Definitions

  • the invention relates to a coupling device which has for a connection between tubular or tubular conduits forming a passage for a medium connecting body on one line and a flange disposed on the other end of the flange, which by anchor bolts which are anchored to the connector body with this is braced, wherein between flange and connecting body, a seal assembly is provided with a radial seal which is disposed between an annular surface on the flange and an annular body located on the terminal surface, which form concentric sealing surfaces.
  • Coupling devices of this type are known. Although such coupling devices are characterized by a relatively simple design and ease of assembly, because during assembly, the radial seal in the form of one or more sealing rings may be fixed to the associated annular surface, so that when bringing together
  • the object of the invention is to provide a coupling device of the type in question, which enables a reliable connection in lines which carry pressure media with a high pressure level.
  • a significant feature of the invention is that a second seal arrangement with at least one axial seal is present at a spatial distance from the seal having a radial seal.
  • a second seal arrangement with at least one axial seal is present at a spatial distance from the seal having a radial seal.
  • the arrangement is such that the flange forms at its end associated with the connecting body an end face which extends in the direction of the flange longitudinal axis normal radial plane from the circular peripheral edge of the flange up to a longitudinal axis coaxial extension thereof ben, wherein first sealing arrangement on the extension and the second sealing arrangement are located on the end face.
  • first sealing arrangement on the extension and the second sealing arrangement are located on the end face.
  • the arrangement can be advantageously made so that the end face of the flange is clamped against a parallel to its end face of the connecting body, which latter forms a sealing surface for a sealing ring for the second seal assembly, which sits in a machined in the end face of the flange and groove seals against the face of the terminal body serving as the second sealing surface.
  • the arrangement can furthermore be made such that a recess, which receives the extension of the flange and is coaxial with the longitudinal axis, is provided on the connection body, which on the inside forms the one annular surface which serves as the one sealing surface for the first sealing arrangement.
  • this annular surface on the inside of the recess can be formed on the recordable in the recess of the connecting body extension as a flange-side sealing surface of the first seal assembly sealing annular surface on which seals a radial seal forming sealing ring.
  • a particularly simple assembly allows an embodiment in which the formation of the flange-side annular surface in the outer periphery of the extension, a radially recessed annular groove is incorporated for serving as a radial seal seal.
  • the radial seal for the assembly process is particularly reliable secured to the extension of the flange.
  • the measured width in the axial direction of the annular groove of the extension is sized larger than the axial dimension of the sealing ring.
  • the axial length of the extension of the flange is slightly smaller than the axial length of the recess of the connector body, so as to ensure that when tightening the flange on the connector body, only the end faces of flange and connector body are supported against each other.
  • FIG. 1 is a perspective oblique view of an embodiment of the coupling device according to the invention and Fig. 2 shows a comparison with FIG. 1 enlarged and slightly simplified simplified drawn longitudinal section of the embodiment according to the section line A-A of Fig. 1st
  • the illustrated in the drawing embodiment of the coupling device according to the invention is provided for the connection of lines that carry a pressure medium, such as a hydraulic fluid.
  • a metallic first line is denoted by 1
  • a flange 3 is located, which has a circular peripheral edge 5.
  • the connectable via the coupling device with the first line 1 second line, which is not shown in the drawing, is screwed at its coupling end with a metallic connector body 7.
  • This has the form of a hollow cylinder on the whole, which is provided for this screw with an external hexagon 9.
  • a concentric to the longitudinal axis 1 passage 13 corresponds in its dimensions to the inner diameter of the line to be connected 1.
  • End bil- det the connector body 7 has an end face 15 in a normal to the axis 1 1 radial plane.
  • a clamping ring 17, are anchored in the clamping screws 19 with their shafts, is screwed onto the connector body 7 so that it forms with its end face 21 a co-planar continuation of the end face 15 to the outside.
  • clamping screws 19 are based with their provided with hexagon screw heads 23 on clamping jaws 25 which are formed as a metallic forging or pressing semi-annular, each jaw 25 is penetrated at each end of a clamping screw 19, so that four clamping screws 19 as Clamping device are available.
  • Each jaw 25 has on its radially inner side a step surface 27 which engages over the flange 3 of the line 1 from the peripheral edge 5 ago.
  • a flange-side end face 29 which extends radially inward from the peripheral edge 5, up to a circular cylindrical extension 31 which projects concentrically to the axis 1 1 axially.
  • the extension 31 extends into a coaxial depression 33, which forms an extension of the passage 13 in the connection body 7.
  • the axial length of the extension 31 is slightly smaller than the axial depth of the recess 33, so that the end of the extension 31, when the coupling device is assembled, as shown in the figures, at a small distance from the bottom 35 of the recess 33 is located.
  • the recess 31 forms with its inner side, ie with the wall, which adjoins the radially inner end of the end face 15, an annular surface 37 as the one sealing surface of a radial seal assembly 39, the second sealing surface by a radially recessed into the extension 31 incorporated Ring groove 41 is formed, in which a sealing ring 43 is received.
  • a second sealing arrangement in the form of an axial sealing arrangement designated by 45 is arranged such that it seals the flange-side end face. che 29 seals against the end face 15 on the connector body 7 when flange 3 and connector body 7 are clamped together, as shown in the figures.
  • annular groove 47 for a sealing ring 49 serving as an axial seal is incorporated into the flange-side end face 29 in the central region between peripheral edge 5 and extension 31, which is compressed axially in the assembled state and thus under sealing force on the end face 15 is applied.
  • the sealing ring 43 of the radial seal assembly 39 is also dimensioned in relation to the depth of the annular groove 41 so that it rests with radial sealing force on the annular surface 37 and the bottom of the annular groove 41.
  • the axial length of the annular groove 41 is dimensioned such that under pressure loading of the sealing ring 43, wherein pressure medium from the end of the extension 31 passes through the gap between the outside of the extension 31 and inside of the recess 33 into the annular groove 41, the sealing ring 43 against the flange 3 adjacent end of the annular groove 41 moves and is pressed under deformation to the transition gap between the annular groove 41 and the inside of the recess 33.
  • the sealing rings used are made of an elastomeric material and are designed in the manner of O-rings.

Abstract

Dispositif d'accouplement qui, pour un assemblage entre des conduites (1) sous forme de tuyaux souples ou de tubes, présente un corps de raccordement (7) formant un passage (13) pour un fluide sur une des conduites et un collet (3) disposé terminalement sur l'autre conduite (1). Le collet (3) peut être assemblé par serrage au corps de raccordement (7) par des vis de serrage (19) qui sont ancrées sur ce dernier. Un ensemble de joint d'étanchéité (39) doté d'un joint d'étanchéité radial (43) est présent entre le collet (3) et le corps de raccordement (7) ; il est disposé entre une face annulaire (41) sur le collet (3) et une face annulaire (37) se trouvant sur le corps de raccordement (7), qui forment des surfaces d'étanchéité mutuellement concentriques. Selon l'invention, un deuxième ensemble de joint d'étanchéité (45), qui présente au moins un joint d'étanchéité axial (49) et se trouve à distance spatiale du premier ensemble d'étanchéité (39), est présent entre le collet (3) et le corps de raccordement (7).
