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 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 generator to generate vortices inside the meter body, and then install a stress probe for measurement downstream of the generator. The stress probe measures the vortices generated after passing through the generator. The downstream of the generator is the rear end along the flow direction of the generator, that is, the steam first flows through the generator to generate vortices. The stress probe measures the steam parameters based on 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 an adjustable generator direction. By replacing the connection between the generator and the meter body with a detachable one, the installation direction of the generator can be adjusted within the meter body as needed. Based on the generator's installation direction, a stress probe is installed into the corresponding mounting slot, enabling the steam vortex meter to operate normally. Compared to the traditional method where the generator's 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.

[0007] This application provides a steam vortex meter with adjustable generator direction, which adopts the following technical solution: A steam vortex meter 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 gauge tube, and is also detachably connected to the top of the generator, for fixing the top of the generator; Two mounting slots are distributed on both sides of the generator along the axial direction of the dial body; The stress probe is inserted into a mounting groove and suspended inside the meter body, located downstream of the generator and electrically connected to the meter head; A sealing head, inserted into another mounting groove, is used to seal the mounting groove; and The mounting plate, detachably connected to the top of the meter body, is used to fix the stress probe or sealing head to the meter body.

[0008] Preferably, both the stationary end cap and the moving end cap are provided with flow direction markings.

[0012] Preferably, a first sealing gasket for sealing is provided between the stress probe and the body.

[0013] Preferably, a second sealing gasket for sealing is provided between the sealing head and the body.

[0014] 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 direction of the generator to be adjusted within the meter body as needed. Based on the installation direction of the generator, the stress probe is installed into the corresponding mounting slot, enabling the steam vortex meter to work normally. Compared to the traditional method where the installation direction of the generator 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 greatly reduces workload and labor intensity, and offers faster replacement speed, shorter time, and higher efficiency.

[0020] The present application will be further described in detail below with reference to the accompanying drawings.

[0021] This application discloses a steam vortex meter with adjustable generator direction.

[0022] Reference Figure 1 and Figure 2 The steam vortex instrument includes a body 11, a head 12, a generator 13, a stationary end cover 14, a moving end cover 15, a stress probe 16, a plugging head 17, and a fixing plate 18.

[0023] The two ends of the body 11 are used to connect to the pipe flange.

[0024] The meter head 12 is installed and fixed on the top of the meter body 11. Specifically, in this embodiment, a connecting plate 19 is installed between the meter head 12 and the meter body 11. The connecting plate 19 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 19 by bolt connection.

[0025] Reference Figure 1 and Figure 2 The generator 13 is inserted inside the body 11 and is used to generate vortices inside the body 11.

[0026] Specifically, the stationary end cap 14 is fixedly connected to the bottom of the generator 13, wherein the fixed connection can be achieved by welding or integral molding. The stationary end cap 14 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 14 is fixedly connected to the tube wall of the meter body 11 by bolt connection.

[0027] To improve the sealing between the stationary end cover 14 and the instrument body 11, a first sealing ring 20 is provided between the stationary end cover 14 and the instrument body 11. The first sealing ring 20 can be an O-ring. The first sealing ring 20 is fitted onto the stationary end cover 14. In order to improve the sealing effect, two first sealing rings 20 are selected, and the two first sealing rings 20 are respectively installed in different sealing grooves on the stationary end cover 14.

[0028] Reference Figure 2 and Figure 3 The moving end cap 15 is detachably connected to the upper end of the tube wall of the meter body 11. This detachable connection includes, but is not limited to, plug-in, snap-fit, and bolt connections. In this embodiment, the moving end cap 15 is connected to the tube wall of the meter body 11 by bolts.

[0029] The moving end cap 15 and the top of the generator 13 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 15 has an isosceles trapezoidal groove 151 with the same shape as the bottom surface of the generator 13 on the side facing the generator 13. The size and shape of the groove 151 are the same as the size and shape of the generator 13. During installation, the top of the generator 13 is inserted into the groove 151 at the bottom of the moving end cap 15 to fix the top of the generator 13 and reduce the vibration of the generator 13 when it is subjected to impact.

