Abstract

The valve for the bleeding of a radiator which can be opened or closed by the exertion of pressure on a press button (2) has a fixed part (11) and a movable part (4). A compression spring (8) is fitted in the valve housing (1), and the press button with the ventilation passage (3) in the closed valve position (5) disappears partially or completely in the valve housing, and in the open sate protrudes from it. The fixed part of the pressure mechanism is prevented from being withdrawn by a locking ring.

Description

Bei der Warmwasserheizungsanlage müssen die Heizkörper mit einem Entlüftungsventil ausgestattet werden, damit bei der Befüllung der Anlage die Heizkörper entlüftet werden können. Des Öfteren müssen einzelne Heizkörper vor und während der Heizperiode entlüftet werden. In der Regel sind die Entlüftungsventile mit einem Vierkant versehen, an dem man mittels eines kleinen Schlüssels diese auf- oder zudrehen kann. Der Nachteil liegt darin, dass der kleine Schlüssel oft verloren geht, oder man nicht mehr weiß, wo man ihn abgelegt hat.In the hot water heating system, the radiators must be equipped with a vent valve, so that when filling the system, the radiator can be vented. Often, individual radiators must be vented before and during the heating season. In general, the vent valves are provided with a square on which you can by means of a small key these open or close. The disadvantage is that the small key is often lost, or you no longer know where you put it.

Aufgabe der Erfindung ist es, ein Entlüftungsventil zu konstruieren, bei dem keine Werkzeuge für das Zu- oder Aufdrehen erforderlich sind.The object of the invention is to construct a vent valve, in which no tools for screwing or unscrewing are required.

Aus der Patentschrift Nr. DE 3328553 Q ist ein Entleerungsventil bekannt, bei dem mittels eines Schlauches ein Hohlzylinder aus einem Ventilgehäuse zum Entleeren eines Heizkörpers herausgezogen wird. Der Hohlzylinder ist in einer am Boden geschlossenen Kapsel gelagert. Im geschlossenen Zustand befinden sich die auf dem Hohlzylinder angebrachten Dichtringe vor und hinter den Durchlässen in der Kapsel. Im geöffneten Zustand ist der Hohlzylinder mittels eines Schlauches herausgezogen, so dass die beiden Dichtringe sich vor den Durchlässen in der Kapsel befinden und somit den Weg für das Wasser frei geben.From the patent specification no. DE 3328553 Q a drain valve is known in which by means of a hose, a hollow cylinder is pulled out of a valve housing for emptying a radiator. The hollow cylinder is mounted in a capsule closed at the bottom. When closed, the sealing rings mounted on the hollow cylinder are located in front of and behind the passages in the capsule. In the open state, the hollow cylinder is pulled out by means of a hose, so that the two sealing rings are located in front of the passages in the capsule and thus clear the way for the water.

Dieses Prinzip kommt zur Anwendung, jedoch ist das Öffnen, bzw. Schließen mittels eines Schlauches keine Lösung für einen Entlüftungsstopfen.This principle is used, but the opening or closing by means of a hose is not a solution for a vent plug.

Die Erfindung liegt darin, dass das Entlüftungsventil (1) sich mit einer Druckausübung auf eine Drucktaste (2) öffnen oder schließen lässt und dass die Drucktaste (2) im geöffneten Zustand mit seinem Entlüftungskanal (3) aus dem Ventilgehäuse (1) herausragt. Dies ist dadurch möglich, dass der Drucktaste (2) das bewegliche Teil (4) des Druckmechanismus angeformt ist und dass an ihm der Hohlzylinder (5) mit den beiden axial angebrachten Dichtringen (6) angeordnet ist, der in einer am Boden geschlossenen Kapsel (7), die bis in den vergrößerten Hohlraum des Ventilgehäuses (1) hineinragt, gelagert ist. Die Zylinderaufnahmekapsel (7) dient gleichzeitig für die Führung der 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 Druckmechanismus untergebracht. Die Buchseninnenwandung dient als Führung für den beweglichen Teil (4) des Druckmechanismus, in dem der Rückhaltehaken (12) des feststehenden Teiles (11) eingehakt ist und der den Hohlzylinder (5) in der geschlossenen Stellung hält, wobei die Durchlässe (13) in der Kapsel sich zwischen den beiden Dichtringen (6) befinden.The invention resides in the fact that the venting valve (1) can be opened or closed by applying pressure to a pushbutton (2) and that the pushbutton (2) projects out of the valve housing (1) with its venting duct (3) in the opened state. This is possible because the push button (2), the movable part (4) of the pressure mechanism is formed and that on him the hollow cylinder (5) with the two axially mounted sealing rings (6) is arranged in a closed at the bottom capsule ( 7), which projects into the enlarged cavity of the valve housing (1) is mounted. The cylinder receiving capsule (7) also serves to guide the compression spring (8). Axially 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 printing mechanism is housed. The sleeve inner wall serves as a guide for the movable part (4) of the pressure mechanism in which the retaining hook (12) of the fixed part (11) is hooked and which holds the hollow cylinder (5) in the closed position, the passages (13) in the capsule are between the two sealing rings (6).

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

Eine einfache und preiswertere Lösung ist es, dem Hohlzylinder (5) eine zylindrische Abdeckkappe (14) mit einem Entlüftungskanal (3) anzuformen, der jedoch ganz im Ventilgehäuse (1) verschwindet und an dem wiederum eine Ausziehvorrichtung (15) angebracht ist, mit der man die Abdeckkappe (14) mit dem Entlüftungskanal (3) und dem Hohlzylinder (5) so weit herausziehen kann, bis die beiden Dichtringe (6) neben den Durchlässen (13) positioniert sind und den Weg frei geben. Nach dem Entlüftungsvorgang wird mittels der Ausziehvorrichtung (15) die Abdeckkappe (14) mit dem Entlüftungskanal (3) in das Ventilgehäuse (1) eingedrückt, so dass die Durchlässe (13) verschlossen sind. In diesem Fall kann die Druckfeder (8) und auch der Druckmechanismus eingespart werden.A simple and cheaper solution is to form the hollow cylinder (5) a cylindrical cap (14) with a vent channel (3), but disappears completely in the valve housing (1) and to which in turn a puller (15) is mounted with the You can pull the cap (14) with the vent channel (3) and the hollow cylinder (5) so far until the two sealing rings (6) are positioned next to the passages (13) and clear the way. After the venting operation, the cap (14) with the venting channel (3) is pressed into the valve housing (1) by means of the extraction device (15), so that the passages (13) are closed. In this case, the compression spring (8) and also the printing mechanism can be saved.

Die Dichtringe (6) sind auf dem Hohlzylinder (5) an beiden Varianten so angeordnet, dass die Drucktaste (2) oder die Abdeckkappe (14) mit ihrem Entlüftungskanal (3) weit genug herausgedrückt bzw. herausgezogen sind, bis sich das Ventil erst öffnet. Bei vergrößertem Durchmesser des Entlüftungskanals (3) können die beiden Varianten auch als Entleerungsventile genutzt werden.The sealing rings (6) are arranged on the hollow cylinder (5) on both variants so that the push-button (2) or the cap (14) with their venting channel (3) pushed far enough or pulled out until the valve opens first. With an enlarged diameter of the ventilation channel (3), the two variants can also be used as drain valves.
