Description

Technical Field

[0001] This utility model relates to the field of compressor pipeline connection technology, specifically a high-temperature and high-pressure resistant pipeline connection component for compressors. Background Technology

[0002] During operation, especially in fields such as chemical engineering, refrigeration, and power engineering, the gases or media discharged by compressors often have the characteristics of high temperature and high pressure.

[0003] Pipeline connection assemblies, which connect compressors to subsequent pipelines, are subjected to harsh conditions of high temperature and high pressure over long periods, making them prone to the following problems: First, traditional flange or threaded connections exhibit significant differences in thermal expansion at high temperatures. The sealing interface of traditional connections is susceptible to gaps due to these expansion differences, leading to leaks and posing safety hazards. Second, the high-temperature medium within the pipeline can raise the temperature of the connection assembly itself, accelerating material fatigue and potentially affecting surrounding equipment or the operating environment. Furthermore, existing connection assemblies lack effective cooling structures, failing to actively cool the connection points and resulting in a shortened service life. Additionally, traditional connection methods are cumbersome to disassemble and maintain, requiring specialized tools and making it difficult to guarantee alignment accuracy and sealing reliability after repeated disassembly and reassembly.

[0004] Therefore, how to design a pipe connection assembly that is resistant to high temperature and high pressure, has reliable connection, good cooling effect, and is easy to disassemble and assemble has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] The purpose of this utility model is to provide a high-temperature and high-pressure resistant pipe connection assembly for compressors, which has the advantages of reliable connection, high temperature and high pressure resistance, good cooling effect and convenient disassembly and assembly, and solves the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-temperature and high-pressure resistant pipe connection assembly for a compressor includes a central pipe, connecting pipes fixed to both ends of the central pipe, an internally threaded cylinder fixed to the outer peripheral wall of the connecting pipe, a first mounting cylinder movably disposed on the inner wall of the internally threaded cylinder, a long pipe fixed to the inner wall of the first mounting cylinder, an inner pipe fixed to the inner wall of the long pipe, a bent pipe installed on the end of the first mounting cylinder away from the central pipe, a threaded locking mechanism disposed between the internally threaded cylinder and the first mounting cylinder, a docking assembly disposed on the end of the inner pipe near the central pipe, an insertion positioning unit disposed on the first mounting cylinder, a high-temperature resistant mechanism disposed on the outer peripheral wall of the central pipe, and a water inlet / outlet mechanism disposed on the high-temperature resistant mechanism. A gap is provided between the outer peripheral wall of the inner tube and the inner wall of the central tube; The threaded locking mechanism is used to lock and fix the first mounting cylinder inside the internal threaded cylinder; The mating assembly is used to seal and connect the ends of two adjacent inner tubes; The insertion positioning unit is used to limit the relative circumferential position of two adjacent first mounting cylinders; The high-temperature resistant mechanism is used to cool the central tube; The water inlet / outlet mechanism is used to supply or discharge cooling medium to high-temperature resistant components.

[0007] Preferably, the threaded locking mechanism includes a second mounting cylinder threaded onto the inner wall of the internal threaded cylinder, a plurality of fixed posts fixed to the end of the second mounting cylinder away from the central tube, and an arc-shaped block fixed to the end of the plurality of fixed posts away from the central tube; the inner wall of the second mounting cylinder is also threaded onto the outer peripheral wall of the first mounting cylinder; the arc-shaped block is an arc-shaped plate structure with its inner arc surface facing the outer peripheral wall of the first mounting cylinder.

[0008] It is worth noting that by setting up a second mounting cylinder, the outer wall of which is threadedly connected to the inner threaded cylinder, and the inner wall of which is threadedly connected to the first mounting cylinder, a double threaded locking structure is formed. With the help of the fixing column and the arc-shaped block, the operator only needs to rotate the arc-shaped block to drive the second mounting cylinder to rotate, thereby firmly locking the first mounting cylinder inside the inner threaded cylinder. No additional tools are required, and the assembly and disassembly are convenient. The inner arc surface design of the arc-shaped block makes it easy to apply force with fingers, and at the same time, it plays a limiting role to prevent over-tightening.

