Description

Technical Field

[0001] This utility model relates to the field of nickel alloy forging valve body technology, and in particular to a nickel-based alloy forging. Background Technology

[0002] Forging is a core processing technology that uses forging machinery to apply pressure to a metal billet, causing it to undergo plastic deformation, thereby obtaining forgings with specific mechanical properties, shapes, and dimensions. In the machinery field, for critical components subjected to high loads and harsh working conditions, most rely on forgings for manufacturing, except for simple-shaped components that can be made from rolled plates, profiles, or welded parts. These components often have extremely high requirements for the fatigue resistance, physical properties, and mechanical properties of the materials. For example, the processing quality of valve bodies, which are subjected to high pressure conditions for extended periods, directly affects the operational stability and safety of the entire equipment system. Currently, the industry typically selects forgings with high density... Copper alloys with excellent corrosion resistance are used as the core forging material for valve body forgings to meet their demanding operating conditions. Early traditional valve body forgings had relatively simple structural designs. In the critical hole-making process, additional hole-setting devices were needed to repeatedly adjust the hole position before subsequent hole-making operations could be performed to meet process standards. This processing method had significant inefficiency. In practical applications, traditional valve body forgings also revealed drawbacks such as poor sealing, inconvenient disassembly and assembly, and poor installation flexibility, which seriously affected their practicality and adaptability to different scenarios, making it difficult to meet the modern industrial demand for efficient and reliable valve body components. To address some of the shortcomings of traditional valve body forgings, Chinese patent CN216666610U discloses a nickel alloy bowl-shaped valve body forging. This forging utilizes a rubber ring in the top circular groove and a sealing ring in the bottom sealing groove to clamp the outer wall of the extended end of the long tube, achieving locking and positioning of the extended end. Simultaneously, the design, which uses a clamping plate for fixing and a screw for tightening to compress the outer wall of the extended end, optimizes positioning convenience during opening operations, improves sealing performance, and offers advantages such as space saving and good fastening effect. However, the existing technical solution still has obvious limitations in practical applications: On the one hand, the connection between the forged main pipe and the external pipeline still uses the traditional flange or threaded connection. In scenarios that require frequent disassembly and assembly, frequent twisting of the bolts at the threads or flange can easily lead to thread wear. Moreover, the threads are prone to corrosion after long-term use. Even if there is no corrosion, the threads may become stuck or stripped due to the adhesion of impurities, which seriously affects the efficiency of rapid disassembly and assembly. On the other hand, the forged main pipe lacks a special support and reinforcement structure, making it difficult to obtain stable support during use. The overall stability is poor, and it is prone to deformation and bending when subjected to external impact, which in turn affects the sealing performance and service life of the valve body. In summary, the existing valve body forging technology still has defects and deficiencies, and further design improvements are urgently needed. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes a nickel-based alloy forging to more precisely resolve the problems described above.

[0004] This utility model is achieved through the following technical solution: This utility model proposes a nickel-based alloy forging, including a nickel-based alloy forging main pipe and a nickel-based alloy forging side connector. Both ends of the outer surface of the nickel-based alloy forging main pipe are fixedly installed with elastic clamping mechanisms, and both ends of the nickel-based alloy forging main pipe are fixedly installed with plug connectors. A support mechanism is movably sleeved on the outer surface of the nickel-based alloy forging main pipe. The nickel-based alloy forging side connector is sleeved and installed on the outer surface of the plug connector through the elastic clamping mechanism. An external pipe is welded and installed on the outside of the nickel-based alloy forging side connector. The elastic clamping mechanism includes an annular rail and a limiting arc sleeve. The annular rail is integrally formed and disposed at both ends of the outer surface of the main tube of the nickel-based alloy forging. A limiting spring is installed inside the annular rail by screws. An arc-shaped slider is fixedly connected to the outer end of the limiting spring. The arc-shaped slider is slidably connected to the inside of the annular rail. A clamping arm is fixedly installed on the outer side of the arc-shaped slider. An arc-shaped locking pin is fixedly installed on the outer side of the clamping arm. The limiting arc sleeves are arranged in an evenly spaced ring and welded to the outer surface of the side joint of the nickel-based alloy forging. The end of the arc-shaped locking pin is inserted into the inside of the limiting arc sleeve. The limiting spring can be adjusted to compress the arc-shaped slider at the beginning of installation. The limiting spring contracts and stores potential energy. At this time, the arc-shaped locking pin rotates accordingly with the arc-shaped slider. During installation, the nickel-based alloy forging side joint and the plug joint are interlocked. At this time, the limiting arc sleeve is located at the arc-shaped locking pin. When the compression of the limiting spring is released, the limiting spring resets and pushes the arc-shaped slider to rotate in an arc along the arc-shaped sleeve track, so that the arc-shaped locking pin is inserted into the limiting arc sleeve to lock and limit the nickel-based alloy forging side joint. When disassembly is required, simply readjust the rotation of the support mechanism to make the arc-shaped locking pin disengage from the limiting arc sleeve.

