Description

Anti-blocking metal float flowmeter

Technical Field

The utility model relates to the technical field of metal float flowmeters, in particular to an anti-blocking metal float flowmeter.

Background

Metal tube float flowmeters are variable area flowmeters, i.e., in the vertical measurement tube of a flowmeter, when fluid flows up the tube. The float moves upwards, and the lifting force borne by the float and the gravity of the float reach balance at a certain position, so that the circulation annular space area between the float and the pore plate (or the taper pipe) is kept constant. The annulus area is proportional to the rise height of the float, i.e. a certain height of the float represents the magnitude of the flow. When the float moves up and down, the position is transmitted to an external indicator in a magnetic coupling mode, the pointer of the indicator moves along with the float, and the size of the flow value is linearly indicated by the pointer through the cam plate.

The patent number CN202022051865.4 discloses a metal tube rotameter with an anti-blocking function, which comprises a tube body, wherein a floater is arranged in the tube body and comprises a slide bar, the outer wall of the slide bar is symmetrically and slidably sleeved with two retainers, the outer walls of the two retainers are fixedly connected with the inner wall of the tube body, a blocking block and a balancing weight are fixedly sleeved on the outer wall of the slide bar, a filter tube is fixedly connected with the bottom water inlet end of the tube body, a second mounting ring is fixedly connected with the inner wall of the filter tube, a second filter screen is fixedly connected with the bottom of the second mounting ring, a rotating shaft is arranged in the filter tube, the outer wall of the rotating shaft is rotatably sleeved with a second retainer, and a turbine is fixedly connected with the bottom end of the rotating shaft; according to the utility model, through the arrangement of the first filter screen and the second filter screen, most foreign matter impurities in the liquid can be effectively filtered, so that a large amount of sediment is prevented from being generated on the surface of the rotor, and the accuracy of the rotor flowmeter is ensured.
