Description

Technical Field

[0001] This utility model relates to the field of water pipelines, and in particular to a water pipeline node and a water pipeline system. Background Technology

[0002] Water pipelines are pipeline systems used to transport various types of water, such as domestic water, industrial water, rainwater, and sewage. In the industrial field, water pipelines provide factories and enterprises with the water needed for the production process, such as cooling water and boiler water. Steel pipes are often used as the main body of the pipelines because they have the characteristics of high strength, good toughness, and strong pressure resistance.

[0003] Industrial water is often hard, and long-term water transport will cause sediment to form inside the pipes, requiring regular inspection and cleaning. Currently, water pipe cleaning structures usually only have a simple filtration function to remove impurities and particles carried in the water flow. However, during long-term use of water pipes, a lot of impurities will accumulate and adhere to the inner wall of the pipes. This dirt is difficult to clean effectively. Long-term accumulation will not only reduce the inner diameter of the pipe, but also cause stress concentration in some parts of the pipe due to uneven dirt adhesion. In severe cases, it may cause pipe blockage or rupture. Summary of the Invention

[0004] This invention addresses the problem of difficulty in cleaning the dirt adhering to the pipe walls of water pipes by providing a water pipe node capable of cleaning the pipe walls.

[0005] To solve the above problems, the technical solution adopted by this utility model is a water pipe node, including a U-shaped pipe. The U-shaped pipe includes a first straight pipe, a second straight pipe, and a bend. The first and second straight pipes are vertically arranged with their openings facing upwards. The first straight pipe is connected to an inlet pipe, and the second straight pipe is connected to an outlet pipe. An ultrasonic descaling device is installed on the inlet pipe, and the probe of the ultrasonic descaling device extends into the interior of the inlet pipe. Inside the U-shaped pipe, a filter screen is installed at the connection between the first straight pipe and the bend. The filter screen is vertically arranged, and the lower end of the first straight pipe is open and equipped with a collection pipe located below the filter screen. This solution designs a water pipe node that connects to a water pipe. By installing an ultrasonic descaling device, dirt adhering to the pipe wall within a certain range is removed. The dispersed and pulverized dirt does not adhere to the pipe wall and is intercepted at the filter screen of the U-shaped pipe, falling into the collection pipe for easy centralized cleaning. This solution can prevent the pipe diameter from decreasing and stress concentration caused by dirt adhesion, avoiding blockage or rupture.

[0006] As a preferred implementation of a water pipeline node, a clamp is fitted onto the wall of the inlet pipe, a spring is located at the bottom of the clamp, and a mounting plate is located at the lower end of the spring. The ultrasonic descaling device is mounted on the bottom surface of the mounting plate. The clamp, spring, and mounting plate constitute an elastic mounting structure, which can buffer the impact of pipeline vibration on the ultrasonic descaling device, ensure its stable operation, and extend its service life.

[0007] As a preferred implementation of a water pipeline node, the lower end of the first straight pipe extends downward to form a sedimentation pipe, and the collection pipe is threadedly installed at the lower end of the sedimentation pipe. The upper interior of the collection pipe has a positioning step, on which a sealing gasket and a check valve are installed. The sealing gasket presses the check valve firmly against the positioning step. The sedimentation pipe facilitates impurity deposition, and the threaded connection of the collection pipe allows for easy disassembly and cleaning. The positioning step, sealing gasket, and check valve prevent backflow of impurities within the collection pipe while ensuring a tight seal at the connection point, preventing water leakage.

[0008] As a preferred implementation of a water pipeline node, the collection pipe is equipped with an observation window on its wall. The observation window allows operators to visually observe the deposition of impurities inside the collection pipe, promptly determine whether cleaning is necessary, and improve maintenance efficiency.

[0009] As a preferred implementation of a water pipe node, a second switching valve is provided on the first straight pipe or the inlet pipe; a backwashing mechanism is also provided on the bend pipe, with the backwashing mechanism facing the filter screen. The second switching valve can control the water flow, and together with the backwashing mechanism, it can wash away the dirt attached to the filter screen by water flow impact without disassembling the filter screen, reducing the amount of manual cleaning work and improving the convenience of use.

[0010] As a preferred implementation of a water pipe node, the backwashing mechanism includes a flushing pipe. A flushing pipe connector, connecting to the interior of the bend, is provided on the pipe wall of the bend. A mounting cap is located at the lower end of the flushing pipe connector. A fixing plate is provided on the outer periphery of the flushing pipe, clamped between the flushing pipe connector and the mounting cap. A nozzle is located at the upper end of the flushing pipe, facing the filter screen. The nozzle concentrates the water flow to impact the filter screen, enhancing the flushing effect. The cooperation of the fixing plate, flushing pipe connector, and mounting cap ensures a secure installation of the flushing pipe, guaranteeing a stable and reliable backwashing function.

