The invention discloses an automobile concentric oil filling pipe assembly with a nylon pipe. The automobile concentric oil filling pipe assembly comprises an oil filling pipe and an exhaust pipe, thefront end of the oil filling pipe is expanded to form an oil filling end, and the air outlet end of the exhaust pipe is welded and communicated with the oil filling end of the oil filling pipe; a stainless steel oil filling port is welded to the port of the oil filling end in a sealed mode, an anti-overflow sleeve which extends into the port of the oil filling end and is used for preventing fueloil from overflowing during oil filling is integrally formed at the lower part of the oil filling port, an oil outlet is formed in the bottom surface of the anti-overflow sleeve, the oil filling portand the oil filling end are coaxially arranged, and an oil outlet and the oil filling end are eccentrically arranged; a positioning support used for positioning the spatial directions of the oil filling pipe and the exhaust pipe is welded between the oil filling pipe and the exhaust pipe, and the oil filling pipe and the exhaust pipe are integrally assembled through the positioning support to forma nylon pipe assembly used for being connected with a carbon tank to achieve environment-friendly exhaust emission. The automobile concentric oil filling pipe assembly is simple in structure, high inintegration level and smooth in refueling, and adsorbed waste gas can be discharged in an environment-friendly mode.
Description
technical field [0001] The invention relates to the technical field of vehicle accessories, in particular to a fuel filler pipe assembly applied to a fuel tank, in particular to a fuel filler pipe assembly with concentric nylon tubes for automobiles. Background technique [0002] The fuel tank of the car is used to store fuel. In order to facilitate the sealing of the fuel tank, the fuel tank port of the fuel tank will be equipped with a special filling pipe assembly. The traditional filling pipe assembly usually consists of a filling pipe and an exhaust pipe. This filling pipe can discharge the gas in the fuel tank through the exhaust pipe when refueling, so as to ensure the smoothness of refueling. Because some fuel oil (mainly gasoline) is easy to generate oil vapor at room temperature, which causes waste, carbon canisters are now used to realize the utilization of adsorbed oil and gas, and the exhaust gas after absorbing oil and gas is discharged through the exhaust pipe...
