DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figures 1 - 3, the present utility model provides the following technical solutions: A floating ball type liquid level transmitter, comprising a liquid level transmitter main body 1, a measuring conduit 2 fixed to the bottom end of the liquid level transmitter main body 1, a magnetic floating ball 3 slidably sleeved on the measuring conduit 2, a mounting flange 4 fixed to the top end of the measuring conduit 2, and two limiting sleeves 5 fixedly spaced on the measuring conduit 2. The magnetic floating ball 3 moves within the inner space between the two limiting sleeves 5. A limiting ring 21 is fixed on the measuring conduit 2. The mounting flange 4 includes: a first half flange 41, a second half flange 42, a positioning insert block 422, and a locking member 43.

[0032] Further, as shown by Figure 1 and Figure 2 , in this embodiment, the first half flange 41 has a first limiting groove 411 for the limiting ring 21 to be inserted into, and the first half flange 41 also has two symmetrically distributed positioning grooves 412. The second half flange 42 has a second limiting groove 421 for the limiting ring 21 to be inserted into. The two positioning insert blocks 422 are symmetrically fixed on the second half flange 42 and inserted into the positioning grooves 412. After the positioning insert blocks 422 are inserted into the positioning grooves 412, the locking member 43 is used for locking. After adopting the above scheme, during use, first, according to the actual installation scenario, select a suitable mounting flange 4 and fix it on the measuring conduit 2. It is possible to install the first half flange 41 first, or install the second half flange 42 first, or install the first half flange 41 and the second half flange 42 simultaneously. Taking the simultaneous installation of the first half flange 41 and the second half flange 42 as an example, make the first limiting groove 411 and the second limiting groove 421 correspond to the limiting ring 21 simultaneously, and butt the first half flange 41 and the second half flange 42 and sleeve them on the measuring conduit 2. At this time, the limiting ring 21 is inserted into the first limiting groove 411 and the second limiting groove 421, and the positioning insert blocks 422 are inserted into the positioning grooves 412. Finally, use the locking member 43 for locking to ensure the stability after the butt joint of the first half flange 41 and the second half flange 42. The limiting ring 21 is used to limit the position of the mounting flange 4 to ensure the stability of the mounting flange 4. The mounting flange 4 of the present utility model can be independently installed and disassembled, which is convenient to replace mounting flanges 4 of different specifications according to different installation scenarios, making the use more reliable, and it is also convenient to disassemble and replace the damaged mounting flange 4, reducing the maintenance cost and maintenance difficulty.

[0033] Optionally, as shown by Figure 1 and Figure 2 , in this embodiment, the locking member 43 is a hexagon head bolt. The first half flange 41 has a first internal thread hole 4121 that cooperates with the locking member 43. Therefore, after the positioning insert blocks 422 are inserted into the positioning grooves 412, the locking member 43 is screwed into the first internal thread hole 4121. After the locking member 43 is tightened, the locking member 43 abuts against the positioning insert blocks 422 to ensure the stability after the butt joint of the first half flange 41 and the second half flange 42.

[0034] Preferably, as shown by Figure 1 and Figure 2 In this embodiment, there is a locking groove 4221 on the positioning insert block 422 for the locking member 43 to be embedded. Therefore, after the locking member 43 is tightened, the locking member 43 is embedded into the locking groove 4221 for further locking, which further improves the stability after the docking of the first half flange 41 and the second half flange 42.

[0035] Preferably, as shown by Figure 1 and Figure 2 In this embodiment, the outer wall of the limiting ring 21 abuts against the inner walls of the first limiting groove 411 and the second limiting groove 421, ensuring the stability of the mounting flange 4 mounted on the measuring conduit 2 and avoiding jitter. Therefore, the liquid level transmitter main body 1 is prevented from jittering during operation.

[0036] Preferably, as shown by Figure 1 and Figure 3 In this embodiment, it further includes: a rubber lining ring 6. There is a mounting card slot 51 on the inner wall of the limiting sleeve 5. The rubber lining ring 6 is located in the mounting card slot 51, and the inner wall of the rubber lining ring 6 abuts against the outer wall of the measuring conduit 2. The rubber lining ring 6 has flexibility. Therefore, there is friction between the rubber lining ring 6 and the outer wall of the measuring conduit 2, which can ensure the stability of the limiting sleeve 5. When adjusting the height of the limiting sleeve 5, the limiting sleeve 5 can be directly moved, which is convenient for adjustment. And relying on the friction can ensure the stability of the limiting sleeve 5 after adjustment without changing the original structure of the measuring conduit 2.

[0037] Preferably, as shown by Figure 1 and Figure 3 In this embodiment, the outer wall of the rubber lining ring 6 abuts against the inner wall of the mounting card slot 51, ensuring the stability of the rubber lining ring 6 and also ensuring the stability of the limiting sleeve 5 and preventing the limiting sleeve 5 from jittering.

[0038] Preferably, as shown by Figure 1 and Figure 3 In this embodiment, it further includes: anti-slip convex rings 61. A plurality of anti-slip convex rings 61 are fixedly arranged at equal intervals on the inner wall of the rubber lining ring 6, and the anti-slip convex rings 61 extend out of the mounting card slot 51. By providing the anti-slip convex rings 61, the friction between the rubber lining ring 6 and the outer wall of the measuring conduit 2 is further increased, and the stability of the limiting sleeve 5 is further improved.

[0039] Preferably, as shown by Figure 1 and Figure 3As shown, in this embodiment, a second internal thread hole 52 is machined on the limit sleeve 5. When necessary, a bolt can be screwed into the second internal thread hole 52, and the bolt abuts against the rubber lining ring 6, and then the rubber lining ring 6 is used to squeeze the measuring conduit 2, further improving the stability of the limit sleeve 5. Moreover, the bolt does not directly contact the measuring conduit 2, avoiding scratching the measuring conduit 2 by the bolt.

[0040] The circuit connection involved in the present utility model is a conventional means adopted by those skilled in the art, and technical inspiration can be obtained through a limited number of tests, belonging to the widely used prior art.

[0041] The components not described in detail herein are prior art.

[0042] The working principle and usage process of the present utility model: For the liquid level transmitter main body 1 of the present utility model, during use, first select a suitable mounting flange 4 according to the actual installation scenario and fix it on the measuring conduit 2, so that the first limit groove 411 and the second limit groove 421 correspond to the limit ring 21 at the same time, and butt the first half flange 41 and the second half flange 42 and sleeved on the measuring conduit 2. At this time, the limit ring 21 is embedded in the first limit groove 411 and the second limit groove 421, and the positioning plug 422 is embedded in the positioning groove 412. Finally, use the locking member 43 for locking to ensure the stability after the first half flange 41 and the second half flange 42 are butted. The limit ring 21 is used to limit the position of the mounting flange 4 to ensure the stability of the mounting flange 4. After the mounting flange 4 is installed, the liquid level transmitter main body 1 can be fixedly installed by using the mounting flange 4;

[0043] The mounting flange 4 of the present utility model can be independently installed and disassembled, which is convenient to replace mounting flanges 4 of different specifications according to different installation scenarios, making the use more reliable. For the damaged mounting flange 4, it is also convenient to disassemble and replace, reducing the maintenance cost and maintenance difficulty.
