Description

Technical Field

[0001] This invention belongs to the field of metering equipment technology, and in particular relates to an integrated vortex flow meter with remote reading capability. Background Technology

[0002] A vortex flow meter is a fluid vibration-type flow measurement instrument based on the Karman vortex street principle, widely used for measuring the flow rate of media in industrial pipelines. When fluid flows through a non-streamlined vortex generator in a pipe, regular vortices are alternately generated on both sides, forming a "Karman vortex street," the frequency of which is proportional to the flow velocity. The flow rate can be calculated by detecting the vortex frequency. This instrument has advantages such as simple structure, no moving parts, convenient installation and maintenance, wide measurement range, and low pressure loss. It is suitable for various media such as gases, liquids, and steam, and plays an important role in industries such as petroleum, chemical, metallurgy, and power.

[0003] A Chinese patent application (or patent) with publication number CN219391003U discloses a vortex flow meter, including: a tube body, a converter, a strain sensor, a vortex generator, and a dynamic seal. The tube body has a mounting hole on its side, and a dynamic seal is embedded in the mounting hole. The strain sensor is detachably mounted on the outer surface of the tube body. A portion of the elastic sensitive element of the strain sensor extends through the dynamic seal into the inner side of the tube body. The converter is located on the outer side of the tube body and is signal-connected to the strain sensor.

[0004] However, the above-mentioned device still has the following problems during implementation: During long-term operation of a vortex flow meter, the sensor is always in the flowing medium. It is prone to signal attenuation or distortion due to the deposition of particles, oil, or scale in the medium on the surface, which affects the measurement accuracy. To restore performance, the sensor needs to be removed for cleaning or replacement. However, this operation requires closing the valves before and after the sensor, causing a short system shutdown and affecting the continuity of production.

[0005] To address this issue, we provide an integrated vortex flow meter with remote reading capability. Summary of the Invention

Through the structural cooperation of the detection component, sealing component, and connecting component, it solves the problem in the prior art where the flow meter sensor is placed in the flowing medium, and after long-term use, the sensor surface will be covered with impurities, causing deviations in the detection data. This requires closing the valve, removing the sensor for cleaning or replacement, resulting in downtime.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution.

[0031] The technical solutions of the present invention will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments. Example 1

[0032] Please see Figures 1-9This invention relates to an integrated vortex flow meter with remote reading capability, comprising a support pipe 1, a vertical pipe 2 connected to the top of the support pipe 1, and a flow meter body 3 mounted at the other end of the vertical pipe 2; a detection component 4 is disposed inside the support pipe 1, the detection component 4 including an installation pipe 401 mounted at the top of the support pipe 1, a detection rod 402 passing through the top of the installation pipe 401, a sensor 403 and a temperature sensor 404 mounted at the bottom of the detection rod 402, a wire 405 mounted at the top of the detection rod 402, a controller 406 mounted on one side of the flow meter body 3, and a wireless transmitter 407 mounted on one side of the controller 406, which detects and compensates for temperature difference data of the flow meter body 3 through the detection component 4; a sealing component 5 is disposed on one side of the support pipe 1, the sealing component 5 including a mounting pipe 401 mounted on the vertical pipe 1, the vertical pipe 2 connected to the vertical pipe 2, and a flow meter body 3 mounted on the vertical pipe 2; the vertical pipe 2 is connected to the vertical pipe 3, and the flow meter body 3 is mounted on the vertical pipe 3, and the vertical pipe 2 ... The telescopic tube 501 on the surface of the tube 401, the ring 502 slidably connected to the surface of the mounting tube 401, the tension spring 503 sleeved on the surface of the mounting tube 401, the sealing plate 504 set at the bottom of the mounting tube 401, the sealing plug 505 and the moving rod 506 installed on the top of the sealing plate 504, and the moving rod 506 are sealed by the sealing assembly 5 to seal the movement of the detection rod 402; a connecting assembly 6 is provided on one side of the support tube 1. The connecting assembly 6 includes a connecting tube 601 set on one side of the support tube 1, a connecting ring 602 installed inside the connecting tube 601, a sealing inner ring 603 installed on one side of the connecting tube 601, a slip ring 604 installed on one side of the sealing inner ring 603, and a convex tube 605 installed inside the support tube 1. The connecting assembly 6 provides a flexible connection between the support tube 1 and the external pipeline.

