Abstract

The utility model discloses a gasoline filter comprising a shell, a cavity and double-layer filter systems. The upper end of the shell is provided with an upper end cover and the lower end is provided with a lower end cover. The upper end cover is provided with a gasoline outlet and the lower end cover is provided with a gasoline inlet. The cavity is located in the shell. Support springs are fixed to the upper end and the lower end of the cavity. The two sides of the cavity are provided with the double-layer filter systems. Through the design of the upper end cover and the lower end cover and the clamping fit between the outer peripheral edges of the upper end and the lower cover and installing grooves of the shell, the sealing effect of the gasoline filter is improved. The double-layer filter systems which are characterized by double-layer filter by filter paper and a high polymer material filter layer are adopted, so that the filter effect is excellent; and the high polymer material filter layer is a polytetrafluoroethylene filter film and thus is high in filterability.

Description

Gasoline filter

Technical field

The utility model relates to auto parts machinery technical field, relates in particular to the gasoline filter of automobile.

Background technique

The major function of gasoline filter is impurity and the moisture in filtering gasoline, and effect shows as on the one hand can reduce the probability that oil nozzle is blocked by impurity, also can guarantee to flow on the other hand the gasoline oil of oil-fired system.So for gasoline filter, most important part is filter core, the bad meeting of filtering effect of filter core causes oil nozzle to be blocked or is oily poor, and therefore, the utility model provides a kind of new technological scheme to address the above problem.

Model utility content

It is a kind of simple in structure that the utility model provides, the gasoline filter of good filtration effect.

The technical solution adopted in the utility model: gasoline filter comprises housing, cavity and double medium filtration system, the upper end of housing is provided with upper end cap, lower end is provided with lower end cap, upper end cap is provided with oil outlet, lower end cap is provided with filler opening, cavity is positioned at housing inner side, and the two ends up and down of cavity are all fixed with supported spring, and the both sides of cavity are all provided with double medium filtration system.

Above-mentioned upper end cap and the outer periphery of lower end cap engage with the mounting groove of housing.

Double medium filtration system comprises filter paper, macromolecular material filter layer and filter cartridge seat, filter cartridge seat comprises lower of the filter core seat of honour and filter core, the filter core seat of honour is fixed on upper wall in housing, lower of filter core is fixed on housing lower inner wall, filter paper and macromolecular material filter layer are fixed between lower of the filter core seat of honour and filter core, and filter paper is positioned at macromolecular material filter layer outside.

Above-mentioned macromolecular material filter layer is teflon filter membrane.

The beneficial effects of the utility model: the design of upper end cap and lower end cap with and outer periphery engage with the mounting groove of housing, strengthened the sealing effect of gasoline filter; The double medium filtration system adopting adopts the double medium filtration of filter paper and macromolecular material filter layer, and filtering effect is good; Macromolecular material filter layer is teflon filter membrane, and filterability is strong.
