    A valve body for a spherical-shutter valve for gases or fluids is disclosed, said body consisting of two hemispherical hoods enclosing the shutter and to be welded along their great circle, two couples of half-rings being welded in symmetrical positions relative to the sphere equator to provide sealing action: an annular channel is furthermore provided in the meridian direction immediately beneath the welding seam line to prevent welding material from entering the valve interior and to house a photographic film to take nondestructive control pictures.

    The invention relates to pipe fittings, in particular to spherical valves, having a welded body and designed to cut off the flow of liquids or gases on pipelines of large diameter.
    The purpose of the invention is to simplify the installation and dismantling of the crane and simplify its design due to the possibility of automating the processes of welding the two halves of the crane body and cutting the crane body on the lathe into two halves with subsequent re-use of the ordered welded halves of the crane body.
    FIG. 1 shows a spherical tap, section; in fig. 2 - the same, isometric, disassembled; in fig. Node 1 in FIG. 2
    The spherical valve contains a housing consisting of two hemispherical parts 1 and 2, welded to each other along the peripheral edges 3 and 4 with a single seam 5 and made respectively
    with inlet 6 and outlet 7 CYLINDER connections. In the case installed; spherical stopper 8 with a rotary axis of rotation 9, perpendicular to the axis 10 of cylindrical nozzles, with a cylindrical through channel 11 for the passage of working medium and two pins 12 and 13. In the case there are floating o-rings 1A and 15 with sealing gaskets. in the plane perpendicular to the axis 10 of the cylindrical nozzles, and represents the shortest connecting line. On the pins 12 and 13 of the spherical plug 8, two disks 16 and 17, which serve as rolling bearings, are slidably mounted. Inside each hemispherical part 1 and 2 of the body at an equal distance from the axis 10 of the cylindrical nozzles, two pairs of half-rings 18, 19 and
    242
    20, 21, the concave surfaces of which face each other.
    The trunnions 12 and 13 of the spherical plug 8 do not extend beyond the spherical
    the surface of parts 1 and 2 of the body due to the fact that part of the surface of the spherical tube 8 is cut off.
    The rotation of the spherical plug 8 is carried out under the influence of an external drive inserted into the groove 22 of the trunnion 12, and the drive shaft is driven through a bore 23 formed in the walls of the hemispherical parts I and 2 of the housing.
    On the edge 3 of the hemispherical part 1 of the housing inside it, under the weld seam 5, there is welded an annular strip 24 U -shaped, protruding outwardly from this edge and having a groove 25 facing the inner surface of the part 1 of the housing.
    When welding hemispherical parts 1 and 2 of the body of the semiring 18 and 19, part 1 coincides with the semiring 20
    and 21 parts 2, forming two annular lines covering disks 16 and 17.
    Circular skins along with discs 16 and 17 are centering guides and receptive
    force elements to ensure the rotation of the spherical tube.
    An LJ-shaped annular strip 24, located directly below the weld pool, together with the walls of the hemispherical parts 1 and 2, forms a cavity that prevents the welding material from entering the inside of the faucet and can be used to insert a film into it.
    used in radiographic inspection of the weld.
    When the weld is cooled, annular strips formed by pairs of half-rings 18 and 19 and 20 and 21 counteract the tightening of the weld. Is.