[0033] Specifically: Support pipe 1 serves as the channel for fluid flow; vertical pipe 2 connects support pipe 1 to flowmeter body 3, enabling stable transmission of fluid signals to flowmeter body 3. Flowmeter body 3 monitors fluid flow in real time; mounting pipe 401 provides an installation and sliding channel for detection rod 402, ensuring smooth up-and-down movement of detection rod 402. Detection rod 402 supports and drives sensor 403 and temperature sensor 404 to move up and down. Sensor 403 detects the vortex frequency generated by fluid flow to calculate flow rate, and temperature sensor 404 collects fluid temperature data. The data facilitates subsequent temperature difference compensation, improving the accuracy of flow measurement. Wire 405 transmits the signals collected by sensor 403 and temperature sensor 404 to controller 406, ensuring stable and reliable signal transmission. Controller 406 receives and processes the data from sensor 403 and temperature sensor 404, performs temperature difference compensation calculations, and improves the accuracy and reliability of flow measurement. Wireless transmitter 407 remotely sends the processed flow data to an external control terminal, enabling remote meter reading and avoiding the tedious manual on-site meter reading. Ring 502 is installed in the pipe... The surface of the 401 slides and cooperates with the tension spring 503 to provide elastic restoring force when the detection rod 402 moves, ensuring that the sealing plate 504 can automatically reset. The sealing plate 504 is used to seal the lower end of the installation tube 401. When the detection rod 402 is pulled out, it cooperates with the sealing plug 505 to seal the installation tube 401 and prevent fluid leakage. The connecting tube 601 is set on one side of the support tube 1 and connects to the external pipeline to realize quick docking between the flow meter and the pipeline system. The connecting ring 602 is installed inside the connecting tube 601 to provide fixed support for the sealing inner ring 603 and ensure that the sealing inner ring 603 is under pressure. The inner sealing ring 603 is installed on one side of the connecting pipe 601 and cooperates with the convex tube 605 to form a sealing structure. Under pressure, it fits tightly against the convex tube 605 to improve the sealing performance. The slip ring 604 is installed on one side of the inner sealing ring 603 and transmits pressure when the connecting pipe 601 and the support pipe 1 are connected, so that the inner sealing ring 603 is deformed evenly to achieve the best sealing effect. The convex tube 605 is installed inside the support pipe 1 and contacts the inner wall of the inner sealing ring 603. When connected, it pushes the slip ring 604 to realize a soft connection structure and buffer the impact of external pipeline vibration on the flow meter body 3. Example 2

[0034] Please see Figures 1-9Based on Embodiment 1, the sealing assembly 5 further includes a disc 507 mounted on the surface of the detection rod 402, a sealing cap 508 movably connected to the surface of the disc 507, the sealing cap 508 being threadedly connected to the mounting tube 401, the other end of the wire 405 being fixedly connected to the controller 406, one end of the tension spring 503 being fixedly connected to the ring 502, the other end of the tension spring 503 being fixedly connected to the inner wall of the telescopic tube 501, the surface of the ring 502 being slidably connected to the inner wall of the telescopic tube 501, the other end of the moving rod 506 being fixedly connected to the sealing plate 504, and the detection rod 402 being slidably connected to the inner wall of the mounting tube 401.

[0035] Specifically: The disc 507 is mounted on the surface of the detection rod 402 and connected to the sealing cap 508, so that the sealing cap 508 can drive the detection rod 402 to move up and down. The sealing cap 508 is movably connected to the surface of the disc 507 and is connected to the mounting tube 401 by threads. Rotating the sealing cap 508 can drive the detection rod 402 to move up and down. Example 3

[0036] Please see Figures 1-9 Based on Embodiments 1 and 2, a fixing rope 7 is fixedly connected to the top of the support pipe 1, and an installation cap 8 is fixedly connected to the other end of the fixing rope 7 for sealing the installation pipe 401. Flanges 9 are fixedly connected to the surfaces of the connecting pipe 601 and the support pipe 1. A fixing bolt 10 is provided through one side of the flange 9, and a nut 11 is threaded onto the surface of the fixing bolt 10. The surface of the slip ring 604 is slidably connected to the inner wall of the connecting pipe 601. A spring 12 is sleeved on the surface of the sealing inner ring 603. One end of the spring 12 is fixedly connected to the connecting ring 602. A sealing groove 13 is opened on one side of the flange 9, and a sealing element 14 is provided inside the sealing groove 13. The surface of the convex pipe 605 is in contact with the inner wall of the sealing inner ring 603, and one side of the convex pipe 605 is horizontally aligned with the slip ring 604.

