Fig. 1 to Fig. 2, which is shown, is integrated with check-valves by plug-in type according to one kind of the preferred embodiments of the present invention
The structural schematic diagram of the environmental-protective filter core of function, this include by the environmental-protective filter core that plug-in type is integrated with return valve function
Filter element body 1 and non-return pipe 4, with reference to Fig. 1, filter element body 1 is conventional filter cartridge construction, filter element body 1 specifically include skeleton, on
End cap 8, lower cover 2 and filter paper 7, skeleton play the role of fixed entire environment-friendly filter element, are calculated according to the demand of different product
Determine its planform and size, skeleton is fixed in the device shell of environmental-protective filter.Filter paper 7 is according to the filter efficiency of product requirement
It is required that selection material, after filter paper 7 is pasted on skeleton, applies a circle reinforced glue, at the 1/3 of filter paper 7 and 2/3 with uniform filter paper 7
Spacing, prevent filter paper 7 heated and machine oil blastic deformation accumulation, to promote service life.Upper end cover 8 and lower cover 2 are distinguished
The top and bottom of filter paper 7 are covered on, need to first pass through the filtering ability of filter paper 7 into the machine oil in the device shell of environmental-protective filter
Enter the inside of filter element body 1.Oil outlet 3 is provided on lower cover 2, enter machine oil inside filter element body 1 finally from
Oil outlet 3 discharges.Preferably, drain oil lug 6 can be integrated on lower cover 2, filter element body 1 is installed on device shell
When interior, the outer wall of drain oil lug 6 is cooperated by the drain oil of sealing ring and device shell to block drain oil, when filter element body 1
When removing, drain oil lug 6 is just detached from drain oil, in order to which remaining machine oil flows back into the oil sump of engine in device shell
In.Furthermore it is also possible to be integrated with a by-passing valve 9 on upper end cover 8, when environmental-protective filter core blocks, in device shell to
The oil pressure of the machine oil of filtering can increase, and when reaching certain pressure value, just the active force of by-passing valve 9 can be overcome to make by-passing valve 9
It opens, allowing filtered machine oil to need not move through filter paper 7 just can enter directly into filter element body 1, then flows back in engine and make
With avoiding being damaged in engine because there is no machine oil.
It continues to refer to figure 1, the lower cover 2 of filter element body 1 is upward convex to be equipped with a sleeve 5 being located in filter element body 1, and covers
The inner hole of cylinder 5 is connected with the oil outlet 3 of filter element body 1, and sleeve 5, filter element body 1 and this three of oil outlet 3 are coaxial point
Cloth.Preferably, the lower cover 2, oil outlet 3 and sleeve 5 of filter element body 1 are integrally formed.It can be the downward projection of lower cover 2
There is an oil outlet lug, oil outlet 3 is opened on oil outlet lug, and lower cover 2 is upward convex equipped with sleeve 5, non-return pipe 4
It is coaxially distributed with oil outlet lug.The lower end of non-return pipe 4 is inserted into the inner hole of sleeve 5, and the upper end, which extends upwardly to, is higher than set
Cylinder 5, it is preferable that non-return pipe 4 is linear cylindrical tube.The lower end of non-return pipe 4 is connect by way of grafting with sleeve 5, energy
It is enough to be convenient for carrying out disassembling, assembling and replacing to non-return pipe 4, with convenient to use.The outside wall surface of the lower end of non-return pipe 4 is interior with the inner hole of sleeve 5
Cooperation is sealed by sealing element between wall surface, the machine oil entered in filter element body 1 needs first to flow from the upper end of non-return pipe 4
Enter into non-return pipe 4, could be discharged from oil outlet 3.Preferably, sealing element is O-ring seal, the inner hole of sleeve 5 it is interior
The upper and lower part of wall surface is each provided with an O-ring seal.It is further preferred that the lower end of the inner hole of sleeve 5 is convexly equipped with one
The lower end of limited step, non-return pipe 4 is held in the palm on limited step, and limited step is used for Auxiliary support non-return pipe 4, and in installation non-return
Positioned when pipe 4, be also convenient for the inner diameter size of non-return pipe 4 to be arranged in this way it is identical as the internal diameter of oil outlet 3 so that the two
Inner hole can be completely to just.
As shown in Figure 1, after engine normally starts work, into the machine oil in the device shell of environmental-protective filter through filter paper
It is entered after 7 filtering in filter element body 1, during machine oil persistently inputs, the machine oil liquid level 9 in filter element body 1 can be protected
The upper end higher than non-return pipe 4 is held, so that it is in non-return pipe 4 and outside from oil outlet 3 so that filtered machine oil is continued into
Discharge.And as shown in Fig. 2, after engine stop, when to be disposed to machine oil liquid level 9 low for the machine oil entered in filter element body 1
When the upper end of non-return pipe 4, machine oil just stops flowing, and machine oil can not enter back into non-return pipe 4, so that remaining machine
Oil cannot be discharged from oil outlet 3 again, and remaining machine oil just stops flowing in pipeline, to guarantee to moisten after engine is shut down
Pipeline in sliding system is reserved with certain machine oil, and dry friction phenomenon occurs in lubricating system after starting engine to avoid next time,
Achieve the purpose that protect engine and promotes service life of aeroengine.The utility model have structure it is simple, it is firm, at low cost and
The advantages of being not take up exceptional space will not influence oil flow rate, and non-return pipe can be arranged to according to the demand of different product
Different height and caliber, so that the engine oil storage capacity reserved in lubricating system reaches the requirement of design.The utility model is excellent
Selection of land, the upper end of non-return pipe 4 extend upwardly to the half of the height of the filter element body 1 at 2/3rds.
The description of the aforementioned specific exemplary embodiment to the utility model is in order to illustrate and illustration purpose.These
Description is not wishing to for the utility model to be limited to disclosed precise forms, and it will be apparent that according to the above instruction, can carry out
It is many to change and change.The purpose of selecting and describing the exemplary embodiment is that explaining the specific principle of the utility model
