" Connector for making pipe connections "

In pipeline construction it is often necessary to create a T-joint between two pipes, whereby the branched line usually has a smaller diameter than the main line. Either a separate T-piece can be used or a hole can be created in the wall of the larger pipe. In the latter case there are several known ways of making the connection. For example, the branch line can be in an already provided reinforcement or support screwed or a socket provided with a self-tapping thread in screw the hole in or use a snap ring inside the tube.

You get an even, better connection when you use it a pipe s does ζ ens with. saddle-shaped flange which is designed so that it faces the inner surface of the larger pipe fits and through the opening in the pipe wall to the outside, so that the flange is against the inner Area lays. However, such a connector has the Uaehteil that it is inserted into the larger pipe from the inside must become. The problem on which the invention is based is to remedy this disadvantage. ; ..

Based on a "connector with a hollow nozzle, which is externally threaded and has a saddle-shaped flange, the invention consists in that the Flange has two oppositely lying flattened areas and a collar surrounding it to form an annular space for receiving a sealing ring. Using Such a connector, the connection is made in such a way that one in the wall of the larger pipe a "But made by a diameter knife that is bigger is than the distance between the edges of the flattenings of the connector, this pushes it in through the hole from the outside and rotates inside the larger tube to make the flange in abutment with the inner surface of the outer To bring the pipe, whereupon a seal on the outside between the nozzle and the wall of the larger pipe is made around the Iioeh, in which a sealing

ring is inserted into the ling space between the socket and the pipe wall is formed by the collar. Afterward a nut is screwed onto the socket to fix the connector, whereupon the end of the smaller one Pipe connected to the connector in any suitable manner can be. Among other things, it is possible to provide the smaller pipe to be connected with an internal thread and even to use as a mother on the outside Nozzle is removed to compress the seal.

Although thus the smaller pipe over the nozzle can be screwed, it corresponds to the preferred embodiment of the invention to have an internal thread in the connecting piece To accommodate the smaller pipe or to provide a connecting piece by means of which the smaller pipe is held will.

An exemplary embodiment is shown in the drawing. Show it

.. The in Pig illustrated elements 1 "are the real connector 1, a connecting sleeve 2, a seal ring 3 ₅ a nut 4, - a frustoconical Druekring 5 and a nut 6.

The connector 1 consists of a socket 7 with an external thread and an internal thread and a saddle-shaped planar 8, on which two diametrically opposed flattened areas 9 and a collar 10 are formed, such as in particular made of Pig. 3 emerges. The total axial length of the connector 1 is smaller than the diametrical distance between the edges of the flattened areas 9. To do this; allow, the hole has a diameter that is greater than the diametrical distance between the edges of the flats 9, but smaller than the diameter of the paddling nest. During insertion, the axis of the connector is at about 90 ° to the axis of the hole in the pipe 11. The connector is then pivoted through this angle so that the bent parts of the Plansche © 8 are brought into fitting, snug contact with the inner surface of the pipe wall can. The sealing ring 3 is now placed in the annular space that has arisen between the connecting piece 7 and the edge of the hole in the pipe 11, and is then pressed together by the nut 4. This creates a good seal around the

The threaded inde of a second pipe can now be screwed into the bore of the connecting piece 7 whose diameter is designated in Pig * 2 as D2. The prerequisite is that the pipe and the bore have matching dimensions. On the other hand, does the second pipe have one relatively small diameter, the connecting sleeve 2 is screwed into the socket.

The nut 4 has a shoulder 12 which engages over the upper part of the sealing ring 3. This sets the trend of the ring 3 counteracted spreading apart radially, if the. Mother is attracted. In this way it is possible to put more pressure on the ring and thus improve the quality of the seal.

In general, the axes of the two are too

By means of the invention, a mechanically strong and strong pipe connection can be produced, either before or after laying the main line. The invention is also suitable for combining "metallic and non-metallic Pipes with each other, or with each other and both for pipes; who work under pressure, as well as for those in which there is no significant pressure. The connector can be made of metal or plastic or other work. consist of material.
