Abstract
The utility model relates to a bi-directional backwashing filter, which comprises a valve body, filter elements and valve balls. Filter elements and end plugs are respectively arranged in two filter element chambers which are arranged on the left side of the valve body along a horizontal direction; a quick coupling liquid inlet connector is arranged on the right end of the valve body along a symmetric line of the two filter element chambers; a quick coupling liquid outlet connector is arranged on the left end of the valve body along the symmetric line of the two filter element chambers; two symmetrical valve holes are arranged in the upper side and the lower side of the right side of the valve body; a slot hole for connecting the two valve holes with a liquid inlet is arranged between bottom parts of the two valve holes; a valve seat, a valve ball and a sewage disposal connector assembly are arranged in each valve hole; a rotating shaft and a handlebar for operating the valve balls are arranged on corresponding positions of the two valve holes on the rear part of the valve body; and auxiliary holes are respectively arranged in the upper side and the lower side of the left part of the valve body and are used for communicating the two filter element chambers with a liquid outlet. When the bi-directional backwashing filter is in work, the two filter elements can be used for filtering operating fluid simultaneously, and impurities are attached to outer circumferences of the filter elements, so a filter screen is blocked by the impurities in the operating fluid after long-time use, then an operating mechanism of a two-position two-way ball valve is rotated for backwashing at the time, and thus the cleanness of the operating fluid can be kept to meet the requirement.
Description
Technical field
The utility model relates to a kind of filter, refers in particular to a kind of bidirectional backwash filter.
Background technology
Hydraulic machinery flows transferring power through working solution in hydraulic system; The cleannes of working solution have fundamental influence to the service behaviour of hydraulic system; Impurity in the working solution can make the task performance of Hydraulic Elements descend; Even damage, so filter is the Hydraulic Elements that each hydraulic machinery must be used.Filter at present commonly used all is an one-way type, after filter core is stopped up by impurity, must shut down more renew cartridge or filter core taken out and clean, and not only wastes time but also pretty troublesome.
The utility model content
The purpose of the utility model is to provide a kind of bidirectional backwash filter; It can pass through working solution by forward; Make impurity in the working solution attached to the excircle of filter core, can make filter recover normal operating conditions oppositely with rinsing out again attached to the impurity on the filter core excircle.For achieving the above object, the solution that the utility model is taked is: a kind of bidirectional backwash filter, it comprises valve body, filter core and valve ball.Valve body left side along continuous straight runs offers the filter core chamber of two symmetries; The identical filter element of one cover respectively is housed in the two filter core chambers; Every cover filter element is blocked up by a filter core and an end to be formed; Filter core is connected as a single entity with left hand thread with end is stifled, and end is stifled to be fixed in the filter core chamber of valve body with right-handed thread; Offer a snap joint formula feed liquor interface at the right-hand member of valve body along the line of symmetry of two filter core chambers, offer a snap joint formula at the left end of valve body along the line of symmetry of two filter core chambers and go out liquid interface; Both sides offer the valve opening of two symmetries about the valve body right side; Offer a slotted hole between two valve openings bottom with two valve openings and inlet opening connection; Valve seat, valve ball and blowdown adapter assembly are installed in each valve opening; The correspondence position of two valve openings offers the shaft hole perpendicular to the valve opening center line in valve body back, and rotating shaft, axle sleeve, spacing pad and handgrip are installed in this shaft hole, respectively offers a fabrication hole two filter core chambers are communicated with liquid outlet in both sides up and down at the valve body left part.It can forward through working solution, make impurity in the working solution attached to the excircle of filter core, can make filter recover normal operating conditions oppositely with rinsing out again attached to the impurity on the filter core excircle.
