Description
Die Erfindung betrifft eine insbesondere für schmiedeiserne Rohre für hohen Druck geeignete, auf der Anwendung überschiebbarer Flanschringe und geteilter Bundringe beruhende Verbindung, die den Vorteil' bietet, daß der ; durch das Anziehen der Verbindungsschrauben entstehende Achsialdruck unmittelbar von der Rohrwand und nicht, wie dies bisher bei derartigen Rohrverbindungen der Fall ist, von denThe invention relates to a particularly suitable for wrought iron pipes for high pressure, based on the use of sliding flange rings and split collars, which has the advantage that the ; by tightening the connecting screws resulting axial pressure directly from the pipe wall and not, as was previously the case with such pipe connections, from the
ίο Dichtungsborden aufgenommen wird, so daß letztere durch Anstauchen oder Anschweißen der Rohrenden beliebig verbreitert und jede den Druckverhältnissen entsprechende Dichtungsart angewendet werden kann, ohne daß ein Verbiegen der Dichtungsborde zu befürchten ist, und demzufolge eine dauernd sichere Dichtung erzielt wird.ίο sealing flanges is added so that the latter widened as desired by upsetting or welding the pipe ends and each the type of seal corresponding to the pressure conditions can be used without a bending of the sealing rims is to be feared, and consequently a permanently secure seal is achieved.
Die Verbindung ist dadurch gekennzeichnet, daß die Bundlingteile an der Innenseite mit ringförmig verlaufenden Rippen versehen sind, mit welchen sie in entsprechende, außen auf den Rohrenden vorgesehene Ringrillen eingreifen Die Bundringe sind in an sich bekannter Weise mit kegeliger Sitzfläche für die innen entsprechend kegelig gestalteten Flanschringe und außerdem mit einem Anschlagbord bekannter Art versehen, gegen den sich der Flanschring nach vollständigem Aufschieben auf, die kegelige Sitzfläche am Bundring setzt.The connection is characterized in that the bundling parts on the inside with annular ribs are provided with which they are in corresponding, outside on the Engage the annular grooves provided at the ends of the pipe. The collars are in a manner known per se with tapered seat for the internally tapered flange rings and also provided with a stop rim of a known type, against which the flange ring after completely pushing it on, the conical seat is set on the collar ring.
Die Zeichnung veranschaulicht ein Ausführungsbeispiel der neuen Rohrverbindung.The drawing illustrates an embodiment of the new pipe connection.
Die Rohrenden α sind mit Ringrillen versehen, denen die an den Bundringteilen b innen vorgesehenen Ringrippen genau entsprechen. Die äußere Mantelfläche der Bundringteile b ist kegelförmig gestaltet und dieser Kegelform entspricht die Innenwandung der Flanschringe d. Beim Anziehen der Verbindungssehrauben e werden zunächst die Bundringteile b fest auf die Rohrwand gepreßt und alsdann nach vollende tem Eingriff der Ringrippen der Bundringteile in die Ringrillen der Rohrenden letztere bei weiterem Anziehen der Verbindungsschrauben aneinander gepreßt und so die erforderliche Pressung des Dichtungsmaterials herbeigeführt. Die Rohrenden selbst sind durch Stauchung oder Anschweißung derart verbreitert, daß breite Dichtungsflächen f entstehen. Ihre zulässige größte Breite wird durch die lichte Weite der Flanschringe d bestimmt, die in bekannter Weise über das Rohrende geschoben werden. Um beim Anziehen der Flanschringe d dem . hierbei durch die Bundringteile b auf die Rohre in radialer Richtung ausgeübten Druck eine Grenze zu setzen, sind die Bundringteile b in bekannter Weise mit einem. Anschlagbord c versehen, gegen den sich der Flanschring d setzt, so daß bei weiterem Anziehen der Verbindungsschrauben e.auf die Rohre nur noch ein längsgerichteter Druck ausgeübt wird, der ausschließlieh ein stärkeres Zusammenpressen des Dichtungsmaterials bewirkt.The pipe ends α are provided with annular grooves to which the annular ribs provided on the inside of the collar parts b correspond exactly. The outer circumferential surface of the collar parts b is conical and the inner wall of the flange rings d corresponds to this conical shape. When tightening the connecting screws e , the collar parts b are first pressed firmly onto the pipe wall and then, after the ring ribs of the collar parts are fully engaged in the annular grooves of the pipe ends, the latter are pressed against each other while the connecting screws are tightened further, thus bringing about the required compression of the sealing material. The pipe ends themselves are widened by upsetting or welding in such a way that wide sealing surfaces f arise. Their maximum permissible width is determined by the clear width of the flange rings d , which are pushed over the end of the pipe in a known manner. In order to tighten the flange rings d dem. To set a limit here by the collar parts b on the tubes in the radial direction pressure, the collar parts b are in a known manner with a. Provided stop rim c , against which the flange ring d sits, so that if the connecting screws e are tightened further, only a longitudinal pressure is exerted on the pipes, which only causes a stronger compression of the sealing material.
