QUICK-DETACHABLE CONNECTION OF PIPELINES Russian patent published in 2019 - IPC F16L37/00 

FIELD: machine building.

SUBSTANCE: invention relates to split joints of pipelines and can be used in various hydraulic systems of self-propelled machines. Quick-fit connection of pipelines consists of male and female half-couplings and device for their connection and disconnection. Each of half-couplings is made of nozzle with means for connection of pipelines for supply of working fluid, symmetrical axes of half-couplings arranged in channel spring-loaded valve and sealing rings arranged inside housing. In order to eliminate leakage of liquid drops outside during coupling-disconnection of half-couplings in each half-clutch between the union and housing there is a sealing ring, and inside male coupling half sleeve is installed with holes for working fluid passage, with located in it spring, one end of which rests against inner surface of valve. Latter is made with shank, end part of which enters inner hole of sleeve, and other end of spring enters inner hole of sleeve. In housing of female half-coupling there is holder with holes for liquid passage, in which rod with groove for sealing ring is fixed with possibility of detachment, besides, spring-loaded sleeve and spring-loaded barrel are installed inside the housing of half-coupling, which is movably installed inside the holder. On the outer side of the body of the female half-coupling there is a device for connection and disconnection of the half-couplings, resting on the sleeve, as well as a retainer, a return spring and a locking ring.

EFFECT: proposed is a quick-detachable connection of pipelines.