[0009] Preferably, the docking assembly includes a connecting tube fixed to one end of the inner tube near the central tube, wherein a limiting tube is fixed to the inner wall of one of the connecting tubes, and the outer peripheral wall of the limiting tube is in contact with the inner wall of the other connecting tube near the central tube; the outer diameter of the limiting tube is equal to the inner diameter of the connecting tube, and the axial length of the limiting tube is greater than the axial length of the connecting tube.

[0010] It is worth noting that when two adjacent first mounting cylinders are aligned through the plug-in positioning unit, the connecting pipes at the ends of the two inner tubes approach each other, and the limiting tube on one side is inserted into the inner wall of the connecting pipe on the other side. Since the outer diameter of the limiting tube is equal to the inner diameter of the connecting pipe, a precise fit is achieved, which effectively prevents media leakage. The axial length of the limiting tube is greater than that of the connecting pipe, ensuring that the insertion depth is sufficient and that a reliable sealing connection can be maintained even if there is a certain amount of thermal expansion or vibration.

[0011] Preferably, the insertion positioning unit includes multiple insertion holes opened at the end of the connecting tube away from the central tube and multiple insertion posts fixed to the end of the first mounting cylinder near the central tube. The insertion posts are adapted to the insertion holes on the connecting tube. The multiple insertion holes are evenly distributed along the circumference of the connecting tube, and the multiple insertion posts are evenly distributed along the circumference of the first mounting cylinder, and the positions of the insertion posts and insertion holes correspond one-to-one.

[0012] It is worth noting that during installation, the insert at the end of the first mounting cylinder is directly inserted into the corresponding insertion hole at the end of the connecting pipe. The circumferentially evenly distributed design ensures balanced force distribution and prevents the first mounting cylinder from rotating relative to the central pipe, thereby ensuring precise coaxial connection between the connecting pipe and the limiting pipe, and also enhancing the torsional strength of the entire connecting assembly.

[0013] Preferably, the high-temperature resistant mechanism includes two fixed discs fixed to the outer peripheral wall of the central tube and multiple cold water pipes fixed to the two fixed discs through the tube; the fixed discs are annular discs, with their inner rings fixedly connected to the outer peripheral wall of the central tube, and the multiple cold water pipes are evenly arranged through the circumference of the fixed discs.

[0014] It is worth noting that the fixed plate stably fixes the cold water pipes to the periphery of the central pipe. Multiple cold water pipes are evenly distributed around the circumference, forming a cooling tube bundle around the central pipe. When the high-temperature medium flows through the central pipe, the heat is transferred to the cooling medium in the cold water pipe through the pipe wall, realizing efficient heat exchange, significantly reducing the temperature of the central pipe and the entire connecting assembly, and improving the high-temperature resistance and service life.

[0015] Preferably, the water inlet and outlet mechanism includes a hollow box fixed to the ends of multiple cold water pipes on the same side, a fixed pipe fixed through the side wall of the hollow box, and a valve body disposed on the fixed pipe; two hollow boxes are provided, which are respectively fixed to the two ends of multiple cold water pipes; the hollow box has a flat box structure, and its internal cavity is connected to the ends of all cold water pipes, and the fixed pipe is connected to the internal cavity of the hollow box.

[0016] It is worth noting that the hollow box acts as a flow distributor, connecting multiple cold water pipes in parallel. The cooling medium enters the hollow box from one side of the fixed pipe, is evenly distributed to each cold water pipe, flows through the periphery of the central pipe and then merges into the hollow box on the other side, and is discharged through the fixed pipe on the other side, forming a complete cooling circulation loop. The valve body is used to control the on / off state and flow rate of the cooling medium, and the cooling intensity can be flexibly adjusted according to the actual working conditions.

[0017] Preferably, the valve body is a manually operated shut-off valve or an electrically controlled valve.

[0018] It is worth noting that manual shut-off valves are suitable for on-site manual adjustment and have a lower cost; electric control valves can be linked with the compressor control system to automatically start and stop or adjust the cooling water flow according to the exhaust temperature, thus improving the intelligence level of the device.

[0019] Preferably, the bend is L-shaped and the bend is threaded to the first mounting cylinder.

