Description
Technical field
The utility model relates to a kind of electromagnet, specifically is a kind of being installed on the ratio valve body, is used for the distance of the valve core movement in the control ratio valve body, thereby can realize the ratio valve control electromagnet of the parameter proportional control such as pressure, flow of hydraulic system.
Background technology
We know, after hydraulic system installs, before not feeding hydraulic oil; Space in the pipeline of hydraulic system and the valve body by air in occupation of; In the process that feeds hydraulic oil first, need the air in pipeline and the valve body be ejected fully, the perisporium that is installed in the bonnet of the electromagnet on the proportioning valve usually is provided with a plurality of screwed holes that are used for air in discharge line and the ratio valve body; The exhaust bolt of all having screwed on each screwed hole; During exhaust, through unscrewing any one exhaust bolt, the air in ratio valve body and the pipeline can eject from the gap of exhaust bolt and screwed hole.Though common ratio valve control electromagnet all has the function of this exhaust; But all be to rely on the fit clearance between interior each parts of electromagnet that air is passed through usually between screwed hole and the ratio valve body; Because the sectional area of the fit clearance between each parts is all smaller usually; This just causes the air in pipeline and the ratio valve body to discharge the time that needs than long fully, if the air in pipeline and the ratio valve body can not be discharged the instability in the time of will causing hydraulic work system fully.
The utility model content
The technical problem that the utility model will solve is, provides a kind of and feeds first in the process of hydraulic oil in hydraulic system, can be comparatively fast the clean ratio valve control electromagnet of the discharging of the air in pipeline and the ratio valve body.
The technical solution of the utility model is that a kind of ratio valve control electromagnet with following structure is provided: comprise shell, power connection, coil block, bonnet, buting iron, guide pin bushing, push rod and supporting base, coil block connects in the enclosure; Power connection is connected with shell, and bonnet is connected the right-hand member of shell, and buting iron is connected the left end of shell; Guide pin bushing is through being connected with buting iron at a distance from the magnetic copper ring, and buting iron, separated magnetic copper ring and guide pin bushing all are inserted in the inner chamber of coil block, are connected with iron core on the push rod; Iron core is inserted in the guide pin bushing and can in guide pin bushing, endwisely slips, and iron core is provided with axial first spill port, and supporting base is inserted in the right-hand member of guide pin bushing; Supporting base is provided with axial second spill port, and the push rod right-hand member is inserted in the fairlead in the supporting base, and the push rod left end is inserted in the linear bearing in the buting iron; The perisporium of bonnet is provided with a plurality of screwed holes that communicate with the inner chamber of bonnet, is rotary with exhaust bolt on the screwed hole, wherein; Push rod is provided with the axial exhaust through hole, and the axial exhaust through hole communicates with the inner chamber of bonnet.
After adopting above structure; Compared with prior art; The utility model ratio valve control electromagnet has the following advantages: with to rely in the electromagnet fit clearance between each parts that air is passed through between the screwed hole of prior art and the ratio valve body different; Because the push rod of the utility model ratio valve control electromagnet is provided with the axial exhaust through hole, the axial exhaust through hole communicates with the inner chamber of bonnet, behind the exhaust bolt that unscrews on the bonnet; Air in pipeline and the ratio valve body can not select the less fit clearance of sectional area between interior each parts of electromagnet to pass through; But can eject fast through the bigger exhaust hole of sectional area, therefore, the utility model ratio valve control electromagnet can be comparatively fast clean the discharging of the air in pipeline and the ratio valve body.
