[0017] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0018] Reference Figure 1 - Figure 5As shown, the utility model provides a technical solution: a corrosion-resistant water flow indicator, comprising a pipe 1, an extension pipe 2 is welded to the top of the pipe 1, the outer surface of one end of the extension pipe 2 is provided with a first thread line 3, the surface of the first thread line 3 is rotatably connected to a first internal thread sleeve 16, the interior of the first internal thread sleeve 16 is slidably connected to a visual glass plate 6, one end of the visual glass plate 6 is fixedly connected to a connecting rod 7, the surface of the connecting rod 7 is rotatably connected to a rotor 8, the interior of the extension pipe 2 is fixedly connected to a connecting plate 4, one end of the connecting plate 4 is provided with a circular hole 5, the bottom of the inner cavity of the extension pipe 2 is provided with a through groove 15, one end of the connecting rod 7 is in contact with the inside of the circular hole 5, and the staff passes the connecting rod 7 is inserted into the circular hole 5 provided inside the extension tube 2. When the first internal threaded sleeve 16 is twisted appropriately, it will tightly abut against one end of the visual glass plate 6. This tight joint is crucial because it ensures the stability and accuracy of the entire monitoring system. Once the connection and joint are completed, the staff can judge the flow rate by observing the rotation speed of the rotor 8 on the surface of the connecting rod 7. The rotation speed of the rotor 8 directly reflects the dynamics of the water flow in the pipeline 1, allowing the staff to monitor the status of the water flow in real time. This monitoring method not only improves work efficiency, but also enhances the understanding of the operating status of the pipeline 1 system, thereby ensuring the safe and stable operation of the entire system.

[0019] Reference Figure 5 As shown, in this embodiment: the material of the visual glass plate 6 is borosilicate glass. The material of the visual glass plate 6 is borosilicate glass. This material has excellent corrosion resistance and can effectively resist the erosion of various acidic and alkaline fluids, thereby ensuring the long-term stable operation of the water flow indicator in harsh environments. In addition, the high transparency of borosilicate glass allows staff to clearly observe the rotation of the rotor 8, thereby accurately judging the flow rate.

[0020] Reference Figure 3 As shown, in this embodiment: the outer surfaces of both sides of the pipe 1 are provided with second thread lines 9, the surfaces of the second thread lines 9 are rotatably connected with second internally threaded sleeves 10, and the interior of the second internally threaded sleeves 10 is slidably connected with a socket sleeve 11. By setting the second internally threaded sleeves 10 and the socket sleeves 11 as a double-union connection method, the staff can greatly simplify the operation process when performing maintenance or replacing the connecting pipe. Specifically, when the connecting pipe needs to be disassembled, the staff only needs to apply appropriate torque to the second internally threaded sleeve 10 to easily disassemble the entire connecting pipe from the system, which not only improves work efficiency, but also reduces the damage that may be caused to the equipment during the disassembly process, thereby ensuring the safety and convenience of operation.

[0021] Reference Figure 3As shown, in this embodiment: sealing grooves 12 are provided on both sides of the pipe 1 and one end of the extension pipe 2, and a sealing ring 13 is installed inside the sealing groove 12. The sealing ring 13 is made of high-temperature resistant and high-pressure resistant materials, ensuring that under extreme working conditions, such as high-temperature and high-pressure steam environments, it can still maintain good sealing performance and prevent fluid leakage. In addition, the shape of the sealing ring 13 is designed to be annular, which can be evenly distributed at the connection between the pipe 1 and the extension pipe 2, thereby achieving all-round sealing, further improving the reliability and safety of the water flow indicator.

[0022] Reference Figure 5 As shown, in this embodiment: the surface of the connecting rod 7 is fixedly connected to a limit plate 14, and there are two limit plates 14. The function of the limit plates 14 is to limit the position of the rotor 8 to prevent it from swinging left and right due to the influence of water flow, thereby ensuring the accuracy and stability of the rotor 8 when in use.

[0023] Reference Figure 3 As shown, in this embodiment: the pipe 1, the extension pipe 2, the connecting rod 7 and the rotor 8 are all made of a fully plastic structure and corrosion-resistant material. The pipe 1, the extension pipe 2, the connecting rod 7 and the rotor 8 are all made of a fully plastic structure and corrosion-resistant material. This design significantly improves the applicability of the water flow indicator in various corrosive fluid environments. Due to the corrosion resistance of the plastic material, the maintenance cost of the equipment is greatly reduced and the service life is extended. In addition, the all-plastic structure also has the advantages of light weight and easy installation and transportation, making the water flow indicator more flexible and convenient in various industrial applications.

[0024] Working principle: The staff inserts the connecting rod 7 into the circular hole 5 set inside the extension tube 2. When the first internal threaded sleeve 16 is twisted appropriately, it will tightly abut against one end of the visual glass plate 6. This tight joint is crucial because it ensures the stability and accuracy of the entire monitoring system. Once the connection and joint are completed, the staff can judge the flow rate by observing the rotation speed of the rotor 8 on the surface of the connecting rod 7. The rotation speed of the rotor 8 directly reflects the dynamics of the water flow in the pipeline 1, allowing the staff to monitor the status of the water flow in real time. This monitoring method not only improves work efficiency, but also enhances the control of the operation of the pipeline 1 system. The visibility of the flow indicator 6 is based on the understanding of the flow status, thereby ensuring the safety and stable operation of the entire system. The material of the visual glass plate 6 is borosilicate glass, which has excellent corrosion resistance and can effectively resist the erosion of various acidic and alkaline fluids, thereby ensuring the long-term stable operation of the water flow indicator in harsh environments. In addition, the high transparency of borosilicate glass allows the staff to clearly observe the rotation of the rotor 8, thereby accurately judging the flow rate. The second internal threaded sleeve 10 and the socket sleeve 11 are set to a double-union connection mode, which greatly simplifies the operation process when the staff performs maintenance or replaces the connecting pipe. Specifically, when the connecting pipe needs to be disassembled When the second internal threaded sleeve 10 is disconnected, the staff only needs to apply appropriate torque to the second internal threaded sleeve 10 to easily disassemble the entire connecting pipe from the system, which not only improves work efficiency, but also reduces damage to the equipment that may be caused during the disassembly process, ensuring the safety and convenience of operation. The sealing ring 13 is made of high-temperature and high-pressure resistant materials, ensuring that under extreme working conditions, such as high-temperature and high-pressure steam environments, it can still maintain good sealing performance to prevent fluid leakage. In addition, the shape of the sealing ring 13 is designed to be annular, which can be evenly distributed at the connection between the pipe 1 and the extension pipe 2, thereby achieving all-round sealing, further improving the water flow indicator. The reliability and safety of the water flow indicator are improved by the limit plate 14, which can limit the position of the rotor 8 to prevent it from swinging left and right under the influence of water flow, thereby ensuring the accuracy and stability of the rotor 8 when in use. The pipe 1, extension pipe 2, connecting rod 7 and rotor 8 are all made of full plastic structure and corrosion-resistant material. This design significantly improves the applicability of the water flow indicator in various corrosive fluid environments. Due to the corrosion resistance of the plastic material, the maintenance cost of the equipment is greatly reduced and the service life is extended. In addition, the full plastic structure also has the advantages of light weight, easy installation and transportation, making the water flow indicator more flexible and convenient in various industrial applications.
