Definitions

  • the invention relates to a pipe seal for sealing a pipe joint between a first pipe having a sleeve and a second pipe having a spigot end, the pipe seal comprising an annular support portion and an annular sealing portion which is fixed to the support portion, wherein the Pipe seal rests in a groove of the first tube.
  • Pipe seals are annular seals which are placed between two pipes to seal the connection of the two pipes.
  • Pipe seals are available in various sizes, so that they are also suitable for pipe joints of pipes of different sizes.
  • a pipe seal which comprises an annular support and an annular sealing element.
  • the carrier is U-shaped and has two arms of different lengths.
  • the invention has for its object to provide a pipe seal that allows easier installation.
  • the support section has an indicator for determining the correct positioning of the pipe seal in the groove of the first pipe.
  • the indicator ensures that the pipe seal rests correctly in the groove of the first pipe, which can also be referred to as a socket pipe.
  • the indicator when inserting the second tube with the spigot end, the pipe seal is damaged due to incorrect insertion and / or the pipe seal does not seal properly due to incorrect insertion.
  • the indicator thus considerably simplifies the installation of the pipe seal.
  • the indicator and the support portion are integrally formed.
  • a simple production of the pipe seal is ensured with a few manufacturing steps.
  • the indicator on an axially projecting annular flange.
  • the flange thus extends coaxially with the longitudinal axis of the pipe seal.
  • the flange is in the installed state between the first tube and the second tube.
  • the flange projects beyond the first tube in the axial direction, that is to say the flange projects beyond the first tube at the end remote from the carrier section.
  • the indicator has an end projecting from the flange in the radial direction, annular collar.
  • the collar thus extends in the radial direction of the pipe seal, that is orthogonal to the axis of rotation of the pipe seal.
  • the collar can project beyond the first tube in the axial direction, so that it covers the end of the first tube to the outside.
  • the first tube may have another groove formed and arranged so that the indicator can engage in the groove.
  • the flange is thinner than the collar. This leaves enough room for the flange to extend between the first tube and the second tube.
  • a radially inner surface of the flange is bevelled radially outward at an end region.
  • the chamfering is intended to ensure that the spigot easily rests against the end region of the
  • Flange can be guided along.
  • the sealing portion of an elastomeric material in particular of TPE (thermoplastic elastomer) or EPDM (ethylene-propylene-diene rubber) produced.
  • An elastomeric material is particularly well suited for sealing.
  • the sealing portion advantageously has a hardness of from 30 IRHD to 40 IRHD (International Rubber Hardness Degree). In this hardness range, the sealing portion has particularly good sealing properties.
  • the support portion of a thermoplastic material in particular polypropylene (PP), made.
  • PP polypropylene
  • the sealing portion has a radially inwardly projecting contact arm, on which the inner surface of the sealing portion is provided.
  • the contact arm thus serves to abut against the second tube and the seal between the first and second tube.
  • the sealing portion on an axially projecting abutment arm which is adapted to abut against a surface of the groove of the first tube.
  • Fig. 1 is a sectional view of a first embodiment of the pipe seal according to the invention, while the second tube is inserted into the first tube, and
  • Fig. 2 is a sectional view of a second embodiment of the pipe seal according to the invention, while the second tube is inserted into the first tube.
  • FIGS. 1 and 2 each show a pipe seal 10 for sealing a pipe connection between a first pipe 24 and a second pipe 29.
  • the first pipe 24 has a sleeve 25.
  • the second tube 29 has a spigot end 30.
  • the pipe seal 10 has an annular support portion 1 1 and an annular sealing portion 19.
  • the support portion 1 1 may for example be made of a thermoplastic material, in particular of polypropylene (PP).
  • the sealing portion 19 is made of, for example, a thermoplastic elastomer (TPE) or an ethylene-propylene-diene rubber (EPDM) having a hardness of 30 IRHD to 40 IRHD (International Rubber Hardness Degree).
  • TPE thermoplastic elastomer
  • EPDM ethylene-propylene-diene rubber
  • the pipe seal 10 is located in a groove 26 of the first tube 24 a.
  • the sealing portion 19 is integrally formed with the support portion 1 1.
  • the support portion 1 1 has an outer surface 12 and an inner surface 13.
  • the sealing portion 19 has an outer surface 20 and an inner surface 21.
  • the outer surfaces 12, 20 abut against a surface 27 of the groove 26 of the first tube 24.
  • the inner surfaces 13, 21 are each formed to contact a surface 31 of the second tube 29.
  • the support section 1 1 has an indicator 14.
  • the indicator 14 serves to determine the correct positioning of the pipe seal 10 in the groove 26 of the first tube 24. In case of incorrect positioning of the pipe seal 10 in the groove 26, the pipe seal 10 could be wedged or twisted, or it could by inserting the spigot end 30 are damaged. This is prevented by the indicator 14.
  • the indicator 14 has an axially protruding, annular flange 15. The flange 15 extends parallel to the axis of rotation of the pipe seal 10. In the assembled state, the flange 15 extends between the first pipe 24 and the second pipe 29th
  • the flange 15 projects beyond the first tube 24 at the end facing away from the support portion 1 1 end.
  • annular collar 18 is provided on the flange 15 a projecting in the radial direction.
  • the collar 18 extends in the radial direction of the pipe seal 10, that is orthogonal to the axis of rotation of the pipe seal 10.
  • the collar 18 projects beyond the first pipe 24 in the axial direction, so that it covers the end of the first pipe to the outside.
  • the first tube 24 may have another groove formed and arranged so that the collar 18 can engage in this groove.
  • the flange 15 is thinner than the collar 18, since this is in the assembled state between the first tube 24 and the second tube 29.
  • a radially inner surface 17 of the flange 15 is bevelled radially outwardly at an end region 1 6.
  • the chamfer can accordingly extend in particular so that it coincides with the spigot end 30 of the second tube 29.
  • the spigot end 30 may be guided along the tapered surface 17 such that the spigot end 30 can not tilt or twist the tube seal 10.
  • the indicator 14 has a flange 15 without collar.
  • the flange 15 projects beyond the first tube 24 on the end region 1 6 remote from the carrier section 11 and is thus visible in the installed state of the tube seal 10.
  • the sealing portion 19 may have a radially inwardly projecting contact arm 22 on which the inner surface 21 of the sealing portion 19 is provided. Since the contact arm 22 protrudes inward, this can better abut the surface 31 of the second tube 29 and thus better seal the tubes 24, 29 against each other.
  • the sealing portion 19 has an axially projecting abutment arm 23.
  • the abutment arm 23 may rest against a surface 28 of the groove 26 of the first tube. As a result, the pipe seal 10 is compressed more easily, thus allowing a better seal.
  • the pipe seal 10 is inserted into the groove 26 of the first pipe 24.
  • a lubricant is uniformly applied.
  • the second tube 29 is inserted into the first tube 24 along the insertion direction.
  • the tube seal 10 is compressed between the groove 26 of the first tube 24 and the second tube 29 in order to bear tightly against the two tubes 24, 29.
  • the assembly of the pipe seal 10 is simplified.
  • the indicator 14 ensures that the pipe seal 10 is correctly positioned. Thus, it can be prevented that the pipe seal 10 is not adequately sealed or even damaged by improper insertion into the first tube 24.
