[0039] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0040] like Figures 1 to 4 As shown, the water supply and drainage connection device of the embodiment of the present invention is used for connecting a first pipe 1 and a second pipe 2, and the water supply and drainage connection device includes a first butt sleeve 3, a second butt sleeve 4, a sealing assembly 5 and a connection assembly 8.

[0041] The first butt joint sleeve 3 is sleeved on the outer wall of the first tube 1, and the first butt joint sleeve 3 is connected to one end of the first tube 1 close to the second tube 2, and one end of the first tube 1 close to the second tube 2 exceeds the first butt joint sleeve 3 to form a first butt joint portion. The section of the first tube 1 that exceeds the first butt joint sleeve 3 is regarded as the first butt joint portion, relative to the plug connector.

[0042] The second docking sleeve 4 is sleeved on the outer wall of the second tube 2, the second docking sleeve 4 is connected to one end of the second tube 2 close to the first tube 1, and one end of the second docking sleeve 4 close to the first tube 1 exceeds the second tube 2 to form a second docking portion sleeved with the first docking portion; the section of the second docking sleeve 4 that exceeds the second tube 2 is used as the second docking portion, and relative to the plug-in hole, the plug connector and the plug-in hole are plug-connected. At this time, the position where the first docking sleeve 3 and the second docking sleeve 4 abut against each other is staggered with the docking seam or docking gap between the first tube 1 and the second tube 2 in the axial direction of the pipeline. The first docking sleeve 3 and the second docking sleeve 4 can play a role in structural reinforcement of the connection part of the first tube 1 and the second tube 2, thereby improving the stability of the structure.

[0043] The sealing assembly 5 is arranged between the first butt sleeve 3 and the second butt sleeve 4, that is, the first butt sleeve 3 abuts against one end of the sealing assembly 5 to form a sealing structure, and the second butt sleeve 4 abuts against the other end of the sealing assembly 5 to form a sealing structure.

[0044] like Figure 2 As shown, the connection assembly 8 is used to connect the first butt sleeve 3 and the second butt sleeve 4, and make the first butt sleeve 3 and the second butt sleeve 4 abut against the sealing assembly 5, so as to connect and seal the first pipe 1 and the second pipe 2. The first butt sleeve 3 and the second butt sleeve 4 are connected together by the connection assembly 8, so as to prevent the first butt sleeve 3 and the second butt sleeve 4 from being displaced in the axial direction thereof, and ensure that the sealing assembly 5 and the corresponding butt sleeve are always in close contact, thereby improving the sealing performance.

[0045] The embodiment of the present invention can form a first docking portion and a second docking portion that are connected to each other between the first tube 1 and the second tube 2 by arranging the first docking sleeve 3 and the second docking sleeve 4. The docking positions of the first docking portion and the second docking portion are staggered with the docking positions of the first tube 1 and the second tube 2, which can strengthen the connection position and improve the stability and safety of the structure. The embodiment of the present invention can achieve the alignment sealing and connection of the first docking sleeve 3 and the second docking sleeve 4 by arranging the sealing component 5 and the connecting component 8, which is convenient to operate, more practical, and reduces the cost of operation and maintenance.

[0046] Some specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0047] like Figures 1 to 5 As shown, the water supply and drainage connection device of the embodiment of the present invention is used for connecting a first pipe 1 and a second pipe 2, and the water supply and drainage connection device includes a first butt sleeve 3, a second butt sleeve 4, a sealing assembly 5 and a connection assembly 8.

[0048] The first docking sleeve 3 is sleeved on the outer wall of the first tube 1, and the first docking sleeve 3 is connected to the end of the first tube 1 close to the second tube 2, and the end of the first tube 1 close to the second tube 2 exceeds the first docking sleeve 3 to form a first docking portion. The section of the first tube 1 that exceeds the first docking sleeve 3 is used as the first docking portion, relative to the plug connector. The second docking sleeve 4 is sleeved on the outer wall of the second tube 2, and the second docking sleeve 4 is connected to the end of the second tube 2 close to the first tube 1, and the end of the second docking sleeve 4 close to the first tube 1 exceeds the second tube 2 to form a second docking portion that is sleeved with the first docking portion; the section of the second docking sleeve 4 that exceeds the second tube 2 is used as the second docking portion, relative to the plug hole, and the plug connector and the plug hole are plug-connected.

