Description

Technical Field

[0001] This application relates to the field of steam vortex metering, and in particular to a steam vortex meter with adjustable generator position and direction. Background Technology

[0002] A steam vortex meter is an instrument used for measuring the flow rate of steam media. It is mainly used for measuring the flow rate of steam media in industrial pipelines. The steam vortex meter is characterized by low pressure loss, large measuring range, and high accuracy. When measuring the volumetric flow rate under operating conditions, it is almost unaffected by parameters such as the density, pressure, temperature, and viscosity of the steam media.

[0003] The measurement principle of a steam vortex meter is to set up a vortex generator inside the meter body, and then install a stress probe for measurement downstream of the generator, or in other words, install the generator upstream of the stress probe. The stress probe measures the vortex generated after passing through the generator. The upstream of the stress probe is the front end of the stress probe along the steam flow direction inside the meter body. That is, the steam first flows through the generator to generate vortices, and then the stress probe measures the vortices.

[0004] Steam vortex meters typically come with a flow direction indicator mounted on the meter body. Normally, the direction of the flow direction indicator aligns with the installation direction of the generator within the meter body, as well as the order in which the generator and stress probe are installed. During installation, the meter must be installed according to the direction of the flow direction indicator to ensure the generator effectively produces vortices. 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 steam flow will be opposite, preventing the generator from effectively generating vortices. This hinders accurate measurement by the stress probe, affecting the meter's performance. Furthermore, even if the flow direction indicator is installed correctly, workers may still install the meter backwards during installation, causing the generator and steam flow to be opposite. Simultaneously, the stress probe will be located upstream of the generator, preventing it from measuring based on vortices and further affecting the meter's performance.

[0005] When the generator is installed in the opposite direction to the steam flow, or when the stress probe is located upstream of the generator, the generator cannot effectively measure the steam. In this case, the instrument needs to be disassembled and reinstalled to ensure that the generator is installed in the same direction as the steam flow and that the stress probe is located downstream of the generator. When disassembling the instrument, the pipeline needs to be shut down, depressurized, and vented before the entire instrument can be disassembled and reassembled. The disassembly and reassembly process is not only cumbersome but also involves a large workload, high labor intensity, long duration, and is time-consuming and labor-intensive. It also has a significant impact on the normal operation of the system. Summary of the Invention

[0006] To address the aforementioned technical problems, this application provides a steam vortex meter with adjustable generator position and direction. By replacing the connection between the generator and the meter body with a detachable one, the installation position and direction of the generator can be adjusted within the meter body as needed. Based on the steam flow direction within the meter body, the generator is installed in the upstream mounting slot corresponding to the stress probe, enabling the steam vortex meter to operate normally. Compared to the traditional method where the generator installation direction is opposite to the steam flow direction within the meter body, requiring the entire steam 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.

The generator is installed in the mounting groove upstream of the stress probe; The stationary end cap is fixedly connected to the bottom of the generator, is located in the first mounting groove and is detachably connected and fixed to the tube wall of the meter body, and is used to adjust the direction of the generator in the meter body; The moving end cap is inserted into the second mounting groove and is detachably connected and fixed to the wall of the meter body tube, and is detachably connected to the top of the generator body to fix the top of the generator body; A static sealing plug is inserted into the first mounting groove downstream of the stress probe to seal the first mounting groove downstream of the stress probe. The dynamic sealing head is inserted into the second mounting groove downstream of the stress probe to seal the second mounting groove downstream of the stress probe.

[0008] Preferably, a first sealing gasket for sealing is provided between the stress probe and the body.

[0009] Preferably, both the stationary end cap and the moving end cap are provided with flow direction markings.

[0010] 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.

[0015] 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, allowing the installation position and direction of the generator to be adjusted within the meter body as needed. Based on the steam flow direction within the meter body, the generator is installed in the upstream mounting slot corresponding to the stress probe, enabling the steam vortex meter to operate normally.

[0022] The present application will be further described in detail below with reference to the accompanying drawings.

[0023] This application discloses a steam vortex instrument with adjustable generator position and direction.

[0024] Reference Figures 1 to 3 The steam vortex instrument includes a body 11, a head 12, a stress probe 13, a mounting plate 14, a generator 15, a stationary end cover 16, a moving end cover 17, a stationary sealing plug 18, and a moving sealing plug 19.

[0025] The two ends of the body 11 are used to connect to the pipe flange.

[0026] The meter head 12 is installed and fixed on the top of the meter body 11. Specifically, in this embodiment, a connecting plate 20 is installed between the meter head 12 and the meter body 11. The connecting plate 20 is fixed to the top of the meter body 11 by bolt connection, and the meter head 12 is fixed to the upper end of the connecting plate 20 by bolt connection.

