Description
Technical field
The utility model is related to a kind of filter, specifically a kind of superposing type filter.
Background technology
Filter is indispensable a kind of device on pumped (conveying) medium pipeline, is typically mounted on pressure reducing valve, relief valve, Ding Shui
The import end equipment of position valve, square work filter and miscellaneous equipment.Filter is by cylinder, stainless steel filtering net, blowdown part, transmission
Device and electrical control division are grouped as.After the filter cylinder of strainer screen, granule foreign is blocked pending water, so not
Disconnected cycle, the particle being retained down is more and more, and the rate of filtration is slower and slower, when needing cleaning, as long as by detachable
Filter cylinder take out, reloaded after processing.
It is also required to use filter in hydraulic system, face is the cleaning for ensureing hydraulic oil in hydraulic system currently on the market
Degree is carried out to the fluid inside hydraulic system and pipeline using high pressure filter, return filter, oil absorption filter mostly
Filtering；High-precision in-line filter is easy to block during the work of reality, causes the ability drop for filtering and leading to oil
It is low, the reduction to the performance of hydraulic system, and cause oil cleanliness completely out of control.
Invention content
The purpose of this utility model is to provide a kind of superposing type filters, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the utility model provides the following technical solutions：
A kind of superposing type filter, including filtering valve body, spool, gland and plug, the gland are connected with filtering valve body
And gland is internally provided with filter core chamber, and filter core, which is mounted on, to be provided with oil inlet, main oil gallery on filter core intracavitary and filter core and go out
Hydraulic fluid port, plug are mounted in gland, are filtered and are provided with filter hole on valve body.
As further program of the utility model：Pressure difference alarm is installed at plug.
As further program of the utility model：Gland, plug and filtering valve body are all made of resistant material making.
Compared with prior art, the utility model has the beneficial effects that：This product reasonable design, installation volume is small, structure
Compact, filtering accuracy is high, and oil filling capacity is strong, and reset pressure is small, and pollutant carrying capacity is strong, and this product introduced the fluid in main oil gallery
Trap valve body, the main oil gallery inside the laggard filter core of oil inlet through the filter core in gland, from the oil outlet of filter core, after medium is discharged
Work hydraulic system after into the board-like hydraulic valve of hydraulic pressure, can with effective solution in working connection filtering accuracy not high, mistake
In the case of filter reliability is insufficient, local filtration is carried out to the higher control valve of required precision, meets it to the clear of hydraulic medium
Cleanliness requirement, largely reduce oil contamination, cleannes it is not high caused by failure, to control valve row at the guarantor of part
Shield, improves its service life, also improves the global reliability of hydraulic system.
Description of the drawings
Fig. 1 is the structural schematic diagram of superposing type filter.
Wherein：1- filters valve body, 2- filter cores, 3- glands, 4- plugs, 5- filter core chambers.
Specific implementation mode
The technical solution of this patent is described in more detail With reference to embodiment.
Referring to Fig. 1, a kind of superposing type filter, including filtering valve body 1, spool 2, gland 3 and plug 4, the gland 3
It is connected with filtering valve body 1 and gland 3 is internally provided with filter core chamber 5, filter core 2 is mounted in filter core chamber 5 and is arranged on filter core 2
There are oil inlet, main oil gallery and oil outlet, plug 4 to be mounted in gland 3, filters and be provided with filter hole on valve body 1.Pacify at plug 4
Equipped with pressure difference alarm.Gland 3, plug 4 and filtering valve body 1 are all made of resistant material making.
The operation principle of the utility model is：The installation steps of this product are as follows：Filter core 2 is packed into gland 3 by the first step
Face；Plug 4 is packed into 3 the inside of gland by second step；Third walks, and gland 3 is connected with filtering valve body 1；People can be according to oneself
Needs choose whether to load onto pressure difference alarm at plug 4.
This product is mounted between integrated package and the board-like hydraulic valve of hydraulic pressure, it is by 3 groups of filtering valve body 1, filter core 2 and gland
At；It is that the fluid in main oil gallery is introduced filtering valve body 1, laggard 2 the inside of filter core of the oil inlet through the filter core 2 in gland 3
Main oil gallery enters after the board-like hydraulic valve of hydraulic pressure above from the oil outlet of filter core 2, after medium is discharged and carries out work to hydraulic system
Make, this product can be not high in working connection filtering accuracy with effective solution, in the case of filtration reliability is insufficient, to required precision
Higher control valve carries out local filtration, meets its cleannes requirement to hydraulic medium, largely reduces fluid dirt
Failure caused by dye, cleannes are not high improves its service life, also improves liquid to control valve row at the protection of part
The global reliability of pressure system.Pressure difference alarm can send out signal by certain difference force, with prompting we replace or
Clean filter core 2.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this practicality is new
The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing in the equivalent requirements of the claims will be fallen
All changes in justice and range are embraced therein.Any reference numeral in claim should not be considered as limitation
Involved claim.