[0049] Optionally, the outer wall surface of the first docking part (the outer wall surface of the first pipe 1) and the inner wall surface of the second docking part (the inner wall surface of the second docking sleeve 4) fit together, so that the pipe and the docking sleeve can form a mutual reinforcement structure, avoid radial misalignment, and improve the stability of the structure.

[0050] At this time, the position where the first butt sleeve 3 and the second butt sleeve 4 abut against each other is staggered with the butt seam or butt gap between the first pipe 1 and the second pipe 2 in the axial direction of the pipeline, and the first butt sleeve 3 and the second butt sleeve 4 can play a role in structural reinforcement of the connection part of the first pipe 1 and the second pipe 2, thereby improving the stability of the structure.

[0051] The sealing assembly 5 is arranged between the first butt sleeve 3 and the second butt sleeve 4, that is, the first butt sleeve 3 abuts against one end of the sealing assembly 5 to form a sealing structure, and the second butt sleeve 4 abuts against the other end of the sealing assembly 5 to form a sealing structure.

[0052] Specifically, the sealing assembly 5 includes a first seal and a second seal, the first seal is connected to one of the first docking sleeve 3 and the second docking sleeve 4, and the second seal is connected to the other of the first docking sleeve 3 and the second docking sleeve 4. For example, the first seal is connected to the end of the first docking sleeve 3, and the second seal is connected to the end of the second docking sleeve 4. The first seal is provided with a chamber corresponding to the second seal so that the first seal and the second seal are clamped.

[0053] When the first butt joint sleeve 3 and the second butt joint sleeve 4 are in contact with each other, the second seal can be clamped in the chamber of the first seal to achieve mutual clamping. At this time, multiple seals can be formed, one is the butt seal between the first seal and the second butt joint sleeve 4, and the other is the butt seal between the second seal and the first seal. The sealing structure is in a broken line shape, which increases the butt area of ​​the sealing structure and improves the sealing effect.

[0054] Furthermore, the first seal may not abut against the second butt sleeve 4, or the force applied by the connecting assembly 8 between the first butt sleeve 3 and the second butt sleeve 4 may be applied more between the first seal and the second seal. The first seal and the second seal may be made of different materials, for example, by adjusting the rigidity and wear resistance of the first seal and the second seal, the stability and service life of the sealing assembly 5 may be better improved.

[0055] In this embodiment, the structure of the sealing assembly 5 not only increases the firmness of the seal, but also disperses the pressure under high pressure, reduces the risk of the seal ring loosening, and ensures a long-term stable sealing effect. This structural design can greatly reduce the risk of leakage and is suitable for high-pressure and complex fluid delivery pipelines.

[0056] When the medium in the pipeline is under high pressure and has frequent pressure fluctuations, the cooperation between the first seal and the second seal can better play a role of buffering and protection, and prevent the seal ring from being frequently directly impacted or worn. This embodiment is particularly suitable for frequent vibration and high wear environments, so that the sealing assembly 5 remains stable during long-term use, effectively prolongs the service life of the sealing assembly 5, reduces the need for replacement and maintenance, and improves the overall reliability of the equipment.

[0057] Optionally, the second sealing member may be a waterproof filler.

[0058] In this embodiment, the length of the first docking portion in the axial direction of the first docking sleeve 3 is less than or equal to the sum of the lengths of the second docking portion and the sealing assembly 5 in the axial direction of the first docking sleeve 3. That is to say, when the first docking portion and the second docking portion are plugged into place, the first tube 1 and the second tube 2 can just abut together, or a certain length of gap can be reserved between the first tube 1 and the second tube 2 to avoid that the first docking portion and the second docking portion cannot have the sealing assembly 5 effectively abut and seal when the first tube 1 and the second tube 2 abut.

[0059] like Figure 2 and Figure 4 As shown, the connection assembly 8 is used to connect the first butt sleeve 3 and the second butt sleeve 4, and make the first butt sleeve 3 and the second butt sleeve 4 abut against the sealing assembly 5, so as to connect and seal the first pipe 1 and the second pipe 2. There are multiple connection assemblies 8, and the multiple connection assemblies 8 are arranged along the circumference of the first butt sleeve 3 and the second butt sleeve 4.

