Rectangular channel 219 is provided among 204 upper surface of sliding block, 219 slot of rectangular channel is interior to be provided with the first bullet along center of circle direction side
Spring hole 206；First spring eye, 206 the inside is placed with the first spring 205, the square block 207 of the first spring 205 and spool bottom
It is connected.Spool includes the assembly of three same sections, wherein there are two feedback regulation device 1 is carried, respectively passes through nut 108
With leading screw 106) it is connected；Assembly be include arc-shaped cavity 209, second spring 213, arc-shaped cover board 210 and with circle
The matched telescopic block 214 of arc cavity, cover board 210 are sealed against by screw 211.Such three parts assembly head and the tail phase
Mutually embedded composition spool, when being moved radially with the matched sliding block of 202 guide rail of bevel gear wheel 204, the first bullet in sliding block 204
Spring 205 deforms；Since stress needs to balance, so driving three spool radial directions respectively under the action of the first spring 205
Movement；The radial motion of spool can make the telescopic block 214 in its cavity under the action of internal second spring 213 along the circumferential direction
Occur to stretch, to which three mutually embedded identical arc-shaped assemblys along the circumferential direction occur to stretch, and then changes spool
The size of opening area.According to setting flow, determining choke area is obtained.
It is flow-compensated：When the flow-rate adjustment of fluid is to a setting value, if Fluid pressure or temperature change, stream
Body flow needs to compensate；Mounted on the pressure sensor of fluid inlet 305 or the pressure and temperature of temperature sensor monitors fluid
Degree, if pressure and temperature changes, corresponding signal passes to microcontrol processor, and microcontrol processor is implemented by calculating
Temperature and pressure compensation, this signal drives feedback regulation device 1 by transmission device, adjusts throttling spool open area, after obtaining compensation
Valve core opening size；Transmission device drives driver 101, has self-locking spring 103 in the rectangular slot 102 of driver 101,
The both ends of self-locking spring 103 are in rectangular slot 102, and the outer wall of self-locking spring 103 and leading screw 106 has slight friction, silk
Thick stick 106 passes through self-locking spring 103, driver 101, and coaxial, and the front end of leading screw 106 has screw thread 107 to match with hex nut 108
It closes；When driver 101 does not turn, although self-locking spring 103 has friction with leading screw 106, it can occur to slide relatively, leading screw 106
It can move back and forth along valve core diameter direction.Driver 101 turns left, and acts on one end of self-locking spring 103, outside self-locking spring 103
Diameter reduces, and blocks leading screw 106, and leading screw 106 is driven to turn left；Driver 101 is turned right, and the other end of self-locking spring 103 is acted on, from
103 reduced diameter of spring is locked, leading screw 106 is blocked, leading screw 106 is driven to turn right.
Leading screw 106 is connected by screw 110, hex nut 108, pin 109 with spool.Leading screw 106 rotates, and leads to
Nut 108 is crossed, leading screw 106 is changed into moving radially for nut 108.Nut 108 is by pin 109 with movable valve plug
One assembly moves radially, and the telescopic block 214 in its cavity is made along the circumferential direction to be sent out under the action of internal second spring 213
It is raw flexible, to which three mutually embedded identical arc-shaped assemblys along the circumferential direction occur to stretch, and then adjusts spool and open
The size of open area realizes compensation.
When setting flow, regulate transmission device drives spool, and when changing choke area, driver 101 does not rotate.Leading screw
There is gap between 106 and self-locking spring 103, friction coefficient very little can opposite sliding between them.At this moment, assembly can be with
It drives hex nut 108 and leading screw 106 to move radially, is not influenced by self-locking spring 103.
When flow-compensated, for setting flow it has been determined that regulate transmission device is in fixed position, spool is determining opening,
At this moment flow-compensated, driver 101 rotates, and self-locking spring 103 locks leading screw 106 and rotated together with driver 101, passes through six
Angle nut 108 drives assembly to move radially.Assembly be by the first spring 205 and 204 elastic connection of sliding block, can be opposite
Sliding block 204 moves, and to change choke area, realizes compensation.
The embodiment is the preferred embodiments of the present invention, but present invention is not limited to the embodiments described above, not
Away from the present invention substantive content in the case of, those skilled in the art can make it is any it is conspicuously improved, replace
Or modification all belongs to the scope of protection of the present invention.
