Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of electromagnetic flowmeter testing, specifically, it relates to an electromagnetic flowmeter production testing device. Background Technology
[0002] Electromagnetic flowmeters utilize Faraday's law of electromagnetic induction. Adhering to the principle of ensuring a regular and uniform magnetic field penetrating the fluid cross-section, they employ non-magnetic materials to construct the conduit. Existing electromagnetic flowmeters are generally connected in series in pipelines. However, after successful assembly, there is a lack of dedicated, streamlined testing equipment for these flowmeters, leading to uncertain measurement values from the factory. Patent CN210221216U discloses an electromagnetic flowmeter testing device. This patent includes a main testing pipeline, a supply pipe, a switch valve, an inlet, an auxiliary testing pipeline, the electromagnetic flowmeter to be tested, and a standard flowmeter. Liquid flows from the supply pipe into the main testing pipeline and passes through the electromagnetic flowmeter to be tested. It can measure whether the flowmeter values at different flow rates match those of the standard flowmeter. Comparison of multiple flow rate measurements shows good testing results and a simple structure. However, in actual use, the electromagnetic flowmeter is fixed to the pipeline using flanges, bolts, and nuts, resulting in a long connection process and relatively low testing efficiency.
[0003] In view of this, this utility model is proposed. Utility Model Content

The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0024] like Figures 1 to 5 As shown, an electromagnetic flowmeter production and testing device includes a support base plate 1 and a support placement seat 15.

Sealing connection frames 3 are fixedly installed on the telescopic ends of hydraulic cylinder 12 and hydraulic cylinder 23. The sealing connection frame 3 includes a pressing power plate 22, a connecting rod 21, and a pressing mating plate 20. The pressing power plate 22 is fixedly connected to the hydraulic telescopic rod, and the pressing power plate 22 and the pressing mating plate 20 are connected by the connecting rod 21. A through hole is provided at the center of the 20. One side of the clamping plate 20 connecting rod 21 is sealed to the lower liquid supply pipe 5. A sliding support seat 19 is provided below the sealing connection frame 3. A sliding support guide groove 23 is provided at the upper end of the sliding support seat 19. A standard flow meter 6 is installed on the lower liquid supply pipe 5. The upper end of the lower liquid supply pipe 5 is connected to the upper liquid supply pipe 8 through a telescopic pipe 7. The upper liquid supply pipe 8 is connected to the outlet end of the liquid pump 11. A liquid storage tank 4 is provided below the liquid pump 11. The liquid pump 11 draws out the liquid in the liquid storage tank 4 and supplies it to the detection system.
[0025] Each sealing connection frame 3 is provided with a set of four connecting rods 21, which are evenly distributed along the circumference. The sliding support seat 19 is provided with two sliding support guide grooves 23. The position and specifications of the sliding support guide grooves 23 are adapted to the two connecting rods 21 below to ensure the stability of the horizontal movement of the sealing connection frame 3.
[0026] A sealing ring 16 is provided on the end face of the clamping plate 20 that mates with the flange of the electromagnetic flowmeter. A fixing groove 26 is provided on the outer side of the sealing ring 16. A fixing clamping ring 27 is installed in the fixing groove 26. The fixing clamping ring 27 is connected to the clamping plate 20 by fixing screws 28 to achieve the fixed installation of the sealing ring 16.
[0027] A return liquid pipe 17 is connected to a sealing connection bracket 3 at the end of the support base 15 away from the supply liquid pipe 5. A standard flow meter 18 is installed on the return liquid pipe 17. The upper end of the return liquid pipe 17 is connected to the return liquid upper pipe 24 through a telescopic pipe 7. The standard flow meter 18 is used to detect the flow rate of the return liquid.
[0028] The other end of the return liquid pipe 24 is connected to the filter box 12. The filter box is fixedly installed on the support base plate 1. The filter box 12 and the storage tank 4 are connected by a pipe so that the liquid used for testing is filtered by the filter box 12 and then returned to the storage tank 4 for recycling.
[0029] Both the supply pipe 8 and the return pipe 24 are equipped with pipe support frames 9. The supply pipe 8 is equipped with a solenoid valve 10. The support base 25 is located below the support base plate 1. The solenoid valve 10 is used to control the liquid supply during the detection process.
[0030] The working principle of this utility model is as follows: When testing an electromagnetic flowmeter, the electromagnetic flowmeter to be tested is placed on a support base 15. The upper part of the support base 15 is provided with an arc-shaped support structure adapted to the electromagnetic flowmeter. Hydraulic cylinder 12 and hydraulic cylinder 23 are activated. Hydraulic cylinder 12 and hydraulic cylinder 23 respectively drive the matching sealing connection frame 3 to move towards the electromagnetic flowmeter to be tested. A sealing ring 16 is provided on the pressing plate 20 of the sealing connection frame 3. The sealing ring 16 can make the pressing plate 20 fit precisely with the flange surface of the electromagnetic flow valve, ensuring the sealing of the connection between the electromagnetic flow valve and the return liquid lower pipe 17 and the supply liquid lower pipe 5, and realizing the rapid testing connection of the electromagnetic flow valve to be tested. Since a telescopic pipe 7 is provided between the supply liquid upper pipe 8 and the supply liquid lower pipe 5, and between the return liquid upper pipe 24 and the return liquid lower pipe 17, the stability of the connection between the inlet and return liquid circulation pipes is ensured during the movement of the sealing connection frame 3. Hydraulic cylinder 12 and hydraulic cylinder 23 extend and retract synchronously.
[0031] The pump 11 draws liquid from the storage tank 4, which then flows through the upper supply pipe 8, the telescopic pipe 7, and the lower supply pipe 5 into the electromagnetic flow valve. After passing through the flow electromagnetic valve 10, the liquid flows through the lower return pipe 17, the telescopic pipe 7, and the upper return pipe 24 into the filter box 12. Standard flow meter 6 and standard flow meter 18 are installed on the lower supply pipe 5 and the lower return pipe 17, respectively. By observing the flow rate of the standard flow meter 6, the standard flow meter 18, and the electromagnetic flow meter being tested, it is determined whether the electromagnetic flow meter being tested is qualified. The standard flow meter 6 and the standard flow meter 18 are standard electromagnetic flow meters, which can be obtained in advance through experiments or other methods. Of course, in other embodiments, other types of flow meters such as rotor flow meters can also be used as standard flow meters, without specific limitations.
[0032] The electromagnetic flowmeter production and testing device of this utility model is equipped with a support base 15 for supporting and placing the electromagnetic flowmeter to be tested. On both sides of the support base 15, there are corresponding sealing connection frames 3 and hydraulic cylinders. The hydraulic cylinders drive the sealing connection frames 3 to move horizontally, thereby causing the two ends of the electromagnetic flowmeter to be tested to be sealed and connected to the inlet and outlet liquid pipes. No disassembly or loosening of bolts is required, which can effectively improve the efficiency of disassembly and assembly during the testing process. The outer side of the clamping plate 20 is connected to a lower pipe, and a telescopic rod is provided between the lower pipe and the upper pipe. A sealing ring 16 is provided on the mating surface of the clamping plate 20 and the electromagnetic flowmeter flange. The sealing ring 16 cooperates with the sealing platform structure on the outer side of the electromagnetic flow valve flange, which can effectively ensure the sealing performance of the connection between the clamping plate 20 and the flange, thereby ensuring the sealing performance of the connection between the lower pipe and the electromagnetic flowmeter, and ensuring the testing and usage effect.
