Description
Technical field
The invention belongs to overflow valve technical field, specifically a kind of overflow valve calibrated automatically.
Background technology
Overflow valve is a kind of hydraulic pressure control valve, mainly plays level pressure overflow, voltage stabilizing in hydraulic test, and system is unloaded
Lotus and safeguard protection effect.
When system pressure is more than specified value, the pressure of high pressure oil overcomes spring force in overflow valve, partial high pressure
Oil spilling road of the oil through overflow valve returns to fuel tank.When oil pressure is in safe range, spring will block up under the action of itself pretightning force
Head is pressed on valve position, and overflow valve is closed.
The elastic force of spring can be gradually reduced in overflow valve during long-term use, if the spring force mistake of overflow valve
Small or spring shortens failure, and hydraulic oil can force plug to leave valve bit stream to enter oil spilling road under less than system authorized pressure,
Interior leakage is caused, thrashing is made.Spring must be replaced when repairing, and adjusting screw is then utilized to adjust spring pressure to defined pressure
Power.Overflow reversal valve service life using this kind of structure is short, and it is troublesome in poeration to replace spring.
Invention content
The present invention is in view of the shortcomings of the prior art, provide a kind of overflow valve calibrated automatically, this kind of overflow valve is in spring force
Be capable of the elastic force of automatic adjuster spring after reduction so that the elastic force that the spring provides always within the limits prescribed, to extend
The service life of overflow reversal valve, and it is easily achieved the automation control of valve.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：It is a kind of calibrate automatically overflow
Valve, including overflow valve body are flowed, the overflow valve body includes runner, plug and spring base, and the spring base is blocked up with described
It is provided with spring between head, the runner side is provided with several limit raised lines, and the spring base side is provided with elastic rod, institute
It states and is provided with iron block on spring base, the electromagnet coordinated with the iron block, the spring base are provided on the overflow valve body
The elastic force for slipping over the limit raised line is equal to the spring to the upper limit of the elastic force prescribed limit of plug, the spring base with it is adjacent
The two limit raised lines upper limit that the elastic force difference of the spring is less than the spring to the elastic force prescribed limit of plug when abutting against
With the difference of lower limit.This kind of overflow valve is powered by electromagnet and iron block is attracted to make spring base towards compression when needing to adjust
The direction of spring is moved, and elastic rod bending slips over limit raised line, and spring is compressed, and after electromagnet power-off, spring base is by spring
Elastic force be pushed back into automatically on one of limit raised line, since the spring base and the adjacent two limit raised line abut against when institute
The difference that the elastic force difference of spring is less than the spring to the upper limit and lower limit of the elastic force prescribed limit of plug is stated, therefore, at this time
Spring is to the elastic force of plug always in prescribed limit.Therefore it can also make spring to stifled by compression after spring shortens failure
The pressure of head so that the service life of overflow valve is elongated, and is easily achieved the automation control of valve in prescribed limit.
In above-mentioned technical proposal, it is preferred that the electromagnet include around the conductive coil for being located at the overflow valve body with
And the overflow valve body between the conductive coil.Make the structure of overflow valve body compacter using the structure.
In above-mentioned technical proposal, it is preferred that be provided with radial slideway in the overflow valve body, set in the radial direction slideway
It is equipped with sliding block, the limit raised line is set on the sliding block, and the slider top is provided through the guiding of overflow valve chest
Bar, the guiding boom end are fixed on adjustable plate, are rotated on the adjustable plate and are provided with adjusting nut, the overflow valve chest
On be provided with the adjusting screw hole coordinated with the adjusting nut.Sliding block liter can be made by adjusting adjusting nut using the structure
Drop, so that limit raised line lifting, the deformation quantity that spring base will slip over limit raised line elastic rod changes, to realize spring pair
The elastic force of plug is adjusted.
In above-mentioned technical proposal, it is preferred that be provided with sealing ring between the radial direction slideway and the sliding block.Using the knot
Structure increases the leakproofness between sliding block and radial slideway, prevents hydraulic fluid leak.
Compared with prior art, the present invention having the advantages that：This kind of overflow valve passes through electromagnetism when needing to adjust
Tie Tong electric attraction iron block makes spring base be moved towards the direction of compressed spring, and elastic rod bending slips over limit raised line, spring quilt
Compression, after electromagnet power-off, spring base is pushed back by the elastic force of spring on one of limit raised line automatically, due to the bullet
The spring abutment elastic force regulation that the elastic force difference of the spring is less than the spring to plug when being abutted against with the adjacent two limit raised line
The upper limit of range and the difference of lower limit, at this time spring to the elastic force of plug always in prescribed limit.Therefore shorten in spring and lose
It can also make spring to the pressure of plug in prescribed limit by compression after effect, so that the service life of overflow valve becomes
It is long, and it is easily achieved the automation control of valve.
Description of the drawings
Fig. 1 is the schematic cross-sectional view of the embodiment of the present invention.
Specific implementation mode