[0011] As a preferred implementation of a water pipe joint, the fixing plate is provided with a positioning block, and the flushing pipe connector or the mounting cover is provided with a positioning groove, into which the positioning block is engaged. The cooperation between the positioning block and the positioning groove can accurately position the flushing pipe, ensuring that the nozzle is accurately oriented towards the filter screen, while preventing the flushing pipe from rotating during installation and ensuring the backwashing effect.

[0012] As a preferred implementation of a water pipeline node, a bridging filter pipe is also provided between the inlet pipe and the outlet pipe. The interface between the inlet pipe and the bridging filter pipe is located above the second switching valve, and a first switching valve is provided on the bridging filter pipe. When it is necessary to clean the collection pipe or filter screen, the second switching valve is closed and the first switching valve is opened. Water can flow directly from the inlet pipe to the outlet pipe through the bridging filter pipe, ensuring continuous system operation, avoiding downtime due to maintenance, and improving system efficiency.

[0013] As a preferred implementation of a water pipeline node, a one-way valve is provided on the outlet pipe or the second straight pipe, and the one-way valve is open in the direction of the outlet pipe.

[0014] Furthermore, this utility model also provides a water system including the aforementioned water pipe nodes. This water system integrates these pipe nodes, effectively preventing pipe scaling and blockage, facilitating impurity cleaning and system maintenance, ensuring long-term stable and efficient operation of the water system, and reducing the failure rate and maintenance costs.

[0015] As can be seen from the above technical solutions, the advantages of this utility model are as follows: This solution installs an ultrasonic descaling device in the water inlet pipe, utilizing its cavitation and chemical effects to disperse and loosen the scale. Combined with a U-shaped internal filter screen, impurities are intercepted and fall into the collection pipe, preventing pipe diameter reduction, stress concentration, and blockage / rupture due to scale adhesion. The elastic structure composed of clamps, springs, and mounting plates buffers vibration, ensuring stable operation of the ultrasonic descaling device. The deposition pipe and threaded collection pipe facilitate impurity deposition and disassembly for cleaning. Positioning steps, sealing gaskets, and anti-reverse plates prevent impurity backflow and water leakage. The observation window in the collection pipe allows for intuitive judgment of cleaning timing, improving maintenance efficiency. The second switching valve, in conjunction with the backwashing mechanism's nozzle, can flush the filter screen, reducing manual disassembly and cleaning workload. Positioning blocks and positioning grooves ensure accurate installation of the flushing pipe. The bridging filter pipe and the first switching valve maintain system water flow during maintenance, avoiding downtime. The one-way valve prevents backflow, ensuring system safety. The integrated water system can operate stably and efficiently for a long time, reducing failure and maintenance costs. Attached Figure Description

[0023] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0024] Example 1

[0025] A water pipe joint includes a U-shaped pipe 3, which includes a first straight pipe 3-1, a second straight pipe 3-2, and a bend 3-3. The first straight pipe 3-1 and the second straight pipe 3-2 are vertically arranged with their openings facing upwards. The first straight pipe 3-1 is connected to an inlet pipe 1, and the second straight pipe 3-2 is connected to an outlet pipe 2. An ultrasonic descaling device 11 is installed on the inlet pipe 1, and the probe of the ultrasonic descaling device 11 extends into the interior of the inlet pipe 1. Specifically, a clamp 22 is fitted on the wall of the inlet pipe 1, and a spring 23 is provided at the bottom of the clamp 22. A mounting plate 24 is provided at the lower end of the spring 23, and the ultrasonic descaling device 11 is installed on the bottom surface of the mounting plate 24.

[0026] The lower end of the first straight pipe 3-1 extends downward to form a deposition pipe 8. The lower end of the deposition pipe 8 is provided with an external thread, through which a collection pipe 9 is installed, such as... Figure 3As shown, the upper inner wall of the collecting pipe 9 is machined with internal threads for engagement with external threads. The diameter of the portion containing the internal threads is larger than the lower diameter of the collecting pipe 9, thus forming a positioning step 9-1 at the upper end of the collecting pipe 9. A sealing gasket 13 and a check valve 12 are installed on the positioning step. After the internal and external threads are tightened, the lower end of the sedimentation pipe 8 presses against the sealing gasket 13 to achieve a seal. Simultaneously, the sealing gasket 13 presses the check valve 12 against the positioning step 9-1. Inside the U-shaped pipe 3, a filter screen 25 is provided at the connection between the first straight pipe 3-1 and the bent pipe 3-3. The filter screen 25 is vertically arranged, with its lower end connected to the upper end of the sedimentation pipe 8, thus placing the collecting pipe 9 below the filter screen 25.

