    The invention relates to the field of reinforcement. The known design of a disc valve, in the passage channel of the casing of which a seat is mounted with a clamp attached to it to a shut-off organ, which is made in the form of a shutter with an annular sealing. edge mounted on an offset axis of symmetry of the drive axis valve with the ability to rotate and interact. Without any contact with the seat gasket 11. A disadvantage of the known construction is a significant ipeioie between the seat and the disk seal that i-reins provide significant positive forces as in opening, and at klorapsh kliana. The aim of the invention is to reduce drive power. To achieve the indicated target in a disc valve containing a housing with an inlet duct, in which a seat is installed with a procluster fixed on it and a locking member made in the form of a damper with an annular sealing rabbit mounted on a drive axle positioned relative to the axis of symmetry of the drive axle with the possibility of rotation interaction on lsgg and contact with prokladasoy sedia, gentle damper is formed by two union surfaces of different profiles, located on either side of the plane of symmetry of the damper, passage The axis is transient through the drive axis, and the transitional surfaces are located at the plane of symmetry, while the similarity points and normals to the tact of the main surfaces of the edge 5 with the fold are located on the axis of symmetry of the spacer on both sides ot leading the axis at a distance not exceeding 0.15 of the valve diameter, and the points of intersection of the normals to the contact of the contact with the gasket intersect 1x the surfaces of the edge with the axis of symmetry are located between the points of convergence of the normals of the main surfaces. In this case, the main surfaces of the flap edges can be made spherical with centers at the points of convergence of normals, coic, toroidal, or multitoroidal. FIG. Figure 1 shows schematically a disc valve, a section along the axis of rotation of the valve, offset and decentralized relative to the axis of its rotation; in fig. 2 valve, incision perpendicular to the axis of rotation; in fig. 3 is a schematic depiction in perspective of a valve with zero eccentricity; in fig. 4 n 5 shows the force distribution schemes experienced by the valve when the valve opens when the forces are directed along the axis of the valve (Fig. 4) and when they are not directed along the axis, but have a minimum shoulder (Fig. 5); in fig. 6 is a schematic representation in Perspekgava of a flap with a supporting surface; in fig. 7 is a diagram of the arrangement of the normals to the support surface of the valve; in fig. 8-10 are the options for obtaining the supporting surface of the valve, respectively, using douh spheres (Fig. 8), two cones (Fig. 9), two to be bent (x rays (Fig. 10); in Fig. Pshematish image of the valve with a bitoroidal supporting surface. In the housing 1 of the disc valve, a passage 2 is made in which a shut-off element is placed, made in the form of a flap 3, which interacts with its annular sealing edge 4 with a gasket 5 fixed to the seat 6. The flap 3 is rotatably mounted when noMoim OJOcHbix semi-axes 7 are offset and decentr aannyh relative flap 3. Hia FIG. 3 shows a variant with flap performing nzlevym center offset from the axis of rotation 8 to the axis 9 of symmetry.
    The shape of the sealing lip 4 provides, for the forces experienced by the flap upon opening, with respect to the axis of rotation of the semi-axes, the shoulder value close to zero. The directions of the forces F are inclined relative to the normal of the section of the edge of the flap in the plane A, perpendicular to the axis of rotation 8, by the angle equal to the friction angle of the pair of saddle - edge 4 of the flap 3.
    FIG. Figures 4 and 5 show the distribution of forces in the plane A, experienced by the valve 3 when it is opened, in the case when they pass through the axis 8 rotates, and in the case when they do not pass through it, but have a shoulder of minimum size, n is the normal to the section of the sealing edge in the plane A; F the force experienced by the flap 3 when it is opened; , N is the normal to the sealing edge in the plane passing through the axis of symmetry 9; - a straight line connecting the point of contact of the saddle with the axis of rotation; C friction angle of the pair of saddle - sealing edge of the flap 3; ot is the angle of spherical displacement.
    The direction of the normal n can be determined for each point of the sealing edge 4 in the plane A.
    The forms that allow for the distribution of forces experienced by the valve, in which the absolute value of the forces and their shoulder relative to the rotation axis 8 are minimal, are forms in which the normal N to the sealing edge 4 of the valve 3 on each of the circular sections 1 and 1 located along One and the other side of the plane of symmetry of the valve 3, passing through the axis of rotation 8, intersect the axis of symmetry 9 at two points B and Bi located from the drive axis for a distance not exceeding 0.15 of the diameter of the valve. In the zones located near the plane of symmetry, defined by the sector Y, the points of intersection of the normals to the sealing edge are located between the points B j and Bj of the convergence of the normals of the main surfaces, faceted by the sections (k, (Fig. 6P).
    The shapes of the sealing edge surfaces that meet these conditions can be very different and constitute, for example, the matching of two spherical parts.
    10 and 11 (FIG. 8) with centers at points B and Bt, interconnected by a continuous sequence of elementary spherical surfaces 12, providing a transition from one surface to another; or the conjugation of two conical parts 13 to 14 (Fig. 9) with drain points lying on the axis of symmetry of the saddle, the normals of which passing through the points of contact with the saddle converge at points Bj and B2, and these main surfaces are connected continuous a sequence of transitional conical surfaces 15; or the conjugation of two toroidal surfaces 16 and 17 (Fig. 10) with centers 18 and 19 forming a circle 20 and 21, contact points 22 and 23 between the saddle and the flap and points B j and B 2 which are on the same line, and The relationship between the two tori is performed by a non-successive sequence of transition toroidal surfaces 24.
    FIG. 10 shows a concave toroidal shape, but it can also be a convex toroidal or a conjugation of two bitoroidal surfaces 25 and 26 (Fig. 11), the shape of which consists of two toroidal parts with centers 2730 of circles 31-34 of radius Rj and Rj, while the contact points 35 and 36 between the seat and the flap and the points BI and. B2 are in line. Similarly, the conjugation of two liditroidal surfaces is carried out by a continuous sequence of transient multitoroidal forms.
    The transition of the valve from the open position, in which the flap 3 is parallel to the axis of the passageway of the housing, to the closed position is provided by rotating the flap, ki, at an angle of 90 °, at the end of which the sealing edge of the flap rests against the seat, compressing the gasket and ensuring Thus, the tightness of the channel overlap.
    The proposed shape of the sealing lip provides such a distribution of the forces experienced by the flap, in which their absolute value and shoulder relative to the axis of rotation is minimal, which allows to minimize the friction between the seat and the flap and the torque required to open.
