Description

Technical Field

[0001] This utility model relates to a level indicating device for a magnetic float level gauge, belonging to the field of level gauges. Background Technology

[0002] A magnetic float level gauge is a liquid level measuring device based on the principle of magnetic coupling. A magnetic float is placed inside the measuring cylinder, moving up and down with the rise and fall of the measured liquid level. A permanent magnet is embedded inside the float, and its magnetic field strength is sufficient to penetrate the measuring cylinder wall, creating magnetic coupling with the external float assembly. When the float rises, the float's magnetic field causes the small magnet on the float to rotate, causing the float's color to flip (e.g., from white to red); when the float falls, the float flips in the opposite direction. The color boundary line represents the current liquid level height; typically, red indicates a liquid area, and white indicates a liquid-free area. If the coating on the float surface is exposed to sunlight for a long time, its pigment molecules will undergo photodegradation due to ultraviolet radiation, causing the coating color to gradually fade; for example, the originally bright red will become noticeably lighter. This phenomenon reduces the color contrast of the float's liquid level indication color, making it difficult for operators to clearly and quickly distinguish the boundary between liquid-free and liquid-free areas, which may affect the accurate judgment of the liquid level status. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a liquid level indicating device for a magnetic float level gauge to solve the problems mentioned in the background art. This utility model realizes the light-shielding treatment of the magnetic float to prevent the magnetic float from being exposed to sunlight for a long time.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a level indicating device for a magnetic float level gauge, comprising a measuring cylinder, a magnetic float mounted on the outer surface of the measuring cylinder, a gas phase interface mounted on the upper end of the measuring cylinder, and a liquid phase interface mounted on the lower end of the measuring cylinder. Flanges are mounted on both the gas phase interface and the liquid phase interface, both away from the measuring cylinder. A first light-blocking plate and a second light-blocking plate are respectively provided on both sides of the magnetic float along its width direction. Two connecting brackets are mounted on the side of the first light-blocking plate facing away from the second light-blocking plate and the side of the second light-blocking plate facing away from the first light-blocking plate. An arc-shaped plate that fits against the flange is mounted on the end of the connecting bracket near the flange. Two small holes for inserting bolts are provided on the arc-shaped plate, aligned with the holes on the flange. A movable plate is hinged to the end of the first light-blocking plate away from the flange. The end of the movable plate away from the first light-blocking plate is connected to the second light-blocking plate via a limiting member.

[0005] Furthermore, the limiting member includes an L-shaped plate, an L-shaped plate is installed on the side of the second wind deflector away from the flange, the L-shaped plate and one side of the second wind deflector form an upward-opening space, a limiting plate is inserted between the L-shaped plate and the second wind deflector, and one end of the limiting plate is rotatably connected to the movable plate.

[0006] Furthermore, an upper ear plate is installed at the upper end of the movable plate, and a lower ear plate is installed at the lower end of the movable plate.

[0007] Furthermore, the lower end of the measuring cylinder is open, and a connecting ring for installing a drain valve is installed at the lower end of the measuring cylinder. One side of the connecting ring has multiple circular holes at equal intervals for inserting bolts.

[0008] Furthermore, the measuring cylinder is fitted with a plurality of U-shaped rods arranged at equal intervals, and the two ends of the U-shaped rods are respectively installed on two parallel sides of the magnetic flip plate by screws.

[0009] Furthermore, the liquid phase interface and the gas phase interface are arranged in parallel to each other, and the liquid phase interface, the gas phase interface and the measuring cylinder are arranged perpendicular to each other.

[0010] Furthermore, the connecting frame has a U-shaped structure, and the connecting frame and the arc-shaped plate are integrally formed.

[0011] The beneficial effects of this utility model are:

[0012] 1. A first light-blocking plate and a second light-blocking plate are set on both sides of the magnetic flip plate. The first light-blocking plate, the second light-blocking plate and the movable plate form a three-dimensional light-blocking structure to block sunlight from shining directly on the surface of the magnetic flip plate, reduce the photodegradation effect of ultraviolet rays on the coating, significantly slow down the color fading rate, maintain the high contrast of the red / white interface, and ensure that the liquid level indication is clear and easy to identify.

