Claims (5)

1. 1. A pipeline shut-off device comprising a sealed housing, a shut-off pendulum, a pendulum movement mechanism, a telescopic coupling, spindles with a manual and mechanical drive, the housing is equipped with coaxial connecting flanges for the supplied sections of the pipeline and coaxial seats of the shut-off pendulum, the shut-off pendulum is formed by a blind disk secured to a suspension bracket and suspended in the housing on a Hook hinge with the ability to move along the pipeline axis until the blind disk fits into the seats and across the pipeline axis until the blind disk extends beyond the seats, the telescopic coupling is installed in the housing with the ability to connect the supplied sections of the pipeline with a retractable sleeve, the spindles are mounted on the outer side of the housing, the cylindrical shanks of the spindles are introduced into the housing through gland seals and are connected to the mechanisms of the shut-off pendulum, characterized in that it is equipped with a leading leash of the shut-off pendulum, a cam, an orientation mechanism and a coordinate platform, the leading leash The locking pendulum is secured in the lower part of the blind disk and is equipped with a roller, which is installed with the ability to roll the working surface of the copier and deflect the locking pendulum from the plane of swing, the working surface of the copier is connected with the walls of the guide channels of the orientation mechanism, the coordinate platform includes a movable plate with a drive from a pair of mutually perpendicular spindles and is secured in the housing, the Hooke hinge is secured in the movable plate of the coordinate platform.
2. 2. A pipeline shut-off device according to paragraph 1, characterized in that the pendulum movement mechanism consists of a guide frame and a movable pusher connected to a cylindrical spindle shank, a wedge-shaped groove is made in the pusher, the narrow side of which is directed toward the seats, the leading leash of the shut-off pendulum consists of an axis, a roller and a wedge-shaped shoe, the axis is fixed in a blind disk of the pendulum, the roller is mounted on the axis, the wedge-shaped shoe is directed with its narrow side toward the seats and is rigidly fixed on the axis under the roller, the wedge-shaped shoe is placed in the wedge-shaped groove of the pusher with the possibility of displacement along the walls of the groove during the translational movement of the pusher.
3. 3. A pipeline shut-off device according to one of paragraphs 1, 2, characterized in that the copier is made in the form of a plate with a Δ-shaped opening, and the working surface of the copier is made in the form of walls of the Δ-shaped opening, the top of the Δ-shaped opening is open into the guide channel of the orientation mechanism, the copier is fixed above the pendulum movement mechanism.
4. 4. A pipeline shut-off device according to one of paragraphs 1-3, characterized in that the orientation mechanism is made in the form of a rotary link with a drive from the reciprocating movement of the cylindrical shank of the spindle, the link is made in the form of a prism with two adjacent, concave, cylindrical walls located symmetrically relative to the axis of the link groove, the rotary axis of the rotary link is fixed so that in the extreme positions of the link, one of the concave cylindrical walls of the link and the convex wall of the orientation mechanism form arcuate channels guiding the roller of the drive leash and the blind disk of the shut-off pendulum to one of the seats.
5. 5. A pipeline shut-off device according to one of paragraphs 1-4, characterized in that the roller of the drive leash is made in the shape of an ellipsoid.
