Regulating step of the invention are as follows:
S1, control stepper motor 3 start, and the output shaft 31 of stepper motor 3 starts to rotate, and the output shaft 31 of stepper motor 3 drives
Spool 2 rotates；
S2, the first fixed plate 24, the second fixed plate 21, third fixed plate 22 are rotated with spool 2；
S4, the first arcuation track groove 211, the second arcuation track groove 221 are with the first fixed plate 24, the second fixed plate 21, third
Fixed plate 22 rotates, and the first arcuation track groove 211, the second arcuation track groove 221 and the first sphere 212, the second sphere 222 connect
Touching position changes；
S5, under the action of the first arcuation track groove 211, the second arcuation track groove 221, the first sphere 212, the second sphere 222
Position in the first linear track groove, the second linear track groove moves left and right；It is described when motor drives valve core rotation
Center of the sphere in linear track groove along center line transverse movement, far from or close to spool.When the first sphere 212 is mobile
When to the first linear track groove left end, the first sphere 212 squeezes the runner pipe 41 in the first horizontal through-hole, and first is horizontal
The runner pipe 41 set in through-hole is in closed state；When the first sphere 212 is moved to the first linear track groove right end, the first ball
Body 212 does not squeeze the runner pipe 41 in the first horizontal through-hole, and the runner pipe 41 in the first horizontal through-hole is in open state；
When the second sphere 222 is moved to the second linear track groove left end, the second sphere 222 is to the runner pipe in the second horizontal through-hole
42 are squeezed, and the runner pipe 42 in the second horizontal through-hole is in closed state；When the second sphere 222 is moved to the second linear track
When slot right end, the second sphere 222 is not squeezed the runner pipe 42 in the second horizontal through-hole, the stream in the second horizontal through-hole
Siphunculus 42 is in open state；
Work as valve core rotation, sphere moves under the action of arcuation track groove, along linear track groove to deep direction, right
Runner pipe generates squeezing action, and runner pipe inner section reduces, and runner pipe inner fluid speed reduces, until sphere is moved to most amphi position
When setting, runner pipe is squeezed completely, and circulation velocity in pipes will be zero, is equivalent to and is completely closed fluid passage；When sphere is in arcuation
Under the action of track groove, is moved along linear track groove to by paracentral direction, the squeezing action of runner pipe is gradually reduced,
Runner pipe inner section increases, and runner pipe inner fluid speed increases, until sphere is not to runner pipe when sphere is moved to proximal most position
Squeezing action is generated, completely, circulation velocity in pipes increases to maximum for runner pipe release, is equivalent to and fully opens fluid passage.
S6, different angles is rotated with the output shaft 31 of stepper motor 3, in the first horizontal through-hole, the second horizontal through-hole
Runner pipe 41,42 show different flow proportionals；When output shaft 31 turns to initial position, in the first horizontal through-hole
Runner pipe 41 is in complete relaxation state, and flow reaches maximum, and the runner pipe 42 in the second horizontal through-hole is in and squeezes completely
Pressure condition, flow are minimum；The flow proportional of runner pipe 41,42 in first horizontal through-hole, the second horizontal through-hole is 1:0；When
When the rotation of output shaft 31 is to 90 degree, the runner pipe 41 in the first horizontal through-hole is gradually squeezed, and the stream in the second horizontal through-hole
Siphunculus 42 is gradually loosened, and the flow of the two is mutually balanced, the runner pipe 41,42 in the first horizontal through-hole, the second horizontal through-hole
Flow proportional be 1:1；When output shaft 31 turns to 180 degree, the runner pipe 41 in the first horizontal through-hole is in be squeezed completely
State, flow is minimum, and the runner pipe 42 in the second horizontal through-hole is in complete relaxation state, and flow reaches maximum, the
The flow proportional of runner pipe 41,42 in one horizontal through-hole, the second horizontal through-hole is 0:1.Therefore, motor turns to different angles
Degree, flow corresponding to the runner pipe in the first horizontal through-hole, the second horizontal through-hole is different, and the flowrate proportioning of two-way fluid is not yet
It is identical, by adjusting motor rotational angle, it can get different flowrate proportionings, and two flow paths are completely independent, and will not mutually be produced
Raw interference.
During pipeline flow path reduces, the amplitude that flow velocity reduces can be gradually reduced, and be more convenient for controlling the stability of gas circuit；
Equally, during being opened and being gradually increased by completely closing, increased amplitude is gradually slowly increased by zero, is effectively reduced
For fluid to the percussion of pipeline, the flowing of fluid is more steady in opening procedure for flow path.And it is beaten completely when device is in
When open state neighbouring position, the velocity of displacement in transverse direction of sphere reaches maximum, and the change speed of fluid flow rate also increases
To maximum, it can guarantee that sphere to the compressional deformation effect of runner pipe, makes quick response to closing motion in this way.Namely
It says, in off position front and back, device can slowly adjust flow, to guarantee the stability of fluid；And before and after opening state, dress
It sets and quickly adjusts flow, to guarantee to change flow the quick response of state.
