Abstract
Description
Technical Field
[0001] The present application relates to the technical field of magnetic floating liquid level gauges, and more specifically, to a magnetic floating ball liquid level gauge. Background Art
[0002] The core of the magnetic level gauge, as an innovative level measurement device, is the ingenious use of magnetic floats as sensing elements. This design principle is based on the subtle magnetic interaction between the magnetic float and the magnetic body in the special display color strip, which intuitively and accurately maps the level or interface changes of the measured liquid, demonstrating a high degree of technical wisdom and measurement accuracy.
[0003] The liquid level gauges widely used in the current market mostly adopt an integrated structure, and the essence of its structure lies in the perfect nesting of two layers of precision metal tubes inside and outside. The two layers of tube walls are carefully evacuated, and then the vacuum port is sealed with exquisite welding technology to form an excellent heat-insulating cavity. This design not only effectively isolates the heat exchange between the liquid in the inner tube and the external environment, significantly improving the stability and accuracy of the measurement, but also acts as a solid protective barrier. Even if the inner tube is damaged in extreme cases, it can effectively prevent liquid leakage and ensure environmental safety.
[0004] However, the design and selection of the float of the traditional integrated level meter must be strictly customized according to the density and physical and chemical properties of the liquid to be measured. Although this ensures the accuracy of the measurement, it also invisibly limits its scope of application. Specifically, once the float is selected, the level meter is mainly suitable for measuring media with similar density and properties to the selected liquid. Although it can perform rough detection on media with slightly higher density but similar properties, the accuracy is inevitably compromised. In addition, the measurement conversion between different media requires frequent cleaning of the level meter to avoid mutual interference between the media, and the inherent characteristics of the integrated structure restrict the thoroughness of the cleaning to a certain extent, which in turn affects the versatility and accuracy of the measurement. Utility Model Content
[0005] Based on the above problems, the present application proposes a magnetic float ball liquid level gauge to solve the technical problems of low accuracy and poor versatility.
[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:
[0007] A magnetic float liquid level gauge comprises an upper cylinder, a lower cylinder installed below the upper cylinder, an upper opening and a vacuum opening of the liquid level gauge arranged on the upper cylinder, a lower opening and a drain opening of the liquid level gauge arranged on the lower cylinder, a solution arranged in the lower cylinder, and a magnetic float ball arranged in the solution.
[0008] In a specific feasible implementation, both the upper cylinder body and the lower cylinder body include an inner pipe wall and an outer pipe wall. A cavity is formed between the inner pipe wall and the outer pipe wall. The vacuum port is communicated with the cavity, the drain port is communicated with the solution, and the upper liquid level gauge port and the lower liquid level gauge port are respectively connected to the inner cavity of the inner pipe wall.
[0009] In a specific feasible implementation, the upper cylinder body and the lower cylinder body are connected by a flange. The flange includes an outer pipe sealing surface and an inner pipe sealing surface. There is an upper and lower cavity perforation between the outer pipe sealing surface and the inner pipe sealing surface, and bolts are provided on the flange.
[0010] In a specific feasible implementation, both the inner pipe sealing surface and the outer pipe sealing surface of the flange are TG surface seals.
[0011] In a specific feasible implementation, the inner pipe sealing surface and the outer pipe sealing surface are respectively adapted to each other between the inner pipe sealing surface and the outer pipe sealing surface.
[0012] Positive effects of the present utility model:
[0013] The traditional liquid level gauge is closely related to the characteristics of the liquid to be measured due to the design of the floating ball, which limits the measurement accuracy. The magnetic floating ball liquid level gauge of the present utility model improves the accuracy of liquid level detection by optimizing the magnetic interaction between the magnetic floating ball and the display system (although the display system is not described in detail in the original text, it can be assumed that it interacts with the magnetic body in the special display color bar). The magnetic floating ball moves precisely with the change of the liquid level and accurately reflects the liquid level through the change of magnetic force, thus improving the measurement accuracy.
[0014] The traditional liquid level gauge needs to customize the floating ball for specific liquids, which limits its application range. The magnetic floating ball liquid level gauge of the present utility model makes it easier to replace or adjust the magnetic floating ball through modular design, so that it can be applied to the measurement of liquids with different densities and properties, greatly enhancing the versatility of the liquid level gauge.
[0015] The magnetic floating ball liquid level gauge connects the upper cylinder body and the lower cylinder body through a detachable flange, making the cleaning process more convenient and thorough, avoiding the mutual interference between media, and improving the measurement stability and accuracy.

[0021] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0022] Embodiment 1
[0023] As Figure 1 shown, a magnetic floating ball 8 liquid level gauge includes an upper cylinder body 1, a lower cylinder body 2 installed below the upper cylinder body 1, an upper liquid level gauge port 3 and a vacuum port 4 provided on the upper cylinder body 1, a lower liquid level gauge port 5 and a drain port 6 provided on the lower cylinder body 2, a solution 7 provided in the lower cylinder body 2, and a magnetic floating ball 8 provided in the solution 7.