[0027] This node is installed at any position on the water pipeline. Its working principle is as follows: water flows through the inlet pipe 1 and the second switch valve 6 and passes through the filter screen 25. Impurities in the water flow will be blocked by the filter screen 25 and then enter the interior of the collection pipe 9 under the action of gravity and water flow, where they will be deposited. The filtered water will then flow through the U-shaped pipe 3 and the outlet pipe 2 to the external equipment. After the device has been working for a certain period of time, the operator can turn on the ultrasonic descaling device 11. The ultrasonic descaling device 11 will crush and loosen the impurities attached to the wall of the inlet pipe 1 and then flow through the second switch valve 6 and pass through the filter screen 25, where they will be deposited inside the collection pipe 9. The wall of the collection pipe 9 is also provided with an observation window 14, through which the amount of impurities in the collection pipe 9 can be seen. After a certain amount of impurities are collected, the collection pipe 9 can be unscrewed for cleaning.

[0028] To achieve non-stop cleaning of the entire water pipeline, a second switching valve 6 is installed on the first straight pipe 3-1 or the inlet pipe 1, and a one-way valve 7 is installed on the outlet pipe 2 or the second straight pipe 3-2. The one-way valve 7 opens towards the outlet pipe 2. Simultaneously, a backwashing mechanism is installed on the bend pipe 3-3, facing the filter screen 25. Figure 4 As shown, the backwashing mechanism includes a flushing pipe 18. A flushing pipe connector 10, connecting to the interior of the bend 3-3, is provided on the pipe wall of the bend. A mounting cap 16 is provided at the lower end of the flushing pipe connector 10. A fixing plate 17 is provided on the outer periphery of the flushing pipe 18, and the fixing plate 17 is clamped between the flushing pipe connector 10 and the mounting cap 16. A nozzle 19 is provided at the upper end of the flushing pipe 18, facing the filter screen 25. A positioning block 20 is provided on the fixing plate 17, and a positioning groove 21 is provided on the flushing pipe connector 10 or the mounting cap 16, into which the positioning block 20 is engaged. A bridging filter pipe 4 is also provided between the inlet pipe 1 and the outlet pipe 2. The interface between the inlet pipe 1 and the bridging filter pipe is located above the second switching valve 6. A first switching valve 5 is provided on the bridging filter pipe 4.

[0029] Therefore, the operator can close the second switch valve 6 and open the first switch valve 5. At this time, the water flowing in through the inlet pipe 1 will directly pass through the bridging filter pipe 4 and enter the interior of the outlet pipe 2. Then the operator can remove the collection pipe 9 and manually clean it. At the same time, the operator can also open the external water pipe, and the water in the pipe will be sprayed out through the flushing pipe 18 and the nozzle 19, directly impacting one side of the filter screen 25, so that a small part of the impurities attached to the filter screen 25 will be washed off and flow out with the water flow through the sedimentation pipe 8.

[0030] Example 2

[0031] This embodiment further provides a water system, including the water pipe nodes provided in Embodiment 1. In the water system, a set of the aforementioned water pipe nodes can be set at certain intervals, so that each ultrasonic descaling device can cover the entire water system.

[0032] As can be seen from the above embodiments, the beneficial effects of this utility model are as follows: This solution installs an ultrasonic descaling device in the water inlet pipe, utilizing its "cavitation" and "chemical" effects to disperse and loosen the dirt. Combined with a U-shaped internal filter screen, impurities are intercepted and fall into the collection pipe, preventing the pipe from shrinking in diameter, stress concentration, and clogging due to dirt adhesion. The elastic structure composed of clamps, springs, and mounting plates can buffer vibrations, ensuring stable operation of the ultrasonic descaling device. The sedimentation pipe and the threaded collection pipe facilitate impurity deposition and disassembly for cleaning. Positioning steps, sealing gaskets, and anti-reverse plates prevent impurity backflow and water leakage. The observation window in the collection pipe allows for intuitive judgment of cleaning timing, improving maintenance efficiency. The second switching valve, in conjunction with the nozzle of the backwashing mechanism, can flush the filter screen, reducing manual disassembly and cleaning workload. Positioning blocks and positioning grooves ensure accurate installation of the flushing pipe. The bridging filter pipe and the first switching valve maintain system water flow during maintenance, avoiding downtime. The one-way valve prevents backflow, ensuring system safety. The water system integrating this node can operate stably and efficiently for a long time, reducing failure and maintenance costs.

[0033] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
