Description

Technical Field

[0001] This application relates to the field of pipeline flow measurement technology, and more specifically, to a carrier device for an ultrasonic flow meter. Background Technology

[0002] Currently, clamp-on ultrasonic flow meters are commonly used to measure the medium inside pipes. These flow meters are installed on the outer wall of the pipe for measurement. However, the refractive index of the pipe wall and the medium inside the pipe are different. As ultrasonic waves refract when passing through different media, it is impossible to ensure a perfect correspondence between ultrasonic flow meters. This results in unstable ultrasonic signal reception and inaccurate measurement results.

[0003] In conclusion, improving the accuracy of ultrasonic flow meter measurements is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a carrier device for an ultrasonic flow meter to improve the accuracy of ultrasonic flow meter measurements.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A support device for an ultrasonic flow meter is provided for connecting a pipeline and an ultrasonic flow meter. The support device includes an integrally formed mounting part and a support part. The pipeline wall has an opening. The mounting part is fixedly connected to the opening in the pipeline wall. The support part is detachably connected to the ultrasonic flow meter. The support part extends through the mounting part, so that the support part has a first end that penetrates into the pipeline and a second end that is located outside the pipeline. The first end of the support part has an end face that forms a pressure-bearing boundary with the pipeline wall. The support part has a cylindrical structure, and the axis of the support part is collinear with the axis of the ultrasonic flow meter. The end face of the first end is perpendicular to the axis of the support part.

[0007] In some embodiments, a sealing plate is fixedly connected inside the support portion. The sealing plate is the end face of the first end of the support portion. The sealing plate is arranged radially along the support portion so that the sealing plate is perpendicular to the axis of the ultrasonic flow meter, and the sealing plate is close to the first end of the support portion.

[0008] In some embodiments, the mounting portion has an arc-shaped structure, and the arc of the mounting portion is adapted to the pipe wall so that the mounting portion is sealed and welded to the opening position of the pipe wall.

[0009] In some embodiments, the thickness of the mounting portion is the same as the thickness of the pipe wall.

[0010] In some embodiments, the projection surface of the mounting portion is circular, and the opening in the pipe wall is a circular hole that coincides with the projection surface of the mounting portion; or, the projection surface of the mounting portion is square, and the opening in the pipe wall is a square hole that coincides with the projection surface of the mounting portion.

[0011] In some embodiments, there is an angle between the axis of the support portion and the radial direction of the mounting portion.

[0012] In some embodiments, the second end of the support portion is provided with a thread so that the support portion is threadedly engaged with the ultrasonic flow meter; or, the second end of the support portion is provided with a rubber pad so that the support portion is pressed tightly against the ultrasonic flow meter.

[0013] In some embodiments, the support device includes two devices, which are disposed at both ends of the pipe in the radial direction; the axes of the two support portions of the two support devices are collinear, and the axis of the support portion has an angle with the radial direction of the pipe.

[0014] The ultrasonic flow meter carrier device provided in this application is used to connect a pipeline and an ultrasonic flow meter. The carrier device includes an integrally formed mounting part and a carrier part. The mounting part is fixedly connected to an opening in the pipeline wall to install the carrier device on the pipeline, and the ultrasonic flow meter is installed through the carrier part for subsequent measurement. The carrier part is disposed through the mounting part, so that the carrier part has a first end that penetrates into the pipeline and a second end that is located outside the pipeline. The end face of the first end of the carrier part and the inner wall of the pipeline together form a pressure-bearing boundary to ensure normal flow of the medium in the pipeline. The carrier part has a cylindrical structure and its axis is collinear with the axis of the ultrasonic flow meter. The end face of the first end of the carrier part is perpendicular to the axis of the carrier part. In this way, by installing the ultrasonic flow meter on the carrier part, since the carrier part has a first end that penetrates into the pipeline, the ultrasonic signals emitted and received by the ultrasonic flow meter will not pass obliquely through the pipeline wall but will be perpendicular to the end face of the first end of the carrier part that penetrates into the pipeline. This reduces the refraction of ultrasonic signals, so that the ultrasonic signals transmitted between the ultrasonic flow meters can be received more accurately, thereby improving the accuracy of the ultrasonic flow meter measurement.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The terminology used in the following embodiments is for the purpose of describing specific embodiments only and is not intended to be a limitation of this application. As used in the specification and appended claims of this application, the singular expressions "a," "an," "the," "the," "the," and "this" are intended to also include expressions such as "one or more," unless the context clearly indicates otherwise.

