Comprehensive test system for oil-gas mixed transportation pump valve

The invention discloses a comprehensive test system for an oil-gas mixed transportation pump valve. The system includes an oil-gas mixed transportation by-pass, a one-way valve test by-pass, an adjustment by-path, a circulation by-pass and a measurement control by-pass, wherein the oil-gas mixed transportation by-pass, the one-way valve test by-pass and the circulation by-pass are connected in an end to end manner, and the one-way valve test by-pass and the adjustment by-path are in parallel connection, and the oil-gas mixed transportation by-pass and the one-way valve test by-pass are connected with the measurement control by-pass. The oil-gas mixed transportation by-pass includes a gas channel, an oil channel and a mixed pressurization line, and the gas channel and the oil channel are in parallel connection, and the gas channel and the oil channel are both connected with the pressurization line. A gas flow meter and a liquid flow meter are both communicated with a static mixer. The circulation by-pass has an oil-gas separator communicated with an oil tank of the oil channel. The measurement control by-pass includes a multi-channel data acquiring device and a central processor which are connected with each other, and the multi-channel acquiring device is connected to a first pressure meter, a second pressure meter, a third pressure meter, a gas flow meter and a multi-phase flow meter.
