Description

Technical Field

[0001] This utility model relates to the field of pipeline corrosion prevention and insulation technology, and in particular to a novel leak-proof and heat-insulating pipe joint connection insulation device. Background Technology

[0002] As the requirements for pipeline transportation efficiency and safety in fields such as oil, natural gas, and district heating increase, and as the application scenarios of insulated pipelines in urban infrastructure construction become more diversified, traditional jointing technology can no longer meet actual needs. At the same time, the development of materials science and the progress of manufacturing processes have provided key support for breaking through the bottlenecks of traditional technologies, and have also promoted the research and development of new jointing connection insulation devices with excellent leak-proof performance, stability and adaptability.

[0003] The traditional insulation pipe joint connection device currently used relies on adjustable clamps or positioning rings to fix the joint position by connecting to the outer protective pipe of the insulation pipe. At the same time, high-viscosity hot melt sealing strips are used to seal the joint gaps. After sealing, the internal composite insulation layer, which consists of a high-density polyurethane foam layer and an aluminum foil reflective layer, is wrapped around the joint by mechanical pressure or on-site foaming. Special parts use segmented flexible insulation components to achieve insulation without dead corners, thus reducing heat loss through a dual effect.

[0004] The traditional insulation devices used for joint connections of insulated pipes currently in use can achieve insulation filling of joint connections, but they cannot achieve rapid installation of electrothermal fusion sleeves or rapid and accurate filling of foam material. Therefore, a new type of leak-proof insulation device for joint connections of insulated pipes is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a novel leak-proof insulation pipe joint connection insulation device, which aims to improve the problems of poor installation efficiency of electric heating sleeve and slow filling speed of foam material in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel leak-proof and heat-insulating pipe joint connection and insulation device includes an upper pressure plate. A rotating plate is fixedly connected to the bottom left side of the upper pressure plate. A rotating shaft is movably connected to the inner side of the rotating plate. Fixed plates are movably connected to the inner sides of both ends of the rotating shaft. A lower pressure plate is fixed to the bottom side of the fixed plate. An electrothermal fusion sleeve is slidably connected to the inner side of the upper pressure plate. A top plate is fixedly connected to the outer side of the electrothermal fusion sleeve. Multiple fixing grooves are opened on the inner side of the electrothermal fusion sleeve.

[0008] As a further description of the above technical solution:

[0009] A foaming nozzle is slidably connected to the top side of the upper pressure plate, a guide tube is fixedly connected to the top side of the foaming nozzle, an inlet pipe is fixedly connected to the rear end of the guide tube, a handle is rotatably connected to the top side of the inlet pipe, and a ball valve is fixedly connected to the bottom side of the handle.

[0010] As a further description of the above technical solution:

[0011] An adjusting plate is fixedly connected to the right side of both the upper and lower pressure plates. A bolt is threaded onto the inner side of the adjusting plate, and a turntable is fixedly connected to the top side of the bolt.

[0012] As a further description of the above technical solution:

[0013] Both the upper and lower pressure plates are fixedly connected to baffles on their left and right sides, and connecting blocks are slidably connected to the inner side of the baffles;

[0014] As a further description of the above technical solution:

[0015] The bottom side of the electrothermal sleeve is slidably connected to the inner side of the lower pressure plate, and the outer side of the top plate abuts against the inner side of the lower pressure plate;

[0016] As a further description of the above technical solution:

[0017] The left and right sides of the electrothermal sleeve are slidably connected to the inner side of the baffle, and the outer side of the electrothermal sleeve abuts against the inner side of the connecting block.

[0018] As a further description of the above technical solution:

[0019] The inner side of the fixed plate abuts against the outer side of the electrothermal sleeve, and the inner side of the rotating plate abuts against the outer side of the electrothermal sleeve.

[0020] As a further description of the above technical solution:

[0021] The outer side of the ball valve is rotatably connected to the inner side of the inlet pipe.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the bolt is driven to rotate in the adjustment plate by the turntable. With the opening and closing structure of the upper and lower pressure plates, the connecting block is driven to slide in the baffle to fix the position of the electrothermal sleeve. The device can be assembled without complicated disassembly, thereby reducing construction difficulty, saving manpower and time costs, and improving on-site operation efficiency.

