Description
Technical Field
[0001] This utility model relates to the technical field of corrosion rate testing devices, and specifically to a water treatment corrosion rate testing device. Background Technology
[0002] In water treatment systems, corrosion monitoring of water quality is necessary. Excessive water corrosivity can severely impact the lifespan of pipes and facilities, and corrosion products can also pollute the water. Furthermore, the leaching of metal ions from the pipes can pose a threat to human health. To monitor water corrosivity, existing technologies involve immersing a metal plate in water for a period of time, then removing the plate and measuring the weight change. Higher water corrosivity results in a larger weight change, while lower corrosivity results in a smaller weight change, thus achieving water corrosivity monitoring.
[0003] Chinese utility model patent CN206740613U discloses a dynamic average corrosion rate measuring device, which is installed on the inlet pipeline of a water treatment system. The device includes a bypass pipeline, which is equipped with a suspension device for suspending test pieces. The test pieces are placed inside the bypass pipeline. The device has a small footprint, is easy to install on-site, and places the test pieces in the actual operating environment of the system fluid, reflecting the corrosion state of the test pieces. The test pieces are easy to install and remove, do not affect the normal operation of the water treatment system, and the device is reusable.
[0004] In the aforementioned dynamic average corrosion rate measuring device, a hanging chain is used to connect the hanging plates. When water flows in the pipeline, it pushes the hanging plates to swing. When the hanging plates are corroded, due to the structural strength of the hanging plates, the hanging plates and the hanging chain collide with the inner wall of the pipeline during the swinging process, causing the hanging plates to easily break and fall off. Therefore, there is a technical problem of poor stability of the hanging plates. Utility Model Content
[0005] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a water treatment corrosion rate testing device, which includes an inlet pipe, a monitoring pipe, a return pipe, a water valve and a monitoring component. This water treatment corrosion rate testing device has the advantage of good stability of the plate.
[0006] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is as follows:
[0007] A water treatment corrosion rate testing device includes an inlet pipe, a monitoring pipe, a return pipe, a water valve, and a monitoring component. The two ends of the water valve are respectively connected to the inlet pipe and the monitoring pipe. The return pipe is connected to the monitoring pipe. The monitoring component is installed on the monitoring pipe and includes a cover plate, an end cap, a connecting plate, and a monitoring unit. The cover plate is fixedly installed on the monitoring pipe and has a through groove. The end cap is detachably installed on the cover plate and blocks the through groove. The connecting plate is fixedly connected to the end cap and is installed on the end cap and extends into the monitoring pipe. The monitoring unit includes a stud and is installed on the connecting plate. The stud is equipped with a hanging plate.
[0008] This improves the stability of the hanging plates, prevents material from falling off due to collisions, and prevents the monitoring accuracy of water corrosion from being affected by the impact of water flow on the hanging plate material falling off.
[0009] Preferably, the stud is threadedly connected to the connecting plate.

[0013] Preferably, the stud passes through the connecting plate, the length of the stud is greater than the thickness of the connecting plate, and hanging plates are installed at both ends of the stud.
[0014] This setup ensures that the mounting plates fixed at both ends of the stud maintain a certain distance from the connecting plate, allowing both sides of the mounting plates to be corroded by water, thus improving the monitoring sensitivity of the mounting plates.
[0015] Preferably, at least two monitoring units are provided.
[0016] This setup, which uses two monitoring units to monitor simultaneously, improves the accuracy of the monitoring.
[0017] Preferably, the monitoring unit is located between the water valve and the return water pipe.

[0020] This design improves the seal between the end cap and the cover plate.
[0021] Preferably, the end cap near the cover plate is provided with a second sealing ring that engages with the retaining ring.
[0022] This design further enhances the sealing performance.
[0023] Preferably, the thickness of the second sealing ring is greater than the thickness of the first sealing ring, the outer side of the retaining ring is fixedly connected to the cover plate, and the first sealing ring is located on the side of the second sealing ring near the through groove.
[0024] By setting the first sealing ring to the side of the second sealing ring near the through groove, the second sealing ring is positioned close to the connection between the retaining ring and the cover plate, allowing the retaining ring to support the second sealing ring more stably and preventing the second sealing ring from damaging the retaining ring.
[0025] Preferably, the monitoring tube is located above the water valve and the inlet pipe, and the cover plate is located at the upper end of the monitoring tube.

