Description
Technical field
The present invention relates to Liquid level device technical field, particularly relate to a kind of magnetic float switch.
Background technology
Float switch is a kind of structure Liquid level device simple, easy to use, and it does not need to provide power supply, does not have complicated circuit, the advantages such as it has less than common mechanical volume of switch, long working life.As long as material selection is correct during type selecting, the liquid of any character or pressure, temperature all can use, and it is obtained for and applies widely in shipbuilding industry, gen-set, petrochemical industry, food industry, water treatment facilities, Dyeing & Finishing Industry, oil pressure machinery etc.
Float switch mostly in the market is relay system or ball contact formula switch, the precise control of relay system float switch, is not subject to controlled fluids and damages, but installing cumbersome, major part situation needs two kinds of different potential circuits, realizes controlling low, high pressure with safe voltage; The installation of ball-type is simple, but switch block needs to be arranged on inside ball float, and with ball float one piece leaching in a liquid, the impact of liquid body, easily damages malfunctioning, and especially high-temp liquid or be with in corrosive liquid affects more obvious.
Summary of the invention
The technical assignment of technical problem to be solved by this invention and proposition improves prior art, provides a kind of magnetic float switch, and the traditional float switch solved in current technology installs inconvenience, the impact of liquid body, easily damages malfunctioning problem.
For solving above technical problem, technical scheme of the present invention is:
A kind of magnetic float switch, comprise floating lever and upper floating ball, it is characterized in that, described floating lever is vertically arranged, floating lever is fixed with flat thin magnet, iron plate and lower iron plate on being respectively arranged with above and below flat thin magnet, the upper surface of the upper and lower surface of flat thin magnet, the lower surface of upper iron plate and lower iron plate is provided with the contact of energising, the bottom device upper floating ball of floating lever.Magnetic float switch of the present invention utilizes the floating lever of device on upper floating ball to realize the control of liquid level, when liquid level declines, floating lever declines with upper floating ball, until flat thin magnet on floating lever and lower iron plate adsorb, fitting turning circuit in the electric shock of flat thin magnet lower surface and the contact of lower iron plate upper surface, controls feeding device to adding liquid in container; Liquid level in container rises gradually until flat thin magnet on floating lever and upper iron plate adsorb, and fitting turning circuit in the electric shock of flat thin magnet upper surface and the contact of upper iron plate lower surface, stops continuing to adding liquid in container.The present invention achieves automatic liquid level control simply and easily, and automatic supplementing liquid just can automatically stop to the amount of setting, precise control; And switch contact part of the present invention is positioned on liquid level, not the impact of liquid body, and switch contact part can not be corroded, and dependability is high, long service life.
Further, described upper floating ball is also connected with lower ball float by tightrope, and the structure that the present invention adopts upper floating ball to connect lower ball float effectively can shorten the distance between upper iron plate and lower iron plate, thus reduces the volume of switch contact part, make more compact structure, conveniently install and use.The adjustable length of the tightrope between upper floating ball and lower ball float, the liquid level controlled according to actual needs difference determines the length of tightrope, simply easy to adjust.When liquid level has just started to decline, the unsettled and lower ball float of upper floating ball has still floated when liquid level, and the weight of upper floating ball can not make flat thin magnet be separated with upper iron plate; Liquid level continues to decline, until when liquid level is lower than lower ball float, lower ball float plays the effect of effectively gaining in weight, the gravity of upper floating ball and upper floating ball and floating lever is greater than the magnetic attraction between flat thin magnet and upper iron plate, flat thin magnet and upper iron plate are effectively separated really, then flat thin magnet and lower paster are inhaled and are sticked together turning circuit, control feeding device to adding liquid in container, make to control more accurately, the length of the tightrope between upper floating ball and lower ball float accurately controls the height of required minimum liquid level.
Further, described upper floating ball is hollow seal ball, and make when liquid level rises upper floating ball have reliable buoyancy to promote floating lever and rise, the buoyancy magnetic attraction be greater than between flat thin magnet and lower iron plate of upper floating ball just can guarantee both to separate; And the density of upper floating ball material used is lower than the density of controlled liquid, even if make upper floating ball occur the situation of sealing leak like this, liquid after entering into upper floating ball inside the averag density of whole upper floating ball remain and be less than liquid, thus upper floating ball still has enough buoyancy promotes floating lever and rise.
Further, described lower ball float is sealed spheroid, and the density of material used, lower than the density of controlled liquid, utilizes lower ball float to control the height of minimum liquid level.
Further, described lower ball float inside is filled institute and control liquid, and the weight of ball float is descended in increase, makes the gravity of upper floating ball and upper floating ball and floating lever much larger than the magnetic attraction between flat thin magnet and upper iron plate, flat thin magnet and upper iron plate are effectively separated really.
Further, described upper iron plate and lower iron plate central aperture, floating lever is up and down through being led by perforate from the perforate of upper iron plate and lower iron plate, and the present invention utilizes iron plate and lower iron plate as the up and down guiding mechanism of floating lever, simplify structure, reduce cost of manufacture.
Further, described upper iron plate and lower iron plate adopt soft iron to make, soft iron is put into magnetic field exactly and is easily magnetized, after taking out magnetic field, demagnetize at once again, avoid iron plate and lower iron plate that magnetization occurs to cause the magnetic attraction of itself and flat thin magnet to become can not being efficiently separated out greatly, guaranteeing the long-acting normal work of switch contact part.
Further, described contact adopts copper contact, and copper has good electric conductivity, thus guarantees that magnetic float switch has good electric property, avoids the situation occurring loose contact.
Further, described floating lever adopts insulating material to make, and improves the electrical control accuracy of magnetic float switch, avoids floating lever conduction to occur electrically abnormal.
Compared with prior art, the invention has the advantages that:
Magnetic float switch of the present invention achieves the function controlling liquid level simply and easily, and precise control, contact part is positioned on liquid level, the not impact of liquid body, contact part can not be corroded, and dependability is high, long service life, be applicable to high temperature, corrosive environment, applied widely;
Magnetic float switch structure of the present invention is simple, and low cost of manufacture is easy to make, high financial profit.
