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] The magnetic flap level gauge is a liquid level measuring instrument developed based on the buoyancy principle and magnetic coupling. When the liquid level in the measured container rises or falls, the magnetic float in the main tube of the level gauge also rises or falls. The float is made of a material with buoyancy characteristics, such as plastic or stainless steel. According to Archimedes' principle, the buoyancy is equal to the gravity of the liquid. The permanent magnet in the float is transmitted to the magnetic flip column indicator through magnetic coupling, driving the red and white flip columns to flip 180°. When the liquid level rises, the flip column changes from white to red; when the liquid level drops, the flip column changes from red to white. The red and white intersection of the indicator is the actual height of the liquid level inside the container.

[0004] There are some problems with this type of traditional magnetic flap level gauge. For example, the fixed position of the installation unit may limit the installation scope of the magnetic flap level gauge, which may further affect the installation scope of the magnetic flap level gauge.

The operation of the liquid level control switch 10 is realized through the single-chip microcomputer 12. The upper alarm point 6 and the lower alarm point 7 monitor the warning liquid level state inside the external device. When the liquid level reaches the upper alarm point 6 and the lower alarm point 7, the liquid level control switch 10 sends a warning message to the single-chip microcomputer 12, and the liquid enters the interior of the main conduit 1 through the connecting pipe 2 4, so that the float 13 slides upward inside the main conduit 1 under the action of buoyancy. As the float 13 moves upward, the permanent magnetic column 14 causes the magnetic flip column 8 experienced by the float 13 to flip, and the magnetic flip column 8 and the scale bar 9 correspond horizontally to display the liquid level information;

The backward movement of the drive cylinder 56 pushes the longitudinally adjacent drive disk 55 to move backward. The drive disk 55 pushes the front end of the connecting rod 54 to move backward, so that the rear end of the connecting rod 54 pushes the corresponding sliding block 53. The sliding block 53 slides in the corresponding slide groove 52 in the direction away from the center of the installation disk 51. When the sliding block 53 moves to the required position, the personnel stops rotating the drive cylinder 56, and then bolts the installation hole and the working area together. The threaded holes are stably connected, thereby realizing stable installation of the magnetic flap level gauge. After the installation is stable, the personnel realize the operation of the liquid level control switch 10 through the single-chip microcomputer 12. The upper alarm point 6 and the lower alarm point 7 monitor the warning liquid level status inside the external device. When the liquid level reaches the upper alarm point 6 and the lower alarm point 7, the liquid level control switch 10 sends a warning message to the single-chip microcomputer 12, and the liquid enters the interior of the main conduit 1 through the connecting pipe 2 4, so that the float 13 slides upward inside the main conduit 1 under the action of buoyancy. As the float 13 moves upward, the permanent magnet column 14 causes the magnetic flip column 8 that the float 13 experiences to flip, and the magnetic flip column 8 and the scale bar 9 correspond horizontally to display the liquid level information.
