Description

Technical Field

[0001] The utility model relates to the technical field of liquid level measurement, in particular to a self-balancing low-density magnetic levitation liquid level gauge. Background Art

[0002] The magnetic float level gauge is a measuring instrument that uses a magnetic float as a sensing element and reflects the measured liquid level or interface through the coupling effect between the magnetic float and the magnetic body in the display color bar. Its principle is to form a communicating vessel with the measured container to ensure that the liquid level between the measured container and the measuring tube body is equal. When the float in the measuring tube of the level gauge changes with the measured liquid level, the magnetic body in the float interacts with the magnetic body in the display color bar, causing it to flip. Red indicates liquid and white indicates no liquid, thereby achieving the purpose of accurately displaying the liquid level on site.

[0003] When measuring the liquid level in a container, a magnetic level gauge often encounters liquid entering the gauge too quickly, resulting in unstable pressure. Furthermore, there are many bubbles trapped in the liquid, which can impact the magnetic float inside the gauge, causing it to fluctuate and fluctuate significantly. This can lead to the gauge being unable to accurately display the liquid level in the container. To address this issue, we offer a self-balancing, low-density magnetic level gauge.

[0016] 1. When the liquid level gauge is in use, the liquid in the container can enter the working cylinder through the liquid inlet pipe. When the liquid passes through the pressure relief piece, the stirring blade can rotate with the liquid to stir the liquid evenly to relieve its internal pressure.

In this way, the liquid entering the working cylinder does not contain bubbles, which can prevent bubbles from impacting the magnetic float in the working cylinder, thereby ensuring the accuracy of the liquid level display.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1-6 As shown, the utility model provides a technical solution: a self-balancing low-density magnetic floating level gauge, comprising a working cylinder 1, the inner cavity of the working cylinder 1 is provided with a magnetic float 2, the magnetic float 2 has a low density and can float in the liquid, the lower part of the right side of the working cylinder 1 is penetrated by a liquid inlet pipe 4, and the upper part of the right side of the working cylinder 1 is penetrated by a liquid outlet pipe 5. When in use, the liquid level gauge can be installed on the outer wall of the container, the liquid inlet pipe 4 and the liquid outlet pipe 5 are connected to the inner cavity of the container, and the liquid in the container can enter the working cylinder 1 through the liquid inlet pipe 4.

[0028] Specifically, the pressure relief member 7 includes a rotating shaft 71, and the left and right sides of the rotating shaft 71 are respectively rotatably connected to the left and right sides of the inner wall of the liquid inlet pipe 4. The outer ring of the rotating shaft 71 is evenly provided with multiple arc-shaped stirring blades 72. The stirring blades 72 can rotate in the liquid inlet pipe 4 through the rotating shaft 71. When the liquid passes through the pressure relief member 7, the stirring blades 72 can rotate with the liquid to stir the liquid evenly, so as to relieve its internal pressure and keep it stable.

[0029] Furthermore, a plurality of "S"-shaped pressure-relief channels 81 are evenly provided on the back of the pressure-relief block 8, and a plurality of sharp teeth 82 are evenly provided on the inner circle of the pressure-relief channel 81. The liquid passing through the pressure-relief piece 7 will pass through the pressure-relief block 8. The plurality of "S"-shaped pressure-relief channels 81 can further relieve the internal pressure and keep it stable. At the same time, the sharp teeth 82 can puncture most of the bubbles in the liquid.

[0030] Furthermore, the pressure relief plate 9 is located at the liquid outlet of the liquid inlet pipe 4, and a plurality of through holes 91 are evenly arranged on the back of the pressure relief plate 9.

A plurality of scale lines 33 are evenly spaced on the left and right sides of the indicator groove 31. The liquid level values displayed by the scale lines 33 increase from top to bottom. After the liquid enters the working cylinder 1, the magnetic float 2 can float upward. At the same time, the magnetic float 2 floats upward and attracts the magnetic rotor 32 to flip upward. After flipping, the color difference is obvious. At this time, the value of the scale line 33 indicated by the red magnetic rotor 32 at the highest point is the liquid level in the container.

[0032] Among them, two fixing rings 10 are provided on the right side of the indicator plate 3 . The fixing rings 10 are fixedly sleeved on the outer ring of the working cylinder 1 , and the indicator plate 3 is fixed on the working cylinder 1 through the two fixing rings 10 .

The bottom of the working cylinder 1 and the top of the sewage pipe 6 are connected by two flanges 11, and the two flanges 11 are fixedly connected by multiple bolts and nuts. The two flanges 11 are respectively fixed to the bottom of the working cylinder 1 and the top of the sewage pipe 6. The two flanges 11 are fixed by multiple bolts and nuts, so that the working cylinder 1 and the sewage pipe 6 can be fixed together.

[0034] A drain valve 61 is provided on the right side of the drain pipe 6 . When cleaning the interior of the working cylinder 1 later, the drain valve 61 can be opened to discharge the residual liquid in the working cylinder 1 through the drain pipe 6 .
