Description

Technical Field

[0001] This application relates to the field of ultrasonic vortex instruments, and in particular to an ultrasonic vortex instrument with adjustable generator direction. Background Technology

[0002] Currently, the ultrasonic vortex meter used in the market is a velocity-type instrument based on the combination of the Karman vortex street principle and ultrasonic measurement technology. Based on the Karman vortex street principle, in order to ensure effective detection of the vortices generated by the generator, the generator is arranged upstream of the ultrasonic transducer along the flow direction. In this upstream position, the fluid first flows past the generator to generate vortices, and then the transducer measures the vortices.

[0003] Ultrasonic vortex meters typically come with a flow direction indicator on the meter body. Normally, the direction of the flow direction indicator aligns with the installation direction of the generator inside the meter body. During installation, the meter must be installed according to the direction of the flow direction indicator to ensure effective vortex generation. However, during the installation of the flow direction indicator, it is highly possible for the indicator to be installed in the wrong direction. If the meter is installed on the pipeline according to the direction indicated by the flow direction indicator, the generator and the liquid flow in opposite directions, preventing the generator from generating vortices effectively and affecting the meter's detection. Furthermore, in practical applications, even if the flow direction indicator is installed correctly, workers may still install the meter backwards, causing the generator and liquid flow in opposite directions, again preventing vortex generation and affecting the meter's detection.

[0004] When the generator is installed in the opposite direction to the liquid flow, it will cause a large deviation in the instrument's detection data. In this case, the entire instrument needs to be disassembled and reinstalled to make the generator's installation direction consistent with the fluid flow direction in the pipeline. When disassembling and reassembling the entire instrument, the pipeline needs to be shut down and depressurized and drained. Not only is the disassembly and reassembly process cumbersome, but it also involves a large workload, high labor intensity, and a long duration, which has a significant impact on the normal operation of the system. Summary of the Invention

[0005] To address the aforementioned technical problems, this application provides an ultrasonic vortex meter with an adjustable generator direction. By replacing the connection between the generator and the meter body with a detachable one, and using stationary and moving end caps to fix the generator, the installation direction of the generator can be adjusted within the meter body as needed. Compared to the traditional method where the generator installation direction is opposite to the liquid flow direction within the meter body, requiring the entire ultrasonic vortex meter to be disassembled from the pipeline and reinstalled, this significantly reduces workload and labor intensity, and offers faster replacement speed, shorter time, and higher efficiency.

[0006] This application provides an ultrasonic vortex instrument with adjustable generator direction, which adopts the following technical solution: An ultrasonic vortex generator with adjustable generator direction, comprising: Surface; The meter head is located at the top of the meter body; The generator is inserted inside the surface body; The stationary end cap is fixedly connected to the bottom of the generator and detachably connected to the wall of the meter body tube, and is used to adjust the direction of the generator inside the meter body; The moving end cap is detachably connected and fixed to the wall of the meter body tube, and is also detachably connected to the top of the generator body to fix the top of the generator body. The measuring transducer is mounted on the meter body and located downstream of the generator; Two sets of mounting slots are provided on the meter body and distributed on both sides of the generator along the axial direction of the meter body for mounting the measuring transducer; The sealing element is located in the mounting groove upstream of the generator on the meter body.

[0007] Preferably, the bottom of the stationary end cap is provided with a flow direction indicator.

[0008] Preferably, the moving end cap has a groove on the side facing the generator, and the top of the generator is inserted into the groove.

[0009] Preferably, a first sealing ring for sealing is provided between the stationary end cap and the watch body.

[0010] Preferably, a second sealing ring for sealing is provided between the moving end cap and the watch body.

[0011] Preferably, a third sealing ring is provided between the measuring transducer and the meter body for sealing.

[0012] Preferably, a fourth sealing ring for sealing is provided between the sealing element and the body.

[0013] Preferably, the sealing element is a backup transducer.

[0014] Preferably, the sealing element is a sealing head.

[0015] Preferably, the outer wall of the meter body is provided with a protective cover for protecting the transducer and the sealing component, and the measuring transducer and the sealing component are both located between the meter body and the protective cover.

[0016] In summary, this application includes the following beneficial technical effects: 1. This application replaces the connection between the generator and the meter body with a detachable one, and uses stationary end caps and moving end caps to fix the generator, so that the installation direction of the generator can be adjusted within the meter body as needed. Compared with the traditional method where the installation direction of the generator is opposite to the liquid flow direction within the meter body, requiring the entire ultrasonic vortex instrument to be disassembled from the pipeline and reinstalled, this greatly reduces the workload and labor intensity, and the replacement speed is fast, the time is short, and the efficiency is high.

[0017] 2. This application provides a flow direction indicator on the static end cap, which facilitates the identification of the installation direction of the generator by the staff.