[0005] Furthermore, a sealing gasket is provided between the plug and the nickel-based alloy forging side connector. The sealing gasket is placed at the gap after the nickel-based alloy forging main pipe and the nickel-based alloy forging side connector are fitted and sealed. The sealing gasket is used to play a preliminary sealing role.

[0006] Furthermore, a reinforcing sealing sleeve is fixedly connected to one side of the sealing gaskets that are close to each other. The reinforcing sealing sleeve is fitted onto the outer surface of the connector. A reinforcing sealing inner ring is fixedly connected to the inner side of the nickel-based alloy forging side connector. The reinforcing sealing inner ring is inserted into the inner side of the connector. The reinforcing sealing sleeve is used to further enhance the seal. At the same time, the reinforcing sealing inner ring is used to internally reinforce and support the connection between the connector and the nickel-based alloy forging side connector, ensuring that they have high strength after docking.

[0007] Furthermore, the support mechanism includes an outer slip ring that slides on the outer surfaces of two annular sleeves. The inner side of the outer slip ring is fixedly connected to the outer side of the arc-shaped slider. A support sleeve is fixedly installed between the inner sides of the outer slip ring. The support sleeve is used to sleeve the main tube of the reinforced nickel-based alloy forging to enhance its overall strength. At the same time, the overall surface of the support sleeve is relatively rough. When it is necessary to disassemble or install the side joint of the nickel-based alloy forging, the outer slip ring can be adjusted to drive the slider to compress the limiting spring, thereby causing the arc-shaped locking pin to disengage from the limiting arc sleeve and achieving disassembly and assembly.

[0008] Furthermore, the support mechanism also includes a support ring rail, which is welded to the middle of the outer surface of the support sleeve. The support ring rail has an inner sliding ring that can be rotatably installed inside. A support slider is welded to the bottom of the inner sliding ring, and a telescopic support leg is welded to the bottom of the support slider. The support ring rail and the inner sliding ring are used to slide against each other to achieve pre-adjustment of the support direction of the telescopic support leg, which facilitates flexible installation and assembly of the forging for support.

[0009] Furthermore, the retractable outrigger includes a main outrigger, which is fixedly connected to the bottom of the support slider. A support frame is movably connected to the outer surface of the main outrigger. A limit screw is threaded to the upper end of one side of the support frame. The end of the limit screw passes through the support frame. The main outrigger and the support frame cooperate to slide and flexibly adjust the length of the retractable outrigger, which is convenient and flexible to adapt to different installation applications. The limit screw is used to lock and fix the main outrigger and the support frame after adjustment of the retraction.

[0010] Furthermore, the outer surface of the main support leg is provided with equally spaced limit holes, and the end of the limit screw is inserted into the inner side of the limit hole. The limit screw is a hand-tightening screw and has a hexagonal bolt hole on its outer side. A support mounting main board is welded to the bottom of the support frame. Mounting holes are provided at the four corners of the support mounting main board. The spacing of the limit holes on the outer surface of the main support leg can be flexibly selected according to specific needs. At the same time, if more precise telescopic adjustment is required, a corresponding anti-slip joint can be set or the limit screw can use a finer thread to achieve more precise spacing adjustment. The limit hole is just one implementation method, and its spacing can be set according to needs. At the same time, the outer end of the limit screw can be threaded to place a loose screw for further reinforcement. The hexagonal bolt hole is used to insert a wrench into it for disassembly and assembly. If it cannot be tightened by hand, a wrench can be used for disassembly and assembly.