[0060] The connecting assembly 8 includes an insert rod 81, a sleeve 7 and a clamping block 84. The insert rod 81 is connected to one of the first docking sleeve 3 and the second docking sleeve 4, and the insert rod 81 extends along the axial direction of the first docking sleeve 3; the sleeve 7 is connected to the other of the first docking sleeve 3 and the second docking sleeve 4, and the insert rod 81 is inserted into the sleeve 7; the clamping block 84 (limiting member) is connected between the insert rod 81 and the sleeve 7 to prevent the insert rod 81 from detaching from the sleeve 7.

[0061] Among them, a support 6 can be provided at the end of the plug rod 81, and connected with the corresponding first docking sleeve 3 or second docking sleeve 4 through the support 6. The end of the plug rod 81 close to the plug sleeve 7 has a slide groove 82, and a block 84 is provided in the slide groove 82 and can slide in the slide groove 82 to extend out of the slide groove 82 or retract into the slide groove 82. A first elastic member 83 is also provided between the block 84 and the plug rod 81, and the first elastic member 83 is a spring. A telescopic rod 85 is provided in the slide groove 82, one end of the telescopic rod 85 is connected to the bottom of the bottom groove of the slide groove 82, and the other end of the telescopic rod 85 is connected to the block 84. The spring sleeve is provided on the telescopic rod 85. When the block 84 is pressed, the block 84 will retract into the slide groove 82, and the plug rod 81 can pass through the plug sleeve 7 smoothly. When the block 84 is released, the block 84 will extend out of the slide groove 82 under the action of the spring to prevent the plug rod 81 from detaching from the plug sleeve 7.

[0062] In order to facilitate the insertion of the insertion rod 81 into the insertion sleeve 7, one side of the block 84 is set to an inclined slope. When the insertion rod 81 is inserted into the insertion sleeve 7, as the block 84 approaches the insertion sleeve 7, the inclined surface on the block 84 is squeezed by the insertion sleeve 7, causing the block 84 to retract into the slide groove 82. When the block 84 moves to the other side of the insertion sleeve 7, the block 84 will pop out and prevent the insertion rod 81 from detaching from the insertion sleeve 7.

[0063] Furthermore, the connecting assembly 8 also includes a fixed plate 86, a sliding plate 87 and a second elastic member 88, the fixed plate 86 is fixed on the plug rod 81, the sliding plate 87 is sleeved on the plug rod 81 and can be moved along the length direction of the plug rod 81, the second elastic member 88 is arranged between the fixed plate 86 and the sliding plate 87, the sliding plate 87 and the block 84 are respectively located on both sides of the plug sleeve 7, wherein the second elastic member 88 is a spring.

[0064] In other words, when the first tube 1 and the second tube 2 frequently move closer to and away from each other in their axial direction due to high-pressure media or frequent pressure fluctuations, the relative movement between the fixed plate 86 and the sliding plate 87 can be used to compress the second elastic member 88 to modulate the relative movement of the first tube 1 and the second tube 2, reduce the amplitude and frequency of the relative movement of the first tube 1 and the second tube 2, reduce the load borne by the sealing assembly 5, stabilize the environment in which the sealing assembly 5 is located, and increase the service life of the sealing assembly 5.

[0065] In this embodiment, the first butt sleeve 3 and the second butt sleeve 4 are connected together by the connecting assembly 8 to prevent the first butt sleeve 3 and the second butt sleeve 4 from being displaced in the axial direction thereof, thereby ensuring that the sealing assembly 5 is always in close contact with the corresponding butt sleeve, thereby improving the sealing performance.

[0066] The flexible combination structure of the plug rod 81 and the plug sleeve 7 is adopted, and the automatic docking and fixing are realized through the cooperation of the clamp block 84 and the slide groove 82, which can quickly adapt to pipe interfaces of different shapes and sizes. It not only simplifies the installation process, but also improves the versatility and adaptability of the components, reduces the need for additional adapters, significantly reduces installation time and maintenance costs, and helps to deal with complex non-standard pipe connections.

[0067] This embodiment can realize quick repair without stopping the machine when the pipeline bursts or leaks. Through the quick locking structure of the plug rod 81 and the plug sleeve 7, the two ends of the problematic pipeline can be quickly connected without stopping the water supply or the machine, and the system can be repaired to ensure production continuity. In the emergency repair scenario, the response time is greatly shortened, the production loss is reduced, and the stable operation of the system is effectively guaranteed.

