Hydraulic principle and the control banked direction control valves with pressure duplication valve element as shown in Figure 4,5 for control banked direction control valves 42 enters
Mouthful piece, control banked direction control valves 42 includes the work connection 68, shuttle valve of the first the 66, the 3rd work connection of work connection the 65, second work connection the 67, the 4th
59th, pressure replicates valve 63 and relief valve 64, and the pressure replicates valve 63, the oil-in of relief valve 64 and is connected to control banked direction control valves
42P mouths, the oil-out of relief valve 64 is connected to T mouths, takes from the 4th work 68 actuator port A of connection4And B4The load signal of mouth passes through
Valve core inside oil duct enters the oil-in E mouths and F mouths of shuttle valve 59, and by shuttle valve 59 the higher pressure of pressure in E mouths and F mouths is gathered
Oily Jing oil-outs G mouths are output as load signal, act on the valve element right-hand member that pressure replicates valve 63, control the P mouth pressures of banked direction control valves 42
Power oil replicates Jing pressure and the valve element left end that pressure replicates valve 63 is acted on after valve 63 reduces pressure, and Jing pressure the letter after valve 63 reduces pressure is replicated
Number be feedback signal, pass the Variable Control hydraulic fluid port X mouths of hydraulic oil pump 4 by feedback signal hydraulic fluid port LS oral instructions.
It is hydraulically-controlled type proportioning valve that the pressure replicates valve 63, and pressure replicates valve 63 and relief valve 64 is integrated in control banked direction control valves
On 42 import piece, pressure replicates the valve element two ends area equation of valve 63, and pressure replicates the valve element right-hand member of valve 63 and is provided with back-moving spring
73。
The control process for controlling banked direction control valves 42 is：
4th work connection 68A4Or B4The load signal of mouth enters the E mouths and F mouths of shuttle valve 59 by valve core inside oil duct, leads to
Cross the higher pressure oil Jing G mouths of pressure in the collection E mouths of shuttle valve 59 and F mouths and act on the pressure duplication right-hand member of valve element 72, answer pressure
Valve element processed 72 is moved to the left under the effect of load signal pressure, and the P mouths for controlling banked direction control valves 42 replicate valve 63 and LS mouths through pressure
Connect；
The amount of opening of the real-time adjustment P mouth of valve element 72 and LS mouths is replicated by pressure, P mouths pressure drop is made and is acted on pressure
The left end of valve element 72 is replicated, the pressure signal after valve 63 reduces pressure is replicated by pressure and is feedback signal；
The real-time adjustment of valve element 72 is replicated by pressure, the feedback signal of LS mouths and the load signal phase of PL mouths is always ensured that
Deng X mouth of the pressure signal transmission that Jing pressure duplication valve 63 is replicated to hydraulic oil pump 4.
It is a hydraulically-controlled type proportioning valve that pressure replicates valve 63 in the control banked direction control valves 42, and by pressure valve element 72 is replicated
Real-time action, is always ensured that the feedback signal of LS mouths is equal with the load signal of PL mouths.
Pressure replicates the two ends area equation of valve element 72, internal processing channel, and the rigidity of back-moving spring 73 is little, only rises multiple
Position effect, its spring force is negligible.
The load signal of the control banked direction control valves 42 can be measured by PL mouths.
The feedback signal of the control banked direction control valves 42 can carry out external logic control.
The pressure oil of the P mouths of the control banked direction control valves 42 replicates valve 63 and flows directly into LS mouths by pressure, improves system
Response speed.
The feedback signal fluid of hydraulic oil pump 4 is passed to from the P mouths of control banked direction control valves 42, is not consumed in actuator port
Fluid.
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.
