Background technique:
Series of advantages such as at present, hydraulic cartridge valve has simple in structure, and flow resistance is little, impacts for a short time, and through-current capability is big, and action is fast, and amount of leakage is few are widely used in industries such as lathe, casting forging, metallurgy, boats and ships, mine.But existing cartridge valve mostly is to adopt internal control, can be subjected to the influence of system pressure in the commutation process, and it is unreliable to close, and the opening and closing speed of response is slow, can not satisfy the demand of modern rapid forge; In addition, the switching process of existing cartridge valve is not arbitrarily controlled.
Summary of the invention:
The purpose of this utility model, provide the complete active throttling cartridge valve of a kind of proportion pilot servocontrol, it be adopt external control oil passing ratio guide servovalve with two-way pilot pressure realize controlling spool fast, switch steadily and reliably, the opening and closing process is not influenced by the dynamic property of the through-flow fluid of master; And main valve plug has displacement transducer, and the switch valve element position process of cartridge valve is arbitrarily controllable, overcomes the many not enough problem that exists in the prior art.
The complete active throttling cartridge valve of the utility model proportion pilot servocontrol takes following technological scheme to realize: it is to be made of valve pocket and ladder-type hollow spool and proportion pilot servovalve and displacement transducer, device ladder-type hollow spool in the axial bore of valve pocket, control cover plate is nested with on ladder-type hollow spool and valve pocket larger diameter end, the connection base is equipped with in ladder-type hollow spool upper end, connect and connect the Displacement Feedback bar above the base, connect valve gap above the control cover plate, the control cover plate side is provided with the proportion pilot servovalve, installs displacement transducer above the valve gap; The valve pocket smaller diameter end be provided with four to six radially hydraulic fluid port be connected with spool, seal ring is installed at the big small end of valve pocket place respectively, ladder-type hollow spool upper, middle and lower is equipped with seal ring respectively with valve pocket and cover plate contact segment respectively; The valve pocket larger diameter end on the cover board is provided with the logical proportion pilot servovalve of oil circuit, and ladder-type hollow spool upper end portion on the cover board is provided with the logical proportion pilot servovalve of oil circuit.
The effect of the complete active throttling cartridge valve of the utility model proportion pilot servocontrol is simple in structure, quick opening and closing spool, spool is realized steadily and accurately reliably playback, adopt two-way pilot pressure to realize the opening and closing of valve fast, the opening and closing process is not subjected to main through-flow oil liquid pressure and flow effect, pilot valve both can adopt the proportion pilot servovalve, available again regular tap valve control, and control accuracy and reliability height are widely used on the hydraulic cartridge valve of industries such as lathe, casting forging, metallurgy, boats and ships, mine.
Description of drawings:
The complete active throttling cartridge valve of the utility model proportion pilot servocontrol will describe in further detail in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the complete active throttling cartridge valve of the utility model proportion pilot servocontrol.
