In addition, the quantity of pressure-regulating valve 2 is 2.
In addition, the quantity of pressure-regulating valve 2 is 3 or more than 3.Pressure-regulating valve 2 can be according to use demand certainly
Row is set.
Flow divider-combiner concrete operating principle of the present invention is as follows：Starting stage, pressure oil pushes up opening one-way by control mouth 39
Valve element 22 enters left spring chamber 32 and is applied to the left side of valve pocket 21, and pressure oil enters another by second channel 7 simultaneously
Individual pressure-regulating valve 2, pressure oil enters right spring chamber 33 by damper 23 simultaneously and is 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.Pressure correspondence in the open position of pressure-regulating valve 2
In the load pressure of maximum load pressure, the i.e. corresponding actuator port of pressure-regulating valve 2.
When the load of the actuator port of another pressure-regulating valve 2 becomes big, pressure oil, which can be flowed to preferentially, loads low pressure
The side of regulating valve 2, then can cause the pressure drop of restriction both sides different, and loading big pressure oil can be applied to by second channel 7
The left spring chamber 32 of the low pressure-regulating valve 2 of another pressure, the pressure of 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 mouthful 36, now from throttling
Pressure between 36 mouthfuls of the 5 to the first Regulation Control of mouth can be raised, untill valve pocket 21 reaches dynamic balance.So, 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 adjusted by the second Regulation Control mouthful 37 and first
Voltage-controlled donsole 36, pressure oil pushes up opening one-way valve element 22 by control mouth 39 and reaches left spring chamber 32, 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 for being applied to different pressure-regulating valves has the pressure oil pressure of mouth unequal, such as actuator port
When load pressure is low, the pressure of left spring chamber 32 can also be reduced, and the power of the left side of valve pocket 21 just diminishes, and valve pocket 21 will be to
Move left, the area of passage of the second Regulation Control mouthfuls 37 will reduce, now, before dynamic balance is reached pressure oil flow just by
Limitation, the pressure drop of final each actuator port to restriction 5 will be consistent.
Prior art is different from, flow divider-combiner of the present invention can be divided in portion flow, structure to some executing agencies
Simply, it is energy-efficient.
