Description

Technical Field

[0001] This utility model relates to the field of water supply equipment technology, specifically to a rural village pipeline water supply equipment. Background Technology

[0002] Rural village-level piped water supply systems are crucial infrastructure for ensuring safe drinking water for rural residents. Their operational efficiency and reliability directly impact residents' quality of life and drinking water safety. Water transmission primarily relies on pumps and pipeline systems, with the connections between pipes being a critical link in the entire water supply system. Currently, most water supply equipment connections utilize flanges and bolts, a traditional method that has revealed several significant shortcomings in practical use.

[0003] First, the pipe connection process is quite cumbersome. Installation requires aligning the flanges and tightening them one by one with multiple bolts, which is time-consuming and labor-intensive. Furthermore, during use, the pipe connections are subject to internal water pressure and external environmental factors such as ground subsidence, vibration, or impacts, which can easily cause them to wobble. This wobble causes the threaded parts at the pipe-flange connection to rotate relative to each other, leading to loosening of the connection.

[0004] Over long-term use, due to frequent stress and natural aging of materials, the sealing performance of pipe connections gradually declines, leading to frequent leaks. Leaks not only waste precious water resources but also cause insufficient pressure in the water supply network, failing to meet users' normal water needs. More seriously, leaks can cause secondary pollution within the water supply network, directly affecting the safety of drinking water and posing potential health risks to residents.

[0005] Therefore, in order to solve the above problems, overcome the shortcomings of existing technologies, improve the safety and durability of water supply equipment connections, and further ensure the drinking water safety of rural residents, there is an urgent need for an improved and optimized water supply pipeline connection device that can effectively improve the stability and leak-proof performance of pipeline connections. Utility Model Content

[0006] This utility model aims to provide a rural village-level water supply network device, which designs a connection device that is easy to install, stable in operation, and has good long-term sealing performance, effectively improving the stability and leak-proof performance of the pipeline connection, thereby solving the problem of water leakage at the connection of the water supply equipment.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A rural village water supply network includes a connector, a pipe, and a limiting mechanism. The connector has two end faces extending outwards along the axial direction to form an upper connecting plate and a lower connecting plate. Both end faces of the connector have axially arranged circular stepped holes, which are connected. Each stepped hole includes a first diameter section and a second diameter section with an inner diameter smaller than the first diameter section. The first diameter section has an internal thread, and the diameter of the second diameter section is equal to the inner diameter of the pipe. The end of the pipe has an external thread that mates with the internal thread of the connector. The limiting mechanism includes an upper limiting through hole, an upper limiting element, and a limiting groove. The upper limiting through hole is located on the upper connecting plate, and the inner wall end of the upper limiting through hole has an upper internal short thread. The limiting groove is axially opened on the outer periphery of the pipe. The middle part of the upper limiting element has an upper external short thread that mates with the upper internal short thread. The upper limiting element is detachably connected to the upper limiting through hole and the limiting groove.

[0009] The principle and advantages of this scheme are:

[0010] Existing water supply equipment often uses flange threaded connections, which are cumbersome and prone to loosening and leakage due to pipe vibration after prolonged use. This solution addresses the root cause of leakage by designing a new type of connector. The pipe is directly inserted into the connector and tightened using the external and internal threads. Then, an upper limit stop is inserted into the upper limit hole on the upper connecting plate. Rotating the upper limit stop ensures a tight fit between the upper external and internal short threads, preventing the upper limit stop from falling out of the hole. No wrenches or other tools are needed for tightening; the short threads only require two or three manual turns to secure them, making the process quick, convenient, and efficient. The lower end of the upper limit stop engages in the pipe's limiting groove, effectively preventing vibration and loosening during use. Furthermore, this design reduces the exposure of connecting components, minimizing the impact of the external environment on the pipe connection and ensuring the long-term stable operation of the water supply system, providing rural residents with safer and more reliable drinking water.