[0037] Specifically: The fixing rope 7 connects the support pipe 1 and the mounting cap 8 to prevent the mounting cap 8 from being lost and to facilitate sealing of the mounting pipe 401 at any time. The mounting cap 8 is used to seal the mounting pipe 401 when the detection component 4 is not in use, preventing external impurities from entering the mounting pipe 401. The flange 9 is fixedly connected to the surface of the connecting pipe 601 and the support pipe 1, and a firm connection to the external pipeline is achieved through fixing bolts 10 and nuts 11, facilitating installation and disassembly. The fixing bolts 10 are used to insert into the flange 9, and cooperate with the nuts 11 to lock the two sets of flanges 9, thus achieving the connection between the connecting pipe 601 and the support pipe 1. The flange 9 is fixedly connected by a nut 11 and a fixing bolt 10, which locks the flange 9 to ensure the stability and sealing of the connection. A spring 12 is fitted on the surface of the sealing inner ring 603, with one end fixedly connected to the connecting ring 602. When the connecting pipe 601 is separated from the support pipe 1, the sealing inner ring 603 is automatically reset to facilitate the next connection. A sealing groove 13 is opened on one side of the flange 9 to accommodate the sealing element 14, which enhances the sealing performance of the connection and prevents fluid leakage. The sealing element 14 is set inside the sealing groove 13 and undergoes elastic deformation when the flange 9 is pressed, further enhancing the sealing effect of the connection.

[0038] The working principle of this invention is as follows: When it is necessary to connect the flow meter body 3 to an external pipeline, the operator first aligns the support pipe 1 with the connecting pipe 601, such as... Figure 6 As shown, the connecting pipe 601 is then pushed, which moves the inner sealing ring 603 to the surface of the convex pipe 605. While the connecting pipe 601 is moving, one side of the convex pipe 605 contacts the slip ring 604. Then, the connecting pipe 601 is pushed to press against the support pipe 1. At this time, the slip ring 604 is pushed to move through the convex pipe 605. The slip ring 604 squeezes the inner sealing ring 603. After being squeezed, the inner sealing ring 603 presses against the convex pipe 605, improving the connection sealing between the support pipe 1 and the connecting pipe 601.

[0039] Then, the two sets of flanges 9 are brought close together and pressed against each other to compress the seal 14. Then, the fixing bolts 10 are inserted into the two sets of flanges 9, and the nuts 11 are rotated to seal the support pipe 1 and the connecting pipe 601. After the sealing inner ring 603 and the seal 14 seal between the support pipe 1 and the connecting pipe 601, soft contact is achieved. When the external pipeline vibrates, it can be buffered by the sealing inner ring 603 and the seal 14 to avoid the vibration from affecting the normal detection of the flow meter body 3, thus playing a protective role.

[0040] When the fluid passes through the support pipe 1, the flow meter body 3 detects the fluid, and at the same time, the sensor 403 and the temperature sensor 404 extract the temperature data in the fluid. The temperature sensor 404 transmits the temperature value to the controller 406. The controller 406 integrates the temperature difference value with the value detected by the flow meter body 3 to compensate for the difference caused by the temperature and improve the accuracy of the detection data. Then, the flow value is sent to the external control terminal through the wireless transmitter 407 to realize the function of remote reading and improve the convenience of use.

[0041] After prolonged use, the surfaces of temperature sensor 404 and sensor 403 become covered with dust and require cleaning and replacement. When this occurs, the operator manually rotates the sealing cap 508, causing it to disengage from the mounting tube 401. This rotation moves the disc 507 and detection rod 402 upwards. As the detection rod 402 moves upwards, the tension spring 503 resets the moving rod 506 and sealing plate 504. The sealing plate 504 then moves the sealing plug 505 upwards. When the detection rod 402 disengages from the mounting tube 401, the sealing plug 505 inserts upwards into the mounting tube 401, completing the seal. This allows for cleaning and replacement of sensor 403 and temperature sensor 404 without shutting down the machine, improving ease of use.

[0042] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
