Pipe connection. Patented in the German Empire on May 21, 1920.

According to the Union Treaty of June 2, 1911, priority is due to this application of the application in England on April 4, 1919.

It is already known to 'abut pipe ends through annular, iniit inward directed flanged sealing body to connect with each other, wherein the Pressure prevailing inside the pipe against the flanges acts to keep them tight To keep plant on the outer pipe wall. In the 'previously known versions this type consists of the entire sealing body, so both the outer cylindrical part as well as the inwardly directed adjoining this part on the front sides Flanges made of roughly the same strength, flexible material. The material must be in the Flanges so soft and pliable that the flanges when the pipe is pushed in yield sufficiently in the sealing ring. From this there arises the evil that the outer cylindrical part is too soft and rolls around when inserting the flanges, so

! Ir.

that a cumbersome work is required to put the ring in the correct position to bring the pipes.

The invention aims to provide a pipe seal or pipe connection of the type mentioned create, which does not have this disadvantage and in which one can easily get the Can push the pipe ends into the connector without it rolling up, ίο and in spite of that, even with a rough one Outer wall of the pipe, a good seal due to the tight fit of the flanges on the outer wall of the tubes is reached. To this end, according to the invention, the actual cylindrical body of the connecting and sealing piece relatively executed stiffly, while the adjoining it, protruding inward Flanges are bevelled to slightly resilient, highly flexible lips.

The drawing shows several exemplary embodiments of the invention, namely:

Fig. Ι and 2 cross sections of two embodiments of the sealing ring; Fig. 3 shows such a ring in a non-compliant housing;

Fig. 4 is a section showing the arrangement of the ring when two tubes are connected;
Fig. 5 shows a modification thereof;

Fig. 6 shows a high pressure application;

Fig. 7 Ibis 10 show further modifications. In the drawings, 1 denotes the sealing ring, its cylindrical outer part is relatively stiff and has flexible, inwardly directed edges 2. For stiffening 'You can provide the ring 1 with a rigid housing 3, which from Steel or other material is made; in certain cases the stiffening can also by stronger ulcanization of the outer one Part made or by inserting stiffening materials in the manufacture of the ring. The production of the sealing connection is shown in Figs. The front sides of the pipes 4 to be connected to each other are from the two sides driven into the ring 1 so that the flexible edges 2 are close to the outer wall of the pipes. To ensure a tight connection of the edges 2 of the ring 1 with the To secure pipe ends, their inner diameter can be adjusted before inserting the pipe ends be a little smaller than the outer diameter of the tubes. The annular space 5 forms a pressure space in which the pressure inside the pipeline enters, and so on presses the flexible edges 2 onto the tubes.

In certain cases the sealing ring described can be used alone, and either according to Fig. 4 or, if it is desired, that the pipe outer surface everywhere has the same diameter by inserting it into a recess 6 (Fig. 5).

If a high level of security is required, it is advisable to provide a device which secures the ring 1 in its position. A thawed ring 7 (Fig. 6) can be used for this purpose, the outer periphery of which is preferably beveled and its two parts by a Outer belt 8 made of steel or the like driven over it are held together. To each The ring 7 with flanges 9 can prevent longitudinal movement of the tubes relative to one another be provided, which enclose in grooves 10 at the pipe ends, you can abier also on Arrange flanges 11 on the pipes (Fig. 7), which fit into grooves 12 of ring 7.

In Fig. 7 it is also shown at the same time that in place of the middle retaining strap 8 a Pair of rings ader band pair 13 can apply, which on the correspondingly conical Flanges 14 of the ring 7 are driven up.

In Fig. 8 an embodiment is shown, in which the ring halves, which form the retaining ring 7, are connected to one another by a joint 15 can be connected and locked by a locking pin 16. The pen 16 goes through eyes on both parts of the ring 7. In Fig. 9 is the retaining ring 7 undivided, the pipe ends are inserted here from the side and then the retaining ring 7 is fixed by the adjusting screws 17.

A modification of this embodiment • is shown in Fig. 10, in which in recesses of the ring 7 a number of toothed segments 18 is inserted, which by adjusting screws 19 are held in place.

Claims (1)

Patent claim: Pipe connection with an annular, with inwardly directed flanges provided sealing body, in which the prevailing inside the pipe Pressure presses the flanges firmly onto the pipe ends, characterized in that the outer body of the sealing ring is relatively stiff and the flanges too resilient, highly flexible edges or lips are beveled. 1 sheet of drawings.
