[0002] A vortex flow meter is a volumetric flow meter designed 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. Its characteristics include low pressure loss, a wide measuring range, high accuracy, and it is virtually unaffected by parameters such as fluid density, pressure, temperature, and viscosity when measuring volumetric flow rate under operating conditions.

[0003] The utility model disclosed in CN219694277U is a vortex flow meter, including a test tube. A pipe is provided on one side of the test tube, and a convenient installation component is provided inside the test tube corresponding to the pipe. A storage sleeve is provided at the upper end of the test tube, and an adjustment sleeve is provided inside the storage sleeve. A convenient adjustment component is provided inside the storage sleeve corresponding to the adjustment sleeve.

[0004] As shown in the above utility model, the existing vortex flow meter achieves convenient connection between the test tube and the pipeline by setting a convenient installation component, thereby improving the convenience of installing the vortex flow meter. However, this method can only move the display device back and forth, and cannot be adjusted up and down or at an angle as needed, which affects the display effect. At the same time, the probe is fixedly connected to the test tube in this method, making it inconvenient to disassemble and replace when damaged. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides two technical solutions:

[0028] First implementation: A high-temperature vortex flow meter with heat insulation effect, including a connecting pipe 1, an adjusting component 2, a display instrument 3, and a detection component.

[0029] A heat insulation sleeve 14 for heat insulation is fitted on the outside of the connecting pipe 1. The heat insulation sleeve 14 on the outside of the connecting pipe 1 is composed of two semi-ring heat insulation components 141. The two ends of the two semi-ring heat insulation components 141 are fixed together by U-shaped clips 142 and multiple micro bolts to stably connect the two semi-ring heat insulation components 141. The inner cavity of the connecting pipe 1 is provided with a turbulence column 12 for disturbing the fluid. The flanges at both ends of the connecting pipe 1 are connected to the external pipe through shock-absorbing components. The shock-absorbing components at the flanges of the connecting pipe 1 are shock-absorbing pads 11 or shock-absorbing sheets.

[0030] Adjusting component 2 is located at the top of connecting pipe 1 and is used to install display instrument 3. Adjusting component 2 adjusts the display height of display instrument 3 through telescopic mechanism. Telescopic mechanism on adjusting component 2 includes fixed sleeve 21 fixed at the middle of the top of connecting pipe 1. Fixed sleeve 21 has multiple heat dissipation holes 211 for rapid heat dissipation. Multiple heat dissipation holes 211 are evenly distributed. A threaded knob 22 is connected to the upper side of fixed sleeve 21 through a screw hole. A movable rod 23 that can move up and down is inserted into the inside of fixed sleeve 21. A heat insulation pad 24 for heat insulation is sleeved on the outside of movable rod 23. Fixed sleeve 21 and movable rod 23 cooperate to adjust the height of display instrument 3. The movement is limited by threaded knob 22 so that display instrument 3 can maintain a stable display height. A connecting wire for electrical connection is provided at the bottom of movable rod 23. A wire also runs through the inside of movable rod 23. One end of the wire is electrically connected to the connecting wire, and the other end of the wire is electrically connected to display instrument 3.

[0031] The adjusting component 2 adjusts the display angle of the display instrument 3 through its angle adjustment mechanism. The angle adjustment mechanism on the adjusting component 2 includes an arc-shaped bracket 25 fixed to the top of the movable rod 23 for mounting the display instrument 3. The arc-shaped bracket 25 has a semi-circular structure. Damping sleeves 26 for damping and limiting are fixed on the inner sides of both ends of the arc-shaped bracket 25. After the display instrument 3 is rotated to a certain angle, the damping sleeves 26 limit the display instrument 3 to that angle.

[0032] The display instrument 3 is used to display the flow rate data of the fluid in the connecting pipe 1. The display instrument 3 is electrically connected to the connecting line in the telescopic mechanism. Both ends of the display instrument 3 are fixed with connecting shafts 31. The connecting shafts 31 are movably connected to the arc-shaped bracket 25 through bearings. The connecting shafts 31 are sleeved on the inner side of the damping sleeve 26 and cooperate with the damping sleeve 26 to limit the display instrument 3, so that the display instrument 3 can rotate to any angle.

[0033] The second embodiment differs from the first embodiment in that the detection element is located inside the connecting pipe 1. The detection element is installed in the middle of the inner cavity of the connecting pipe 1 via a detachable structure and is connected to a threaded groove 13 within the connecting pipe 1 for detecting the fluid within the connecting pipe 1. The threaded groove 13 within the connecting pipe 1 is electrically connected to a connecting wire via a conductive sheet. The detection element includes a probe 41 located inside the connecting pipe 1 for detecting fluid flow. A connector 42 is fixed to the top of the probe 41. The connector 42 is connected to the threaded groove 13 within the connecting pipe 1 via internal and external threads and is electrically connected to a conductive sheet within the threaded groove 13. This allows for quick disassembly and replacement of the probe 41 when damaged. A rubber block 43 is provided at the connection point between the connector 42 and the probe 41 for sealing. The rubber block 43 contacts the inner top wall of the connecting pipe 1 to seal the opening of the threaded groove 13, preventing fluid from entering the threaded groove 13 and improving the stability of the detection.

[0034] When this device is in operation, it first connects to the external pipeline through the flanges and shock absorbers at both ends of the connecting pipe 1. Then, the probe 41 in the detection component inside the connecting pipe 1 detects the fluid that has passed through the turbulence column 12. The detection result is displayed on the display instrument 3. The display height of the display instrument 3 can be adjusted by the fixed sleeve 21 and the movable rod 23, and it can be limited by the threaded knob 22. By rotating the display instrument 3, the display angle of the display instrument 3 can be adjusted. The damping sleeve 26 and the connecting shaft 31 can cooperate to limit the display instrument 3, so that the display instrument 3 can be automatically limited after rotating to any angle, which improves the display effect and stability of this device. The connector 42 on the probe 41 is connected to the threaded groove 13 on the connecting pipe 1 through internal and external threads, which makes it easy to quickly disassemble and replace the probe 41 after it is damaged, thus improving the working efficiency of this device.
