Description

Technical Field

[0001] The utility model relates to a refueling gun, in particular to a flexible oil and gas recovery refueling gun, belonging to the technical field of refueling equipment. Background Art

[0002] At present, most gas stations use ordinary self-sealing fueling guns, which have the function of automatically closing the oil circuit when the car tank is full. Its structure mainly consists of a gun body, a main valve, a push rod, a switch membrane, a self-sealing rod, a self-control rod, a secondary valve core, and a fuel gun nozzle. Three steel balls are installed in the three holes on the upper end of the self-control rod. The secondary valve seat is provided with small holes along the circumferential direction, which communicate with the upper cavity of the switch membrane through the inclined hole on the gun body; there is an inclined hole on the adapter sleeve, which communicates with the outside world through the air inlet hole and the air inlet nozzle. The inclined hole communicates with the upper cavity of the switch membrane through the inclined hole on the gun body, and the lower cavity of the switch membrane communicates with the outside world through the gap between the gun body and the self-control rod.

[0003] The patent document with the prior art publication number CN111039248A provides an oil and gas recovery refueling gun, including a gun body and a gun frame installed at the bottom of the gun body, a cavity for oil to pass through is formed in the gun body, an oil and gas separation valve assembly and a push rod valve core are arranged in the cavity in sequence, and a self-sealing valve assembly for preventing oil from overflowing is installed on the upper end of the push rod valve core; an oil outlet pipe assembly is arranged at the oil and gas outlet end of the cavity, and the oil outlet pipe assembly includes an oil outlet pipe and a vent pipe; an adapter sleeve connected to the oil outlet pipe is arranged in the cavity, a valve seat is arranged in the adapter sleeve, and a secondary valve core is installed on the valve seat; the adapter sleeve is connected to an oil and gas recovery pipe for recovering oil and gas, and the other end of the oil and gas recovery pipe is connected to the oil and gas separation valve assembly. The oil and gas recovery refueling gun of the present invention has the advantages of light gun body, small oil flow resistance and high oil flow rate, and the oil and gas recovery pipe improves the oil and gas recovery efficiency of the refueling gun when it is working, reduces the leakage probability of the oil gun, and improves air pollution.

[0004] However, when the existing oil and gas recovery refueling gun is in use, the barrel of the oil and gas recovery refueling gun is an integral metal pipe with oil and gas recovery holes and an oil passage inside. When the oil and gas recovery refueling gun is operated by a refueling robot, the oil gun is prone to collide with the oil tank port when inserted into the oil tank port, and the refueling robot does not have a human body perception function, which is prone to danger when a collision occurs. For this reason, we propose a flexible oil and gas recovery refueling gun. Utility Model Content

[0021] An oil and gas recovery hole 9 is opened on the outer surface of the gun barrel 8, and a flexible connecting pipe 10 is fixedly connected to the side of the outer surface of the gun barrel 8 away from the oil and gas recovery hole 9. A fixed sleeve 11 is fixedly connected to the outside of the flexible connecting pipe 10, and an electrostatic conductive metal wire 12 is fixedly connected to the inside of the flexible connecting pipe 10. Example

[0022] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0023] One end of the handle tube 2 is fixedly connected to the mounting tube 3, and one end of the mounting tube 3 is fixedly connected to the butt joint tube 4. By mounting the oil pipe on the butt joint tube 4, it is convenient for workers to transport the oil pipe.

[0024] There are multiple oil and gas recovery holes 9 , and the multiple oil and gas recovery holes 9 are of different sizes and are arranged equidistantly. Oil and gas can be better recovered through the oil and gas recovery holes 9 .

[0025] The gun barrel 8 is made of stainless steel, and the outer surface of the gun barrel 8 is smooth. The gun barrel 8 made of stainless steel is more durable and not easy to rust. Example

[0026] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0027] Two fixing sleeves 11 are provided, and the two fixing sleeves 11 are of the same size. The fixing sleeves 11 enable the flexible connecting pipe 10 to be fixed more firmly and not prone to sliding.