[0020] It is worth noting that the L-shaped bend can change the direction of the pipeline to adapt to the spatial layout requirements of the compressor outlet and external pipelines. The threaded connection method makes it easy to replace bends of different angles or to disassemble and maintain them.

[0021] Preferably, the gap between the outer peripheral wall of the inner tube and the inner wall of the central tube is 0.5 mm to 2 mm.

[0022] It is worth noting that this gap not only ensures the thermal expansion margin between the inner tube and the central tube, preventing them from being squeezed and deformed at high temperatures, but also forms an air insulation layer, further blocking the direct conduction of high temperature from the inner tube to the central tube, thus improving the overall insulation effect.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model achieves double thread locking between the first mounting cylinder and the internal threaded cylinder by setting a threaded locking mechanism (second mounting cylinder, fixed column and arc block), which solves the problem of inconvenient disassembly and assembly and the need for special tools in traditional flange connections. Operators only need to manually turn the arc block to complete the locking or loosening. Disassembly and assembly are quick and do not require auxiliary tools. At the same time, the double thread structure ensures the reliability of the connection under high pressure conditions and effectively prevents loosening and leakage. 2. This utility model achieves precise sealing and circumferential positioning of the ends of two adjacent inner pipes by setting up a docking component (butt joint and limiting pipe) and a plug positioning unit (plug hole and plug post). It solves the problems of difficult centering and unreliable sealing when connecting multiple pipe sections. The tight fit between the limiting pipe and the butt joint forms a reliable sealing interface, and the fit between the plug post and the plug hole ensures that the components do not rotate relative to each other during installation, thereby ensuring centering accuracy and vibration resistance under long-term use. 3. This utility model, by setting up a high-temperature resistant mechanism (fixed plate and multiple cold water pipes) and an inlet / outlet water mechanism (hollow box, fixed pipe and valve body), forms an active cooling circuit around the central pipe, which solves the problems of excessive temperature and easy aging of materials in existing connecting components under high-temperature media. When the cooling medium flows through the cold water pipe, it can efficiently remove the heat transferred by the central pipe, significantly reducing the operating temperature of the component. At the same time, the gap between the inner pipe and the central pipe plays the auxiliary role of the air insulation layer, further improving the high-temperature resistance and extending the service life of the component.

[0027] To address the problems of unreliable connections, inconvenient assembly and disassembly, poor high-temperature and high-pressure resistance, and lack of active cooling structures in existing technologies, the following technical solution is proposed. Please refer to [link / reference needed].

[0029] In this embodiment, specifically, the docking assembly includes a connecting tube 16 fixed to one end of the inner tube 15 near the central tube 1. A limiting tube 18 is fixed to the inner wall of one of the connecting tubes 16, and the outer peripheral wall of the limiting tube 18 is in contact with the inner wall of the other connecting tube 16 near the central tube 1. The outer diameter of the limiting tube 18 is equal to the inner diameter of the connecting tube 16, and the axial length of the limiting tube 18 is greater than the axial length of the connecting tube 16.

[0030] In this embodiment, specifically, the insertion positioning unit includes multiple insertion holes opened at the end of the connecting tube 2 away from the central tube 1 and multiple insertion posts 17 fixed to the end of the first mounting cylinder 4 near the central tube 1. The insertion posts 17 are adapted to the insertion holes on the connecting tube 2. The multiple insertion holes are evenly distributed along the circumference of the connecting tube 2, and the multiple insertion posts 17 are evenly distributed along the circumference of the first mounting cylinder 4, and the positions of the insertion posts 17 and the insertion holes correspond one-to-one.

[0031] In this embodiment, specifically, the high-temperature resistant mechanism includes two fixed disks 7 fixed to the outer peripheral wall of the central tube 1 and multiple cold water pipes 8 fixed to the two fixed disks 7 in a through manner; the fixed disk 7 is a circular disk body, the inner ring of which is fixedly connected to the outer peripheral wall of the central tube 1, and the multiple cold water pipes 8 are evenly arranged through the fixed disk 7 in a circumferential manner.

