Description

An intelligent turbine flowmeter

Technical Field

The utility model relates to the technical field of water flow measurement equipment, in particular to an intelligent turbine flow meter.

Background Art

The intelligent turbine flowmeter is a velocity flow meter based on the principle of conservation of momentum. The fluid impacts the impeller, causing it to rotate. The rotation speed of the impeller changes with the flow rate, and the flow value is calculated based on the impeller speed. When the measured fluid passes through the flowmeter, the fluid impacts the impeller blades after passing through the rectifier. Since there is an inclination angle between the impeller blades and the fluid flow direction, the impact force of the fluid produces a torque on the impeller, causing the impeller to overcome the mechanical friction resistance torque and rotate. Its rotation speed is approximately proportional to the volume flow of the measured fluid. The measurement of the fluid volume by the intelligent turbine flowmeter is based on the number of rotations of the impeller. It mainly uses a magnetoelectric conversion device or a mechanical output device to convert the number of impeller rotations into electrical pulses, which are sent to the secondary instrument of the intelligent turbine flowmeter for calculation and display. The number of electrical pulses per unit time and the cumulative number of electrical pulses reflect the instantaneous flow and cumulative flow of the measured fluid medium.

At present, it is difficult to isolate the impurities mixed in the circulating medium of the smart turbine flowmeters on the market when they are in use. When the impurities enter the pipeline and pass through the turbine flowmeter, they will cause wear or jamming of the turbine, bearings or other components, resulting in unstable impeller structure and out-of-round rotation, which will affect the detection of flow data. The service life of the flowmeter cannot be guaranteed, which reduces the practicality. Secondly, when the smart turbine flowmeter is installed on the water pipe and the liquid is detected, it is difficult to control the change of liquid flow to perform detection of different flow rates. When the work is completed, the smart turbine flowmeter needs to be disassembled, which is time-consuming and labor-intensive, thus affecting the work of the turbine flowmeter and reducing work efficiency.

The blocks 9 are connected by a rotating shaft 8, a first card slot 21 is provided on the inner wall of the shell 1, a filter screen 10 is provided inside the shell 1, the filter screen 10 can filter out impurities in the liquid, and prevent the impurities in the liquid from entering the turbine flowmeter, which affects its service life and the accuracy of the detection, a card block 11 is slidably installed on one side of the filter screen 10, a second through slot 12 is provided on the side wall of the shell 1, a sleeve 13 is fixedly installed on the end of the second through slot 12, a round plug 14 is slidably installed on the bottom of the sleeve 13, and a pressure gauge 15 is fixedly installed on the top of the sleeve 13.

Please refer to Figures 1 to 7. A valve body 16 is fixedly installed at one end of the shell 1. The bottom of the valve body 16 is located inside the shell 1 and a ball 17 is rotatably installed. Sealing seats 20 are rotatably installed on both sides of the ball. A second slot 171 is provided on the top of the ball 17. A valve stem 18 is rotatably installed inside the second slot 171. A handle 19 is fixedly installed on the top of the valve stem 18. A sealing strip is provided on the outer ring of the filter 10. The sealing strip is engaged with the first slot 21 to ensure the sealing between the filter 10 and the shell 1. The inner diameter of the ball 17 is the same as that of the shell 1, and the outer diameter of the ball 17 is smaller than that of the shell 1. It can be ensured that the side can completely block the liquid in the shell 1 when closed, so that the liquid enters the shell 1 conveniently. The water pressure change is detected by sliding the round plug 14 inside the sleeve 13.

When the pressure gauge 15 reaches the set value, the pressure gauge 15 broadcasts a prompt sound.

Working principle: When in use, by docking the two flanges 2 with the flanges on the water pipe, the liquid flows into the shell 1, and the liquid is filtered through the filter 10. The filter 10 blocks foreign matter in the liquid. The liquid after passing through the filter 10 will flow into the guide block 9, and the guide block 9 will guide the liquid. The guided liquid flows into the turbine 6, and the turbine 6 rotates to generate an electrical signal proportional to the liquid flow rate, which is transmitted to the display screen 5 through the sensor 4. The display screen 5 converts the electrical signal into a digital display, thereby realizing the measurement of the flow rate of the liquid in the shell 1;

When the turbine flowmeter detects liquid, the round plug 14 installed inside the sleeve 13 senses the pressure change in the housing 1. When the pressure reaches a certain level, an alarm is sounded. At this time, by twisting the handle 19 clockwise, the handle 19 rotates to drive the valve stem 18, and the valve stem 18 rotates to drive the ball 17, so that the ball 17 rotates to block the liquid flowing into the housing 1. The user pulls the clamping block 11 forward to take the filter 10 out of the housing 1, cleans the foreign matter on the filter 10, and then presses the clamping block 11 to install the filter 10 into the housing 1, thereby preventing the housing 1 and the turbine 6 from being blocked by foreign matter.

After the filter 10 is installed, the handle 19 is twisted counterclockwise, and the handle 19 rotates to drive the valve stem 18, and the valve stem 18 rotates to drive the ball 17, so that the ball 17 rotates to allow the liquid in the housing 1 to flow into the turbine flowmeter for detection.
