Specific embodiment
With reference to the accompanying drawing, specific embodiments of the present invention will be described in detail, it is to be understood that guarantor of the invention
Shield range is not limited by the specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " includes " or its change
Changing such as "comprising" or " including " etc. will be understood to comprise stated element or component, and not exclude other members
Part or other component parts.
Fig. 1 to Fig. 2 shows that one kind according to the preferred embodiment of the present invention is integrated with return valve function by plug-in type
Environmental-protective filter core structural schematic diagram, should to be integrated with the environmental-protective filter core of return valve function by plug-in type include filter core
Ontology 1 and non-return pipe 4, with reference to Fig. 1, filter element body 1 is conventional filter cartridge construction, and filter element body 1 specifically includes skeleton, upper end cover
8, lower cover 2 and filter paper 7, skeleton play the role of fixed entire environment-friendly filter element, are calculated and are determined according to the demand of different product
Its planform and size, skeleton are fixed in the device shell of environmental-protective filter.Filter paper 7 is required according to the filter efficiency of product requirement
Material is selected, after filter paper 7 is pasted on skeleton, a circle reinforced glue is applied at the 1/3 of filter paper 7 and 2/3, between uniform filter paper 7
Away from, prevent filter paper 7 heated and machine oil blastic deformation accumulation, to promote service life.Upper end cover 8 and lower cover 2 cover respectively to be set
In the top and bottom of filter paper 7, the filtering for needing to first pass through filter paper 7 into the machine oil in the device shell of environmental-protective filter just be can enter
To the inside of filter element body 1.It is provided with oil outlet 3 on lower cover 2, enters the machine oil inside filter element body 1 finally from fuel-displaced
Hole 3 discharges.Preferably, drain oil lug 6 can be integrated on lower cover 2, when filter element body 1 is installed in device shell,
The outer wall of drain oil lug 6 is cooperated by the drain oil of sealing ring and device shell to block drain oil, is removed when filter element body 1
When, 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 addition,
A by-passing valve 9 can also be integrated on upper end cover 8, when environmental-protective filter core blocks, machine to be filtered in device shell
Oil oil pressure can increase, when reaching certain pressure value, just can overcome the active force of by-passing valve 9 make by-passing valve 9 open, allow without
The machine oil of filtering needs not move through filter paper 7 and just can enter directly into filter element body 1, then flows back in engine and use, and avoids sending out
It is damaged in motivation 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 that lower cover 2 is downwardly convex to be equipped with
One oil outlet lug, oil outlet 3 are opened on oil outlet lug, and lower cover 2 it is upward convex be equipped with sleeve 5, non-return pipe 4 with go out
Oilhole lug is coaxially distributed.The lower end of non-return pipe 4 is inserted into the inner hole of sleeve 5, and the upper end is extended upwardly to higher than sleeve 5,
Preferably, 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, Neng Goubian
In carrying out disassembling, assembling and replacing to non-return pipe 4, with convenient to use.The inner wall of the inner hole of the outside wall surface and sleeve 5 of the lower end of non-return pipe 4
Between cooperation is sealed by sealing element, the machine oil entered in filter element body 1 needs first to be flowed into from the upper end of non-return pipe 4
In non-return pipe 4, it could be discharged from oil outlet 3.Preferably, sealing element is O-ring seal, the inner wall of the inner hole of sleeve 5
Upper and lower part be 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 a limit
The lower end support of step, non-return pipe 4 is set on limited step, and limited step is used for Auxiliary support non-return pipe 4, and in installation non-return pipe
Positioned when 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
It cannot be discharged again from oil outlet 3, and remaining machine oil just stops flowing in pipeline, to guarantee to lubricate after engine is shut down
Pipeline in system is reserved with certain machine oil, and dry friction phenomenon occurs in lubricating system after starting engine to avoid next time, reaches
To protection engine and promote the purpose of service life of aeroengine.The present invention is simple, firm, at low cost with structure and is not take up
The advantages of 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 present invention preferably, non-return pipe
4 upper end extends upwardly to the half of the height of the filter element body 1 at 2/3rds.
The aforementioned description to specific exemplary embodiment of the invention is in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to the above instruction, can much be changed
And variation.The purpose of selecting and describing the exemplary embodiment is that explaining specific principle of the invention and its actually answering
With so that those skilled in the art can be realized and utilize a variety of different exemplary implementation schemes of the invention and
Various chooses and changes.The scope of the present invention is intended to be limited by claims and its equivalents.
