摘要： Connection for fluids comprising a movable hollow joint (1) equipped with a lateral tubular duct (15) and two conical through-holes, opposite and coaxial (2) and (2') whose axis is perpendicular to that of the lateral duct; a clamping screw inserted in the through-holes (2) and (2') of the joint (1). The shank (3) of said screw is provided with a central duct (12) coaxial with the axis of said holes (2), a transversal hole (14) which connects said duct (12) with the internal chamber (13) of the joint and two round grooves (10) and (11) at said through-holes (2) and (2'); and flexible round gaskets (9) and (940 ) inserted in said grooves (10) and (11).

摘要： The pipe (2) is inserted in the through-hole of the flange (1) and the pipe-flange seal is assured by a fixing ring nut (6) screwed into the upper portion (5) of the hole.The hole, in the part opposite the threaded area (5), has an area (4) with a diameter equal to that of the pipe (2) and a truncated-cone coupling area (4) between the two areas (5) and (7). A ring (8) of elastomeric material is inserted inside the truncated-cone portion (7) and an annular projection (9) on the pipe (2) acts thereon, pushed by the screwing action of the ring nut (6).
