Abstract
The invention discloses a petrol filter. The petrol filter comprises a casing, a cavity and two-layer filtering systems. An upper end cover is arranged at the upper end of the casing, a lower end cover is arranged at the lower end, a petrol outlet is formed in the upper end cover, and a petrol inlet is formed in the lower end cover. The cavity is formed inside the casing, a supporting spring is fixed at each of the upper and lower ends of the cavity, and the two-layer filtering systems are arranged on the two sides of the cavity respectively. The petrol filter has the advantages that by means of the design of the upper end cover and the lower end cover and the snapping of the periphery and a casing mounting groove, the petrol filter seal effect is improved; by means of the two-layer filtering systems, that is, the filtering paper and high polymer material filter layer two-layer filtering is used, and accordingly, the filtering effect is outstanding; the high polymer material filter layer two-layer filtering layer is a polytetrafluoroethylene filtering membrane, and the filtering property is high.
Description
Technical field
The present invention relates to technical field of automobile, particularly relate to the gasoline filter of automobile.
Background technique
The major function of gasoline filter is impurity in filtering gasoline and moisture, and effect shows as the probability that can reduce oil nozzle on the one hand and be blocked by impurity, also can ensure the gasoline oil flowing into oil-fired system on the other hand.So for gasoline filter, most important part is filter core, the bad meeting of filtering effect of filter core cause oil nozzle to be blocked or oil poor, therefore, the invention provides a kind of new technological scheme and solve the problem.
Summary of the invention
The invention provides a kind of structure simple, the gasoline filter of good filtration effect.
The technical solution used in the present invention: 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 case inside, 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 seat under the filter core seat of honour and filter core, the filter core seat of honour is fixed on upper wall in housing, under filter core, seat is fixed on housing lower inner wall, filter paper and macromolecular material filter layer are fixed under the filter core seat of honour and filter core between seat, and filter paper is positioned at outside macromolecular material filter layer.
Above-mentioned macromolecular material filter layer is Teflon filtration film.
Beneficial effect of the present invention: design and its outer periphery of upper end cap and lower end cap engage with the mounting groove of housing, strengthen the sealing effect of gasoline filter; Namely the double medium filtration system adopted adopts the double medium filtration of filter paper and macromolecular material filter layer, and filtering effect is excellent; Macromolecular material filter layer is Teflon filtration film, and filterability is strong.
Accompanying drawing explanation
