Description

Technical Field

[0001] This utility model relates to the field of water-saving technology for pipeline networks, specifically a water-saving device for water supply networks. Background Technology

[0002] Water supply networks, as a crucial part of urban infrastructure, are undeniably important. However, most water supply networks are buried deep in the soil, a unique environment that presents numerous challenges for their inspection. Moisture, salt, pH levels, and microorganisms in the soil can cause continuous corrosion to flanges, bolts, and gaskets. When flanges corrode, deform, or bolts break, excavation and replacement are necessary, resulting in high material costs as well as substantial labor and equipment rental expenses. Furthermore, flange connections located in the soil are difficult to detect due to environmental constraints. Delays in detection due to these challenges can lead to additional costs associated with post-repair system flushing and water quality testing. Using specialized testing equipment such as high-precision electronic leak detectors, correlators, and tracer gas detection equipment can result in high procurement costs. Pressure testing may require the temporary setup of testing facilities, increasing equipment rental and labor costs. For large-scale pipeline network testing, the long testing time can lead to a significant increase in labor costs, and if the testing is inaccurate, the increased costs from repeated testing and repairs are even more significant. Therefore, it is necessary to provide a water-saving device for water supply networks to solve the above problems. Utility Model Content

[0003] Based on the aforementioned problems in the existing technology, the purpose of this utility model is to provide a water-saving device for water supply networks to solve the problems mentioned in the background technology.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a water-saving device for a water supply network, including a first pipe with a first flange, a second pipe with a first flange, and a shell. The first pipe and the second pipe are connected by the first flange and the second flange. The first flange and the second flange are located inside the shell. A U-shaped pipe is connected to the bottom of the shell. A baffle with several guide holes is installed at the bottom end of the U-shaped pipe. The baffle divides the U-shaped pipe into an inlet section and an observation section. A float ball is provided in the observation section.

[0005] Furthermore, the end of the observation section is threaded with a transparent top cover.

[0006] Furthermore, the outer surface of the float is made of a reflective material.

[0007] Furthermore, the housing includes an upper protective cover and a lower protective cover. The upper protective cover has an annular upper receiving cavity with an opening facing downward and upper sealing portions on both sides that are consistent with the outer diameter of the first pipe and the second pipe. The diameter of the upper receiving cavity is larger than the outer diameter of the first flange and the second flange. The upper protective cover also has an upper connecting blind hole and an upper connecting through hole. The lower protective cover has a lower receiving cavity corresponding to the upper receiving cavity and opening upward, a lower sealing part corresponding to the upper sealing part, and the lower protective cover also has a lower connecting blind hole and a lower connecting through hole; The upper connecting blind hole is aligned with the lower connecting through hole, and the bolt passes through the lower connecting through hole and is threadedly connected to the upper connecting blind hole.

[0008] Furthermore, sealing strips are fixedly connected to the outer surfaces of the upper sealing part and the lower sealing part.

[0009] Furthermore, the bottom of the lower protective cover is connected to the water inlet section of the U-shaped pipe.

[0010] The beneficial effects of this utility model are as follows: This utility model provides a water-saving device for water supply networks. This device is equipped with a float and a transparent top cover. Only a small area of ​​soil on the top of the top cover needs to be dug out. By observing the float with a flashlight, it is possible to determine whether there is water leakage at the flange connection. The whole process is convenient and efficient, reducing the cost of purchasing detection devices and the amount of construction work. It can quickly detect water leakage, avoiding delays caused by difficult detection and avoiding additional costs such as system flushing and water quality testing after pipeline repair. By providing sealing strips on the surfaces of the upper and lower sealing parts, which abut against the pipe walls of the first and second pipes, a relatively sealed space is formed between the upper and lower receiving cavities. This prevents external rainwater and soil from entering the lower receiving cavity and flowing into the U-shaped pipe, avoiding accelerated aging of the flange due to contact with soil, and also avoiding misjudgment of the results, greatly increasing the accuracy of its detection.

[0013] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0014] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0015] like Figure 1-7 As shown, the present invention provides a technical solution: a water-saving device for a water supply network, comprising a first pipe 1 with a first flange 11, a second pipe 2 with a first flange 11, and a housing. The first pipe 1 and the second pipe 2 are connected by the first flange 11 and the second flange 21. The first flange 11 and the second flange 21 are located inside the housing. A U-shaped pipe 5 is connected to the bottom of the housing. A baffle 6 with several guide holes is installed at the bottom end of the U-shaped pipe 5. The baffle 6 divides the U-shaped pipe 5 into an inlet section 51 and an observation section 52. A float ball 7 is provided in the observation section 52.

