DEVICE FOR REMOVING SHUT-OFF BODY OF BALL VALVE WITH TOP CONNECTOR WITHOUT DISCONNECTION FROM PIPELINE Russian patent published in 2023 - IPC F16K5/20 F16K43/00 

FIELD: general engineering.

SUBSTANCE: device for extracting the shut-off element of a ball valve with an upper connector without disconnecting from the pipeline comprises plate 8 and base 10, which are connected by connecting means and an adjusting means, and fasteners are placed in the base. Fasteners are made with the possibility of fixed attachment of the device to upper flange 9 of the body of the ball valve. The connecting means connect base 10 with plate 8, with the possibility of their movement relative to each other. Moving the expanding end of plate 8 relative to seat 2 and expanding seat 2 for subsequent removal of the shut-off valve from the valve. Plate 8 has an expanding end and a connecting end, the shape of the expanding end of plate 8 repeating the shape of valve seat 2, and the expanding end is made with the possibility of adjoining valve seat 2, and the connecting end of plate 8 is connected to the connecting means and the adjusting means. The adjusting means is made with the possibility of changing the angle of inclination of plate 8 by moving the connecting end of plate 8 relative to the base, while more accurately moving the expanding end of plate 8 relative to the 2 and expanding seat 2 for subsequent removal of the shut-off valve from the valve.

EFFECT: creation of a device for extracting the shut-off body of a ball valve with an upper connector without disconnecting it from the pipeline, which makes it possible to simplify and speed up the repair of the shut-off body of a ball valve, due to the possibility of repair without disconnecting from the pipeline.
