Simple device for measuring gas-oil ratio

The invention discloses a simple device for measuring gas-oil ratio. The simple device is characterized by comprising a mixed fluid inlet, a mixed fluid outlet, a normally closed solenoid valve I, a normally open solenoid valve I, a normally closed solenoid valve II, a pipeline, a normally open solenoid valve II and a normally closed solenoid valve III, wherein the normally closed solenoid valve I is arranged on the pipeline between the mixed fluid inlet and the mixed fluid outlet; the normally open solenoid valve I is arranged between the mixed fluid inlet and the pipeline, and the normally closed solenoid valve II is arranged at the left end of the pipeline; and the normally open solenoid valve II is arranged between the mixed fluid outlet and the pipeline, and the normally closed solenoid valve III is arranged at the right end of the pipeline. The simple device for measuring the gas-oil ratio is simple in structure, is convenient to manufacture and use and can be widely applied to the test of the effect of gas-oil separators of medium and large engines, combustion gas turbines and test equipment.
