Description

Technical Field

[0001] The utility model relates to the technical field of liquid level gauges, in particular to a magnetic flap liquid level gauge. Background Art

[0002] A magnetic flap liquid level gauge is a device used to measure the liquid level height of containers such as tanks and towers. It is connected to the container interface through a flange on one side of the pipe body. When the liquid level in the container rises and falls, the liquid pushes the magnetic float in the pipe body to move up and down. Since the magnetic flap indicator is magnetically coupled with the magnetic float, when the magnetic float rises and falls, it can drive the magnetic flap to rotate. The magnetic flap is used to distinguish the liquid level height by two colors, red and white, so that the liquid level in the container can be clearly observed. Therefore, the magnetic flap liquid level gauge is widely used by enterprises.

[0003] Most traditional metal containers such as steel containers contain iron components. When storing liquids for a long time, different degrees of corrosion will occur inside the container, and a small amount of iron filings will be generated. At the same time, a small amount of dirt deposits will also be generated when the liquid is placed in the container for a long time. The iron filings and dirt deposits generated during use will enter the pipe body and adhere to the magnetic float, causing an increase in the weight and volume of the magnetic float, affecting its normal up and down movement in the pipe body, thus generating reading errors. The long-term accumulation of dirt deposits will also cause pipeline blockage.

[0004] The existing Chinese patent with the application number CN202320191239.6 discloses a magnetic flap liquid level gauge. The application includes a pipe body, a magnetic flap indicator is arranged on the pipe body, a drain valve is connected to the bottom of the pipe body through a first flange, a magnetic float is arranged inside the pipe body, two branch pipes are arranged at positions near the upper end and the lower end on the surface of the pipe body, a detachable magnetic adsorption component is arranged on the branch pipes, a second flange is arranged on one side of the branch pipes, a filter screen is movably clamped inside the inner wall of the second flange, and a drain valve is arranged at the bottom of the pipe body. Although this liquid level gauge can filter and adsorb dirt and iron filings in the container through the filter screen and the magnetic adsorption component, since the filter screen is installed in the installation groove of the second flange, when replacing the filter screen, the second flange needs to be removed from the container to replace the filter screen, which is very troublesome.
