Description
Technical field
The invention belongs to hydraulic circuit filtration system technical fields, and in particular to a kind of high filtration oil passage filter.
Background technology
Hydraulic oil moves in circles utilization in pipeline, by various hydraulic machineries, often brings some impurity into, so as to meeting
It influences hydraulic pressure or even bring impurity in the machinery of control into, influence equipment performance, so often being added in oil circuit
Filter is fully by hydraulic oil filtering, and the general filtration device structure of existing use is all huger, and filtering simple in structure
Device, because filter area is smaller, so as to be extremely difficult to preferable filter effect, the impurity contained in hydraulic oil is more, to circuit
Equipment has an impact, and can also influence the hydraulic pressure of oil circuit.
The content of the invention
For solution more than technical problem, while device volume is not increased, the filter capacity of filter is improved, the present invention
Provide a kind of high filtration oil passage filter.
To achieve the above object, technical scheme is as follows：
A kind of high filtration oil passage filter is characterized by including cartridge filter, filter seat and filter core, and main points exist
In：The filter seat is concave, and upward, the filter seat is equipped with oil inlet and oil outlet, the cartridge filter to recess
One end is tipped upside down in the recess of the filter seat, and is connected through a screw thread fixation, and the cartridge filter inner wall is equipped with filter core, described
Filter core is end face diafiltration, and side wall enclosed type is equipped with oil pocket, in the filter seat between the cartridge top and cartridge filter inner roof wall
Middle part is equipped with the protrusion for upwardly extending annular, which is equipped with the oil pipe that extends straight up, the oil pipe bottom with it is described
Oil inlet connects, and the top of the oil pipe is flushed with the cartridge top, and is connected with the oil pocket at top, the oil pipe
Tip exterior is arranged with sealing-plug, and the outer wall of the sealing-plug is close to filter core inner wall.
Using more than structure, hydraulic oil enters from oil inlet, is risen to always along oil pipe at the top of oil pipe, then emit flowline to
Surrounding is diffused into oil pocket, because oil pipe top exterior walls are arranged with sealing-plug, the gap of filter core inner wall and oil-pipe external wall is sealed
Extremely, hydraulic oil can only the end face of filter core start to leak down in filter core, finally flowed out again from oil outlet, every section during this
Hydraulic oil can pass through the filtering of entire filter core length and area, achieve the effect that, raising filtering full and uniform to hydraulic oil filtering
Device integral filter ability.
As preferred：The cartridge filter has containing step on the top of itself and filter seat threaded connection section, at this
Step is equipped with external screw thread, and is set with fastening screw nut.Using more than structure, added by engaging of the step with filter
Leakproofness between filter cylinder and filter seat, while fastening screw nut is arranged on top, cartridge filter can be made to be connected more with filter seat
Tightly, prevented loosening from causing to be not tight seal.
As preferred：The filter core is double-deck filter core.Using more than structure, the filtration area of filter core can be effectively increased, is carried
Height diafiltration flow and quality.
As preferred：It is close to the outer wall of the protrusion in the filter core inner wall bottom.Using more than structure, filter core bottom is prevented
It is not fixed and causes sealing performance bad.
As preferred：The filter core inner wall bottom is equipped with O-ring seals with the raised contact surfaces.Using more than structure,
Increasing the sealing effect between filter core and protrusion, flow is too big after preventing hydraulic oil at bottom leaky, and along filter core and protrusion
The face of contact enters in the gap between top oil pipe and filter core, so as to influence oil pressure and oil mass.
As preferred：It is connected between the cartridge filter and filter seat using fine thread.Using more than structure, ensure two
Person more stablizes, while sealing performance is more preferable.
Compared with prior art, the beneficial effects of the invention are as follows：
High filtration oil passage filter provided by the invention, hydraulic oil enter from oil inlet, and oil is risen to always along oil pipe
Tube top portion, then emit flowline and diffused into surrounding in oil pocket, because oil pipe top exterior walls are arranged with sealing-plug, by filter core inner wall
It is shut with the gap of oil-pipe external wall, hydraulic oil can only down be leaked since the end face of filter core in filter core, finally again from fuel-displaced
Mouth outflow, every section of hydraulic oil can pass through the filtering of entire filter core length and area during this, reach and hydraulic oil filtering is filled
Divide uniform effect, improve filter integral filter ability.
Description of the drawings
Fig. 1 is the sectional view of one embodiment of the invention.
Specific embodiment
The present invention is described in further detail in the following with reference to the drawings and specific embodiments.
With reference to high filtration oil passage filter shown in FIG. 1, mainly include cartridge filter 1, filter seat 2 and filter core 3, it is special
Sign is：The filter seat 2 is concave, and upward, the filter seat 2 is equipped with oil inlet 20 and oil outlet 21 to recess,
Described 1 one end of cartridge filter is tipped upside down in the recess of the filter seat 2, and is connected and fixed by fine thread, in the cartridge filter 1
Wall is equipped with filter core 3, and the filter core 3 is percolated for end face, side wall enclosed type, it is set between 3 top of filter core and 1 inner roof wall of cartridge filter
There is oil pocket 12, the interior middle part of the filter seat 2 is equipped with the protrusion 23 for upwardly extending annular, which is equipped with prolongs straight up
The oil pipe 231 stretched, 231 bottom of oil pipe are connected with the oil inlet 20, and the top of the oil pipe 231 is pushed up with the filter core 3
Portion flushes, and is connected with the oil pocket 12 at top, and the tip exterior of the oil pipe 231 is arranged with sealing-plug 232, the sealing
The outer wall of plug 232 is close to 3 inner wall of filter core.
Cartridge filter 1 has containing step 13 on the top of itself and 2 threaded connection section of filter seat, is set on the step 13
There is external screw thread, and be set with fastening screw nut 4, filter core 3 is double-deck filter core.Raised 23 outer wall is close in 3 inner wall bottom of filter core,
3 inner wall bottom of filter core is equipped with O-ring seals 5 with raised 23 contact surface.
The course of work of the present invention is as follows：
The cartridge filter 1 that internal sleeve is equipped with to double-deck filter core 3 is fastened in filter seat 2, and the two is connected by fine thread
Good, the protrusion 23 that middle part is set in filter seat 2 is stretched into the oil pocket 12 in cartridge filter 1, and high pressure oil enters from oil inlet 20, in oil
231 top of oil pipe is risen in pipe 231, into oil pocket 12, and is arranged between 231 top of oil pipe and the outer wall of filter core 3 close
Blocking 232 so hydraulic oil can only enter from the end of filter core 3 inside filter core 3, is percolated downwards, and because the side wall of filter core 3 seals
It closes, so hydraulic oil can only be down percolated inside filter core 3, it is impossible to be flowed directly out from the side wall of filter core 3 into filter core 3 and oil
Gap between pipe 231 ensures that all hydraulic oil can pass through the filtering of entire filter core, improves the filter effect of filter.
Finally it should be noted that foregoing description is merely a preferred embodiment of the present invention, those of ordinary skill in the art
Under the enlightenment of the present invention, on the premise of without prejudice to present inventive concept and claim, expression as multiple types can be made, this
The conversion of sample is each fallen within protection scope of the present invention.
