"Socket pipe connection"

The innovation relates to socket pipe connections, and ζτ / ar in particular, if not exclusively, those for thin-walled sheet metal pipes intended for pipelines, their The intended use requires that the shots are quickly and reliably connected to one another in a sealing manner and to one another again can be solved, and that also a certain Abwinke development of the successive pipe sections is possible.

Such "prerequisites are in numerous cases, e.g. Irrigation and sprinkling systems, ventilation lines, for those in the mining industry in boreholes »introduced and in the train their importation extended to the depths of the borehole G-as from suction lines etc. before.

The socket pipe connection according to the control is in a new way Way of using the principle of the bayonet lock

made. It is basically characterized in that the The edge of the sleeve, which is made of sheet metal like the pipe, is bent inwards so that the inner wall of the 1M bend the Surrounds the pipe tip to be introduced into the socket with little play and the bar formed by this bent area has a plurality of recesses, the number and size of which is the same as that of or from the pipe circumference of the pipe tip corresponds to warts placed on them. When the ear tip is pushed into the socket, these wart approaches pass through the Recesses in the inwardly bent edge strip of the socket, whereupon by a simple turn of the inserted into the socket Pipe tip and slight backward movement of the same, the lugs to rest on non-recessed areas the edge strip come and the connection is locked. By

En the side of the recesses formed increase / the edge strip This prevents the pipe tip from being turned back and thus accidentally loosening the connection.

Appropriate sealing means are used between the pipe tip and the socket provided that when inserting the tube tip preferably slightly bent inward at its end edge be deformed or compressed and, as soon as after the insertion of the pipe tip into the socket, the pipe tip so far that she comes to rest on the bead has been moved back is to secure the seal.

The new socket pipe connection enables at the same time how

apparent, within certain limits established by the systematic the intended play between the inner edge of the bent strip at the socket end and the circumference of the pipe tip is given, an Aby / inkelung / aerart interconnected pipe sections to each other without the seal being endangered. For this purpose, the sealing body can also be in his The upper area should be slightly cut out on the inside, so that the sealing surface in the normal state is somewhat backwards from the end edge the tip of the pipe.

In the figures is an embodiment of the new socket pipe connection, in application to the connection of the sections of a gas evacuation line laid in a borehole shown.

Mg. 1 is a longitudinal section through the new socket pipe connection, the left half shows the phase after the insertion of the tip into the socket pipe, while the right half represents the locked connection after slight rotation and retraction of the pipe tip.

Mg. 2 is a section on line A-B of Pig. I, that too reveals the two phases.

The pipe section having the socket c and the pipe section to be connected to it is marked with a. The welded to the socket pipe a Socket c is according to the firing in its binding area,

as can be seen at d, flanged inwards towards the pipe tip, leaving a small amount of play e. The educated Edge strip f has recesses g distributed over its circumference, namely at least two, but possibly also several such Recesses which are dimensioned so that they allow the passage of warts h which are arranged on the pipe tip and pressed out of it according to the exemplary embodiment äby subsequent slight rotation of the tube b, in the course of which they pass the bulges i arranged next to the recesses and slight backward movement of the tube to the Raising on the non-recessed areas of the skirting d of the socket.

According to the exemplary embodiment, the ind edge of the pipe tip is also bent slightly inwards, as can be seen at k, about the insertion of the tube b and thereby the deformation process of the sealing body 1 inserted into the socket. This sealing body is inside in its band area slightly conical excepted, so that the seal after the slight backward movement of the pipe tip slightly backwards is relocated in order to avoid the bends of the two pipes connected to one another by the left at e Play are possible to ensure the proper seal.

The number of projections h and recesses g to be provided on the pipe circumference of the bent part of the socket is dependent chosen by the diameter of the pipe. With pipes

of small diameter on the order of 100 mm suffice two such warts, when using the basic concept of the new connection, e.g. on ductwork with one With a diameter of 600 mm and more, a correspondingly larger number of such warts is provided.

In general, of course, the fire is not aimed at that The exemplary embodiment described in detail above and shown in the figures is limited, but are on the other hand, changes are possible without deviating from their basic idea.

Claims (6)

-6- RA. 792 522M2.1Z62 / - Protection claims: 1. socket pipe connection, especially for sheet metal pipes of low "found strength, characterized in that the socket in its The end region is bent inward and has recesses in this bent part, which allow the passage of at the Warts arranged at the pipe tip allow after the pipe tip has been inserted into the socket, twisting of the same while passing of bulges arranged next to the recesses and slight backward movement of the inserted pipe rest on the bent inner sand of the sleeve. 2. socket pipe connection according to claim 1, characterized in that that the warts are extrusions from the sheet metal of the tubular body. 3. socket pipe connection according to claim 1 and 2, characterized in that that the recesses in the bent part of the sleeve and the warts in a number of at least two in more uniform Distribution over the pipe circumference are provided. 4. socket pipe connection according to claim 1 to 3, characterized in that that there is little play between the inwardly bent edge of the sleeve and the circumference of the pipe tip is. 5. socket pipe connection according to claim 1 to 4, characterized in that that the end edges of the pipe tip are bent slightly inward. 6. socket pipe connection according to claim 1 to 5, characterized in that that the sealing body made of elastic material inserted into the deepest part of the socket is in its inner area on the inside is slightly conical excepted, so that the sealing surface in the sealing effect even with bends of the two Pipes maintaining each other at a® distance is moved backwards from the lower edge of the pipe tip.
