Erfindung befasst sich mit einer druckfenten Verschraubung vorzugsweise für Wasser- , Öl- bzw.Hydraulikrohre. The invention deals with a pressure-tight screw connection, preferably for water, oil or hydraulic pipes.
Bekannt sind Verschraubungen, bei denen beim Anziehen einer Überwurfmutter ein Schneidring in das Rohr eingepresst wird, der zugleich durch Andrücken gegen eine konische Dichtfläche eine Dichtwirkung erzeugt. Von Nachteil sind dabei dr-r relativ hohe Preis und die nicht immer gewährleistete üichtwirkung. Besonders bei mehrmaligem Lösen und bei zu starkem bzw. zu schwachem Anziehen der Überwurfmutter tritt häufig Leckflüssigkeit auf.Screw connections are known in which when tightening a Union nut a cutting ring is pressed into the pipe, which at the same time by pressing against a conical Sealing surface creates a sealing effect. Disadvantages are the relatively high price and the not always guaranteed ight effect. Especially with repeated loosening and with closed If the union nut is tightened too much or too weakly, leakage fluid often occurs.
Bei anderen Verschraubungen werden die Rohre direkt angeschweißt. Die dabei auftretenden Spannungen bedingen eine Nachbehandlung, die zeitraubend und teuer ist.With other screw connections, the pipes are direct welded on. The stresses that arise in this process require post-treatment, which is time-consuming and expensive.
Ebenfalls bekannt sind Flansche, bei denen das Rohr eingeklebt wird. Das Kleben von Metallen ist jedoch im allgemeinen nicht werkstattgerecht, da bei beiden Teilen eine metallisch saubere Oberfläche Voraussetzung ist. Das Anmischen der zur Verwendung gelangenden Zwei-Komüonenten-Kleber ist zudem problematisch.Flanges in which the pipe is glued in are also known. However, bonding of metals is in generally not suitable for the workshop, as both parts a metallically clean surface is a prerequisite. Mixing the two-component adhesives used is also problematic.
Erfindungsgemäß werden diese Nachteile dadurch vermieden, daß der benötigte Klebstoff bereits vorportioniert in den Hülsender Plansche bzw. Verschraubungen vorhanden ist. Es wird vorgeschlagen, die Komponenten des Klebers in Punkten (14), Ringen (15) oder Streifen (9,lo) innerhalb der Hülsen (3»4) zu verteilen und mit einer sehr dünnen, hermetisch abschließenden Kunststoffschicht (13) zu überziehen. Beim Einsetzen des Rohres (2)(l) wird der Kunststoff aufgerissen und abgestreift. Dabei vermischen sich beide Komponenten (11,12) sehr gründlich. Der Kunststoff wird in die vorhandenen Hohlräume (7) gedrückt und verhärtet dort mit dem Kleber.According to the invention, these disadvantages are avoided by that the required adhesive is already pre-portioned in the sleeves of the plansches or screw connections. It is suggested that the components of the adhesive in points (14), rings (15) or strips (9, lo) inside of the sleeves (3 »4) and with a very thin, hermetically sealing plastic layer (13) overlay. When the tube (2) (l) is inserted, the plastic is torn open and stripped off. Mix in the process both components (11,12) very thoroughly. The plastic is pressed into the existing cavities (7) and hardens there with the glue.
Die gesamte Verschraubung (Pig.l) besteht aus zwei Hülsen (3»4) ,einer Überwurfmutter (6) und einem O-Ring (16), der eine unproblematische Dichtwirkung gewährleistet.The entire screw connection (Pig. 1) consists of two sleeves (3 »4), a union nut (6) and an O-ring (16), the ensures an unproblematic sealing effect.

Die Verschraubung bietet keinerlei Ströirmngswj dor.'Hände. Die Klebung ist wie die O-Ring-Abdichtung bi3 etwa 800O druckfest. Das Ablängen der Rohre bedarf keiner besonderen Sorgfalt, da auch bei nur teilweise eingeschobenem Rohr ausreichende Dichtwirkung besteht. Verspannungen treten nicht auf, da das Rohr in seiner endgültigen Lage aushärten kann. Äußere Kräfte, die auf das Rohr einwirken, haben keinen Einfluß auf die Abdichtung.The screw connection offers no flow of air to the hands. Like the O-ring seal bi3, the bond is pressure-resistant to around 80 0 O. Cutting the pipes to length does not require any particular care, as there is sufficient sealing effect even if the pipe is only partially inserted. Tension does not occur because the pipe can harden in its final position. External forces acting on the pipe have no effect on the seal.
Zur Vorbehandlung des Rohres genügt eine einfache Bürst-Schleif- oder Sandstrahlvorrichtung, in die das Rohrende nach dem Entgraten gesteckt wird.A simple brush-sanding device is sufficient to pre-treat the pipe. or sandblasting device into which the pipe end is inserted after deburring.
Statt einer zweiten Hülse (4) kann die Verschraubung auch gegen eine T-Verschraubung o.fl. geschraubt werden.Instead of a second sleeve (4), the screw connection can also be used against a T-screw connection or similar. be screwed.
Fig.6 zeigt eine Planschverbindung mit in der beschriebenen Weise eingeklebten Rohren.6 shows a splash connection with in the described Way glued pipes.
Die zu verbindenden Rohre können je nach Anwendung3fall ebenso wie die Rohrverbinder v/ahlweise aus Metall oder aus Kunststoff sein.The pipes to be connected can vary depending on the application as well as the pipe connectors may be made of metal or plastic.
