Background technology
Proportion electro-magnet is the important component part of proportioning valve, proportioning valve is under the effect of proportion electro-magnet, the pressure to hydraulic system, the isoparametric proportional control of flow can be realized, described proportional control is exactly carried out the displacement of control ratio valve core by the current value that controller change proportion electro-magnet Inside coil passes into, thus change the opening amount of proportioning valve valve port, realize proportional control.
Proportion electro-magnet structure is primarily of iron core, guide pin bushing, magnetism-isolating loop, pole shoe, housing, coil, push rod composition, configuration communication helix tubular type control coil between guide pin bushing and housing, shell adopts permeability magnetic material, to form magnetic loop, pole shoe, magnetism-isolating loop and guide pin bushing are all located in the inner chamber of coil block, the right-hand member being arranged in the push rod of pole shoe inner chamber is connected with the iron core of guide pin bushing inner chamber, and housing is connected with power connection, and power connection is electrically connected with coil block.
Concerning the electromagnet in work, under energising or power-off or certain electric current (voltage), iron core can arrive assigned address rapidly and accurately, but in fact owing to there is inductance and iron core quality, or the reason of load, the motion process of iron core is made to become complicated, electromagnetically operated valve adhesive motion process can be divided into two stages: adhesive contact transfer time and adhesive run duration, adhesive contact transfer time obtains voltage from coil to play the process that electric current increases to attract current position exponentially, in this process, iron core not yet moves, the lag time because electricity causes with the inertia of magnetic during this period of time, depend on the structure with electromagnet, material, coil voltage, the size of inductance, after entering the adhesive run duration stage, suction is greater than pretightning force, iron core setting in motion, curent change rule is with regard to more complicated: because working gas gap reduces gradually in iron core motion process, coil inductance is made to increase gradually and produce back-emf, it is together with self-induction of loop electromotive force, the growth of common prevention coil current, cause coil current to increase to a certain degree not only no longer to increase, have reduction trend on the contrary, until iron core closes, working gas gap no longer changes, back-emf is zero, and electric current rises to steady-state current by new exponential curve.Depend on the various resistances suffered by spool during this period of time.For the dispose procedure of electromagnetically operated valve, if ignore the impact of eddy current in magnetic conductor, when after coil signal excision, electric current reduces to zero immediately, and iron core is setting in motion immediately, therefore its release contact transfer time is close to zero, short far beyond adhesive contact transfer time.
Existing proportion electro-magnet active force when certain curtage is constant nonadjustable, when operating mode changes, needs the cost plenty of time to regulate, to make proportion electro-magnet be applicable to corresponding operating mode, again realizes proportional control.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, one adjustable proportion electro-magnet of active force when certain curtage is provided.
Object of the present invention is achieved through the following technical solutions: a kind of proportion electro-magnet, it comprises housing, coil block, pole shoe, magnetism-isolating loop, guide pin bushing, be arranged in the iron core of magnetism-isolating loop and guide pin bushing inner chamber and be arranged in the push rod of pole shoe inner chamber, the right-hand member of push rod is connected with iron core, pole shoe is connected to the left end of housing, guide pin bushing is connected with pole shoe by magnetism-isolating loop, pole shoe, magnetism-isolating loop and guide pin bushing are all located in the inner chamber of coil block, coil block is arranged in housing cavity, housing is connected with power connection, power connection is electrically connected with coil block, the right-hand member of described iron core is fixedly connected with spring base, the right side of housing is provided with the through hole coordinated with spring base, spring base is positioned at the left side of the inside of through hole, the right-hand member of through hole is provided with internal thread, through hole right-hand member is provided with the adjustment screw be connected with through hole by screw thread, spring is provided with between the left end of adjustment screw and spring base, spring one end presses on spring base, the other end of spring presses in adjustment screw.
Described spring base is column type, and spring base and through hole are matched in clearance.
The part that described adjustment screw is positioned at outside is also set with dense block jack panel
The present invention has the following advantages:
The present invention is by setting up spring base, spring and adjustment screw, the pretightning force of spring action on electromagnet core can be changed conveniently by adjustment adjustment screw, thus change the size of electromagnet active force when a certain curtage, achieve proportion electro-magnet active force adjustable when certain curtage, thus make electromagnet go for the operating mode of multiple different active force demand.
Adopt proportional flow or the pressure valve of this proportion electro-magnet, the flow of proportion magnetic valve output or the size of pressure within the scope of certain curtage can be regulated by regulating adjustment screw, electromagnetically operated valve can be made to meet the demand of each operating mode.
The present invention is simple and compact for structure, reasonable in design, convenient adjustment, practical, extend the scope of application of the electronically controlled proportional valve of proportion electro-magnet and employing proportion electro-magnet of the present invention, simplify the structure of electronically controlled proportional valve joint, reduce the manufacturing cost of electronically controlled proportional valve, save regulating time when proportion electro-magnet is applied to different operating mode, be beneficial to and increase work efficiency.
