COUPLING Russian patent published in 2014 - IPC F16L55/10 F16L21/00 

FIELD: machine building.

SUBSTANCE: group of inventions refers to a coupling for the connection of channels for liquid media. The coupling comprises the first and the second half-couplings. The first half-coupling is made with the possibility of being connected to the second half-coupling by their relative movement along the connection axis. While used the axial tensile load for the coupling is taken up by a tensioning component. In order to disconnect the coupling without the tensioning component demounting it is necessary to apply tensile stress sufficient for the break of the tensioning component. So the tensioning component shall be broken into two parts along the line of a single rupture. As preferably one tensioning component is used, the accuracy of adjusting the force required to disconnect two half-couplings, is increased.

EFFECT: coupling is especially suitable for the connection of two pipeline parts providing for safety break function therewith.
