QUICK-DETACHABLE CONNECTION FOR HYDRAULIC AND PNEUMATIC LINES Russian patent published in 2020 - IPC F16L37/28 

FIELD: machine building.

SUBSTANCE: invention relates to hydraulic (pneumatic) quick-detachable joint providing for connection and detachment of pneumatic or hydraulic lines, and can be used in machine building, deep-sea and rescue operations. Invention improves reliability of device by excluding aggression of corrosive liquids pressing elements and increases functionality of device and possibility of passing through one and the same structure of various liquids and gases, including aggressive ones, and thus improves reliability of connection lines due to optimum docking of valves.

EFFECT: providing connection of valve shutoff parts with sealing elements outside the device, on the side of action of working liquid (gas), equipping cylindrical parts of valves extending beyond the device in docked state, by means of holes in contact with working fluid, and design of valves with through holes, providing for coupling and closure of half-couplings of free passage of working fluid, that is a hydraulic (pneumatic) line, as well as arrangement of pressure elements inside the cavity of the device, thereby eliminating contact of springs with working fluid.