[0018] 3. The sealing component in this application offers two options: a backup transducer and a sealing head. This allows users to choose according to their actual needs. If the backup transducer is selected, when the direction of the generator is opposite to the flow direction of the liquid in the meter body, only the direction of the generator needs to be adjusted. Furthermore, the direction of the generator can be adjusted under pressure. After the direction of the generator is adjusted, the flow rate of the fluid in the meter body can be measured using the backup transducer. If the sealing head is selected, when the direction of the generator is opposite to the flow direction of the liquid in the meter body, not only does the direction of the generator need to be adjusted, but the positions of the sealing head and the measuring transducer also need to be swapped. Users can choose according to their actual needs and overall usage costs. Attached Figure Description

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] This application discloses an ultrasonic vortex instrument with adjustable generator direction.

[0027] Reference Figure 1 and Figure 2 The ultrasonic vortex instrument includes a body 11, a head 12, a generator, a stationary end cap 14, a moving end cap 15, a measuring transducer 16, and a sealing component 17.

[0028] Both ends of the body 11 are connected to the pipe flanges.

[0029] The meter head 12 is installed and fixed to the top of the pipe wall of the meter body 11, and the meter head 12 and the meter body 11 are fixed by bolt connection.

[0030] The generator 13 is used to generate vortices inside the dial indicator 11 to facilitate measurement by the transducer 16. The generator 13 is inserted inside the dial indicator 11, and to allow adjustment of its orientation within the dial indicator 11, a stationary end cap 14 and a moving end cap 15 are respectively fixedly connected to both ends of the generator 13. The stationary end cap 14 is fixedly connected to the generator 13, and the stationary end cap 14 and the generator 13 can also be integrally formed. The generator 13 is a right quadrangular prism with an isosceles trapezoidal base.

[0031] Reference Figure 1 and Figure 2 Specifically, the bottom of the meter body 11 has a bottom opening for installing the stationary end cap 14. The stationary end cap 14 is installed at the bottom opening of the meter body 11, and the stationary end cap 14 is detachably connected and fixed to the meter body 11. The detachable connection and fixing includes, but is not limited to, bolt connection, plug-in or snap-fit ​​connection. In this embodiment, the stationary end cap 14 is bolted to the meter body 11. In use, when it is necessary to adjust the direction of the generator 13 inside the meter body 11, the stationary end cap 14 is fixed to the meter body 11 by bolts passing through different bolt holes.

[0032] In addition, to facilitate staff to identify the direction of the generator 13, a flow direction indicator 141 for indicating the direction of the generator 13 is provided at the bottom of the stationary end cover 14.

[0033] Similarly, the moving end cap 15 is located on the top of the watch body 11, and the moving end cap 15 is used to fix the top of the generator 13. The top of the watch body 11 has a top opening for installing the moving end cap 15. The moving end cap 15 is installed at the top opening of the watch body 11, and the moving end cap 15 is also detachably connected to the watch body 11. This detachable connection includes, but is not limited to, bolt connections, plug-in connections, or snap-fit ​​connections. In this embodiment, the moving end cap 15 is also bolted to the watch body 11.

[0034] Reference Figure 2 and Figure 3 The moving end cap 15 has an isosceles trapezoidal groove 151 on the side facing the generator 13, which has the same shape as the bottom surface of the generator 13. The top of the generator 13 is inserted into the groove 151. In use, the installation direction of the moving end cap 15 depends on the way the generator 13 is inside the watch body 11. When it is necessary to adjust the direction of the generator 13 inside the watch body 11, the direction of the moving end cap 15 on the watch body 11 needs to be adjusted at the same time.

[0035] Furthermore, the position of the moving end cover 15 can be selected according to actual needs. It can be located on the top of the watch body 11 alone, or it can be located in the area covered by the watch head 12, that is, the moving end cover 15 is located between the watch head 12 and the watch body 11.

[0036] Reference Figure 2 In order to improve the sealing effect between the stationary end cover 14 and the instrument body 11, a first sealing ring 18 is provided between the stationary end cover 14 and the instrument body 11 for sealing. The first sealing ring 18 is sleeved on the stationary end cover 14, and the first sealing ring 18 can be an O-ring.

[0037] Similarly, in order to improve the sealing effect between the moving end cover 15 and the watch body 11, a second sealing ring 19 is provided between the moving end cover 15 and the watch body 11 for sealing. The second sealing ring 19 is sleeved on the moving end cover 15, and the second sealing ring 19 can be an O-ring.

[0038] Specifically, the meter body 11 has two sets of mounting slots 111, which are located on both sides of the generator 13 along the axial direction of the meter body 11. Both sets of mounting slots 111 are used to install the measuring transducer 16, and the mounting slots 111 can be internal threaded holes.

[0039] Reference Figure 2 The measuring transducer 16 is installed in the set of mounting slots 111 downstream of the generator 13. The measuring transducer 16 is electrically connected to the meter head 12 and is used to measure the flow rate of the fluid in the meter body 11.

[0040] The measuring transducer 16 can be selected according to actual needs. For example, a common measuring transducer 16 usually includes a transmitting part and a receiving part. Therefore, each set of mounting slots 111 on the meter body 11 includes two mounting slots 111 symmetrically distributed along the radial direction of the meter body 11.

