Detachable coupling for pipelines, in particular for those made of sheet metal pipes. .

The present invention relates to a detachable Coupling for pipelines, in particular for those made of sheet metal pipes, which coupling in a known manner takes the form of a resilient, slit ring in one piece and with inwardly directed flanges or similar projections, grip the outwardly directed edge beads on the pipeline parts following one another and clamp them together can, and is provided with a clamping device attached to the slot for closing the ring.

Such couplings are very often used in interim pipelines, e.g. for pneumatic transport of grain or other bulk material, whereby a quick laying or dismantling of the pipelines is desired, but can also be used advantageously in permanent systems, especially in those where there is a need to connect the pipeline to one or more of them from time to time To be able to take apart bodies.

The said clamping device can more expediently

wise be an ordinary toggle clamp device that is on

Ring is attached on one side next to the slot and its clamping bracket in a fitting on the other side of the The slot engages.

Such detachable coupling rings can provide a secure and, depending on the circumstances, sufficiently tight connection Represent two successive sections or parts of the pipeline, but are often difficult for a single man as he usually uses both hands to unlock the Ring must use to attach it over the edge bulges of the pipes and to close it so that it does not Hand more to align the two, or at least one of the

has free both line sections concerned.

The purpose of the present invention is to

specify a coupling ring that is suitable for operation with a Hand is well suited, making it a substantial saving in manual labor when laying and dismantling a pipeline system makes possible.

The coupling according to the invention is characterized in that the ring in its rest position has an inner diameter which is somewhat smaller than the outer diameter is the edge beads of the line parts and that the clamping device is also set up to the ring of to expand this rest position from and to determine in this expanded position in which position the inner The diameter of the ring is slightly larger than the outer diameter of the edge beads.

If such a coupling is used to connect two

consecutive parts or sections of a pipeline are used is to be, it is only expanded from the rest position and pulled over the edge bead of one section. Then, while the resilient ring is kept expanded with the aid of the tensioning device, the edge bead of the other portion brought into engagement with the ring. This then holds the two sections together loosely in its rest position until the clamping device for closing the ring around the two pipe sections is operated »This final clamping can of course immediately after the provisional connection of the sections, but in most cases this is best done only when

■ -.- ■ '

when the entire pipeline system or a substantial part of it has been provisionally assembled. The coupling rings not yet tensioned allow a certain movement of the individual pipe sections, so that they can be moved relative to one another and in relation to their surroundings as desired be able.

An embodiment of the coupling according to the invention is shown on the drawing, whose

Fig. 1 shows the complete coupling ring in its rest position, whose

Fig. 2 and 3 show the right half of the coupling ring in an expanded or clamped position, and their

Fig. H shows a section transversely through the resilient coupling ring.

In the embodiment shown, the coupling

ment mainly from a resilient, slit ring 1, which has a cross-section like that shown in Fig. U. The ring thus has a central bead that can accommodate a sealing ring 2, and two inwardly directed flanges 3, which grip outwardly directed edge beads 4 at the ends of two pipeline sections 5 following one another and can clamp them together.

At one end of the resilient ring 1, i.e. on the one side next to its slot 6, there is a pin 7 one arm £ supported, which is in a double-acting toggle lever clamping device enters, which also includes a clamp 9, of which it is assumed in the drawing that it is from consists of a closed wire ring, on the one hand through a hole 10 in the arm Ö and on the other hand through a hole 11 in a Fitting 12 extends to the one on the other side of the slot 6 is attached to the ring 1.

In Fig »1, the toggle lever clamping device is in their released position shown, in which it is the resilient Ring 1 allows to assume its natural position or rest position · When the arm S is folded in the direction of the In the position shown in Fig. 2, the resilient ring 1 is expanded or unlocked and in the position in Fig. 2, the clamping device has passed a dead center position, so that it the ring 1 detects in its unlocked form. The big ones— Ratios are adjusted so that the ring 1 is in this position can be drawn freely over the edge beads 4 of the pipeline sections 5.

If the clamping device is returned to the position shown in FIG. 1

brought back position shown, so the ring 1 springs back inside and thereby holds the pipe sections 5 together provisionally, as has already been described above. The final clamping of the sections 5 can then to happen at any arbitrarily selected point in time, namely by moving the arm ß clockwise to the position shown in FIG. 3 Position is turned over, which causes the slot 6 in the resilient ring 1 to be closed. The two pipe sections 5 are then securely and tightly connected to one another with the aid of the coupling.
