A first fueling pipeline 4 is installed at the front end of the first quick connector 3. The first fueling pipeline 4 is clamped to the first quick connector 3 through a first plug connector 5. A terminal pipe 6 is fixedly connected to the rear end of the oil and gas recovery flame arrester 1. An adsorption assembly 7 is fixedly installed on the outer side of the terminal pipe 6. A connecting pipe 8 is fixedly connected to the rear end of the terminal pipe 6. A second plug connector 9 is fixedly connected to the rear end of the connecting pipe 8. A second fueling pipeline 10 is installed at the rear end of the second plug connector 9. The second fueling pipeline 10 is clamped to the second plug connector 9 through a second quick connector 11.

[0025] First, an alarm 101 and a data transmitter 102 are respectively fixedly installed on the outer side of the oil and gas recovery flame arrester 1. A display 103 is fixedly installed at the top of the alarm 101. An oil and gas monitor 201 is fixedly installed on the outer side of the front-end pipe 2. The oil and gas recovery flame arrester 1 is used for measuring the oil and gas recovery and blocking the combustion of oil and gas. The oil and gas monitor 201 is used for monitoring the oil and gas flow rate at the air inlet of the front-end pipe 2. Among them, both the oil and gas recovery flame arrester 1 and the oil and gas monitor 201 are electrically connected to the display 103, and the monitored data information is displayed through the display 103, which is convenient for the staff to view the relevant data information. The monitored data information can be sent to the oil and gas recovery monitoring system in the gas station control room through the data transmitter 102.

[0026] Furthermore, the first quick connector 3 and the second quick connector 11 have the same structure, and the first plug connector 5 and the second plug connector 9 have the same structure. The first quick connector 3 and the first plug connector 5 can be quickly disassembled and separated. The second quick connector 11 and the second plug connector 9 can also be quickly disassembled and separated in the same way, which is convenient for quickly disassembling and assembling the oil and gas recovery flame arrester 1 with the first fueling pipeline 4 and the second fueling pipeline 10. At the same time, the first plug connector 5 on the first fueling pipeline 4 can be inserted into the second quick connector 11 inside the second fueling pipeline 10, so that the first fueling pipeline 4 and the second fueling pipeline 10 can be quickly docked without affecting the fueling work of the fuel dispenser.

[0027] Then, a connection groove 301 adapted to the first plug 5 is provided inside the first quick connector 3.

During this process, the first plug 5 will first squeeze a plurality of clamping balls 305 into the inside of the activity groove 307. After the first plug 5 is completely inserted, release the movable sleeve 303, so that a plurality of clamping balls 305 are tightly clamped into the inside of the clamping groove 306, thereby quickly connecting the first fuel filling pipeline 4 and the front end pipe 2. The connecting pipe 8 and the second fuel filling pipeline 10 can be quickly connected by using the same operation method. At the same time, when the first plug 5 is connected to the first quick connector 3, the setting of the first rubber sealing ring 302 can effectively ensure the sealing performance of the connection. When detection and maintenance are required, sliding the movable sleeve 303 can quickly disassemble the oil and gas recovery flame arrester 1. Then, insert the first plug 5 on the first fuel filling pipeline 4 into the second quick connector 11 inside the second fuel filling pipeline 10, so that the first fuel filling pipeline 4 and the second fuel filling pipeline 10 can be quickly docked without affecting the fuel filling work of the fuel dispenser. By greatly reducing the operation time and downtime, the use convenience is improved.

[0028] Secondly, a second rubber sealing ring 308 is sleeved inside the movable sleeve 303 on the outside of the first quick connector 3.

The adsorption magnets 706 on the inner sides of the adsorption plates 704 can adsorb on the fuel dispenser, and the adsorption direction can be adjusted according to requirements.

[0030] In this embodiment, the implementation scenario is as follows: When connecting the first fuel pipeline 4 and the front end pipe 2, first slide the movable sleeve 303 to compress the spring 304, and then insert the first plug 5 into the inside of the connection groove 301. During this process, the first plug 5 will first squeeze a plurality of clamping balls 305 into the inside of the movable groove 307. After the first plug 5 is completely inserted, release the movable sleeve 303, so that the plurality of clamping balls 305 are tightly clamped into the inside of the clamping groove 306, thereby quickly connecting the first fuel pipeline 4 and the front end pipe 2. Using the same operation method, the connecting pipe 8 and the second fuel pipeline 10 can be quickly connected, so as to connect and install the oil and gas recovery flame arrester 1 between the first fuel pipeline 4 and the second fuel pipeline 10. At the same time, when the first plug 5 is connected to the first quick joint 3, the arrangement of the first rubber sealing ring 302 can effectively ensure the sealing performance of the connection. When detection and maintenance are required, sliding the movable sleeve 303 can quickly disassemble the oil and gas recovery flame arrester 1, and then insert the first plug 5 on the first fuel pipeline 4 into the second quick joint 11 inside the second fuel pipeline 10, so that the first fuel pipeline 4 and the second fuel pipeline 10 can be quickly butted without affecting the refueling work of the fuel dispenser. The whole operation process is simple and convenient. Compared with the existing devices for monitoring the oil and gas recovery of gas stations, the present utility model can greatly reduce the operation time and downtime through the design, thereby improving the use convenience.
