    The invention relates to mechanical engineering and can be used to seal flanged connections of tanks, apparatus, large diameter pipelines, and the like. The purpose of the invention is to increase the tightness of the joint. The joint contains two connected parts 1, 2. Flanges with annular conically widening 5 cavities are fixed to the parts. When the flanges are tightened with the clamping means 4, these cavities form a sealing chamber in which the sealing part 7 is placed in the form of an elastic elastomeric ring. Item 7 is made with an annular groove on the inner surface. An additional ring with an annular thrust collar 9 on the inner surface is installed in the groove. The flanges, compacted by clamping means 4, form a triangular in cross section chamber, completely filled with a sealing part. 7 hp f-ly, 10 ill.

    The invention relates to mechanical engineering and can be used to seal flanged connections of tanks, apparatus, large diameter pipelines, and the like.
    The aim of the invention is to improve the tightness of the connection.
    FIG. 1 shows a welded flange joint before assembly (tightening), a longitudinal section; Fig. 2 - the same, after assembly (puff); in fig. 3 flange connection with loosely mounted flanges prior to assembly of the joint, longitudinal section; Figure 4 is the same after connection; in fig. 5 - flange, an example of implementation; figure 6 is the same cross section; 7 shows a flange segment; on Fig - the same, side view; in fig. 9 - the same, top view 2; Fig "10 - ring washer, cross section.
    The flange connection contains two parts 1 and 2 with the flanges 3 fixed on them. The flanges are stitched between co-2 parts by clamping means 4 On the surfaces of the flanges 3 interconnected towards the connecting joint 5, the surfaces of the flanges 3 are made annularly widened forming the sealing chamber 6, in which the sealing part 7 is installed, the sealing part is made in the form of an elastic ring made of elastomer material with an annular groove ™ on the inner surface, in which additional Ring 8. The latter has an internal annular thrust collar 9 and is installed in the sealing part 6 freely, the flanges 3 can either be welded to the respective parts 1 and 2, or can be mounted on them freely. When welding the flanges, the welds 10 are spaced apart, since they only perceive the joining forces. With free installation of flanges on parts 1 and 2, the flanges are made with chambers 11 located at the ends of the flanges opposite to the joint. At least one clamping element 12 is installed in these chambers. The clamping element has a shape convex in section in a free state and protrudes outwardly into chamber 11. Clamping means k interact with clamping elements 12, changing their shape, while the section 12 of elements 12 takes place. linear shape, uve

    its height and reliably Flanges are worn to parts 1 and 2.
    The flanges 3 (at least one) can be made of at least two segments 13 with axially arranged ribs 14, fastened elements 15 assembled in assembled form 15. The inner surface of each segment 13 can be made with a bead in which the segment is located pressure ring 16. The latter is made sawtooth form of solid material.
    In order to avoid damage to the sealing part when tightening individual flange segments 13, an annular conical washer is installed in the expansion chamber 6. The flanges can be made in the form of round-curved sections of an infinitely shaped material, as well as an elastomeric part and an additional ring lanes.
    As clamping means k, segment bolts can be used.