[0035] To make the objectives, technical solutions and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments. However, the scope of protection of this utility model is not limited to the specific embodiments described below.
[0036] refer to Figure 1-3 A water treatment corrosion rate testing device includes an inlet pipe 11, a monitoring pipe 12, a return pipe 13, a water valve 14, and a monitoring component. The two ends of the water valve 14 are connected to the inlet pipe 11 and the monitoring pipe 12, respectively. The return pipe 13 is connected to the monitoring pipe 12, and the monitoring component is installed on the monitoring pipe 12.
[0037] The monitoring assembly includes a cover plate 21, a head 22, a connecting plate 23, and a monitoring unit. The cover plate 21 is fixedly installed on the monitoring tube 12 and has a through groove 24. The head 22 is detachably installed on the cover plate 21 and blocks the through groove 24. The connecting plate 23 is fixedly connected to the head 22, and the connecting plate 23 is installed on the head 22 and extends into the monitoring tube 12. The connecting plate 23 extends along the length of the monitoring tube 12.
[0038] The monitoring unit includes a stud 31, which is mounted on a connecting plate 23 and has a mounting plate 32. The inlet pipe 11, monitoring pipe 12, and return pipe 13 are all stainless steel. The connecting plate 23, stud 31, and screws 34 are all made of PVC, providing good corrosion resistance. The stud 31 is threaded into the connecting plate 23, facilitating its installation. The stud 31 has a threaded hole 33 at its end, through which a screw 34 threaded into the hole passes. The stud 31 also has an internal hexagonal hole 35 communicating with the threaded hole 33, the width of which is smaller than the width of the threaded hole 33. The stud 31 passes through the connecting plate 23, its length exceeding the thickness of the connecting plate 23, and mounting plates 32 are installed at both ends. Two monitoring units are configured. Simultaneous monitoring by these two units improves monitoring accuracy. The monitoring unit is located between the water valve 14 and the return water pipe 13. It ensures that the water flowing from the water valve 14 to the return water pipe 13 can pass through the monitoring unit, so that the water can flow continuously through the monitoring unit, thereby ensuring the accuracy of the monitoring unit in monitoring the water corrosion rate.
[0039] The end cap 22 is threadedly connected to the cover plate 21. A first sealing ring 15 is provided at the end of the end cap 22 near the cover plate 21. A retaining ring 17 is fixedly connected to the cover plate 21, surrounding the through groove 24. The first sealing ring 15 engages with the retaining ring 17. A second sealing ring 16 is provided at the end of the end cap 22 near the cover plate 21, engaging with the retaining ring 17. The thickness of the second sealing ring 16 is greater than the thickness of the first sealing ring 15. The outer side of the retaining ring 17 is fixedly connected to the cover plate 21. The first sealing ring 15 is located on the side of the second sealing ring 16 near the through groove 24. The monitoring pipe 12 is located above the water valve 14 and the inlet pipe 11, and the cover plate 21 is located at the upper end of the monitoring pipe 12.
[0040] This embodiment has the following advantages:
[0041] Connect the inlet pipe 11 and return pipe 13 to the water treatment system, allowing water in the system to flow sequentially through the purified water pipe, water valve 14, monitoring pipe 12, and return pipe 13. After the device is installed and the water treatment system is operating normally, open water valve 14 to allow water to flow from inlet pipe 11 to monitoring pipe 12. Once the monitoring pipe 12, which contains the hanging plate 32, is full, the water flows back to the water treatment system through return pipe 13. After a period of time, remove the connecting plate 23 and hanging plate 32 from the monitoring pipe 12. Rotate screw 34 to remove hanging plate 32 from stud 31 and weigh it. By comparing the weight change before and after immersion in water, the corrosiveness of the water can be determined. A large weight change in hanging plate 32 indicates high water corrosiveness, while a small weight change indicates low water corrosiveness, thus achieving the function of monitoring the corrosiveness of hanging plate 32.
[0042] The cover plate 21 provides support to the connecting plate 23 and the hanging plate 32 through the end cap 22, so that the hanging plate 32 can remain stable in the water flow, effectively avoiding the collision between the hanging plate 32 and the inner wall of the pipe, improving the stability of the hanging plate 32, preventing the material of the hanging plate 32 from falling off due to collision, and preventing the monitoring accuracy of water corrosion from being affected by the impact of the water flow on the material of the hanging plate 32 falling off.
[0043] This water treatment corrosion rate testing device features a compact structure and ingenious design, enabling it to adapt to water systems of varying sizes and types, ensuring stable and reliable operation under diverse conditions. Furthermore, the instrument is easy to install and maintain, significantly reducing usage difficulty and cost while improving work efficiency.
[0044] A threaded hole 33 is provided at the end of the stud 31 to facilitate the rotation of the screw 34 at the end of the stud 31. The screw 34 can press the hanging piece 32 onto the end of the stud 31, thereby fixing the hanging piece 32 to the end of the stud 31. The width of the internal hexagonal hole 35 is smaller than the width of the threaded hole 33, allowing an internal hexagonal wrench that mates with the internal hexagonal hole 35 to pass through the threaded hole 33 and be inserted into the internal hexagonal hole 35. This allows the stud 31 to be rotated using the internal hexagonal wrench, thus facilitating the rotation of the stud 31.
[0045] The length of the stud 31 is greater than the thickness of the connecting plate 23, so that both ends of the stud 31 can extend out of both sides of the connecting plate 23. This allows the hanging plates 32 fixed at both ends of the stud 31 to maintain a certain distance from the connecting plate 23, thereby allowing water to flow to the side of the hanging plate 32 closest to the connecting plate 23. Both sides of the hanging plate 32 can be corroded by water, improving the monitoring sensitivity of the hanging plate 32.
[0046] Hanging plates 32 are installed at both ends of the stud 31. Monitoring is carried out simultaneously through the two hanging plates 32, which improves the accuracy of monitoring.
[0047] By fitting the first sealing ring 15 with the retaining ring 17, the first sealing ring 15 blocks the gap between the end cap 22 and the retaining ring 17, thereby improving the sealing performance between the end cap 22 and the cover plate 21.
[0048] By simultaneously sealing the gap between the end cap 22 and the retaining ring 17 with the first sealing ring 15 and the second sealing ring 16, the sealing performance is further improved.
[0049] The thickness of the second sealing ring 16 is greater than that of the first sealing ring 15, resulting in a better sealing effect. Furthermore, the pressure exerted on the retaining ring 17 by the end cap 22 when the second sealing ring 16 is pressed against it is greater than the pressure exerted on the retaining ring 17 when the end cap 22 is pressed against it. Therefore, by positioning the first sealing ring 15 on the side of the second sealing ring 16 near the through groove 24, and placing the second sealing ring 16 close to the connection between the retaining ring 17 and the cover plate 21, the retaining ring 17 can more stably support the second sealing ring 16, preventing the second sealing ring 16 from damaging the retaining ring 17.
[0050] Positioning the cover plate 21 above the monitoring pipe 12, water valve 14, and water inlet pipe 11 reduces the water pressure at the cover plate 21 and end cap 22, thereby decreasing the risk of leakage at the end cap 22.
[0051] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the utility model.
