Definitions

  • the invention relates to a repair kit for the sealing of delivery lines, in particular thick matter or concrete delivery lines.
  • Leakage in delivery lines is a known problem. With delivery lines, particles that are in the media to be pumped lead to abrasive wear on the lines, which can ultimately lead to a leak. The leaks are difficult to spot, i. e.g. on a construction site, seal. In concrete delivery lines, sometimes very high pressures prevail (more than 80 bar). The seals must withstand these pressures and must not come off the lines due to the pressures. It is therefore an object of the invention to provide a repair kit, can be sealed by the leaks in lines quickly, easily and inexpensively.
  • the repair set according to the invention for the sealing of delivery lines has at least one sealing element, wherein the sealing element is monolithic or formed as a composite component and has a base body and a support layer.
  • the repair set is characterized in that the base body is dimensionally stable and the support layer has at least two layers, a first and a second layer, the first layer being arranged between the base body and the second layer.
  • the repair set according to the invention has the advantage over the prior art that leaks can thereby be sealed quickly, safely and cost-effectively, and in particular "on site", eg on a construction site where no special tool or repair material is present
  • the sealing element can be attached to the delivery line via a leak to be sealed with a commercially available coupling (also referred to as a pipe clamp or shell clutch), as routinely, for example, for connecting line sections of the
  • a commercially available coupling also referred to as a pipe clamp or shell clutch
  • the sealing element can be designed in one piece or monolithically or in several parts, preferably in two parts, as a composite component
  • the multi-part structure is particularly advantageous if the leak on the line is so great that several couplings are present must be clamped on the line so that the leak can be covered.
  • a continuous support layer is applied to the leak.
  • At least one main body is used to transfer the closing forces to the support layer in the individual clutches.
  • a plate which preferably consists of metal, may be arranged. If several basic bodies are present, then the plate ensures, among other things, a stable bridging of the small space between the basic bodies. Overall, an improved or increased contact force can be achieved by the plate, whereby the sealing of the leak is improved.
  • strength-increasing components or additives such as, for example, steel reinforcements, Kevlar, hard plastics or the like, can be incorporated into the body.
  • the first and second layers of the overlay layer may have different hardnesses. Ideally, the first layer has a greater hardness than the second layer. As a result, the sealing of the leak can be ensured. Due to its hardness and the associated resistance, the first layer forwards the contact pressure generated by the coupling to the layer below it. The underlying layer adapts well due to a lower hardness of the shape of the line.
  • the first layer has a Shore A hardness of approximately between 80 and 95. Ideally, the Shore A hardness is about 85. With such a Shore A hardness, the layer has a relatively high hardness and resistance such that the contact force generated by a clutch is absorbed by the first layer and transmitted to the underlying second layer can. As a result, the contact pressure of the second layer is optimized for the pipe.
  • the second layer preferably has a Shore A hardness which is approximately between 50 and 60. Ideally, the Shore A hardness is about 55. With such a Shore A hardness, the layer has a good deformability, so that it can be ensured that the sealing element optimally applies to the line and thus securely seals the leak.
  • the support layer of the sealing element preferably has a third layer.
  • the third layer adjoins the second layer and is in the mounted state of the repair kit to the line.
  • the third layer has a hardness of Shore A 70 to 80, preferably about Shore A 75 on.
  • the overlay layer is reinforced by the use of the third layer, it becomes stiffer.
  • the first layer preferably has a thickness of more than 10 mm, in particular more than 12 mm. As a result, a sufficiently high rigidity can be ensured.
  • the second and the third layer preferably have only a thickness of a few millimeters. Preferably, the thickness is between 2 and 3 mm.
  • the overlay layer may extend beyond the dimensions of the main body. This is particularly advantageous when the leak is in a weld or at a kink of the line. In these areas, a secure attachment of a shell clutch is difficult. So that the support layer is pressed as firmly as possible on the line, is advantageously between the body and the support layer nor a plate which is preferably dimensionally stable, arranged.
  • a fastening means is arranged on the sealing element.
  • the fastening means serves to fasten the sealing element to a coupling or a retaining element.
  • the attachment is ideally carried out by means of a magnet or an adhesive connection. But also a frictional connection is conceivable.
  • the fastening means is arranged on the base body.
  • the sealing element can also be held in the retaining element or in the coupling by positive locking.
  • the sealing bead is an annular, i. the sealing bead surrounding the leak sealing edge. Due to the sealing bead, the pressure forces act on a smaller area, which results in a higher surface pressure and this leads to a better seal.
  • the repair kit can be installed in conventional couplings.
  • a spacer can be arranged on the sealing element.
  • the existing coupling is a matching spacer on the Attached sealing element.
  • the spacer cohesively, in particular by an adhesive layer, connected to the sealing element.
  • the spacer can be arranged on the base body.
  • the repair kit comprises at least one coupling, preferably in the form of a shell coupling or a pipe clip, as mentioned above.
  • a coupling typically has two in the closed state, a circular opening for the delivery line limiting coupling shells, which are pivotable at one end via a joint about an axis of rotation to the circular axis hinge axis against each other, wherein the one coupling shell at its opposite end of the hinge a closing element and the other Clutch shell has at its opposite end of the hinge a cooperating with the closing element closing mechanism.
  • the locking mechanism may e.g.
  • the closing element form-fitting comprehensive and have the coupling shells at its opposite the joint separation point against each other pulling hook, which is releasable during the opening operation of the closing element.
  • the closing hook can be coupled to an over-center lever.
  • the sealing element with its support layer on the leaking point of the delivery line and is pressed by the coupling in the closed state with high contact pressure on the line, so that the leak is securely sealed.
  • the coupling shell of the coupling takes the sealing element at least partially, preferably the base body in on.
  • the support layer of the sealing element can be wider than the cross section of the coupling shell. This is e.g. then advantageous if the leak is in a weld or at a bend in the pipe, i. at a point above which the shell clutch can not be placed directly.
  • the repair set in addition to the coupling and the sealing element still has a spacer which substantially corresponds to the dimensions of the sealing element.
  • a Spacer increases the contact pressure of the sealing element on the tube and improves the sealing of the leak.
  • the spacer as well as the sealing element is at least partially disposed in the shell clutch and is preferably offset by 180 ° (with respect to the line axis) to the sealing element on the sealed line. As a result, the pressure distribution on the line can be made uniform.
  • a further sealing element as a spacer.
  • the overlay layer may be wider than the cross section of the coupling. This is particularly conceivable if between the dimensionally stable base body of the sealing element and the soft overlay layer, a correspondingly dimensioned metal plate is inserted.
  • the contact pressure of the sealing surface can be increased overall by constructive measures (gusset plates, diagonal struts, or the like). If the leak is particularly large, then the repair set may have a plurality of clutches, which are arranged side by side along the line course.
  • the sealing element may be formed as a composite component. It has at least as many basic bodies as couplings are used. Furthermore, the sealing element in this embodiment, a single, continuous support layer which connects the base body together.
  • a metal layer can be arranged between the base bodies and the support layer.
