Description
Technical field
The utility model belongs to hydraulic circuit filtration system technical field, and in particular to a kind of top is percolated type filter.
Background technology
Hydraulic oil moves in circles utilization in pipeline, by various hydraulic machineries, some impurity is often brought into, so that meeting
Hydraulic pressure is had influence on, or even impurity is brought into the machinery of control, equipment performance is influenceed, so often being added in oil circuit
Filter, is fully that the general filtration device structure of existing use is all huger, and filtering simple in construction by hydraulic oil filtering
Device, because filter area is smaller, so that the impurity for being extremely difficult to contain in preferable filter effect, hydraulic oil is more, to loop
Equipment produces influence, can also influence the hydraulic pressure of oil circuit.
Utility model content
To solve above technical problem, while device volume is not increased, the filter capacity of filter, this practicality are improved
It is new to provide a kind of top diafiltration type filter.
To achieve the above object, the technical solution of the utility model is as follows：
A kind of top is percolated type filter, and it is characterized by including cartridge filter, filter seat and filter core, and it is characterized by：
The filter seat is concave, and upward, the filter seat is provided with oil inlet and oil-out, described cartridge filter one end to its recess
Tip upside down in the recess of the filter seat, and be connected through a screw thread fixation, the cartridge filter inwall is provided with filter core, the filter core
It is percolated for end face, side wall enclosed type, middle part in oil pocket, the filter seat is provided between the cartridge top and cartridge filter inner roof wall
Provided with the projection for upwardly extending annular, the projection is provided with the oil pipe extended straight up, the oil pipe bottom and the oil-feed
Mouth connection, the top of the oil pipe is flushed with the cartridge top, and is connected with the oil pocket at top, the top of the oil pipe
Outer cover is provided with sealing-plug, and the outer wall of the sealing-plug is close to filter core inwall.
Using above 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 inwall and oil-pipe external wall is sealed
Extremely, hydraulic oil can only the end face of filter core start in filter core down seepage, finally flowed out again from oil-out, every section during this
Hydraulic oil can pass through the filtering of whole filter core length and area, reach the effect full and uniform to hydraulic oil filtering, improve filtering
Device integral filter ability.
As preferred：The cartridge filter has containing step on its top that section is threadedly coupled with filter seat, at this
Step is provided with external screw thread, and is set with fastening screw nut.Using above structure, the engaging by step with filter was added
Sealing between filter cylinder and filter seat, while being arranged fastening screw nut on top, can be such that cartridge filter and filter seat connects more
Tightly, prevented loosening from causing poorly sealed reality.
As preferred：The filter core is double-deck filter core.Using above 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 raised outer wall in the filter core inwall bottom.Using above structure, filter core bottom is prevented
Not fixing causes sealing property bad.
As preferred：The filter core inwall bottom is provided with O-ring seals with the raised contact surfaces.Using above structure,
Increase the sealing effectiveness between filter core and projection, flow is too big after preventing hydraulic oil at bottom leaky, but along filter core with it is raised
The face of contact enters in the gap between top oil pipe and filter core, so as to have influence on oil pressure and oil mass.
As preferred：Connected between the cartridge filter and filter seat using fine thread.Using above structure, it is ensured that two
Person more stablizes, while sealing property is more preferable.
Compared with prior art, the beneficial effects of the utility model are：
The top diafiltration type filter that the utility model is provided, hydraulic oil enters from oil inlet, risen to always along oil pipe
At the top of oil pipe, then emit flowline and diffused into surrounding in oil pocket, because oil pipe top exterior walls are arranged with sealing-plug, by filter core
The gap of wall and oil-pipe external wall is shut, hydraulic oil can only since the end face of filter core in filter core down seepage, finally again from going out
Hydraulic fluid port flows out, and every section of hydraulic oil can pass through the filtering of whole filter core length and area during this, reach to hydraulic oil filtering
Full and uniform effect, improves filter integral filter ability.
Brief description of the drawings
Fig. 1 is the sectional view of the embodiment of the utility model one.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Top diafiltration type filter with reference to shown in Fig. 1, mainly includes cartridge filter 1, filter seat 2 and filter core 3, its feature
It is：The filter seat 2 is concave, and upward, the filter seat 2 is provided with oil inlet 20 and oil-out 21, institute to its recess
State the one end of cartridge filter 1 to tip upside down in the recess of the filter seat 2, and be connected by fine thread, the inwall of cartridge filter 1
Filter core 3 is installed, the filter core 3 is percolated for end face, side wall enclosed type, it is provided between the top of filter core 3 and the inner roof wall of cartridge filter 1
Middle part is provided with the projection 23 for upwardly extending annular in oil pocket 12, the filter seat 2, and the projection 23 is provided with to be extended straight up
Oil pipe 231, the bottom of oil pipe 231 connects with the oil inlet 20, the top of the oil pipe 231 and the top of filter core 3
Flush, and connected with the oil pocket 12 at top, the tip exterior of the oil pipe 231 is arranged with sealing-plug 232, the sealing-plug
232 outer wall is close to the inwall of filter core 3.
Cartridge filter 1 has containing step 13 on itself and the top that filter seat 2 is threadedly coupled section, 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 the inwall bottom of filter core 3,
The inwall bottom of filter core 3 is provided with O-ring seals 5 with raised 23 contact surface.
The course of work of the present utility model is as follows：
The cartridge filter 1 that internal sleeve is provided with into double-deck filter core 3 is fastened in filter seat 2, and both are connected by fine thread
Good, the projection 23 that middle part is set in filter seat 2 is stretched into the oil pocket 12 in cartridge filter 1, and hydraulic oil enters from oil inlet 20, in oil
The top of oil pipe 231 is risen in pipe 231, into oil pocket 12, and is arranged between the top of oil pipe 231 and the outer wall of filter core 3 close
Blocking 232, so hydraulic oil can only enter inside filter core 3 from the end of filter core 3, diafiltration downwards, and because the side wall envelope of filter core 3
Close, so hydraulic oil can only be down percolated inside filter core 3, it is impossible to flowed directly out from the side wall of filter core 3 into filter core 3 and oil
Space between pipe 231, it is ensured that all hydraulic oil can pass through the filtering of whole filter core, improve the filter effect of filter.
Finally it should be noted that foregoing description is only preferred embodiment of the present utility model, the ordinary skill of this area
