Problems solved by technology

[0002] The oil and gas recovery function of the oil and gas recovery system of the gas station is one of its necessary functions. If the return air of the fuel gun fails or does not meet the standard, it is easy to cause the fuel gun to jump ahead of time or affect the normal adjustment or other fueling failures when refueling. Therefore, the air return function of the refueling gun is usually tested during regular inspections, and the air return function of the refueling gun in the oil vapor recovery system of the gas station is mainly controlled by the oil vapor recovery pump installed in the fuel dispenser. As we all know, the vacuum pump After long-term work, there will be a certain degree of power attenuation or other problems that cause its negative pressure to break down, and the traditional way to check the return air pump is to achieve it by disassembling some parts and reconnecting them. This method It is not only a waste of time, but also when the equipment is repeatedly disassembled and assembled, it is easy to cause the installation gap to become larger and air leakage to occur. Therefore, if it is possible to provide a device that directly integrates the detection function on the refueling gun without repeated disassembly and inspection, and can be visually observed , then the efficiency and convenience of tanker inspection will be greatly improved

Embodiment 1

[0048] Such as Figure 1 to Figure 7 As shown in one of the present embodiments, the self-inspection type oil and gas recovery refueling gun includes:

[0049] gun body 1;

[0050] The gun head 11 is connected to the front end of the gun body 1;

[0051] The handle 14 has an arc-shaped structure and is arranged on the lower side of the gun body 1;

[0052] The handle 2 is located between the gun body 1 and the handle 14 and is used to start the gun body 1 to refuel;

[0053] The gas collection sleeve 12 is set on the tail end of the gun head 11 and is used to collect the oil gas when the gun body 1 is refueled;

[0054] The oil and gas recovery channel 15 is parallel to the handle 14 and is arranged in the handle 14, and its two ends extend to the front end and the tail end of the gun body 1 respectively; the first connecting sleeve 13 is set on the tail end of the gun head 11 and is located Between the sleeve 12 and the gun body 1, the end close to the air collection sleeve...

Embodiment 2

[0073] Such as Figure 8 or Figure 9 Shown, present embodiment is roughly the same as embodiment 1, and its difference is:

[0074] As a second possible implementation of the airflow sensing mechanism, further, the airflow sensing mechanism includes:

[0075] The impeller 9, the L-shaped bending part of the transition connecting pipe 5 is provided with an arc-shaped extension 51 extending away from the oil and gas recovery passage 15, and the impeller 9 is rotatably connected in the arc-shaped extension 51, and is connected by a transition The gas flow in the tube 5 drives the impeller 9 to rotate.

Embodiment 3

[0077] Such as Figure 10 or Figure 11 Shown, present embodiment is roughly the same as embodiment 1, and its difference is:

[0078] As a third possible implementation of the airflow sensing mechanism, further, the airflow sensing mechanism includes:

[0079] The detection end of the negative pressure gauge 10 is connected to the transition connecting pipe 5 .

[0080] In Embodiment 2 and Embodiment 3, the circulation situation and flow rate of oil and gas in the transition connecting pipe 5 can be observed more intuitively through the form of an impeller or a negative pressure gauge, so as to judge the working capacity of the oil and gas recovery pump in the tanker. If the working performance declines, the speed of the impeller will drop greatly or the reading of the negative pressure gauge will deviate slightly, and the staff can make a simple judgment based on this, whether it is necessary to maintain or replace the oil and gas recovery pump.