[0027] Reference Figure 2 The stress probe 13 is installed on the meter body 11. Specifically, the meter body 11 has a probe slot 111 for installing the stress probe 13. The stress probe 13 is installed in the probe slot 111, and the lower half of the stress probe 13 is suspended in the meter body 11 for measuring the parameters of the steam. The stress probe 13 is electrically connected to the meter head 12 via a wire.

[0028] In order to improve the sealing between the stress probe 13 and the body 11, a first sealing gasket 21 is installed between the stress probe 13 and the body 11. The first sealing gasket 21 is sleeved on the stress probe 13 and is located in the probe groove 111.

[0029] Reference Figure 2 and Figure 3The fixing plate 14 is used to install and fix the stress probe 13 onto the meter body 11. Specifically, the fixing plate 14 is sleeved on the top of the stress probe 13, and the fixing plate 14 and the meter body 11 are detachably connected and fixed by bolts. When installing or removing the stress probe 13, the fixing plate 14 is removed and installed, and then the stress probe 13 is taken out from the probe slot 111 or installed. Furthermore, due to the limited space at the top of the meter body 11, the fixing plate 14 can be used to install and fix the stress probe 13 below the connecting plate 20, that is, the fixing plate 14 is located between the connecting plate 20 and the meter body 11. When it is necessary to remove or install the fixing plate 14, the connecting plate 20 must first be removed from the meter body 11, then the fixing plate 14 must be removed and installed, and finally the connecting plate 20 must be installed and fixed onto the meter body 11.

[0030] Refer to Figure 2 and Figure 3 The watch body 11 has two sets of mounting slots. These two sets of mounting slots are distributed on both sides of the stress probe 13 along the axial direction of the watch body 11. Each set of mounting slots includes a first mounting slot 112 and a second mounting slot 113. The first mounting slot 112 is located at the bottom of the watch body 11, and the second mounting slot 113 is located at the top of the watch body 11.

[0031] The generator 15 is inserted into the mounting groove and located inside the meter body 11. During use, the generator 15 needs to be adjusted in direction within the meter body 11 according to the direction of use. The generator 15 is used to generate vortices inside the meter body 11. During use, the installation position of the generator 15 needs to be selected according to the steam flow direction inside the meter body 11. Specifically, the generator 15 needs to be installed in the set of mounting grooves upstream of the stress probe 13.

[0032] Reference Figure 2 and Figure 3 The stationary end cap 16 is fixedly connected to the bottom of the generator 15, wherein the fixed connection can be achieved by welding or integral molding. The stationary end cap 16 is installed into the first mounting groove 112, and the stationary end cap 16 is fixedly connected to the lower end of the tube wall of the meter body 11 by a detachable connection, wherein the detachable connection includes, but is not limited to, plug-in, snap-fit, and bolt connection. In this embodiment, the stationary end cap 16 is fixedly connected to the tube wall of the meter body 11 by bolt connection.

[0033] To improve the sealing between the stationary end cover 16 and the instrument body 11, a first sealing ring 22 is provided between the stationary end cover 16 and the instrument body 11. The first sealing ring 22 can be an O-ring. The first sealing ring 22 is fitted onto the stationary end cover 16. In order to improve the sealing effect, two first sealing rings 22 are selected, and the two first sealing rings 22 are respectively installed in different sealing grooves on the stationary end cover 16.

[0034] Reference Figure 2 and Figure 3 The moving end cap 17 is installed into the second mounting groove 113, and the moving end cap 17 is detachably connected and fixed to the upper end of the tube wall of the meter body 11. The detachable connection and fixing includes, but is not limited to, plug-in, snap-fit, and bolt connection. In this embodiment, the moving end cap 17 is connected and fixed to the tube wall of the meter body 11 by bolt connection.

[0035] Reference Figure 3 and Figure 4 The moving end cap 17 and the top of the generator 15 are also detachably connected and fixed. The detachable connection and fixing includes, but is not limited to, plugging and snapping. Specifically, in this embodiment, the moving end cap 17 has an isosceles trapezoidal groove 171 with the same shape as the bottom surface of the generator 15 on the side facing the generator 15. The size and shape of the groove 171 are the same as the size and shape of the generator 15. During installation, the top of the generator 15 is inserted into the groove 171 at the bottom of the moving end cap 17 to fix the top of the generator 15 and reduce the vibration of the generator 15 when it is subjected to impact.

[0036] To improve the sealing between the moving end cover 17 and the watch body 11, a second sealing ring 23 is provided between the moving end cover 17 and the watch body 11. The second sealing ring 23 can be an O-ring. The second sealing ring 23 is fitted onto the moving end cover 17. In order to improve the sealing effect, two second sealing rings 23 are selected, and the two second sealing rings 23 are respectively installed in different sealing grooves on the moving end cover 17.

[0037] Reference Figure 2 and Figure 3 Since the generator 15 needs to be located upstream of the stress probe 13, the generator 15, the stationary end cap 16 and the moving end cap 17 need to be installed in the mounting groove on the upstream side of the stress probe 13 according to the actual use, so as to utilize the steam generated by the generator 15 during use to generate vortices, thereby facilitating the stress probe 13 to perform measurements.

