Description
Technical field
The utility model relates to fuel filter technical fields, and in particular to a kind of high efficiency fuel filter.
Background technique
Fuel filter is to be contained in fuel oil on the pipeline being connected between fuel pump and throttle valve body oil inlet for
The solid sundries such as iron oxide, dust remove, prevent fuel system from blocking (especially atomizer), to reduce mechanical wear,
Ensure that engine stabilizer is run, improves reliability.The structure of oil burner generally uses cylindrical housings and the circle with central tube
Shape filter core, the filter material that filtering is provided on filter core are wrapped in the surrounding of central tube, the liquid with impurity in such a way that star folds
Shape fluid passes through filter paper from the periphery of filter core and reaches on the inside of central tube, i.e., clean side, to realize the separation of particle and moisture.
In existing fuel filter, since space limits, the oil inlet of fuel filter in the lower part of fuel filter,
Therefore in application of sub-atmospheric pressure, fuel oil is difficult to fill with filter case, increases so as to cause the pressure difference of fuel filter, filter paper area application
It is limited and waste, whole service life is influenced, also will affect particle filtration efficiency and water separating filter efficiency.
Utility model content
The purpose of this utility model is exactly to provide a kind of filter paper area to overcome the problems of the above-mentioned prior art
The high high efficiency fuel filter of utilization rate.
The purpose of this utility model can be achieved through the following technical solutions: a kind of high efficiency fuel filter, the fuel oil
Filter includes shell and filter core unit, and the filter core unit is immobilized in the shell portion, the housing bottom by fixed bracket
Equipped with fuel oil air inlet, the enclosure interior is equipped with a fuel oil drainage tube, one end of the fuel oil drainage tube and fuel oil air inlet
Mouth connection, the height of the other end are located at the center of filter core cell height, and the side wall of the filter core unit is equipped with for accommodating fuel oil
The notch of drainage tube.Fuel vapor is guided to filter core middle portion location, to make by setting fuel oil drainage tube by the utility model
Obtaining fuel oil can enter from entire filter core face, i.e., filter core area will not be wasted.Simultaneously as being provided with a fuel oil drainage more
Pipe, so the structure to filter core unit is needed to adjust, can accommodate the fuel oil drainage tube.
Preferably, the filter core unit includes upper end cover, lower cover, the filter core being arranged between upper end cover and lower cover
Fan-shaped with the cross section of notch sealing plate, the filter core, two vertical sides of the notch sealing plate and filter core are fixed, institute
It states notch sealing plate to be recessed to filter core side, forms the notch for accommodating fuel oil drainage tube.
Preferably, the central angle of the cross section of the filter core is 200~300 °.
Preferably, the surrounding that the filter core is wrapped in central tube by filter material in such a way that star folds is formed, described
Two of filter material fix vertical side with notch sealing plate.
Preferably, the top of the shell is equipped with gas outlet, and the gas outlet is connected to central tube.
Preferably, the top Yu bottom end of the filter core are solid with upper end cover and lower cover by way of welding or bonding respectively
Fixed connection.
Compared with prior art, the beneficial effects of the utility model are embodied in following several respects:
(1) the design can make the service life of filter elongated, while improve particle filtering and water separating filter efficiency；
(2) the special shape design of filter core unit, is received fuel oil drainage tube very well, and more with shell
Match, to improve the particle filtration efficiency of entire product and the application mileage of water separating filter efficiency and product.
Detailed description of the invention
Fig. 1 is the schematic diagram of the section structure of the utility model；
Fig. 2 is the structural schematic diagram of the utility model filter core unit.
Wherein, 1 is shell, and 2 be filter core unit, and 3 be fuel oil air inlet, and 4 be fuel oil drainage tube, and 5 be gas outlet, and 6 be upper
End cap, 7 be lower cover, and 8 be filter core, and 9 be notch sealing plate, and 10 be notch, is managed centered on 11.
Specific embodiment
It elaborates below to the embodiments of the present invention, the present embodiment before being with technical solutions of the utility model
It puts and is implemented, the detailed implementation method and specific operation process are given, but the protection scope of the utility model is unlimited
In following embodiments.
Embodiment 1
A kind of high efficiency fuel filter, structure is as shown in Figure 1, include shell 1 and filter core unit 2, filter core unit 2 passes through
Fixed bracket is fixed on inside shell 1, and 1 bottom of shell is equipped with fuel oil air inlet 3, is equipped with a fuel oil drainage tube inside shell 1
4, one end of fuel oil drainage tube 4 is connected to fuel oil air inlet 3, and the height of the other end is located at the center of 2 height of filter core unit, shell
1 top is equipped with gas outlet 5.
The structure of filter core unit 2 as shown in Fig. 2, the filter core unit 2 has a notch 10, by upper end cover 6, lower cover 7,
Filter core 8, notch sealing plate 9 surround to be formed, and the inside of filter core unit 2 is equipped with central tube 11, and the central tube 11 and gas outlet 5 connect
It is logical.
Fuel oil enters from the lower part of fuel filter, after the fuel oil drainage tube 4 in shell 1, rises to filter core unit 2
