Definitions
- the invention relates to a sealing arrangement of a pipe connection, in particular jacking pipe connection, consisting at least of:
- first and second component to form an annular gap, wherein in particular the first component is a spigot end and the second component is a sleeve with a steel sleeve;
- a first and second sealing ring made of elastomeric material, which are arranged contactlessly at a distance from one another and thereby seal the annular gap;
- a circumferential test room which is located between the two sealing rings and to which at least one line is connected, wherein pressure can be built up by means of an injectable test medium, and setpoint deviations with regard to the sealing performance can also be detected by means of a measuring device.
- a generic sealing arrangement with an integrated test device is known for example from the published patent application DE 39 33 873 A1.
- the first sealing ring is designed as a rolling ring and the second sealing ring as a compression seal with a hollow chamber structure. If leaks were found using the test facility, the two sealing rings often had to be replaced. Another possibility was to press the test space using a sealing compound using the old sealing rings. A later check was then no longer possible.
- the object of the invention is to provide a sealing arrangement in which a leak test can take place at any time. Furthermore, a subsequent increase in sealing performance or a re-sealing should be carried out without replacing the sealing rings be guaranteed in the event of a leak. In addition, the sealing rings are to be prevented from moving in the axial pipe direction.
- Each sealing ring has a first and a second sealing area, the first sealing area being provided with a circumferential fastening seat to the first component and also being connected to a likewise circumferential activation chamber, while the second sealing region makes the sealing contact with the second component;
- each sealing ring is connected to at least one line through which a medium flows for the activation or post-activation of the sealing rings;
- test medium and the medium for activation or post-activation are continuously flowable.
- FIG. 1 shows a sealing arrangement with two activatable sealing rings and a test room
- Figure 2 shows a sealing ring in which the activation chamber is designed as a profile foot with an integrated single chamber, in the context of an integral overall assembly of the sealing ring.
- FIG. 3 shows a sealing ring according to FIG. 2 with additional anchoring feet
- FIG. 4 shows a sealing ring with a tubular body
- 5 shows a sealing ring with a tubular body, the sealing ring being additionally equipped with anchoring feet
- FIG. 6 shows a sealing ring with a tubular body which is reinforced and forms a sandwich system with the sealing ring
- Fig. 7 shows a sealing ring which is designed as a piston seal.
- Fig. 1 shows a sealing arrangement 1, comprising a first component 2 made of concrete in the form of a pointed end, a second component 3, which is designed as a sleeve with a steel sleeve, and two sealing rings 5 and 6 made of elastomeric material, which seal the annular gap 4 in a sealing manner.
- the two sealing rings 5 and 6 are arranged in a contactless manner at a distance from one another (series connection), to be precise with the formation of a test space 9 to which at least one line 10, which runs within the tip end, is connected.
- a pressure can be built up in the test room by means of an injectable and permanently flowable test medium, and setpoint deviations can also be detected by means of a measuring device.
- Each sealing ring 5 and 6 has a first and second sealing area A and B.
- the sealing area A sits in a circumferential groove.
- the activation chamber 7 comprises a profile foot with an integrated single chamber, in the context of an integral overall assembly with the first sealing area A, the profile foot being arranged within a further groove. In this way, an effective fastening seat for the sealing area A is ensured, which in turn forms an integral composite with the sealing area B in the form of a wedge seal.
- each sealing ring is connected to at least one line 8, which likewise runs within the tip end and through which a permanently flowable medium for the activation or post-activation of the sealing rings flows.
- the sealing area A of the sealing ring 5 according to FIG. 2 is not seated in a groove.
- the only fastening seat here is the profile foot with the activation chamber 7.
- the width of the sealing area A is larger than the width of the profile foot, which is arranged approximately in the center with respect to the sealing area A.
- the sealing area A of the sealing ring 11 has two anchoring feet 12, the activation chamber 7 being arranged between these two anchoring feet.
- the activation chamber 15 and 18 is a tubular body (activation tube) which is connected to the line 8 which runs through the tip end 2. While the sealing area A of the sealing rings 13 and 17 (FIGS. 4, 6) sits in a groove of the tip end, the sealing area A of the sealing ring 16 (FIG. 5) is equipped with two anchoring feet 12. A special construction is provided for the sealing ring 17 (FIG. 6), the tubular body being reinforced and being arranged between the two sealing areas A and B, with the formation of a sandwich system. Furthermore, the line 8 runs here centrally through the sealing area A and from there through the tip end 2.
- the sealing area A of the sealing ring 19 is seated in a groove of the tip end 2, the activation chamber 20 being a groove space which is formed by the sealing area A being raised inside the groove in the form of a piston. Because of the piston effect, the sealing ring 19 can also be referred to as a piston seal.
- the medium for activation or post-activation is in direct contact with the sealing ring. Due to the sealing lips 22 within the two groove flanks, however, the medium cannot emerge laterally from the groove.
- the sealing area B is designed here as a lip seal.
- test medium and the medium for activation or post-activation are liquid and / or gaseous.
- the test medium is in particular liquid, in particular in the form of water.
