Embodiment Construction

[0026] The present invention will be further described below in conjunction with specific embodiments.

[0027] Such as figure 1 , 2 As shown in, 3, 4, and 5, a fueling gun with a vapor recovery structure includes a vapor recovery fueling gun and a mechanical gas-liquid proportional regulating valve. The valve is sealed and connected. The fuel gas refueling gun includes a barrel 1, an air chamber portion 2, a pull rod portion 3, and a trigger assembly 4. The barrel 1 and the pull rod portion 3 are all connected to the air chamber portion 2. The inlet end of the mechanical gas-liquid proportional regulating valve is sealedly connected with a vacuum flow regulating valve 5, the barrel 1 is sealed with a gas hood 10, and a secondary valve 6 is press-fitted inside the barrel 1. The gas cover 10 is connected with a push rod mechanism, the inner side of the barrel 1 is provided with a return air pipe 7, and the outer side of the barrel 1 is provided with a return air passage 8 communic...

Abstract

The invention relates to an oil gun, in particular to an oil gun with an oil and gas recovery structure. The oil gun comprises an oil and gas recovery oil gun and a mechanical gas and liquid ratio regulating valve, wherein an inlet of the oil and gas recovery oil gun is connected with the mechanical gas and liquid ratio regulating valve in a sealing manner, and both a gun barrel and a pull rod of the oil and gas recovery oil gun are communicated with a gas chamber; the inlet end of the mechanical gas and liquid ratio regulating valve is connected with a vacuum flow regulating valve in a sealing manner; the gun barrel is sleeved with a gas collecting hood in a sealing manner, an auxiliary valve is mounted in the gun barrel in a pressing manner, and the gas collecting hood is connected with a push rod mechanism; a gas returning pipe is arranged on the side face in the gun barrel, and a gas returning channel I communicated with the gas returning pipe is formed in a gun body on the outer side surface of the gun barrel. The oil gun has the advantages of being safe, environmental-friendly and energy-saved and is the necessary equipment of a secondary oil and gas recovery system and a vehicle-mounted oil and gas recovery system of a gasoline station.

Description

Technical field [0001] The invention relates to a fueling gun, in particular to a fueling gun with a vapor recovery structure. Background technique [0002] The Ministry of Environmental Protection of the People's Republic of China initiated the formulation of relevant standards for the on-board refueling vapor recovery system (ORVR) in August 2014. However, the ORVR system is incompatible with the current secondary vapor recovery system of gas stations. With the promotion of gasoline vehicles with the ORVR system, Due to the incompatibility between the existing secondary oil and gas recovery system and the ORVR system, excessive emissions from the gas station will result. The current secondary oil and gas recovery system replaces the fuel nozzle that can identify cars with the ORVR function. When the ORVR fuel nozzle encounters an ORVR car, the A / L will automatically drop to about 0.33. When the automatic flow control valve is working normally, the tank pressure will remain nega...