[0032] In this embodiment, specifically, the water inlet and outlet mechanism includes a hollow box 9 fixed to the ends of multiple cold water pipes 8 on the same side, a fixed pipe 10 fixed to the side wall of the hollow box 9, and a valve body 11 disposed on the fixed pipe 10; there are two hollow boxes 9, which are respectively fixed to the two ends of multiple cold water pipes 8; the hollow box 9 has a flat box structure, and its internal cavity is connected to the ends of all cold water pipes 8, and the fixed pipe 10 is connected to the internal cavity of the hollow box 9.

[0033] In this embodiment, specifically, the valve body 11 is a manual shut-off valve or an electric control valve.

[0034] In this embodiment, specifically, the bend 6 is L-shaped, and the bend 6 and the first mounting cylinder 4 are connected by threads.

[0035] In this embodiment, specifically, the gap between the outer peripheral wall of the inner tube 15 and the inner wall of the central tube 1 is 0.5mm to 2mm.

[0036] Working principle: When in use, first connect the two bends 6 to the compressor piping system respectively (for example, one bend 6 is connected to the compressor exhaust port, and the other bend 6 is connected to the downstream pipeline or cooler inlet). The bends 6 are connected to the first mounting cylinder 4 by threads. The orientation of the bends 6 can be selected according to the site space. When installing this component, the first mounting cylinders 4 on both sides are inserted into the corresponding internal threaded cylinders 3 from both ends of the central tube 1. During the insertion process, the multiple insertion posts 17 of the first mounting cylinder 4 near the end of the central tube 1 are aligned with the corresponding insertion holes of the connecting tube 2 away from the end of the central tube 1 and pushed in. The insertion positioning unit restricts the circumferential rotation of the first mounting cylinder 4 relative to the central tube 1, ensuring the alignment accuracy. At the same time, the docking components at the ends of the two inner tubes 15 cooperate with each other. The limiting tube 18 on one inner tube 15 is inserted into the inner wall of the connecting tube 16 on the other inner tube 15. Since the outer diameter of the limiting tube 18 is equal to the inner diameter of the connecting tube 16, a tight sealing interface is formed. Subsequently, the arc-shaped blocks 14 on both sides are rotated respectively, and the second mounting cylinder 12 is rotated through the fixed column 13. The external thread of the second mounting cylinder 12 engages with the internal thread of the internal thread cylinder 3, and at the same time, the internal thread of the second mounting cylinder 12 engages with the external thread of the first mounting cylinder 4. The cylinder is continuously tightened until the inner arc surface of the arc-shaped block 14 presses against the outer peripheral wall of the first mounting cylinder 4, thereby firmly locking the first mounting cylinder 4 into the internal thread cylinder 3 and completing the connection. When the compressor is running, the high-temperature and high-pressure medium enters from the bend 6 on one side, flows through the first mounting cylinder 4, the long pipe 5, and the inner pipe 15 on that side, and then enters the inner pipe 15, the long pipe 5, and the first mounting cylinder 4 on the other side through the docking assembly, and finally exits from the bend 6 on the other side; when the medium flows through the inner pipe 15, the heat is transferred through the wall of the inner pipe 15 to the long pipe 5 and the first mounting cylinder 4, and some of the heat is further transferred to the central pipe 1; At this time, cooling medium is introduced into the high-temperature resistant mechanism through the water inlet and outlet mechanism: the cooling medium enters the hollow box 9 on one side through the fixed pipe 10 on one side, and is evenly distributed into multiple cold water pipes 8. The cold water pipes 8 are arranged around the central pipe 1. The medium absorbs the heat of the central pipe 1 during the flow process. After the temperature rises, it flows into the hollow box 9 on the other side, and is discharged through the fixed pipe 10 on the other side, forming a circulating cooling. At the same time, the 0.5mm to 2mm gap between the outer peripheral wall of the inner pipe 15 and the inner wall of the central pipe 1 acts as an air insulation layer, reducing the direct conduction of heat. When disassembly and maintenance are required, rotate the arc-shaped block 14 in the opposite direction to disengage the second mounting cylinder 12 from the internal threaded cylinder 3 and the first mounting cylinder 4. Then, the first mounting cylinder 4, together with the inner tube 15, can be pulled out from the central tube 1. The operation is simple and quick and requires no tools.