[0068] The water supply and drainage connection system of the embodiment of the present invention includes any of the water supply and drainage connection devices described above, a monitoring device 13, a controller, a power supply module and an alarm.

[0069] The monitoring device 13 includes a bracket, a weighing component 131, a water collecting box 12 and a sheath 9. The weighing component 131 is arranged on the bracket. The weighing component 131 includes a pressure sensor for detecting the weight supported above it. The bracket includes a bottom plate 11 and a vertical plate 10. The vertical plate 10 is provided with a guide groove 101, and the guide groove 101 extends in the vertical direction. The water collecting box 12 is provided with a guide block 121, and the guide block 121 is slidably arranged in the guide groove 101; the sheath 9 is sleeved on the circumferential outer side of the water supply and drainage connection device, and the lower part of the sheath 9 is provided with a through hole 91, and the through hole 91 corresponds to the water collecting box 12 up and down. The water collecting box 12 is supported on the weighing component 131, and the water collecting box 12 is arranged below the water supply and drainage connection device and the sheath 9 to collect leaked water.

[0070] The monitoring device 13 is used to collect and detect water leaking from the water supply and drainage connection device. The controller is used to obtain the signal of the weighing component 131 and control the alarm to sound an alarm. The power supply module is used to supply power to the controller, the alarm and the weighing component 131.

[0071] This embodiment integrates a pressure sensor, a controller and an alarm to form real-time water leakage monitoring. When a leak occurs, the system can quickly send out an alarm signal to achieve real-time monitoring of the sealing effect, prompt maintenance in time, and avoid the adverse effects of water leakage on production and the environment. This embodiment significantly improves the safety and controllability of the pipeline system, helps to deal with the leak in the early stage, and reduces the maintenance frequency and accident risks.

[0072] The following is an explanation based on the application in a specific example.

[0073] Example 1: In a large-scale chemical plant water supply and drainage system renovation project, the original pipe fittings of the water supply and drainage pipelines in the production area of ​​a chemical plant had poor sealing performance and frequent leakage problems, resulting in production interruptions and safety hazards. The renovation involved a drainage pipeline with a total length of 500 meters, requiring the sealing components to operate stably and have real-time monitoring functions.

[0074] The working process of the water supply and drainage connection system using this embodiment is as follows: During installation, the plug rod is inserted into the plug sleeve, and the block and the slide groove are automatically engaged to ensure a stable connection of the pipe fitting. The waterproof filler and the first sealing ring work together to form a double seal to maintain sealing in a high-pressure environment. The monitoring device monitors the sealing effect in real time. Once a leak is detected, the alarm immediately sounds an alarm to remind you to deal with it in time. In continuous testing, the sealing component performed stably, and the real-time monitoring system was able to give an alarm in time when there was an initial leak, ensuring the safety of the system and production continuity.

[0075] Example 2: During a temporary repair project for a burst water pipe in a factory's production workshop, the main water supply pipe in the production workshop suddenly burst, and a large amount of water leaked. Since the production equipment is in operation and cannot be shut down immediately, temporary repairs must be carried out without shutting down the equipment to prevent production interruptions. The water supply and drainage connection system of an embodiment of the present invention is used for emergency repairs. The temporary repair is carried out on the main water supply pipe interface with a diameter of 100 mm. It is required to complete the temporary closure of the burst interface without shutting down the water supply to ensure that the water flow continues to flow smoothly and avoid production losses caused by shutdowns.

[0076] The working process of the water supply and drainage connection system of this embodiment is as follows: First, simply clean the area around the burst interface and install the plug sleeve to fix it on one side of the damaged pipe interface. Insert the plug rod into the plug sleeve so that the block and the slide structure automatically engage to ensure a stable connection. The sealing ring and the waterproof filler form a double seal under the pressure of the running water to effectively prevent leakage. The entire maintenance process was completed without stopping the water supply or the machine, successfully suppressing the leakage at the burst point. During the subsequent 72 hours of operation, the sealing effect was stable and no new leakage occurred, which bought time for subsequent permanent maintenance and ensured the continuity of production.
