Abstract

This utility model relates to the field of water conservancy engineering, specifically disclosing a pipeline structure for accurately monitoring the internal pressure of a pipeline, including a main pipeline, a ball valve, a connecting plate, and a pressure gauge. The connecting rod of the pressure gauge is designed with an extended length and external threads. This solution extends the connecting part of the pressure gauge and its matching threads, and selects a suitable ball valve with an internal straight through-type structure. Through this rational design, the sensing section of the pressure gauge can be closer to the main pipeline, thereby obtaining more accurate pressure data. During the installation of the pressure gauge, although it will be subject to water pressure resistance, the threaded connection makes it easier to screw in. During installation, some water may overflow from the threaded holes of the connecting plate; this can be easily resolved by wrapping Teflon tape around the rear section of the connecting part for sealing, and then wiping the area around the pipeline dry after installation.

Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering, and specifically relates to a pipeline structure for accurately monitoring the internal pressure of a pipeline. Background Technology

[0002] The pressure sensor core of a pressure gauge, once inserted into a pipeline, can monitor and provide real-time feedback on pressure changes in the water flow within the pipeline, helping users accurately grasp the system's operating conditions. Currently, the conventional installation method involves setting up a separate measurement loop and branch pipe on the side of the main pipeline. This solution, by adding an isolation valve, can disconnect the branch pipe from the main pipeline while the main system is running, thus facilitating pressure gauge replacement and maintenance, offering significant operational convenience. However, due to the limitations of the branch pipe structure itself, this method may introduce pressure loss, signal lag, or fluid resonance, affecting measurement accuracy and response speed. Therefore, how to install the pressure gauge more directly close to the main pipeline without compromising system safety to obtain more intuitive and dynamic pressure change information has become a technical problem worthy of in-depth research. Utility Model Content

[0003] The purpose of this utility model is to provide a pipeline structure that facilitates pressure gauge replacement and has multiple usage methods.

[0004] To achieve the above objectives, this utility model provides a pipeline structure for accurately monitoring the internal pressure of a pipeline, comprising: a main pipeline, a ball valve, a connecting plate, and a pressure gauge. The main pipeline has an opening and a flange on its side for connecting the ball valve. The connecting plate is mounted on the other end of the ball valve via the flange. A threaded hole is provided in the middle of the connecting plate. The lower part of the pressure gauge is a connecting rod, and the outer side of the connecting rod is threaded. The pressure gauge is mounted to the connecting plate via the connecting rod, and the sensing end of the pressure gauge faces the interior of the main pipeline.

[0005] As an improvement to the above solution, the length of the connecting rod and the length of the external thread are both greater than the length of the ball valve, and the outer diameter of the connecting rod is smaller than the inner diameter of the ball valve when it is in operation, so that the bottom of the connecting rod can penetrate the ball valve.

[0006] As an improvement to the above solution, the lower part of the connecting rod is marked. When the mark is exposed, it indicates that the connecting rod is disengaged from the ball valve, and the ball valve can be closed.

[0007] As an improvement to the above solution, the upper part of the connecting rod is wrapped with PTFE tape. When the connecting rod is fully screwed into the connecting plate, the PTFE tape fills and seals the upper part of the connecting rod and the screw hole of the connecting plate.

[0008] As an improvement to the above solution, a raised boss is provided at the center of the connecting plate, and a screw hole for installing the connecting rod is provided at the center of the boss.

[0009] This utility model has the following beneficial effects:

[0010] This solution extends the pressure gauge's connection section and its matching threads, and selects a compatible ball valve with an internally straight, through-type structure. This optimized design allows the pressure gauge's sensing section to be closer to the main pipeline, resulting in more accurate pressure data. While water pressure resistance may occur during installation, the threaded connection makes screwing it in effortless. Some water may overflow from the threaded holes of the connection plate during installation; this can be easily resolved by wrapping PTFE tape around the rear section of the connection and drying the surrounding pipeline after installation. Overall, this structure is relatively easy to install and operate. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] In the description of this invention, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. Where the terms "first," "second," and "third" are used for descriptive purposes and to distinguish technical features, they should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the sequential relationship of the indicated technical features.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will now be described based on its overall structure.

[0018] Reference Figures 1 to 3 This utility model discloses a pipeline structure for accurately monitoring the internal pressure of a pipeline, comprising: a main pipeline 10, a ball valve 20, a connecting plate 31, and a pressure gauge 30. The main pipeline 10 has an opening and a flange on its side for connecting the ball valve 20. The other end of the ball valve 20 is connected to the connecting plate 31 via the flange. The connecting plate 31 has a threaded hole in its center. The lower part of the pressure gauge 30 is a connecting rod 32, and the outer side of the connecting rod 32 is threaded. The pressure gauge 30 is installed to the connecting plate 31 via the connecting rod 32, and the sensing end of the pressure gauge 30 faces the interior of the main pipeline 10. In this design, the pressure gauge 30 is directly mounted on the ball valve 20, resulting in a simpler structure compared to traditional measurement circuits.

[0019] As an improvement to the above solution, the length of the connecting rod 32 and the length of its external thread are both greater than the length of the ball valve 20, and the outer diameter of the connecting rod 32 is smaller than the inner diameter of the ball valve 20 when it is in operation, so that the bottom of the connecting rod 32 can penetrate the ball valve 20. This design allows the bottom of the connecting rod 32 to be closer to the main pipe.

[0020] As an improvement to the above solution, a mark 34 is provided on the lower part of the connecting rod 32. When the mark 34 is exposed, it indicates that the connecting rod 32 is disengaged from the ball valve 20, and the ball valve 20 can be closed. With this solution, when a worker sees the mark 34, they can intuitively determine whether the ball valve 20 can be closed. Furthermore, the mark 34 can be a special color or a notch.

[0021] As an improvement to the above solution, the upper part of the connecting rod 32 is wrapped with PTFE tape. When the connecting rod 32 is fully screwed into the connecting plate 31, the PTFE tape fills and seals the upper part of the connecting rod 32 and the screw hole of the connecting plate 31, so as to achieve a tight fit between the two and prevent water leakage.

[0022] As an improvement to the above solution, a raised boss 33 is provided at the center of the connecting plate 31, and a screw hole for mounting the connecting rod 32 is provided at the center of the boss 33. By adopting the above solution, the boss 33 increases the contact area with the connecting rod 32, which helps to maintain the stability of the pressure gauge 30.

[0023] This design extends the connecting part of the pressure gauge 30 and its matching threads, and selects a compatible ball valve 20 with an internally straight through-hole structure. This optimized design allows the sensing section of the pressure gauge 30 to be closer to the main pipeline 10, thus obtaining more accurate pressure data. Although water pressure resistance may occur during the installation of the pressure gauge 30, the threaded connection makes screwing it in easier. During installation, some water may overflow from the threaded holes of the connecting plate 31; this can be easily resolved by wrapping PTFE tape around the rear section of the connecting part and wiping the surrounding area of ​​the pipeline dry after installation. Overall, this structure is relatively easy to install and operate.
