SAMPLE-TAKING DEVICE Russian patent published in 2005 - IPC

FIELD: oil industry.

SUBSTANCE: hollow body of device is actually a fragment of force pipeline at mostly vertical portion of mouth armature. Organ for controlling flow of multi-component gas-liquid substance is made in form of valve mounted on shaft having lesser size, than inner diameter of hollow body. Sample chamber is in form of ring-shaped hollow on hollow body, positioned at same level with valve. Ring-shaped hollow is connected at input to flow of multi-component gas-liquid substance through intake channels, positioned symmetrically to valve rotation axis, and at output - with locking organ. Driving screw mounted on body of locking organ is connected to sample-taking valve with possible mutual rotation and combined axial displacement. Sample-taking valve and shaft with valve are mated with possible synchronous rotation around common axis and relative axial displacement. Working organs of device are positioned immediately near main flow of substance taken as sample to provide for lesser dimensions of device and prevented freezing in winter season.

EFFECT: simplified construction, simplified maintenance.
