Description

Technical Field

[0001] This utility model relates to the field of water conservancy and water supply technology, and in particular to an explosion-proof water pipe for water conservancy and water supply. Background Technology

[0002] In the field of water supply, the safe operation of water pipes is crucial. The pipeline system that delivers and distributes water to users in water supply projects consists of pipes, fittings, and ancillary facilities. These ancillary facilities include regulating structures (water tanks, water towers, or water columns) and water supply pumping stations. Water supply pipelines are an indispensable water supply route. During the water supply process, due to various reasons such as pressure fluctuations and pipe aging, excessively high water pressure may occur inside the pipes. In practical applications, water pipes used in water supply typically require the following technologies:

[0003] 1. Possess sufficient strength and pressure resistance to withstand normal and sudden water pressure;

[0004] 2. Installation and maintenance should be convenient to reduce costs and improve efficiency.

[0005] Currently, various equipment and methods are used to achieve explosion-proof water pipes.

[0006] For example, a Chinese patent discloses an explosion-proof water supply network (publication number: CN220377418U). This network connects a protective pipe to the water supply pipe. When the water pressure inside the protective pipe becomes too high, a pressure relief mechanism automatically releases the pressure inside the protective pipe, thereby automatically releasing the pressure inside the water supply pipe. This prevents the water supply pipe and the protective pipe from bursting due to excessive water pressure, replacing the traditional method of explosion-proofing water pipes in water supply networks and avoiding the problem of water supply pipe bursts affecting residents' normal water use.

[0007] However, the above method has a prominent problem: the protective pipe in the device is a single structure. When upgrading the explosion-proof installation in an existing pipeline, the entire pipeline needs to be disassembled and replaced, which increases the difficulty and complexity of construction, and the water outage time will be longer, affecting residential or industrial water use and causing great inconvenience to users. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides an explosion-proof water pipe for water supply, which solves the technical problem that the protective pipe body in the device is an integral structure. When upgrading an existing pipeline for explosion-proof installation, the entire pipeline needs to be disassembled and replaced, which increases the difficulty and complexity of construction, results in longer water outages, affects residential or industrial water use, and causes great inconvenience to users.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] An explosion-proof water pipe for water supply includes an upper protective pipe. The outer surface of the upper protective pipe is provided with a quick-installation structure for split installation. The quick-installation structure includes a lower protective pipe and four inner rings. The lower protective pipe is located at the lower end of the upper protective pipe. The four inner rings are respectively snapped into the interior of the upper and lower protective pipes. The interior of the upper and lower protective pipes is provided with a snap-fit ​​mechanism for installing the inner rings. The snap-fit ​​mechanism includes two sets of slots, two sets of first springs, and two sets of arc-shaped locking blocks. The two sets of slots are respectively opened inside the four inner rings. The two sets of first springs are respectively sleeved inside the upper and lower protective pipes. The two sets of arc-shaped locking blocks are respectively sleeved at the ends of the two sets of first springs that are close to each other. The two sets of arc-shaped locking blocks are respectively slidably connected inside the upper and lower protective pipes.

[0011] Preferably, the two sets of arc-shaped locking blocks are respectively locked inside the two sets of locking slots, and the upper protective tube and the lower protective tube each have two mounting slots inside.

[0012] Preferably, two sealing strips are fitted inside the four mounting slots.

[0013] Preferably, the upper and lower protective tubes are fitted with four bolts inside, and each of the four bolts has a nut threaded onto its outer surface.

[0014] Preferably, all four nuts are located at the lower end of the lower protective tube, and a pressure relief plate is fixedly connected inside the upper protective tube.

[0015] Preferably, a second spring is sleeved at the lower end of the pressure relief plate, and a circular pressure relief baffle is sleeved at the lower end of the second spring.

[0016] Preferably, the annular pressure relief baffle is slidably connected inside the upper protective tube, and a pressure relief valve is fixedly connected to the upper end of the upper protective tube.

