Expansion compensator for pipelines

The innovation relates to expansion compensators for pipelines, with one the changes in the pipe length elastic receiving and Ii a housing mounted expansion body, which is mounted at one end in one pipe connection and received at the other end by the other pipe connection which is slidably guided on the corresponding end of the housing.

The innovation concerns in particular expansion compensators, which are preferred in the food industry and process engineering be used where a complete cleanability in the flow and a complete emptying without residues the expansion compensators are essential.

Curved pipe loops, Valtenbälge or are known axially telescopic tubes »which are sealed against one another by means of a sealing ring.

These known expansion compensators have the disadvantage of folds or crevices, which are poor, sometimes even cannot be cleaned in the flow at all. Moreover, stay there is residue left on the bellows and the pipe loops also have a high flow resistance.

The innovation has the object to improve this known expansion joints so that they can be cleaned completely emptied and the flow and have a comparatively low flow beyond _s

According to the invention, this object is achieved in that the expansion body is a hose with a smooth inner lining and with numerous beads lying next to one another on the outer circumference, and that the housing outside of the end regions has two has opposite guide surfaces, which create tangential to the beads of the hose in such a way that the hose is only in that during the pipe length change can move laterally between these two guide surfaces space.

In a further embodiment of the idea of the innovation, a reinforcing insert, e.g. a fabric or is in the hose a wire spiral provided.

Due to the special design of the expansion body! or of the housing, the direction of movement i is prescribed for the expansion body when the pipe length is changed, so to speak. If the expansion compensator is installed correctly, the expansion | body move only in the horizontal direction, which has the consequence that it can be easily cleaned and completely emptied in the flow. When the expansion body moves in the horizontal direction, “water sacs ^{11 are excluded}

An exemplary embodiment of the expansion compensator according to the innovation is something I below based on the drawing illustrated in more detail. The drawing shows in purely scheraatiöchösr! Way:

1 shows a vertical section through the central axis of the expansion compensation according to the invention

FIG. 2 shows a horizontal section through the central axis of the arrangement according to FIG. 1

3 shows a vertical section along the line A-B according to FIG. 1,

1 with the expansion body is referred to, which has the shape of a hose and its inner lining smoothly continuous is formed, i.e. is free of any undulations or other unevenness. On the outer circumference, this expansion joint has: body 1 a multiplicity of adjacent beads 1a, for the sake of simplicity in the two FIGS. 1 and 2 only some of these beads 1 a are indicated, so that the central region of the expansion body 1 also has these beads 1 a, which are there individually for the sake of clarity nen are not shown.

At one end of the expansion body 1, a flange 2 is provided, which In the connection 3 for one end of the pipe is stored "

Also at the opposite end is a flange 4! Which is mounted in the connection 5 for the other pipe end.

• With .._. .. Beaugsziffer 6th is a casing designated, f the

which aufaisst the expansion body 1. The end part 6a is cylindrical and serves as a guide for the connection *> which can slide on it.

The housing 6 has two opposite guide surfaces 6b (FIGS. 1 and 3) outside the end regions which is attached to the beads 1a of the tubular expansion body 1 apply tangentially in such a way that the expansion body 1 can move during the tube length change only in the space between these two guide surfaces 6b.

In the expansion body 1, a reinforcement insert 7 is provided, which can be, for example, a fabric or a wire spiral.

The mode of operation of the expansion compensator according to the innovation is as follows:

In Figure 1 is with a dashed line Initial position of the expansion body 1 indicated. If the pipeline in which the expansion compensator is mounted expands, for example, about hatred a, the overall arrangement assumes that position as shown in the figures of the drawing with a » continuous line is indicated. ;

Since the expansion body 1 Ic horizontal direction of the guide surfaces 6b is positively guided, it can only bulge out into the position indicated in FIG. Will now be the Expansion compensator correctly installed in the pipeline system, namely as shown in Figures 2 and 3 in detail, then 1 "water sacs" are avoided in the bulge of the expansion body. The expansion body 1 can also flow through easily cleaned.

Claims (3)

PROTECTION CLAIMS 1. Expansion compensator for pipelines, with a wrestling the tube length elastically absorbing and stored in a housing expansion body, which one end in the a pipe connection is stored and other ^ nds is received by the other pipe connection, which is slidably guided on the corresponding end of the housing, characterized in that the Expansion body (1) a hose with a smooth, continuous inner soffit and with beads lying next to one another on the outer circumference (1a), and that the housing (6) outside the end regions has two opposing guide surfaces (6b), which are tangentially applied to the beads (1a) of the expansion body (1) in such a way that the expansion body (1) during the pipe length change, only laterally in the space between these two guide surfaces (6b) can move. 2. Balancer according to claim 1, characterized in that a reinforcing insert (7), e.g. a fabric or a wire spiral, is provided in the expansion body (1). 3. Balancer according to claim 1 and 2, characterized in that the expansion body (1) is at the same time sealing of the connecting arm & doors. 732520825.10.73
