MULTICHANNEL QUICK RELEASE COUPLING Russian patent published in 2015 - IPC F16L37/00 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, namely to multichannel quick release couplings of pipelines, and can be used where multichannel transportation of liquids, gases and fast, reliable separation of pipelines at some point, mainly in space rocket applications, is required. The multichannel quick release coupling contains the housing with the pipeline channels inside connected by means of hinged connections one ends of which are implemented in the form of spherical tips. The hinged connections are spring-loaded, and spherical tips of the hinged connection interacts with internal surfaces of pipeline channels which are conic and self-sealed by means of the sealing rings and protective washers placed in grooves of pipeline channels, and other ends of hinged connections from the side of companion pipeline channels with larger diameters, are implemented in the form of a part of sphere with the grooves for O-rings and protective washers, while the quick release coupling is clamped together with the lock device, and for prevention of mutual shift of plates of the housing the fixing elements are located inside.

EFFECT: invention provides tight and reliable connection and separation of pipelines.