[0011] The beneficial effects of this utility model are: 1. During the application of this technical solution, the flexible clamping mechanism enables the quick installation and disassembly of the nickel-based alloy forging side joint and the main pipe, eliminating the need for traditional flange or threaded connection methods. This improves the efficiency of disassembly and assembly, solving the problems of thread wear, corrosion, jamming, or stripping caused by frequent disassembly and assembly in the prior art. At the same time, by setting up multiple sealing-related structures, the sealing performance of the forging connection can be enhanced, thus achieving a good sealing effect and solving the problem of poor sealing performance of valve body forgings in the prior art. 2. During the application of this technical solution, the support mechanism provides stable support and strength enhancement for the main tube of the nickel-based alloy forging during use. The support direction and height can be flexibly adjusted according to the installation scenario, thereby improving the overall stability and adaptability of the forging. This solves the problems of lack of support and reinforcement structure, poor stability, and easy deformation and bending of the main tube of the forging in the prior art. At the same time, the support mechanism and the elastic clamping mechanism work together to further ensure the reliability of the forging during use, thereby extending the service life of the forging and solving the problem of easy damage to the forging due to structural defects in the prior art.

[0014] 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. Example 1

[0015] A nickel-based alloy forging includes a nickel-based alloy forging main pipe 1 and a nickel-based alloy forging side connector 2. Both ends of the outer surface of the nickel-based alloy forging main pipe 1 are fixedly installed with elastic clamping mechanisms 3. Both ends of the nickel-based alloy forging main pipe 1 are fixedly installed with plug connectors 4. The outer surface of the nickel-based alloy forging main pipe 1 is movably fitted with a support mechanism 6. The nickel-based alloy forging side connector 2 is fitted onto the outer surface of the plug connector 4 through the elastic clamping mechanism 3. An external pipe 5 is welded to the outside of the nickel-based alloy forging side connector 2. The elastic clamping mechanism 3 includes an annular sleeve 31 and a limiting arc sleeve 32. The annular sleeve 31 is integrally formed and disposed at both ends of the outer surface of the nickel-based alloy forging main pipe 1. A limiting spring 33 is installed inside the annular sleeve 31 by screws. An arc-shaped slider 34 is fixedly connected to the outer end of the limiting spring 33. The arc-shaped slider 34 is slidably connected to the inside of the annular sleeve 31. A clamping arm 35 is fixedly installed on the outer side of the arc-shaped slider 34. An arc-shaped locking pin 36 is fixedly installed on the outer side of the clamping arm 35. The limiting arc sleeves 32 are arranged in a ring at equal intervals and welded to the outer surface of the nickel-based alloy forging side joint 2. The end of the arc-shaped locking pin 36 is inserted into the inside of the limiting arc sleeve 32. At the beginning of installation, the limiting spring 33 can be adjusted to compress the arc-shaped slider 34. The limiting spring 33 contracts and stores potential energy. When the arc-shaped locking pin 36 rotates accordingly with the arc-shaped slider 34, the nickel-based alloy forging side connector 2 and the plug connector 4 are interlocked during installation. At this time, the limiting arc sleeve 32 is located at the arc-shaped locking pin 36. When the pressure on the limiting spring 33 is released, the limiting spring 33 returns to its original position and pushes the arc-shaped slider 34 to rotate in an arc shape along the arc-shaped sleeve direction, causing the arc-shaped locking pin 36 to be inserted into the limiting arc sleeve 32, thus locking and limiting the nickel-based alloy forging side connector 2. When disassembly is required, simply readjust the rotation of the support mechanism 6 to disengage the arc-shaped locking pin 36 from the limiting arc sleeve 32. During the application of this device, the elastic locking mechanism 3 enables the rapid installation and disassembly of the nickel-based alloy forging side connector 2 and the nickel-based alloy forging main pipe 1. Before installing the nickel-based alloy forging side connector 2, first adjust the arc-shaped slider 34 to compress the limiting spring 33 installed inside the annular sleeve 31 by screws. The limiting spring 33 contracts and stores potential energy. At this time, the locking arm 35 fixed on the outside of the arc-shaped slider 34 and the arc-shaped locking pin 36 on the outside of the locking arm 35 will rotate synchronously with the arc-shaped slider 34. Then, interlock the plugs 4 at both ends of the nickel-based alloy forging main pipe 1 with the nickel-based alloy forging side connector 2, so that the limiting arc sleeves 32, which are welded in a ring at equal intervals on the outer surface of the nickel-based alloy forging side connector 2, are aligned with the position of the arc-shaped locking pin 36. Then, release the pressure on the limiting spring 33. The limiting spring 33 returns to its original position and pushes the arc-shaped slider 34 to rotate in an arc along the direction of the annular sleeve 31, thereby causing the arc-shaped locking pin 36 to be inserted into the limiting arc sleeve 32, thus enabling the nickel-based alloy forging side connector 2 to be inserted into the annular sleeve 31. The nickel-based alloy forging side connector 2 is clamped and limited to ensure that it is stably fitted onto the outer surface of the connector 4. When it is necessary to disassemble the nickel-based alloy forging side connector 2, simply readjust the support mechanism 6 to rotate, causing the relevant components to disengage the arc-shaped locking pin 36 from the limiting arc sleeve 32, thus completing the disassembly operation. This connection method, achieved through the elastic clamping mechanism 3, does not rely on traditional flange or threaded connections. It eliminates the need for frequent twisting of bolts or threads during installation and disassembly, simplifying the operation and preventing wear on connecting components caused by repeated operations. Furthermore, the clamping and limiting effect achieved by the elastic potential energy of the limiting spring 33 ensures the stability of the nickel-based alloy forging side connector 2 after installation, reducing the likelihood of loosening during use.This improves the ease of use and reliability of the entire device, ensuring that the external pipe 5 welded to the outside of the nickel-based alloy forging side joint 2 can stably cooperate with the nickel-based alloy forging main pipe 1.