[0017] Preferably, the inner surfaces of the upper and lower protective pipes are fitted with two water supply pipe bodies, and the four inner rings are respectively set on the inner surfaces of the two water supply pipe bodies.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] First, cut slits matching the inner diameter of the upper and lower protective pipes in the existing fixed pipeline using cutting or sawing methods. Then, insert the four inner rings into the inner walls of the pipelines on both sides. When installing the lower protective pipe, slide it onto the outer surface of the inner ring from bottom to top. The outer surface of the inner ring will press against the arc-shaped locking block, causing it to slide away from the inner ring. When the inner ring and the inner wall of the lower protective pipe are in contact, the groove in the inner ring aligns with the arc-shaped locking block. At this point, the compressed first spring pushes the arc-shaped locking block to slide and engage in the groove, completing the engagement of the lower protective pipe and the inner ring. Next, align and fit the outer surfaces of the upper and lower protective pipes to complete the positioning and installation of the upper protective pipe and the other two inner rings. This allows for quick installation on existing fixed pipelines, facilitating upgrades and improvements to existing pipeline systems without requiring large-scale replacement of the original pipelines, saving resources and costs.

[0020] 2. When encountering high-pressure water flow, the water flow pushes the circular pressure relief baffle upwards, leaving a gap at the connection between the lower protective pipe and the circular pressure relief baffle. At this time, the high-pressure water flow flows along the pressure relief plate to the pressure relief valve and sprays upwards to relieve pressure, thereby protecting the water supply pipeline and preventing it from bursting due to excessive water pressure.

[0028] This application provides an explosion-proof water pipe for water supply, effectively solving the problem that the protective pipe body in the device is a single structure. When upgrading existing pipelines for explosion-proof installation, the entire pipeline needs to be disassembled and replaced, increasing the difficulty and complexity of construction, resulting in prolonged water outages, affecting residential or industrial water use, and causing great inconvenience to users. First, cuts matching the inner diameter of the upper and lower protective pipes are made in the existing fixed pipeline using cutting or sawing methods. Four inner rings are then inserted into the inner walls of the pipelines on both sides. When installing the lower protective pipe, it is inserted from bottom to top onto... The outer surface of the inner ring will press against the arc-shaped locking block, causing it to slide away from the inner ring. When the inner ring and the inner wall of the lower protective pipe are in contact, the groove in the inner ring aligns with the arc-shaped locking block. At this time, the compressed first spring pushes the arc-shaped locking block to slide and engage in the groove, completing the engagement of the lower protective pipe and the inner ring. Then, the outer surfaces of the upper and lower protective pipes are aligned and attached, thus completing the positioning and installation of the upper protective pipe and the other two inner rings. This allows for quick installation on existing fixed pipelines, facilitating upgrades and improvements to existing pipeline systems without the need for large-scale replacement of the original pipelines, saving resources and costs.

[0029] Example

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the technical solution in this application embodiment effectively solves the technical problem that when upgrading an existing pipeline for explosion-proof installation, the protective pipe body in the device is an integral structure, the entire pipeline needs to be disassembled and replaced, which increases the difficulty and complexity of construction, and the water outage time will be longer, affecting residential or industrial water use and causing great inconvenience to users. The overall idea is as follows: An explosion-proof water pipe for water supply includes an upper protective pipe 11. The outer surface of the upper protective pipe 11 is provided with a quick-installation structure for split installation. The quick-installation structure includes a lower protective pipe 12 and four inner rings 13. The lower protective pipe 12 is located at the lower end of the upper protective pipe 11. The four inner rings 13 are respectively snapped into the interior of the upper protective pipe 11 and the lower protective pipe 12. By connecting the upper protective pipe 11, The split design of the lower protective pipe 12 and the four inner rings 13 allows for easy installation of the entire device in existing fixed pipelines. This is achieved simply by cutting the existing pipelines to create incisions at the center inner diameter of the upper protective pipe 11 and lower protective pipe 12, resulting in higher installation efficiency. The upper and lower protective pipes 11 and 12 are equipped with a locking mechanism for installing the inner rings 13. This mechanism includes two sets of slots 14, two sets of first springs 15, and two sets of arc-shaped locking blocks 16. The two sets of slots 14 are respectively located inside the four inner rings 13. The two sets of first springs 15 are respectively fitted inside the upper and lower protective pipes 11 and 12. The two sets of arc-shaped locking blocks 16 are respectively fitted onto the adjacent ends of the two sets of first springs 15. The two sets of arc-shaped locking blocks 16 are slidably connected. Inside the upper protective tube 11 and the lower protective tube 12, two sets of arc-shaped locking blocks 16 are respectively locked into two sets of locking slots 14. During the installation operation, the four inner rings 13 are respectively fitted and inserted into the inner walls of the two side pipes. At this time, the lower protective tube 12 is first aligned with the outer surface of the inner ring 13 that matches its surface size. During the installation operation, the upper end is unobstructed and the installation position can be directly observed. When the lower protective tube 12 is fitted onto the outer surface of the inner ring 13 from bottom to top, the outer surface of the inner ring 13 will press and squeeze the arc-shaped locking blocks 16 to slide away from the inner ring 13. When the inner ring 13 and the inner wall of the lower protective tube 12 are in contact, the locking slots 14 opened in the inner ring 13 and the arc-shaped locking blocks 16 are aligned. At this time, the arc-shaped locking blocks 16 lose the squeezing force, and the first spring 1 is compressed. 5. Under the action of force, the arc-shaped locking block 16 is pushed to slide and engage in the slot 14, thus completing the engagement of the lower protective tube 12 and the inner ring 13. At this time, it is only necessary to align and fit the outer surfaces of the upper protective tube 11 and the lower protective tube 12 to complete the installation of the upper protective tube 11 and the other two inner rings 13. During installation, firstly, cut a slit in the existing fixed pipeline with a size matching the center inner diameter of the upper protective tube 11 and the lower protective tube 12 by cutting, sawing, or other methods. Then, fit the four inner rings 13 into the inner walls of the pipelines on both sides. When installing the lower protective tube 12, fit it onto the outer surface of the inner ring 13 from bottom to top. The outer surface of the inner ring 13 will press against the arc-shaped locking block 16, causing it to slide away from the inner ring 13. When the inner ring 13 and the inner wall of the lower protective tube 12 are in contact,The slot 14 inside the inner ring 13 aligns with the arc-shaped locking block 16. At this time, the compressed first spring 15 pushes the arc-shaped locking block 16 to slide and engage within the slot 14, completing the engagement of the lower protective tube 12 and the inner ring 13. Then, the outer surfaces of the upper protective tube 11 and the lower protective tube 12 are aligned and fitted together, thus completing the installation of the upper protective tube 11 and the other two inner rings 13.

