Description
Technical field
The utility model relates to a kind of improvement of diesel fuel filter.
Background technology
The effect of diesel fuel filter is to filter out the objectionable impurities and moisture in diesel systems, protects the normal of diesel engine
Work, abrasion is reduced, avoids blocking, improve the diesel engine life-span.To increase the filter effect of diesel fuel filter, some diesel oil
Cleaner employs double-layer filter structure, but because cotton pad can not be set to filter, to the mistake of the precipitation greasy filth in diesel oil etc.
Effect or not ideal is filtered, internal layer filtering of the prior art inconvenience to double medium filtration in addition is changed.
The content of the invention
In view of insufficient existing for background technology, the purpose of this utility model, which is intended to offer one kind, has the vertical filtering of refill
With the dual filtering functions of cotton pad radial filter, good filtration effect, the double-stage filtering diesel fuel filter that can also facilitate cotton pad to change.
The utility model is adopted the following technical scheme that to complete：
Double-stage filtering diesel fuel filter, it is characterised in that：Including paper screen pack, cotton screen pack, central tube and it is fixedly connected
In the vinyl cover up and down of central tube upper and lower side, paper filtration net cover is located at outside central tube, and paper screen pack is rolled by filter paper forms cylinder
Shape, space is left between the ectonexine filter paper of paper screen pack to form the filtration channel of above-below direction, outside the top of paper screen pack
Round to be adhesively fixed between upper vinyl cover with glue, the cylindrical of upper vinyl cover is provided with lower flange, and the cylindrical of lower flange is provided with sealing
Circle, the bottom connection bottom of lower vinyl cover, for cotton screen pack in the space that lower vinyl cover and bottom cross, cotton screen pack is ring
Shape pad shape, upper vinyl cover are provided with fuel feed hole and oil outlet, and fuel feed hole communicates with the upper surface of paper screen pack, and oil outlet is in
The axial hole that heart pipe is provided with communicates with the endoporus of cotton screen pack.
The bottom of lower vinyl cover is provided with some outer blend stops in outer ring, and some inner sealers, inside and outside blend stop combination are provided with inner ring
Centralized positioning, the lower end connection eave tile of outer blend stop are carried out to cotton screen pack afterwards, the bottom is provided with the hook groove of corresponding eave tile, hooks groove
Top bevel transition with the design of size groove width and by hooking groove, one of flexible design of top bevel for hooking groove,
The top bevel of the hook groove forms flexible block in end.
After adopting the above technical scheme, the beneficial effect that the utility model is realized is：1. internal layer filtering uses cotton pad mistake
Filter, it is ideal to the filter effect of the precipitation greasy filth in diesel oil etc., improve filter effect；2. the vertical mistake for passing through paper element filtering
Passage design is filtered, paper element filtering and cotton pad is filtered and can be laid with upper and lower separating type, so cotton pad filtering can be carried out conveniently
Replacing；3. cotton pad is located in the space that lower vinyl cover and bottom cross, and bottom can conveniently be removed and put, so cotton pad also may be used
Convenient take out is changed.
Brief description of the drawings
The utility model has drawings described below：
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the bottom direction view of bottom in Fig. 1.
Embodiment
As illustrated, double-stage filtering diesel fuel filter of the present utility model, including paper screen pack 9, cotton screen pack 11（Cotton
Pad）, central tube 7 and be fixedly connected on the upper vinyl cover 1 of the upper and lower side of central tube 7, lower vinyl cover 10, during paper screen pack 9 is set in
Outside heart pipe 7, paper screen pack 9 is rolled by filter paper forms cylindrical shape, and space is left to be formed between the ectonexine filter paper of paper screen pack 9
The filtration channel of above-below direction, the top of paper screen pack 9 is cylindrical to be adhesively fixed between upper vinyl cover 1 with glue 6, upper vinyl cover
1 cylindrical is provided with lower flange 5, and the cylindrical of lower flange 5 is provided with sealing ring 4, the bottom connection bottom 14 of lower vinyl cover 10, cotton filtering
In the space that net 11 is crossed located at lower vinyl cover 10 and bottom 14, cotton screen pack 11 is ring-type pad shape, upper vinyl cover 1 be provided with into
Oilhole 2 and oil outlet 3, fuel feed hole 2 communicate with the upper surface of paper screen pack 9, the axial hole 8 that oil outlet 3 is provided with by central tube 7
Communicated with the endoporus of cotton screen pack 11.
The bottom of lower vinyl cover 10 is provided with outer blend stop 12 at three in outer ring, and inner sealer 15 at three, inside and outside gear are provided with inner ring
Centralized positioning is carried out after bar combination to cotton screen pack 11, the lower end connection eave tile 13 of outer blend stop 12, the bottom 14 is provided with corresponding
The hook groove 16 of eave tile, hooking groove 16 has the design of size groove width and the transition of top bevel 17 by hooking groove, one of hook groove
The flexible design of top bevel, the top bevel of the hook groove form flexible block 18 in end.When bottom is installed, the big of groove is hooked
Groove width part alignment eave tile makes eave tile enter hook groove, and then rotating bottom makes eave tile enter the sulculus wide portion for hooking groove, at this moment
Flexible block can block eave tile from outside prevents eave tile from leaving hook groove, and when needing to change cotton pad, only need to press flexible block makes bullet
Property block leave limitation to eave tile, then rotating bottom can allow eave tile to return to the vat wide portion for hooking groove, then remove bottom
Lid can carry out the replacing of cotton pad, very convenient.