[0024] 2. In this utility model, by coordinating the foaming nozzle with the integrated guide tube and inlet tube, the nozzle can be synchronously aligned with the gap of the filling and accurately deliver the foaming material without additional assembly or angle adjustment. This ultimately simplifies the component connection process, reduces the risk of component detachment, and directly improves the sealing performance of the filling. Attached Figure Description

[0032] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3This utility model provides an embodiment of a novel leak-proof insulation pipe joint connection insulation device, including an upper pressure plate 1. The upper pressure plate 1 serves as the upper core support component of the device, providing upper clamping force for the subsequently installed electrofusion sleeve 11, ensuring that the electrofusion sleeve 11 does not shift upwards during operation, and also protecting the upper part of the electrofusion sleeve 11 from external impact damage. A rotating plate 6 is fixedly connected to the bottom left side of the upper pressure plate 1, enabling the opening and closing of the upper pressure plate 1 and the lower pressure plate 2, facilitating the placement of the insulation pipe joint into the device. Simultaneously, the rotating plate 6 can also... The rotating plate 6 serves as a preliminary limit on the left side of the electrothermal sleeve 11. A rotating shaft 5 is movably connected to the inner side of the rotating plate 6, allowing the rotating plate 6 to rotate flexibly around the shaft 5. This prevents jamming when the rotating plate 6 is connected to other components, ensuring smooth opening and closing of the upper pressure plate 1. Simultaneously, the rotating shaft 5 connects the left and right rotating plates 6, ensuring synchronous rotation on both sides. Fixed plates 7 are movably connected to the inner sides of both ends of the rotating shaft 5, connecting the rotating shaft 5 to the lower pressure plate 2. This allows the upper pressure plate 1, rotating plate 6, rotating shaft 5, and lower pressure plate 2 to form a complete system. The device features an openable structure. A lower pressure plate 2 is fixed to the bottom side of the fixed plate 7. The lower pressure plate 2 serves as the core lower support component of the device, corresponding vertically to the upper pressure plate 1. Together, they form a clamping space to hold the electrofusion sleeve 11 and the insulation pipe patch. Simultaneously, the lower pressure plate 2 provides lower support for the electrofusion sleeve 11, preventing it from shifting downwards due to its own weight or working pressure. The electrofusion sleeve 11 is slidably connected to the inner side of the upper pressure plate 1. This sliding connection allows operators to adjust the position of the electrofusion sleeve 11 according to the actual size of the insulation pipe patch, ensuring the proper functioning of the device. The heat-fusion sleeve 11 can be precisely fitted onto the insulation pipe joint. The outer side of the heat-fusion sleeve 11 is fixedly connected to a top plate 12 to prevent excessive displacement of the heat-fusion sleeve 11 when sliding between the upper pressure plate 1 and the lower pressure plate 2. Multiple fixing grooves 13 are opened on the inner side of the heat-fusion sleeve 11. When the heat-fusion sleeve 11 is energized and melted, the molten material will fill the fixing grooves 13. After cooling, the fixing grooves 13 can make the connection between the heat-fusion sleeve 11 and the insulation pipe joint more secure, effectively preventing the heat-fusion sleeve 11 from separating from the insulation pipe due to thermal expansion and contraction in the later stage, and further improving the leak-proof effect.

[0034] Reference Figures 4-5A foaming nozzle 14 is slidably connected to the top side of the upper pressure plate 1. The function of the foaming nozzle 14 is to spray foamed insulation material into the gap between the electrothermal jacket 11 and the insulation pipe interface. A guide pipe 15 is fixedly connected to the top side of the foaming nozzle 14. The guide pipe 15 is the conveying channel for the foamed insulation material, which can accurately guide the foamed material delivered from the subsequent inlet pipe 17 into the foaming nozzle 14. The inlet pipe 17 is fixedly connected to the rear end of the guide pipe 15. The operator can connect the pipe for supplying external foamed material to the inlet pipe 17 to allow the foamed material to pass through. The inlet pipe 17 enters the guide pipe 15. At the same time, the inlet pipe 17 can also play a preliminary pressure stabilizing role for the foaming material to ensure stable material delivery. The top side of the inlet pipe 17 is rotatably connected to the handle 18. By rotating the handle 18, the operator can drive the ball valve 16 below to rotate, thereby controlling the flow of foaming material in the inlet pipe 17. The bottom side of the handle 18 is fixedly connected to the ball valve 16. When the operator rotates the handle 18, the ball valve 16 will rotate accordingly. When the channel of the ball valve 16 is aligned with the channel of the inlet pipe 17, the foaming material can pass through smoothly.

