Embodiment Construction

[0026] like figure 1 , figure 2 and Figure 5 As shown, the present invention provides a fuel filter element, including a filter element housing, one end of the filter element housing is an inlet end and the other end is an outlet end, and the inlet end and / or outlet end of the filter element housing are used for filtering The device housing 1 is connected;

[0027] Along the axial direction, the filter element housing includes a media support part 2, a cone-shaped part 3 with a trumpet-shaped cross section and an inlet and outlet part 4 connected in sequence; the diameter of the upper end of the cone-shaped part 3 is smaller than the diameter of its lower end;

[0028] The inner surface of the medium support part 2 is provided with a filter body in an interference-seal fit; the filter element housing at the conical part 3 and the filter body enclose a conical cavity 5;

[0029] The filter body is densely wound by two layers of filter media, and is seamed at the end of the...

Abstract

The invention discloses a fuel filter filtering element which comprises a filtering element shell which comprises a medium supporting part, a taper part and an in-out opening part which are connectedin sequence, and the cross section of the taper part is in a horn shape; a filtering body is arranged on the inner surface of the medium supporting part in an interference sealing fit manner, the filtering body is formed by tightly winding two layers of filtering media, the structures of the two layers of filtering media are the same, and the two layers of filtering media comprise flat-plate filter paper and corrugation filter paper; one end of the corrugation filter paper in the width direction and is flush with the flat-plate filter paper, an interval is reserved between the other end of thecorrugation filter paper and the end of the flat-plate filter paper, and a glue solution pasting layer is arranged at the interval; the closed end of the first layer of filtering medium is flush withthe opening end of the second layer of filtering medium; and an anti-flameout structure is arranged on the position, where the taper part is located, of the filtering element shell. By means of the fuel filter filtering element, engine flameout can be prevented, and the service life of the fuel filter filtering element is prolonged.

Description

technical field [0001] The invention relates to the technical field of vehicle fuel filter systems, in particular to a filter element, a spin-on fuel filter and a molded case fuel filter using the filter element. Background technique [0002] With the continuous improvement of motor vehicle emission regulations, and more and more OEMs and engine manufacturers put forward the target requirements of long-life maintenance mileage, the original folded structure gradually cannot meet the requirements of higher maintenance life. If the dust holding capacity index of the filter element is increased within the same volume, the service life of the fuel filter element can be improved, which not only meets the requirements of national environmental protection regulations, but also greatly reduces the maintenance cost of the vehicle factory and customers, and improves The market competitiveness of corporate brands. The existing fuel filter, whether it is a spin-on fuel filter or a mold...
