Description
Technical field
Mechanical equipment, automatic measurement, oiling petroleum vapor recovery.
Background technology
When being leaked between the gas circuit and oil circuit that gas station oil gas recycles oil gun, liquid vapour is carried in the oil gas of recycling
Oil becomes a kind of gas-liquid mixed two-phase fluid, and it is accurate also to be realized to the gas flow in gas-liquid two-phase fluid with regard to the prior art
It measures.
Invention content
The present invention designs sectional area of the sectional area much larger than suction line of small-sized its body plenum of gas-liquid separator,
The position of outlet line is higher than suction line, and gas-liquid mixed two-phase fluid enters after separator changes flow direction along pipeline groove
Strike the inner wall of ontology, kinetic energy weakens after liquid and the attached wall of grit, under fall on body bottom portion, since sectional area becomes larger fluid stream
It is fast slack-off suddenly, (ω=V/F ω flow velocitys, V volume flows, F pipeline sections product), therefore gas part from bottom to top passes through outlet
Pipeline exports, and wherein proportion is more than the grit of gas and liquid continues separation and falls into body bottom portion.It realizes in gaseous fluid
Liquid, grit separation.Liquid has reached predetermined altitude in bottom and sends out a contact letter by floating-ball level switch detection
Number, liquid and grit after separation can be discharged by drain valve, as liquid level meets or exceeds suction line position separation function
It will failure.
Small-sized gas-liquid separator can be used as the preposition of oiling petroleum vapor recovery air circuit flow sensor and vacuum pump inlet end
Pretreatment unit, is mounted on the upstream of petroleum vapor recovery refueling nozzle gas circuit pipeline, the front end of oil gas flow measurement, when petroleum vapor recovery plus
Oil gun gas circuit and oil circuit can separate liquid gasoline when leaking from recycling oil gas, ensure that the accurate of recycling oil gas
It measures, one alarm is exported by floating-ball level switch when liquid gasoline reaches predetermined altitude in the separator when leakage rate increases
Contact signal notice repair, so greatly improves service efficiency and the service life of flow sensor and vacuum pump.Can also equally it make
In other similar operating modes.
Description of the drawings