[0016] Combination Figures 1-2 As shown, a sealing gasket 7 is provided between the plug connector 4 and the nickel-based alloy forging side connector 2. The sealing gasket 7 is located at the gap after the nickel-based alloy forging main pipe 1 and the nickel-based alloy forging side connector 2 are fitted and sealed. The sealing gasket 7 is used to provide a preliminary seal. A reinforcing sealing sleeve 8 is fixedly connected to the side of the sealing gasket 7 that is close to each other. The reinforcing sealing sleeve 8 is fitted onto the outer surface of the plug connector 4. A reinforcing sealing inner ring sleeve 9 is fixedly connected to the inner side of the nickel-based alloy forging side connector 2. The reinforcing sealing inner ring sleeve 9 is inserted into the inner side of the plug connector 4. The reinforcing sealing sleeve 8 is used to further strengthen the seal. At the same time, the reinforcing sealing inner ring sleeve 9 is used to internally reinforce and support the connection between the plug connector 4 and the nickel-based alloy forging side connector 2 to ensure that they have high strength after docking.

[0017] In the above-described embodiments of this application, the device, through the provision of a sealing gasket 7, a reinforcing sealing sleeve 8, and a reinforcing sealing inner ring sleeve 9, provides multiple layers of protection for the connection between the plug-in 4 and the nickel-based alloy forging side connector 2, meeting the requirements for sealing and structural stability. When the nickel-based alloy forging side connector 2 is fitted onto the outer surface of the plug-in 4, the sealing gasket 7, located between the two and at the gap between the nickel-based alloy forging main pipe 1 and the nickel-based alloy forging side connector 2 after sealing, will first play its role, providing a preliminary seal for the connection and preventing external impurities from entering or internal media from leaking. Simultaneously, the reinforcing sealing sleeve 8, fixedly connected to the side closest to the sealing gasket 7, will also provide a seal. Located on the outer surface of the connector 4, it further enhances the sealing effect on the basis of the initial sealing, improves the sealing performance of the connection, and reduces the possibility of sealing failure. In addition, the reinforced sealing inner ring 9, which is fixedly connected to the inner side of the nickel-based alloy forging side connector 2, is inserted into the inner side of the connector 4 when the two are connected. It not only enhances the overall sealing performance in conjunction with the sealing structure, but also provides internal reinforcement and support for the connection between the connector 4 and the nickel-based alloy forging side connector 2. This ensures that the two have high strength after connection, and avoids problems such as deformation or loosening of the connection due to external force or medium pressure during use. It ensures that the connector 4 and the nickel-based alloy forging side connector 2 always maintain a stable and reliable connection state, and ensures the normal operation of the entire device. Example 2

