Background technology
In prior art, the structure of filter is varied, oil emulsion at hydraulic pressure system of hydraulic support working media used, because colliery conditions down-hole is more severe, unavoidably there is impurity, if these impurity can not be cleared out in time, normally in service in system, these impurity can pollute other Hydraulic Elements, thereby cause the operation of hydraulic system part ineffective, out of control.Be subject to due to subsurface environment, space, in the past conventional filter volume is all larger, take up room large, and unreasonable structure, cost is high.
At present, conventional manual backwashing filter device on underground hydraulic support frame, element kit about entering, liquid return hole is arranged symmetrically with, when emulsion enters from inlet, enter element kit chamber by steel ball, still because the emulsion of a large amount of filtered can be accompanied with a large amount of impurity, cause it to be trapped between sphere and sealing surface, steel ball cannot normally be rotated, increase handle moment, impact is used; Also have because processing handle installing hole and be difficult to control with respect to the mismachining tolerance of anti-row's mouthful side, cause rear steel ball and inlet ball seat tension are installed, center skew, steel ball rotation difficulty.
Summary of the invention
The utility model takes up room greatly in order to solve existing manual backwashing filter device exactly, because unreasonable structure causes the problem of handle viscous operating difficulties, and provides a kind of manual backwashing filter device.
The technical solution adopted in the utility model: a kind of manual backwashing filter device, it comprises Handleset 1, valve body 2, the first spool 3, the second spool 4, joint 5, filter core 6, screw plug 7, in valve body 2, be set side by side with the first spool installation cavity 8 and the second spool installation cavity 9, the first spool installation cavity 8 and the second spool installation cavity 9 are communicated with by inlet opening 10, above the first spool installation cavity 8 and the second spool installation cavity 9 with in inlet opening 10 direction arranged side by side, be provided with the first anti-round 11, the first anti-round 11 and the first spool installation cavity 8 and the other commissure of the second spool installation cavity 9 are logical, the second anti-round 12 other commissure vertical with the first anti-round 11 is logical, the outlet of the second anti-round 12 is anti-row's mouth 13, in valve body 2 with in the centre bore of the first spool installation cavity 8 and the second spool installation cavity 9 direction arranged side by side, be provided with filter core installation cavity 14, filter core installation cavity 14 is two filter chambers, filter core installation cavity 14 is through-hole structure, and wherein the first spool installation cavity 8 and the second spool installation cavity 9 are communicated with filter core installation cavity 14 respectively, described through hole one end is by screw plug 7 shutoff, another port is working hole 15, the first spool 3 and the second spool 4 are inserted into respectively in the first spool installation cavity 8 and the second spool installation cavity 9, joint 5 is arranged on the import of inlet opening 10, Handleset 1 is arranged on the described spool of being positioned at of valve body 2 top, for controlling the feed liquor and anti-row of spool.
Described Handleset 1 is controlled respectively the pressing plate 18 of the first spool 3 and the second spool 4 by handlebar 16, cam 17 and two.
The utility model compared with prior art its beneficial effect is: 1. the lever operated moment of the utility model is little, and contamination resistance is strong, and attended operation is convenient; 2. the utility model volume is little, and compact conformation is reasonable, effectively reduces the trouble point of equipment, and global regular maintenance also greatly reduces the troubleshooting time, the service life of extension device; Spool and filter core adopt plug-in, are convenient to assembling, have improved sealing, have improved production efficiency; 3. operating grip of the present utility model and the filter core side that exists together, can complete maintenance work in the down-hole of narrow space without large space too, very convenient.
