Description

Technical Field

[0001] The utility model relates to the technical field of liquid level gauges, in particular to a high-temperature magnetic flap liquid level gauge. Background Art

[0002] High temperature magnetic flap level gauge is a device used to measure the liquid level in a high temperature environment. It is usually used in industrial processes, especially in situations where it is necessary to operate under high temperature conditions, such as chemical plants, petrochemicals, power stations, etc. The level gauge uses magnetic flap technology for liquid level control. It contains a magnetic flap or magnetic float that moves as the liquid level rises and falls.

[0003] However, the existing high-temperature magnetic flap level gauge has an integrated structural design. Since the high-temperature magnetic flap level gauge is used to monitor the liquid levels of different liquids, when the high-temperature magnetic flap level gauge monitors a specific liquid, it is necessary to regularly replace and repair the inside of the high-temperature magnetic flap level gauge to avoid long-term corrosion in the liquid level tube, which causes the magnetic float to be unable to move up and down normally.

[0004] However, the integrated structural design requires the use of chemical flushing to flush out internal impurities when cleaning the inside of the liquid level tube. However, the chemical flushing method still has the problem of cleaning dead corners. The integrated structural design makes it impossible to repair the high-temperature magnetic flap level gauge by directly replacing the liquid level tube when the liquid level tube cannot be cleaned. Directly replacing the high-temperature magnetic flap level gauge will increase the cost of use.

[0005] Therefore, the utility model proposes a high-temperature magnetic flap liquid level gauge. Utility Model Content

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a high-temperature magnetic flap level gauge, comprising a connecting elbow and a liquid level tube, wherein two connecting elbows are provided, and the two connecting elbows are respectively inserted at both ends of the liquid level tube, a magnetic float is provided in the liquid level tube, a magnetic flap assembly is provided on one side of the liquid level tube, a mounting assembly is provided on the side of the magnetic flap assembly close to the liquid level tube, and the magnetic flap assembly is arranged on the liquid level tube through the mounting assembly;

[0017] As a preferred implementation, a sliding groove is provided on one side of the scale plate close to the mounting assembly, and a scale groove is provided on the other side of the scale plate.

[0018] The beneficial effect of adopting the above-mentioned further scheme is that one side of the magnetic flap is red and the other side is white, and it is used in conjunction with the scale plate to detect the liquid level height in the detection object.

[0023] Compared with the prior art, the advantages and positive effects of the utility model are:

[0024] 1. In the utility model, the connecting elbow and the liquid level tube are designed as a split structure. The advantage of this design is that when cleaning the connecting elbow or the inside of the liquid level tube, the heat shrink sleeve is removed, and the connecting elbow and the liquid level tube are separated, and then the two components are cleaned separately to reduce the cleaning dead angle, and the split structure can also replace the liquid level tube that matches the height of the detected object according to the height of the detected object, thereby improving the detection range of the device, and under the action of the first annular groove and the second annular groove, when the connecting elbow and the liquid level tube are installed, the connection between the connecting elbow and the liquid level tube is sealed by a heating device, and when the heat shrink sleeve is melted, it is first filled into the first annular groove and the second annular groove, and under the action of the first annular groove and the second annular groove, the friction between the heat shrink sleeve and the connecting elbow and the liquid level tube is increased, so as to prevent the heat shrink sleeve from sliding up and down on the heat shrink sleeve and the liquid level tube after heat shrinkage;

Scale plates 22 are arranged on both sides of the flap frame 21. When in use, liquid enters the interior of the liquid level tube 12 and, under the action of buoyancy, drives the magnetic float 16 to float up as the liquid level rises. As the magnetic float 16 floats up, the magnetic flap 23 is flipped under the action of magnetic coupling.

[0049] A sliding groove 222 is provided on one side of the scale plate 22 close to the mounting assembly 3, and a scale groove 221 is provided on the other side of the scale plate 22.

[0052] Working principle:

[0053] like Figure 1 - Fig. 9 As shown, firstly, the heat shrink sleeve 11 is sleeved on the liquid level tube 12, and then the connecting elbow 1 is sleeved on both ends of the liquid level tube 12, and then the heat shrink sleeve 11 is moved to the connection between the connecting elbow 1 and the liquid level tube 12 respectively, and then the heat shrink sleeve 11 is heated by the heating mechanism to make the heat shrink sleeve 11 shrink. When the heat shrink sleeve 11 shrinks, it first fills into the first annular groove 14 or the second annular groove 15, and the connection is completed. The heat shrink sleeve 11 and the detection object are connected and fixed by the connecting flange 13. After the fixing is completed, the two installation components 3 are adjusted to the specified position according to the length of the liquid level tube 12, and then the installation plate 34 is turned over to the outer wall of the liquid level tube 12, and the two installation plates 34 are fixed by bolts. The mounting frame 31 is clamped and fixed between the liquid level tube 12, and the extruded rubber plate 33 is further driven to move to one side of the flap frame 21 by rotating the threaded rod 32, so that the extruded rubber plate 33 is clamped and fixed after contacting the surface wall of the flap frame 21, and the installation is completed. As the liquid level rises, the magnetic float 16 is driven to float up. As the magnetic float 16 floats up, the magnetic flap 23 is turned over under the action of the magnetic coupling, and is used in conjunction with the scale plate 22 to detect the liquid level height in the detection object. The liquid height inside the liquid level tube 12 can also be monitored in real time through the liquid level sensor 4. Further, under the action of the display screen 41, the signal collected by the liquid level sensor 4 is displayed, and the signal collected by the liquid level sensor 4 is sent to the user through the remote transmitter 42.
