Abstract
A quick-break switch of low liquid level is prepared as placing magnetic floating valve and magnetic unit in liquid container and setting magnetic unit in position corresponding to and under magnetic floating valve to use magnetism of said valve to induce induction switch for realizing on or off state of circuit, setting a pulling restorer above magnetic unit to pull magnetic floating ball to be at reset position for reconnecting induction switch through when liquid level is recovered to be at safety height.
Description
Technical field
The present invention be more particularly directed to a kind of low liquid level quick-break switch device.
Background technology
Traditional liquid-level switch device, general induction and the magnetic floating valve gear of adopting, with the controller of magnetic float valve as liquid-level switch, when liquid level descends, the magnetic float valve also descends thereupon, when liquid level is reduced to danger position, the magnetic float valve will descend thereupon, and drive inductive switch open circuit, to reach the purpose of protection machine, but in actual conditions, above-mentioned switch can be installed on the various machines usually and use, when machine starts, the vibrations of machine can make liquid level produce fluctuation up and down, and at this moment the magnetic float valve also can move up and down with the fluctuation of liquid level, when liquid level drops to danger position, the fluctuation up and down of magnetic float valve can drive inductive switch and frequently cut-off, and will cause the damage of machine; Have again, traditional liquid-level switch device, generally inductive switch and magnetic float valve are installed in liquid container inside, and be immersed in the liquid, inductive switch is fixing immovable, it is very little so just to limit the stroke that liquid level that this switch controls reduces, and has reduced the accuracy of controlled liquid level simultaneously.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of low liquid level quick-break switch device is provided.
Technical scheme of the present invention is: a kind of low liquid level quick-break switch device, it by magnetic float valve, magnetic devices, inductive switch, liquid container, lift restorer and constitute, above-mentioned inductive switch is fixed on the liquid container outer wall, no longer be immersed in the liquid, but and the height up and down of regulated at will inductive switch, to reach the size of the stroke of controlling the liquid level reduction, improved the accuracy of controlled liquid level simultaneously; Above-mentioned magnetic float valve and magnetic devices place in the liquid container, magnetic devices is positioned at the below of magnetic float valve opposite position, and be positioned at the bottom of liquid container, come the sensitive switch with the magnetic of magnetic float valve, realize the unlatching or the disconnection of circuit, when the magnetic float valve is reduced to dangerous liquid level with liquid, attraction between magnetic float valve and magnetic devices is greater than liquid buoyancy, the magnetic float valve is descended rapidly, with magnetic means for engagement, avoided the influence of liquid fluctuating, made the rapid open circuit of inductive switch the magnetic float valve; Above-mentionedly lift the top that restorer is placed on magnetic devices, when liquid level returns to safe altitude, use to lift restorer and the magnetic ball float is lifted reset, inductive switch recloses.
The present invention has the following advantages: 1, adopt magnetic devices that the magnetic float valve is descended rapidly when necessarily hanging down the liquid level danger position, avoided the influence of liquid fluctuating to the magnetic float valve, make the rapid open circuit of inductive switch; 2, inductive switch is placed on outside the liquid container, no longer is immersed in the liquid, but the height up and down of regulated at will inductive switch to reach the size of the stroke of controlling the liquid level reduction, has improved the accuracy of controlled liquid level.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention
Embodiment
As shown in the figure, a kind of low liquid level quick-break switch device, it by magnetic float valve 1, magnetic devices 2, inductive switch 3, liquid container 4, lift restorer 5 and constitute, above-mentioned inductive switch 3 is fixed on liquid container 4 outer walls, no longer be immersed in the liquid, but and the height up and down of regulated at will inductive switch, to reach the size of the stroke of controlling the liquid level reduction, improved the accuracy of controlled liquid level simultaneously; Above-mentioned magnetic float valve 1 and magnetic devices 2 place in the liquid container 4, magnetic devices 2 is positioned at the below of magnetic float valve 1 opposite position, and be positioned at the bottom of liquid container 4, come sensitive switch 3 with the magnetic of magnetic float valve 1, realize the unlatching or the disconnection of circuit, when magnetic float valve 1 is reduced to dangerous liquid level with liquid, the attraction that magnetic float valve 1 and magnetic devices are 2 is greater than liquid buoyancy, magnetic float valve 1 is descended rapidly, engage with magnetic devices 2, avoided the influence of liquid fluctuating, made inductive switch 3 rapid open circuits magnetic float valve 1; Above-mentionedly lift the top that restorer 5 is placed on magnetic devices 2, when liquid level returns to safe altitude, use to lift restorer 5 and magnetic ball float 1 is lifted reset, inductive switch 3 recloses.
Claims (1)
