Description
Die Erfindung. betrifft einen elastischen Dichtungsring für . Rohrverbindungen, und zwar insbesondere solche für Muffenrohre mit Gewinde-Stopfbüchse derjenigen Art, die mit Bewehrungen'' an den beiden schmalen Stirnflächen aus nachgiebigem, gegenüber dem eigentlichen Werkstoff des Dichtungsrings steiferen Werkstoff versehen sind.The invention. relates to an elastic sealing ring for. Pipe connections, and in particular those for socket pipes with threaded gland of those Type, which with reinforcements '' on the two narrow end faces made of flexible, provided a stiffer material compared to the actual material of the sealing ring are.
Diese Bewehrungen weisen erfindungsgemäß sich " über die jeweiligen Stirnflächenbreite erstreckende, von zwei Bogen begrenzte Querschnitte etwa, mondsichelförmiger Gestalt auf. Vorteilhaft besteht der ' \Verkstoff des eigentlich dichtenden Teils des Dichtungsrings aus Weichgummi geeigneter laastizität und Härte, die Bewehrungen hingegen aus entsprechend härterem und steiferem Weichgummi, aus Leder oder auch aus einem geeigneten Gummiersatzstoff. Der Teil des Dichtungsrings zwischen den Bewehrungen gewährleistet die eigentliche Abdichtung der Verbindung und Dichterhaltung im Betriebe, und zwar infolge von Vorspamiungen, die dem Dichtwerkstoff vor dem Einbringen des Dichtungsrings zwischen der Muffe des einen Rohrs und dem Spitzende des folgenden Rohrs gegeben wurde. Die Vorspannung kann aber auch in gleich günstiger Weise erst beim Einbringen des Dichtungsrings in den Raum zwischen Muffe und Rohrspitzende aufgebracht werden, und zwar als Reaktionswirkung gegeniil>er (lern notwendigen Einl)ringdrtiek.According to the invention, these reinforcements are "over the respective Cross-sections that extend frontal width and are delimited by two arches, roughly crescent-shaped Shape up. Advantageously, there is the material of the actually sealing part the sealing ring made of soft rubber of suitable elasticity and hardness, the reinforcements on the other hand, made of correspondingly harder and stiffer soft rubber, leather or even from a suitable rubber substitute. The part of the sealing ring between the Reinforcement ensures the actual sealing of the connection and retention of the seal in the company, as a result of vorpamiungen that the sealing material before Insertion of the sealing ring between the socket of one pipe and the spigot end of the following pipe. The preload can also be cheaper Only when the sealing ring is inserted into the space between the socket and the end of the pipe spigot be applied as a reaction effect against them (learning necessary Einl) ringdrtiek.
Die Übertragung der an den Verbindungsstellen etwa durch Rohrverlagerungen od. dgl. auftretenden Kräfte erfolgt dagegen nicht vom eigentlichen Dichtungswerkstoff, sondern durch die vorgesehene Bewehrung der 'beiden Dichtungsringstirnflächen, so daß der Dichtungsstoff von äußeren Kräften praktisch entlastet ist. Erreicht wird die durch die mondsichelförmige, sich über die Stirnflächenbreite erstreckende Querschnittsform der Bewehrungen in Verbindung mit dem, verhältnismäßig harten und in sich steifen Bewehrungswerkstoff. Beim Einbringen des Dichtungsrings in den zwischen Muffe und Spitzende gebildeten Raum, etwa mit Hilfe einer Gewindestopfbüchse, verklemmen sich unter der Wirkung des EinpreBdrucks die Bewehrungen mit wachsendem Druck in hervorragender Weise mehr und mehr an den gegenüberliegenden Wandflächen, während der eigentliche Dichtwerkstoff infolge seiner großen Elastizität sich nicht zu verklemmen vermag. Beiderseits vom eigentlichen Dichtwerkstoff entstehen demnach zwei rundum laufende, trägerartige Körper, die praktisch allein die auftretenden Kräfte übertragen, während der dazwischenliegende Werkstoff nur noch die Abdichtung der Verbindung zu übernehmen braucht, dieser Aufgabe dann aber in hervorragender Weise gerecht wird. Die Bewehrungen dienen im übrigen gleichzeitig zum Fernhalten von Agenzien hauptsächlich aus den in den Rohrleitungen strömenden Gasen oder Flüssigkeiten, die den Dichtwerkstoff angreifen könnten und damit zerstören würden.The transmission of the at the connection points, for example through pipe relocations or the like occurring forces, on the other hand, do not come from the actual sealing material, but by the intended reinforcement of the 'two sealing ring end faces, see above that the sealant is practically relieved of external forces. Is achieved the crescent-shaped cross-sectional shape that extends across the width of the face the reinforcement in connection with the, relatively hard and inherently stiff Reinforcement material. When inserting the sealing ring between the socket and Spigot formed space, for example with the help of a threaded gland, jam under the effect of the grouting pressure, the reinforcement becomes more outstanding with increasing pressure Way more and more on the opposite wall surfaces while the actual Sealing material is not able to jam due to its great elasticity. On both sides of the actual sealing material, two all-round, carrier-like body that practically alone transmit the forces that occur while the intermediate material only has to take over the sealing of the connection needs, but then does justice to this task in an excellent way. The reinforcements serve at the same time to keep away agents mainly from the Gases or liquids flowing in the pipelines that affect the sealing material could attack and thus destroy.
Die Zeichnung veranschaulicht ein Ausführungsbeispiel der Erfindung, und zwar in Anwendung auf eine Schraubmuffenverbindung mit Gewindestopfbüchse. , Abb. i zeigt dabei den Dichtungsring im Anlieferungszustand und Abb. 2 im eingebrachten Zustand im lluffengrund.The drawing illustrates an embodiment of the invention, namely in application to a screw socket connection with a threaded gland. , Fig. I shows the sealing ring in the delivery condition and Fig. 2 when it is inserted Condition in the lluffengrund.
Es bezeichnet i den zwischen den Bewehrungen 2 und 3 der Stirnflächen vorgesehenen eigentlichen Weichgummidichtwerkstoff. Die Bewehrungen 2 und 3 sollen hier aus gegenüber dem Dichtgummi wesentlich härteren und in sich steiferen Weiehgum,mi gebildet sein.It denotes i between the reinforcements 2 and 3 of the end faces intended actual soft rubber sealing material. Reinforcements 2 and 3 should here made of significantly harder and inherently stiffer Weiehgum compared to the sealing rubber, mi be educated.
