Description

Technical Field

[0001] This utility model relates to an integrated ultrasonic water meter pipe section structure. Background Technology

[0002] Currently, most ultrasonic water meters use a reflector installed in the center of the pipe channel to reflect the signal. A small reflector reduces the reflection area and amplitude, while a large reflector obstructs fluid flow, increases pressure loss, creates turbulence, and affects the stability of the ultrasonic signal. Existing water meters typically install the reflector in the non-neck section, thus loading flow velocity information from both inside and outside the neck, resulting in abrupt changes in area. This affects both flow stability and metering accuracy. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an integrated ultrasonic water meter pipe section structure. This structure embeds the reflector assembly within the inner pipe section, flush with the inner wall, thereby avoiding interference with fluid flow, preventing turbulence, and improving measurement accuracy.

[0004] The objective of this utility model can be achieved through the following technical solution: An integrated ultrasonic water meter pipe section structure, comprising an outer pipe section, an inner pipe section installed with its outer wall abutting against the inner wall of the outer pipe section, and a reflector assembly. One end of the outer pipe section is an inlet section, and the other end is an outlet section. A temperature measuring component is provided in the middle of the outer pipe section facing upward. The outer pipe section has two mounting pipe sections symmetrically and obliquely arranged relative to the temperature measuring component. A transducer mounting hole is provided on the mounting pipe section, and a transducer is installed in the transducer mounting hole and sealed by a potting layer, wherein:

[0005] An installation structure is provided between the inner pipe section and the outer pipe section;

[0006] The reflector assembly is embedded in the inner wall of the inner tube section and is flush with the inner wall of the inner tube section. The signal band formed by the reflector assembly and the transducer is W-shaped.

[0007] Furthermore, the inlet section and outlet section are externally threaded.

[0008] Furthermore, the bottom of the transducer is a ceramic plate and the transducer is encapsulated within the transducer mounting hole.

[0009] Furthermore, the tilt angle between the installation pipe section and the external pipe section is set according to factors such as the transducer installation distance, the internal diameter of the inner pipe section, and the required signal flight distance.

[0010] Furthermore, the temperature measuring component includes a temperature measuring hole integrally formed with the external pipe section, a copper plug installed in the temperature measuring hole, a threaded hole for threaded connection of the copper plug in the middle of the temperature measuring hole, and a sealing ring between the copper plug and the temperature measuring hole.

[0011] Furthermore, the upper inner wall of the outer pipe section is a first plane, and its upper inner wall and lower inner wall are a second plane and a third plane, respectively. The third plane has a first groove and a third groove with a distance between them. The second plane has a second groove corresponding to the temperature measuring component, and the second groove has a connecting hole and a threaded hole communicating with each other.

[0012] Furthermore, the reflective assembly includes a first reflective sheet, a second reflective sheet, and a third reflective sheet. The first reflective sheet is installed in a first groove, the second reflective sheet is installed in a second groove, and the third reflective sheet is installed in a third groove. The surfaces of the first and third reflective sheets are flush with the third plane, and the surface of the second reflective sheet is flush with the second plane. The first, second, and third reflective sheets have the same structural shape and injection holes are provided at the four corners.

[0013] Furthermore, the inner tube section is a plastic tube, and the first reflective sheet, the second reflective sheet, the third reflective sheet and the inner tube section insert are injection molded together and connected and fixed by protrusions formed through injection holes.

[0014] Furthermore, the installation structure has a guide groove on the inner wall of the outer pipe section and a guide rib on the outer wall of the inner pipe section corresponding to the guide groove, and the inner pipe section cooperates with the first plane.

[0015] Compared with the prior art, the advantages of this application are: by embedding the reflector assembly in the inner tube section and making it flush with the inner wall, it does not affect the fluid flow, does not form turbulence, and improves the measurement accuracy.

[0024] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0025] like Figure 1-7 As shown, an integrated ultrasonic water meter pipe section structure includes an outer pipe section 1, an inner pipe section 2 installed and whose outer wall is attached to the inner wall of the outer pipe section 1, and a reflector assembly. One end of the outer pipe section 1 is an inlet section 12, and the other end is an outlet section 11. A temperature measuring component is provided in the middle of the outer pipe section 1 facing upward. The outer pipe section 1 has two mounting pipe sections 13 that are symmetrically and obliquely arranged relative to the temperature measuring component. A transducer mounting hole 133 is provided on the mounting pipe section 13. A transducer 131 is installed in the transducer mounting hole 133 and sealed by a potting layer 132, wherein: the sealing performance is improved by sealing with the potting layer 132.

[0026] like Figure 2 As shown, an installation structure is provided between the inner pipe section 2 and the outer pipe section 1; the two are positioned and assembled through the installation structure.

[0027] like Figure 4 As shown, the reflector assembly is embedded in the inner wall of the inner tube section 2 and flush with the inner wall of the inner tube section 2. The signal band formed by the reflector assembly and the transducer 131 is W-shaped. The W-shaped signal has a long flight time and high signal accuracy.

[0028] Furthermore, the inlet section 12 and the outlet section 11 are externally threaded.

