    • 专利摘要:
    Two coaxial metal pipes, whose confronting extremities are each provided with a plurality of peripheral ribs of staggered height separated by two or more peripheral grooves, are interconnected by a coupling sleeve of fiber-reinforced thermosetting resin subdivided into several coaxially interleaved and independently deformable cylindrical shells each terminating in a pair of internal beads engaged in a respective peripheral pipe groove. The shells, increasing in axial tensile strength from the innermost to the outermost one, are preferably separated from one another by interposed antibonding layers of thermoplastic resin. A resinous filler can be inserted between the pipe extremities for electrically insulating them from each other. The shells of the coupling sleeve can be formed by coiling resin-coated filaments around the pipe axis, advantageously with application of an antifriction layer on each inner shell before the thermosetting material thereof has been fully hardened.

    (54) PIPING CONNECTIONS
    one
    This invention relates to mechanical engineering, in particular to pipe joints.
    It is known to connect pipelines, along the channel of which at their outer ends there are annular grooves of shaped pipe and sealing joint 1,
    The specified connection of pipelines does not provide the necessary degree of strength of the connection.
    It is also known to connect pipelines, along the channel of which, at their outer ends, annular grooves of a shaped profile and shoulders are made, on which a connecting element is located above the insulating and sealing ends of the pipes at a certain distance, the entrance to the annular grooves of the shaped profile and connected overlap with shoulders 2.
    However, this device does not provide the strength of the connection.
    The purpose of the invention is to increase the strength of the joint.
    This goal is achieved by the fact that the connecting node, starting from the channel side of the pipeline, is designed as successively arranged
    insulating shells with a profile flange, as well as with sliding jacks that alternate with insulating shells, on the outer of which a protective tube is installed, with the sliding shirts adjacent to the insulating shells.
    Burt covered with inhibitors of single, aluminum or alloys or mixtures of organic substances, such as titanium dioxide, and shells are covered with an insulating diffusion layer.
    FIG. 1 shows the described compound, part of a longitudinal section; FIG. 2 - half of the segment of the insulating pipe joints; FIG. 3 shows a connection with a part of the sliding layer; Figs 4 and 5 are sliding layers; in fig. 6 shows an embodiment of pipes, a part of a longitudinal section.
    The piping connection consists of shells 1, 2 pipe ends with shoulders 3, sliding shirts 4, annular grooves 5, springy longitudinally-slotted pipe 6, moving layer 7, insulating shells 8, protective pipe 9, profile flange 10, sealing ring II , films 12 and 13, protective
    insert 14, the groove 15 and the insulating layer 16.
    The ends 2 of two pipes cover the shell 1, for example, from reinforced plastic. Overlapping shell 1 consists of two shells separated from each other in the axial direction. The ends 2 of the overlapped pipes each have two shoulders 3, Cg1 each of the two ends of the shell can be separated by sliding jackets 4. The ends 2 of the protective pipe 9 can be thickened in order to make the grooves 5. However, the shoulders 3 can be formed by annular discs (on not shown), rigidly connected to the pipe by welding. The protective pipe 9 may consist of any material, for example, plastic or metal, in particular steel. The overlaying shell 1 is produced by winding. by crimping for pouring in the zone of pipe ends 2, if they are made by winding, the bundles of reinforcing fibers first pass through the resin bath and when they are wound on the core according to a given pattern, they first form the wall of the shell of reinforced plastic. For manufacturing - the insulating joint of the pipes, the core is replaced by a profile flange 10 and during the winding process the collar 3 completely walks into the end of the shells 1 of reinforced plastic. It is also possible to wind the reinforcing fibers pre-impregnated with resins, without resin baths. .
    Each shoulder 3 has annular grooves. Which ensure the transmission of force in connection with the triaxial state of the voltage from the end 2 of the pipe.
    The shell 1 of plastic on the outer side is partially covered with protective tubes 9, which cover, in particular, the zone of all annular 5 3 3
    grooves 5. In the area between the protective tubes and their outer surface, a protective insert 14 of soft elastic insulating mass for castings is coaxially formed. The protective tube 9 may be made of metal.
    FIG. 6 shows an embodiment of the joint in which the protective tube 9 is made of laminated plastic with embedded fibers. The fibers may be glass, carbon or steel. The entire connection can also be completely wrapped with a layer of insulating tape and covered with paint.
