According to the dynamic parameter matching control device for the multiplex reversing valve and the hydraulic oil cylinder, the dynamic matching of the working parameters of the multiplex reversing valve and the hydraulic oil cylinder is achieved by the electromagnetic diversion valve and the PLC.
Description
Technical field
The utility model relates to a kind of selector valve and hydraulic jack parameter Dynamic matching control gear, especially relates to a kind of multiple directional control valve and hydraulic jack parameter Dynamic matching control gear.
Background technique
The tradition selector valve is undertaken by a spool the control of oil inlet and outlet, it is definite that the opening corresponding relation of oil inlet and outlet adds man-hour as far back as spool design, can not revise in using process, thereby the control logic relation between the hydraulic fluid compressing cylinder oil inlet and outlet that makes can not be made amendment according to the utilization operating mode.Therefore, for certain sheet selector valve, the parameter relative fixed of the pairing hydraulic actuator of its work that is to say the corresponding specific hydraulic fluid compressing cylinder of a slice selector valve.
The model utility content
The technical problems to be solved in the utility model is that a kind of multiple directional control valve and hydraulic jack parameter Dynamic matching control gear of realizing parameter Dynamic matching between selector valve and the hydraulic jack is provided.
The technical solution of the utility model is: a kind of multiple directional control valve and hydraulic jack parameter Dynamic matching control gear, comprise hydraulic jack I, hydraulic jack II, the electromagnetic steering valve, multiple directional control valve, PLC programmable controller and contactor, described hydraulic jack I links to each other with multiple directional control valve by solenoid directional control valve with hydraulic jack II, described hydraulic jack I links to each other with solenoid directional control valve respectively with hydraulic jack II, described solenoid directional control valve links to each other with multiple directional control valve, solenoid directional control valve also links to each other with the PLC programmable controller, and described PLC programmable controller links to each other with multiple directional control valve by contactor; The hydraulic oil inlet of described multiple directional control valve links to each other with hydraulic oil container by hydraulic-pressure pump, and the hydraulic oil return opening of multiple directional control valve links to each other with hydraulic oil container by one-way valve.
Described hydraulic fluid compressing cylinder I, hydraulic fluid compressing cylinder II have different structures and performance parameter.
The dependency structure of hydraulic fluid compressing cylinder I and hydraulic fluid compressing cylinder II and the control strategy of performance parameter and multiple directional control valve all write the PLC programmable controller in the mode of program, when solenoid directional control valve was connected different hydraulic jacks, the PLC programmable controller can be adjusted the combination relation of multiple directional control valve to adapt to the demand of corresponding hydraulic jack by contactor according to the relevant parameter of hydraulic jack.
This different parameters Dynamic matching that realizes the hydraulic jack of multiple directional control valve 4 and different structure by solenoid directional control valve 3 and PLC programmable controller 5, solve the difficult problem that to make amendment based on the relation of the control logic between the multiple directional control valve 4 different operating hydraulic fluid ports of twin-core valve, expanded the application area of multiple directional control valve.
Description of drawings
Fig. 1 is the utility model example structure schematic block diagram.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
With reference to Fig. 1, present embodiment comprises hydraulic jack I1, hydraulic jack II2, electromagnetic steering valve 3, multiple directional control valve 4, PLC programmable controller 5 and contactor 6, described hydraulic jack I1 links to each other with multiple directional control valve 4 by solenoid directional control valve 3 with hydraulic jack II2, described hydraulic jack I1 links to each other with solenoid directional control valve 3 respectively with hydraulic jack II2, described solenoid directional control valve 3 links to each other with multiple directional control valve 4, solenoid directional control valve 3 also links to each other with PLC programmable controller 5, and described PLC programmable controller 5 links to each other with multiple directional control valve 4 by contactor 6; The hydraulic oil inlet of described multiple directional control valve 4 links to each other with hydraulic oil container 9 by hydraulic-pressure pump 7, and the hydraulic oil return opening of multiple directional control valve 4 links to each other with hydraulic oil container 9 by one-way valve 8.
Hydraulic jack I1, hydraulic jack II2 have different structures and performance parameter.
The control strategy of the dependency structure of hydraulic jack I1 and hydraulic jack II2 and performance parameter and multiple directional control valve 4 all writes PLC programmable controller 5 in the mode of program.
Working principle: when solenoid directional control valve 3 is connected hydraulic jack I1, PLC programmable controller 5 can be adjusted the combination relation of multiple directional control valve 4 according to the relevant parameter of hydraulic jack I1 by contactor 6, to adapt to the corresponding demand of hydraulic jack I1, and then, under the effect of the hydraulic-pressure pump 7 that links to each other with hydraulic oil container 9, give hydraulic jack I1 and hydraulic jack II2 fuel feeding; Otherwise, when under the effect of solenoid directional control valve 3, when hydraulic jack II2 started working, PLC programmable controller 5 can pass through the combination relation that contactor 6 is adjusted multiple directional control valves 4 according to the relevant parameter of hydraulic jack II2, to adapt to the demand of corresponding hydraulic jack II2.
This different parameters Dynamic matching that realizes the hydraulic jack of multiple directional control valve 4 and different structure by solenoid directional control valve 3 and PLC programmable controller 5, solve the difficult problem that to make amendment based on the relation of the control logic between the multiple directional control valve 4 different operating hydraulic fluid ports of twin-core valve, expanded the application area of multiple directional control valve.
