Logical, it is several function selection keys that input function, which selects area,.
Above-mentioned working principle is illustrated one by one with the course of work now in conjunction with attached drawing:
Executing agency's tool of the present embodiment is there are two actuator port, and when work, one of actuator port connects hydraulic oil
Source oil inlet, another actuator port carry out oil return.
As shown in Figure 1: when N is equal to 1, tool is there are two executing agency, it is assumed that executing agency is first is that hydraulic cylinder, when needing to drive
When hydrodynamic cylinder pressure stretches out, referring to the function one of Fig. 3, solenoid valve Y01 and Y02 is no action, and hydraulic oil liquid is successively through P1, solenoid valve
Y01, actuator port A1 enter to the rodless cavity of hydraulic cylinder, and hydraulic cylinder piston rod is pushed to stretch out, the oil liquid in hydraulic cylinder rod chamber
Successively through A2, solenoid valve Y02 to P2, oil return is realized.Equally, when needing driving hydraulic cylinder to shrink, the high-voltage oil liquid of P2 is through electricity
Magnet valve Y02 enters to the rod chamber of hydraulic cylinder, and the oil liquid in hydraulic cylinder rodless cavity is through solenoid valve Y01 oil return.
As shown in Figure 2: when N is equal to 2, there are three executing agencies for tool, at this point, two actuator ports of the first valve group connect
Executing agency one, other two actuator port connect two oil inlet Ps 3 and P4 of the second valve group, two work of the second valve group
Hydraulic fluid port A3 connect two actuator ports of executing agency two with A4, other two actuator port B3 of the second valve group is connect with B4 to be held
Two actuator ports of row mechanism three.
In conjunction with shown in Fig. 2 and Fig. 3: when needing to be implemented the work of mechanism three, solenoid valve Y01, Y02, Y03 and Y04 are obtained
Electricity, the oil liquid at P1 successively enter to executing agency three through solenoid valve Y01, B1, P3, solenoid valve Y03, B3, drive executing agency
Three work, executing agency three carry out oil return through B4, solenoid valve Y04, P4, B2, solenoid valve Y02 to P2；When needing to be implemented mechanism three
When executing opposite action, it is only necessary to change the oil liquid direction at P1 and P2.
In above process, extra oil liquid can be back in hydraulic oil container through oil return pipe.
And so on, solenoid valve block and executing agency can carry out in the manner described above it is multiple be superimposed, the number of executing agency
The quantity that amount is equal to solenoid valve block adds one, in addition to four actuator ports of the last one solenoid valve block connect Liang Ge executing agency,
Four actuator ports in remaining solenoid valve block, two actuator ports connect corresponding executing agency, other two actuator port
Connect the oil inlet of next solenoid valve block.
