Description
Technical field
The present invention relates to the valve body on a kind of numerical control flux valve.
Background technique
Along with the development of society, the progress of science and technology, growth in the living standard, simultaneously owing to being becoming tight energy day, energy-conservation aspect obtains very high attention.As the flow control element in control system, it is large that quantity control valve has flow adjustment range, and control accuracy is high, is applicable to the advantages such as intelligent control, applies more and more extensive.The quality of quantity control valve performance directly has influence on operation conditions and the energy-saving effect of whole system.The research of current logarithm control valve mainly concentrates on three aspects: testing property, controlling method and application study.And it is less for the research of the valve body self performance improved on numerical control flux valve.
The kind of quantity control valve is a lot, structure is also mostly different, but the form of its throttle structure is then similar, mainly cone valve structure, we know that throttle structure directly determines Flow characteristics, and its linearity of the Flow characteristics of cone valve structure is undesirable, namely when condition certain (pressure reduction is certain), flow and aperture are not proportional relation, but become curved line relation, close to quadratic curve.One of them affected factor is valve body structure, so this current valve body needs to be improved.
Summary of the invention
The object of the invention is the valve body in order to provide on a kind of numerical control flux valve, compact structure, valve body is accurately convenient, easy to use to controlling in spool adjustment process simultaneously.
For achieving the above object, technological scheme of the present invention is:
Valve body on numerical control flux valve, it is characterized in that: comprise valve base seat, described valve base interior forms the rotating shaft guide cylinder hole and spool guide cylinder hole platform that communicate, the sidewall in described spool guide cylinder hole is provided with waist shaped hole, lower end surface, described rotating shaft guide cylinder hole is provided with cone shape hole, be equipped with attachment hole in the lower end of described valve base seat and sidewall and communicate with waist shaped hole, cone shape hole respectively, attachment hole is respectively equipped with connecting tube.
The present invention is done further preferably, the outer wall of described valve base seat forms annular convex ring, between described annular convex ring and described valve base seat, forms annular snap.
The present invention is done further preferably, also comprise the spacing break being socketed in described valve base outer wall, described spacing break comprises the first spiral spring and the second spiral spring, and described first spiral spring one end forms the right angle bends of vertical circle body, and the other end forms vertical component effect that is vertical and circle body; Described second spiral spring one end forms the parallel end of flat shape and circle body; When mounted, when described second spiral spring is snapped in the first spiral spring, the parallel end of described second spiral spring is positioned at top, and the other end is positioned at below and offsets with described vertical component effect.
Compared with prior art, beneficial effect of the present invention:
The present invention 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 present invention 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 present invention improves deficiency of the prior art at this point.
Spacing break is provided with in the outside of valve base seat in the present invention, 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.
As from the foregoing, compact structure of the present invention, valve body is accurately convenient, easy to use to controlling in spool adjustment process simultaneously.
In order to explain technological scheme of the present invention further, below by specific embodiment, the present invention will be described in detail.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention.
Fig. 2 is the structural representation of spacing break in the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
With reference to accompanying drawing 1 and accompanying drawing 2, present embodiment discloses the valve body on a kind of numerical control flux valve, it is characterized in that: comprise valve base seat 1, described valve base seat 1 inside forms the rotating shaft guide cylinder hole 2 and spool guide cylinder hole platform 3 that communicate, the sidewall in described spool guide cylinder hole 3 is provided with waist shaped hole 4, lower end surface is provided with cone shape hole 5, be equipped with in the lower end of described valve base seat 1 and sidewall attachment hole and respectively with waist shaped hole 4, cone shape hole 5 communicates, attachment hole is respectively equipped with connecting tube 6, the outer wall of described valve base seat 1 forms annular convex ring 7, annular snap 8 is formed between described annular convex ring 7 and described valve base seat, the present invention also comprises the spacing break 9 being socketed in described valve base seat 1 outer wall, described spacing break 9 comprises the first spiral spring 10 and the second spiral spring 11, described first spiral spring 10 one end forms the right angle bends 12 of vertical circle body, the other end forms vertical component effect 13 that is vertical and circle body, described second spiral spring 11 one end forms the parallel end 14 of flat shape and circle body, when mounted, when described second spiral spring 11 is snapped in the first spiral spring 10, the parallel end 14 of described second spiral spring 11 is positioned at top, and the other end is positioned at below and offsets with described vertical component effect 13.
