Abstract:
This invention relates to a plugging machine and a rigid tube provided with a stationary disc integral with the bottom of the tube and oriented almost orthogonal to the tube, with a movable disc paired with the stationary disc. A sealing ring of a resilient material is located between the discs and compressed when the movable disc is pressed against the stationary disc to adhere to an inner surface of the pipeline. The sealing ring is coaxial with respect to the pipeline. The movement of the movable disc is determined by raising or lowering a control rod within the tube by means of sloping sliders made in the lower portion of the rod which engage in respective grooves, likewise sloping, made in an axial shank associated with the movable disc and sliding inside an axial opening of the stationary disc. A component of a force is generated which is parallel to the axis of the discs. The axis is raised or lowered by rotation of a threaded ring engaging in a threading mate at the top of the rod.

Claim (Index 1):
A device for the sealing of pipelines, the device being associated with a plugging machine provided for the execution of maintenance and/or repair in said pipelines, through which fluids are conveyed under pressure, and intended to be fixed to a connector ( 110 ) made integral with and communicating with one of said pipelines ( 200 ), perpendicularly to the axis of the latter, with said device ( 1 ) protruding downward from said plugging machine ( 100 ) and inserted within said pipeline ( 200 ), said device comprising:\n a rigid tube ( 2 ), supported by the body ( 101 ) of said plugging machine ( 100 ) and extended therebelow to pass through said connector ( 110 ) and insert into said pipeline ( 200 ) with axis almost orthogonal thereto; a stationary disc ( 3 ), integral to a lower end ( 2 B) of said rigid tube ( 2 ), arranged coaxial with respect to said pipeline ( 200 ) and featuring an axial through hole ( 30 ) to which the internal cavity ( 20 ) of the same sleeve ( 2 ) is joined and which has a relative face ( 31 ) shaped like a truncated cone; a movable disc ( 4 ), arranged coaxial with and counter-facing said stationary disc ( 3 ), with a respective face ( 41 ) having a truncated cone profile symmetrical to that of the face ( 31 ) of the stationary disc ( 3 ), with said movable disc ( 4 ) featuring an axial shank ( 40 ) adapted to be inserted slidably in said axial hole ( 30 ) of the stationary disc ( 3 ), so that the mutual distance between them can be adjusted; a sealing ring ( 50 ) of elastomeric material, with a trapezoidal cross-section, interposed between said stationary ( 3 ) and movable ( 4 ) discs, having its outer diameter dimension slightly less than the internal diameter of said pipeline ( 200 ), in non operating condition (R) when no axial compression is exerted on said discs, with the stationary ( 3 ) and movable ( 4 ) discs mutually moved away, said ring ( 50 ) being designed to expand radially, in operating condition (W), in a manner as to adhere sealingly to the inner surface of the same pipeline ( 200 ), as a consequence of an axial compression exerted by mutual approaching of said discs ( 3 , 4 ); a control rod ( 6 ), slidably inserted in said tube ( 2 ), extended upwards to come out from said body ( 101 ) of the plugging machine ( 100 ) and downwards to abut against said axial shank ( 40 ) of the movable disc ( 4 ); sliding drive means ( 7 ), provided between the lower portion ( 6 B) of said control rod ( 6 ) and said shank ( 40 ) of the movable disc ( 4 ), operated by axial translation of said rod ( 6 ) so as to make said shank ( 40 ) and the movable disc ( 4 ), rigidly coupled therewith, carry out corresponding axial movements away from or close to said stationary disc ( 3 ), so as to cause respectively said non operating (R) and operating (W) conditions of said sealing ring ( 50 ); operating means ( 8 ), associated to the upper portion ( 6 A) of said control rod ( 6 ), provided to determine said axial movements of the latter.
