollow cylinder 5, which disappears in the closed position completely in the valve housing 1 and to which a pull / push handle 15 is attached, with which the cap 14 with the vent channel 3 and the Hollow cylinder 5 can pull out until the two sealing rings 6 are positioned next to the passages 13 and clear the way for the air. After the venting process, the cap 14 is inserted with the vent channel 3 into the valve housing 1 by means of the pull / push handle 15, so that the passages 13 are closed.

Die Dichtringe 6 sind in beiden Varianten so auf dem Hohlzylinder 5 angeordnet, dass die Drucktaste 2 oder die Abdeckkappe 14 mit ihrem Entlüftungskanal 3 so weit aus dem Ventilgehäuse 1 herausgedrückt bzw. herausgezogen sind, dass sich die Austrittsöffnung des Entlüftungskanals 3 außerhalb des Ventilgehäuses 1 befindet, wenn sich das Ventil öffnet. Bei vergrößertem Durchmesser des Entlüftungskanals 3 können die beiden Varianten auch als Entleerungsventile genutzt werden.The sealing rings 6 are arranged in both variants on the hollow cylinder 5, that the push button 2 or the cover 14 so far pushed out with its vent channel 3 from the valve body 1 or pulled out that the outlet opening of the vent channel 3 is outside of the valve housing 1 when the valve opens. With an enlarged diameter of the venting channel 3, the two variants can also be used as drain valves.
