Domain, and in particular to one kind plus one liter of oil one liter of oil gas of recycling make oil tank reach the oil gas recovery rubber tube of equilibrium state.
Background technique
Due to the evaporability of gasoline, each liter of gasoline can volatilize naturally in air for the oil of 600 to 800 times of volumes
Gas.These oil gas can generate many undesirable consequences: 1. dangerous 2. welding, 3. waste of energy.
Gas recovery system for oil i.e. to oil storage tank emptying when can will be in the petroleum vapor recovery to tank truck in oil storage tank.And add
, can be by the petroleum vapor recovery of fuel tank into oil storage tank when oil machine is refueled to automotive oil tank, referred to as secondary oil gas reclaiming system.Gas station
After implementing a petroleum vapor recovery and secondary oil gas recycling, harm caused by oil gas can be effectively controlled, the wave for playing environmental protection, reducing oil
Take and improve the effect of Safety of Gas Station.
Currently, all newly-built, renovating and enlarging storage tank farms, gas station and newly-increased tank truck, it is necessary to according to country
The requirement of oil vapour pollution discharge standard, mandatory requirement just allow to come into operation after installing device for recovering oil and gas and treatment facility.To existing
Some storage tank farms, gas station, tank truck implement oil vapour pollution undertaking treatment within a prescribed limit of time transformation.
The use of petroleum vapor recovery hose is in secondary vacuum auxiliary system, and main is exactly that self priming pump is loaded on fuel charger, together
When use dedicated petroleum vapor recovery refueling nozzle, in refueling process, by oil and gas gas by refueling nozzle, oil gas hose extract out, return
It receives and utilizes.
Existing petroleum vapor recovery hose is vacuum assist type, needs to be assisted using vacuum pump at work, structure is multiple
Miscellaneous, equipment cost is high.The coaxial sebific duct that its structure is made of the fuel hose of conveying fuel oil and the oil gas hose of recycling oil gas,
Oil gas hose is placed in fuel hose, and fuel oil is conveyed between two pipes by annular space.
During the manufacturing, the both ends of oil gas inner tube and the both ends of fuel oil outer tube are fixed on one by special connector
It rises.
Summary of the invention
The utility model provides one kind without using secondary vacuum auxiliary system aiming at the above problem, and structure is simple,
Low-cost balanced type oil gas recovery rubber tube.
In order to realize the above-mentioned purpose of the utility model, the utility model adopts the following technical solution, the utility model packet
Inner tube assembly and outer pipe assembly are included, is cricoid gas channel between inner tube assembly and outer pipe assembly, it is characterised in that: inner tube is total
End is provided with venturi tube, in the thin portion of venturi tube, is provided with towards the check valve inside venturi tube, check valve with
Gas channel is connected.
As a kind of preferred embodiment of the utility model, bend pipe, bend pipe and a twin-tube phase are provided at the check valve
Even, the inlet end of twin-tube is provided with filter.
The utility model has the beneficial effects that the utility model does not use secondary vacuum auxiliary system, oil gas is in gas channel
Interior flowing, after a period of use, the oil gas condensation in gas channel, which forms oil droplet or inner tube assembly, micro oil liquid leakage, makes
Oil liquid is assembled in gas channel；When oiling, it should remain that liquid transfer venturi tube extracts location point and is in lowest point, oil
When liquid is by inside venturi tube, opened under the suction function that check valve is formed in venturi tube, by the oil in gas channel
Liquid sucks back in inner tube assembly, and when non-refuelling, oil liquid does not flow in inner tube assembly and venturi tube, closed check valve, this is practical
It is novel easy to use, it is cheap to existing equipment improvement cost.
