Description

Die gegenständliche Erfindung betrifft eine Überlauf-Armatur für ein Sicherheitsventil bestehend aus einem mit einem Ablaufrohr ausgebildeten becherartigen Gefäß, welches mit einem trichterartigen Einsatz und mit einem Geruchsverschluß in Form eines den trichterartigen Einsatz umgebenden und an seinem unteren Ende geschlossenen Rohres versehen ist, wobei der obere Rand des trichterartigen Einsatzes am oberen Rand des becherartigen Gefäßes befestigt ist.The subject invention relates to an overflow fitting for a safety valve consisting of a cup-like vessel formed with a drain pipe, which is provided with a funnel-like insert and with an odor trap in the form of a pipe surrounding the funnel-like insert and closed at its lower end, the upper one Edge of the funnel-like insert is attached to the upper edge of the cup-like vessel.

Derartige Überlauf-Armaturen, welche unterhalb von Sicherheitsventilen für Heißwasserspeicher angeordnet werden, dienen dazu, im Falle, daß das Sicherheitsventil auslöst, das aus diesem ausströmende Wasser aufzunehmen.Such overflow fittings, which are arranged below safety valves for hot water storage, are used in the event that the safety valve triggers to absorb the water flowing out of it.

Bei bekannten derartigen Überlauf-Armaturen ist der trichterartige Einsatz rotationssymmetrisch ausgebildet und ist er mit dem becherartigen Überlaufgefäß fest verbunden. Bei der Montage einer derartigen Armatur besteht jedoch das Problem, daß sich das in der Wand für die Montage der Überlauf-Armatur vorgesehene Anschlußrohr nicht immer genau lotrecht unterhalb des Sicherheitsventiles befindet, sondern gegenüber diesem seitlich versetzt ist. Dies hat zur Folge, daß sich der Trichterstutzen der Überlauf-Armatur nicht genau unterhalb des Auslaufrohres des Sicherheitsventiles befindet. Unter Berücksichtigung des Sachverhaltes, daß bei einem Auslösen des Sicherheitsventiles aus diesem ein unter hohem Druck stehender Wasserstrahl austritt, hat dies zur Folge, daß Spritzwasser bedingt wird. Um dies zu vermeiden, ist es bekannt, die Überlauf-Armatur geringfügig zu verdrehen, wodurch sich zwar der Einlauftrichter mittig unterhalb des Auslaufrohres des Sicherheitsventils befindet. Da jedoch dann der an den Einlauftrichter anschließende Trichterstutzen nicht lotrecht ausgerichtet ist, wird auch dabei dann, sobald das Sicherheitsventil auslöst, Spritzwasser verursacht.In known overflow fittings of this type, the funnel-like insert is rotationally symmetrical and is firmly connected to the cup-like overflow vessel. When assembling such a valve, however, there is the problem that the connecting pipe provided in the wall for the assembly of the overflow valve is not always exactly perpendicular below the safety valve, but is laterally offset with respect to it. The consequence of this is that the funnel connection of the overflow fitting is not exactly below the outlet pipe of the safety valve. Taking into account the fact that when the safety valve is triggered, a high-pressure water jet emerges from it, this has the consequence that splash water is caused. In order to avoid this, it is known to twist the overflow fitting slightly, as a result of which the inlet funnel is located centrally below the outlet pipe of the safety valve. However, since the funnel connection adjoining the inlet funnel is then not aligned vertically, splash water is also caused as soon as the safety valve triggers.

Der gegenständlichen Erfindung liegt demnach die Aufgabe zugrunde, eine Überlauf-Armatur für Sicherheitsventile zu schaffen, durch welche auch dann, wenn die einander zugeordneten Anschlußrohre für das Sicherheitsventil und für die Überlauf-Armatur nicht exakt zueinander ausgerichtet sind, in einfacher Weise eine Einstellung der Überlauf-Armatur dahingehend vorgenommen werden kann, daß sich der Trichterstutzen des Überlaufgefäßes lotrecht unterhalb des Auslaßrohres des heitsventiles befindet.The object of the invention is therefore to provide an overflow fitting for safety valves, through which even if the associated connecting pipes for the safety valve and for the overflow fitting are not exactly aligned with one another, the overflow can be adjusted in a simple manner Fitting can be made in such a way that the funnel neck of the overflow vessel is located vertically below the outlet pipe of the safety valve.

Dies wird erfindungsgemäß dadurch erzielt, daß die Achse des Trichterstutzens gegenüber dem oberen Rand des Einsatzes exzentrisch angeordnet ist und daß der trichterartige Einsatz gegenüber dem becherartigen Gefäß verdrehbar ist. Vorzugsweise ist der trichterartige Einsatz an seinem oberen Rand mit einem nach unten abragenden zylindrischen Ansatz, welcher an der Innenwand des becherartigen Gefäßes zur Anlage kommt, und mit einer ringförmigen Anschlagfläche, welche an den oberen Rand des becherartigen Gefäßes zur Anlage kommt, ausgebildet. Die Exzentrizität der Mittelachse des Trichterstutzens beträgt vorzugsweise 5 mm bis 15 mm, insbesondere 10 mm.This is achieved according to the invention in that the axis of the funnel neck is arranged eccentrically with respect to the upper edge of the insert and in that the funnel-like insert is rotatable relative to the cup-like vessel. Preferably, the funnel-like insert is formed at its upper edge with a downwardly projecting cylindrical projection, which comes to rest on the inner wall of the cup-like vessel, and with an annular stop surface, which comes to rest on the upper edge of the cup-like vessel. The eccentricity of the central axis of the funnel nozzle is preferably 5 mm to 15 mm, in particular 10 mm.

