Abstract
A torque-type propeller flowmeter comprises a measuring tube which is provided with an inflow mouth of the fluid and an outflow of the fluid, an impeller which is arranged in the measuring tube, and a cylindrical torque transducer which is arranged in the measuring tube by a fixed bolster, wherein, the impeller is rigidly and fixedly connected with the cylindrical torque transducer, and the inside of the transducer is provided with an electric bridge which consists of strain foils and the electric bridge is connected with a signal processing display device by wires. The flowmeter measures the thrust to the fixed impeller, when the liquid with different flux flows, thus measuring the rate of flow. Since the flowmeter has no movable element, thus the precision of measurement and the reliability are high, and the measuring range is wide with long service life.
Description
Technical field
The utility model relates to a kind of fluid flow rate measurement apparatus, particularly a kind of fluid flow rate measurement apparatus that adopts impeller as measuring sensor.
Background technology
Flowmeter is the measurement liquid of using always, the instrument of gas flow, its structure has multiple form, a kind of employing impeller is arranged as measuring sensor, it is to measure flow rate of fluid by the rotating speed that calculates impeller, and then measured place fluid flow, it as the patent No. 92201822 the disclosed a kind of gas flow meter of utility model, promptly be to utilize this energy conversion principle, the partial pressure of Device in Gas in the pipeline can be transformed into the mechanical energy mode measure design, this gas flow meter mainly contains impeller, turnover compression ring, gauge stand, dial plate and housing and forms.When Device in Gas is flowed through the turnover compression ring, the rotation of impulsion impeller, linear because of the flow and the impeller rotation that flow through impeller, impeller rotation is noted by the classification reduction gear on the dial plate, measure integrated flow.The shortcoming of this class flowmeter is: because rotatable components such as employing impeller, thereby very easily wearing and tearing, reduce its measuring accuracy and serviceable life, poor reliability, and complete machine structure complexity, cost is higher.
Summary of the invention
The purpose of this utility model is to adopt fixedly that impeller designs a kind of measuring accuracy height as measuring sensor, and is simple in structure, good reliability, the moment of torsion formula propeller flowmeter of long service life.
The moment of torsion formula propeller flowmeter of the utility model design, comprise the measuring tube that is provided with fluid inflow entrance and fluid flow export, be located at the impeller in the measuring tube, and be located at cylinder torque sensor in the measuring tube by fixed support, impeller rigidly fixes with the cylinder torque sensor and is connected, sensor internal is provided with the electric bridge of being made up of the stress-strain sheet, and this electric bridge is by lead and signal Processing display device.
The design adopts torque sensor, when the fluid that can measure different flow exactly flows to the fixing thrust of impeller, thereby the flow of measurement fluid.Because there is not movable member, so its measuring accuracy and reliability height, measurement range is wide, long service life.
Description of drawings
Fig. 1, be the structural representation of the utility model moment of torsion formula propeller flowmeter.
Fig. 2, be the structural representation of another embodiment of the utility model moment of torsion formula propeller flowmeter.
Embodiment
Moment of torsion formula propeller flowmeter shown in Figure 1 is the straight pipe type structure, and it comprises the measuring tube 3 that is provided with fluid inflow entrance 1 and fluid flow export 2.The direction setting that impeller 4 is located on the measuring tube 3 interior axis and the longshore current body flows, cylinder torque sensor 5 is located in the measuring tube 3 by fixed support 9, and impeller 4 is fixedlyed connected with cylinder torque sensor 5 by rigidity thick stick 6.The inside of sensor 5 is provided with the resistance bridge of being made up of the stress-strain sheet, and this electric bridge is connected with signal Processing display device 7 by lead.When fluid flows at measuring tube 3, can be to producing thrust with fluid flow direction impeller blade 8 at an angle, thereby produce moment of torsion to axis, this moment of torsion is passed to torque sensor 5 through rigidity thick stick 6 losslessly, stress-strain sheet by sensor 5 inside, stress is converted into electric signal, after signal Processing display device 7 is handled, shows flow value again.
Moment of torsion formula propeller flowmeter shown in Figure 2 is the direction-changing type structure, and each parts is formed identical with Fig. 1.
Claims (1)
- Moment of torsion formula propeller flowmeter, comprise the measuring tube that is provided with fluid inflow entrance and fluid flow export, be located at the impeller in the measuring tube, it is characterized in that: also comprise by fixed support and be located at cylinder torque sensor in the measuring tube, impeller rigidly fixes with the cylinder torque sensor and is connected, sensor internal is provided with the electric bridge of being made up of the stress-strain sheet, and this electric bridge is connected with the signal Processing display device by lead.