[0035] Reference Figures 1-5Adjusting plates 8 are fixedly connected to the right sides of both the upper pressure plate 1 and the lower pressure plate 2. The adjusting plates 8 are key components for adjusting the clamping force between the upper pressure plate 1 and the lower pressure plate 2. Bolts 9 are subsequently installed inside the adjusting plates 8, with threaded connections. These threaded connections provide adjustability and self-locking. By rotating the bolts 9, the two adjusting plates 8 can be moved closer or further apart, thus changing the opening degree of the upper pressure plate 1 and the lower pressure plate 2. Simultaneously, the threaded connections allow the bolts 9 to be fixed in a designated position, preventing the adjusting plates 8 from loosening during operation. The top side of the bolts 9... A turntable 10 is fixedly connected, increasing the force-bearing area when the operator rotates the bolt 9. Compared to directly rotating the bolt 9, rotating the turntable 10 requires less effort. Baffles 3 are fixedly connected to both sides of the upper pressure plate 1 and the lower pressure plate 2. These baffles 3 limit the movement of the electrofusion sleeve 11 from both sides. A connecting block 4 is slidably connected to the inner side of the baffle 3, adjusting its position according to the width of the electrofusion sleeve 11. When the inner side of the connecting block 4 abuts against the outer side of the electrofusion sleeve 11, it further enhances the fixing effect of the electrofusion sleeve 11, preventing electric shock. The heat-fusion sleeve 11 wobbles in the left-right direction. The bottom side of the heat-fusion sleeve 11 is slidably connected to the inner side of the lower pressure plate 2, and the outer side of the top plate 12 abuts against the inner side of the lower pressure plate 2, preventing the heat-fusion sleeve 11 from moving excessively upwards. Furthermore, the contact between the top plate 12 and the lower pressure plate 2 can transmit the supporting force of the lower pressure plate 2 to the heat-fusion sleeve 11. Both sides of the heat-fusion sleeve 11 are slidably connected to the inner side of the baffle 3, allowing the heat-fusion sleeve 11 to move in the front-back direction under the restriction of the baffle 3. The outer side of the heat-fusion sleeve 11 abuts against the inner side of the connecting block 4, and the inner side of the fixing plate 7 abuts against the outer side of the heat-fusion sleeve 11, enhancing the structural stability of the left side of the device. To ensure the overall device is more reliable during operation, the inner side of the rotating plate 6 abuts against the outer side of the electrothermal sleeve 11, and the abutting action of the rotating plate 6 and the fixed plate 7 are superimposed to make the left side of the electrothermal sleeve 11 more secure. At the same time, when the rotating plate 6 closes with the upper pressure plate 1, its abutting action can also guide the electrothermal sleeve 11 to automatically adjust to the center position of the device, reducing the workload of the staff in adjusting the position of the electrothermal sleeve 11. The outer side of the ball valve 16 is rotatably connected to the inner side of the inlet pipe 17 to prevent the foaming material from leaking from the connection gap between the ball valve 16 and the inlet pipe 17, ensuring that the foaming material can be completely delivered to the guide pipe 15 and the foaming nozzle 14, thereby improving the material utilization rate.

[0036] Working principle: First, the upper pressure plate 1 is opened by the rotating structure composed of the rotating plate 6 and the rotating shaft 5, and the part of the insulation pipe to be treated is placed on the lower pressure plate 2. Then, the upper pressure plate 1 is closed, so that the repair section is completely wrapped in the clamping space formed by the upper pressure plate 1 and the lower pressure plate 2. The electrothermal fusion sleeve 11 is slid in from the inside of the upper pressure plate 1, so that it is accurately fitted on the outside of the insulation pipe repair section. The left and right baffles 3 and the connecting blocks 4 that slide in them limit and clamp the electrothermal fusion sleeve 11 from both sides to prevent it from moving horizontally. The bottom side of the electrothermal sleeve 11 is slidably connected to the lower pressure plate 2, while the top is limited by the top plate 12 to prevent vertical movement. The rotating plate 6 and the fixed plate 7 abut against the electrothermal sleeve 11 from the left side to further enhance its positioning stability. Then, the bolt 9 in the rotating adjusting plate 8 is rotated, and the clamping force between the upper and lower pressure plates 2 is adjusted effortlessly through the turntable 10, so that the electrothermal sleeve 11 fits tightly against the joint. The electrothermal sleeve 11 is heated by electricity to melt it and bond it to the joint of the insulation pipe, which significantly enhances the leak prevention capability and connection strength.

[0037] Connect the external foaming equipment to the inlet pipe 17, rotate the handle 18 to open the ball valve 16, and the foaming material is transported to the foaming nozzle 14 through the inlet pipe 17 and the guide pipe 15, and injected into the gap between the electrothermal fusion sleeve 11 and the interface of the insulation pipe. After the foaming and curing, the insulation performance is restored. After the electrothermal fusion sleeve 11 cools down and the foaming material cures, loosen the bolt 9, open the upper pressure plate 1, and the treated insulation pipe can be taken out, completing the integrated leak prevention and insulation joint repair construction.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