[0018] Combination Figures 2-5As shown, the support mechanism 6 includes an outer slip ring 61, which slides on the outer surfaces of two annular sleeve rails 31. The inner side of the outer slip ring 61 is fixedly connected to the outer side of the arc-shaped slider 34. A support sleeve 62 is fixedly installed between the inner sides of the outer slip ring 61. The support sleeve 62 is used to mount the reinforced nickel-based alloy forging main pipe 1 to enhance its overall strength. At the same time, the surface of the support sleeve 62 is relatively rough. When it is necessary to disassemble or install the nickel-based alloy forging side joint 2, the outer sliding block is slowly rotated by adjusting the support sleeve 62 to compress the limiting spring 33, which causes the arc-shaped locking pin 36 to disengage from the limiting arc sleeve 32, thus achieving disassembly and assembly. The support mechanism 6 also includes a support ring rail. 63. The support ring rail 63 is welded to the middle of the outer surface of the support sleeve 62. The support ring rail 63 has an inner sliding ring 64 that can be rotated inside. The bottom of the inner sliding ring 64 is welded and installed with a support slider 65. The bottom of the support slider 65 is welded and installed with a telescopic support leg 66. The support ring rail 63 and the inner sliding ring 64 are used to slide against each other to achieve pre-adjustment of the support direction of the telescopic support leg 66, which facilitates the flexible installation and assembly of the support of this forging. The telescopic support leg 66 includes a main support leg 661, which is fixedly connected to the bottom of the support slider 65. The outer surface of the main support leg 661 is fitted with a support frame 662 that is movably connected. The upper end of one side of the support frame 662 The threaded connection includes a limiting screw 663, the end of which passes through the support sleeve 662. The main support leg 661 and the support sleeve 662 slide together, allowing for flexible adjustment of the length of the telescopic support leg 66, facilitating adaptability to different installation applications. The limiting screw 663 is used to lock and fix the main support leg 661 and the support sleeve 662 after adjustment. Limiting holes 664 are evenly spaced on the outer surface of the main support leg 661, and the end of the limiting screw 663 is inserted into the inner side of the limiting hole 664. The limiting screw 663 is a hand-tightening screw with hexagonal bolt holes on its outer side. A support mounting plate 6 is welded to the bottom of the support sleeve 662. 65. Mounting holes 666 are provided at the four corners of the main support 665. The spacing of the limiting holes 664 on the outer surface of the main support 661 can be flexibly selected according to specific needs. If more precise telescopic adjustment is required, corresponding anti-slip joints can be set or the limiting screw 663 can use a finer thread to achieve more precise spacing adjustment. The limiting hole 664 is just one implementation method, and its spacing can be set according to needs. At the same time, the outer end of the limiting screw 663 can be threaded to place a loose screw for further reinforcement. The hexagonal bolt hole is used to insert a wrench to remove and install. If it cannot be tightened by hand, a wrench can be used for removal and installation.

