Wherein, 1 is nozzle to be tested, and 2 is gas liquid ratio adapter, and 3 is nozzle nozzle, and 4 is connecting hose, 5 three-way pieces, and 6 is test oil drum, and 7 is spinner-type flowmeter, and 8 is pressure vacuum gauge.
Embodiment
Below in conjunction with the drawings and specific embodiments, the specific embodiment of the present invention is described further:
As Figure 1-3, a kind of Portable oil-gas reclaims gas liquid ratio proving installation, comprise test oil drum 6 and connecting hose 4, test oil drum 6 is connected with gas liquid ratio adapter 2, the petroleum vapor recovery mouth of gas liquid ratio adapter 2 is connected with pressure vacuum gauge 8 by connecting hose 4, pressure vacuum gauge 8 is connected with spinner-type flowmeter 7 and flow control valve, the greatest measure scale end of spinner-type flowmeter 7 connects pressure vacuum gauge 8, the other end of spinner-type flowmeter 7 is connected with pipeline, pipeline is provided with vacuum pump, and the other end of vacuum pump is communicated with air; Pressure vacuum gauge 8 adopts three-way piece 5 to connect, and is used for reading vacuum tightness size in pipe.
Spinner-type flowmeter 7 comprises indicator, float and tapered tube measuring chamber, gas flows through tapered tube measuring chamber from bottom to top, the gas push float movement flowed through, fluid flow and float the lifting height circulation area of flowmeter (namely with) also exist certain proportionate relationship.Utilize the principle of work of spinner-type flowmeter and feature to judge the positive reverse direction flow of oil gas, namely the direction of motion of the float of flowmeter is oil gas circulating direction.
Spinner-type flowmeter 7 is for being threaded.Spinner-type flowmeter 7 with connecting hose 4 for pagoda mouth is connected.
The gas that vacuum pump extracts first flows through spinner-type flowmeter 7, pressure vacuum gauge 8, then enters nozzle petroleum vapor recovery hole.When stablizing from spinner-type flowmeter 7, measured gas flow and fuel charger refuel the ratio of ratio of flow and are claimed gas liquid ratio, detected, can understand the petroleum vapor recovery effect of gas recovery system for oil by gas liquid ratio.The computing formula of gas liquid ratio is:
