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 12):
A device for the sealing of pipelines, the device comprising:\n a plugging machine for conveying fluids under pressure affixed to a connector made integral with and communicating with the pipeline, perpendicularly to the axis of the latter, with the device protruding downward from the plugging machine and inserted within the pipeline; a rigid tube supported by a body of the plugging machine and extended therebelow to pass through the connector and insert into the pipeline with axis almost orthogonal thereto; a stationary disc integral to a lower end of the rigid tube ( 2 ), arranged coaxial with respect to the pipeline and featuring an axial through opening to which an internal cavity of the tube is joined and which has a face shaped like a truncated cone; a movable disc arranged coaxial with and counter-facing the stationary disc with a relative face having a truncated cone profile symmetrical to that of the face of the stationary disc, with the movable disc featuring an axial shank adapted to be inserted slidably in the axial opening of the stationary disc, so that the mutual distance between them can be adjusted; a sealing ring of elastomeric material with a trapezoidal cross-section interposed between the stationary and movable discs, having its outer diameter dimension slightly less than an internal diameter of the pipeline in non-operating condition (R) when no axial compression is exerted on the discs, with the stationary and movable discs mutually moved away, the ring being designed to expand radially, in operating condition (W), in a manner as to adhere sealingly to the inner surface of the pipeline as a consequence of an axial compression exerted by mutual approaching of each disc; a control rod slidably inserted in the tube, extended upwards to come out from the body of the plugging machine and downwards to abut against the axial shank of the movable disc; sliding drive means provided between the lower portion ( 6 B) of the control rod and the shank of the movable disc, operated by axial translation of the rod so as to make the shank and the movable disc, rigidly coupled therewith, carry out corresponding axial movements away from or close to the stationary disc to cause respectively the non-operating (R) and operating (W) conditions of the sealing ring; and operating means, associated to the upper portion of the control rod, provided to determine axial movements of the control rod.
