Description
Technical Field
[0001] The utility model relates to the technical field of target material processing, in particular to a degassing pipe and a degassing device. Background Technique
[0002] As an important part of precision device semiconductor materials, target materials are often welded by hot isostatic pressing to ensure the connection strength and reliability. During the welding process of target materials, the target materials need to be placed into the target material sheath, and the target material sheath needs to be evacuated and degassed so that the inside of the target material sheath reaches the vacuum degree that meets the welding standard. Then, the target material sheath is placed into a hot isostatic pressing furnace for hot isostatic pressing welding, and finally the target materials inside the target material sheath are welded.
[0003] During the hot isostatic pressing welding process, if the target material sheath leaks air, expands, or is hollow, it will cause the failure of target material welding. Therefore, the sealing performance of the target material sheath directly affects the success or failure of target material hot isostatic pressing welding. At present, a degassing device is usually used to pump out the air inside the target material sheath to make it meet the welding standard. The degassing device is generally made of metal aluminum material. Therefore, the degassing pipeline and joints of the degassing device are usually made of aluminum material. Since the aluminum joints are easily deformed after repeated disassembly and assembly with the target material sheath, it will cause air leakage at the interface, affecting the degassing effect of the degassing device, and ultimately resulting in the failure of target material welding inside the target material sheath.

[0028] Please refer to Figure 1 - Figure 2 As shown, the present utility model provides a degassing pipe. The joint of the degassing pipe is not easily deformed, and can maintain the continuous sealing performance at the joint connection, thereby ensuring the degassing effect of the degassing device. The degassing pipe includes a degassing pipeline 1, a first joint 2, a connecting pipe 3 and a locking member. The first joint 2 is arranged at one end of the degassing pipeline 1. The connecting pipe 3 is made of a rigid material. One end of the connecting pipe 3 is hermetically connected to the first joint 2, and the other end of the connecting pipe 3 is connected to the target sleeve. The locking member is configured to fasten the connecting pipe 3 and the first joint 2 to maintain the sealing performance between the connecting pipe 3 and the degassing pipeline 1. By connecting the connecting pipe 3 made of a rigid material to the target sleeve, and utilizing the characteristics of high strength and high toughness of the rigid material, it is ensured that the connecting pipe 3 is not easily deformed, and it is guaranteed that after the connection between the connecting pipe 3 and the target sleeve is repeatedly disassembled and assembled, the airtightness and stability of the connection between the connecting pipe 3 and the target sleeve can still be maintained, ensuring the smooth extraction of gas. By providing the locking member to fasten the first joint 2 and the connecting pipe 3, the locking member can maintain the sealing performance between the connecting pipe 3 and the degassing pipeline 1 and prevent gas leakage. It should be noted that the rigid material for making the connecting pipe 3 can be, but is not limited to, stainless steel or copper alloy.
[0029] As Figure 1 shown, in order to improve the sealing performance between the connecting pipe 3 and the degassing pipeline 1, in some embodiments, a second joint 4 is provided at one end of the connecting pipe 3 connected to the first joint 2. The second joint 4 is an annular structure protruding radially from the outer edge of the connecting pipe 3. The first joint 2 is an annular structure protruding radially from the outer edge of the degassing pipeline 1. The first joint 2 is hermetically connected to the second joint 4. By hermetically connecting the annular protruding parts of the first joint 2 and the second joint 4, since the protruding parts of the two can increase the contact area of the sealing connection, a more reliable sealing effect is further provided. Especially in a high-temperature or high-pressure environment, it is beneficial to reduce the risk of gas leakage. At the same time, the protruding parts of the first joint 2 and the second joint 4 can provide a certain supporting force for each other in the radial direction, which can effectively prevent the second joint 4 of the connecting pipe 3 and the first joint 2 of the degassing pipeline 1 from loosening or shifting during use, enhancing the stability of their connection. Further, the first joint 2 and the second joint 4 can both be set as flanges. The flange connection makes the installation and disassembly between pipelines more convenient, and the flange can provide sufficient connection strength and stability, which is suitable for high-strength and high-load pipeline systems. At the same time, as a common pipeline connector, the flange is widely used, easy to obtain, and has a low cost.
