Description

Technical Field

[0001] This utility model relates to the field of measuring device technology, specifically a tubular flow pH probe measuring device. Background Technology

[0002] The pipe-flow pH probe is a device used for real-time monitoring of the acidity and alkalinity of fluids within pipelines. Through a specially designed flow structure, it allows the liquid being measured to continuously flow through the sensor section. It incorporates a high-precision glass electrode and a reference electrode, converting H⁺ concentration into an electrical signal for online dynamic detection. It is widely used in chemical and other fields.

[0003] Existing pH probes are directly installed inside the pipeline. Each time the sampling pump takes a sample, changes in the flow rate and pressure of the fluid within the pipeline, as well as the presence of air, can impact and interfere with the pH probe, causing significant data deviations. Pressure fluctuations may also cause dissolved gases in the fluid to precipitate, generating bubbles. These bubbles adhering to the pH probe surface interfere with measurements, leading to abnormal readings. Furthermore, bubbles impede direct contact between the probe and the fluid, affecting ion transfer and exchange, and potentially damaging the pH probe. Therefore, optimization and improvement are necessary. Utility Model Content

[0016] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0018] like Figure 1 - Figure 4 As shown, this application provides a tubular flow pH probe measuring device, including: a measuring cup 1, a cup lid 4 connected to the top of the measuring cup 1, and a detection probe 6 connected to the inner side of the cup lid 4; a measuring adjustment assembly including a water inlet connector 2 and an automatic air vent valve 5, the water inlet connector 2 being fixedly connected to the outer side of the measuring cup 1, the automatic air vent valve 5 being installed on the top of the cup lid 4 with its air vent penetrating through the cup lid 4, and the measuring adjustment assembly being used for adjustment during measurement by the detection probe 6; specifically, as... Figure 1 As shown, a water outlet connector 3 is fixedly connected to one end of the outer side of the measuring cup 1. The installation position of the water outlet connector 3 is lower than that of the water inlet connector 2. The solution enters from the water inlet connector 2 and then flows out from the water outlet connector 3, so that the solution enters the measuring cup 1 and flows out after being buffered, which plays a certain role in flow rate control and reduces the impact force of the solution on the detection probe 6.

[0019] Specifically, such as Figure 3 As shown, the inner side of the cup lid 4 is provided with a probe mounting port 8 that is slidably connected to the detection probe 6. The detection probe 6 slides inside the probe mounting port 8, and its height can be controlled as needed.

[0020] Specifically, such as Figure 3As shown, a limiting ring 10 is connected to the bottom outer side of the detection probe 6, and a positioning ring 11 is connected to the top of the limiting ring 10. The limiting ring 10 is located at the bottom inner side of the detection probe 6. During installation, it fits against the bottom wall of the cup lid 4 for limiting. Then, the positioning ring 11 is used to connect and position the probe at the top. Both the limiting ring 10 and the positioning ring 11 are fitted on the outside of the detection probe 6. The elastic compression brought by the rubber limiting ring 10 and the positioning ring 11 positions the detection probe 6. The different positions of the limiting ring 10 and the positioning ring 11 are used to control the height of the detection probe 6 inserted into the measuring cup body 1. The limiting ring 10 and the positioning ring 11 are located at the upper and lower ends of the cup lid 4, respectively, and are in the same vertical position as the probe mounting port 8.

[0021] Specifically, such as Figure 3 As shown, a data cable connector 7 is fixedly connected to the top of the detection probe 6. The data cable connector 7 transmits the data measured by the detection probe 6 for pH detection to the display terminal.

[0022] The sealing connection assembly includes a face cover tube clamp 13, which is located at the top of the cup lid 4. A face cover tube clamp 2 15 is rotatably connected to one side of the face cover tube clamp 13. An adhesive ring 17 is connected to the inner side of the face cover tube clamp 2 15. The sealing connection assembly is used for the sealing connection of the measuring device.

[0023] Specifically, such as Figure 3 As shown, a pressing washer 9 is fixedly connected to the inner side of the bottom end of the cup lid 4. The pressing washer 9 fits against the top of the inner wall of the measuring cup body 1. The pressing washer 9 is used to improve the sealing of the connection between the cup lid 4 and the measuring cup body 1.

[0024] Specifically, such as Figure 4 As shown, a rotating connector 12 is fixedly connected to the inner side of the face cap tube clamp 13, and a face cap tube clamp 2 15 is connected to one side of the rotating connector 12. The face cap tube clamp 13 and the face cap tube clamp 2 15 can be closed to form a ring for clamping and fixing the cup lid 4.

[0025] Specifically, such as Figure 4As shown, a semi-circular component 16 is fixedly connected to the outer side of the face cover tube clip 15. The semi-circular component 16 is used to guide the sliding ring of the slider 18. The slider 18 is slidably connected to the outer side of the semi-circular component 16. One end of the slider 18 is fixedly connected to a connector 19. The slider 18 and connector 19 slide on the semi-circular component 16 on the outer side of the face cover tube clip 15 for position adjustment. The connector 19 is provided with two protrusions. The inner side of the face cover tube clip 13 is provided with a plug hole 14 that matches the connector 19. An elastic positioning pin 20 is slidably connected to the inner side of the plug hole 14. The opening size of the plug hole 14 is larger than the size of the connector 19 to accommodate the position difference when the connector 19 moves in a ring. The elastic positioning pin 20 consists of a positioning rod and a spring. Pressing the outer side of the elastic positioning pin 20 makes the protruding part that restricts the sliding of the connector 19 hidden inside the plug hole 14, which facilitates the restriction and sliding out of the connector 19.

[0026] In this embodiment, the tubular flow measuring device assembled by measuring cup 1, inlet connector 2, and outlet connector 3 allows the solution to flow stably within the measuring cup 1, effectively slowing down the flow rate. Internal gas can also be automatically discharged through the automatic exhaust valve 5, ensuring that the pH measuring probe 6 makes full and uniform contact with the solution, thereby improving the accuracy and repeatability of the measurement. When connecting the measuring cup 1 and the cup lid 4, a pressing washer 9 and a fitting rubber ring 17 are used for sealing the inner and outer sides. Clip-on faceplate clips 13 and 15 are used for fixation. The sliding adjustment connector 19 works in conjunction with the elastic positioning pin 20, providing convenient installation and disassembly and facilitating device maintenance.

[0027] Specifically, when testing the pH value of a solution, the solution enters the measuring cup 1 through the inlet connector 2. The height difference between the inlet connector 2 and the outlet connector 3 allows the solution to flow upwards and downwards, thus controlling the flow rate. The probe 6 is positioned close to the inlet connector 2, allowing the solution to flow evenly and stably through the probe 6. When gas is generated inside the measuring cup 1, it is automatically discharged through the automatic exhaust valve 5, thereby extending the probe's lifespan. The design of the measuring cup 1 also reduces the impact force of the solution on the probe 6. During the installation of the probe 6, the limiting ring 10 is located at the bottom of the inner side of the probe 6. During installation, the cup lid 4 is fitted to the bottom wall for positioning, and then the positioning ring 11 is used to connect and position it at the top for easy height adjustment. After long-term use, the detection probe 6 needs to be removed for maintenance. Press the elastic positioning pin 20 to squeeze the spring inward, and the protruding part will be hidden. At this time, the locking slider 18 slides on the outside of the semi-circular part 16, allowing the plug 19 to move out of the plug hole 14. Unfold the face cover tube clip 2 15 and face cover tube clip 1 13 to release the restriction on the cup lid 4. Then remove the cup lid 4 to clean and maintain the inside of the measuring cup body 1, thus improving the service life of the measuring device.