[0011] Preferably, as an improvement, the limiting mechanism further includes a lower limiting through hole and a lower limiting component. The lower limiting through hole is located at both ends of the lower connecting plate. The inner wall end of the lower limiting through hole is provided with a lower internal short thread, and the middle part of the lower limiting component is provided with a lower external short thread that mates with the lower internal short thread. The lower limiting component is detachably connected to the lower limiting through hole, and the lower end of the lower limiting component is engaged in the limiting groove. For areas with high water pressure and significant vibration, a lower limiting through hole and a lower limiting component can be added to enhance the overall limiting and fixing effect. The mating lower internal and lower external short threads prevent the lower limiting component from falling out, and the short threads only need to be manually tightened two or three turns to complete the fixing, without the need for tools, making it very quick and convenient.

[0012] Preferably, as an improvement, the upper and lower limit components are limit pins, each limit pin including a pin shaft and a limit pin piece, the limit pin piece being hinged to the end of the pin shaft, and the upper and lower external short threads being located in the middle of the pin shaft respectively.

[0013] The structure of the limiting component is further optimized by using a limiting pin. The upper end of the limiting pin is equipped with a rotatable limiting pin piece, which can realize quick installation and limiting. The upper and lower external short threads can quickly fix the pin shaft in the upper and lower limiting holes respectively. When the pin shaft is fixed, the upper and lower external short threads in the middle are in a tight fit with the upper and lower internal short threads.

[0014] Preferably, as an improvement, the end where the first diameter segment connects to the second diameter segment is provided with a step, and a sealing ring is provided on the step.

[0015] The sealing ring on the steps further enhances the sealing performance of the connection, ensuring a good seal during long-term use and effectively preventing leakage problems caused by insufficient sealing. At the same time, this design facilitates daily maintenance and replacement, providing double protection for the long-term stable operation of rural village water supply networks.

[0016] Preferably, as an improvement, the upper connecting plate and the lower connecting plate are provided with rectangular grooves coaxial with the upper limit through hole and the lower limit through hole, the depth of the groove is less than the thickness of the limit pin, and the length of the groove is greater than the length of the limit pin.

[0017] During use, the limit pin is located on the surface of the connector and may become loose due to accidental contact. Therefore, rectangular grooves coaxial with the upper and lower limit through holes are provided on the upper and lower connecting plates. After the limit pin is installed in place, rotate the limit pin to make it horizontal and lock it in the groove to prevent accidental contact and enhance the stability of the limit. The groove depth is less than the thickness of the limit pin, and the groove length is greater than the length of the limit pin. This ensures the implementation of the limit function and avoids disassembly difficulties caused by excessively deep grooves.

[0018] Preferably, as an improvement, the two ends of the limiting groove are annular, and a sealing ring is provided on the annular surface of the limiting groove near the external thread.

[0019] To further enhance the leak-proof and sealing effect at the connection, a sealing ring is installed on the annular surface of the limiting groove near the external thread. Once the pipe is installed, this sealing annular surface fits tightly against the bottom of the groove in the connector, effectively preventing moisture leakage along the thread gap. Furthermore, the annular surface design takes into account the effects of thermal expansion and contraction, allowing the sealing ring to maintain good elasticity under temperature changes, ensuring excellent sealing performance of the piping system under various environmental conditions. This not only reduces maintenance costs but also extends the service life of the equipment. Attached Figure Description

[0025] The following detailed description illustrates the specific implementation method:

[0026] The reference numerals in the accompanying drawings include: connector 1, pipe 2, limit pin 3, internal thread 101, upper limit through hole 102, lower limit through hole 103, sealing ring 104, groove 105, upper internal short thread 106, lower internal short thread 107, upper connecting plate 108, lower connecting plate 109, external thread 201, limit groove 202, sealing ring 203, pin 301, limit pin piece 302, upper external short thread 303, and lower external short thread 304.

[0027] The basic implementation examples are as follows: Figure 1-5 As shown:

[0028] As attached Figure 1 As shown, a rural village water supply network includes a connector 1, a pipe 2, and a limiting mechanism. The two end faces of the connector 1 extend axially outward to form an upper connecting plate 108 and a lower connecting plate 109. The space between the upper connecting plate 108 and the lower connecting plate 109 is unclosed, facilitating observation of the pipe 2's connection and enabling quick installation and fixing. Both end faces of the connector 1 have axially arranged circular stepped holes, which are interconnected. To ensure a tight fit between the pipe 2 and the connector 1, the stepped hole includes a first diameter section and a second diameter section with an inner diameter smaller than the first diameter section. The first diameter section has an internal thread 101, and the diameter of the second diameter section is equal to the inner diameter of the pipe 2. When the pipe 2 and the connector 1 are connected and fixed, the second diameter section and the pipe 2 form a smooth and continuous passage, facilitating water transmission. (See attached diagram) Figure 3 As shown, a step is provided at the end where the first diameter segment connects to the second diameter segment, and a sealing ring 104 is provided on the step. The sealing ring 104 can enhance the sealing performance of the connection, ensure that a good sealing state is maintained during long-term use, and effectively avoid water leakage problems caused by insufficient sealing.

