Description

Technical Field

[0001] This utility model relates to the field of liquid level gauge float technology, specifically a spherical float for a high-pressure liquid level gauge. Background Technology

[0002] In modern chemical, petroleum refining, natural gas storage and transportation, and new energy storage industries, high-pressure vessels are widely used in key processes such as reaction, storage, and transportation. Accurate measurement of the liquid level inside the vessel has become a core requirement to ensure production safety and efficiency. As a key device for acquiring liquid level data, the performance of the spherical float, the core component of the high-pressure liquid level gauge, directly determines the accuracy of liquid level measurement, the stability of equipment operation, and even the safety and reliability of the entire industrial process.

[0003] Currently, most of the spherical floats of high-pressure level gauges on the market are made using integral casting or simple splicing assembly. Although the integrally cast float has a relatively integrated structure, during the casting process, due to uneven cooling and shrinkage of the metal, defects such as air holes and shrinkage porosity are easily formed inside. These defects will become sources of stress concentration under high pressure. On the other hand, for floats with simple splicing structures, the connection points between the components often become weak points in mechanical performance. When faced with the pressure of high-pressure media, leakage is very likely to occur at the splicing gaps, and even breakage may occur when the pressure fluctuates.

[0004] From a mechanical perspective, existing floats lack precise consideration of pressure distribution under high-pressure environments during their design. The pressure of the medium inside a high-pressure container is not only high in value, but also dynamically changes with factors such as liquid level, temperature, and medium flow, resulting in a complex three-dimensional pressure distribution on the float. However, the simple internal support structure of traditional floats allows local areas of the float to bear excessive pressure for a long time, accelerating material fatigue and damage. Once the float breaks under high pressure, the consequences will be very serious. Failure of liquid level measurement will prevent operators from accurately grasping the amount of medium in the container, affecting production scheduling and process control. Utility Model Content

[0005] The purpose of this utility model is to provide a spherical float for a high-pressure liquid level gauge, in order to solve the problem mentioned in the background art that the existing spherical floats for high-pressure liquid level gauges are prone to breakage under high pressure due to casting defects, weak splicing structure and unreasonable mechanical design, which leads to liquid level measurement failure and affects production safety and scheduling control.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a spherical float for a high-pressure liquid level gauge, comprising an upper shell, a middle shell fixedly disposed at the lower end of the upper shell, and a lower shell fixedly disposed at the lower end of the middle shell, wherein the upper shell, middle shell, and lower shell are designed as two separate halves, and the connection between the two halves of the upper shell, middle shell, and lower shell is welded to form a weld ring, a connecting block is fixedly disposed at the upper end of the upper shell, and an external connecting post is fixedly connected to the upper end of the connecting block, and the upper end of the external connecting post is connected to the sensing component of the high-pressure liquid level gauge;

[0007] The lower end of the connecting block is fixedly connected to an inner support column, and the inner surfaces of the upper shell, middle shell and lower shell are fixedly provided with inner support rings, and the upper and lower surfaces of adjacent inner support rings are fixedly connected with reinforcing ribs, and the inner surface of the inner support ring is fixedly provided with a separator membrane.

[0008] A support frame is fixedly installed on the lower outer surface of the inner support column.

[0009] Preferably, the maximum outer diameter of the upper shell, middle shell, and lower shell decreases sequentially from top to bottom, and the connection points of each pair of the upper shell, middle shell, and lower shell are all recessed.

[0010] By adopting the above technical solution, the resistance encountered by the float when it moves in the liquid can be effectively reduced. This is because the shape structure makes the liquid flow more smoothly when it passes through the float and is less likely to generate large turbulence. At the same time, it reduces the impact of the liquid flow on the float, allowing the float to float more stably with the changes in liquid level, thereby improving the accuracy and stability of liquid level measurement.

[0011] Preferably, the longitudinal section of the inner support ring is C-shaped, and the inner support ring is hollow. The C-shaped opening of the inner support ring is engaged with the connection points of the upper shell, the middle shell, and the lower shell.

[0012] By adopting the above technical solution, the C-shaped inner support ring is snapped into place at the connection with the shell, which can enhance the internal structural stability of the float and provide more reliable support for the float. The hollow design, while ensuring that the inner support ring has a certain structural strength, reduces the overall weight of the float, which helps to improve the sensitivity of the float to changes in liquid level and enables it to respond to changes in liquid level more quickly.

[0013] Preferably, the inner diameter of the inner support ring decreases sequentially from top to bottom, and the reinforcing ribs are arranged at equal angles between two adjacent inner support rings, and the reinforcing ribs are inclined.

[0014] The above technical solution, with the inner diameter of the inner support ring decreasing from top to bottom, is compatible with the overall shape of the float, which is larger at the top and smaller at the bottom. This better adapts to the characteristic that the pressure inside the container increases with depth under high pressure, enhances the pressure resistance of different parts of the float, and the reinforcing ribs set at equal angles further strengthen the connection between adjacent inner support rings, distributing the pressure borne by the inner support rings more evenly and improving the overall pressure resistance of the float.

[0015] Preferably, the support frames are distributed at equal angles on the outer surface of the inner support column, the support frames on the upper and lower sides of the separator are staggered, one end of the support frame is in contact with the outer surface of the separator, and the end of the support frame in contact with the separator is designed as a disc.

