Description

Oil absorption filter

Technical field

The utility model is related 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 After time, needing that filter core replace or clean filter core, existing oil absorption filter is both provided with Self-sealing valve, Self-sealing valve generally includes door, and door is arranged in oil absorption filter oil inlet position, and in normal use, filter core is pressed on door On oil inlet is exposed, after removing filter core, effectively it will not be compressed on door, door can be under the action of the elastic member Oil inlet is closed, when replacing filter core, since fuel tank fluid has certain pressure, filter cylinder to have fluid to tear open Dress process causes high effort for, and Self-sealing valve can be in open state in disassembly process, and fluid is easy exudation, 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.

Utility model content

In view of the deficiencies of the prior art, the utility model provides a kind of oil absorption filter, and improved structure advantages of simple can Effectively to reduce the exudation of fluid during the installation process, ensure sealing effect, while installing more convenient.

The utility model provides a kind of oil absorption filter, including cylinder, filter core and skull, and installation is provided on the cylinder Mouthful, the filter core is slidably arranged in cylinder, and the skull is arranged on installing port, and through-hole is offered on the skull, described Be provided in through-hole makes the regulating device of Self-sealing valve opening and closing of fault for pushing against filter core.

The advantageous effect being arranged in this way is：Using the above scheme, 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, to which door exists Oil inlet is closed under the action of elastic component, then opens skull, filter core is taken out, takes out filter core in this way, 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 contributing to cylinder Pressure release after having replaced filter core, fill in filter core convenient for extracting skull, filter core will not also compress door at this time, 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, is slid in cylinder to control filter core, then compress door so that door exposes oil inlet Out so that fluid can enter oil absorption filter, and diversified forms may be used in regulating device here, such as lead to outside skull The mode of push rod ejection filter core is crossed, or by way of being arranged to filter core with cylinder screw to coordinate, while extending to through-hole Rotating member adjusts position of the filter core in cylinder, to compress or discharge door, this oil suction by way of rotation Filter, improved structure advantages of simple can effectively reduce the exudation of fluid, avoid the waste of fluid during the installation process, ensure Sealing effect, while installing more convenient efficient.

It includes push rod that the utility model, which is further arranged to the regulating device, and described push rod one end is provided with for closing The plug of through-hole, the other end are to contradict end, and the conflict end is connect with filter core, and the push rod coordinates with through hole whorl.

The advantageous effect being arranged in this way is：Using the above scheme, it by the way of push rod ejection filter core, is promoted by screw thread Exit realize to filter core compress or far from door, 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 for causing door or filter core influences the service life of setting.

It further includes transition ring that the utility model, which is further arranged to the regulating device, is formed on the skull accommodating Chamber slides between the transition ring setting push rod and filter core and with accommodating cavity and coordinates, and described transition ring one end contradicts end with push rod Connection, the other end is formed with pushes away platform for ejection filter core drive Self-sealing valve.

The advantageous effect being arranged in this way is：Using the above scheme, setting transition ring preferably can carry out ejection to filter core, It may further ensure that sealing simultaneously, prevent fluid from oozing out.

The utility model is further arranged to the transition ring and is circumferentially formed with for limiting transition ring disengaging accommodating cavity Retaining convex rib, the skull is circumferentially formed with boss in accommodating cavity opening, and the retaining convex rib contradicts to be formed with boss Limit to transition ring.

The advantageous effect being arranged in this way is：Using the above scheme, 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 of setting, carries The using effect of high equipment.

The utility model is further arranged to the transition ring and is also extended with positioning convex column into filter core.

The advantageous effect being arranged in this way is：Using the above scheme, by the way that positioning convex column is arranged, convenient for the position to transition ring It is positioned, transition ring is facilitated to carry out ejection to filter core.