[0031] Both the upper protective tube 11 and the lower protective tube 12 have two mounting grooves 17 inside. Two sealing strips 18 are fitted inside the four mounting grooves 17. During installation, the sealing strips 18 are inserted into the mounting grooves 17 to ensure a tight seal at the connection point. Four bolts 19 are fitted inside the upper and lower protective tubes 11 and 12. Nuts 21 are threaded onto the outer surface of each bolt 19, and all four nuts 21 are located at the lower end of the lower protective tube 12. Bolts 19 are inserted into the upper and lower protective tubes 11 and 12, and the upper and lower protective tubes 11 are connected by screwing the nuts 21 onto the outer surface of the bolts 19. During installation, the sealing strips 18 in the mounting grooves 17 ensure a tight seal at the connection point between the upper and lower protective tubes 11 and 12. Further connection and fixation are achieved by inserting bolts 19 into the upper and lower protective tubes 11 and screwing the nuts 21 onto the outer surface of the bolts 19.

[0032] A pressure relief plate 22 is fixedly connected inside the upper protective pipe 11. A second spring 23 is sleeved on the lower end of the pressure relief plate 22. A circular pressure relief baffle 24 is sleeved on the lower end of the second spring 23. The circular pressure relief baffle 24 is slidably connected inside the upper protective pipe 11. During water supply, water flows through the pipeline and through the upper protective pipe 11 and the lower protective pipe 12. When the high-pressure water flows through the lower end of the circular pressure relief baffle 24, the high-pressure water will push the circular pressure relief baffle 24 upward. When the sliding annular pressure relief baffle 24 and the inner wall of the lower protective pipe 12 are in contact, the water flow is blocked from spraying upwards. When the annular pressure relief baffle 24 is pushed upwards, a gap is left at the connection between the lower protective pipe 12 and the annular pressure relief baffle 24. At this time, the high-pressure water flows along the pressure relief plate 22 to the pressure relief valve 25 and sprays upwards to relieve pressure. The pressure relief valve 25 is fixedly connected to the upper end of the upper protective pipe 11. Two water supply pipe bodies 26 are sleeved on the inner surfaces of the upper protective pipe 11 and the lower protective pipe 12. Four inner rings 13 are respectively installed on the inner surface of the two water supply pipe bodies 26. The water supply pipeline is formed by the upper protective pipe 11, the lower protective pipe 12 and the four inner rings 13. The pressure is relieved during the water supply process by the pressure relief valve 25 and the circular pressure relief baffle 24. During the water supply process, the water flows through the water supply pipe body 26, the upper protective pipe 11 and the lower protective pipe 12. Under normal water pressure, the circular pressure relief baffle 24 is in the initial position under the action of the second spring 23. The circular pressure relief baffle 24 and the inner wall of the lower protective pipe 12 are in contact, blocking the water flow from spraying upward. When encountering high pressure water flow, the water flow pushes the circular pressure relief baffle 24 upward and slides upward. There is a gap at the connection between the lower protective pipe 12 and the circular pressure relief baffle 24. At this time, the high pressure water flows along the pressure relief plate 22 to the pressure relief valve 25 and sprays upward to relieve pressure, thereby protecting the water supply pipeline and preventing it from bursting due to excessive water pressure.

