Description
Technical field
This utility model relates to a kind of filter, is specifically related to a kind of for coal mine fully-mechanized mining working
The filter of hydraulic support feed liquor oil circuit.
Background technology
At present, the structure of filter is varied, and the work used by hydraulic pressure system of hydraulic support is situated between
Matter is oil emulsion, owing to underground coal mine condition is relatively severe, unavoidably there is impurity, if not
Can be cleared out in time by these impurity, in system is properly functioning, these impurity can pollute it
Its Hydraulic Elements, thus cause the operation of hydraulic system part ineffective, out of control, even damage.Cause
This, will use filter in coal mine fully-mechanized mining working hydraulic support feed liquor oil circuit, but, existing
The structure design of some filters is unreasonable, thus this filter exists structure complexity, performance not
Stable, assembling defect the most easily.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, it is provided that a kind of structure letter
Singly, filter convenient, stable and reliable for performance is assembled.
For achieving the above object, this utility model uses a kind of filter, including valve body, filter element,
Joint, is provided with valve pocket in described valve body, be provided with filter element in valve pocket, and one end of valve body sets
Being equipped with the liquid outlet being connected with valve pocket, the other end of valve body connects joint, joint and valve body
Between be provided with the first back-up ring and the first O, and on joint, be provided with inlet, joint
It is provided with an annular groove at corresponding inlet on periphery wall, in annular groove, is provided with second
Back-up ring and the second O, described filter element is provided with bending edges, institute on one end of joint
It is provided with positive stop lug boss at corresponding bending edges in the valve pocket stated, and bending edges is installed on positive stop lug boss
And between joint.
The beneficial effects of the utility model are: this filter have simple in construction, assemble convenient,
Advantage stable and reliable for performance, the filter element of this filter uses the mode of card dress to be arranged on valve pocket
In, consequently facilitating filter element and the assembling of valve body, also allow for the replacing of filter element.
Accompanying drawing explanation
Fig. 1 is this utility model example structure schematic diagram.
Detailed description of the invention
As it is shown in figure 1, this utility model embodiment is a kind of filter, including valve body 10,
Filter element 20, joint 30, be provided with valve pocket 11, arrange in valve pocket 11 in described valve body 10
Filter element 20, one end of valve body 10 is had to be provided with the liquid outlet 12 being connected with valve pocket 11, valve
The other end of body 10 connects joint 30, is provided with first gear between joint 30 and valve body 10
Circle 14 and the first O 15, and it is provided with inlet 31 on joint 30, outside joint 30
It is provided with an annular groove 32 at corresponding inlet 31 on perisporium, sets in annular groove 32
Being equipped with the second back-up ring 33 and the second O 34, described filter element 20 is near the one of joint 30
It is provided with bending edges 21 on end, arranges limited in described valve pocket 11 at corresponding bending edges 21
Position boss 13, and bending edges 21 is installed between positive stop lug boss 13 and joint 30.This filtration
The operation principle of device is: when inlet feed liquor, and liquid flows into through joint and carries out inside filter element
Filtering, the liquid after filtration flows into hydraulic control component through liquid outlet, makes control element energy normal
Work.This filter has simple in construction, assembles advantage convenient, stable and reliable for performance, should
The filter element of filter uses the mode of card dress to be arranged in valve pocket, consequently facilitating filter element and valve body
Assemble, also allow for the replacing of filter element.