[0019] The technical solution described in the above-described embodiments of this application, during the application of this device, by setting a support mechanism 6, can assist the elastic clamping mechanism 3 in completing the disassembly and assembly operations, provide support and strength enhancement for the nickel-based alloy forging main pipe 1, and flexibly adapt to different installation scenarios. When installing or disassembling the nickel-based alloy forging side joint 2, because the surface of the support sleeve 62 is relatively rough, the operator can adjust the support sleeve 62 to drive the outer slip ring 61 to rotate. The outer slip ring 61 then drives the arc-shaped slider 34 to compress the limiting spring 33 to contract, causing the arc-shaped locking pin 36 to disengage from the limiting arc sleeve 32 to achieve disassembly and assembly. At the same time, the support sleeve 62, which holds the nickel-based alloy forging main pipe 1, can enhance the overall strength of the main pipe and reduce the possibility of deformation of the main pipe during use. When it is necessary to adjust the support direction, the mutual sliding of the support ring rail 63 and the inner slip ring 64 can drive the support slider 65 and the retractable support leg 66 at the bottom to rotate, pre-adjusting the support direction and facilitating flexible installation and assembly of the forging support. When adjusting the support height When adjusting the length, the main support leg 661 and the support frame 662 slide together, allowing for flexible changes in the length of the telescopic support leg 66 to suit different installation requirements. After the length is adjusted, rotating the limiting screw 663 on one side of the support frame 662 causes the end of the limiting screw 663 to pass through the support frame 662 and insert into the limiting hole 664 on the outer surface of the main support leg 661, thus locking and fixing the main support leg 661 and the support frame 662. For more precise telescopic adjustments, corresponding... The anti-slip joint or the limit screw 663 with a finer thread can be used. The spacing of the limit hole 664 can also be flexibly selected according to specific needs. The outer end of the limit screw 663 can also be threaded to a screw to prevent the thread from loosening for further reinforcement. When the limit screw 663 cannot be tightened by hand, a wrench can be inserted into the hexagonal bolt hole on the outside of the limit screw 663 to assist in disassembly and assembly. Finally, by using the mounting holes 666 at the four corners of the support mounting main board 665, the entire device can be fixed in the required position to ensure stability during use.