[0029] like Figure 4 As shown, further, the bottom of the transducer 131 is a ceramic plate 134, and the transducer 131 is encapsulated within the transducer mounting hole 133. The transducer 131 includes a housing, a ceramic plate 134 at the bottom of the housing, and other internal components. Here, the transducer 131 and other components are directly encapsulated within the transducer mounting hole 133, with the ceramic plate 134 located at the bottom of the transducer mounting hole 133.

[0030] Furthermore, the tilt angle between the installation pipe section 13 and the outer pipe section 1 is set according to factors such as the installation distance of the transducer 131, the inner diameter of the inner pipe section 2, and the required signal flight distance. This setting can find the most suitable angle for the measurement accuracy of the W-shaped signal waveform, select outer pipe sections 1 of different diameters according to the actual situation, and change the tilt angle according to factors such as the installation distance of the two transducers 131 and the required flight distance.

[0031] like Figure 4 , Figure 7 As shown. Further, the temperature measuring component includes a temperature measuring hole 14 integrally formed with the external pipe section 1, a copper plug 141 installed in the temperature measuring hole 14, a threaded hole 143 for threaded connection of the copper plug 141 in the middle of the temperature measuring hole 14, and a sealing ring 142 between the copper plug 141 and the temperature measuring hole 14.

[0032] Furthermore, the upper inner wall of the outer pipe section 1 is a first plane 21, and the upper inner wall and lower inner wall of the inner pipe section 2 are a second plane 22 and a third plane 23, respectively. The third plane 23 has a first groove 2012 and a third groove 2031 with a distance between them. The second plane 22 has a second groove 2021 corresponding to the temperature measuring component, and the second groove 2021 has a connecting hole 2022 communicating with the threaded hole 143.

[0033] The connection hole 2022 is connected to the threaded hole 143, and the heat is transferred through the copper plug 141. The temperature is measured by an external thermometer. A sealing ring 142 is set between the copper plug 141 and the temperature measuring hole 14 to enhance the sealing performance at this point.

[0034] like Figure 4-7 As shown, the reflective assembly further includes a first reflective sheet 201, a second reflective sheet 202, and a third reflective sheet 203. The first reflective sheet 201 is installed in a first groove 2012, the second reflective sheet 202 is installed in a second groove 2021, and the third reflective sheet 203 is installed in a third groove 2031. The surfaces of the first reflective sheet 201 and the third reflective sheet 203 are flush with the third plane 23, and the surface of the second reflective sheet 202 is flush with the second plane 22. The first reflective sheet 201, the second reflective sheet 202, and the third reflective sheet 203 have the same structural shape and injection holes 2011 are provided at the four corners.

[0035] Furthermore, the inner tube section 2 is a plastic tube, and the first reflective sheet 201, the second reflective sheet 202, the third reflective sheet 203 and the inner tube section 2 insert are injection molded together and connected and fixed by forming a protrusion 204 through the injection hole 2011.

[0036] By installing the first reflector 201 in the first groove 2012, the second reflector 202 in the second groove 2021, and the third reflector 203 in the third groove 2031, with the surfaces of the first reflector 201 and the third reflector 203 flush with the third plane 23, the plastic flows into the injection hole 2011 during injection molding. After injection molding, the connection between the first reflector 201, the second reflector 202, the third reflector 203 and the inner tube section 2 is strengthened by the protrusion 204. The flush setting ensures that the fluid flow is unobstructed, does not cause turbulence that affects the measurement accuracy, and has no pressure loss.

[0037] like Figure 2 As shown, further, the installation structure has a guide groove 15 on the inner wall of the outer pipe section 1, and a guide rib 24 corresponding to the guide groove 15 on the outer wall of the inner pipe section 2. The inner pipe section 2 mates with the first plane 21. The inner pipe section 2 and the outer pipe section 1 are positioned and assembled through the guide groove 15 and the guide rib 24.

[0038] This embodiment consists of an inner tube section 2 with an internal reflective sheet and an outer tube section 1, as shown below. Figure 4 As shown, the signal band formed by the reflector assembly and transducer 131 is W-shaped. The path is as follows: the signal emitted by transducer 131 located in the inlet section 12 passes through ceramic plate 134, is reflected by the first reflector 201, then to the second reflector 202, then to the third reflector 203, and finally to the transducer 132 located in the outlet section 11. The W-shape increases the signal flight time. The reflector assembly is injection molded with the inner tube section 2 using an insert injection molding method. The first reflector 201, the second reflector 202, and the third reflector 203 are flush with the second plane 22 and the third plane 23 of the inner tube section 2, respectively. All three have four injection holes 2011. When the inner pipe section 2 is injected, plastic can flow in to form a protrusion 204, which increases the firmness of the first reflector 201, the second reflector 202, the third reflector 203 and the inner pipe section 2. The inner diameter of the outer pipe section 1 and the outer diameter of the inner pipe section 2 fit together. The outer pipe section 1 has a guide groove 15 and a first plane 21. The inner pipe section 2 is set with a guide rib 24 at the corresponding position, and the first plane 21 fits in. When assembled with the plastic pipe, the plastic pipe can be positioned and assembled. There are no obstructive sharp structures inside the inner pipe section 2, so the water can flow through the pipe without obstruction and with almost no pressure loss. The ceramic plate 134 can be directly attached to the transducer mounting hole 133 of the outer pipe section 1.

[0039] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.
