The load signal that valve 63 is obtained is replicated by pressure, logic control can be carried out, do not affect load signal.
By pressure replicate valve 63 take out load signal, elimination system when starting the improvement stage, load pressure it is micro-
Amount declines.
When control banked direction control valves 42 is not operated, now load signal is zero, acts on the LS mouths that pressure replicates the left end of valve element 72
Communicate with P mouths, pressure replicates valve element 72 under the effect of LS pressure, overcomes back-moving spring 73 to move right, and closes P mouths and LS mouths,
Simultaneously LS mouths are connected with PL mouths, and LS mouth pressure is reduced to zero.
When control banked direction control valves 42 is operated, used as load signal, pressure replicates valve element 72 and exists now to fetch maximum load in road
It is moved to the left under the effect of load signal pressure, control banked direction control valves 42P mouths are connected with LS mouths, and it is real to replicate valve element 72 by pressure
When adjust the amount of opening of P mouths and LS mouths, make P mouth pressure be reduced to LS mouth pressure, act on the left end that pressure replicates valve element 72, work as LS
With during PL mouth pressure balances, now pressure replicates the holding dynamic balance state of valve element 72 to mouth pressure, and the moment makes LS mouths pressure and PL
Mouth pressure is equal.
The control banked direction control valves 42 has pressure copy function, can be arranged on existing valve body, compact conformation, no
Only meet the pressure and flow needed for operating mechanism, and the flow of actuator port can be made full use of, also can be to load signal
Logical design is carried out, the response speed of control banked direction control valves 42 is further improved, power conservation requirement is met.
