Description
Technical field
This utility model relates to a kind of defecator, is specifically related to the fuel filter assembly of a kind of oil-water separation.
Background technology
The world today, one of motor vehicle exhaust emission source becoming atmospheric pollution, by countries in the world, consumer more and more pays close attention to.In order to reduce motor vehicle exhaust emission pollution on the environment, various countries have all carried out necessary guiding and constraint to it in policy, wherein the oxynitride to exhaust emissions has done strict regulation, in order to reach qualified discharge standard, electromotor manufacturer has done every improvement technically, and high-pressure common rail technology is exactly main technological means.Fuel injection amount and injecting time are required for accurately controlling by high-pressure common rail, in the case of engine work, fuel oil all has to filter through oil-water separation and decontamination and re-uses, but occur running out of under oily fault at electromotor, prior art is the most all by other oil circuit directly by fuel delivery electromotor, the fuel oil i.e. supplied be all without filter and oil-water separation, in fuel oil per se with particulate contaminant will enter electromotor, accelerated wear test hole in nozzle；The sub-granule of large quantity of moisture contained in fuel oil produces corrosion and also has a strong impact on electromotor work atomizer, can not meet the requirement that fuel injection amount and injecting time are required for accurately controlling by high-pressure common rail, and the manual pump of existing product is all to rivet on filter block, the most also cannot detachable maintaining.
Utility model content
For problems of the prior art, the purpose of this utility model is that design provides a kind of fuel filter assembly with oil-water separation.
A kind of fuel filter assembly of oil-water separation, including filter element, filter block, filter element middle and upper part is provided with filtration channel, filter element middle and lower part is provided with the passage that discharges water, double-head hollow bolt is set in it is characterized in that filter block, filter element is connected by double-head hollow bolt thread with filter block, it is provided with oil through in the middle part of double-head hollow bolt, described oil through is connected with the inlet valve arranged on filter block, double-head hollow bolt top is connected with the oil outlet arranged on filter block, the inlet valve passage with oil outlet is additionally provided with delivery valve, filter block side arranges manual pump for positioning and controlling inlet valve, delivery valve works.
The fuel filter assembly of described oil-water separation, it is characterised in that arrange below oil outlet and prevent reverse flow valve.
The fuel filter assembly of described oil-water separation, it is characterised in that manual pump and filter block are dismountable structure, and connect by screw is fixing.
The fuel filter assembly of described oil-water separation, it is characterised in that steel screw thread air vent is set on filter block.
The fuel filter assembly of described oil-water separation, it is characterised in that the passage that discharges water arranges level sensor.
The fuel filter assembly of described oil-water separation, it is characterised in that oil through is ring-shaped.
This utility model novel structure, reasonable in design, in the case of electromotor runs out of the non-normal working of oil, use manual pump fuel feeding, and by this fuel oil through filter element filtering, prevent moisture, particulate contaminant to be directly entered electromotor, and have a strong impact on electromotor work, improve high-pressure common rail fuel injection amount and injection accurately controls, increasing the service life of fuel injection nozzle, it is convenient to keep in repair, and improves the flexibility ratio used.

Detailed description of the invention
This utility model is further illustrated below in conjunction with Figure of description.
A kind of fuel filter assembly of oil-water separation, including filter element 2, filter block 6, filter element 2 middle and upper part is provided with filtration channel, filter element 2 middle and lower part is provided with the passage that discharges water, double-head hollow bolt 3 is set in filter block 6, filter element 2 is threadeded by double-head hollow bolt 3 with filter block 6, annular oil through 4 it is provided with in the middle part of double-head hollow bolt 3, described oil through 4 is connected with the inlet valve 7 arranged on filter block 6, double-head hollow bolt 3 top is connected with the oil outlet 5 arranged on filter block 6, the inlet valve 10 passage with oil outlet 5 is additionally provided with delivery valve 8, filter block 6 side arranges manual pump 9 for positioning and controlling inlet valve 10, delivery valve 8 works.
When engine work, inlet valve 10, delivery valve 8 are all closed modes, and fuel oil enters filter element 2 from oil-in 13, through filtration and the oil-water separation of filtration core 2, removing particulate contaminant and moisture, fuel oil directly gives engine oil through oil outlet 5 from double-head hollow bolt 3.When electromotor non-normal working, when i.e. running out of fuel oil, manual pump 9 can only be pressed and carry out manual pump oil work, now, often press with hands, suction by manual pump 9, inlet valve 10 will be opened with delivery valve 8, fuel oil the most just filters through filter element 2, flow to filtration channel to double-head hollow bolt 3 and suck inlet valve 10, then flow out from delivery valve 8, then achieve the goal to engine oil through oil outlet 5, i.e. use above-mentioned structure, ensure under abnormal condition confession oil and normal condition under the quality of oil of confession be the same.Arrange below oil outlet 5 and prevent reverse flow valve 7, blow back into double-head hollow bolt 3 or filter element 2 and can not fully be used through filtering clean oil product to not allow after manual pump oil.Manual pump 9 and filter block 6 are in dismountable structure, and connect by screw 11 is fixing, be provided with the seal gasket preventing leakage of oil, when there is a need to maintenance when, can turn on screw 11, be repeatable utilization compared with rivetting in manual pump 9, and the most convenient.Arranging steel screw thread air vent 12 on filter block 6, the hardness of steel is high, because fuel filter is also required to often exit, the relative aluminum of steel, hardness is the most reliable, is not likely to produce aluminum bits and falls into oil duct and destroy engine work；The passage that discharges water arranges level sensor 1, i.e. when water level accumulation is too much, with regard to automatic alarm, sluices.
