Definitions

  • the invention relates to a pipe coupling consisting of a first coupling part and a second coupling part, the coupling surfaces abut each other, and a coupling parts against each other sealing annular sealing element which is arranged in a groove of the coupling parts.
  • a pipe coupling or flange is known for example from the G 88 00 117 Ul.
  • the groove space is oversized so that it can accommodate the deformation volume of the seal under axial load.
  • Pipe distribution systems such as, for example, pivoting arc distributors, pipe fences, etc., which are required for producing germ-sensitive products such as food, beverages or pharmaceuticals, are equipped with detachable pipe couplings.
  • the couplings must be hygienic and easy to switch.
  • Object of the present invention is therefore to improve the known pipe coupling so that on the one hand when coupling no product to be conveyed can penetrate into the gaps between the sealing ring and groove and that on the other hand a simple automated coupling and decoupling is made possible by lateral displacement of the coupling parts.
  • the sealing element rests sealingly against the groove edges even in the uncoupled state under "diagonal" pretension, the groove space required for receiving the sealing element between sealing element and groove is sealed to the outside, so that no product penetrates into the gaps between the sealing ring and the groove and At the same time, it is possible to displace the two coupling parts transversely to one another with respect to their longitudinal axis without clamping the sealing material or pushing the sealing element out of the groove A part of the deformation volume can be received during coupling by the lumen of the coupling element carrying the sealing element This enables simple automated coupling in hygienically perfect conditions.
  • a sealed free groove space between the sealing element and the groove is provided in the decoupled state.
  • the free groove space takes up deformation volume, so that the lumen of the coupling part is less concentrated.
  • the diagonal connecting the groove edges with the longitudinal axis forms an acute angle of about 45 °.
  • the sealing element is designed as a whisker or as an O-ring. This leads to a simple and inexpensive solution.
  • the sealing element protrudes in the decoupled state with its end face or with a partial surface facing the adjacent coupling part beyond the coupling surface adjacent to the outer flank. It may be slightly convex shaped to favor lateral displacement of the coupling parts. Furthermore, the sealing element transverse to the groove edges connecting diagonals on a rear molding.
  • the rear molding supports the diagonal sealing against the two groove edges.
  • the rearward formation of the sealing element is formed as an annular pocket into which a clamping element can be inserted.
  • the clamping element can be used as an elastic O-ring or as a spring, such as For example, a metallic coil spring, be formed.
  • the first coupling part is designed as a male part with a circumferential clamping collar and the second coupling part as a female part, in which the male part with its clamping collar is lockable and displaceable transversely to the longitudinal axis.
  • the female part has two opposing clamping jaws, which engage behind the clamping collar of the male part in the coupled state.
  • the clamping jaws have a straight inner surface which tangentially touches the outer surface of the clamping collar.
  • the clamping jaws each have a pressure cam which press on the back of the clamping collar and press the coupling parts in the coupled state against each other.
  • the sealing element can be arranged not only in the male or female part but also in both coupling parts (back to tack).
  • the two coupling parts are secured by a pair of opposing parallel to the longitudinal axis guide pins against decoupling.
  • a rotary joint can be formed in a simple manner by the two coupling parts.
  • the coupling parts are formed as parts of a multi-tube distribution system.
  • Pipe couplings with a sealing element form the basis for multi-pipe distribution systems in which the empty pipe is switched. Switching takes place either by a linear movement or by a pivoting movement.
  • the distributors can have several inlets and outlets.
  • Pipe couplings each with a sealing element form the basis for multi-distribution systems in which the filled pipe is switched.
  • Blind covers on the stationary and mobile components of the manifold can close the free pipe ends.
