A dealing ring (50) of a resilient mater- , . 6A 91 ---- z \ t ial is located between the discs (3, 4) and compressed when the movable disc , 80 (4) is against the disc (3) to adhere to an inner pressed stationary surface of .,.. A p o the pipeline (200). The sealing ring (50) is coaxial with respect to the pipeline ------' (200). The movement of the movable disc (4) is determined by raising or 90 2A j 102 lowering a control rod (6) within the tube (2) by means of sloping sliders (70) .- 1 1 01 made in the lower portion of the rod (6) which engage in respective grooves 92 I likewise in (44), sloping, made an axial shank (40) associated with the mov- t Aro i I aaa able disc (4) and sliding inside an axial opening of the stationary disc (3). A Pr component of a force is generated which is parallel to the axis of the discs A (3,4). The axis is raised or lowered by rotation of a threaded ring (82) enga- in a threading mate at the top (6A) of the rod (6). ging s , t k 120 11 110' - .4t .• ll• N IN , 200 28 11 1-1 FIG.
