Description
Technical field
The present invention relates to Electromagnetic Control technology, be specifically related to a kind of method and device of calutron multiparty control.
Background technology
In prior art, middle of stroke, speed after calutron starts are all uncontrollable speed, and all quickly, this is because solenoid is the break-make of control coil electric current to usual keying speed.And the position of uncontrollable electromagnet pull bar, the position of pull bar is decided by mechanical structure completely, so usually only have two positions, logical and disconnected, and uncontrollable in centre position.
In the duct because the break-make of valve causes the change of velocity of medium, the change of flow velocity can cause again the change of pressure, especially cause the change of pressure larger when valve opens and closes fast, sometimes we even can hear in pipeline the sound having a kind of similar hammering, Here it is famous water hammer or gas hammer phenomenon.Sometimes the pressure oscillation that quick closedown causes can cause pipeline breaking, some important pipeline engineering, all to do the verification of this respect.
In daily life, we just have this cognition when using gas heater: when just having started to open water valve when you, water temperature is sometimes hot and sometimes cold, especially closed when you and opened again for a moment, start water temperature very high, then once turn cold again, and then heating is normal, when using piped gas, this phenomenon even more serious and lasting time is longer.This is due to when air valve is closed, the pressure loss is not had in pipeline, it is high when valve port place pressure ratio uses, firm higher when this higher pressure will allow gas flow rate compared with normal use when opening, more heat is produced during burning, so now temperature is high than usual, because gas has at pipeline and also has inertia, also only have and just produce flow velocity after mineralization pressure gradient in the duct, when after gas combustion above, gas below does not also flow through, decline fast with regard to build-up of pressure, the flow of gas declines, just cause the decline of calory burning, at this moment water temperature just reduces.Because the pipeline of piped gas is usually long a lot of than adopting the pipeline of liquefied gas, the time of this pressure wave transmission will be grown, and this phenomenon will be more obvious.
Known by electromagnetic knowledge and to be directly proportional to the electric current in its coil at the active force of the constant situation lower electromagnet of electromagnet structure, be also directly proportional to the number of turn of coil.In general electromagnet, because the gas length of valve block when diverse location on magnetic circuit is different, and magnetic conductance is the inverse of air gap, and magnetic flux is directly proportional to magnetic conductance again, and square being directly proportional of electromagnetic force and magnetic flux, so square being directly proportional of electromagnetic force and air gap inverse.Thus when in coil, during current constant, valve block is in diverse location, electromagnetic force is that difference is very large, and especially when the complete adhesive of valve block, air gap is 0, inhales very large, as long as now very faint electric current just can maintain this state.So general electromagnet is all this design, i.e. closed magnetic circuit now, benefit is large operating current when only need start, and then only needs that very small area analysis just can self-sustaining.Though so there is the effect of spring, each electric current cannot obtain the position of a balance, so the pull bar position of this electromagnet is uncontrollable.
Modern microchip throughout application bring a lot of convenience to numerous control circui.Very simple and convenient by the break-make of software controlled circuitry, a kind of by controlling that make-and-break time ratio is different thus the method realizing obtaining when input voltage is constant different average voltages obtains extensive use, this method is pulse width modulation, because English name is " Pulse Width Modulation ", so be called for short " PWM ".Well-known in the elastic limit of spring, the deflection of spring is directly proportional to added external force, this just famous Hooke's law.
Summary of the invention
The object of the invention is to, a kind of method of calutron multiparty control is provided, electromagnet pull bar position and the speed of keying can be controlled by the method for dynamic balance, thus position and the keying speed of the pull bar at electromagnet place can be controlled, electromagnet segmentation can be made like this to open and close, or gradually open and gradually close, also or rest on certain position.
The method applied in the present invention changes closed magnetic circuit into open magnetic circuit, and to reduce the impact of air gap change, because outside is without the soft magnet material (being generally iron or silicon steel) of magnetic conduction, the pull bar as armature can change permanent magnetic material into.
Present invention also offers a kind of calutron realizing said method.

Described control circuit is applied to the time scale of voltage on coil by changing, realize changing by electric current in coil, and changes magnetic force size and speed of action that this coil produces further.
A kind of multiparty control calutron realizing preceding method, it is characterized in that, it comprises a support, a coil, a pull bar, a permanent magnet, a back-moving spring, described coil is around on support, its inner hollow, described permanent magnet is fixedly installed on pull bar front portion, and pull bar afterbody is provided with a convex shoulder and an operate portions; Pull bar can do tandem motion under magneticaction in described coil inside hollow position; Described back-moving spring is set on described pull bar, and its front portion contacts with described support, its rear portion and described shoulder contact, and is fixed on this centre position by the two.
Described pull bar is nonmagnetic substance component, and described permanent magnet is fixedly installed in this pull bar by a gland.
Method provided by the invention, it just and between permanent magnet 14 will produce pulling force or thrust when coil charges excitation produces magnetic field, when producing pulling force, will holddown spring, until spring force and electromagnetic force equilibrium, when exciting current changes, electromagnetic force also changes, due to the effect of spring force pull bar pushed away or move new equilbrium position to, thus realize the object controlling pull bar position by controlling electric current, the speed of pull bar action is equally also just controlled by the speed of control break electric current.
