    The invention relates to a reinforcement and can be used to provide a tight shut-off of a pipeline with the help of shut-off and control valves with a butterfly valve, for example, such as a butterfly valve.
    The purpose of the invention is to improve the reliability of the sealing assembly by ensuring the mobility of the annular sealing element in the radial direction and axially due to the deformation of the conical part of the ring element.
    FIG. 1 shows a rotary disc valve, equipped with a sealing unit, a section; in fig. 2 — node I in FIG. 1 (the shape of the elements constituting the sealing assembly and the structural relationships between them).
    In the tubular body 1, a bore 2 is formed, forming an annular protrusion 3 with a lateral surface 4 perpendicular to the axis 5 of the body bore channel. The valve 6 is installed in the housing 1 on the axes 7 and 8, passing through the openings 9 and 10. One of the axes is connected with an actuator providing the rotation of the valve 6. The peripheral surface 11 of the valve 6, which interacts with the sealing element, is made conical. The sealing unit consists of an annular element 12, which provides dynamic tightness and is made Z-shaped with end sections 13 and 14. Section 13 is made with a straight cross section, and section 14 is displaced relative to it in the axial direction away from the valve . Sections 13 and 14 are connected by a conical section 15. The second component of the sealing assembly is a metal corrugated membrane 16, which is adhered by one condom to the side surface of the coic section 13. The other end of the membrane 16 contacts its section 17 with the side surface 4 of the protrusion 3 of the bore enclosures, ensuring static tightness. The pressing of the section 17 of the membrane 16 to this top is provided by a movable element 18, made in the form of a flange with radial surfaces 19 and 20 displaced one relative to another in the axial direction with the formation of a step. At the same time, the surface 19 through the resilient core 21 presses the portion 17 of the membrane 16, and the surface 20 fixes the end portion 14 of the element 12 against displacement in the axial direction, but allows it to move in the radial direction. In the wing 22 of the gland element 18, a series of threaded holes are made parallel to the axis of the passage channel, each of which has a screw 23 screwed in against the inner side of the wing 24. The wings 22 and 24 are connected by an elastic bridge 25, which acts as an elastic joint when exposed screws 23 on the wing 24 when the wing is axially held by the bar 26, the wing 22.
    At the end of the stroke of the disk valve 6 to close its conical periphery - on the surface 11 interacts with the end section 13 of the Z-shaped ring element 12. The presence of the corrugation in the central part of the membrane 16 allows its elastic deformation, which in turn gives the ring element 12 mobility in the radial direction. The connection of the end sections 13 and 14 conical section 15 provides mobility in the axial direction.
    Thus, the sealing element seals itself on the peripheral surface of the valve, which improves the contact conditions and improves the reliability of the sealing.
