Description
Ringdichtung Die Erfindung betrifft eine Ringdichtung für Rohrverbindungen. Ring seal The invention relates to a ring seal for pipe connections.
Ringdichtungen dienen zur Abdichtung an ruhenden und bewegten Bauteilen. Normalerweise werden zur Erfüllung dieser Erfordernisse Runddichtringe aus elastischem Material verwendet, die in eine entsprechende Nut eingelegt werden. Zur Erzielung technischer Dichtheit ist eine präzise Ausführung der Nuten notwendig. Die präzise Ausführung der Nuten an oberflächengeschützten Auteilen ist schwierig und technisch aufwendig. Außerdem wird an Flanschen durch die Nuten die mechanische Festigkeit verringert, was besonders Kunststoff-Flansche gefährdet. Bei flachen Nuten wird der Anpreßdruck auf den Runddichtring zu hoch und dieser infolge der Fließeigenschaften des Dichtungsmaterials bleibend geschädigt.Ring seals are used to seal stationary and moving components. Normally, to meet these requirements, O-rings are made of elastic Material used, which are inserted into a corresponding groove. To achieve technical tightness, a precise execution of the grooves is necessary. The precise Making the grooves on surface-protected auto parts is difficult and technical laborious. In addition, the grooves increase the mechanical strength of the flanges reduced, which particularly endangers plastic flanges. With shallow grooves the contact pressure on the O-ring is too high and this is due to the flow properties of the sealing material permanently damaged.
Der Erfindung liegt als Aufgabe eine leicht austauschbare Ringdiohtung zugrunde, die eine Flanschkonstruktion ohne Nuten ermöglicht und eine mechanische Uberbeanspruchung des Dichtringes verhindert.The object of the invention is an easily exchangeable ring seal which enables a flange construction without grooves and a mechanical one Overstressing of the sealing ring is prevented.
Die Aufgabe wird erfindungs#mäß gelöst durch einen Runddichtring ( auch O-Ring genannt ) mit angeformtem Distanzring, wobei dessen Dicke kleiner ist, als der Durchmesser des Runddichtringes. Dadurch wird erreicht, daß beim Zusammenbau der Gegenflansch nach der vorgesehenen Verformung des Runddichtringes auf dem Distanzring aufsitzt und eine mechanische Überbeanspruchung des Dichtringmaterials vermieden wird. Zur Erhöhung der Steifigkeit ist der Distanzring vorzugsweise durch eingeformtes Blech oder Gewebe verstärkt.The object is achieved according to the invention by an O-ring ( also called O-ring) with molded spacer ring, whereby its thickness is smaller, than the diameter of the O-ring. This ensures that during assembly the counter flange after the intended deformation of the O-ring on the spacer ring sits and mechanical overstressing of the sealing ring material is avoided will. To increase the rigidity, the spacer ring is preferably molded in Reinforced sheet metal or fabric.
Gemäß einer besonderen Ausführungsform der Erfindung ist die Rundringdichtung mit einem angeformten Haltekragen versehen. Haltekragen bei Dichtungen sind an sich bekannt und bieten den Vorteil, daß die Dichtung in definierter Weise auf den Flansch gesetzt werden kann, so daß sie einwandfrei zentriert ist.According to a particular embodiment of the invention, the O-ring seal provided with a molded retaining collar. Retaining collars in seals are inherent known and offer the advantage that the seal in a defined manner on the flange can be set so that it is properly centered.
Bei einem Einsatz dieser Rundringdichtung gegen Vakuum oder aggressive Medien hat es sich als zweckmäßig erwiesen, einen Stützring einzusetzen. Die Dicke des Stützringes aus einem geeigneten Material, z.B. Polypropylen, Fluorkunststoff oder Keramik soll der Dicke des angeformten Distanzringes entsprechen.When using this O-ring seal against vacuum or aggressive Media it has proven to be useful to use a support ring. The fat of the support ring made of a suitable material, e.g. polypropylene, fluoroplastic or ceramic should correspond to the thickness of the molded spacer ring.
In einem Ausführungsbeispiel gemäß Zeichnung sei die Erfindung veranschaulicht: Der Gegenflansch 1 wird mit dem Anpreßdruck P auf den Runddichtring 3 gedrückt. Dabei ist der Verformung des Runddichtringes eine Grenze gesetzt, die dann erreicht wird, wenn der Gegenflansch 1 auf dem angeformten Distanzring 4 aufsitzt. Mit Hilfe des ebenfalls angeformten Haltekragens 5 wird die Ringdichtung auf den Flansch 2 aufgezogen und zentriert. 6 zeigt den eingesetzten Stützring.The invention is illustrated in an exemplary embodiment according to the drawing: The mating flange 1 is pressed onto the O-ring 3 with the contact pressure P. There is a limit to the deformation of the O-ring, which is then reached when the mating flange 1 is seated on the molded spacer ring 4. With help of the retaining collar 5, which is also molded on, the ring seal is placed on the flange 2 raised and centered. 6 shows the support ring used.
