One end of the valve core is provided with a sealing surface, the sealing surface is matched with a sealing surface inside the valve body, and the two sealing surfaces form a sealing interface. An oil inlet passage and an oil outlet port are arranged on two sides of the sealing interface respectively, the oil inlet passage is located between the valve body and the valve core and surrounds the valve core, the hydraulic oil has no action on the valve core when the digital valve is closed, and the oil outlet port is located at the other end of the valve body. A moving armature is arranged at the other end of the valve core, a static armature and an electromagnetic coil are arranged at the other end of the valve body, the static armature, the electromagnetic coil and the moving armature form an electromagnet, and the moving armature is pulled by the electromagnet in the direction the same with the sliding direction of the valve core. A pressure balance cavity is arranged between the valve body and the moving armature, a fluid passage is arranged on the valve core, and the fluid passage is communicated with the oil outlet port and the pressure balance cavity. A reset spring is arranged between the valve body and the moving armature, the stress direction of the reset spring is the same as the moving direction of the valve core. By means of the hydraulic high-flow and high-speed digital valve, the hydraulic imbalanced force is removed.
Description
Technical field
The present invention relates to the solenoid valve technical field, especially relate to a kind of big traffic figure valve of high-speed response of Hydraulic Field.
Background technique
Along with improving constantly of Hydraulic Field automatization level, urgent day by day for the demand of high-speed figure valve.As everyone knows, the hydraulic pressure unbalanced force increases with the increase of spool size, and can have a strong impact on the motion of spool.Therefore the valve core diameter of current high-speed figure valve can not be too big, and namely flow is very little.Typical products working pressure 20MPa, flow is 2～9 liters/min only, frequency response 5ms.Obviously, reach several hectolitres of per minute apart from the engineering hydraulic system flow, even higher require gap very far away.
Summary of the invention
Technical problem to be solved by this invention is: a kind of big flow high-speed figure of the hydraulic pressure valve that can eliminate the hydraulic pressure unbalanced force is provided.
For solving the problems of the technologies described above, technological scheme of the present invention is: the big flow high-speed figure of hydraulic pressure valve, comprise valve body and be slidingly mounted on the interior spool of described valve body, one end of described spool is provided with sealing surface and matches with sealing surface in the described valve body and forms the seal interface, the both sides of described seal interface are respectively arranged with oil inlet passage and oil outlet, described oil inlet passage is between described valve body and spool and around spool, making described digital valve descend the hydraulic pressure oil-feed that the effect of described spool is made a concerted effort in off position is zero, and described oil outlet is positioned at an end of described valve body;
The other end of described spool is provided with moving armature, and the other end of described valve body is provided with static gag bit and electromagnetic coil and forms electromagnet with described moving armature, and the suffered electromagnet pull of described moving armature is consistent with the spool glide direction; Be provided with pressure balance chamber between described valve body and the moving armature, described spool is provided with the fluid passage, and described fluid passage is communicated with described oil outlet and pressure balance chamber; Be provided with Returnning spring between described valve body and the moving armature, described Returnning spring is subjected to force direction consistent with described valve core movement direction.
Adopted technique scheme, beneficial effect of the present invention is: in the digital valve opening state, the oil outlet hydraulic fluid pressure is delivered to pressure balance chamber by the fluid passage, and it is zero that the suffered axial force of spool is made a concerted effort.The valve closed condition, the hydraulic pressure oil-feed makes a concerted effort to be always zero to the effect of spool.Therefore, the design of spool size no longer is subjected to the restriction of hydraulic pressure, can realize big traffic figure valve, and under the effect of electromagnetic force and spring force, realizes response fast.

Embodiment
The present invention is further described below in conjunction with drawings and Examples.
Embodiment one:
As shown in Figure 1, the big flow high-speed figure of hydraulic pressure valve, comprise valve body 1 and the spool 2 that is slidingly mounted in the valve body 1, one end of spool 2 is provided with sealing surface and matches with sealing surface in the valve body 1 and forms seal interface 11, the both sides of seal interface 11 arrange oil inlet passage 3 and oil outlet 4 respectively, oil inlet passage 3 is between valve body 1 and spool 2 and around spool 2, and it is zero that the hydraulic pressure oil-feed is made a concerted effort to the effect of spool 2, and oil outlet 4 is positioned at an end of valve body 1.
The other end of spool 2 is provided with moving armature 5, and the other end of valve body 1 is provided with static gag bit 6 and electromagnetic coil 7 and forms electromagnet with moving armature 5, and moving armature 5 suffered electromagnet pulls are consistent with spool 2 glide directions; Be provided with pressure balance chamber 8 between valve body 1 and the moving armature 5, spool 2 is provided with fluid passage 9, and this fluid passage 9 is communicated with oil outlet 4 and pressure balance chamber 8; Be provided with Returnning spring 10 between valve body 1 and the moving armature 5, Returnning spring 10 is subjected to force direction consistent with spool 2 moving direction.
As shown in Figure 1, the big flow high-speed figure of a kind of normal close type hydraulic pressure valve, oil inlet passage 3 is arranged on the valve body 1, electromagnetic coil 7 when electric spool 2 open, spool 2 is closed during dead electricity.During electromagnetic coil 7 dead electricity, under Returnning spring 10 effects, spool 2 offsets with valve body 1, oil inlet passage 3 and oil outlet 4 blocking-up; When electromagnetic coil 7 when electric, the magnetic force of electromagnetic coil 7 overcomes the elastic force of Returnning spring 10, and spool 2 is opened, and this moment, hydraulic oil entered fluid passage 9 and rapid stuffing pressure counter balance pocket 8 from oil inlet passage 3, flow out from oil outlet 4 simultaneously, 2 stressed making a concerted effort of spool are zero.After electromagnetic coil 7 dead electricity, under the effect of Returnning spring 10 power, spool 2 can quick closedown.
