Specific embodiment
With reference to the accompanying drawing, specific embodiment of the present utility model is described in detail, it is to be understood that this is practical
Novel protection scope 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 a kind of environmental protection for being integrated with return valve function according to the preferred embodiments of the present invention
The structural schematic diagram of filter element, the environmental-protective filter core for being integrated with return valve function include 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, upper end cover 7, lower cover 2 and
Filter paper 6, skeleton play the role of fixed entire environment-friendly filter element, according to its determining planform of the demand of different product calculating and greatly
Small, skeleton is fixed in the device shell of environmental-protective filter.Filter paper 6 requires selection material, filter paper 6 according to the filter efficiency of product requirement
After pasting on skeleton, a circle reinforced glue is applied at the 1/3 of filter paper 6 and 2/3, with the spacing of uniform filter paper 6, prevent filter paper 6 by
Heat and machine oil blastic deformation are accumulated, to promote service life.Upper end cover 7 and lower cover 2 be covered on respectively filter paper 6 upper end and
Lower end, the filtering for needing to first pass through filter paper 6 into the machine oil in the device shell of environmental-protective filter can just enter in filter element body 1
Portion.Oil outlet 3 is provided on lower cover 2, the machine oil entered inside filter element body 1 is finally discharged from oil outlet 3.It is preferred that
Ground can be integrated with drain oil lug 5, when filter element body 1 is installed in device shell, the outer wall of drain oil lug 5 on lower cover 2
Cooperated by the drain oil of sealing ring and device shell to block drain oil, when filter element body 1 is removed, drain oil lug 5 is just
It is detached from drain oil, in order to which remaining machine oil flows back into the oil sump of engine in device shell.Furthermore it is also possible in upper end cover 7
On be integrated with a by-passing valve 8, when environmental-protective filter core blocks, the oil pressure of machine oil to be filtered can be increased in device shell,
When reaching certain pressure value, the active force of by-passing valve 8 just can be overcome to open by-passing valve 8, filtered machine oil is allowed to be not required to
It just can be entered directly into filter element body 1 through filter paper 6, then flow back in engine and use, avoided in engine because without machine
Oil and be damaged.
It continues to refer to figure 1, non-return pipe 4 is located in filter element body 1, it is preferable that non-return pipe 4 is linear cylindrical tube, only
Return pipe 4 can be coaxial distribution with filter element body 1 between the two.The lower end of non-return pipe 4 is set to the lower cover 2 of filter element body 1
On, and non-return pipe 4 is connected with the oil outlet 3 of filter element body 1, the machine oil entered in filter element body 1 needs first from non-return pipe 4
Upper end be flowed into 4 in non-return pipe, could be discharged from oil outlet 3.Preferably, the lower cover 2, oil outlet 3 of filter element body 1
And non-return pipe 4 is integrally formed, to improve structural strength.It can be that lower cover 2 is downwardly convex to be equipped with an oil outlet lug, it is fuel-displaced
Hole 3 is opened on oil outlet lug, and lower cover 2 is upward convex equipped with non-return pipe 4, and non-return pipe 4 is coaxially distributed with oil outlet lug,
And the internal diameter of non-return pipe 4 is identical as the internal diameter of oil outlet 3.
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 6 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 utility model has structure simple, firm, at low cost and not
The advantages of occupying exceptional space, will not influence oil flow rate, and non-return pipe can be arranged to not according to the demand of different product
Same height and caliber, so that the engine oil storage capacity reserved in lubricating system reaches the requirement of design.The utility model is preferred
Ground, 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
And its practical application, so that those skilled in the art can be realized and utilize a variety of different examples of the utility model
Property embodiment and various chooses and changes.The scope of the utility model is intended to by claims and its waits similar shapes
Formula is limited.