[0028] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0029] The "multiple" mentioned in the embodiments of this application refers to two or more. It should be noted that in the description of the embodiments of this application, terms such as "first" and "second" are used only for the purpose of distinguishing descriptions and should not be construed as indicating or implying relative importance, nor should they be construed as indicating or implying order.

[0030] The terms "parallel" and "perpendicular" used in this application refer to "basically parallel" and "basically perpendicular" in practical operation. "Basically parallel" can be understood as parallelism with a certain degree of error, and similarly, "basically perpendicular" can be understood as perpendicularity with a certain degree of error.

[0031] like Figure 1 As shown, in the prior art, two clamp-on ultrasonic flow meters 200 are typically fixed to the outside of the pipe wall of the pipe 300 to measure the medium inside the pipe 300. Due to the principle of the ultrasonic flow meter 200 measuring the medium flowing axially within the pipe 300, an angle is required between the axis of the ultrasonic flow meter 200 and the pipe 300 to create an incident angle between the ultrasonic signal and the pipe 300. However, when measuring media with significant temperature and pressure variations, the ultrasonic signal undergoes refraction as it passes through different media. After the ultrasonic flow meter 200 emits an ultrasonic signal, it first passes through the pipe wall at a non-perpendicular incident angle. Upon exiting the pipe wall, the ultrasonic signal is refracted due to the different refractive indices of the media within the pipe. When the medium conditions change significantly, the refraction angle may change excessively, causing the corresponding ultrasonic flow meter 200 to fail to accurately receive the ultrasonic signal, resulting in inaccurate measurement results.

[0032] Therefore, this application provides a carrier device for an ultrasonic flow meter, which improves the accuracy of ultrasonic flow meter measurements.

[0033] like Figure 2As shown in the embodiment of this application, the ultrasonic flow meter carrier device is used to connect the pipe 300 and the ultrasonic flow meter 200. The carrier device includes an integrally formed mounting part 110 and a carrier part 120. An opening is provided in the pipe wall of the pipe 300 where the ultrasonic flow meter 200 needs to be installed. The mounting part 110 is fixedly connected to the opening position of the pipe wall of the pipe 300 to install the carrier device on the pipe. The carrier part 120 is used to detachably connect the ultrasonic flow meter 200 so as to install the ultrasonic flow meter 200 for subsequent measurement operations. The carrier part 120 penetrates the mounting part 110, so that the carrier part 120 has a first end that penetrates into the pipe 300 and a second end that is located outside the pipe 300. The first end of the carrier part 120 has an end face that forms a pressure-bearing boundary together with the pipe wall of the pipe 300, so that the pipe 300 can withstand pressure. The medium inside the pipe 300 flows normally, and the support part 120 has a cylindrical structure. The axis of the cylindrical support part 120 is collinear with the axis of the ultrasonic flow meter 200, and the end face of the first end of the support part is perpendicular to the axis of the support part. In this way, when it is necessary to measure the medium inside the pipe 300, by installing the ultrasonic flow meter 200 at the second end of the support part 120, since the support part 120 has a first end that penetrates into the inside of the pipe 300, the ultrasonic signals emitted and received by the ultrasonic flow meter 200 will not obliquely pass through the pipe wall of the pipe 300, but will be perpendicular to the end face of the first end of the support part 120 that penetrates into the inside of the pipe 300. This reduces the refraction phenomenon of ultrasonic signals, so that the ultrasonic signals transmitted between the ultrasonic flow meters 200 can be accurately received, thereby improving the measurement accuracy of the ultrasonic flow meter 200.

[0034] In actual measurement, two ultrasonic flow meters 200 are required to be set up correspondingly to receive ultrasonic signals. Therefore, the carrier device provided in this application embodiment is set up in a group, such as... Figure 1 As shown, each set of support devices includes two devices, which are arranged at both ends of the pipe 300 in the radial direction. The axes of the support parts 120 in the two support devices are collinear, so that after the ultrasonic flow meters 200 are installed on the two support parts 120 respectively, the ultrasonic signals of the two ultrasonic flow meters 200 can be accurately received. Furthermore, there is an angle between the axis of the support part 120 and the radial direction of the pipe 300, so that the ultrasonic signal emitted by the ultrasonic flow meter 200 has an angle with the pipe 300, which satisfies the measurement principle of the ultrasonic flow meter 200 and ensures the accuracy of the ultrasonic flow meter 200 measurement.

