LIQUID FROM THE PIPELINE SAMPLING DEVICE Russian patent published in 2018 - IPC G01N1/10 

FIELD: measuring equipment.

SUBSTANCE: invention is intended for the fluid from a pipeline sampling. Sampling device contains the sampling tube with vertical, radial and input openings, the sampling tube raising and lowering mechanism with a screw. Sampling tube raising and lowering mechanism screw is located inside the chamber, at that, the screw upper end is made with three coaxially arranged cylindrical protrusions. Upper protrusion is stationary located in the flywheel cylindrical recess. Lower protrusion is located in the disk opening, tightly fixed between the chamber upper flange and the cover. Locking valve spool has the shape of a hollow cylinder with cylindrical protrusion on the side wall upper part and with a two-stage cylindrical recess. In the sampling tube lower extreme position, in the sleeve cavity, hermetically and with the ability to move up, the locking valve hollow cylinder is located. To the locking valve hollow cylinder protrusion side wall the three identical planks are fixed, located at the same distance from each other and directed upwards. On each plank upper end, a roller is mounted with possibility of rotation, by the side wall interacting with the chamber inner wall.

EFFECT: technical result is enabling the device reliability and durability.
