In the torque flowmeter, the rotating shaft 6 is installed in the pipeline 4, the eccentric valve disc 3 is eccentrically installed on the rotating shaft 6, and when fluid passes through the eccentric valve disc 3, the fluid pushes the eccentric valve disc 3 to rotate for a certain angle so as to reduce resistance loss of fluid flow; meanwhile, an angle sensor 2 and a torque sensor 5 are further mounted on the rotating shaft 6, the angle sensor 2 and the torque sensor 5 are connected with a processing circuit, the angle sensor 2 and the torque sensor 5 send detected angle information and torque information to the processing circuit, the processing circuit is in data communication with an external man-machine interface or other equipment, and the external device analyzes the angle information and the torque information to obtain the measured flow. In addition, when the eccentric valve disc 3 rotates under the action of fluid, the rotating shaft 6 rotates by a certain angle under the driving of the eccentric valve disc 3, at the moment, the torsion spring 1 is compressed until the torque generated by the eccentric valve disc 3 on the rotating shaft 6 is equal to the torque generated by the torsion spring 1 on the eccentricity, and the system is in a balanced state. This can further improve the accuracy of the angle information and the torque information measured by the angle sensor 2 and the torque sensor 5.
It should be noted that, in order to ensure the stability of flow measurement, a multi-gear limiting device may be disposed inside the angle sensor 2.
As an alternative, referring to fig. 2, the rotating shaft 6 includes a first shaft body 61 and a second shaft body 63, the first shaft body 61 is used for mounting the eccentric valve disc 3 and the torque sensor 5, and the second shaft body 63 is used for mounting the torsion spring 1; the first shaft 61 is provided with a first gear 62, the second shaft 63 is provided with a second gear 64, and the first gear 62 is engaged with the second gear 64. Adopt foretell mode, when fluid process eccentric valve disc 3, eccentric valve disc 3 drives first axis body 61 and rotates, and then set up first gear 62 on first axis body 61 and rotate along with the rotation of first axis body 61, because of first gear 62 and the meshing of second gear 64, and then second gear 64 can rotate certain angle at first gear 62's effect to make second axis body 63 rotate along with the rotation of eccentric valve disc 3, at this moment, torsional spring 1 is compressed, until the moment of torsion that eccentric valve disc 3 produced to pivot 6 with the moment of torsion that torsional spring 1 produced to the eccentricity equals, the system is in balanced state, so that the measured value of the torque sensor 5 of installing on first axis body 61 is more accurate.
It should be noted that the transmission ratio between the first gear 62 and the second gear 64 is adjusted according to the specific use situation, and further, the standards of the number of teeth, the tooth distance, the size and the like of the first gear 62 and the second gear 64 are defined according to the specific situation.
