Filling pipe with a leak alarm function

Abstract

The invention discloses a filling pipe with a leakage alarm function, which includes a filler tube body and a filler port, A fuel hose is fixed at the tail end of the fuel pipe body, an electroplatedcolored zinc layer is arranged on the outer surface of the fuel pipe body, a PE powder layer is sprayed on the electroplated colored zinc layer, and a vent pipe and a return pipe are connected on thefuel inlet, and the vent pipe and the return pipe are fixed beside the fuel pipe body along the direction of the fuel pipe body; A mounting bracket is arranged on the filling port, and a DMTL leak detection valve is fixed on the mounting bracket. The invention has a simple structure, has colored zinc plating layer and PE powder layer arranged on the outer surface of the oil filling pipe body whichcan improve the corrosion resistance and stone impact resistance of the oil filling pipe, and furthermore, the safety of the oil filling pipe is improved through the setting of the DMTL leakage detection valve.

Description

technical field [0001] The invention relates to the field of vehicle accessories, in particular to a filling pipe with a leakage alarm function. Background technique [0002] With the rapid development of my country's automobile industry and the continuous improvement of people's living standards, more and more cars have entered our families, and the demand for family cars has soared. Cars are usually fueled with gasoline or diesel oil and are equipped with a fuel tank. In order to facilitate the sealing and refueling of the fuel tank, the filling port of the fuel tank is provided with a special filler pipe. The filling pipes in the prior art are generally made of hard materials such as iron parts or steel parts. Because the interior space of the car is narrow and tortuous, this brings a lot of trouble to the manufacture of the filling pipes; The filling pipe made of high quality material then has the disadvantages of being troublesome to be connected with the filling port,...

Problems solved by technology

The filling pipes in the prior art are generally made of hard materials such as iron parts or steel parts. Because the interior space of the car is narrow and tortuous, this brings a lot of trouble to the manufacture of the filling pipes; The filling pipe made of high-quality materials has the disadvantages of troublesome connection with the filling port, and the connection is not firm.

Furthermore, when some fuel pipes are filled with fuel, the oil intake and return air go all the way, which will make the fuel filling not smooth enough, and the phenomenon of fuel choking is prone to occur, so there is still room for improvement in the existing fuel pipes.
