Abstract
The utility model belongs to the field of garden machine parts and agricultural machine parts, and in particular relates to an oil tank cover for fuel evaporation control. The oil tank cover for fuel evaporation control comprises a cover body; wherein an inner thread matched with an oil tank is formed in the lower part of the cover body; a carbon powder chamber is arranged at the upper part of the cover body, and is filled with carbon powder; an oil-gas separation chamber is arranged in the carbon powder chamber; an oil-gas separation device is arranged in the oil-gas separation chamber; an oil-gas hole is formed in the lower part of the oil-gas separation chamber; a gas passing hole communicated with the carbon powder chamber is formed in the upper part of the oil-gas separation chamber; and a water-gas separation layer is designed at the upper part of the carbon powder chamber. According to the oil tank cover for fuel evaporation control, provided by the utility model, when the pressure inside the oil tank is lower than the pressure outside the oil tank, gas outside the oil tank can enter the oil tank; as the carbon powder is arranged inside the ventilating device of the oil tank cover to absorb fuel vapor, the purpose of reducing vapor emission can be achieved, normal working of equipment is not affected, the overall appearance of the power equipment is guaranteed, and convenience is brought for a user to use.
Description
Technical field
The utility model belongs to graden machine and farm machinery accessory field, is specifically related to a kind of fuel evaporation control fuel tank cap.
Background technique
Along with the raising of social productive forces and living standards of the people, increasing industry realizes the mechanization operation.Non-road power equipment is being used aspect afforestation and the mechanized farming widely, and the demand of fuel oil is increased day by day.Ethanol petrol is used in a large number as a kind of New-type fuel, compares with regular gasoline, has added the gasoline of ethanol, and easier evaporation, infiltration impact environment easily, affects the healthy of people.Power equipment in order to guarantee the abundance of fuel oil supply, arranges air-breather in fuel tank cap usually in operation process, to guarantee the balance of fuel tank external and internal pressure, in this case, fuel-steam can be overflowed from air-breather.
The model utility content
The utility model is at above-mentioned requirements, and a kind of fuel evaporation control fuel tank cap that provides.Fuel evaporation control fuel tank cap does not influence overall appearance preventing that gasoline volatilization and fuel tank cap function from uniting two into one, and is easy to use.
The utility model is to realize like this, a kind of fuel evaporation control fuel tank cap, comprise lid, the internal thread that the setting of lid lower inner wall cooperates with fuel tank, lid top arranges toner chamber, toner chamber fills carbon dust, oily vapour separation chamber is set in the toner chamber, oil vapour arranges oily steum separating device in the separation chamber, below, oil vapour separation chamber arranges oily steam vent, and top, oily vapour separation chamber arranges the air passing hole that communicates with toner chamber, toner chamber top design aqueous vapor separating layer, the lid top arranges the ratchet lid, and ratchet covers vent is set.For improving carbon dust absorption, toner chamber arranges partition, and hole, carbon chamber is set on the partition.For fuel tank cap is more attractive in appearance, prevent that the ratchet lid is loosening, the ratchet side of covering arranges trim, and ratchet is set in the trim.For preventing that the gasoline in the fuel tank from directly overflowing, inwall top, lid below arranges seal ring, overflows in order to prevent fuel oil.
Fuel evaporation of the present utility model control fuel tank cap, by vent is set, air passing hole, oily steam vent, when the pressure in fuel tank was lower than the fuel tank external pressure, the fuel tank extraneous gas can enter fuel tank internal.Install carbon dust in the air-breather of fuel tank cap, fuel-steam is absorbed, reach the purpose that reduces discharge vaporization, do not influence the normal operation of equipment simultaneously, guaranteed the overall appearance of power equipment, user-friendly.
Description of drawings
Fig. 1 is the utility model plan view.
Fig. 2 is the A-A sectional view of Fig. 1.
In the accompanying drawing: the 1-lid, the 2-toner chamber, 3-oil vapour separation chamber, 4-oil steam vent, the 5-air passing hole, 6-aqueous vapor separating layer, the 7-vent, 8-cuts off, hole, 9-carbon chamber, 10-carbon dust, 11-ratchet lid, 12-ratchet, 13-trim, 14-seal ring, 15-oil steum separating device.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail; but the utility model is not limited to following mode of execution; any change of making on the present embodiment principle or replacement scheme all fall among the claimed scope of the utility model.
By reference to the accompanying drawings 1 and Fig. 2, a kind of fuel evaporation control fuel tank cap comprises lid, the internal thread that the setting of lid lower inner wall cooperates with fuel tank, lid top arranges toner chamber, and toner chamber fills carbon dust, and oily vapour separation chamber is set in the toner chamber, oil vapour arranges oily steum separating device in the separation chamber, below, oil vapour separation chamber arranges oily steam vent, and top, oily vapour separation chamber arranges the air passing hole that communicates with toner chamber, toner chamber top design steam separating layer, the lid top arranges the ratchet lid, and ratchet covers vent is set.For improving carbon dust absorption, it is characterized in that toner chamber arranges partition, air passing hole is set on the partition.For fuel tank cap is more attractive in appearance, prevent that the ratchet lid is loosening, the ratchet side of covering arranges trim, and ratchet is set in the trim.For preventing that the gasoline in the fuel tank from directly overflowing, be that inwall top, lid below arranges seal ring, overflow in order to prevent fuel oil.
In use, after the fuel oil in the fuel tank uses minimizing gradually, pressure in the fuel tank is lower than the fuel tank external pressure, the fuel tank outside air enters by vent, passing through the aqueous vapor separating layer, enter toner chamber after separating airborne moisture, enter fuel tank through oily steam vent again and make fuel tank interior pressure and fuel tank external pressure balance.When the gasoline in the fuel tank increased because of reason pressure such as temperature risings, the gasoline that volatilizees entered oily vapour separation chamber by oily steam vent.If there is liquid gasoline to enter in the oily vapour separation chamber, gas enters toner chamber by pore behind the oil steum separating device separating liquid gasoline, by the absorption of the carbon dust in the toner chamber, handles by the aqueous vapor separating layer again, odorless gas enters atmosphere by vent, to reach the environmental protection purpose.
In order to make carbon dust absorption more abundant, partition is set in toner chamber, hole, carbon chamber is set on the partition, increase the travel distance of gas in carbon dust.For preventing that the gasoline in the fuel tank from directly overflowing, inwall top, lid below arranges seal ring, overflows in order to prevent fuel oil.
