Description
Elastische Armaturen-Verbindungsröhrchen mit an den Enden aufgestauchten und gebördelten Bunden, aufgeschobenen Überwürfmuttern und Dichtungen sind bekannt. Diese Einrichtungen haben den Nachteil, daß sie meist nicht dichthalten; das Wasser dringt zwischen den Oberflächen der Dichtung einerseitsund den angebördelten Bunden bzw. Ärmaturenteilen andererseits radial nach außen.Elastic fittings connecting tubes with swaged ends and flanged collars, pushed-on union nuts and seals are known. These facilities have the disadvantage that they usually do not hold tight; the water penetrates between the surfaces of the seal on the one hand and the flanged collars or fitting parts on the other hand, radially outwards.
Der Erfindung liegt die Aufgabe zugrunde, diesen Mangel zu beheben.The object of the invention is to remedy this deficiency.
Die Lösung dieser Aufgabe besteht darin, daß die auf die Dichtung wirkende Fläche des Bundes schräg, also kegelig nach außen und unten verläuft, so daß beim Anziehen der Mutter die üblicherweise plane Dichtung an ihrem inneren Rand früher und stärker zusammengedrückt wird als außen. Hierdurch wird eine vollkommene Abdichtung erreicht.The solution to this problem is that on the seal acting surface of the federal government obliquely, so conical outwards and downwards, so that when tightening the nut, the usually planar seal on its inner edge is compressed earlier and more strongly than outside. This makes a perfect one Sealing achieved.
Zweckmäßig verlaufen auch die Andrückfläche der Mutter und die der Dichtung gegenüberliegende Fläche des Bundes entsprechend kegelig.The pressing surface of the mother and that of the also expediently run Seal opposite face of the collar correspondingly conical.
Zum Ausgleich des Auflagedruckes zwischen Mutter und Bund kann eine entsprechend kegelige, als Gleitfläche wirkende Beilagscheibe vorgesehen sein. Die Figur zeigt ein Ausführungsbeispiel; a ist das eine Ende des elastischen Verbindungsröhrchens, das an den Armaturenteil b angeschlossen werden soll. Der Anschluß des anderen Endes des Röhrchens an den zweiten Armaturenteil erfolgt in der gleichen Weise, wie in der Figur gezeigt, und wird daher nicht näher beschrieben. Das elastische Verbindungsröhrchen a besitzt einen aufgestauchten und gebördelten Bund c, welcher dem Anschlußteil d der Armatur b gegenüberliegt. Zwischen den Teilen c und d befindet sich die Dichtung e, die, wie üblich, von vornherein ein planparalleler Körper ist. Der aufgestauchte und gebördelte Bund verläuft schräg nach unten und außen, hat also die Form eines Kegelstumpfmantels. Auf dem Teil d der Armatur b sitzt eine Überwurfmutter u, deren Andrückflansch i wirkseitig entsprechend kegelstumpfförmig geformt ist. Zwischen diesem Flansch und dem Bund c befindet sich eine entsprechend kegelstumpfförmige Beilagscheibe m, die zum Ausgleich des Auflagedruckes dient und als Gleitfläche wirkt.To compensate for the contact pressure between the nut and the collar, a correspondingly conical washer acting as a sliding surface can be provided. The figure shows an embodiment; a is one end of the elastic connecting tube that is to be connected to the fitting part b. The connection of the other end of the tube to the second fitting part takes place in the same way as shown in the figure, and is therefore not described in more detail. The elastic connecting tube a has an upset and crimped collar c which is opposite the connection part d of the fitting b. Between the parts c and d is the seal e, which, as usual, is a plane-parallel body from the start. The upset and flanged collar runs obliquely downwards and outwards, so it has the shape of a truncated cone jacket. On the part d of the fitting b sits a union nut u, the pressure flange i of which is formed in the shape of a truncated cone on the effective side. Between this flange and the collar c there is a correspondingly frustoconical washer m, which serves to compensate for the contact pressure and acts as a sliding surface.
