Abstract
The utility model discloses a hydraulic large-flow high-speed digital valve. The hydraulic large-flow high-speed digital valve comprises a valve body and a valve core installed inside the valve body in a sliding mode. a sealing surface is arranged at one end of the valve core and matched with a sealing surface inside the valve body for forming a sealing interface. An oil inlet channel and an oil outlet are formed in the two sides of the sealing interface respectively. The oil inlet channel is located between the valve body and the valve core and surrounds the valve core, and therefore the action resultant force on the valve core from hydraulic oil feed under the closing state of the digital valve is zero. The oil outlet is arranged at one end of the valve body. A moving armature is arranged at the other end of the valve core. A static armature is arranged the other end of the valve body. The static armature, an electromagnetic coil and the moving armature form an electromagnet. The direction of electromagnetic pull force exerted on the moving armature is the same as the sliding direction of the valve core. A pressure balance cavity is formed between the valve body and the moving armature. The valve body is provided with a fluid channel, and the fluid channel is communicated with the oil outlet and the pressure balance cavity. A reset spring is arranged between the valve body and the moving armature. The stressed direction of the reset spring and the moving direction of the valve core are the same. The hydraulic large-flow high-speed digital valve can eliminate hydraulic unbalanced force.
Description
Technical field
The utility model relates to the Solenoid Valve Technology field, especially relates to a kind of large flow digital valves of high-speed response of Hydraulic Field.
Background technique
Along with improving constantly of Hydraulic Field automatization level, day by day urgent 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 large, and namely flow is very little.Typical products working pressure 20MPa, flow is 2～9 liters/min only, frequency response 5ms.Obviously, apart from the engineering hydraulic system flow, reach a few hectolitre per minute, even higher requires gap very far away.
The model utility content
Technical problem to be solved in the utility model is: a kind of large 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, the technical solution of the utility model is: the large flow high-speed figure of hydraulic pressure valve, comprise valve body and be slidably mounted on the interior spool of described valve body, one end of described spool is provided with sealing surface and with sealing surface in described valve body, matches and forms 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 in off position the hydraulic pressure oil-feed to make a concerted effort to the effect of described spool is zero, 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 with described moving armature, forms electromagnet, 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 moving armature, described spool is provided with 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 moving armature, described Returnning spring is subjected to force direction consistent with described valve core movement direction.
Adopted technique scheme, the beneficial effects of the utility model are: in the digital valve opening state, the oil outlet hydraulic fluid pressure is delivered to pressure balance chamber by 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 subject to the restriction of hydraulic pressure, can realize large flow digital valves, and under the effect of electromagnetic force and spring force, realizes response fast.
