Claims (1)
Дн / Дв = 1,3... 1,4 ,
где Дн - наружный диаметр прокладки;
Дв - внутренний диаметр прокладки,
а у седла - уплотнителя со стороны установки плоской прокладки выполнен цилиндрический концентрично расположенный выступ с наружным диаметром, образующим с внутренним диаметром прокладки гарантированный кольцевой паз, в котором подвижно размещен свободный конец плоской прокладки, при этом высота выступа меньше половины высоты сечения плоской прокладки.A ball valve containing a housing with inlet and outlet sections for the passage of the medium, communicating with each other through a cavity separating them, a drive shaft with a handle, a ball locking element with a through longitudinal hole and the ability to rotate in a vertical plane at an angle of 90 degrees between the first position of the valve - " open ", in which the opening of the locking element is aligned with the inlet and outlet sections, and the second position of the valve is" closed ", in which the axis of the opening of the locking element is perpendicular to the axis of the housing, two movable, elastic loaded biasing devices saddles - sealants located on both sides of the blocking member with the central concave portions, fully contacting with the valve plug surface. One saddle is installed in a cylindrical bore of the housing, the other in a cylindrical bore of a movable threaded plug with a sealing ring on the outer cylindrical surface, characterized in that the clamping device of the saddle-seal is made in the form of an annular flat gasket of rigid elastic elastomeric material mounted on the side of the supporting end saddles and having a radial section rectangular in shape with an outer diameter equal to the outer diameter of the seat - seal and inner, made in accordance with the ratio:
Dn / Dv = 1.3 ... 1.4,
where Dn is the outer diameter of the gasket;
Dv - the inner diameter of the gasket,
and at the seal seat, on the installation side of the flat gasket, a cylindrical concentrically arranged protrusion is made with an outer diameter forming a guaranteed annular groove with the inner diameter of the gasket, in which the free end of the flat gasket is movably placed, while the height of the protrusion is less than half the cross-sectional height of the flat gasket.
