Low liquid level quick-break switch device

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 [0001] The invention particularly relates to a low liquid level quick disconnect switchgear. Background technique [0002] Traditional liquid level switch devices generally use induction and magnetic float valve devices, and the magnetic float valve is used as the controller of the liquid level switch. When the liquid level drops, the magnetic float valve also drops. When the liquid level drops to a dangerous position , the magnetic float valve will drop accordingly, and drive the induction switch to disconnect the circuit to achieve the purpose of protecting the machine, but in actual situations, the above switches are usually installed on various machines for use. The vibration will cause the liquid level to fluctuate up and down. At this time, the magnetic float valve will also move up and down with the fluctuation of the liquid level. When the liquid level drops to a dangerous position, the up and down fluctuation of the magnetic f...

[0002] Traditional liquid level switch devices generally use induction and magnetic float valve devices, and the magnetic float valve is used as the controller of the liquid level switch. When the liquid level drops, the magnetic float valve also drops. When the liquid level drops to a dangerous position , the magnetic float valve will drop accordingly, and drive the induction switch to disconnect the circuit to achieve the purpose of protecting the machine, but in actual situations, the above switches are usually installed on various machines for use. The vibration will cause the liquid level to fluctuate up and down. At this time, the magnetic float valve will also move up and down with the fluctuation of the liquid level. When the liquid level drops to a dangerous position, the up and down fluctuation of the magnetic float valve will drive the induction switch to open frequently. Cause damage to the machine; moreover, the traditional liquid level switch device generally installs the induction switch and the magnetic float valve inside the liquid container and soaks it in the liquid. The induction switch is fixed and cannot be moved, which limits the control of the switch. The liquid level reduction stroke is very small, while reducing the accuracy of the controlled liquid level
