Installation element of an installed packing

A first and second installation element of an installed packing for the exchange of material and/or heat between gases and liquids, the installation elements each comprising a body having a defined thickness and one of the installation elements having a peg projecting from the body and the other of the installation elements having a recess extending through the entire thickness of the body such that the peg is received in the recess for locking the two installation elements together, comprising:

• two ring gap segments allocated to the recess, the ring gap segments extending through the entire thickness of the body of the installation element,
• two locking shoulders being fashioned on the peg to project radially outwardly from the peg, each locking shoulder having an angular extent of less than 90° such that a peripheral portion of an end of the peg between the locking shoulders has no projections extending radially beyond a surface of the peg, the pegs being positioned at a 180° distance from each other in the circumferential direction, each locking shoulder having at least one tapered face on an insertion side of the locking shoulder,
• the body having an opening therethrough directly axially in alignment with each locking shoulder, and
• the ring gap segments, and the two locking shoulders, being situated so as to correspond to one another in such a way that each time the peg is pushed through the recess, material in an edge area of the recess is displaced into the ring gap segments by means of the two locking shoulders, and when the peg has been completely pushed through the recess, the material in the edge area surrounding the recess returns to its initial position,
• wherein said material in the edge area of the recess that is displaceable into the ring gap segments by means of a locking shoulder comprises at least two tapered sections on the insertion side of the recess in positions to engage with the two locking shoulders on the peg, the shape of said tapered section substantially corresponds to the shape of the tapered face of the locking shoulder, and the tapered section serves as a guide surface for said locking shoulder when the peg carrying said locking shoulder is inserted into said recess.

An installation element of an installed packing for the exchange of material and/or heat between gases and liquids, the installation element comprising a body having a defined thickness and having pegs projecting from the body and recesses provided in the body for locking with respective recesses and pegs of at least one further identical installation element, comprising:

• two ring gap segments allocated to each of the recesses, the ring gap segments extending through the entire thickness of the body of the installation element,
• two locking shoulders being fashioned on each peg to project radially outwardly from the peg, each locking shoulder having an angular extent of less than 90° such that a peripheral portion of an end of the peg between the locking shoulders has no projections extending radially beyond a surface of the peg, the pegs being positioned at a 180° distance from each other in the circumferential direction, each locking shoulder having at least one tapered face on an insertion side of the locking shoulder,
• the ring gap segments each having an angular extent greater than the angular extent of each locking shoulder,
• the body having an opening therethrough directly axially in alignment with each locking shoulder, and
• the ring gap segments, and the two locking shoulders, are situated so as to correspond to one another in such a way that each time the peg is pushed through the recess, material in an edge area of the recess is displaced into the ring gap segments by means of the two locking shoulders, and when the peg has been completely pushed through the recess, the material in the edge area surrounding the recess returns to its initial position,
• wherein said material in the edge area of the recess that is displaceable into the ring gap segments by means of a locking shoulder comprises two tapered sections on the insertion side of the recess in positions to engage with the two tapered faces of the locking shoulders on the peg, the shape of said tapered section substantially corresponds to the shape of the tapered face of the locking shoulder, and the tapered section serves as a guide surface for said locking shoulder when the peg carrying said locking shoulder is inserted into said recess.