Fig. 3
this overflow fitting, in top view.

Eine erfindungsgemäße Überlauf-Armatur besteht aus einem becherartigen Gefäß 1, welches mit einem Abflußrohr 11 ausgebildet ist. Mittels dieses Ablaufrohres 11 ist das becherartige Gefäß 1 an ein in einer Wand befindliches Ablaufrohr anschließbar.An overflow fitting according to the invention consists of a cup-like vessel 1, which is formed with a drain pipe 11. By means of this drain pipe 11, this is cup-like Vessel 1 can be connected to a drain pipe located in a wall.

Das becherartige Gefäß 1 ist weiters mit einem trichterartigen Einsatz 2 ausgebildet, welcher von einem als Geruchsverschluß dienenden, an seiner Unterseite abgeschlossenen Rohrstück 3 umgeben ist. Der trichterartige Einsatz 2 ist an seinem oberen Rand mit einem zylindrischen Ansatz 21 ausgebildet, welche an die Innenwand des becherartigen Gefäßes 1 anliegt. Der Einsatz 21 ist weiters mit einer ringförmigen Anschlagfläche 22 ausgebildet, welche der oberen Stirnfläche 12 des becherartigen Gefäßes 1 gegenüberliegt. Weiters ist der Trichterstutzen 23 gegenüber dem zylindrischen Ansatz 22 exzentrisch angeordnet. Da der trichterförmige Einsatz 2 mit dem becherartigen Gefäß 1 nicht starr verbunden ist, ist er gegenüber diesem verdrehbar. Das Rohrstück 3 ist am Trichterstutzen 23 mittels Stegen 31 befestigt.The cup-like vessel 1 is also formed with a funnel-like insert 2, which is surrounded by a tube piece 3, which serves as an odor trap and is closed on its underside. The funnel-like insert 2 is formed at its upper edge with a cylindrical projection 21 which bears against the inner wall of the cup-like vessel 1. The insert 21 is also formed with an annular stop surface 22 which lies opposite the upper end surface 12 of the cup-like vessel 1. Furthermore, the funnel nozzle 23 is arranged eccentrically with respect to the cylindrical extension 22. Since the funnel-shaped insert 2 is not rigidly connected to the cup-like vessel 1, it can be rotated relative to the latter. The pipe section 3 is fastened to the funnel connection 23 by means of webs 31.

Soferne ein einem Heißwasserspeicher zugeordnetes Überdruckventil öffnet, wodurch aus dessen Auslaufrohr 4 Wasser ausströmt, gelangt ein Wasserstrahl 5 durch den trichterartigen Einsatz 2 in das becherartige Gefäß 1, und strömt durch den Trichterstutzen 23 nach unten bzw. zwischen dem Trichterstutzen 23 und dem Rohrstück 3, wie dies in Fig. 2 durch Pfeile angedeutet ist, nach oben in das becherartige Gefäß 1 und schließlich durch das Rohrstück 11 hindurch ab. Hierdurch wird ein Geruchsverschluß bewirkt.If a pressure relief valve assigned to a hot water tank opens, causing water to flow out of its outlet pipe 4, a water jet 5 passes through the funnel-like insert 2 into the cup-like vessel 1 and flows down through the funnel nozzle 23 or between the funnel nozzle 23 and the pipe piece 3, as indicated by arrows in FIG. 2, upwards into the cup-like vessel 1 and finally through the pipe section 11. This causes an odor trap.

Aufgrund des hohen Druckes, mit welchem der Wasserstrahl 5 in den trichterartigen Einsatz 2 gelangt, muß sich zur Vermeidung von Spritzwasser der Trichterstutzen 23 genau unterhalb des Auslaufrohres 4 befinden. Um diese genaue Austrichtung des Trichterstutzens 23 gegenüber dem Auslaufrohr 4 zu ermöglichen, ist der Trichterstutzen 23 am trichterartigen Einsatz 2 exzentrisch angeordnet. Hierdurch kann durch Verdrehung des Einsatzes 2 der Trichterstutzen 23 quer zum Rohrstück 11 im Ausmaß der doppelten Exzentrizität verstellt werden, wodurch Ungenauigkeiten in der seitlichen Anordnung des Auslaßrohres 4 gegenüber dem wandseitigen Anschluß für das Abflußrohr ausgeglichen werden können. Der Abstand zum Abflußrohr kann durch die Länge des Rohrstückes 11 gewählt werden.Due to the high pressure with which the water jet 5 enters the funnel-like insert 2, the funnel nozzle 23 must be located exactly below the outlet pipe 4 to avoid splashing water. In order to enable this precise alignment of the funnel nozzle 23 with respect to the outlet pipe 4, the funnel nozzle 23 is arranged eccentrically on the funnel-like insert 2. As a result, by twisting the insert 2, the funnel connection piece 23 can extend transversely to the pipe section 11 the double eccentricity can be adjusted, whereby inaccuracies in the lateral arrangement of the outlet pipe 4 compared to the wall-side connection for the drain pipe can be compensated. The distance to the drain pipe can be chosen by the length of the pipe section 11.

Bei einem Ausführungsbeispiel wurde die Exzentrizität des Trichterstutzens 23 mit 10 mm gewählt, wodurch seitliche Abweichungen des Anschlusses an das Abflußrohr gegenüber dem Sicherheitsventil bis zu 20 mm ausgeglichen werden können, ohne daß hierdurch Nachteile bedingt werden.In one embodiment, the eccentricity of the funnel nozzle 23 was chosen to be 10 mm, as a result of which lateral deviations in the connection to the drain pipe compared to the safety valve can be compensated for by up to 20 mm, without any disadvantages being caused thereby.
