The fine motion valve shaft put is connected by hair, and by described fine motion valve shaft in fine motion valve body 14 moving up and down change micro-
Move the thrust to cone valve 12 for the spring.
Embodiment：Fine motion reversal valve of the present invention, is combined by commutation part and fine motion control parts two parts.
Described commutation part is by 2, three compression springs 3,4,5 of valve body, big piston 9, valve piston 6, spring 10 and steel ball
The compositions such as the individual event valve of 11 compositions, reversing shaft 7, reversing handle 8；Two cavitys being connected with big valve piston, i.e. A chamber and B chamber, leads to
Cross throttling pore to be connected.Three radial holes are provided with reversing shaft 7, and communicate with A chamber respectively.Flow out from three apertures
Fluid, by the oil duct on valve body 2, corresponding control gear I, gear II and neutral respectively.After fluid enters valve body 2, simultaneously
Reach A chamber and B chamber, in the presence of big piston 9 and valve piston 6, three compression spring 3,4,5 forced compression, formed in A chamber and set
Fixed pressure.When reversing handle 8 rotates, drive reversing shaft 7 to rotate, make working oil pass through different holes and flow out, reach commutation
Purpose.
Described fine motion control parts are by valve block 1, cone valve 12, hair 13, fine motion valve body 14, fine motion valve shaft 15 and micro-
Dynamic valve handle 16 grade composition.It is provided with helicla flute, under the drive of inching valve handle 16, fine motion valve shaft is permissible on fine motion valve shaft 15
Moving up and down in fine motion valve body 14, the thrust acting on cone valve 12 being changed by hair 13, thus adjusting B chamber
Pressure, A cavity pressure also changes therewith.When reaching a certain pressure value, clutch friction plate starts to skid.
Described fine motion reversal valve in the continuous rotation process of inching valve handle, can continuously by operating oil pressure from setting
Value is adjusted to minima.
The work process of the present invention is：When inching valve handle 16 is in off-position, cone valve 12 under spring force, is in
Closed mode, after fluid enters the A chamber of valve body 2, promotes valve piston 6 toward moving left, opens the spill port on valve body 2, and gush
A part of fluid, part fluid by throttling pore arrival B chamber, turn right and move to valve body 2 endoporus step by the big piston 9 of promotion simultaneously
Place, by large and small two piston effects, oil liquid pressure reaches and sets working pressure.Rotate reversing handle 8, drive reversing shaft 7
Rotation, pressure oil liquid passes through the different hole in valve body 2 bottom and flows out, and reaches different gear clutchs, reaches the purpose of commutation.This
When to enter into the oil liquid pressure value of clutch oil cylinder be to set working pressure, master and slave of clutch friction plate is fully engaged not
Skid, actuating device is worked with constant output speed.
When reversing handle is in any gear, rotary micromotion valve handle 16, drive fine motion valve shaft 15 to move upwards, fine motion
Spring 13 progressively reduces to the active force of cone valve 12, and cone valve 12 would be at opening, and part fluid passes through fine motion valve body 14
After return to fuel tank, B cavity pressure reduces, compression spring 3,4, and 5 decrement reduces, and the pressure in A chamber also declines therewith, rotary micromotion
When valve handle 16 arrives certain position, reduced pressure to critical point, clutch friction plate starts to skid, and is rotated further handle, pressure
Power continues to reduce in smaller range, and friction plate skid level persistently increases, and therefore output speed reaches the purpose of stepless time adjustment.
