Problems solved by technology
This detection method needs to close the station for testing. After testing the gas-liquid ratio of many gasoline filling guns, the gas-liquid ratio needs to be closed for several hours, which seriously affects the sales and operation of the gas station; After the liquid ratio is tested several times, it is necessary to return to the tank. During the process of returning to the tank, a large amount of VOCs gas will be volatilized into the atmosphere, which will affect the surrounding environment of the gas station.
[0005] Gas-liquid ratio measurement in gas stations is a time-consuming and labor-intensive task. From the perspective of safety and operation, a new and efficient gas-liquid ratio test method is needed to complete the gas-liquid ratio test.

Embodiment Construction
[0031] The present invention will be further described below in conjunction with accompanying drawing.
[0032] figure 1 An apparatus 100 according to one embodiment of the invention is shown. Such as figure 1 As shown, the device 100 includes an analog controller 1 , a refueling gun return pipe 2 , a first branch pipe 3 and a second branch pipe 4 . Wherein, when the analog controller 1 receives the analog refueling signal, it can control the fuel dispenser to simulate refueling. The gas return pipe 2 of the refueling gun is a passage for recovering gas. One end of the first branch pipe 3 is selectively communicated with the gas return pipe 2 of the refueling gun, and the other end is communicated with the storage tank 5 to form a normal gas recovery pipeline. Thereby, in the state of using the refueling gun to refuel normally, the first branch pipe 3 communicates with the gas return pipe 2 of the refueling gun, and the volatile gas can be recovered through the first branc...

The invention provides a device and method for detecting gas-liquid ratio of a refueling gun. The device comprises an analog controller; a refueling gun return pipe; a first branch pipe is selectivelyconnected to the refueling gun return pipe and the first branch pipe is connected with a storage tank; a second branch pipe is selectively connected with the refueling gun return pipe and the secondbranch pipe is connected to the outside; when the analog controller obtains the simulated fueling signal, the refueling gun return pipe is cut off from the first branch pipe and is connected to the second branch pipe. The device can detect the gas-liquid ratio value of each refueling gun without lifting the gun, thereby greatly reducing the workload, reducing the input of manpower and material resources, and effectively ensuring the normal operation of the gas station.
Description
technical field [0001] The invention relates to the technical field of refueling, in particular to a device and method for detecting the gas-liquid ratio of a refueling gun. Background technique [0002] In order to control the emission of volatile organic compounds (VOCs) from gas stations, on June 22, 2007, the State Environmental Protection Administration issued Announcement No. 44, approving the "Emission Standards of Air Pollutants for Oil Storage Depots" and "Emission Standards for Gasoline Transportation Air Pollutants". " and "Gas Station Air Pollutant Emission Standards" and other three standards are the national pollutant emission control standards, which have been implemented since August 1, 2007 and have the effect of compulsory implementation. At present, most gas stations in my country have completed oil and gas recovery and transformation work, which has reduced the pollution of volatile organic compounds to the surrounding environment and improved the intrins...
