SET FOR RANDOM MEASUREMENT OF PRODUCTION RATE OF OIL SPRINGS AT GROUP METERING Russian patent published in 1997 - IPC

Abstract RU 2084756 C1

FIELD: oil metering devices, mainly, for oil spots or break of pipe lines. SUBSTANCE: multi-way switch is connected with electric drive and when gas enters its cavity, oil spring is changed over. Liquid meter is placed in operation only in case of operation of flow regulator whose straight-way valve is provided with sleeve-spool valve with multi-disc vane which improves operation of set at low pressures. EFFECT: improved operation at low pressures. 3 cl, 2 dwg
