PULL-OUT CONNECTOR FOR HYDROCARBON SYSTEM Russian patent published in 2015 - IPC F16L37/62 

FIELD: machine building.

SUBSTANCE: invention is related to a connector for a hydrocarbon system. The connector for a hydrocarbon system comprises the first pipeline section, the first connecting part attached in a sliding manner to the first pipeline section to couple with the mating connecting part attached to the second pipeline section, and a pull-out element connected to the first connecting part for its movement in the axial direction. The first connecting part comprises essentially a T-shape core including a cylindrical part, a cross part and a central channel connected to the first pipeline section to transport hydrocarbons, a coupling set in a sliding manner around the core and having an upper and a lower cross walls contacting with the core, a longitudinal wall passing between the cross walls and at its lower end forming a conical cavity to place a connecting head of the second connecting part in the form of the truncated cone. The pull-out element can be actuated by the fluid medium pressure and one its end is connected to the coupling and the other - to the core.

EFFECT: invention improves reliability of the connection.
