Description
Technical field
The utility model is related to aero-engine daily maintenance field, more particularly to a kind of center oil filtering is washed with closure dress
It sets.
Background technology
The present invention relates to the center oils in aero-engine daily maintenance to filter cleaning, and center oily filter is aero-engine
Adjuster fuel strainer, performance directly affect engine control reliability, influence motor starting characteristic, acceleration
Energy, rotating speed followability etc., engine periodic maintenance require to carry out ultrasonic wave kerosene cleaning to center oily filter.
It is required when the oily filter ultrasonic cleaning of center, before being put into kerosene, it is reliable to ensure that the oil outlet of oily filter blocks, avoids cleaning
When filter disc in attachment or cleaning solution foul enter inside filter core.
In general, blocking oily filter outlet using vinyon cloth or rag, it is then placed in supersonic wave cleaning machine and is cleaned.
And there are many defects for this method, for technical aspect, blocking oily filter using vinyon cloth or rag exports, may
It can block not tight, the foul that filter core cleaning of outer surface gets off is caused to enter inside filter core by cleansing medium；In addition, polyethylene is moulded
Material cloth or rag cleannes are difficult to ensure that blocking oily filter outlet may be by particle, the fiber on vinyon cloth or rag
Equal exotics are brought into inside filter core, and foul is caused to remain in filter core inner surface and clean and be not thorough.From the aspects of efficiency, use
Vinyon cloth or rag block oily filter outlet, and operation is lack of standardization, and workload is larger.
Invention content
The utility model provides a kind of center oil filtering and washes with plugging device, to solve existing for existing method for blocking extremely
A few problem.
In order to achieve the above object, the utility model adopts the following technical solution：
A kind of center oil filtering is washed with plugging device, including：
Handle, one end are bulb form, and the other end is vertically arranged with endoporus, and opens up and extend transversely through on the inner hole wall
First through hole；
Compression bar, one end open up the second through-hole, which is nested in the endoporus of the handle, and described the is passed through by wiredrawn edge pin
The compression bar is connect by one through-hole and second through-hole with the handle, and the other end of the compression bar is provided with limiting plate；
Holder, top offer pilot hole with lower part, and the compression bar passes through the pilot hole of the pedestal upper end；
Holddown spring is nested on the compression bar, and upper end abuts the pilot hole of the holder, and lower end abuts the compression bar
Limiting plate；
Pedestal is adapted with oily filter oil outlet sealing rubber ring, is arranged in the lower end of the holder lower guide hole.
Optionally, annular knurl is set on the bulb surface of described handle one end.
Optionally, the guiding hole length of the holder is more than 3 times of aperture.
Optionally, the holder is more than 5mm with filter disc outer surface distance.
The beneficial effects of the utility model：The center oil filtering of the utility model is washed with plugging device, using spring compression,
Oily filter installation is simple, and pinch seal is reliable during use, the requirement of filter core internal Protection, structure size when meeting oily filter cleaning
It is small, easy to use, quick, cleaning code.
Description of the drawings
The drawings herein are incorporated into the specification and forms part of this specification, and shows and meets the utility model
Embodiment, and for explaining the principles of the present invention together with specification.
Fig. 1 is that the utility model center oil filtering is washed with plugging device sectional view；
Fig. 2 is that the utility model center oil filtering is washed with plugging device general illustration；
Fig. 3 is that the utility model center oil filtering is washed with plugging device scheme of installation.
Specific implementation mode
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.
As shown in Figure 1 to Figure 2, the center oil filtering of the utility model is washed with plugging device, including：Handle 1, compression bar 3, branch
Frame 4, holddown spring 5 and pedestal 6.
Specifically, 1 one end of handle is bulb form, and the other end is vertically arranged with endoporus, and transverse direction is opened up on inner hole wall
Perforative first through hole, it is advantageous on the bulb surface of 1 one end of handle, annular knurl is set, convenient for holding, good operability.
One end of compression bar 3 offers the second through-hole, which is nested in the endoporus of handle 1, and first is passed through by wiredrawn edge pin 2
Compression bar 3 is connect by through-hole and the second through-hole with handle 1, and the other end of compression bar 3 is provided with limiting plate.In the present embodiment, compression bar
3 are connect with handle 1 using wiredrawn edge pin 2, and connection is reliable.
The top of holder 4 offers pilot hole with lower part, and compression bar 3 passes through the pilot hole of 4 upper end of holder；It needs to illustrate
It is that in the present embodiment, the guiding hole length of holder 4 is more than 3 times of aperture, ensures to be oriented to and stablize, in addition, holder 4 and filter disc appearance
Identity distance is from more than 5mm, ensureing when cleaning the not barrier filter of holder 4.
Further, holddown spring 5 is nested on compression bar 3, and upper end abuts the pilot hole of holder 4, and lower end abuts the limit of compression bar 3
Position plate in the present embodiment, replaces wiredrawn edge pin 2, without to handle 1, the reaming again of compression bar 3, being conveniently replaceable when holddown spring 5 is replaced
Spring 5.
In the lower end mounting seat 6 of 4 lower guide hole of holder, pedestal 6 is adapted with oily filter oil outlet sealing rubber ring.
Referring to Fig. 3, the center oil filtering of the utility model is washed with plugging device, when mounted, pull-up handle 1, in holding
