    专利说明:

    The invention relates to pipe socket connections and can be used when laying large diameter pipes in trenches when bends are unavoidable and the medium passes under high pressure. A well sealed pipe joint is known, one of which is smooth and the other with a socket with opposite support The surfaces between which the movable ring element seals the incompressible mass of the PZDannoy connection inherent lack of tightness with angular deviations. The purpose of the invention is to increase the tightness of the joint in case of angular deviations. To achieve this goal, in a hermetic socket connection of pipes, one of which is smooth and the other with a socket with oppositely arranged supporting surfaces, between which an axially movable ring element is installed. compacted incompressible mass in the direction of the support surface of the razrzgba, the annular element is made in the form of a sleeve with at least one outer flange and is installed with a radial clearance no inner surface of the socket and the outer surface of the pipe SFA Coy and vto incompressible mass. Vienna in the form of metal balls. FIG. 1 shows a general view of the compound in FIG. 2 is a partial sectional view of the compound in an enlarged scale in FIG. 3 is a partial cut of the joint embodiment. The connection contains a smooth pipe 1, which enters the socket 2 of the other pipe, ending with a flange 3 with an opening 4. An additional internal flange 5 is made on the inner surface of the socket with a confining hole 6, which is slanted inside the socket, whose diameter is smaller than the diameter of the opening 4. Behind the flange 5 An annular step-shaped recess is installed, into which a sealing gasket 7 is installed, ensuring the tightness of the connection when pressed. At the smooth end of the pipe 1, at some distance from its end face, the welded gas pipe 8 is made circular or perpendicular, bevelled in the direction opposite to the end of the pipe. The diameter of the seam 8 is smaller than the diameter of the opening of the flange 5, and when the end of the pipe is fully inserted into the socket, this seam is located almost opposite the internal flange 5. On the pipe from the end face up to the stop into the seam 8 there is a ring 9 with a slot 10. Between the opposite support surfaces flanges 3 and 5 are mounted with a radial clearance relative to the inner surface of the socket and the outer surface of the pipe, an axially movable annular element in the form of a cut sleeve 11 with at least one outer flange 12, sealed my mass in the form of metal balls 13 in the direction of the support surface of the flange 3 of the socket. The balls 13 are introduced into the cavity 14 through an opening 15 made in the socket and closed with a stopper 16. The assembly of the joint is carried out as follows. Having installed the sealing element 7 in a stepped undercut, behind the flange 5 they begin to compress in the radial direction the sleeve 11 until the diameter of its flange 12 is sufficient to pass through the opening 6. After this, the flange 12 is released and the slot is closed using, for example , welding so that the sleeve 11 becomes solid in detail over its entire peripheral surface with a diameter sufficient to form gaps / and o Then a ring 9 with a slit 10 is inserted in the same way for the sleeve 11 and subjected to its radial stretching (for examplea wedge is inserted into slot 10) -. The end of the pipe. 1 is inserted into the bell 2, the passage through the sleeve 11 and the ring 9. When the weld seam 8 has passed behind the ring 9, the spacer wedge of the slot 10 is removed so that the ring covers the end of the pipe before the weld. During the insertion of the pipe 1 into the socket, the gasket 7 is radially compressed, thereby automatically ensuring the tightness of the connection. After that, the pipes are bent relative to each other or they are bent to the limit, which is required by the working conditions. When both pipes are in their final position, the cavity 14 is filled with an incompressible mass in the form

    balls 13 through holes 15 in the length of a ball, and then compacted by vibration. During the filling of the mass of the cavity 14, it pushes the flange 12 to the ring 9 in such a way that at the end of the filling the flange 12 is located coaxially with the pipe 1. This angular movement of the flange 12 becomes possible due to the presence of gaps and I, which vary along the entire perimeter of the socket , but cannot be doubled and, therefore, remain smaller than the diameters of the balls. This ensures that the balls cannot jump out of the cavity 14 of the AI outwards or inwards. | After this, hole 15 closes: with a cork 16 "Under the action of the worker32799 .l
    The pressure of the end of the pipe 1 will be. strive to get out of the socket 2, the separation forces will be transmitted to the booster; a weld 8, flange 3 and to the inner surface 5 of the socket through the ring 9, the flange 12 of the sleeve 11 and the balls 13.
    The design variant (Lig. 3) differs only in the shape of bushings 11 and 10 of ring 9.
    The ring 9 has a triangular cross-section with cut corners, and on the sleeve 11 the flanges are made with two hundred5 pins.
    The proposed connection ensures its tightness at angular deviations of pipes.
