Definitions

  • the invention relates to a coupling for connecting a coupling housing to a nipple, which are provided for feeding a cryogenic medium, in particular LNG to a vehicle tank, wherein a hand lever is pivotably arranged at the coupling housing for connecting.
  • the known couplings require high assembly expenditures.
  • the plugging/pushing connection of the coupling housings needs high surface finish and form accuracy as well as high purity of the connecting surfaces, in order to connect with small forces.
  • the plugging/pushing connection is not satisfactory as to safety, if the quick coupling socket (nipple) is a refuelling mechanism (tank lid) at the vehicle and the coupling plug is arranged at a fuel station, since the plugging connection can lead to heavy damages at the gas station and/or the vehicle when driving away in connected state.
  • the invention has the object to create a coupling for cryogenic mediums, in particular LNG, in order to improve operating safety over known couplings.
  • the handling and safety of the suggested coupling is substantially improved, since a locking element is actuated by the pivotal movement of the hand lever on connection to the nipple, preferably via collets, thus locking the hand lever in the connecting position. Any unintentional loosening of the coupling can thus be excluded in a safe manner.
  • the control of the flow path of the cryogenic medium to the nipple is achieved in type of a safe sequencing.
  • the latch of the coupling takes place in a separate step before. The same applies to uncoupling, so that it is ensured that the operator of the coupling does not come into contact with the cryogenic medium, which is reliably shut-off before unlocking of the hand lever by the control block and the control bar coupled thereto.
  • the simple structured control bar includes in particular a metal bellow, whose interior is connected to a control line.
  • the control line can be opened or closed via a control signal, as described in EP 0 889 273 A1.
  • FIG. 1 a perspective view of a coupling
  • FIG. 2 a side view on the coupling housing
  • FIG. 3 a longitudinal section of coupling shown in FIG. 2 in horizontal plane
  • FIG. 4 a longitudinal section of a control block in horizontal plane.
  • the coupling 1 shown in perspective view in FIG. 1 includes a coupling housing 11 for connecting two line ends.
  • the connection of the coupling housing 11 to a coupling nipple (here not represented) is made by several locking elements in the form of collets 30 .
  • a hand lever 15 is provided at the coupling housing 11 , which is pivotally mounted at an axis 16 and a relatively short spreading lever 17 is pivotally mounted adjacent to the axis 21 .
  • the required mechanical force is provided, which pulls the coupling housing 11 against the coupling-flat of the nipple provided with seals, wherein the spreading lever 17 achieves a power amplification in type of a toggle joint.
  • a relative small hand strength is sufficient in order to establish the coupling connection.
  • a lock sleeve 31 is shifted over the collets 30 , here to the left, to lock these in a positive manner, as described in several patents of the Applicants (e. g. EP 1 483 524 B1; internal Ref.: S 0041-P-EP).
  • a laterally projecting operation knob 22 is actuated. This operates a valve in the control block 20 (cf. FIG. 4 ), so that an input pressure at a pressure line P, e. g.
  • FIG. 1 further shows a main line 47 for feeding of the medium, likewise in FIG. 2 in side view, also indicating the section planes for. FIG. 3 and FIG. 4 with A and B.
  • a generally tubular coupling housing 11 forms an insulation chamber to prevent evaporation of deep-cold mediums, like LNG in the line ends.
  • the line ends lead to the parting plane of the coupling nipple (that is preferably connected to a fuel tank) and of the coupling housing 11 , which surrounds the main line 47 at least partially.
  • At each line end opposite valves are arranged to open or close the line ends adjacent to the respective front surfaces thereof, e.g. in the coupling housing 11 at least one seal 38 is formed of PTFE.
  • a control bar 36 is provided, which preferably also carries a seal from PTFE.
  • the control bar 36 is urged to a sealing surface via a compression spring 41 and also by a metal bellow 44 connected thereto.
  • the metal bellow 44 includes an interior chamber 45 , which is connected to a pressure generator (not represented) via a control line 46 .
  • Pressurized control fluid e. g. compressed air at 10 bar
  • the metal bellow 44 is extended in axial direction to open the medium or fluid inlet by the control bar 36 .
  • Releasing of the actuating pressure at the control line 46 (and thus the subsequent release of the fluid flow in the main line 47 ) is preferably made by a return line R at the control block 20 , as shown in FIG. 4 , i. e. only after the locking element 21 or the check pistons 21 a have “blocked” the hand lever 15 in the connecting position.
  • a return line R at the control block 20 i. e. only after the locking element 21 or the check pistons 21 a have “blocked” the hand lever 15 in the connecting position.
  • the interior 45 is balanced by means of the control line 46 .
  • the compression spring 41 pushes the control bar 36 and the metal bellow 44 into the closed position of the coupling. This is supported by the pressure in both line ends, since effective bellow and sealing surfaces cause additional closing forces.
  • the pressure at the pressure line P is also switched off, so that the check pistons 21 a retract towards the interior of the control block 20 and thus the hand lever 15 can be tilted up into its home position. Then, the lock sleeve 31 is simultaneously withdrawn and the coupling is separated, again.
  • a signal can be transmitted via the return line R on switching-off the pressure P at the control block 20 , whereby the safety standard is further increased.
  • This can be in form of a visual indication for the operator (e.g. “You can pay now/start”) or a release (“green light”) for the gas station personnel or an acoustic signal or an electronic unblocking (e.g. open a gate at the gas station).
