Description
Technical field：
The present invention relates to technical field of metallurgical machinery, specifically a kind of hydraulic cartridge valve core withdrawing device；Can extensive use
Hydraulic cartridge valve core is dismantled in hydraulic system in metallurgical machinery.
Background technology：
PQF Hot Lines reversal valve is typically using the reversal valve of German BOSCH-REXROTH company.Wherein many positions LC type inserted valves.Should
Class valve allows maximum stream flow big（Maximum stream flow is up to 25000L/min）, stable and reliable in work, action is accurate, automaticity
High, service life is long, effectively meets device action demand, the hydraulic control component as relatively broad application.LC types electricity
The pilot valve of liquid reversal valve is generally adopted by 4WE types electromagnetism Direct Action Type direction valve plus LFA types control cover plate composition.Pass through guide
The switching of valve core of main valve is realized in the action switching of valve element, so as to realize the commutation action of oil cylinder.In actual applications due to valve element
Abrasion or spring fatigue, valve element jam or the phenomenon that can not be rebounded can be caused.Such valve is mainly used in moment big flow area
Anticollision quick relief is played a part of at many positions in domain, if valve element jam will certainly cause the rigid shock of mechanical structure, needs
To change in time.Although valve block and valve element manufacture accurate, due to installing and using reasons such as abrasions, valve element in valve opening
Tilt, radial imbalance force and torque are all than larger, along with valve element is submerged inside valve block, it is difficult to from outside by valve core taking,
In the presence of situation is dismantled repeatedly, waste time and energy, change a valve element and generally require more than 2 hours, efficiency is low.
The content of the invention：
The present invention seeks to overcome the shortcomings of above-mentioned prior art, and provide a kind of hydraulic cartridge valve core withdrawing device；Main solution
The problem of certainly existing valve element jam takes out difficulty inside valve opening.
The technical scheme is that：A kind of hydraulic cartridge valve core withdrawing device, including bearing, it is characterized in that,
Described bearing is connected with tensioner pull bar one end, and cap, the other end threaded connection adjustment of tensioner pull bar are drawn in socket on tensioner pull bar
Nut adds handle；Three levers of installation are hinged by bearing pin even circumferential on described bearing, lever left end is respectively cut with scissors by bearing pin
One screw die of installation is connect, screw die outer wall carries circumferential thread, and lever right-hand member is respectively hinged a connecting rod by bearing pin, and connecting rod passes through pin
Axle is articulated with drawing cap；There is 1 jump ring on all bearing pins.
Compared with the prior art a kind of hydraulic cartridge valve core withdrawing device of the present invention has prominent substance special
Point and marked improvement, 1, be a kind of extracting tool, be conveniently replaceable inserting valve element, prevent itself because valve element jam inside valve opening not
It is good to take out；2nd, it is simple in construction, easy to use, the time for changing inserting valve element can be greatly reduced, maintenance personal is reduced, work is improved
In safety coefficient；With universal promotional value.
Brief description of the drawings：
Fig. 1 is the structural representation of the present invention；
Fig. 2 is that withdrawing device of the present invention takes valve element schematic diagram；
Fig. 3 is the design sketch of the present invention.
Wherein：1 screw die, 2 bearings, 3 connecting rods, 4 tensioner screw mandrels, 5 drawing caps, 6 adjusting nuts add handle, 7 levers, 8 jump rings, 9
Insert valve element, 10 valve bodies.
Embodiment：
For a better understanding and implementation, providing specific embodiment below in conjunction with the accompanying drawings, the present invention is described in detail；Illustrated embodiment
It is only used for explaining the present invention, is not intended to limit the scope of the present invention.
Embodiment 1, referring to Fig. 1, according to design needs, is processed into bearing 2, bearing 2 is passed through with the one end of tensioner pull bar 4
Hinge, cap 5 is drawn in socket on tensioner pull bar 4, and adjusting nut plus handle are connected through a screw thread in the other end of tensioner pull bar 4
6, adjusting nut adds the internal thread of handle 6 to be matched with the external screw thread of tensioner pull bar 4, and adjusting nut adds handle 6 on tensioner pull bar 4
It is movable by screw thread；Three levers 7 of installation are uniformly hinged by bearing pin on the circumference of bearing 2, the left end of lever 7 passes through pin
Axle is respectively hinged one screw die 1 of installation, and the outer wall of screw die 1 carries circumferential thread, and the right-hand member of lever 7 is respectively hinged a connecting rod 3 by bearing pin,
Connecting rod 3, in having 1 jump ring 8 on drawing cap 5, all bearing pins, is prevented bearing pin from departing from, forms one kind of the present invention by hinge
Hydraulic cartridge valve core withdrawing device.
A kind of hydraulic cartridge valve core withdrawing device of the present invention, selects the screw die 1 of suitable bore, screw die 1 is filled in when using
Enter to insert in valve element 9, turn adjusting nut adds handle 6, promote it and draw cap 5 to move inward, draw cap 5 to be pulled by connecting rod 3
Lever 7 is moved inward, and is displaced outwardly screw die 1 using lever principle, the inserting inwall of valve element 9 is pushed down, because the outer wall of screw die 1 is carried
Circumferential thread, will combine closely under pressure or so in inserted valve inwall, recycle manpower to hold with a firm grip adjusting nut plus handle 6, to
An outer drawing can easily take out the inserting valve element 9 of valve body 10.
