    (57) The invention relates to reinforcement building, namely to butterfly valves for shutting off pipelines transporting various media and
    allows you to increase the tightness of the connection of the valve body to the flanges of the pipelines by imparting a directional deformation to the elastomer cuff 9 installed in the central passage channel 8 of the body 1. The cuff 9 is made with radial jaws placed in the counter grooves of the body. The profile of the grooves provides for placement of the cuff sponges in the non-operating position of the flap with the formation of a free annular space. The volume of space is equal to the volume of the convex portion of the sponge of the cuff 9, which, when the flange is pressed against the valve body 1, moves the sponge elastomer into its own. body space, excluding its movement to the central part of the cuff, which prevents increased wear and loss of tightness. 4 з.п, ф-л, 4 Il.

    The invention relates to the field of fittings, in particular, to: gate valves for shutting off pipelines transporting various media.
    The aim of the invention is to increase the tightness of the connection between the valve body and the pipe flanges.
    FIG. 1 shows a flap, partial axial section; in fig. 2 is a sectional view in FIG. 1; in fig. 3 - part of the valve body with an elastomer cuff and a flange of the connected pipeline; in fig. 4 - mounting the valve between the two flanges and dismantling one of the flanges while maintaining the working pressure, section.
    The valve body 1 is made with tides 2 under the holes 3 of the fastening elements to enable it to be installed between the flanges 4 and 5 of the attached pipelines. The housing 1 is bounded by two parallel radial lateral surfaces 6 and 7, it has a central passage channel 8, the surface of which is covered with an elastomeric cuff 9 with a V-shaped cross section, and 5, an ion hole 10, through which the cause a shaft 11 with a disc locking member 12 installed therein. The cuff 9 is provided with a central portion 13 and radial jaws 14 and 15, spacer; ENP in the counter grooves 16 and 17 of the housing. The grooves 16 and 17 are made in the form of extended sections 18 of a curvilinear profile located in the continuation of the passage channel 8, passing into a conical radial section 19. The latter passes into an annular groove 20 bounded by a cylindrical surface 21, a bottom 22 and a surface 23. Each jaw 14 , 15 cuffs 9 has an internal surface profile that responds to the shape of the body groove, while the outer diameter of the sponge is smaller than the diameter of the surface 23 of the groove 20, resulting in a non-working position of the valve between the surface 23 and the outer edge ubki remains free an annular space 25.
    Each of the jaws 14 and 15 has an outer surface profile consisting of a flat portion 26 located in the plane of the radial surface 6, and a convex portion 27, the volume

    which for the plane of the surface 6 is equal to the volume of the annular space 25.
    When flanges 4 and 5 are pressed against the valve body 1, their radial surfaces compress the convex sections 27 of the cuff to the level of the radial surfaces 6 and 7 of the body and cause the sponge elastomer to move into the free volume of the annular space 25. Thus, the deformation of the cuff is directional. The elastomer does not move to the central portion 13 of the cuff, which may adversely affect the degree of tightness and the amount of drive force. The curvilinear profile of the groove in section 18 allows any ripping to be opposed by the forces arising in the cuff 9 (tension, compression).
    To dismantle the downstream pipeline while maintaining the working pressure therein, fasteners are unscrewed from the flange. In this case, the flap is in the closed position, and its body remains pressed against the upstream flange.