[0013] 2. The first and second light-blocking plates are connected to the flange bolts of the measuring cylinder via a connecting frame and an arc plate. No additional drilling or damage to the original structure is required. The mounting holes of the level gauge flange can be used directly, reducing the amount of bolts used.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-3 This utility model provides a technical solution: a level indicating device for a magnetic float level gauge, including a measuring cylinder 1, the lower end of the measuring cylinder 1 being open, and a connecting ring 14 for installing a drain valve installed at the lower end of the measuring cylinder 1. One side of the connecting ring 14 is annularly and equidistantly provided with multiple circular holes for inserting bolts. A magnetic float 15 is installed on the outer surface of the measuring cylinder 1, wherein multiple U-shaped rods 12 are sleeved on the measuring cylinder 1 and arranged at equal intervals, so that the two ends of the U-shaped rods 12 are respectively installed on two parallel sides of the magnetic float 15 by screws, thereby completing a stable connection between the magnetic float 15 and the measuring cylinder 1. A gas phase interface 2 is installed at the upper end of the measuring cylinder 1, and a liquid phase interface 13 is installed at the lower end of the measuring cylinder 1. The liquid phase interface 13 and the gas phase interface 2 are arranged parallel to each other, and the liquid phase interface 13 and the gas phase interface 2 are arranged perpendicular to each other. A flange 3 is installed at the end of the gas phase interface 2 away from the measuring cylinder 1 and the end of the liquid phase interface 13 away from the measuring cylinder 1. The design of the flange 3 facilitates the connection of the liquid phase interface 13 and the gas phase interface 2 to the corresponding interfaces on the container using bolts.

[0022] See Figures 1-4The magnetic flip plate 15 has a first light-blocking plate 6 and a second light-blocking plate 10 on both sides along its width. Two connecting brackets 5 are installed on the side of the first light-blocking plate 6 facing away from the second light-blocking plate 10 and the side of the second light-blocking plate 10 facing away from the first light-blocking plate 6. The connecting bracket 5 has a U-shaped structure. An arc-shaped plate 4, which fits snugly against the flange 3, is installed at the end of the connecting bracket 5 closest to the flange 3. The connecting bracket 5 and the arc-shaped plate 4 are integrally formed. Two small holes 16, aligned with the holes on the flange 3, are provided on the arc-shaped plate 4 for inserting bolts. The first light-blocking plate 6 and the second light-blocking plate 10 are bolted to the corresponding flange 3 using the connecting brackets 5 and the arc-shaped plate 4. This design eliminates the need for additional drilling or damage to the original structure, directly utilizing the existing mounting holes on the level gauge flange 3. This ensures a stable connection while reducing the number of bolts used. This installation method not only simplifies the operation process but also reduces the impact on the original equipment structure, improving the convenience and economy of installation.

[0023] See Figures 1-4 A movable plate 7 is hinged to the end of the first light-blocking plate 6 away from the flange 3. An L-shaped plate 8 is installed on the side of the second light-blocking plate 10 away from the flange 3. The L-shaped plate 8 and the side of the second light-blocking plate 10 form an upward-opening space. A limiting plate 9 is inserted between the L-shaped plate 8 and the second light-blocking plate 10. One end of the limiting plate 9 is rotatably connected to the movable plate 7. The limiting plate 9 and the L-shaped plate 8 cooperate with each other to limit the position of the movable plate 7. After the limiting plate 9 is separated from the L-shaped plate 8, it is easy to view the magnetic flip plate 15. An upper ear plate 11 is installed at the upper end of the movable plate 7, and a lower ear plate 17 is installed at the lower end of the movable plate 7. When the movable plate 7 is in the closed state, the upper ear plate 11 and the lower ear plate 17 are respectively located on the upper and lower sides of the magnetic flip plate 15, thereby improving the light-blocking effect. The first light-blocking plate 6 and the second light-blocking plate 10 are respectively set on both sides of the magnetic flip plate 15 and connected by the movable plate 7 to form a three-dimensional light-blocking structure. This structure effectively blocks direct sunlight from reaching the surface of the magnetic flip plate 15, thereby reducing the photodegradation reaction of the coating caused by ultraviolet rays, significantly slowing down the color fading rate, and ensuring that the red / white interface always maintains high contrast, thus ensuring that the liquid level indication is clear and identifiable.