[0041] To improve the sealing between the transducer and the body 11, a third sealing ring 20 is installed between the transducer and the body 11 for sealing. The third sealing ring 20 is fitted onto the transducer and can be an O-ring.

[0042] Reference Figure 2 The sealing component 17 is installed in the set of mounting slots 111 upstream of the generator 13. The sealing component 17 is used to block the mounting slots 111 upstream of the generator. The sealing component 17 can be selected according to actual needs. Specifically, in this embodiment, the sealing component 17 can be a spare transducer. If a spare transducer is selected, the spare transducer needs to be electrically connected to the meter head 12. Furthermore, when the direction of the generator needs to be adjusted later, the positions of the measuring transducer 16 and the spare transducer do not need to be swapped. The direction of the generator 13 can be adjusted directly. At this time, the flow rate of the fluid in the meter body 11 is measured using the spare transducer.

[0043] Reference Figure 4 In other embodiments, the plugging component 17 may also be a plugging head. If the plugging component 17 is a plugging head, then when the direction of the generator needs to be adjusted later, the positions of the measuring transducer 16 and the plugging head need to be swapped, and then the measuring transducer 16 is used to continue to measure the flow rate of the fluid in the meter body 11.

[0044] In order to improve the sealing performance between the sealing element 17 and the meter body 11, a fourth sealing ring 21 for sealing is installed between the sealing element 17 and the meter body 11. The fourth sealing ring 21 is sleeved on the sealing element 17, and the fourth sealing ring 21 can be an O-ring.

[0045] When in use, the number of transducers can be selected according to the actual situation, and each transducer can be electrically connected to the body 11.

[0046] Reference Figure 2 and Figure 5To better protect the measuring transducer 16 and the sealing component 17, a protective cover 22 is also installed on the meter body 11. There are two protective covers, and the two protective covers 22 are located on both sides of the meter body 11 in the radial direction. Each protective cover 22 covers the measuring transducer 16 and the sealing component 17 on the same side of the meter body 11. In order to protect the electrical connection wire between the measuring transducer 16 and the meter body 11 and the electrical connection wire between the spare transducer and the meter body 11, the electrical connection wire can be wired in a concealed manner. Specifically, a wire hole 112 is opened on the meter body 11, and the electrical connection wire passes through the wire hole 112 to connect to the meter head 12.

[0047] When in use, the staff can install the ultrasonic vortex instrument according to the flow direction mark 141 at the bottom of the stationary end cover 14. Since the flow direction mark 141 is integrated into the stationary end cover 14 which is fixedly connected to the generator, the problem of the flow direction mark 141 being inconsistent with the direction of the generator 13 caused by the traditional installation of the flow direction mark 141 on the instrument body 11 is solved. Additionally, if, after the installation of the ultrasonic vortex meter is completed, it is found that the direction of the generator 13 is opposite to the liquid flow direction inside the meter body 11, different solutions can be implemented depending on the selection of the sealing component 17, as follows: If the backup transducer is selected for the sealing component 17, the operator can close the valve groups on both sides of the ultrasonic vortex instrument, depressurize the liquid in the instrument, remove the moving end cover 15 and the stationary end cover 14, and then adjust the direction of the generator 13 by rotating the generator 13 180 degrees and reinstalling the stationary end cover 14 and the moving end cover 15 onto the instrument body 11 so that the direction of the generator 13 is consistent with the flow direction of the liquid in the pipeline; or the operator can adjust the direction of the generator 13 under pressure by unscrewing the bolts on the stationary end cover 14 and the moving end cover 15, rotating the stationary end cover 14 and the moving end cover 15 180 degrees simultaneously, and then re-screwing the bolts on the stationary end cover 14 and the moving end cover 15 onto the instrument body 11 to fix them so that the direction of the generator 13 is consistent with the flow direction of the liquid in the pipeline. After that, during use, the flow rate of the fluid in the instrument body 11 is measured using the backup transducer.

[0048] If the plugging component 17 is a plugging head, the operator needs to close the valve groups on both sides of the ultrasonic vortex instrument and depressurize and drain the liquid in the instrument. Then, remove the moving end cover 15 and the stationary end cover 14, and adjust the direction of the generator 13 by rotating the generator 13 180 degrees. Then, reinstall the stationary end cover 14 and the moving end cover 15 onto the instrument body 11 so that the direction of the generator 13 is consistent with the flow direction of the liquid in the pipeline. Then, remove the two protective covers 22, swap the position of the measuring transducer 16 with the position of the plugging head, and reinstall it onto the instrument body 11. Then, install the protective cover 22 onto the instrument body 11 so that the measuring transducer 16 can measure the flow rate of the fluid in the instrument body 11.

[0049] Compared with the traditional method of disassembling the entire ultrasonic vortex instrument from the pipeline and reversing its installation when the installation direction of the generator 13 is opposite to the liquid flow direction, the technical solution of this application greatly reduces the workload and labor intensity, and the replacement speed is fast, the time is short and the efficiency is high.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