[0033] To address the problems existing in the prior art, this utility model provides an explosion-proof water pipe for water supply. First, by cutting or sawing, slits matching the inner diameter of the upper protective pipe 11 and lower protective pipe 12 are cut into the existing installed fixed pipeline. Four inner rings 13 are then respectively fitted and inserted into the inner walls of the two side pipelines. When installing the lower protective pipe 12, it is fitted onto the outer surface of the inner rings 13 from bottom to top. The outer surface of the inner rings 13 will adhere to and compress the arc-shaped locking block 16, causing it to slide away from the inner rings 13. When the inner rings 13 and the inner wall of the lower protective pipe 12 are in contact... When the slot 14 inside the inner ring 13 is aligned with the arc-shaped locking block 16, the compressed first spring 15 pushes the arc-shaped locking block 16 to slide and engage in the slot 14, completing the engagement of the lower protective tube 12 and the inner ring 13. Then, the outer surfaces of the upper protective tube 11 and the lower protective tube 12 are aligned and fitted together, thus completing the positioning and installation of the upper protective tube 11 and the other two inner rings 13. This allows for quick installation on existing fixed pipelines, facilitating upgrades and improvements to existing pipeline systems without requiring large-scale replacement of the original pipelines, saving resources and costs.

[0049] Working principle:

[0050] The first step involves installing the upper protective pipe 11 and the lower protective pipe 12, along with the four inner rings 13, inside the water supply pipe body 26 on both sides. During installation, the sealing strip 18 in the mounting groove 17 ensures the sealing of the gap between the upper protective pipe 11 and the lower protective pipe 12 after connection. Further connection and fixation are achieved by inserting bolts 19 into the upper protective pipe 11 and the lower protective pipe 12, and then tightening nuts 21 onto the outer surface of the bolts 19. During water supply, water flows through the water supply pipe body 26, the upper protective pipe 11, and the lower protective pipe 12. Inside, under normal water pressure, the annular pressure relief baffle 24 is in its initial position under the action of the second spring 23. The annular pressure relief baffle 24 and the inner wall of the lower protective pipe 12 are in contact, blocking the water flow from spraying upward. When encountering high-pressure water flow, the water flow pushes the annular pressure relief baffle 24 upward and slides upward. A gap is left at the connection between the lower protective pipe 12 and the annular pressure relief baffle 24. At this time, the high-pressure water flow flows along the pressure relief plate 22 to the pressure relief valve 25 and sprays upward to relieve pressure, thereby protecting the water supply pipeline and preventing it from bursting due to excessive water pressure.

[0051] The second step involves cutting slits in the existing fixed pipes to match the inner diameter of the upper protective pipe 11 and the lower protective pipe 12 using cutting or sawing methods. Four inner rings 13 are then inserted into the inner walls of the pipes on both sides. When installing the lower protective pipe 12, it is fitted onto the outer surface of the inner ring 13 from bottom to top. The outer surface of the inner ring 13 will press against the arc-shaped locking block 16, causing it to slide away from the inner ring 13. When the inner ring 13 and the inner wall of the lower protective pipe 12 are in contact, the slot 14 inside the inner ring 13 aligns with the arc-shaped locking block 16. At this point, the compressed first spring 15 pushes the arc-shaped locking block 16 to slide and engage in the slot 14, completing the engagement of the lower protective pipe 12 and the inner ring 13. Then, the outer surfaces of the upper protective pipe 11 and the lower protective pipe 12 are aligned and fitted together, thus completing the installation of the upper protective pipe 11 and the other two inner rings 13.

[0052] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
