The whole filter element group spare of filter adopts the cartridge formula, this structure operating space in the pit with the institute under the use tools limited condition, can greatly improve the convenience of maintaining. It is applicable to the comprehensive working face hydraulic support that adopts in colliery.
Description
Technical field
This utility model relates to a kind of filter, refers in particular to a kind of coal mine hydraulic supporting high precision high flow rate filter.
Background technology
Chinese patent once disclosed a kind of coal mine hydraulic supporting automatic backwashing filter (CN201420513880), including: valve body, connecting plate, electromagnetic priority valve, it is characterized in that: on described valve body, have two identical filter chambers and two identical working chambers, it is provided with inlet in the middle of two filter chambers, it is provided with liquid outlet in the middle of two working chambers, valve body both sides also have sewage draining exit, filter element and big plug are connected into assembly and are arranged on filter chamber, core assembly is arranged on working chamber, core assembly is by swivel nut, valve pocket, PEEK seal receptacle, differential piston, valve rod, spring forms, swivel nut and valve pocket are fixed by screw attachment, electromagnetic priority valve uses screw to be fixed on connecting plate, connecting plate uses screw to be fixed on valve body, it is applicable to coal mine fully-mechanized mining working electrohydraulic control system more.
Chinese patent once disclosed a kind of mining automatic backwashing filter (CN201420156986), including: valve body, rebound, electromagnetic priority valve, two identical die cavities it are provided with on the right side of described valve body, two identical core assemblies are installed, it is provided with a die cavity on the left of valve body and filter element is installed, valve body front is provided with inlet opening P mouth and returns liquid R1 mouth, and rapid connector component is installed at the back side, is provided with mudhole R2 mouth in rapid connector component.Electromagnetic priority valve is linked together by rebound and valve body and is parallel to valve body.This utility model reduces the three-dimensional dimension of automatic backwashing filter, solves due to the problem of hydraulic support narrow space backwash filter difficulty in installation and layout, is applicable to colliery thin coal bed fully-mechanized mining face electric-controlled hydraulic support more.
Utility model content
This utility model purpose is to provide a kind of high precision high flow rate filter, and maintenance convenience is good.
For reaching above-mentioned purpose, the solution that this utility model is taked is: a kind of high precision high flow rate filter, including: valve body, element kit, valve body has valve pocket, valve pocket port is provided with interior plug-in mounting face, and element kit is inserted in valve pocket, element kit and interior plug-in mounting face seal.
This utility model compared with prior art, has the advantages that the whole element kit of filter uses plug-in, and this structure, in the case of downhole operations space and institute's use instrument are limited, can be greatly enhanced the convenience of maintenance.It is applicable to coal mine fully-mechanized mining working hydraulic support.
Accompanying drawing explanation
Fig. 1 is the structure chart of the present embodiment.
Fig. 2 is the structure chart of element kit.
In figure: 1, element kit, 2, valve body, 3, O RunddichtringO one, 11, swivel nut, 12, O RunddichtringO two, 13, drainage screen, 14, skeleton, 15, end cap, 16, ceramic glue, 21, interior plug-in mounting face.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing thereof, this utility model is described again.
See Fig. 1, a kind of high precision high flow rate filter, including: valve body 2, element kit 1, valve body 2 has valve pocket, valve pocket port is provided with interior plug-in mounting face 21, and element kit 1 is inserted in valve pocket, and element kit 1 seals with interior plug-in mounting face 21.
Seeing Fig. 1, the annular chamber area of passage between described valve body 2 and element kit 1 is five times of valve pocket import drift diameter area, and therefore maximum stream flow can reach 800L/min.And in actual operating mode, the working flow of whole hydraulic system has only to 400L/min, so the flow of this filter is considerably beyond the requirement of system.It is simultaneously applicable to the high accuracy working condition of different flow demand.
Seeing Fig. 2, described element kit 1 is made up of swivel nut 11, drainage screen 13, skeleton 14, end cap 15, and drainage screen 13 uses three layers of rustless steel sintered meshwork, is wrapped in outside skeleton 14, and two ends are bonded with swivel nut 11 and end cap 15 respectively by ceramic glue 16.The wall thickness maximum of skeleton 14 can reach 5mm, and intensity is high, is hardly damaged.Even if when drainage screen 13 Partial Blocking, area of passage reduces, and inside and outside differential pressure increases, and also will not damage filter element.
Seeing Fig. 1, described valve body 2 is embedded with O RunddichtringO 1, the specification of O RunddichtringO 1 is 30mm × 3.1mm.
Seeing Fig. 2, described swivel nut 11 is embedded with O RunddichtringO 2 12, the specification of O RunddichtringO 2 12 is 45mm × 3.1mm.