[0029] As attached Figure 4 The end of the pipe 2 shown is provided with an external thread 201 that mates with the internal thread 101 of the connector 1; the limiting mechanism includes an upper limit through hole 102, an upper limit member, and a limiting groove 202. The upper limit through hole 102 is located on the upper connecting plate 108. The inner wall of the upper limit through hole 102 is provided with an upper internal short thread 106 that mates with the upper limit member to prevent the lower limit member from falling out. The upper external short thread 303 only needs to be manually tightened two or three turns to complete the fixation. No tools are required for operation, which is very quick and convenient. In order to further enhance the leak-proof and sealing effect of the connection, as shown in the attached... Figure 4 As shown, a limiting groove 202 is axially formed on the outer periphery of the pipe 2. The two ends of the limiting groove 202 are annular, and a sealing ring 203 is provided on the annular surface of the limiting groove 202 near the external thread 201. When the pipe 2 is installed in place, the annular surface of the sealing ring 203 fits tightly with the two end faces of the connector 1, effectively blocking the water leakage path.

[0030] For areas with high water pressure and significant vibration, a lower limit through hole 103 and a limit pin 3 are added. The lower limit through hole 103 is located at both ends of the lower connecting plate 109, and the inner wall end of the lower limit through hole 103 is provided with a lower internal short thread 107. (See attached...) Figure 5 As shown, the limiting pin 3 includes a pin shaft 301 and a limiting pin piece 302. The limiting pin piece 302 is hinged to the end of the pin shaft 301. The middle part of the limiting pin 3 is provided with an upper external short thread 303 and a lower external short thread 304 that mate with the upper internal short thread 106 and the lower internal short thread 107, respectively, to prevent the lower limiting component from falling out. The lower external short thread 304 can be fixed by manually tightening it two or three turns without the need for tools, which is very quick and convenient. The limiting pin 3 is detachably connected to the upper limiting through hole 102, the lower limiting through hole 103, and the limiting groove 202. The overall limiting and fixing effect is enhanced by adding the lower limiting through hole 103 and the lower limiting component.

[0031] To prevent accidental activation and enhance the limiting stability of the limiting pin 3, rectangular grooves 105, coaxial with the upper limiting through hole 102 and the lower limiting through hole 103, are provided on the upper connecting plate 108 and the lower connecting plate 109. The depth of the groove 105 is less than the thickness of the limiting pin piece 302, and the length of the groove 105 is greater than the length of the limiting pin piece 302. (See attached image) Figure 2 As shown, the limiting pin 302, after opening, is horizontally engaged within the groove 105. This ensures the limiting function while preventing disassembly difficulties caused by an excessively deep groove 105.

[0032] The specific implementation method is as follows:

[0033] As attached Figure 3 , 4As shown, first insert one end of pipe 2 with external thread 201 into one end of connector 1. Rotate pipe 2 or connector 1 to make external thread 201 and internal thread 101 fit tightly together, sealing ring 104 fits tightly against the end of pipe 2, and sealing ring 203 fits tightly against the end of connector. Then insert limit pin 3 into upper limit through hole 102 and lower limit through hole 103 respectively. Rotate to separate limit pin piece 302. Rotate 2-3 turns to insert pin shaft 301 into limit groove 202. Move limit pin piece 302 to a horizontal state and engage it in groove 105, as shown in the attached diagram. Figure 2 As shown, the installation of pipe 2 on one side is completed. The installation process for pipe 2 on the other side is the same as described above and will not be repeated here. After both ends of pipe 2 are installed in place, a pressure test is performed on the entire water supply equipment to verify its stability and sealing performance under actual working conditions. In this way, not only is the installation efficiency of the equipment improved, but the safety and reliability of the village's water supply network are also ensured.
