Description

Glattrchrverschraubung für Höchatdrucke Mit der vorliegenden Glattrohrsohraubverbindung soll eine Verbindung für glatte, unbearbeitete Rohre geschaffen werden, die bei hydraulischen bruckechwankungen ohne Nachspannon absolut dicht bleibt und die Druekspitzen, die in jeder Hydraulik auftreten, durch ihre elastische Dichtung verhindern. Diese Verbindung ist auch für große Dimensionen geeignet. Smooth screw connection for high pressure prints With the smooth pipe screw connection a connection for smooth, unprocessed pipes is to be created, which at hydraulic bridge fluctuations without tension remains absolutely tight and the pressure peaks, which occur in every hydraulic system, thanks to their elastic seal. These Connection is also suitable for large dimensions.

Glattrohrverschraubungen verschiedener Art sind bekannte Bei allen Glattrohrverschraubungen wird mit Schneid- Dichtringen gearbeitet, die über Konen sich in das Rohr radial oder in die Verschraubung stirnseitig einschneiden und entsprechend verformen. (Durchmesser verkleinerung) Allen diesen Verbindungen haftet der Fehler an, daß bei steigenden oder wechselndem Druck die Dichtung versagt und ein Nachziehen der Verbindung von Zeit zu Zeit erforderlich wird0 Die Demontage des Schneidringes ist schwierig. Da die manuelle Anzugskraft ausschlaggebend für Halterung und Dichtung ist, bleibt die Anwendung auf kleine Dimensionen beschränkt.Smooth tube fittings of various types are known to all Smooth tube screw connections are made with cutting sealing rings that have cones Cut into the tube radially or into the screw connection on the front side and cut accordingly deform. (Diameter reduction) The error is liable to all of these connections indicates that when the pressure rises or changes, the seal fails and retightening the connection is required from time to time 0 Dismantling of the cutting ring is difficult. Since the manual tightening force is decisive for the bracket and seal is, the application remains limited to small dimensions.

Bei der zur Anmeldung vorliegenden Glattrohrverschraubung sind Dichtung und Halterung getrennt.In the smooth pipe screw connection available for registration, there are seals and bracket separately.

Bei Druskerhöhung des Mediums ii Rohr wird auteiatisch auch die Spannkraft der Halterung erhöht. Die Halteelemente (kein geschlossener Ring) werden nicht bleibend verformt, sondern nur tiefer in den Kegel der Spannmutter hineingedrückt. Dadurch wird die Haltekraft erhöht.When the pressure of the medium ii pipe is increased, the clamping force is also automatic the bracket increased. The retaining elements (not a closed ring) are not permanent deformed, but only pushed deeper into the cone of the clamping nut. Through this the holding force is increased.

Die Dichtung wird gleichzeitig Mit dem Halteelement vorgespannt und ist deshalb auch ohne Medium-Innendruck absolut dicht0 Da der benötigte Spanndruok sich automatisch nach den Innendruck des Mediums einstellt, ist die vorliegende Glattrohrverschraubung nicht an Dimensionen gebunden.The seal is pre-tensioned and simultaneously with the retaining element is therefore absolutely tight even without the internal pressure of the medium automatically adjusts itself according to the internal pressure of the medium, is the present one Smooth tube screw connection not tied to dimensions.

Die Abbildung zeigt eins solche Glattrohrverschraubung.The illustration shows one such smooth tube screw connection.

Über die Glattrchre 1 u. 2 wird die Schraubverbindung so aufgeschoben, daß beide Rohrenden etwa in Mitte der Schraubverbindung zusammenstoßen. Man kann auch erst ein Rohrende auf einer Seite der Verachraubung auf Mitte bringen und vorspannen und dann das andere Rohr bis zum Anschlag bringen. Die Ringkeiliutter 3 wird auf das Schraubstüok 4 geschraubt, wodurch das Ralteeleuent 5 in den Konus der Ringkeilmutter 3 durch den Druckring 6, der sich in einer Ausdrehung axial bewegt, eingeschoben wird. Die Halteelemente 5 werden auf das Rohr 1 und 2 gedrüokt, d. h. das Rohr 1 und 2 wird mit der Glattrohrverschraubung verspannt. Gleiehasiting verformt der Druokring 6 die Dichtung 7 so daß die Dichtung 7 sich diohtend zwischen Rohr und Schraubverbindung andrückt0 Bei steigendem Druck des Mediums wird der Druck auf das Halteelement 5 über die Dichtung 7, den Druckring 6 verstärkt, so daß sich die halterung nach dem Innendruck einstellt und sicher arbeitet.The screw connection is pushed on over the smooth barrels 1 and 2, that both pipe ends collide approximately in the middle of the screw connection. One can first bring one end of the pipe on one side of the screw connection to the middle and pretension it and then bring the other pipe up to the stop. The ring spline nut 3 is on screwed the screw 4, whereby the Ralteeleuent 5 in the cone of the ring spline nut 3 pushed in by the pressure ring 6, which moves axially in a recess will. The holding elements 5 are pressed onto the tube 1 and 2, i.e. H. the pipe 1 and 2 is clamped with the smooth pipe screw connection. Equal asiting deforms the Druokring 6 the seal 7 so that the seal 7 is diohtend between the pipe and Screw connection presses 0 When the pressure of the medium increases, the pressure is increased the holding element 5 on the seal 7, the pressure ring 6 reinforced so that the bracket adjusts according to the internal pressure and works safely.
