Elastic connection for the conduction of flowable media

The innovation concerns an elastic connection for the conduction of flowable media that are switched on in pipelines or can be connected directly to machines or devices.

According to the innovation, the elastic connection consists of a uniform hollow molded body made of soft rubber or a similar highly elastic material, the Ends are designed as flat clamping flanges, between which a tubular part extends, the wall of which is partially arched outwards like folds. The cross-section of the elastic connection is based on that respective application. It is preferably round in cross-section and with a square cross-section in different Large manufactured, the version with a round cross-section for introduction into pipelines to the line of liquids is used, while the version with a square cross-section is used on fans or in fan ducts is inserted and is used in similar applications

Duroh the elastic connection is, as there is no bridging Metal parts are present, a noise and

Ersohtttterungsdämmung achieved in the sense that the Transmission of disruptive forces is prevented · The clamping flange attached to the ends of the molded rubber body allow a simple detachable connection with the splashing of the pipe ends, whereby the intermediate layer is special There is no need for soft diaing, since the puddles themselves are elastic are · So that a tight connection is created at these points, loose rings made of solid materials, preferably made of metal, which rest on the clamping flanges and have approximately the same Durohmesser. This one Rings do not have a fixed connection, they do not interfere with or complicate the production of the rubber molded body in any catfish · you can be undivided as the elastic rubber flanges can be pulled through them. In many In some cases, however, it will be advantageous to produce these rings in a split design in order to further simplify handling. The elastic connectors are manufactured with different nominal widths, so that each one Connector can be chosen whose clear passage opening is the same or slightly larger than that of the connecting pipes or connecting flanges of the machines, so that there is no deterioration in the flow conditions results.

Due to their special shape, the elastic connecting pieces are still so elastic that they can both

Compensate for considerable changes in the length of the pipelines, as well as center and angle bearings of the same can.

Also in the production can only be made of rubber the elastic connection already absorb considerable internal and external pressures as a result of its favorable shape. If the pressures are to be increased further, fabric inserts can also be used to reinforce be incorporated into the molded rubber body.

Pipe ends 4 are in contact. The connection between these Splitting is done in a known manner by means of screw bolts 5 · To achieve a good seal, ordinary Washers or sioh extending over the entire circumference of the pipe connection, but expediently split washers 6 used. On the clamping flanges 2 Bohliesat each time a strong cylindrical part 1 · on · between these two cylindrical parts Parts 1 · there is a fold-like piece 7, which after the embodiment according to Pig. 1 shows a U-shaped cross section and is geriohtet outwards, so the clear Durohmesser of the connection, that of the pipe ends 4 corresponds, is not constricted ο

This part ¹¹ can be kept shorter in its axial length, so that one piece of folds 7 'is almost immediately adjacent to the next Fold piece 7 'attaches to it.

Even with the arrangement of a gap piece, the elasticity of the connection is so great that this design is sufficient in almost all cases and is by far preferable because of its great simplicity and short overall length.
