Abstract
Description
Technical Field
[0001] This utility model relates to the field of magnetic level gauge technology, and in particular to a magnetic level gauge for ultra-low temperature applications. Background Technology
[0002] A magnetic level gauge is an instrument used to detect and display the liquid level in a container. It works by having a magnetic float move up and down with changes in the liquid level, causing a magnetic color block to flip and thus visually indicate the liquid level. Magnetic level gauges are suitable for industrial applications such as chemical and petroleum processing, and offer advantages such as simple structure, intuitive operation, reliability, and durability.
[0003] The existing technical solutions mentioned above have the following drawbacks: the existing magnetic level gauges do not have a low-temperature protection structure on the outside. When used in ultra-low temperature environments, the magnetic force of the magnetic level gauge will be affected, resulting in inaccurate readings. Utility Model Content
[0004] The purpose of this invention is to provide a magnetic float level gauge for ultra-low temperature applications.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A magnetic float level gauge for cryogenic applications includes a level gauge body. A first housing and a second housing are provided on the outer side of the level gauge body. A first connecting block is fixedly connected to the outer side of the first housing, and a first through hole is reserved on the outer side of the first connecting block. A second connecting block is fixedly connected to the outer side of the second housing, and a second through hole is reserved on the outer side of the second connecting block.
[0007] By adopting the above technical solution, two sets of housings are added to the outside of the level gauge. The housings are permeable with heat-insulating material, which can insulate the level gauge and prevent the magnetic flip plate from being affected by excessively low temperatures. At the same time, the overall structure is a docking installation form, and is tightened by bolts and nuts, which facilitates better assembly.
[0008] Furthermore, a magnetic flip plate component is provided on the outer side of the liquid level gauge body, a bolt is inserted into the first through hole, and the same bolt is inserted into the second through hole.
[0009] By adopting the above technical solution, the bolts and nuts are combined to facilitate the installation of the housing.
[0010] Furthermore, a nut is provided on the outside of the bolt, and a cavity is provided inside the first housing, with a first insulation layer and a second insulation layer provided inside the cavity.
[0011] By adopting the above technical solution, by adding insulation material, the first insulation layer wraps the inner side, and the second insulation layer is added inside the first insulation layer, which can further improve the insulation effect.
[0012] Furthermore, the first housing and the second housing are the same size and have the same specifications, and the first connecting block and the second connecting block are the same size and have the same specifications.
[0013] By adopting the above technical solution, the structure assembled with two sets of shells can be replaced at any time. It can be installed when needed and disassembled when not needed, making it convenient to use.
[0014] Furthermore, the bolt extends through the first connecting block and the second connecting block to the outside of the second connecting block, and the bolt and nut are threaded together.
[0015] By adopting the above technical solution and using bolts and nuts for connection, the assembly of the shells can be made more convenient.
[0016] In summary, the beneficial technical effects of this utility model are as follows:
[0017] The system employs a shell and an insulation layer. Two sets of shells are added to the outside for splicing and installation. After the shells are installed together, they are locked and fixed with bolts and nuts. The overall structure is easy to install and disassemble. At the same time, an insulation layer is added inside the shell. The insulation effect can be achieved by using two sets of different insulation materials, which effectively blocks low temperatures and prevents the magnetic effect of the magnetic flip plate from being affected in ultra-low temperature environments, ensuring that the equipment can be used normally and produce a stable working effect.

Detailed Implementation
[0023] The present invention will be further described in detail below with reference to the accompanying drawings.
[0024] Reference Figure 1-4 A magnetic level gauge for cryogenic applications includes a level gauge body 1. A first housing 3 and a second housing 4 are disposed on the outer side of the level gauge body 1. A first connecting block 5 is fixedly connected to the outer side of the first housing 3, and a first through hole 6 is reserved on the outer side of the first connecting block 5. A second connecting block 7 is fixedly connected to the outer side of the second housing 4, and a second through hole 8 is reserved on the outer side of the second connecting block 7. A magnetic level gauge component 2 is disposed on the outer side of the level gauge body 1. A bolt 9 is inserted into the first through hole 6, and a similar bolt 9 is inserted into the second through hole 8. A nut 10 is disposed on the outer side of the bolt 9. A cavity 11 is formed inside the first housing 3, and a first insulation layer 12 and a second... The second insulation layer 13 adds two sets of housings to the outside of the level gauge. The housings are permeable with insulation material, which can insulate the level gauge and prevent excessively low temperatures from affecting the magnetic flip plate. The overall structure is a butt-to-button installation form, which is locked by bolts 9 and nuts 10, making it easier to assemble. The bolts 9 and nuts 10 are combined to facilitate the installation between the housings. By adding insulation material, the first insulation layer 12 wraps the inner side, and the second insulation layer 13 is added inside the first insulation layer 12, which can further improve the insulation effect. The first insulation layer 12 uses polyurethane insulation board, and the second insulation layer 13 uses cement foam insulation board to improve the insulation effect.
[0025] like Figure 1-4 As shown, the first housing 3 and the second housing 4 are the same size and have the same specifications. The first connecting block 5 and the second connecting block 7 are the same size and have the same specifications. The bolt 9 passes through the first connecting block 5 and the second connecting block 7 and extends to the outside of the second connecting block 7. The bolt 9 and the nut 10 are threaded together.
[0026] The implementation principle of this embodiment is as follows: When the level gauge needs to be insulated, the first housing 3 and the second housing 4 can be installed on the outside of the level gauge. Then, the bolt 9 passes through the first connecting block 5 and the second connecting block 7, and is then locked by the nut 10. Then, the magnetic flip plate component 2 is fixed to the installed structure by the clamp. The insulation structure inside the housing is used to prevent low temperature from affecting the magnetic flip plate. When not used in an ultra-low temperature environment, the housing can be disassembled for easy access.
[0027] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
