Abstract
The utility model relates to a bistable and pulse-control electromagnetic valve of a self-operated valve system, which controls the open and close of gas or liquid. Two pieces of permanent magnet iron are arranged laterally on a wire package. With repelling homopolarity, the permanent magnet is fixed at a certain position. The utility model has the advantages of lower power dissipation, steady performance as well as simple processing technique.
Description
Affiliated technical field:
The utility model is the bistable state pulse control type electromagnetic valve device in a kind of controlling liquid or the gas self-powering type valve system opening and close, is that a kind of preparation process is simpler, more stable work, reliable, the bistable state pulse control type solenoid valve that power consumption is lower.
Background technique:
At present, known bistable state pulse control type solenoid valve (promptly driving the solenoid valve that keeps automatically behind the electromagnetic valve core with transient pulse) structure has following several: Fig. 3 is a kind of lower end that permanent magnet are installed online bag, and the spool the other end is with the solenoid valve of a driving spring.Because when this kind solenoid valve will be in the downward steady state of spool, must be by the elastic force of spring.So when the downward steady state of spool becomes the steady state that spool makes progress, must overcome the elastic force of driving spring.Thereby this kind solenoid valve needs bigger driving power just can guarantee reliably working, if the cell voltage fluctuation can cause electromagnetic force can not overcome spring force effectively, solenoid valve can not reliably working.Fig. 4 a kind ofly is placed on line bag top with permanent magnet, this kind structure, and two soft magnetic cores are unequal to the magnetic force of spool up and down.Thereby solenoid valve also must rely on the elastic force of spring could guarantee that solenoid valve is in the steady state of automatic maintenance will be in the downward steady state of spool the time.So when the downward steady state of spool becomes the steady state that spool makes progress, also have the problem that solenoid valve can not reliably working at solenoid valve.Fig. 5 is that another kind is installed the middle solenoid valve of online bag with permanent magnet, this kind solenoid valve is because the line bag will be in two, so the electromagnetic force of the line packet generation of equal volume can be littler, make solenoid valve become the steady state that spool makes progress from the downward steady state of spool, power consumption is relatively large, and complex manufacturing technology.
Summary of the invention:
For the bistable state pulse control type electromagnetic valve device complex process, the power consumption that overcome in the self-powering type valve system that existing controlling liquid or gas opens and close big, the deficiency of unstable properties, the utility model provides a kind of brand-new structure, make processing technology simpler, service behaviour that the more important thing is solenoid valve is more stable, and power consumption is lower.
The technological scheme that its technical problem that solves the utility model adopts is: with the both sides (inboard of coil brace) that two permanent magnets are placed online bag respectively, permanent magnet is fixed.Two permanent magnets are parallel, homopolarity is relative, permanent magnet is installed in an appropriate position, magnetic conduction by coil brace, two kinds of upper and lower steady state driving powers are equated, do not need to rely on the elastic force of spring, so the utility model from the steady state of steady state under becoming the time solenoid valve can not need bigger power consumption because needs overcome the extra elastic force of spring so that can not make the solenoid valve can not reliably working because of the fluctuation of cell voltage.The groove of spool both sides processing be for prevent spool when the work from a kind of steady state become another kind of steady state moment liquid or gas spool is produced resistance.The center of spool processes a hole, and a little spring is contained in the hole, and this spring only plays the interference of counteracting rubber size and the effect of auxiliary seal.
The beneficial effects of the utility model are not need extra power consumption during solenoid valve work, so working stability.Need only be with the outside of the fixing online bag of permanent magnet, polarity is relative, and preparation process is simple.
