Abstract
The utility model provides a novel fuel filter. The novel fuel filter comprises a shell and a hollow filter element. The novel fuel filter is characterized in that a filtering screen is installed between the shell and the filter element, two ends of the shell, two ends of the filter element and two ends of the filtering screen are respectively connected with an upper cover and a lower cover in a sealing mode. The upper cover is provided with an outer layer oil inlet pipe and an inner layer oil inlet pipe which are respectively installed between the shell and the filtering screen and between the filtering screen and the filter element. A valve is installed between the outer layer oil inlet pipe and the inner layer oil inlet pipe. The outer oil inlet pipe is connected with an oil suction pipe. An oil outlet is formed at the lower cover filter element hollow position. The hole diameter of the filter element is one half to one fifth of the hole diameter of the filtering screen. When the novel fuel filter is used, fuel oil is conducted two layer filtering through the filtering screen and the filter element. The filtering screen and the filter element can filter and separate impurities with different grain diameters. The impurities are remained on two space layers. Impurity distribution thicknesses on the surfaces of the filtering screen and the filter element can be reduced. Accuracy is guaranteed and service life can be prolonged at the same time. When the filtering screen is blocked, the valve can be opened to communicate with the outer layer oil inlet pipe and the inner layer oil inlet pipe. The filter element can bear the filtering function so as to work for a period time, and the service life can be further prolonged.
Description
Technical field
The utility model relates to a kind of automobile fuel oil filter, particularly relates to a kind of fuel filter.
Background technique
Along with domestic automobile industry is flourish, automobile pollution grows to even greater heights, people progressively improve the understanding of automobile, the care and maintenance of automobile also more and more comes into one's own, fuel filter is exactly wherein to safeguard more frequent one, generally just need to change once at 1.5 ten thousand to 20,000 kilometers, what affect its working life is mainly that the uneven impurity of internal vapor oil quality is many.Fuel filter is the necessary parts that guarantee to provide for engine combustion pure fuel oil, its internal structure mainly is made of a filter core, the size of filter core hole has determined filter precision, determining of filter core hole is very crucial, the too little easy obstruction pressure reduction of hole becomes large and uses the life-span short, not only can block oil nozzle after the too large impurity of hole passes through, also can strengthen in-engine carbon deposit, increasing is benefited from life-span people from aspect and is awaited technological improvement when ensureing filter precision at present.
The model utility content
For filter precision and the working life of improving fuel filter, the utility model provides a kind of fuel filter.
The technical solution adopted in the utility model is: a kind of fuel filter, the filter core that comprises housing and hollow, it is characterized in that being provided with filter screen between housing and filter core, the two ends of housing, filter core, filter screen respectively with upper cover, lower cover is airtight is connected, upper cover is between housing and filter screen, be respectively equipped with outer oil inlet pipe and internal layer oil inlet pipe between filter screen and filter core, be provided with valve between outer oil inlet pipe and internal layer oil inlet pipe, outer oil inlet pipe connects fuel sucking pipe, and lower cover filter core hollow position is provided with oil outlet.
Described filter core aperture is 1/2nd to 1/5th of aperture of filter screen.
When the utility model uses, fuel oil is through filter screen and filter core double medium filtration, filter screen and filter core carry out filtering separation to different-grain diameter impurity, impurity is retained on two space layer, has reduced filter screen and cartridge surface Impurity Distribution thickness, can increase the service life when ensureing precision; When filter net jam is obstructed, but the also outer oil inlet pipe of Open valve UNICOM and internal layer oil inlet pipe are born most of filtering function a period of time of working again by filter core and are further increased the service life.
Description of drawings
Fig. 1 is the utility model structural representation;
Number in the figure title: 1 housing; 2 filter cores; 3 filter screens; 4 upper covers; 5 lower covers; 6 outer oil inlet pipes; 7 internal layer oil inlet pipes; 8 valves; 9 oil outlets.
Embodiment
The utility model embodiment as described in Figure 1, this fuel filter is provided with the filter core 2 of housing 1 and hollow, 2 of housing 1 and filter cores are provided with filter screen 3, filter core 2 apertures are 1/3rd of filter screen 3 apertures; The two ends of housing 1, filter core 2, filter screen 3 respectively with upper cover 4, lower cover 5 is airtight is connected, upper cover 4 is respectively equipped with outer oil inlet pipe 6 and internal layer oil inlet pipe 7 at housing 1 and 3 of filter screens, filter screen 3 and 2 of filter cores, outer oil inlet pipe 6 and 7 of internal layer oil inlet pipes are provided with valve 8, valve 8 is by the cock of screw-thread fit on internal layer oil inlet pipe 7, outer oil inlet pipe 6 connects fuel sucking pipe, and lower cover 5 filter core 2 hollow positions are provided with oil outlet 9; Use valve 8 in early stage is closed, fuel oil is entered through filter screen and filter core double medium filtration by outer oil inlet pipe 6 and is flowed out by oil outlet 9, filter screen and filter core carry out filtering separation to different-grain diameter impurity, impurity is retained on two space layer, reduced filter screen and cartridge surface Impurity Distribution thickness, can increase the service life when ensureing precision; When using that the later stage, filter net jam was obstructed, the outer oil inlet pipe of Open valve 8 UNICOMs and internal layer oil inlet pipe, fuel oil is entered simultaneously by outer oil inlet pipe 6 and internal layer oil inlet pipe 7, bears most of filtering function by filter core and works a period of time, can further increase the service life; The utility model is entered and can also be washed away filter screen by downward oily stream by outer oil inlet pipe 6 at fuel oil, makes impurity to lower cover place's accumulation, keeps the unimpeded of the oily stream in filter screen front and back.
When the utility model is implemented, the filter core aperture can be in 1/2nd to 1/5th adjustings of aperture of filter screen, to adapt to different oil products; Valve 8 also can adopt ball valve.
