In addition, the quantity of pressure-regulating valve 2 is 2.
In addition, the quantity of pressure-regulating valve 2 is 3 or 3 or more.Pressure-regulating valve 2 can be according to use demand certainly
Row setting.
Flow divider-combiner concrete operating principle of the present invention is as follows：Starting stage, pressure oil are open-top unidirectional by control mouth 39
Spool 22 enters left spring chamber 32 and is applied to the left side of valve pocket 21, and pressure oil enters by second channel 7 another simultaneously
A pressure-regulating valve 2, pressure oil enter right spring chamber 33 by damper 23 simultaneously and are applied to the right side of valve pocket 21,
Under oil liquid pressure and spring-force driven dual, valve pocket 21 is in an intermediate position.The pressure is corresponding in the open position of pressure-regulating valve 2
In maximum load pressure, i.e. the load pressure of the 2 corresponding actuator port of pressure-regulating valve.
When the load of the actuator port of another pressure-regulating valve 2 becomes larger, pressure oil, which can be flowed to preferentially, loads low pressure
2 side of regulating valve can then cause the pressure drop of restriction both sides different, and loading big pressure oil can be applied to by second channel 7
The pressure of the left spring chamber 32 of the low pressure-regulating valve 2 of another pressure, the left spring chamber 32 of pressure-regulating valve 2 is more than right bullet
The pressure of spring chamber 33, valve pocket 21 can move right, then can reduce the area of passage of the first Regulation Control mouth 36, at this time from throttling
Pressure between 36 mouthfuls of the 5 to the first Regulation Control of mouth can increase, until valve pocket 21 reaches dynamic balance.In this way, pressure oil port
Pressure it is constant, the pressure for flowing to different loads respectively by restriction 5 will be equal, flow also just it is equal, realize with load nothing
The assignment of traffic of pass.
When collecting stream mode, starting stage, pressure oil enters actuator port 8 and is adjusted by the second Regulation Control mouth 37 and first
Voltage-controlled donsole 36, pressure oil reach left spring chamber 32 by 39 open-top nonreturn valve core 22 of control mouth, and pressure oil is applied to valve pocket
21 left side, pressure oil enters another pressure-regulating valve 2 by second channel 7 simultaneously, while entering by damper 23
Right spring chamber 33 and the right side for being applied to valve pocket 21, under oil pressure and spring-force driven dual, valve pocket 21 is in an intermediate position.
When the work that is applied to different pressure-regulating valves have the pressure oil pressure of mouth it is unequal when, such as actuator port
When load pressure is low, the pressure of left spring chamber 32 can also reduce, and the power of the left side of valve pocket 21 just becomes smaller, and valve pocket 21 will be to
Move left, the area of passage of the second Regulation Control mouth 37 will reduce, at this point, before reaching dynamic balance pressure oil stream amount just by
The pressure drop of limitation, final each actuator port to restriction 5 will be consistent.
It is different from the prior art, flow divider-combiner of the present invention, flow, structure can be divided in portion to several executing agencies
Simply, energy-efficient.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
