Abstract
The utility model relates to a liquid level switch quick-breaking device which is composed of a liquid container, a float ball which is arranged in the liquid container, a circuit switch, and a magnetic device which is arranged in the liquid container, wherein the float ball is steel float ball and is connected with the circuit switch, the magnetic device is arranged at a position which is positioned under the steel float ball and is corresponding to the steel float ball, and the magnetic device is arranged at the bottom of the liquid container. The utility model has the advantages that the magnetic device can make the steel float ball rapidly descend when the steel float ball is in a dangerous place with a certain low liquid level, so the circuit can be rapidly switched off by the switch; the fluctuation of the liquid level can not effect on the float ball; the utility model is designed slickly and has simple structure.
Description
Technical field
The utility model is particularly related to a kind of liquid level switch quick-break device.
Background technology
Traditional liquid-level switch device; the general controller that adopts ball float as liquid-level switch; when liquid level descends; floating ball device also descends thereupon; when liquid level is reduced to danger position; floating ball device will descend thereupon, and drive the switch open circuit, to reach the purpose of protection machine; but in actual conditions; above-mentioned liquid-level switch can be installed on the various machines usually and use, and when machine started, the vibrations of machine can make liquid level produce fluctuation up and down; at this moment floating ball device also can move up and down with the fluctuation of liquid level; when liquid level dropped to danger position, the fluctuation up and down of floating ball device can drive switch and frequently cut-off, and can cause the damage of machine.
Summary of the invention
The purpose of this utility model provides a kind of liquid level switch quick-break device, and it can avoid the influence of liquid fluctuating to ball float, thereby drives the rapid open circuit of switch, reaches the purpose of protection machine.
The technical solution of the utility model is: a kind of liquid level switch quick-break device, it is by liquid container and place its inner ball float and contactor to constitute, it is characterized in that: it also comprises the magnetic devices that is placed in the liquid container, above-mentioned ball float is the rigidity ball float, be connected with contactor, place magnetic devices with its opposite position below the rigidity ball float, this magnetic devices also is placed on the bottom of liquid container; When the magnetic float valve was reduced to dangerous liquid level with liquid, the attraction between rigidity ball float and magnetic devices will make the rigidity ball float descend rapidly, with magnetic means for engagement, had avoided the influence of liquid fluctuating to the rigidity ball float, made the rapid open circuit of switch.
The utlity model has following advantage: 1, adopt magnetic devices that the rigidity ball float is descended rapidly, make the rapid open circuit of switch when necessarily hanging down the liquid level danger position; 2, avoided the influence of liquid fluctuating to ball float; 3, design is ingenious, simple in structure.

Embodiment
As shown in the figure, a kind of liquid level switch quick-break device, it is by liquid container 4 and place its inner ball float 1 and contactor 3 to constitute, it is characterized in that: it also comprises the magnetic devices 2 that is placed in the liquid container 4, above-mentioned ball float 1 is the rigidity ball float, be connected with contactor 3, place magnetic devices 2 with its opposite position below rigidity ball float 1, this magnetic devices 2 also is placed on the bottom of liquid container 4; When magnetic float valve 2 was reduced to dangerous liquid level with liquid, the attraction that rigidity ball float 1 and magnetic devices are 2 will make rigidity ball float 1 descend rapidly, engages with magnetic devices 2, has avoided the influence of liquid fluctuating to rigidity ball float 1, makes the rapid open circuit of switch.
Operation principle: magnetic devices is placed in the bottom of liquid container, and when liquid was in the normal position, ball float drove switch and makes it to keep connecting circuit state; When liquid was in low liquid level danger position, ball float can descend rapidly under the effect of magnetic devices attraction, with magnetic means for engagement, drives switch open circuit immediately.