[0035] Since the pipe 300 is fixedly connected to the mounting part 110 after the hole is opened, in order to reduce the leakage of the medium inside the pipe 300, such as Figure 3As shown, a sealing plate 121 is fixedly connected inside the support portion 120. The sealing plate 121 is the first end face of the support portion 120. The sealing plate 121 is arranged radially along the support portion 120 so that the sealing plate 121 is perpendicular to the axis of the ultrasonic flow meter 200. This ensures that the ultrasonic signal emitted by the ultrasonic flow meter 200 is perpendicular to the sealing plate 121, preventing refraction of the ultrasonic signal as it passes through the sealing plate 121. This ensures that the emission path of the ultrasonic signal extends along the axis of the ultrasonic flow meter 200, thereby improving the accuracy of ultrasonic signal reception and measurement accuracy.

[0036] In order to provide installation space for the ultrasonic flow meter 200, the sealing plate 121 is disposed near the first end of the bearing portion 120 that penetrates into the pipe 300 to seal the medium within the pipe 300.

[0037] To ensure a sealed connection between the mounting section 110 and the pipe 300, such as Figures 4-5 As shown, the mounting part 110 has an arc-shaped structure, and the curvature of the mounting part 110 is adapted to the pipe wall of the pipe 300. That is, after the mounting part 110 is sealed and welded to the pipe 300, it can form an integral part with the pipe 300, so as to realize the overall installation of the bearing device onto the pipe 300 to ensure the normal operation of the pipe 300.

[0038] Since the mounting part 110 is welded to the pipe 300 after the hole is opened, in order to ensure the overall strength of the pipe 300, the thickness of the mounting part 110 is the same as the pipe wall thickness of the pipe 300, so as to ensure the integrity of the pipe 300.

[0039] It should be noted that the specific values ​​of the curvature and thickness of the mounting part 110 can be adjusted according to the actual pipe 300 to be installed, so as to ensure that the mounting part 110 is compatible with the pipe 300. This application embodiment does not limit this.

[0040] In some embodiments, such as Figure 6 As shown, the projection surface of the mounting part 110 is circular. In order to correspond with the mounting part 110, the opening in the pipe wall of the pipe 300 is a circular hole that is consistent with the projection surface, so as to ensure the sealing welding between the mounting part 110 and the pipe 300.

[0041] In some other embodiments, the projection surface of the mounting part 110 may also be square, and the pipe wall opening of the pipe 300 may be a square hole consistent with the projection surface. This application does not limit this aspect.

[0042] like Figure 2As shown, there is an angle between the axis of the support part 120 and the radial direction of the mounting part 110. Since the mounting part 110 is welded to the pipe 300, after the ultrasonic flow meter 200 is installed through the support part 120, the ultrasonic signal of the ultrasonic flow meter 200 can have an angle with the radial direction of the pipe 300, so as to satisfy the measurement principle of the ultrasonic flow meter 200 and ensure the accuracy of the measurement.

[0043] To facilitate the connection between the support portion 120 and the ultrasonic flow meter 200, in some embodiments, the second end of the support portion 120 is provided with a thread so that the ultrasonic flow meter 200 and the support portion 120 are threadedly connected. The ultrasonic flow meter 200 can be disassembled and assembled as needed to improve the convenience of the measurement process.

[0044] In some other embodiments, a rubber pad can be provided inside the second end of the support portion 120 to press the ultrasonic flow meter 200 into the support portion 120, so that the ultrasonic flow meter 200 can be disassembled and assembled as needed to improve the convenience of the measurement process.

[0045] In the operation of the ultrasonic flow meter carrier device provided in this application embodiment, firstly, a hole is made in the pipe wall of the pipe 300 corresponding to the projection shape of the mounting part 110, and the mounting part 110 is sealed and welded to the hole position so that the mounting part 110 and the pipe 300 are welded together. Then, the ultrasonic flow meter 200 is installed in the carrier part 120. Since the carrier part 120 has a first end that penetrates into the inside of the pipe 300, and the ultrasonic signals emitted and received by the ultrasonic flow meter 200 are perpendicular to the sealing plate 121, the ultrasonic signals do not refract during the process of passing through the sealing plate 121, so that the ultrasonic signals emitted by the ultrasonic flow meter 200 can be more accurately received, thereby improving the measurement accuracy of the ultrasonic flow meter 200.

[0046] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
