In fuel tank so that the gas outlet of necking forms negative pressure, and the fuel-steam in fuel tank is drawn onto oil fuel tube through circulation pipe and necking
Interior, fuel-steam is again introduced into fuel tank so that and fuel-steam is recycled utilization, in addition, before necking is connected with circulation pipe,
The gas outlet size of necking can be made to change, to reach regulation oil fuel tube according to the taper size for being actually needed regulation necking
The fuel-steam uninterrupted and the purpose of throttling being inside inhaled into, to adapt to different type of vehicle；The utility model passes through
The recycling of fuel-steam is realized in the setting of circulation pipe, more environmentally-friendly；According to different type of vehicle, different size is changed
Necking, to the purpose for adjusting the fuel-steam uninterrupted being inhaled into oil fuel tube and throttling；The utility model can be applied to
In system with vehicle-mounted petroleum vapor recovery.
The adsorptive pressure of canister can be reduced into fuel tank by circulation pipe circulation oil gas, the fuel tank is provided with oil
Gas control valve, one end of the gas outlet connection blast pipe of oil gas control valve, blast pipe other end connection four-way pipe one end, four-way pipe
The second end connection connecting tube one end, the other end of connecting tube is connected to the air inlet of canister；This design, which is realized, reduces canister
While adsorptive pressure, the recycling of fuel-steam is realized.
In order that fuel-steam is further recycled, weight valve, the weight valve are additionally provided with the fuel tank
Outlet connection escape pipe one end, the three-terminal link of the escape pipe other end and four-way valve；In this design, when in fuel tank
Pressure when exceeding the pressure-bearing of weight valve setting, fuel-steam enters escape pipe along weight valve, the fuel-steam in escape pipe
It is recovered to successively by four-way pipe, circulation pipe and oil fuel tube in fuel tank.
In order to improve the stability of circulation pipe connecting structure, the circulation pipe is by firmware with being connected on the outside of oil fuel tube.
