Description

Technical Field

[0001] The invention discloses a magnetic flap liquid level gauge anti-blocking device, belonging to the technical field of liquid level gauges. Background Art

[0002] The core component of the magnetic flap level gauge is a magnetic float, which moves up and down in the measuring tube as the liquid level changes. The float is equipped with a permanent magnet inside, which can generate a magnetic field in the measuring tube. A row of flaps are installed on the outside of the measuring tube, and each flap has a small magnet. When the float rises or falls with the liquid level, the magnetic field of the float will affect the magnet on the flap, causing the flap to flip and display different colors, usually red for the liquid level part and white for the part without liquid level. By observing the color change of the flap, the height of the liquid level can be directly read. At present, the liquid phase inlet and gas phase inlet of the magnetic flap level gauge are directly connected to the liquid storage tank. Impurities in the liquid in the liquid storage tank can easily enter the magnetic flap level gauge, resulting in an increase in the resistance to the movement of the float, which makes the liquid level indication have errors. Therefore, it is necessary to design a magnetic flap level gauge anti-blocking device. Summary of the invention
