DEVICE FOR SAMPLING LIQUID FROM PIPELINE Russian patent published in 2017 - IPC G01N1/10 F17D3/10 

FIELD: oil and gas industry.

SUBSTANCE: device for sampling liquid from pipeline includes a through adapter 3, a rotary valve 4 with vent through channel serially installed on a branch 1 of the pipeline 2. A flange 26 is connected to the valve branch pipe, and a screw mechanism 5 for input and output into the pipeline 2 of a sampling tube 6. The movement of the sampling tube is controlled by a flywheel 64. At that a horizontal axis 71 of rotation of the screw mechanism 5 is fixed on a body of the rotary valve 4. Three lugs 42 are mounted on the flange 35 of the screw mechanism body 5, 43 and 44 with longitudinal grooves. The body of the screw mechanism 5 and the body of the rotary valve 4 are provided with cooperating lug surfaces - a projection and a bore.

EFFECT: determination of quality parameters of liquid pumped in the pipelines, simplification of device servicing, reduction of service time, reduction of costs for thereof cleaning and repair, improvement of device operation reliability.
