Definitions
- the invention relates to a movable Rchrtechnisch between relatively movable connection parts of a hydraulic system, in particular between an input port of a suction valve of a positive displacement pump and an output port of a suction manifold of this pump.
- corrugated tubes or tubes are problematic because the beads in the interior of the corrugated tube or tube fill in a short time with sediments, so that the mobility of the corrugated tube or tube is no longer exist and the corrugated tube or the corrugated sheet behave practically like a rigid part and due to the relative movements between the connecting parts are destroyed in the shortest possible time.
- This object is achieved by two telescopically with formation of an axial annular gap nested tubes whose free end edges are pressed sealingly against annular mating surfaces of the connecting parts, wherein the diameter of the formed between the front ends and the mating surfaces sealing contact zone is smaller than the diameter of the annular gap.
- the invention is based on the general idea to provide a telescoping tube assembly between the relatively movable connection parts whose free ends are in constant adhesion with the associated mating surfaces of the connecting parts. It is inventively provided to exploit the hydraulic internal pressure in the pipes for the frictional connection. Since the annular gap has a larger diameter than that between the front ends and The hydraulic internal pressure seeks to push the telescopically inserted into each other tubes apart by increasing the axial of the distance of their free front ends of the Gegenflädien the Ansdlussmaschine formed sealing contact zones. In this way, sufficient pressure forces for secure sealing are always ensured at the connection points.
- End edges have the shape of an annular section of a spherical cap, while the mating surfaces has conical or conical shape. In this way, an advantageous circular contact between the front ends and the mating surfaces is ensured.
- a compression spring is clamped in the form of a helical compression spring between an outer flange on a pipe and the facing end or an outer flange of the other tube. This ensures a certain minimum force between the free ends of the movable pipe and the mating surfaces of the connecting parts regardless of the hydraulic pressure within the pipes. Even with business interruptions so the movable pipe has a tight fit.
- the pipe can be arranged within a arranged between the connecting parts corrugated tube or pipe.
- About a Auskss formed between the corrugated pipe and the tubes arranged therein annulus may optionally be determined whether leakage fluid has penetrated into the annulus and parts of the movable pipe should be replaced.
- the annular gap is sealed by sealing rings of Ekstomermaterial and metal, wherein the Ekstomerringe, seen from the tube inner end of the annular gap, preferably are arranged axially behind a metal ring.
- This arrangement offers the advantage that the metal ring, if appropriate, keeps particles that have penetrated the annular gap away from the conveyed suspension from the ecstasy rings, so that their service life is considerably prolonged.
- Fig. 1 shows a Axialsdinitt a pipe according to the invention between two mutually movable connection parts and
- Fig. 2 is a similar representation, but with the connecting parts have moved relative to each other due to relative movements transversely to the tube axis.
- a movable pipeline 3 is arranged between two connecting parts 1 and 2 of a hydraulic system, for example a coal hydrogenation plant, which move relative to one another during operation.
- a hydraulic system for example a coal hydrogenation plant
- This consists of two to form an axial annular gap 4 telescopically nested tubes 5 and 6, the facing away from each other free end edges 7 have the shape of an annular section of a spherical cap.
- the end edges 7 are stretched in a manner shown below against the annular mating surfaces 8 on the connection parts 1 and 2, so that there is a frictional connection.
- the mating surfaces 8 have the shape of a jacket of a truncated cone, so that between the spherical end edges 7 and the conical mating surfaces 8 is given a circular, sealing contact zone, even if the connection parts 1 and 2 of FIG. 2 due to relative movements relative to each other assume a relative to each other laterally offset position.
- the mating surfaces 8 could be formed as compared to the end edges 7 gegen Dermate spherical surfaces, so that the mating surfaces and the end edges rest on a wide annular surface each other. From the viewpoint of ease of manufacture and high pressure forces in the contact area, however, the embodiment described above with annular contact of the end edges and the counter surfaces 7 8 is advantageous.
- the inner diameter of the tube 6 is corresponding to the
- Outer diameter of the tube 5 is increased to a degree, wekhes greater than the diameter D of the annular contact zones between the end edges 7 and the mating surfaces 8. This ensures that the hydraulic pressure of the pipe passing through the medium pipes 5 and 6 under pressure to the Seeks to push opposing surfaces 8 apart. As a result, so the hydraulic pressure always ensures that the end edges 7 are stretched with sufficient sealing action against the mating surfaces 8.
- a helical compression spring 10 is clamped between an outer flange 9 on the tube 5 and the facing end edge of the tube 6, which also at vanishing hydraulic pressure for a secure fit of the end edges 7 at the Gegenflädien 8 provides.
- the sealing ring 11 is formed in the manner of a piston ring on a piston of an internal combustion engine and is made of metal, while the sealing rings 12 consist of a Ekstomermaterial.
- the primary purpose of the metallic sealing ring 11 is to protect the sealing rings 12 from the attack of abrasive solid particles when the pipeline 3 is traversed by a suspension, for example, coking sludge.
- the sealing rings 12 seal the annular gap 4 against a passage of the carrier liquid of the suspension.
- the pipe 3 may be disposed within a connecting pipe 1 and 2 connecting corrugated pipe 13, optionally in the annulus between the corrugated pipe 13 and the pipe 3 penetrated hydraulic medium via a bore 14th can be detected and removed in a connected to the corrugated tube 13 flange on the connector part 1.
