Embodiment 1
[0084] (1) Basic type
[0085] A float type liquid level gauge displayed by a vernier, such as figure 1 and figure 2 As shown, it includes a float chamber 2 made of non-ferromagnetic material, a spherical float 1 made of ferromagnetic material in the float chamber 2, a scale 6 adjacent to the float chamber 2, a cylindrical guide rail 3, and a closed non-ferrous The cursor chamber 10 of magnetic transparent material, the scale 6, the axis of the cylindrical guide rail 3 and the axis of the cursor chamber 10 are parallel to each other and parallel to the axis of the float chamber 2, and the vernier 8 and the cylindrical guide rail 3 are respectively arranged on Inside the cursor chamber 10;
[0086] The cylindrical guide rail 3 is provided with a guide rail reinforcing rib plate 7 from top to bottom on the side close to the float chamber 2;
[0087] Wherein, described vernier 8 comprises magnetic steel 8-2, rectangular frame 8-5 and rolling system, and described rolling syst...
Embodiment 2
[0101] Another float type liquid level gauge displayed by the vernier, such as Figure 4 and Figure 5 As shown, it is different from the protective type of embodiment 1 in that the vernier guide rail is a rectangular parallelepiped guide rail 3'; correspondingly, the radial groove of the scroll wheel 8-4 is a rectangular groove 8-42 , the distance between the two inner parallel surfaces of the rectangular groove 8-42 is greater than the distance between the two outer surfaces corresponding to the guide rail 3'. Under the magnetic coupling effect of the magnetic steel 8-2 on the vernier 8 and the floating ball 1, the rolling wheel 8-4 rolls along the working surface of the cuboid guide rail 3'.
[0102] Further, in order to avoid the trouble of replacing the magnetic steel 8-2 after the magnetic steel 8-2 is demagnetized, the liquid level gauge is provided with a spare vernier 14 at the upper position in the vernier chamber 10, and correspondingly outside the vernier chamber ...
Embodiment 3
[0104] Another float-type liquid level gauge with a vernier display, on the basis of the aforementioned liquid level gauge, has improved its vernier 8, that is, the vernier 8 includes two sets of the rolling system, that is, includes two scroll wheels 8 -4, 8-4' and their respective shafts 8-3, 8-3' and rolling bearings 8-1, 8-1', such as Image 6 shown. The two sets of rolling systems are arranged in parallel up and down in the same rectangular frame 8-5, and the plane formed by the two shafts 8-3, 8-3' is perpendicular to the ground, so as to prevent the cursor 8 from The rotation around the axis is generated during the up and down movement, which improves the accuracy and reliability of use.
