Compared with prior art, the beneficial effects of the utility model:
Step motor stator parts in the utility model are prior art, are not repeating at this.
The utility model in actual use, the rotating shaft guide cylinder hole and spool guide cylinder hole platform that communicate is formed in described valve base interior, wherein in described spool guide cylinder hole, spool is installed, spool upper end portion and rotor shaft are done to be flexible coupling, described rotor shaft is arranged in described rotating shaft guide cylinder hole, such valve inner configuration spool, when for regulating time, the rotation of spool and valve inner form space and are used for flowing medium, and on the sidewall in described spool guide cylinder hole, be provided with waist shaped hole, lower end surface, described rotating shaft guide cylinder hole is provided with cone shape hole, be equipped with in the lower end of described valve base seat and sidewall attachment hole and respectively with waist shaped hole, cone shape hole communicates, attachment hole is respectively equipped with connecting tube, what the utility model adopted is waist shaped hole and cone shape hole, the flowing of such medium is well controlled, on open market, we do the valve body that can see, on it, perforate is all rectangle, two ends turnover is equally large, such flow is difficult to control, so the utility model improves deficiency of the prior art at this point.
Spacing break is provided with in the outside of valve base seat in the utility model, combined and the coordinating of valve base seat by both, can be good at the spool of control valve base interior, in actual job, because the opening and closing of this valve is realized by the axial displacement of spool, and the axial displacement of spool is by being attached thereto the rotating shaft that connects under threaded function by converting rotary motion.For making the displacement amount of spool just must control the rotation number of turns of rotor in rational scope of design, namely spool axial displacement is limited.Thus have employed this spacing break.This break comprises the first spiral spring and the second spiral spring, and wherein the first spiral spring is fixedly connected with in valve body, and the second spiral spring can rotate freely and slide in the first spiral spring gap, but slides the structural limitations of the number of turns by the first spiral spring.So place restrictions on by the parallel end on the second spiral spring with its coaxial mounted rotor, because disrance sleeve inwall is provided with positioning strip, forward and reversely certain number of turns can only be rotated.
Valve core in the utility model is the regulative mode that is flexible coupling, namely rotor shaft is comprised, the inside of described rotor shaft forms cavity, Returnning spring is provided with in described cavity inside, port is provided with the bayonet socket connected for spool buckle, buckle one valve core rod in described bayonet socket, steel ball is provided with between described valve core rod and described Returnning spring, this Placement can prevent from rotor shaft axial seal force when being in closed condition from crossing the static friction power that the contact conical surface of ambassador's valve core rod and valve body produces being greater than the torque of motor and making motor by stall effectively, can also prevent in addition after valve core rod is in closed condition and follow axis of rotation, and make the sealing surface of valve body and valve core rod produce wearing and tearing.
As from the foregoing, the utility model compact structure, volume is little, and cost is low, is conducive to producing in enormous quantities, solves the problem that the numerical control flux valve Flow characteristics linearity is not good simultaneously, makes control procedure more accurate.
