A Lined Ultrasonic Vortex Instrument Technical Field

[0001] This application relates to lined ultrasonic vortex instrumentation devices, and more particularly to a lined ultrasonic vortex instrumentation device. Background Technology

[0002] Lined ultrasonic vortex meters are a common type of fluid measurement instrument. Currently, among the most common heat and flow meters based on velocity principles on the market, apart from some electromagnetic instruments, lining structure designs are rarely used. As the application scenarios of instruments expand, conventional instruments without lining structures have gradually shown some shortcomings in field applications. For example, the use of exposed, pre-embedded, or conduit-driven wiring methods for ultrasonic transducers not only makes the wiring susceptible to damage from the external environment, but also increases the breakage rate due to exposed wiring. Summary of the Invention

[0003] To address the aforementioned technical problems, this application provides a lined ultrasonic vortex instrument. By lining the traditional ultrasonic vortex instrument and placing the connecting wires within the channel between the lined pipe and the instrument body, the connecting wires are changed from being exposed to being routed internally, thus solving the problem of exposed connecting wires and reducing the breakage rate of the connecting wires.

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] This application discloses a lined ultrasonic vortex instrument.

[0031] Referring to Figures 1 and 2, the ultrasonic vortex instrument includes a body 11, an end cap 12, an inner liner pipe 13, a transducer assembly 14, a meter head 15, and a connecting line 16.

[0032] Referring to Figures 2 and 3, the body 11 is a pipe with flanges at both ends, which is used as an external pipe.

[0033] There are two end caps 12, and the two end caps 12 are detachably connected and fixed to the inside of both ends of the watch body 11 in the axial direction. The detachable connection includes, but is not limited to, plug-in, snap-in, threaded connection and bolt connection. In this embodiment, the end caps 12 are installed on the watch body 11 by threaded connection.

[0034] The two ends of the inner lining pipe 13 are respectively installed on the two end caps 12, and the inner lining pipe 13 is located inside the watch body 11. At the same time, a channel is formed between the inner lining pipe 13 and the watch body 11. A sound-emitting body 131 is attached to the inner lining pipe 13 along the vertical direction.

[0035] Referring to Figures 2 and 3, the end cap 12 also has a reducing diameter inside, and the inner diameter of the connection between the end cap 12 and the inner lining pipe 13 is the same as the inner diameter of the inner lining pipe 13. Furthermore, the inner diameter of the end cap 12 increases with the distance from the inner lining pipe 13. Simultaneously, by setting a reducing diameter inside the end cap 12, the requirement for a shorter straight pipe section during instrument installation in the field can be reduced. Traditional instruments require a relatively long straight pipe section, but by setting the reducing diameter structure inside the end cap 12, the required straight pipe section distance for instrument installation is greatly shortened, making it suitable for installation environments with shorter straight pipe sections.

[0036] Specifically, a first groove 121 is provided on the side end of the end cap 12 near the inner lining pipe 13, and a first sealing ring 17 is placed in the first groove 121. A first protrusion 132 is formed on the side end of the inner lining pipe 13 near the end cap 12. During installation, the first protrusion 132 is installed in the first groove 121, and the first sealing ring 17 is located between the inner lining pipe 13 and the end cap 12, thereby sealing the end cap 12 and the inner lining pipe 13 to prevent fluid from seeping into the channel between the inner lining pipe 13 and the body 11.

[0037] Referring to Figures 2 and 3, a second groove 111 is provided on the flange of the body 11, and a second sealing ring 18 is placed in the second groove 111. The side end of the end cap 12 abuts against the flange of the body 11. The second sealing ring 18 is located between the flange of the body 11 and the end cap 12, thereby sealing the end cap 12 and the body 11 to prevent fluid from seeping into the channel between the inner lining pipe 13 and the body 11.

[0038] The transducer assembly 14 is detachably connected and fixed to the inner lining pipe 13. The detachable connection includes, but is not limited to, plug-in, snap-fit, and threaded connection. In this embodiment, the transducer assembly 14 is installed on the inner lining pipe 13 by bolt connection. There are two sets of transducer assemblies 14, which are located on both sides of the inner lining pipe 13 in the circumferential direction.

[0039] Referring to Figures 2 and 4, specifically, the transducer assembly 14 includes a mounting base 141, a transducer 142, a third sealing ring 143, a fourth sealing ring 144, and a pressure wire 145. The mounting base 141 is threaded onto the wall of the inner liner pipe 13. The mounting base 141 is used to mount and place the transducer 142, which can be directly placed inside the mounting base 141. A groove is formed in the wall of the inner liner pipe 13, and the third sealing ring 143 can be directly placed in this groove, sealing the connection between the mounting base 141 and the inner liner pipe 13. The fourth sealing ring 144 is sleeved on the transducer 142 and is installed into the mounting base 141 along with the transducer 142, sealing the connection between the transducer 142 and the mounting base 141. The pressure wire 145 is installed on the mounting base 141 by means of a threaded connection. The pressure wire 145 is used to install and fix the transducer 142 in the mounting base 141.

[0040] Referring to Figures 2 and 3, a top opening 112 is provided on the top of the watch body 11, and the watch head 15 is installed and fixed to the top of the watch body 11 by means of bolt connection, and the watch head 15 covers the top opening 112 on the watch body 11.

[0041] The connecting wire 16 is a wire used to connect the meter head 15 and the transducer 142. The two ends of the connecting wire 16 are electrically connected to the meter head 15 and the transducer 142 respectively, and the connecting wire 16 passes through the channel between the inner lining pipe 13 and the meter body 11.

[0042] To facilitate future maintenance and replacement of the transducer 142 and connecting wires 16, a side opening 113 is provided on the side end of the meter body 11. This side opening 113 is located on the inner lining pipe 13 where the transducer assembly 14 is installed, allowing maintenance personnel to easily disassemble and assemble the transducer assembly 14. A cover plate 19 is also bolted to the meter body 11, covering the side opening 113. An O-ring seal is also provided between the cover plate 19 and the meter body 11 to ensure a tight seal.

[0043] Furthermore, referring to Figures 2 and 3, a drain hole 114 is provided at the bottom of the meter body 11, and a drain plate 20 is installed at the bottom of the meter body 11. The drain plate 20 is installed on the meter body 11 by bolt connection, and an O-ring is installed between the drain plate 20 and the meter body 11.

[0044] In this embodiment, the connecting wire 16 between the meter head 15 and the transducer 142 is placed in the channel between the inner lining pipe 13 and the meter body 11, so that the connecting wire 16 is changed from the traditional exposed method to the internal wiring method, which solves the problem of the connecting wire 16 being exposed and reduces the damage rate of the connecting wire 16.

[0045] Furthermore, since traditional ultrasonic vortex instruments are integral, the entire instrument needs to be replaced after a malfunction or damage. In contrast, this application designs the ultrasonic vortex instrument as a composite of multiple internal components, allowing individual components to be replaced when some are damaged, thus reducing replacement costs. At the same time, by designing the integral structure as a composite of multiple components, the materials of each component can be selected to maximize their service life and extend the overall lifespan of the ultrasonic vortex instrument.

[0046] 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.