[0030] To improve the sealing between the moving end cover 15 and the watch body 11, a second sealing ring 21 is provided between the moving end cover 15 and the watch body 11. The second sealing ring 21 can be an O-ring. The second sealing ring 21 is fitted onto the moving end cover 15. In order to improve the sealing effect, two second sealing rings 21 are selected, and the two second sealing rings 21 are respectively installed in different sealing grooves on the moving end cover 15.

[0031] Reference Figure 2 and Figure 3 In order to facilitate the staff to identify the installation direction of the generator 13, both the stationary end cover 14 and the moving end cover 15 are provided with flow direction markings 22 indicating the installation direction of the generator 13 and the steam flow direction inside the body 11.

[0032] Reference Figure 2 The watch body 11 has two mounting slots 111, which are distributed on both sides of the generator 13 along the axial direction of the watch body 11.

[0033] The stress probe 16 is installed in the mounting groove 111. When in use, the stress probe 16 is installed in the corresponding mounting groove 111 based on the flow direction of the steam in the body 11, or the mounting groove 111 in the rear or downstream direction of the generator 13 is selected for installation based on the installation direction of the generator 13.

[0034] After the stress probe 16 is installed in the mounting groove 111 on the meter body 11, the lower half of the stress probe 16 is suspended in the meter body 11 for measuring the parameters of steam. The stress probe 16 is electrically connected to the meter head 12 via a wire.

[0035] Reference Figure 2 In order to improve the sealing between the stress probe 16 and the body 11, a first sealing gasket 23 is installed between the stress probe 16 and the body 11. The first sealing gasket 23 is sleeved on the stress probe 16 and is located in the mounting groove 111.

[0036] After the stress probe 16 is installed into one of the mounting slots 111, the sealing head 17 is installed into the other empty mounting slot 111 so that the sealing head 17 seals the empty mounting slot 111.

[0037] Reference Figure 2 In order to improve the sealing performance between the sealing head 17 and the meter body 11, a second sealing gasket 24 is installed between the sealing head 17 and the meter body 11. The second sealing gasket 24 is sleeved on the sealing head 17, and similarly, the second sealing gasket 24 is located in the mounting groove 111.

[0038] The fixing plate 18 is used to fix the stress probe 16 or the sealing head 17 into the mounting groove 111. Two fixing plates 18 are used, one for fixing the stress probe 16 and the other for fixing the sealing head 17. The fixing plate 18 is detachably connected to the top of the meter body 11, wherein the detachable connection includes, but is not limited to, plug-in, snap-fit, bolt connection, or threaded connection. In this embodiment, the fixing plate 18 is fixed to the top of the meter body 11 by bolts.

[0039] In use, the operator can install the generator 13 according to the flow direction marking 22 on the stationary end cover 14 or the moving end cover 15, and then install the stress probe 16 into the installation groove 111 in the downstream direction of the generator 13 and fix it with the fixing plate 18. Then, the sealing head 17 is used to seal the other installation groove 111 and the sealing head 17 is fixed with the fixing plate 18. When the staff installs the steam vortex meter, the meter can be installed on the pipeline according to the flow direction mark 22. After the installation is completed, if it is found that the direction of the generator 13 of the steam vortex meter is opposite to the steam flow direction in the meter body 11, the valve groups on both sides of the steam vortex meter need to be closed. After depressurizing and cooling the inside of the meter, the connecting plate 19 is first removed from the meter body 11. Then the moving end cover 15 and the stationary end cover 14 are removed. After adjusting the direction of the generator 13, the stationary end cover 14 and the moving end cover 15 are reinstalled and fixed on the meter body 11 so that the direction of the generator 13 is consistent with the steam flow direction in the pipeline. Next, the stress probe 16 and the plug head 17 are disassembled respectively. Then, the installation positions of the stress probe 16 and the plug head 17 are swapped, and they are re-fixed using the fixing plate 18. Finally, the connecting plate 19 is reinstalled and fixed onto the meter body 11.

[0040] Compared to the traditional method where the installation direction of the generator 13 is opposite to the steam flow direction in the meter body 11, requiring the entire steam vortex instrument to be disassembled from the pipeline and reinstalled, this method only requires readjusting the direction of the generator 13 and the position of the stress probe 16 relative to the generator 13. This greatly reduces the workload and labor intensity, and has the advantages of fast replacement speed, high efficiency, and time and labor saving.

[0041] 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.