[0024] Through the magnetic interaction between the magnetic floating ball 8 and a possible external magnetic display element (such as a special display color bar), the liquid level gauge can accurately and intuitively reflect the liquid level change of the measured liquid. This magnetic induction method reduces mechanical contact and friction, and improves the stability and accuracy of measurement.
[0025] Both the upper cylinder body 1 and the lower cylinder body 2 include an inner pipe wall 9 and an outer pipe wall 10. A cavity 11 is formed between the inner pipe wall 9 and the outer pipe wall 10. The cavity 11 between the upper cylinder body 1 and the lower cylinder body 2 is vacuum-treated to form a good heat insulation and preservation layer. This effectively isolates the heat exchange between the inner pipe liquid and the external environment, reduces the influence of environmental temperature change on the measurement accuracy, and ensures the stability and accuracy of measurement.
[0026] The vacuum port 4 is communicated with the cavity 11, the drain port 6 is communicated with the solution 7, and the upper liquid level gauge port 3 and the lower liquid level gauge port 5 are respectively connected to the inner cavity of the inner pipe wall 9.
[0027] The settings of the vacuum port 4 and the drain port 6 make it easy to clean the cavity 11. At the same time, the design of the upper liquid level gauge port 3 and the lower liquid level gauge port 5 makes it more convenient to replace or clean the liquid in the inner tube. This maintainability improves the service life of the equipment and the reliability of measurement.
[0028] Embodiment 2
[0029] A magnetic float ball 8 liquid level gauge, comprising an upper cylinder body 1, a lower cylinder body 2 installed below the upper cylinder body 1, a liquid level gauge upper port 3 and a vacuum port 4 provided on the upper cylinder body 1, a liquid level gauge lower port 5 and a drain port 6 provided on the lower cylinder body 2, a solution 7 provided in the lower cylinder body 2, and a magnetic float ball 8 provided in the solution 7. The magnetic float ball 8 is made of a corrosion-resistant material, and a polytetrafluoroethylene layer is deposited on the outside, which improves the corrosion resistance of the float. The polytetrafluoroethylene layer reduces the friction between the magnetic float ball and the metal wall.
[0030] Both the upper cylinder body 1 and the lower cylinder body 2 include an inner pipe wall 9 and an outer pipe wall 10. A cavity 11 is formed between the inner pipe wall 9 and the outer pipe wall 10. The vacuum port 4 and the drain port 6 communicate with the cavity 11, and the liquid level gauge upper port 3 and the liquid level gauge lower port 5 are respectively connected to the inner cavity of the inner pipe wall 9.
[0031] The upper cylinder body 1 and the lower cylinder body 2 are connected by the flange 12. The flange 12 includes an outer pipe sealing surface 13 and an inner pipe sealing surface 14. An upper and lower cavity perforation 15 is provided between the outer pipe sealing surface 13 and the inner pipe sealing surface 14, and bolts 16 are provided on the flange 12. Although the design of the magnetic float ball 8 still needs to consider the characteristics of the measured liquid, the overall structural design of the liquid level gauge makes it relatively easy to replace the magnetic float ball 8. This means that the magnetic float ball 8 can be quickly adjusted or replaced according to different measurement requirements to adapt to the measurement of different types and properties of liquids, improving the versatility and flexibility of the equipment.
[0032] The inner pipe sealing surface 14 and the outer pipe sealing surface 13 are respectively adapted to each other between the inner pipe sealing surface 14 and the outer pipe sealing surface 13.
[0033] The inner pipe sealing surface 14 and the outer pipe sealing surface 13 of the flange 12 are both TG surface seals. The TG surface seal consists of two parts: a tenon and a groove. This design can stably fix the gasket and prevent it from moving or deforming under pressure. The gasket is placed in the groove, which can effectively reduce the possibility of the gasket being impacted by pressure, thereby improving the sealing effect. Since the gasket is stably fixed in the groove, the TG surface seal can provide a good sealing effect, especially suitable for occasions with high sealing requirements. Since the gasket can be designed to be narrower, the force of the bolt 16 required to compress the gasket is also correspondingly smaller. Even in a high-pressure environment, the size of the bolt 16 does not have to be too large.
[0034] The principle of the embodiment of this application is as follows: For the liquid to be measured with different densities and properties, a liquid level gauge in this application is manufactured and equipped with magnetic floating balls 8 of different densities; during use, the magnetic floating balls 8 can be replaced according to the liquid density. Open the vacuum port 4. After the cavity 11 has the same pressure as the outside, remove the flange 12, clean the liquid level gauge and then replace the target magnetic floating ball 8, and then assemble the liquid level gauge. Use the vacuum port 4 at the top to evacuate, close the vacuum port 4, and then wrap the outside of the flange 12 with heat insulation materials, which improves the universality and accuracy of the liquid level gauge, is convenient to operate, and reduces the replacement cost of the equipment.
[0035] Finally, it should also be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of another identical element in the process, method, article or device including the said element.
