Description

Technical field:

[0001] The utility model relates to a splash-proof and environment-friendly special oil gun device used in a gas station for refueling motorcycles. Background technology:

[0002] The universal oil guns currently used in gas stations are designed to be suitable for refueling at the fuel tank port of automobiles. Since the oil and gas recovery hole is far away from the fuel tank filling port, the oil gun is exposed to the air, and the oil and gas recovery efficiency is low, causing a large amount of oil and gas to escape from the fuel tank. Employees are exposed to the escaped oil and gas, which not only pollutes the environment of the gas station, but also may pose a risk of explosion.

[0003] At the same time, when the gas station attendant is refueling a motorcycle, since the motorcycle has a small amount of fuel and it is easy to overflow, the gas station attendant needs to concentrate highly on observing the liquid level at the fuel tank opening of the motorcycle. In addition, some women's motorcycles have a shallow fuel tank opening and a horizontal bar in the middle of the opening, which makes it impossible for the fuel gun nozzle to fully extend into the fuel tank opening, and the automatic gun jump function cannot be realized. The fuel gun needs to be suspended in the air and refueling without shifting gears. During refueling, the air collecting hood is far away from the fuel tank opening, and no seal is formed between the fuel gun nozzle and the fuel gun, and the function of the air collecting hood is not played out.

[0004] In addition, some women's motorcycles have a horizontal bar between the fuel tank openings, so the nozzle of the fuel gun cannot be fully inserted into the fuel tank opening, which can easily cause oil spills or splashes when refueling. For this reason, we have developed a special fuel gun device for motorcycles that is splash-proof and environmentally friendly. Summary of the invention:

[0005] The utility model aims to provide a splash-proof and environment-friendly special oil gun device for refueling motorcycles, so as to solve the technical problems in the prior art that the oil tank opening of women's motorcycles is shallow, the nozzle of the oil gun cannot be fully extended into the oil tank opening, which easily causes oil overflow or splashing during refueling, and no seal is formed between the oil tank opening and the oil gun, so the role of the air collecting hood cannot be played to realize the oil and gas recovery function.

[0028] Embodiment 1:

[0029] like Figures 1 to 6 As shown, the utility model provides a splash-proof and environmentally friendly special oil gun device for refueling motorcycles, including an oil and gas recovery refueling gun 100 and an oil and gas recovery device installed at the gun nozzle 101 of the oil and gas recovery refueling gun 100, the oil and gas recovery device includes a fixed base 1 and a gun nozzle jacket 2, one end of the gun nozzle jacket 2 is installed and connected to the fixed base 1, and the fixed base 1 is sleeved on the outside of the gun nozzle 101 of the oil and gas recovery refueling gun 100, and is characterized in that: the gun nozzle jacket 2 is tubular and forms a tube cavity 20 in the middle, and a plurality of oil and gas recovery holes 202 are arranged in the middle section of the gun nozzle jacket 2, and the plurality of oil and gas recovery holes 202 are distributed at intervals along the circumferential direction, and a pressure difference balance hole 201 is arranged on the gun nozzle jacket 2 near one end of the fixed base 1, and the oil and gas recovery hole 202 and the pressure difference balance hole 201 are both connected to the tube cavity 20. By utilizing the front placement of the oil and gas recovery hole 202, when the air collecting hood cannot be sealed when refueling the motorcycle, the oil and gas recovery hole 202 is also located inside the fuel tank, forming a semi-closed refueling environment, allowing the oil and gas in the fuel tank to be fully recovered into the oil and gas tank, achieving very efficient oil and gas recovery. To improve the oil and gas recovery efficiency, the oil and gas recovery hole 202 can more effectively realize oil and gas recovery, effectively recover the oil and gas through the gun nozzle jacket 2, and finally use the pressure difference balance hole 201 to balance the pressure difference, thereby preventing the oil and gas recovery system from sucking in oil products; this not only reduces safety hazards, saves oil resources, but also protects the environment.

[0030] From the perspective of environmental protection, the utility model promotes oil and gas recovery, reduces backsplash or splashing during refueling, and can contribute to pollution reduction and air purification; from the perspective of protecting employee health, the utility model can prevent splashing during refueling, effectively improve oil and gas recovery efficiency, reduce employees' inhalation of oil and gas, and protect employees' health; from the perspective of economic benefits, motorcycle consumption accounts for about 20%, and about 60 million tons of gasoline are consumed each year. If the national oil and gas recovery efficiency loss is estimated at 0.08%, the total annual loss is about 48,000 tons. The use of the technical solution of the utility model can reduce the loss by 0.05%, save 30,000 tons of gasoline, worth about 300 million yuan, and greatly improve the benefits of the enterprise.

[0031] The above-mentioned plurality of oil and gas recovery holes 202 are divided into two rows and staggeredly distributed, and the structure and layout are reasonable, which can improve oil and gas recovery.

[0032] The nozzle jacket 2 is provided with a filter device 3 at one end away from the fixed base 1. When refueling a motorcycle, the filter device 3 of the nozzle plays a role in slowing down the flow rate of the refueling gun, removing bubbles and avoiding splashing. The whole device is easy and quick to disassemble.

[0033] The above-mentioned filtering device 3 includes a rubber ring 4, a filter screen 5 and a gun nozzle cap 6, the filter screen 5 is installed in the through hole 60 of the gun nozzle cap 6, the gun nozzle cap 6 is installed at the end of the gun nozzle jacket 2, and the rubber ring 4 is installed between the gun nozzle jacket 2 and the gun nozzle cap 6 to play a sealing role between the gun nozzle jacket 2 and the gun nozzle cap 6.

[0038] like Figure 2 As shown, an air suction hole 203 is provided on the gun nozzle sleeve 2, and the air suction hole 203 is connected with the tube cavity 20. The position of the air suction hole 203 is consistent with the position of the air suction hole on the oil and gas recovery refueling gun 100, ensuring the normal gun jumping function of the oil and gas recovery refueling gun 100.

[0039] Since the nozzle jacket 2 is connected to the fixed base 1 by threads, it is convenient to disassemble and the oil and gas recovery refueling gun 100 can be returned to the original state when refueling the car.

[0040] The three screw holes 11 of the fixed base 1 are utilized, and three hexagon socket screws are screwed into the three screw holes 11 to connect and install the fixed base 1 on the outside of the gun nozzle 101 of the oil and gas recovery refueling gun 100, so that installation and disassembly are convenient.

[0041] The oil vapor recovery refueling gun 100 is an OPW universal oil gun or a ZVA oil gun.
