Abstract

A muff for the union of pipe conduits is composed of a flexible, bendable sheet metal ring in the form of a cylindrical section, which is cut open approximately parallel to its longitudinal axis, and its lengthways edges are drawable together by means of draw closures. The closures take the form of a toggle lever. Between the muff and the pipe ends a sponge rubber seal is fitted. On the muff inner wall at least one lengthways running strip is incorporated. The coupling allows the pipe ends to abut face to face, and takes up no space axially.

Description

11Muffe zur Verbindung von Rohrleitungenn Die Erfindung betrifft eine Muffe zur Verbindung von Rohrleitungen.11 sleeve for connecting pipelines The invention relates to a Socket for connecting pipes.

Bekannt sind zu diesem Zweck sogenannte Schrumpfmuffen, in welche die beiden Rohrenden hineingesteckt werden. Dann wird die Schrumpfmuffe erwärmt. Durch das Erkalten der Muffe wird eine luftdichte Verbindung geschaffen.So-called shrink sleeves are known for this purpose, in which the two pipe ends are inserted. Then the shrink sleeve is heated. When the socket cools down, an airtight connection is created.

Die bekannte Vorrichtung ist mit dem Nachteil behaftet, dass sie an unzugänglichen Stellen schwierig zu montieren ist. Ausserdem müssen Geräte zum Erwärmen der Muffe zur Baustelle mitgebracht werden. Dazu kommt noch, dass man die Rohre so lange festhalten muss, bis die Schrumpfmuffe so kalt geworden ist, dass sie von selbst hält.The known device has the disadvantage that it is at difficult to assemble in inaccessible places. In addition, devices must be used for heating the socket to be brought to the construction site. In addition, you have the pipes must hold on until the shrink sleeve has become so cold that it can be removed from itself holds.

Aufgabe der Erfindung ist es, diese Nachteile zu beseitigen.The object of the invention is to eliminate these disadvantages.

Dies wird dadurch erreicht, dass eine Muffe zur Verbindung von Rohrleitungen geschaffen wird, welche erfindungsgemäß aus einem elastischen, biegsamen Blechring in Form eines Zylinderabschnitts besteht, der mindestens annähernd parallel zurnlängsachse aufgeschnitten ist und dessen Längsränder mittels eines eine Zugwirkung ausübenden Verschluß zusammenziehbar sind.This is achieved by having a sleeve for connecting pipes created is, which according to the invention from an elastic, flexible sheet metal ring in the form consists of a cylinder section which is at least approximately parallel to the longitudinal axis is cut open and its longitudinal edges by means of a pulling effect Closure are contractible.

Nach einem weiteren vorteilhaften Merkmal der Erfindung wird als Verschluß mindestens ein Kniehebelverschluß verwendert.According to a further advantageous feature of the invention is used as a closure at least one knee lever lock is used.

Dabei wird zwischen den beiden Rohrenden und WTuffen Moosgummi angeordnet, so daß eine völlig luftdichte und gasdichte Abdichtung geschaffen wird, die den Vorteil aufweist, daß sie lösbar ist.Foam rubber is placed between the two pipe ends and WTuffen, so that a completely airtight and gas-tight seal is created that the Has the advantage that it is detachable.

Nachfolgend wird die Erfindung an Hand eines Ausführungsbeispiels mit Hilfe von schematischen Zeichnungen näher erläutert: Es zeigen 1 und 2 die beiden Rohre die miteinander verbunden werden sollen. 3 ist die Muffe, 4 und 5 Kniehebelverschlüße. Zwischen der Muffe 3 und den Rohren 1 und 2 ist zum Abdichten ein Moosgummiring 6 bzw. 7 angeordnet.The invention is described below on the basis of an exemplary embodiment explained in more detail with the aid of schematic drawings: FIGS. 1 and 2 show the two Pipes that are to be connected to each other. 3 is the socket, 4 and 5 toggle locks. Between the sleeve 3 and the pipes 1 and 2 is a foam rubber ring for sealing 6 or 7 arranged.

Die aus Hartgummi bestehenden längslaufenden Streifen 8, von denen mehrere vorhanden sind, dienen dazu, das Verschieben der Muffe gegenüber den Rohren zu vermeiden.The longitudinal strips 8 made of hard rubber, of which several are available, serve to move the sleeve relative to the pipes to avoid.

Zweckmäßig wird der Moosgummi 6 und 7 in Sicken 9 und 10 angeordnet (Fig. 2).The foam rubber 6 and 7 is expediently arranged in beads 9 and 10 (Fig. 2).
