DEVICE TO CONNECT PIPELINES OF TWO OBJECTS Russian patent published in 2014 - IPC F16L39/00 

FIELD: machine building.

SUBSTANCE: device to connect pipelines of two objects comprises the following units set on the stationary housing of one object and on the replaceable housing of another object: a locking device with a hand drive, telescope mating junction pieces with spring-loaded valves and supply channels, each junction piece at the replaceable housing is fitted by a piston with a spring-loaded wringing valve and the piston is provided with a port connecting the input cavity of the supply channel and the inner cavity of the piston. Sealing elements are set on the piston beyond the port zone, and a drive mechanism for piston displacement with a hand drive is installed in each junction piece of the replaceable housing coaxially to the junction piece axis so that to provide for the piston displacement from the level of the replaceable housing surface being matched to the connection of the replaceable housing's junction piece with the input of the supply channel by the piston port.

EFFECT: provision for carrying out of such manual operations as gripping, tightening, matching and fastening of heavy-weight objects with great moments of inertia and provision of reliable sealing.
