Description
Technical field
The invention belongs to technical field of hydraulic equipment, specifically discloses a kind of hydraulic regulation valve gear.
Background technology
In hydraulic test, hydraulic valve is commonly used to adjust the pressure in hydraulic device, can be quick by the adjusting of hydraulic valve
Regulatory function is realized exactly, using hydraulic valve, can guarantee that the transmission power of hydraulic system is stablized.
But during using hydraulic valve, hydraulic valve is adjusted manually and action delay easily occurs, action delay can cause
Occur movement range increase in the hydraulic test course of work, do not reach the effect of operation finally.In the prior art, hydraulic valve species
It is more, complicated, cause to be easily damaged in use, and processing cost is higher, and difficulty is caused to user's selection.
In view of the above-mentioned problems, the patent of invention of Publication No. CN104976176B discloses a kind of hydraulic regulation valve gear,
It includes hydraulic valve, and the hydraulic valve has housing, there is a first passage through left and right, first passage tool on housing
There are Zuo Kou and You Kou, there is about one perforative second channel on housing, first passage and second channel are crossed as " ten " word
The cavity of structure, the second channel are lower channels below " ten " word structure, and there is electromagnet in face on a second pass, in electricity
There is the spool that can be slided up and down along second channel below magnet, the first spring for having support spool below spool, second is logical
It is the outlet of lower channel below road；It is the neck neck portion to attenuate among the spool, has one to coordinate second to lead to below spool
Sealing ring below road, have side slit below sealing ring, and there is control electromagnet can control lower channel and first
Whether the perforation of passage, which has the advantages that simple in structure, cost is low.
Scheme disclosed in foregoing invention patent is although simple in structure, cost is low, but in use, it is necessary to people in order to control
Solenoid valve, people's easily delay in appearance action in order to control, causes to go out in operation easily now error.
The content of the invention
The purpose of the present invention is providing a kind of adjusting hydraulic regulation valve gear, to solve easily to go out in hydraulic valve operating process
The problem of existing error.
In order to achieve the above object, base case of the invention is：A kind of hydraulic regulation valve gear, including triple-valve body and
Spool, the triple-valve body are equipped with first passage, second channel and third channel, and the first passage and second channel are same
On straight line, the third channel is vertical with first passage and second channel and connects, the third channel and first passage, the
Two passage connectivity parts are equipped with valve core case, and the valve core case is equipped with spool, and the spool and valve core case are rotatablely connected and sealing connects
Touch, valve core inside offers mutual perforative the 6th "T"-shaped passage, two exits on the same straight line of the 6th passage
Equipped with shape identical the first blade and the second blade, first blade and the second blade interior offer fourth lane respectively
Connected with Five-channel, the fourth lane and with Five-channel with the 6th passage, the 6th passage connects with third channel
Logical, the conduit wall both sides of the connectivity part of the first passage, second channel and third channel are all provided with fluted, first blade
Rotated with the second blade when being contacted with groove, groove by fourth lane and Five-channel sealing, the conduit wall and the first blade,
It is equipped between second blade for the restorable elastic component of blade.
The operation principle of this base case is：Before hydraulic regulation valve gear, first by the of hydraulic pressure valve-regulated devices
One passage and second channel are installed on fluid pressure line, when hydraulic system does not work or works normally, in whole hydraulic device
Pressure is in equilibrium state；First blade and the second blade under elastic component pulling force effect, the first blade and the second blade it is logical
Road is exported is in sealing state between conduit wall, due to being in sealing state between spool and valve core case, so first passage
It cannot enter third channel with the hydraulic oil in second channel；When the pressure imbalance in first passage or second channel, leaf
Piece is acted on be subject to out-of-balance force, can drive valve core rotation；Since blade deflects, the fourth lane on the first blade and
Five-channel on two blades is connected with third channel, and hydraulic oil can enter threeway by fourth lane and Five-channel
Road, so as to reduce the pressure in first passage and second channel；When the pressure balance in first passage and second channel, leaf
Piece restores to the original state under elastic component effect, and the passway of fourth lane and Five-channel is in seal shape under conduit wall effect
State；Blade deflects under the action of out-of-balance force to be played the role of automatically adjusting channel inner pressure.
The beneficial effect of this base case is：Using the hydraulic regulation valve gear of this programme, can be played in pipeline certainly
The dynamic effect for adjusting pressure, can guarantee that the stability of pressure in fluid pressure line, while be avoided that and hydraulic pump is caused when pressure is excessive
Damage, increases the service life of hydraulic pump.
Compared with prior art, this programme opened up on the first blade, the second blade and spool identical fourth lane and
Five-channel and the 6th passage, in time can be discharged hydraulic oil by third channel by the 4th and Five-channel, ensure that
Pressure balance in one passage and second channel；Blade is set on spool, since the forced area of blade is big, two face pressure of blade
When power is uneven, blade can deflect in time, the pressure in passage is adjusted, high sensitivity；By in blade and logical
Elastic component is set between road wall, can prevent blade from deflecting in pressure stability, avoids influencing the steady operation of hydraulic system,
Elastic component can guarantee that and can be resetted in time after blade deflection at the same time.
Further, the third channel is flexibly connected with first passage, second channel, and movable connection method is easy to disassemble,
It can be overhauled in time when spool damages.
Further, the third channel is connected with storage pressure oil case, can recycle what third channel ejected by storing up pressure oil case
Hydraulic oil, easy to recycle hydraulic oil.
Further, the storage pressure tank bottoms are equipped with piston, and second spring is connected between the piston and storage pressure oil case,
When storage pressure tank pressure increase, hydraulic oil will promote piston compression second spring, and the pressure of hydraulic oil in passage is converted
Stored for the elastic force of second spring, when pressure imbalance in first passage and second channel, spring promotes piston motion,
Hydraulic oil is quickly added in the passage of pressure imbalance.
Further, rubber pad is equipped with the groove, the first blade and the second blade lead to that after rubber contact, can increase
Leakproofness of the road wall to fourth lane mouth and Five-channel mouth.
