Anti-freezing magnetic flip plate liquid level meter

Abstract

An anti-freezing magnetic flip plate liquid level meter comprises a flange, wherein an outer stainless steel sleeve is fixedly arranged on the flange, and a flip plate type height scale is arranged on the outer surface of the outer stainless steel sleeve. The anti-freezing magnetic flip plate liquid lever meter is characterized in that an inner stainless steel sleeve is arranged in the outer stainless steel sleeve, a vacuum layer is formed between the outer stainless steel sleeve and the inner stainless steel sleeve, a stainless steel connecting rod is arranged in the inner stainless steel sleeve, a floating ball is arranged at the bottom of the stainless steel connecting rod, a magnetic sliding block is arranged on the top of the stainless steel connecting rod, and the stainless steel connecting rod is filled with a phase change medium or a heat conducting medium. The anti-freezing magnetic flip plate liquid level meter has the advantages that the inner stainless steel sleeve is arranged in the outer stainless steel sleeve, the vacuum layer is formed between the outer stainless steel sleeve and the inner stainless steel sleeve, and thus the heat preservation effect is achieved; the stainless steel connecting rod is filled with the phase change medium or the heat conducting medium, the heat of liquid in a container can be conducted to the magnetic sliding block through the medium, the temperature of the magnetic sliding block and the temperature of the liquid in a tank can be kept consistent, it can be ensured that the magnetic sliding block is not frozen as long as the liquid in the container is not frozen, and it is ensured that the liquid level meter works normally.

Description

technical field [0001] The invention relates to an instrument for measuring the liquid level height in a container, in particular to an antifreeze magnetic flap liquid level gauge. Background technique [0002] The magnetic flap level gauge is a mature instrument for measuring liquid level. It is mainly composed of a flange and a stainless steel jacket set on the flange. It is set inside the stainless steel jacket with a floating ball at the bottom and a magnetic slider at the top. The stainless steel connecting rod and the flip-type height scale set on the stainless steel jacket are composed. [0003] The liquid level in the container rises or falls, and the floating ball moves with the rising or falling of the liquid level, drives the magnetic slider to move through the connecting rod, and drives the magnetic flap to turn over, and the change of the liquid level can be known. Just complete the work of measuring the liquid level. [0004] The problems in the actual work o...

AI Technical Summary

Problems solved by technology

[0004] The problems in the actual work occur in winter, the winter temperature in the north is below zero, the stainless steel tube of the magnetic flap liquid level gauge is exposed to the cold air, there is water vapor in the stainless steel tube to form condensation, and it freezes at low temperature, resulting in The magnetic slider is frozen in the stainless steel tube and cannot slide normally

In this way, the liquid level cannot be displayed normally when the liquid level changes.
