Description
Technical field
The present invention relates to Solenoid Valve Technology fields, more particularly to a kind of good hydraulic buttery valve of stability.
Background technique
Coil and spring with control valve core movement in hydraulic buttery valve, coil and spring are separately positioned on the two of spool
End.The opening and closing of hydraulic buttery valve upper valve core is powered the sum of active force of electromagnetic force and spring generated by coil to determine.Its
In, the active force of spring is usually fixation, controls the movement of hydraulic valve core by controlling the size of electromagnetic force.But
Be spring in use, there are a large amount of negative effect factors；Such as sluggish deviation, shrinkage, batch etc., spring
The strong difference in size of meeting, spring will appear certain spring force failure after high temperature between batch and batch, these all can
The unstable of spring force is caused, so that deviation occurs in the performance curve that will cause hydraulic buttery valve, stability is poor.
Summary of the invention
The invention mainly solves the technical problem of providing a kind of good hydraulic buttery valves of stability, can pass through the second line
Circle replaces original spring structure, to guarantee the stability of hydraulic buttery valve.
In order to solve the above technical problems, one technical scheme adopted by the invention is that: provide a kind of stability good hydraulic
Solenoid valve, including hydraulic part and the Electrical heads being fixedly linked with the hydraulic part；The hydraulic part includes valve body and sets
It sets in the intracorporal spool of the valve, the spool can move in the valve body along own axes direction；The Electrical heads are fixed
The rear end of the hydraulic part is set；There is the mandril that can push the spool, and described in control on the Electrical heads
The mobile first coil of mandril axis direction；The mandril movement can make the spool mobile to the preceding extreme direction of the valve body；
Front end fixing sleeve on the valve body far from the Electrical heads is equipped with the second coil, the thrust that the second coil energization generates
The spool can be made mobile to the rear extreme direction of the valve body.
Preferably, the open groove for accommodating second coil is provided on the valve body.
Preferably, the power supply source of second coil and the power supply source of the first coil are mutually indepedent.
The beneficial effects of the present invention are: the present invention can replace original spring structure by the second coil, to guarantee
The stability of hydraulic buttery valve；Its structure is simple, easy for operation.
Detailed description of the invention
Fig. 1 is a kind of schematic cross-sectional view for one preferred embodiment of hydraulic buttery valve that stability is good of the present invention.
The components in the drawings are labeled as follows: 1, hydraulic part；11, valve body；12, spool；2, Electrical heads；21, mandril；
22, first coil；3, the second coil.
Specific embodiment
The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawing, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
Referring to Fig. 1, the embodiment of the present invention includes:
A kind of hydraulic buttery valve that stability is good, comprising: hydraulic part 1 and the electricity being fixedly linked with the hydraulic part 1
Magnetic head 2.The hydraulic part 1 includes valve body 11 and is arranged in the intracorporal spool 12 of the valve, and the spool 12 can be in the valve
It is moved in body 11 along own axes direction.The Electrical heads 2 are fixed at the rear end of the hydraulic part 1；The Electrical heads 2
It is upper that there is the mandril 21 that can push the spool 12, and the first coil 22 that control 21 axis direction of mandril is mobile；
The mandril 21 can make the spool 12 mobile to the preceding extreme direction of the valve body 11.Far from the electromagnetism on the valve body 11
First 2 front end fixing sleeve is equipped with the second coil 3, and the thrust that the energization of the second coil 3 generates can make the spool 12 to institute
The rear extreme direction for stating valve body 11 is mobile.The open groove for accommodating second coil 3 is provided on the valve body 11, it can not
Change original volume size, while can be in order to the installation of the second coil 3.The power supply source of second coil 3 and described the
The power supply source of one coil 22 is mutually indepedent, and control first coil 22 that can be more convenient and the second coil 3 simplify a confession
Circuit structure when power supply.
When operating with, by that spool 12 can be made to valve body 11 to the energization of first coil 22,3 no power of the second coil
Front end it is mobile；By that spool 12 can be made to move to the rear end of valve body 11 to 22 no power of first coil, the energization of the second coil 3
It is dynamic；It is powered to first coil 22 and the second coil 3, generates the electromagnetic force of the generation of first coil 22, the second coil 3
It is mutually balanced between hydraulic coupling in electromagnetic force and hydraulic buttery valve, just spool 12 can be made to remain stationary；To first coil 22
The electromagnetic force that the electric current for being powered with the second coil 3, but increasing first coil 22 generates first coil 22 is greater than second
The electromagnetic force that coil 3 generates just can make spool 12 smoothly mobile to the front end of valve body 11；To first coil 22 and the second line
Circle 3 is powered, but the electromagnetic force that the second coil of electric current ambassador 3 for increasing the second coil 3 generates is produced greater than first coil 22
Raw electromagnetic force just can make spool 12 smoothly mobile to the rear end of valve body 11.
Second coil 3, which is powered, generates electromagnetic force, spool 12 can be shifted to initial position onto, the starting point of such spool 12 can
To define well.It, can be in each position, the electromagnetic force generated by the energization of the second coil 3, liquid stream on function curve
The influence of power and sluggishness is reduced to minimum.
The present invention can replace original spring structure by the second coil 3, to guarantee the stability of hydraulic buttery valve；
Its structure is simple, easy for operation.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is included within the scope of the present invention.
