Problems solved by technology
However, if the temperature of the ambient air changes, the transverse elastic coefficients of the torque tube 3 and the center shaft 4 change, and there is a problem that the torsion angle of the torque tube 3 and the like also changes even at the same liquid level L.

Embodiment Construction
[0037] for the manner in which the invention is carried out
[0038] based on Figure 1 to Figure 5 The illustrated embodiments illustrate the invention in detail. In addition, in Figure 1 ~ Figure 3 In , the magnifications of the drawings are shown differently.
[0039] figure 1 It is a cross-sectional view of the connection part from the displacer to the torque tube of the torque tube type liquid level gauge fixed on the top of the container. In the container T, for example, a high-temperature liquid for which the liquid level L should be measured is stored. The first casing 11 of the liquid level meter is fixed on the top of the container T through the flange 12, and the second casing described later is connected to the first casing 11, and the third casing is connected to the second casing. body, the flange 12 keeps the weight of the liquid level gauge, that is, the total weight including the first to third housings.

The present invention relates to a temperature compensation mechanism and a temperature compensation method for a torque tube type liquidometer, which can realize compensation, relative to the torsion force of the torque tube, a loading force for adjusting a spring, and a reversal loading force exerted towards a central shaft. A rotation substrate (30) is limited by the clamping portion (33) of a loading force adjusting mechanism (31) to rotate in a clockwise direction, spiral springs (34a, 34b) exert a torsion force in an anticlockwise direction through a loading force additional arm (29), and a loading force is exerted on a connection rod (25) connected with the central shaft in a direction opposite to the direction of the torsion force of the torque tube. The loading force is generated by the spiral springs (34a, 34b) through enabling a thread shaft (32) to rotate, moving the clamping portion (33) and adjusting the rotation stop position of spring hook portions (30b, 30c) by the rotation limiting portion (30a) of the rotation substrate (30).the mode of adjusting the rotation amount of the connection rod (35) connected with the central shaft and the torsion force of the torque tube to be balanced is performed based on the mode of enabling the detection angle of the connection rod (25) connected with the central shaft to be zero.
Description
technical field [0001] The invention relates to a temperature compensation mechanism and a temperature compensation method of a torque tube type liquid level gauge which is easily affected by temperature. Background technique [0002] Figure 6 It is a schematic diagram of the mechanism that generates twist in the torque tube of the torque tube type liquid level gauge. The torque tube 3 is twisted by the load of the displacer 1 when the liquid level is x% through the load transmission arm 2, as the twist angle (rad) of the torque tube 3 It is represented by the following (1) formula. [0003] [0004] A: Length of load transfer arm 2 (mm) [0005] d 1 : Outer diameter of torque tube 3 (mm) [0006] d 2 : inner diameter of torque tube 3 (mm) [0007] Lt: length of torque tube 3 (mm) [0008] Gt(T): Transverse elastic coefficient of torque tube 3 at temperature T (Kg / mm 2 ) [0009] F(x): The load of displacer 1 when the liquid level is x% (Kgf) [0010] In addit...
