    This invention relates to a valve industry. It is known a locking device, in a tubular body of which on a swivel axis, perpendicular to the axis of the channel, a shut-off valve is installed, equipped with a sealing element in contact with the seat ij. In the known device, tightness in the closed position is ensured by the presence of a relatively large radial protrusion on the sealing element that interacts with the seat bearing surface, which leads to increased friction in a position close to the closing position and, consequently, to considerable wear of the seal and increased force required to turn the flap. The purpose of the invention is to increase the durability and decrease the power of the drive. To achieve this goal, a locking device containing a tubular body with a bore and a locking member located in it, made in the form of a shutter mounted on a rotary axis, perpendicular to the axis of the channel, can interact with the saddle and is provided with a sealing element in contact with a saddle along the line of tightness, the latter is formed by a set of points, each of which is the intersection point of a tangent to a circle with a center that coincides with the axis of a lie (the valve’s value, and a radius equal to Standing from the axis of rotation to airtightness, with a plane tangential to the surface of the saddle. The tangent is inclined to the plane at an angle of 20-30. The profile of the line of tightness in cross section with the plane passing through the axis of the passage channel perpendicular to the rotary axis of the flap is formed by smooth coupling straight and convex-concave sections. The extreme points of the profile are located on the same line with the point of intersection of the axis of rotation of the gate and the axis of the passageway. The surface of the gate, on which the corner element is fixed, you filled with convex. The convex surface of the flap is made as part of a cylindrical surface with a generator parallel to the rotary axis of the flap. This embodiment provides up to | Strengthening tightness around the entire perimeter of the valve by simply squeezing or gradually pressing the seal. FIG. I shows the locking device in the closed position, a longitudinal section; in fig. 2 - the same, in the open position; in fig. 3 is a view A of FIG. 2; in fig. 4 - locking organ; in fig. 5 - stop valve and. seat in partial open position; in fig. 6 - locking organ.

    A cylindrical cavity 3 is made in the housing I of the intended locking device, provided with connecting flanges 2, and is formed by a cushion 4 with two side surfaces 5 and 6 having different inclination. Surfaces 5 and 6 intersect along an edge 7 forming a loop of irregular shape around the X-X axis of the passageway. The locking organ 8 is seated on a key on the axis of rotation 9 with the axis U-U, perpendicular to the axis X-X and intersecting it at the point O, Axis 9 is connected with the drive. The locking body 8 has one flat surface 10, one convex surface II and two convex, locking the volume of the locking body side surfaces 12, through which passes the axis 9 of the locking body.
    Along the entire periphery of the convex surface 1I, a sealing element 13, made of elastomer, passes and represents a protrusion on the shell 14, which covers the entire closure body 8. The cross-section of the sealing element 13 has the shape of a triangle with the top 15 lying on the sealing line of the sealing element along which contact of the valve body with the saddle. .i
    In the closed position, the devices Sedpo 4 and the locking member 8 have a common plane of symmetry &, perpendicular to the Y-V axis and passing through the X-X axis of the flow channel.
    Around the perimeter of the canap, t, e, at any point G of the tightness line, an area D, tangent to the tightness surface or saddle, forms an acute angle C ° of constant magnitude with a tangent to the circle of radius R and axis U – U passing through point G ( Fig.8),

    The surface 11 of the closure member 8 opposite the flat surface 10 is a cylindrical convex surface forming 15 parallel to the axis of rotation YV, but may also have a concave shape (FIGS. 6 and 71 with a generatrix perpendicular to the axis YV). In both cases the locking member has an aero or hydrodynamic profile in the fully open position and, therefore, has minimal resistance to the flow.
    Figs 8 and 9 depict a sealing operation 5. At each point, the sealing element comes into contact with the saddle 5 at its apex. Continuing rotation of the locking member 8 causes the sealing element to compress with the Q deformation of the elastomer, but in the complete absence of slip or friction.

    the sealing element, t, e, is the size necessary and sufficient around the perimeter of the closure member: and the surface of the sedp to ensure tightness in the closed position of the closure member at a certain working pressure. In practice, an angle of fixed constant of about 20-30, tolerance can be assumed. change its value by several degrees in one direction or another at some points of the tightness line in order to mitigate changes in the bending of the surface 5 of the seda, Depending on the choice of the angle
