Problems solved by technology

[0004] However, during the long-term use of the second spring of the self-sealing valve assembly in this patent, the elasticity of the second spring will weaken, resulting in the failure of the diaphragm in the self-sealing valve assembly to automatically reset, which in turn causes the spool on the ejector spool to refuel. The groove cannot be smoothly engaged with the rolling pin on the self-sealing valve assembly, which affects the refueling effect

Description

technical field [0001] The invention relates to the technical field of refueling equipment, in particular to a refueling gun for oil and gas recovery. Background technique [0002] At present, many gas stations use ordinary self-sealing refueling guns. When the self-sealing refueling gun is refueling, the oil and gas generated in the fuel tank of the car will be released into the atmosphere, which will cause environmental pollution and safety hazards. It is harmful to health and wastes a lot of valuable energy, especially for some automobile fuel tanks with low fuel volume, which accumulate a large amount of volatile oil and gas. The fuel tank not only pollutes the environment of the gas station, but also causes fire hazards, so it is necessary for the recovery of oil and gas, which can not only play a role in protecting the environment, but also avoid waste and realize energy recycling. [0003] At present, the Chinese patent with the publication number of CN 211770278 U d...
