As improvement of the technical scheme, be connected by a thrust ball bearing between the inner of described screw rod and the spring base.Thrust ball bearing both can transmit the axial thrust of screw rod to spring base, was convenient to screw rod again and rotated with respect to spring base.
As improvement of the technical scheme, described valve seat front end is provided with pressure transmitter, and this pressure transmitter and described motor are connected with a controller simultaneously.Controller can be controlled motor according to the actual pressure value that pressure transmitter collects, and reaches required pressure thereby drive pressure regulating device, so just can realize the automatic control of homogenization pressure, pressure regulation is reliable, precision of voltage regulation height, good reproducibility, and can realize Long-distance Control.
Preferably, the outer end of described screw rod is provided with a connecting portion, and this connecting portion is connected with a gear wheel, and described gear wheel is meshed with a pinion, and described pinion is connected with described motor by decelerator.This transmission mechanism has guaranteed the accurate transmission of motor to screw rod.
As the improvement to above-mentioned preferred version, described screw rod matches with a hard-wired round nut, and described gear wheel is enclosed within the outside of described round nut, and can move axially along round nut.
As improvement to above-mentioned preferred version, the first sensor and second sensor that are connected with described controller also are installed near gear wheel, described gear wheel is provided with the first triggering portion and the second triggering portion that can trigger these two sensors respectively.This structure can limit the extreme position of pressure regulating device, guarantees that pressure regulating device moves in the scope of a safety.

Further, described screw rod is a cored screw, and an end of described push rod stretches out from cored screw, and is provided with clamp nut in its end.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structure chart of a kind of homogenizer homogenization pressure of the utility model adjusting device.
The specific embodiment
As shown in the figure, the valve body of homogenizer 1 is connected with a low pressure pressure regulating device with a high pressure pressure regulating device simultaneously, below earlier the high pressure pressure regulating device is described.
The front end of spool 3 is relative with the end face of valve seat 2, and the gap between them has just constituted the aperture of valve, and valve opening is big more, and the pressure P in the valve seat 2 is just more little; Valve opening diminishes, and plunger displacement pump will make pressure P become big.
Screw rod 16 withstands on the back of spring base 19, is connected by a thrust ball bearing 18 between the inner of screw rod 16 and the spring base 19.Screw rod 16 matches with round nut 17, and round nut 17 is fixedly mounted on the rear end of handwheel seat 4.
Below the pressure regulation process is described.
One, the process of boosting:
Two, stress-relief process:
If motor 5 clockwise rotates, drive screw rod 16 and retreat by pinion 8, gear wheel 15, the connecting portion 14 of screw rod is by the motion backward fast of clamp nut 13 pulling push rods 21.When the second triggering portion 12 on the gear wheel 15 contacts with second sensor 9, stop operating by controller control motor 5, compress spring 20 and automatically reset this moment, homogenizer pump housing internal pressure P promotes high pressure spool 3 and moves backward, the aperture of 3 of high pressure seat 2 and high pressure spools is increased, finish the fluid admittance, the pressure differential return-to-zero of at this moment high-pressure homogeneous valve place, so far, stress-relief process is finished.
The low pressure pressure regulating device also is by driven by motor push rod motion, changes the aperture between spool 23 and the valve seat 22, thereby plays the effect of regulating the low pressure homogenization pressure, and its structural principle, mechanism are identical with above-mentioned high-pressure section, no longer detailed description.