[0030] Continuing as Figure 1As shown, in order to maintain the sealing between the connecting pipe 3 and the degassing pipeline 1, in some embodiments, the locking member is a clamp structure 5, and the clamp structure 5 includes two annular hoop bodies 51 and a locking portion 52. One end of the two annular hoop bodies 51 is hinged, and the other end of the two annular hoop bodies 51 is locked by a detachable locking portion 52, so that the two annular hoop bodies 51 are used to clamp the first joint 2 and the second joint 4 to lock the two. The connection between the first joint 2 and the second joint 4 is kept in a tightly fitted state by the clamp structure 5, so that the first joint 2 and the second joint 4 can maintain a continuous and reliable sealing. When the degassing pipe 1 is closed, the first joint 2 and the second joint 4 can be closed. When the interior of the connecting pipe 3 is in a high temperature or high pressure environment, the first joint 2 and the second joint 4 are prevented from loosening or falling off due to excessive temperature or pressure in the pipe; one end of the two annular hoop bodies 51 of the locking member are connected in a hinged manner, so that the annular hoop bodies 51 can be detachably mounted on both ends of the first joint 2 and the second joint 4, and a locking portion 52 is provided at the other end of the two annular hoop bodies 51. The locking portion 52 enables the annular hoop bodies 51 to generate a clamping force on the first joint 2 and the second joint 4, which can effectively prevent the clamp structure 5 from loosening or falling off due to high temperature or high pressure environment or vibration. Specifically, the locking part 52 of the locking member can be a clamping ear provided at one end of the two annular hoop bodies 51 away from the hinge. When the annular hoop body 51 is sleeved on the first joint 2 and the second joint 4, the clamping ears at both ends are opposite to each other, and threaded through holes are provided on the opposite clamping ears. Bolts are passed through the threaded through holes of the two opposite clamping ears and tightened with nuts. When the two opposite clamping ears are clamped, the annular hoop body 51 generates a clamping force on the first joint 2 and the second joint 4, so that the locking member is locked to the first joint 2 and the second joint 4. Further, an annular groove can be provided on the inner wall of the annular hoop body 51, so that the annular groove matches the shape of the protrusions opposite to the first joint 2 and the second joint 4, and the annular groove plays a limiting role on the first joint 2 and the second joint 4, which not only facilitates the alignment and installation of the first joint 2 and the second joint 4, but also further prevents the relative displacement of the first joint 2 and the second joint 4, forming a more solid sealing effect. In other embodiments, the locking member may be a plurality of bolts and a plurality of nuts, and the protrusions opposite to the first joint 2 and the second joint 4 are provided with a plurality of through holes spaced apart along the circumferential direction of the protrusions, and the bolts pass through the through holes and are threadedly connected with the nuts, so that the first joint 2 and the second joint 4 maintain a sealed connection; multi-point fastening of the bolts and nuts provides a higher mechanical strength and can withstand a greater internal high pressure, and the bolts and nuts are evenly distributed around the protrusions of the first joint 2 and the second joint 4, which can provide a more uniform clamping force and further improve the sealing performance.
[0031] In addition, in order to further enhance the sealing performance between the first joint 2 and the second joint 4, a sealing member 6 can be clamped between the first joint 2 and the second joint 4. Through the sealing member 6, the tiny gap between the first joint 2 and the second joint 4 can be filled, which can provide an additional sealing layer and significantly reduce the risk of gas leakage. It should be noted that the sealing member 6 can be, but is not limited to, an O-ring or a breathable gasket, and can be selected according to the specific usage scenario. Exemplarily, the sealing member 6 can be an O-ring.
[0032] As Figure 2 shown, in order to improve the assembly speed between the connecting pipe 3 and the degassing pipe 1, in some embodiments, the second joint 4 is provided with an annular limiting protrusion 7 along its inner edge. The limiting protrusion 7 protrudes along the axial direction of the connecting pipe 3, and the limiting protrusion 7 can be inserted into the first joint 2. The sealing member 6 is sleeved on the limiting protrusion 7, and the first joint 2 and the second joint 4 clamp the sealing member 6; by using the annular limiting protrusion 7, it can be quickly inserted and aligned with the first joint 2, enabling the rapid assembly of the first joint 2 and the second joint 4, reducing the alignment and adjustment time between the two, and making the assembly process more efficient; by sleeving the sealing member 6 on the limiting protrusion 7 and configuring it between the first joint 2 and the second joint 4, the installation steps are simplified, and it can also ensure that the sealing member 6 is in the correct position during the assembly process, thereby providing a reliable sealing effect.
[0033] It should be noted that the connection methods between the first joint 2 and the degassing pipe 1, the second joint 4 and the connecting pipe 3, and the other end of the connecting pipe 3 and the target sleeve can be, but are not limited to, fixed connections or detachable connections, and are not specifically defined herein.
[0034] The present utility model also provides a degassing device, which includes an exhaust valve and the degassing pipe in any of the above embodiments. The other end of the degassing pipe 1 of the degassing pipe is connected to the exhaust valve. By connecting the connecting pipe 3 made of a rigid material to the target sleeve, using the characteristics of high strength and high toughness of the rigid material, it is ensured that the connecting pipe 3 is not easily deformed, and it is guaranteed that after repeated disassembly and assembly of the connection between the connecting pipe 3 and the target sleeve, the airtightness and stability of the connection between the connecting pipe 3 and the target sleeve can still be maintained, and the smooth extraction of gas can be ensured; by setting a locking member to fasten the first joint 2 and the connecting pipe 3, the locking member can maintain the sealing performance between the connecting pipe 3 and the degassing pipe 1 and prevent gas leakage.
[0035] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present utility model. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
