Abstract
A filter consists of a valve shell, a filtering element component, a joint and a U-shaped clamp, wherein a liquid inlet P is arranged at the upper left side of the valve shell; a valve cavity for installing the filtering element component and the joint is arranged on the left side of the valve shell; a liquid outlet A is arranged on the joint; the liquid inlet P is communicated with the valve cavity; and the filtering element component is formed in a way that two ends of a filter screen formed by a coarse filter screen and a fine filter screen are connected with a turning liquid plug and a core shaft by welding, and is wholly inserted into the valve cavity. The filter is used by a hydraulic support of a full-mechanized mining face of a mine.
Description
Technical field
The utility model relates to a kind of filter, refers in particular to a kind of filter that is used for coal mine fully-mechanized mining working hydraulic support feed liquor oil circuit.
Background technology
In the prior art, structure of filter is varied, at the used working media of hydraulic support hydraulic system is oil emulsion, because the colliery conditions down-hole is more abominable, unavoidably has impurity, if these impurity in time can not be removed away, normally in service in system, these impurity can pollute other Hydraulic Elements, thereby cause the operation of hydraulic system part ineffective, out of control, even damage.Be subjected to due to subsurface environment, the space, after the plugged filter commonly used in the past, manually backwash or shutdown are cleaned, and can't determine when stop up, and the operating space requires bigger, has had a strong impact on Coal Production and safety.
The utility model content
The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and a kind of filter that is used for the coal mine fully-mechanized mining working hydraulic support is provided.
For achieving the above object, the solution that the utility model is taked is: a kind of filter, it comprises valve casing, element kit, joint, U-shaped card, the valve casing upper left side is provided with the P inlet, the valve casing left side is provided with the valve pocket that element kit and joint are installed, and joint is provided with the A liquid outlet, and P inlet and valve pocket communicate, form element kit by the filter screen two ends that coarse strainer and fie screen constitute by stifled the linking together of welding and commentaries on classics liquid, the whole valve pocket that inserts of element kit with mandrel.
Its operation principle is: when P inlet feed liquor, liquid filters from the outside filter core inside that flows into of filter core through commentaries on classics liquid is stifled, and the liquid after the filtration flows into hydraulic control component through the A liquid outlet, makes control element energy operate as normal.
Description of drawings
Fig. 1 is that the master of present embodiment looks portion's face structural representation.
Among the figure: 1, valve casing, 2, to change liquid stifled, 3, the fine filtering core, 4, coarse filter element, 5, valve pocket, 6, mandrel, 7, joint, 8, the U-shaped card, 9, the A liquid outlet, 10, the P inlet.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Referring to Fig. 1, a kind of filter, it comprises valve casing 1, element kit, joint 7, U-shaped card 8, the valve casing upper left side is provided with P inlet 10, valve casing 1 left side is provided with the valve pocket 5 that element kit and joint 7 are installed, and joint 7 is provided with A liquid outlet 9, and P inlet 10 and valve pocket 5 communicate, the filter screen two ends that constitute by coarse strainer 4 and fie screen 3 by welding with change liquid stifled 2 and mandrel 6 and link together and form element kit, the whole valve pocket 5 that inserts of element kit.