[0016] By adopting the above technical solution, the equally angled support frame can evenly support the separator membrane, ensuring that the separator membrane is subjected to balanced force. The staggered support frames on the upper and lower sides fit tightly with the separator membrane. The disc-shaped design increases the contact area, which can better disperse the pressure and prevent the separator membrane from being damaged due to excessive local pressure. At the same time, this structure further enhances the stability of the float's internal structure and rationally divides the internal space of the float. When the float leaks locally, the separator membrane can effectively prevent the float from completely failing and improve the overall performance of the float.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the spherical float of the high-pressure liquid level gauge:

[0018] 1. The upper, middle, and lower shells adopt a two-part split design and are welded together to form a weld ring. This structural design facilitates manufacturing and ensures a tight connection between the shells, effectively improving the overall sealing of the float and preventing liquid from seeping into the float under high pressure, thus ensuring the normal operation of the float. At the same time, the inner support column at the lower end of the connecting block, the inner support rings on the inner sides of the upper, middle, and lower shells, and the reinforcing ribs work together, and the snap-fit ​​installation of the inner support rings at the connection points with the shells forms a stable internal support structure, which greatly enhances the float's pressure resistance, making it less prone to deformation in high-pressure environments and extending the float's service life.

[0019] 2. The maximum outer diameter of the upper, middle, and lower shells decreases sequentially from top to bottom, and the connection points are concave. This structural design effectively reduces the resistance of the float when moving in the liquid, reduces the impact of liquid flow on the float, and allows the float to float more stably with changes in liquid level, thereby improving the accuracy and stability of liquid level measurement. At the same time, the inner support ring adopts a C-shaped and hollow design, which reduces the overall weight of the float while ensuring structural strength, and helps to improve the sensitivity of the float. The setting of the separator membrane and support frame not only further enhances the stability of the internal structure of the float, but also reasonably divides the internal space of the float, preventing the float from completely failing due to leakage to a certain extent. Meanwhile, the support frames on the upper and lower sides of the separator membrane are staggered and fit tightly with the separator membrane, which can better distribute pressure and improve the overall performance of the float.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-6This utility model provides a technical solution: a spherical float for a high-pressure liquid level gauge.

[0029] Example 1: This example discloses: an upper housing 1, a middle housing 2 fixedly disposed at the lower end of the upper housing 1, and a lower housing 3 fixedly disposed at the lower end of the middle housing 2. The upper housing 1, the middle housing 2, and the lower housing 3 are designed as two separate parts, and the connection between the two parts of the upper housing 1, the middle housing 2, and the lower housing 3 is welded to form a weld ring 4. A connecting block 5 is fixedly disposed at the upper end of the upper housing 1, and an external connecting post 6 is fixedly connected to the upper end of the connecting block 5. The upper end of the external connecting post 6 is connected to the sensing component of the high-pressure liquid level gauge.

[0030] The upper shell 1, middle shell 2, and lower shell 3 adopt a two-part split design and are welded to form a weld ring 4. This structure first ensures the sealing of the float. Under high pressure, the tightly welded weld ring 4 effectively prevents liquid from seeping into the interior of the float, ensuring the normal operation of the float. When the liquid level in the high-pressure container changes, the float will float up and down accordingly. The external connecting post 6 fixed by the upper connecting block 5 of the upper shell 1 is connected to the sensing component of the high-pressure liquid level gauge. The up and down movement of the float drives the external connecting post 6 to move, transmitting the liquid level change information to the sensing component, thereby realizing the measurement of the liquid level.

[0031] Example 2: This example is based on Example 1: The lower end of the connecting block 5 is fixedly connected to an inner support column 7, and the inner surfaces of the upper shell 1, the middle shell 2 and the lower shell 3 are fixedly provided with inner support rings 8, and the upper and lower surfaces of adjacent inner support rings 8 are fixedly connected with reinforcing ribs 9, and the inner surface of the inner support rings 8 is fixedly provided with a separator membrane 10.

[0032] A support frame 11 is fixedly installed on the lower outer surface of the inner support column 7;

[0033] The maximum outer diameter of the upper shell 1, the middle shell 2 and the lower shell 3 decreases sequentially from top to bottom, and the connection points of the upper shell 1, the middle shell 2 and the lower shell 3 are all concave.

[0034] The longitudinal section of the inner support ring 8 is C-shaped, and the inner support ring 8 is hollow. The C-shaped opening of the inner support ring 8 is engaged with the connection points of the upper shell 1, the middle shell 2 and the lower shell 3.

[0035] The inner diameter of the inner support ring 8 decreases from top to bottom, and the reinforcing ribs 9 are set at equal angles between two adjacent inner support rings 8, and the reinforcing ribs 9 are set at an inclination.

[0036] The support frames 11 are evenly distributed on the outer surface of the inner support column 7. The support frames 11 on the upper and lower sides of the separator 10 are staggered, and one end of the support frame 11 is attached to the outer surface of the separator 10. The end of the support frame 11 that is attached to the separator 10 is designed as a disc.

[0037] The inner support column 7 at the lower end of the connecting block 5, the inner support ring 8 on the inner side of the shell, and the reinforcing rib 9 work together to form a stable internal support structure. The C-shaped opening of the inner support ring 8 engages with the connection of the shell, enhancing the float's pressure resistance and making it less prone to deformation under high pressure. The maximum outer diameter of the upper shell 1, middle shell 2, and lower shell 3 decreases sequentially from top to bottom, and the design of the connection is concave, reducing the resistance of the float's movement in the liquid and reducing the impact of liquid flow, allowing the float to float more stably with changes in liquid level. The hollow design of the inner support ring 8 reduces the weight of the float and improves sensitivity. The separator 10 and the support frame 11 not only enhance the stability of the internal structure but also rationally divide the internal space. When a local leakage occurs, the separator 10 can prevent the float from completely failing. Furthermore, the support frame 11, which is staggered on the upper and lower sides of the separator 10, fits tightly against the separator 10, better dispersing pressure, improving the overall performance of the float, and ensuring the accuracy and stability of liquid level measurement.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