[0020] The working principle and advantages of this utility model are as follows: Before using this device, the length of the telescopic support leg 66 in the support mechanism 6 is adjusted. The operator can push the support frame 662 to slide along the main support leg 661 and adjust it to a suitable length according to the space height and support requirements of the installation site. After adjustment, the limiting screw 663 at the upper end of one side of the support frame 662 is rotated so that the end of the limiting screw 663 passes through the support frame 662 and is inserted into the limiting hole 664 on the outer surface of the main support leg 661, thereby realizing the connection between the main support leg 661 and the support frame 661. For the locking and fixing of 2, if more precise length adjustment is required in subsequent installation scenarios, the friction can be increased by using the anti-slip textured joint on the outer surface of the main support leg 661, or the limiting screw 663 with a finer thread can be replaced. At the same time, by rotating the inner slip ring 64, the support slider 65 and the telescopic support leg 66 below can be rotated synchronously, thereby adjusting the support direction of the telescopic support leg 66. Once the support direction is determined, the entire nickel-based alloy forging can be fixed in the designated installation position by using the mounting holes 666 at the four corners of the support mounting main board 665. After adjusting and fixing the support mechanism 6, the installation of the nickel-based alloy forging side joint 2 and the nickel-based alloy forging main pipe 1 begins. First, the sealing gasket 7 is placed on the outside of the plug joints 4 at both ends of the nickel-based alloy forging main pipe 1, and the reinforcing sealing sleeve 8 is fitted onto the outer surface of the plug joint 4. Then, the elastic clamping mechanism 3 is adjusted, and the operator pushes the outer slip ring 61 with external force. When the outer slip ring 61 moves, it will drive the arc-shaped slider 34 to slide inside the annular sleeve 31. The arc-shaped slider 34 squeezes the limit spring 33 installed inside the annular sleeve 31 by screws, causing the limit spring 33 to contract and store potential energy. The clamping arm 35 on the outside of the arc-shaped slider 34 and the arc-shaped clamping pin 36 on the outside of the clamping arm 35 will follow the arc. The slider 34 rotates synchronously, and then the nickel-based alloy forging side connector 2 is sleeved on the outer surface of the plug connector 4. At this time, the limiting arc sleeve 32 on the outer surface of the nickel-based alloy forging side connector 2 will be aligned with the position of the arc-shaped locking pin 36, and the reinforcing sealing inner ring sleeve 9 on the inner side of the nickel-based alloy forging side connector 2 will be inserted into the inner side of the plug connector 4. After the external force on the outer slip ring 61 is released, the limiting spring 33 resets and pushes the arc-shaped slider 34 to rotate in an arc along the annular sleeve 31. The arc-shaped locking pin 36 moves accordingly and is inserted into the limiting arc sleeve 32, completing the clamping and limiting of the nickel-based alloy forging side connector 2. At this time, the support sleeve 62 between the inner sides of the outer slip ring 61 will naturally be sleeved on the outer surface of the nickel-based alloy forging main pipe 1. When this device needs maintenance or replacement of the nickel-based alloy forging side connector 2, the operator only needs to start the disassembly process by rotating the support sleeve 62. When the support sleeve 62 rotates, it will drive the outer slip ring 61 to rotate synchronously. The outer slip ring 61 drives the arc-shaped slider 34 to compress the limit spring 33 and contract. The arc-shaped locking pin 36 moves with the arc-shaped slider 34 and gradually disengages from the inside of the limit arc sleeve 32. At this time, the nickel-based alloy forging side connector 2 can be directly removed from the plug connector 4. If resistance is encountered when operating the limit screw 663 and it cannot be turned by hand, the operator can insert a wrench into the hexagonal bolt hole to assist the operation, so that the disassembly process can be carried out smoothly and avoid delays in maintenance progress due to tool compatibility issues. This technical solution replaces the traditional flange or threaded connection method with a flexible clamping mechanism 3, eliminating the need for frequent tightening of bolts or threads when installing and disassembling the nickel-based alloy forging side connector 2. This avoids problems such as thread wear, corrosion, jamming, or stripping, significantly improving assembly and disassembly efficiency. The multi-layered sealing structure, consisting of a sealing gasket 7, a reinforcing sealing sleeve 8, and a reinforcing sealing inner ring 9, effectively solves the problem of poor sealing performance in traditional valve body forgings. The reinforcing sealing inner ring 9 also provides internal reinforcement and support to the connection area. Finally, the support sleeve 62, fitted onto the outer surface of the nickel-based alloy forging main pipe 1, directly enhances the overall strength of the main pipe and reduces the risk of damage caused by the main pipe itself. The deformation caused by weight or external pressure, combined with the synergistic effect of the telescopic support leg 66, the support ring rail 63, and the inner slip ring 64, provides stable support for the entire forging, preventing the forging from tilting or shaking during use. Even if subjected to slight external impact, it can effectively disperse the impact force and reduce the probability of deformation and bending of the forging. By setting the limiting screw 663 to be hand-tight and opening hexagonal bolt holes, and allowing the spacing of the limiting holes 664 on the outer surface of the main support leg 661 to be flexibly selected, this device can better adapt to different usage scenarios, comprehensively solving the problems of poor stability and low adaptability of existing solutions in the background technology, and ensuring that this device can maintain good performance during long-term use. During the application of this device, the fixed installation of each structure can be selected by bolt installation, welding installation, screw installation or some flexible snap-fit ​​installation. If a detachable design is required, bolt or screw installation can be selected. If a stable installation is required, welding installation can be selected. The specific requirements can be flexibly selected according to the application requirements. During the application of this forging, the limiting spring 33 is made of high-carbon chromium bearing steel or piano wire. Both of these materials have excellent mechanical properties and fatigue resistance. High-carbon chromium bearing steel has a carbon content between 0.95% and 1.10% and 1.30% to 1.65% chromium. After quenching and tempering, its surface hardness can reach HRC60-65, which can effectively resist deformation and wear during long-term expansion and contraction. Piano wire is made by drawing high-purity steel wire and special heat treatment process. It has extremely high tensile strength and elastic limit. Its elastic recovery rate is stable and it is not easy to experience elastic decay in frequent expansion and contraction cycles. Springs made of the above materials can have long-term performance during long-term use. They can also maintain high elasticity and high weather resistance, and can maintain elastic locking ability for a long time.