[0016] The end of observation section 52 is threaded with a transparent top cover 8.

[0017] The outer surface of the float 7 is made of reflective material.

[0018] The cover includes an upper protective cover 3 and a lower protective cover 4. The upper protective cover 3 has an annular upper receiving cavity 33 with an opening facing downward and upper sealing parts 34 on both sides that are consistent with the outer diameter of the first pipe 1 and the second pipe 2. The diameter of the upper receiving cavity 33 is larger than the outer diameter of the first flange 11 and the second flange 21. The upper protective cover 3 also has an upper connecting blind hole 31 and an upper connecting through hole 32. The lower protective cover 4 has a lower receiving cavity 43 corresponding to the upper receiving cavity 33 and opening upward, a lower sealing part 44 corresponding to the upper sealing part 34, and the lower protective cover 4 also has a lower connecting blind hole 41 and a lower connecting through hole 42. The upper connecting blind hole 31 is aligned with the lower connecting through hole 42. The bolt passes through the lower connecting through hole 42 and is threaded to the upper connecting blind hole 31. The upper connecting through hole 32 is aligned with the lower connecting blind hole 41. The bolt passes through the upper connecting through hole 32 and is threaded to the lower connecting blind hole 41.

[0019] Sealing strips are fixedly connected to the outer surfaces of the upper sealing part 34 and the lower sealing part 44. This prevents water from seeping into the lower receiving cavity 43 and causing misjudgment of the results.

[0020] The bottom of the lower protective cover 4 is connected to the water inlet section 51 of the U-shaped pipe 5.

[0021] In one embodiment, how the device is used Specifically, the lower protective cover 4 is buried in advance at the construction site, the first flange 11 of the first pipe 1 is placed in the lower receiving cavity 43, at which time the outer peripheral wall of the first pipe 1 is in contact with the lower sealing part 44 on one side, and then the second flange 21 of the second pipe 2 is placed in the lower receiving cavity 43, at which time the outer peripheral wall of the second pipe 2 is in contact with the lower sealing part 44 on the other side, and then the first pipe 1 and the second pipe 2 are connected through the first flange 11 and the second flange 21. Align the upper connecting blind hole 31 with the lower connecting through hole 42, and thread the bolt through the lower connecting through hole 42 to the upper connecting blind hole 31. Align the upper connecting through hole 32 with the lower connecting blind hole 41, and thread the bolt through the upper connecting through hole 32 to the lower connecting blind hole 41. At this time, the upper protective cover 3 is fixed on the lower protective cover 4, and the first flange 11 and the second flange 21 are also located in the upper receiving cavity 33. At the same time, the upper sealing part 34 contacts the outer wall of the first pipe 1 and the second pipe 2. When water leaks at the connection between the first flange 11 and the second flange 21, the water falls into the inlet section 51 along the inner circumferential wall of the lower protective cover 4. As the water gradually increases, the liquid level also gradually rises. The water enters the observation section 52 through the baffle 6. At this time, the float 7 gradually rises in the observation section 52. By shining a flashlight through the top cover 8, the reflective float 7 can be observed. Therefore, it can be determined whether the pipeline is leaking. During routine inspections, staff only need to dig up the soil above the top cover 8. It should be noted that when there is no water accumulation inside the U-tube 5, the float 7 is not visible through the top cover 8 due to the bending effect of the U-tube 5, so there is no water leakage at the flange connection.

[0022] In summary, this device, equipped with a float 7 and a transparent top cover 8, only requires digging out a small area of ​​soil on top of the top cover 8 and observing the float 7 with a regular flashlight to determine whether there is water leakage at the flange connection. The whole process is convenient and efficient, reducing the cost of purchasing detection devices and the amount of construction work. It can quickly detect water leakage, avoiding delays caused by difficult detection and avoiding additional costs such as system flushing and water quality testing after pipeline repair. By providing sealing strips on the surfaces of the upper sealing part 34 and the lower sealing part 44, which abut against the pipe walls of the first pipe 1 and the second pipe 2, a relatively sealed space is formed between the upper receiving cavity 33 and the lower receiving cavity 43. This prevents external rainwater and soil from entering the lower receiving cavity 43 and flowing into the U-shaped pipe 5, avoids accelerated aging of the flange due to contact with soil, and avoids misjudgment of the results, greatly increasing the accuracy of its detection.

[0023] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
