MULTI-CHANNEL QUICK-DETACHABLE CONNECTION OF PIPELINES Russian patent published in 2012 - IPC F16L37/00 

FIELD: machine building.

SUBSTANCE: multi-channel quick-detachable connection of pipelines includes a core and a housing with axial and radial channels, locking device and elastic sealing element; besides, radial channels are located in one plane both in the housing and in the core and separated between each other with elastic sealing element that is arranged in annular and longitudinal grooves made in the core; at that, core has the slots interacting with projections on the housing, and bolt of locking device is rigidly fixed with one of its ends in the core, and it interacts with the other end to the split nut enclosed with case-key by means of its projections with slots of split nut, and interface surfaces of split nut and case-key have mutual slope; at that, case-key interacts with stroke restrictor installed in the housing of locking device, and stock of case-key is connected to an eye lug by means of connection elements.

EFFECT: invention improves reliability and manufacturability of quick-detachable connection of pipelines.
