New structure pressure flow hybrid control valve.
Realize the technical solution of the utility model aim are as follows: a kind of new structure pressure flow hybrid control valve, by controller, electricity
Machine, shell, pressure sensor, spool, eccentric stiffener, machine shaft, linear Hall position sensor composition；
The spool is installed in shell, and the rotation of motor is converted into the straight line of spool by eccentric stiffener by motor
Displacement；The eccentric stiffener is made of eccentric rod and eccentric sphere, and eccentric rod is fixed together with rotor, and eccentric sphere is logical
It crosses clearance fit to be installed in the slot of spool, four oil-through-holes: oil inlet, oil return opening and two controls is opened up on the shell
Mouthful；Inside housings, quantity is two for the pressure sensor installation, the pressure being respectively used at two control mouths of measurement, and
Pressure signal is transferred to controller；Linear Hall position sensor arrangement converts the corner of motor in machine shaft upper end
Controller is fed back to for electric signal.
Compared with prior art, the remarkable advantage of the utility model are as follows: (1) spool position passes through rotating electric machine and eccentric machine
Structure directly drives, and no throttling pore contamination resistance is strong, high reliablity；(2) linear Hall position sensor, controller can collect
At that enclosure interior, compact-sized, control precision height.

The utility model is described in detail below with reference to embodiment.
Embodiment
In conjunction with Fig. 1, Fig. 2, a kind of novel pressure flow control valve is by controller 1, motor 2, shell 3, eccentric stiffener, Hall
Sensor, pressure sensor 4, spool 5 form.
The rotation of motor 2 is converted into the straight-line displacement of spool 5 by eccentric stiffener by the motor 2, and movement can
Lean on, contamination resistance it is strong；Motor is installed on the top of shell, controller can be integrated in motor inner housing according to requirements,
It can also separate with electric machine casing and individually be controlled.Machine shaft rear end is equipped with Hall sensor, and sensor turns motor
Angle is converted into electric signal and feeds back to controller.
The eccentric stiffener is made of eccentric rod and eccentric sphere 7, and eccentric rod is fixed together with rotor；It is described inclined
Heart bead small―gap suture is coupled in the slot in spool, and the pressure sensor is installed inside housings in a manner of poor dress, body
Product is small, and integrated level is high；Two limited blocks 6 are installed and carry out position limit in 5 both ends of spool.P corresponding with spool chamber is offered on shell
Mouth (oil inlet), A, B mouthfuls (control mouth), R mouthfuls (oil return opening).The controller processing signal includes rotor angle feedback signal,
Electrical-coil input signal, controller supply input, command input signals, the feedback signal of pressure sensor.
Working principle:
Signal includes that flow instruction and pressure limiting instruct, and when actual loading pressure is instructed lower than pressure limiting, pressure controller is defeated
Value is 0 out, is controlled based on flow instruction loading speed in system；When actual loading pressure is more than that pressure limiting instructs,
Pressure controller can issue a pressure limiting signal to weaken spool position control signal until load pressure is equal to or less than pressure limiting
Command signal.Due to installing two pressure sensors on valve chest, the pressure of a chamber (A mouthfuls or B mouthfuls) can be in use
It is fed back, can also be A mouthfuls and B mouthfuls of pressure difference and fed back.
