Abstract
The utility model relates to a dynamic interposing valve having stoke limitation, especially an interposing valve apparatus wherein the hydraulic control device needs the core of the interposing valve to be rapidly closed or opened, and the hydraulic dynamics of the stroke of the core is limited. A step shaped valve core and a returning spring are arranged inside the step shaped valve sleeve, a control cover board is sheathed onto the step shaped valve sleeve. The returning spring is arranged between the hollowed position of the step shaped valve core and the control cover board. A flow saving sleeve is arranged at the center of the upper end of the control cover board, and a flow saving rod is arranged at the center of the flow saving sleeve. An electromagnetic guidance valve is connected to one side of the control cover board, a first sealing ring and a second sealing ring are arranged at the position where the step shape valve sleeve is connected to the control cover board, and a ring shaped groove is arranged on the top of the control cover board at the position where the step shaped valve sleeve is connected with the control cover board. The utility model has beneficial effects of simple structure, convenient operation, capability of ensuring the core completely opened or closed, effectively controlling the stroke of the core, safe and reliable operation. And the utility model is widely arranged for dynamically controlling the core of the hydraulic interposing valve.
Description
Technical field:
The utility model relates to a kind of travel limits dynamic cartridge valve, particularly hydraulic control device of having the cartridge valve spool is needed quick closedown or unlatching, the dynamic cartridge valve equipment of restriction spool stroke hydraulic.
Background technique:
At present, cartridge valve of the prior art, obtain widely applying in industries such as forging and pressing, metallurgy, mine, boats and ships, in use, when spool is closed, the pressure of valve control chamber unnecessary spool moment unlatching may occur owing to be subjected to the influence of system pressure when spool is closed, and the uncontrollable phenomenon of spool stroke.
Summary of the invention:
The purpose of this utility model, provide a kind of dynamic cartridge valve of travel limits that has, it is to adopt the pilot pressure that separates separately with cartridge valve to realize the fast and reliable unlatching of spool or close, open or close the influence that is not subjected to main cartridge valve characteristic, and the stroke of spool obtains reliable control, realizes the fast and reliable unlatching of spool or the purpose of closing.
The utility model has the dynamic cartridge valve of travel limits and takes following technological scheme to realize, it is by the ladder-type valve pocket, the ladder-type spool, control cover plate, Returnning spring and throttling rod and pilot solenoid valve constitute, ladder-type spool and Returnning spring are set in the ladder-type valve pocket, control cover plate is nested with on the ladder-type valve pocket, between the hollow position of ladder-type spool and the control cover plate Returnning spring is set, the upper end neutral position of control cover plate is provided with the throttling rod cover, throttling rod is nested with in the middle of the throttling rod cover, one side of control cover plate connects pilot solenoid valve, ladder-type valve pocket and control cover plate joint are provided with first seal ring and second seal ring, and ladder-type valve pocket and control cover plate joint are provided with ring-like groove on control cover plate.
The effect that the utility model has the dynamic cartridge valve of travel limits is simple in structure, and is easy to operate, guarantees that spool opens or closes fully, effectively controls the stroke of spool, safe and reliable to operation, is widely used in the dynamically upward setting of control of spool of hydraulic cartridge valve.
