Description
Technical field
The present invention relates to a kind of hydraulic machinery field, especially a kind of oil absorption filter.
Background technology
Oil absorption filter primary side is mounted on hydraulic reservoir, and filter core belongs to consumables, is used in filter core certain
, it is necessary to be replaced to filter core or filter core is cleaned after time, existing oil absorption filter is both provided with Self-sealing valve,
Self-sealing valve generally includes door, and door is arranged on oil absorption filter oil inlet position, and in normal use, filter core is pressed on door
On oil inlet is exposed, after filter core is removed, effectively it will not be compressed on door, door can be under the action of elastic component
Oil inlet is closed, when filter core is replaced, since fuel tank fluid has certain pressure, filter cylinder has fluid to tear open
Dress process causes high effort for, and Self-sealing valve can be in opening in disassembly process, and fluid easily oozes out, and causes the wave of fluid
Take, while fluid exudation is be easy to cause so that filter head, which covers, is stained with greasy dirt so that it is painstaking difficult in skull installation process, it is difficult
It is close to install, cause security risk.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of oil absorption filter, improved structure advantages of simple, Ke Yiyou
The exudation that fluid is reduced in installation process is imitated, ensures sealing effect, while installs more convenient.
The present invention provides a kind of oil absorption filter, and including cylinder, filter core and skull, installing port is provided on the cylinder,
The filter core is slidably arranged in cylinder, and the skull is arranged on installing port, and through hole, the through hole are offered on the skull
In be provided with to push against filter core and make the regulating device of Self-sealing valve opening and closing of fault.
The advantageous effect so set is：Using the above program, oil absorption filter is arranged to this form, is needing to tear open
When going out filter core, regulating device is first passed through, control filter core slides in cylinder so that filter core no longer compresses door, so as to which door exists
Oil inlet is closed under the action of elastic component, then opens skull, filter core is taken out, so takes out filter core, the oil in fuel tank
Liquid is not easy to ooze out, and only has a small number of fluid and is taken out of by filter core, convenient for processing, is not easy to pollute skull, while contributes to cylinder
Pressure release, convenient for skull is extracted, after filter core has been replaced, fill in filter core, filter core will not also compress door at this time, so as to door
Oil inlet will not be opened, fluid will not ooze out in fuel tank, then cover skull, and skull is also easily installed at this time, then
Regulating device is adjusted by through hole, so as to which filter core be controlled to be slid in cylinder, then compresses door so that door exposes oil inlet
Out so that fluid can enter oil absorption filter, and diversified forms may be employed in regulating device here, such as lead to outside skull
It crosses the mode of push rod ejection filter core or extends by way of being arranged to filter core with cylinder screw to coordinate, while to through hole
Rotating member by way of rotation, adjusts position of the filter core in cylinder, so as to compress or discharge door, this oil suction
Filter, improved structure advantages of simple can reduce the exudation of fluid effectively in installation process, avoid the waste of fluid, ensure
Sealing effect, while install more convenient efficient.
The present invention, which is further arranged to the regulating device, includes push rod, and described push rod one end is provided with to close through hole
Plug, the other end for contradict end, it is described conflict end be connected with filter core, the push rod and through hole whorl cooperation.
The advantageous effect so set is：Using the above program, by the way of push rod ejection filter core, promoted by screw thread
Or exit and realize compressing or away from door to filter core, it is simple in structure, while plug is set on push rod, can effectively to through hole into
Row closing, prevents liquid from oozing out, while the setting of plug can control the advance distance of mandril, avoid excessively compressing filter core,
The deformation of door or filter core is caused, influences the service life set.
The present invention is further arranged to the regulating device and further includes transition ring, and accommodating cavity, institute are formed on the skull
It states transition ring and sets between push rod and filter core and slid with accommodating cavity and coordinate, described transition ring one end contradicts end with push rod and is connected,
The other end is formed with pushes away platform for ejection filter core drive Self-sealing valve.
The advantageous effect so set is：Using the above program, transition ring is set preferably can to carry out ejection to filter core,
It may further ensure that sealing simultaneously, prevent fluid from oozing out.
The present invention is further arranged to the transition ring and is circumferentially formed with to limit the limit that transition ring departs from accommodating cavity
Position convex ribs, the skull are circumferentially formed with boss in accommodating cavity opening, and the retaining convex rib contradicts to be formed to mistake with boss
Cross the /V of circle.
The advantageous effect so set is：Using the above program, retaining convex rib and boss are set, transition ring can be controlled
Advance distance avoids excessively compressing filter core, causes the deformation of door, transition ring and filter core, influences the service life set, carries
The using effect of high equipment.
The present invention is further arranged to the transition ring and positioning convex column is also extended with into filter core.
The advantageous effect so set is：Using the above program, by setting positioning convex column, convenient for the position to transition ring
It is positioned, transition ring is facilitated to carry out ejection to filter core.

Fig. 1 is the cross section view of the embodiment of the present invention；
Fig. 2 is the partial enlarged view of the embodiment of the present invention；
Fig. 3 is the top view of the embodiment of the present invention.
Specific embodiment
The invention discloses a kind of oil absorption filter it can be seen from Fig. 1 and Fig. 2, including cylinder 1, filter core 5 and skull 2,
Installing port is provided on the cylinder 1, the filter core 5 is slidably arranged in cylinder 1, and the skull 2 is arranged on installing port, institute
It states and through hole 21 is offered on skull 2, being provided with to push against filter core 5 in the through hole 21 makes the adjusting of Self-sealing valve opening and closing of fault
Device, the regulating device include push rod 31 and transition ring 4, and described 31 one end of push rod is provided with to close the plug of through hole 21
32, the other end is formed with accommodating cavity 22, the mistake to contradict end, the push rod 31 and 21 thread fitting of through hole on the skull 2
It crosses circle 4 and sets between push rod 31 and filter core 5 and slid with accommodating cavity 22 and coordinate, the transition ring 4 is circumferentially formed with to limit
Transition ring 4 processed departs from the retaining convex rib 41 of accommodating cavity 22, and the skull 2 is circumferentially formed with boss in 22 opening of accommodating cavity
23, the retaining convex rib 41 contradicts the /V formed to transition ring 4 with boss 23, and described 4 one end of transition ring is contradicted with push rod 31
End connection, the other end is formed with pushes away platform 42 for the drive Self-sealing valve of ejection filter core 5, and the transition ring 4 also extends into filter core 5
There is positioning convex column 43.
The above embodiments are merely a preferred embodiment of the present invention, it is impossible to the interest field of the present invention is limited with this, because
This, the equivalent variations made according to scope of the present invention patent, for example still belonged to using similar technique, the equivalent product of similar structures
