Description

Technical Field

[0001] This utility model belongs to the field of vortex flow meter technology, and in particular relates to a vortex flow meter with a redundant structure. Background Technology

[0002] A vortex flow meter is a volumetric flow meter researched and manufactured based on the Karman vortex street principle to measure the volumetric flow rate, standard volumetric flow rate, or mass flow rate of gases, steam, or liquids. It is mainly used for flow measurement of fluids in industrial pipelines, such as gases, liquids, steam, and other media.

[0003] In related technologies, a redundant vortex flow meter is disclosed, including a flow meter pipe, connecting flanges installed at both ends of the flow meter pipe, and a vortex generator disposed inside the flow meter pipe. Two symmetrical sensors are disposed behind the vortex generator, with the probes of both sensors extending into the flow meter pipe. The ends of the sensors protruding from the flow meter pipe are installed inside the flow meter housing, which is connected to a bracket, which in turn connects to the flow meter head. By installing two relatively independent sensors on a single flow meter, on-site construction costs are significantly reduced, and detection accuracy and stability are improved, making it suitable for industrial production.

[0004] However, the above structure still has shortcomings. During the use of the device, although the detection process can still be carried out by the remaining flow meters after one of the flow meters fails, it is still necessary to stop the delivery of the medium to replace the damaged flow meter, which affects the continuity of production.

[0005] Therefore, it is necessary to provide a new vortex flowmeter with a redundant structure to solve the above-mentioned technical problems. Utility Model Content

Each of the two mounting tubes has a mounting ring fixedly installed at one end. A circular plate is fixedly installed on the mounting ring by bolts, and a vertical rod is fixedly installed on the circular plate. One end of the vertical rod extends into the mounting tube, and a sensor is fixedly installed at one end of the vertical rod. A flow meter head is fixedly installed at the other end of the vertical rod.

[0021] Please refer to the following: Figures 1 to 4 ,in, Figure 1 A three-dimensional structural diagram of the vortex flowmeter with redundant structure provided by this utility model; Figure 2 A cross-sectional view of the vortex flowmeter with redundant structure provided by this utility model. Figure 3 A partial structural schematic diagram of the vortex flowmeter with redundant structure provided by this utility model; Figure 4 This is a schematic diagram of the switching channel structure after the valve core rotates in this utility model. The vortex flowmeter with redundant structure includes: two detection tubes 2, each with an arc-shaped tube 3 fixedly installed at both ends; a valve body 4 fixedly installed at one end of each arc-shaped tube 3; a connecting pipe 5 fixedly installed on the valve body 4; a valve core 6 rotatably installed inside the valve body 4; a valve stem 7 fixedly installed on the top of the valve core 6; the top end of the valve stem 7 extends outside the valve body 4 and is rotatably connected to the valve body 4; and a handwheel 8 is fixedly installed on the top end of the valve stem 7.

[0022] like Figure 3 As shown, an eddy current generator 9 is fixedly installed inside the detection tube 2. Two mounting tubes 10 are fixedly installed on the detection tube 2. An mounting ring 11 is fixedly installed at one end of each of the two mounting tubes 10. A circular plate 12 is fixedly installed on the mounting ring 11 by bolts. A vertical rod 13 is fixedly installed on the circular plate 12. One end of the vertical rod 13 extends into the mounting tube 10. A sensor 14 is fixedly installed at one end of the vertical rod 13. A flow meter head 15 is fixedly installed at the other end of the vertical rod 13.

[0023] By setting up an eddy current generator 9, a mounting pipe 10, a mounting ring 11, a circular plate 12, a vertical rod 13, a sensor 14, and a flow meter head 15, the flow rate of the medium flowing through the detection pipe 2 can be detected.

[0024] like Figure 1 and Figure 2 As shown, there are two of each of the valve body 4, connecting pipe 5, valve core 6, valve stem 7, and handwheel 8;

[0025] By providing two valve bodies 4, connecting pipe 5, valve core 6, valve stem 7, and handwheel 8, the flow path of the medium can be changed when replacing a damaged flow meter.

[0026] like Figure 3As shown, the circular plate 12, the upright rod 13, the sensor 14 and the flow meter head 15 constitute the main body of the vortex flow meter, and two vortex flow meter bodies are set on the detection tube 2;

[0027] By setting up two vortex flow meter bodies, the flow rate of the flowing medium can be detected, and it can be determined whether the flow meter is damaged.

[0028] like Figure 2 As shown, both valve cores 6 are provided with arc-shaped through grooves;

[0029] By setting an arc-shaped through groove, it is possible to easily change the flow channel of the medium after the valve core 6 rotates 135°.

[0030] like Figure 1 and Figure 2 As shown, a flange 16 is fixedly installed at one end of each of the two connecting pipes 5;

[0031] By setting flange 16, it is possible to easily connect the medium flow pipeline to the connecting pipe 5.

[0032] The working principle of the vortex flowmeter with redundant structure provided by this utility model is as follows:

[0033] During use, as the medium passes through the detection tube 2, it comes into contact with the vortex generator 9, generating vortices behind the vortex generator 9. The flow rate of the medium is detected by the sensor 14. At the same time, the flow meter can be judged whether it is damaged by checking whether the readings of the two flow meter gauges 15 are consistent. If it is damaged, the valve stem 7 is rotated by the handwheel 8, and the valve stem 7 rotates the valve core 6 by 135° to change the medium flow channel. After removing the bolts, it can be replaced without affecting production.

[0034] It should be noted that the device structure and accompanying drawings of this utility model mainly describe the principle of this utility model.
