Description

Technical Field

[0001] The utility model belongs to the technical field of liquid level gauges, and particularly relates to an alarm type liquid level gauge. Background Art

[0002] The magnetic flip plate liquid level gauge is made according to the buoyancy principle and magnetic coupling action. When the liquid level in the measured container rises or falls, the magnetic float in the liquid level gauge body tube also rises or falls accordingly. 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 degrees. When the liquid level rises, the flip column changes from white to red, and when the liquid level falls, the flip column changes from red to white. The red-white junction of the indicator is the actual height of the liquid level inside the container, thus realizing clear indication of the liquid level.

[0003] In actual work, to ensure operation safety and prevent the occurrence of situations such as the storage tank overflowing or being emptied, it is necessary to constantly monitor and keep an eye on the liquid level, consuming a lot of personnel energy. Existing magnetic flip plate liquid level gauges with alarm functions, such as a magnetic flip plate liquid level gauge with an alarm function disclosed in Chinese Patent CN201822088464.9, which relates to the technical field of magnetic flip plate liquid level gauges, includes a first pipe and a second pipe. The circumferential surface of the first pipe is respectively fixedly connected with an upper drainage pipe and a lower drainage pipe; one end of the upper drainage pipe and one end of the lower drainage pipe are both fixedly connected with a first fixed flange; the circumferential surfaces of the upper drainage pipe and the lower drainage pipe are both rotatably connected with a first control valve; the lower surface of the first pipe is fixedly connected with a second fixed flange; the second fixed flange is fixedly connected with a third fixed flange through bolts; a first sewage discharge pipe is fixedly connected to one surface of the third fixed flange; the circumferential surface of the first pipe is respectively fixedly connected with a first circular pipe and a second circular pipe. By setting the first pipe, the problem that the existing magnetic flip plate liquid level gauge has no alarm function is solved; by setting the spiral blade, the problem that sewage sprays during sewage discharge of the existing magnetic flip plate liquid level gauge is solved.

[0004] Existing magnetic flip plate liquid level gauges with alarm functions can give an alarm when the liquid level reaches the upper limit or the lower limit, but the upper limit and the lower limit are fixed values and it is not convenient to change the alarm value. Summary of the Utility Model
