Sealing element
The present disclosure relates to a sealing element for a pressed connection that includes an essentially ring-shaped body constructed of elastic material. Also included is at least one sealing edge formed on an interior side and an exterior side of the ring-shaped body. At least one cutting element is embedded in the ring-shaped body and has a cutting edge. The cutting edge is configured to be moved out of the ring-shaped body during a pressing-together of the pressed connection. The present disclosure further relates to a pressed connection for plumbing fixtures. The pressed connection includes a connection piece adapted to have a receiving device constructed therein and configured to receive a pipe end. The connection device is further configured to be pressed together into the pressed connection. Further included is a sealing element arranged in the receiving device, the sealing element comprised as described above.
1. A sealing element for a pressed connection, the sealing element comprising:
an essentially ring-shaped body constructed of elastic material;
at least one sealing edge formed on an interior side and an exterior side of the ring-shaped body;
at least one cutting element embedded in the ring-shaped body, the at least one cutting element having only a single cutting edge embedded in the ring-shaped body, and the cutting edge configured to be moved out of the ring-shaped body during a pressing-together of the pressed connection; and
wherein the at least one cutting element has a V-shaped cross-section, the single cutting edge being radially inward-directed, and with respect to a radial direction, the at least one cutting element including two diagonally outward-extending legs.
2. The sealing element according to claim 1 , wherein the cutting edge is arranged on an interior surface of the sealing element.
3. The sealing element according to claim 1 , wherein the at least one cutting element has a curved construction.
4. The sealing element according to claim 1 , wherein the at least one cutting element extends in a radial direction from an inner surface to an outer surface of the sealing element.
5. The sealing element according to claim 1 , wherein at least one of the two legs reaches to a surface of the sealing element.
6. The sealing element according to claim 1 , further including a sealing ring arranged adjacent to the at least one cutting element, which sealing ring is connected by a web with a section of the sealing ring in which the at least one cutting element is embedded.
7. The sealing element according to claim 1 , wherein the at least one cutting element is made of steel.
8. The sealing element according to claim 1 , wherein the at least one cutting element has an asymmetrical cross-section.
9. The sealing element according to claim 1 , wherein the at least one sealing edge surrounds the ring-shaped body and is continuous thereon.
10. The sealing element according to claim 1 , wherein the elastic material of the ring-shaped body is made of rubber.
11. The sealing element according to claim 1 , wherein the at least one cutting element includes a plurality of cutting elements.
12. The sealing element according to claim 11 , wherein the plurality of cutting elements are distributed over a circumference of the sealing element.
13. The sealing element according to claim 11 , wherein each of the plurality of cutting elements extends in a radial direction from an inner surface to an outer surface of the sealing element.
14. The sealing element according to claim 11 , wherein the plurality of cutting elements have a V-shaped cross-section.
15. The sealing element according to claim 11 , wherein the plurality of cutting elements have an asymmetrical cross-section.
16. A pressed connection for plumbing fixtures, comprising:
a connection piece adapted to have a receiving device constructed therein and configured to receive a pipe end, the connection piece further configured to be pressed together into the pressed connection;
a sealing element arranged in the receiving device, the sealing element comprising a ring-shaped body, at least one sealing edge formed in an interior side and an exterior side of the ring body, and at least one cutting element embedded in the ring-shaped body, the at least one cutting element having only a single cutting edge embedded in the ring-shaped body and the cutting edge configured to be moved out of the ring-shaped body during the pressing-together into the pressed connection; and
wherein the at least one cutting element has a V-shaped cross-section, the single cutting edge being radially inward-directed, and with respect to a radial direction, the at least one cutting element including two diagonally outward-extending legs.
17. The pressed connection according to claim 16 , wherein the at least one cutting element includes a plurality of cutting elements distributed over a circumference of the sealing element, and the cutting edge of each cutting element is arranged on an interior surface of the circumference.