[0038] Meanwhile, in order to facilitate the staff to identify the installation direction of the generator 15, both the stationary end cover 16 and the moving end cover 17 are provided with flow direction markings 24 indicating the installation direction of the generator 15 and the steam flow direction inside the body 11.

[0039] Reference Figure 2 and Figure 3 The static sealing plug 18 and the dynamic sealing plug 19 need to be installed in the set of mounting slots downstream of the stress probe 13. Specifically, the static sealing plug 18 is installed in the first mounting slot 112 downstream of the stress probe 13. The static sealing plug 18 is used to seal the first mounting slot 112 downstream of the stress probe 13.

[0040] To improve the sealing performance between the static sealing plug 18 and the gauge body 11, a third sealing ring 25 is provided between the static sealing plug 18 and the gauge body 11. The third sealing ring 25 can be an O-ring. The third sealing ring 25 is fitted onto the static sealing plug 18. In order to improve the sealing effect, two third sealing rings 25 are selected, and the two third sealing rings 25 are respectively installed in different sealing grooves on the static sealing plug 18.

[0041] Reference Figure 2 and Figure 3 The dynamic sealing head 19 is installed into the second mounting groove 113 downstream of the stress probe 13. The dynamic sealing head 19 is used to seal the second mounting groove 113 downstream of the stress probe 13.

[0042] To improve the sealing performance between the dynamic sealing plug 19 and the gauge body 11, a fourth sealing ring 26 is provided between the dynamic sealing plug 19 and the gauge body 11. The fourth sealing ring 26 can be an O-ring. The fourth sealing ring 26 is fitted onto the dynamic sealing plug 19. In order to improve the sealing effect, two fourth sealing rings 26 are selected, and the two fourth sealing rings 26 are respectively installed in different sealing grooves on the dynamic sealing plug 19.

[0043] When the instrument leaves the factory, the staff first installs the stress probe 13 into the probe slot 111 and fixes it with the fixing plate 14. Then, the connecting plate 20 and the meter head 12 are installed on the meter body 11. The generator 15, the stationary end cover 16 and the moving end cover 17 can be installed in any one set of mounting slots, and the flow direction mark 24 is pointed to the stress probe 13. At the same time, the stationary sealing plug 18 and the moving sealing plug 19 are installed in another set of mounting slots.

[0044] In use, the instrument is installed on the pipeline according to the direction of steam flow in the pipeline, and the flow direction mark 24 is aligned with the direction of steam flow in the instrument body 11, so that the stress probe 13 on the instrument can measure the parameters of the steam.

[0045] After the instrument is installed, if it is found that the position of the generator 15 of the steam vortex instrument is reversed, regardless of whether the direction of the generator 15 is correct, the valve groups on both sides of the steam vortex instrument must be closed, and the instrument should be depressurized and cooled down. Then, the stationary end cover 16 and the moving end cover 17 should be removed from the instrument body 11, and the stationary sealing plug 18 and the moving sealing plug 19 should be removed from the instrument body 11. Then, the positions of the stationary end cover 16 and the moving end cover 17 and the positions of the stationary sealing plug 18 and the moving sealing plug 19 should be swapped, and the direction of the generator 15 should be adjusted so that the generator 15 is located upstream of the stress probe 13 and the direction of the generator 15 is consistent with the flow direction of the steam in the pipeline. To further reduce the workload when changing the position of the generator 15, the moving seal plug 19 can be configured to have the same structure as the moving end cover 17. When assembling the instrument, the groove on the moving seal plug 19 can be aligned in the opposite direction to the groove 171 on the moving end cover 17. In this way, when changing the position of the generator 15, only the positions of the stationary end cover 16 and the stationary seal plug 18 need to be adjusted.

[0046] After the instrument is installed, if it is found that the installation direction of the generator 15 of the steam vortex instrument is opposite to the steam flow direction in the instrument body 11, the valve groups on both sides of the steam vortex instrument should be closed, and the instrument should be depressurized and cooled down. Then, the stationary end cover 16 and the moving end cover 17 should be removed from the instrument body 11, the direction of the generator 15 should be adjusted, and then the stationary end cover 16 and the moving end cover 17 should be reinstalled on the instrument body 11 so that the direction of the generator 15 is consistent with the steam flow direction in the pipeline. Compared to traditional methods where the generator 15 needs to be installed backwards or in the opposite direction to the steam flow in the meter body 11, requiring the entire steam vortex meter to be removed from the pipeline and reinstalled, this instrument only requires readjusting the installation position and / or direction of the generator 15 on the meter body 11 so that the generator 15 is located upstream of the stress probe 13 and its direction is consistent with the steam flow in the pipeline. This greatly reduces the workload and labor intensity, and has the advantages of fast replacement speed, high efficiency, and time and labor saving.

[0047] 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.
