Description

Technical Field

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

[0002] The magnetic flap level gauge is a measuring instrument used to detect the liquid level of a container. It consists of a liquid level tube, a magnetic flap display mechanism, a magnetic float, an upper connecting pipe, a lower connecting pipe and a sewage pipe. When the liquid level in the measured container rises or falls, the magnetic float in the liquid level tube also rises or falls. The magnetic float drives the red and white flip columns to flip 180° through the principle of magnetic coupling, and the color change of the red and white flip columns is used to read the liquid level. When the liquid level rises, the flap changes from white to red, and when the liquid level drops, the flap changes from red to white. The red and white intersection of the indicator is the actual height of the liquid level inside the container.

[0003] Magnetic flap level gauges are widely used in chemical, petroleum, metallurgy and other fields. However, in actual application, sometimes the magnetic flap level gauge may have a fault problem, that is, the magnetic flap of the level gauge cannot be turned over normally, and then the magnetic flap level gauge needs to be repaired.

[0004] However, since the storage tanks in chemical plants are generally high and the existing maintenance tools are not designed reasonably, workers are required to climb up to a height for maintenance, which poses a safety risk and is inconvenient to operate. Utility Model Content

[0037] A handle 141 is disposed on the side of the housing 110 away from the motor 140 to facilitate workers to hold and use the maintenance tool 10 .

[0038] The upper guide tube 120 and the lower guide tube 130 are circular tubular structures, respectively disposed at the top and bottom of the housing 110 , and are used to guide the screw rod 150 .
