Description

Technical Field

[0001] This utility model relates to the field of sealing ring connection technology, and in particular to a sealing connection structure for a sealing ring forging. Background Technology

[0002] Forged sealing rings are ring-shaped components made through forging processes. They are characterized by high strength and high reliability and are widely used in machinery, chemical, aerospace and other fields. Their sealing connection structure refers to a structural design that forms a tight seal between two or more components through specific geometric shapes, material combinations and assembly methods to prevent fluid (gas, liquid) leakage or intrusion of external impurities.

[0003] In pipeline connection scenarios, sealing ring structures are often used to achieve sealing at the pipe joint. Currently, most common pipeline sealing ring connection structures are completed by squeezing the sealing ring between two pipes and cooperating with other structures. However, during long-term use, such structures are prone to loosening due to continuous vibration generated during the transport of media inside the pipe. At the same time, it is difficult to maintain the internal components after installation, which has certain limitations. Based on this, this application proposes a sealing connection structure for a sealing ring forging. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sealing connection structure for a sealing ring forging to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a sealing connection structure for a sealing ring forging, comprising two pipes symmetrically distributed from left to right, a sealing assembly disposed between the two pipes, and a sealing groove provided at the end of each pipe near the sealing assembly. The sealing assembly includes a connecting ring, two sealing rings, a compression ring, and a closing ring. The connecting ring is located between the two pipes, the two sealing rings are symmetrically fitted onto the connecting ring from left to right, and the two sealing rings are respectively fitted into the sealing grooves at the ends of the two pipes, the compression ring is fitted onto the connecting ring and located between the two sealing rings, and the closing ring is fitted onto the outside of the compression ring.

[0006] Furthermore, the axial length of the connecting ring is the same as the distance between the two pipes, and the inner diameter of the connecting ring is the same as the inner diameter of the pipe. The cross-section of the sealing ring is an isosceles trapezoid, and both ends of the outer wall of the connecting ring are provided with outward protrusions. The side walls of the two outward protrusions are set as inclined surfaces that are adapted to the sealing ring, and the shape of the sealing groove is adapted to the shape of the sealing ring.

[0007] Furthermore, when the inner wall of the sealing ring fits against the outer protrusion at the end of the connecting ring, the portion of the sealing ring extending out of the connecting ring is fitted into the sealing groove at the end of the pipe, and the outer wall of the sealing ring fits tightly against the inner wall of the sealing groove.

[0008] Furthermore, both the extrusion ring and the closing ring are divided into two semi-circular rings, and the two semi-circular rings of the extrusion ring are fixedly installed on the inner walls of the two semi-circular rings of the closing ring. Both sides of the extrusion ring are provided with an integral flange. When the extrusion ring is located between the two sealing rings, the inner wall of the flange is tightly fitted with the inclined surface of the outer ring wall of the two sealing rings. The axial length of the inner ring of the extrusion ring is the same as the axial length of the horizontal part of the outer wall of the connecting ring. The axial length of the outer ring of the extrusion ring is the same as the distance between the two pipes. The outer ring diameter of the extrusion ring is the same as the outer ring diameter of the pipe.

[0009] Furthermore, the axial length of the closed ring is greater than the distance between the two pipes, and the inner wall of the closed ring fits against the outer wall of the pipes. The outer walls of the two pipes near the sealing component are provided with annular grooves, and the side of the annular groove near the sealing component is set as an inclined surface. Both ends of the inner wall of the closed ring are provided with flanges that are adapted to the shape of the annular grooves, and the flanges at both ends of the inner wall of the closed ring are respectively fitted into the annular grooves on the outer walls of the two pipes.

[0010] Furthermore, an external hinge is provided at the bottom joint of the two semicircular rings of the closed ring, and a semi-cylindrical screw is fixedly installed at the top of each of the two semicircular rings. A threaded ring is threaded on the two closed joint screws, and a through opening is opened on the outer wall of each screw. Aligned through holes are opened on both sides of the threaded ring, and a bolt is inserted through the through hole and the two through openings.

[0011] The beneficial effects of this utility model are as follows: By fully fitting the sealing ring with the sealing groove at the end of the pipe, the sealing effect of the connection can be improved. The inner bevel of the sealing ring presses against the outer protrusion of the outer wall edge of the connecting ring, so that the connecting ring is precisely aligned between the two pipes. The closed compression ring can compress the two sealing rings, so that the two sealing rings are stably fitted into the sealing grooves at the ends of the two pipes. The flanges on both sides of the compression ring can also compress the outer bevel of the sealing ring. With the cooperation of the closing ring, the closing ring is tightly fitted to the outside of the connection end of the two pipes. The flanges at both ends of the inner wall of the closing ring are just fitted into the annular grooves on the outer walls of the two pipes. Through compression, the two pipes are tightly joined and fitted to both sides of the sealing assembly. Finally, the threaded ring and two screws are used for double locking. This connection structure can fully improve the sealing and stability of the connection through the fitting and compression between the structures. Furthermore, the bevel fitting between the closing ring and the annular groove of the pipe, and the double locking mechanism of the threaded ring and the bolts can effectively absorb vibration energy and prevent the connection from loosening.

[0012] When maintaining the structure in the sealing assembly, simply unscrew the bolts and threaded rings, then separate the closing ring and the compression ring. Without the constraint of the compression ring, the sealing ring can be separated from the sealing groove of the pipe, allowing the two sealing rings to move onto the connecting ring. Then, it can be removed from between the two pipes, thus enabling maintenance or replacement of each structure. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1-7This utility model provides a technical solution: a sealing connection structure for a sealing ring forging, comprising two pipes 1, which are symmetrically distributed from left to right. A sealing assembly is provided between the two pipes 1. A sealing groove 2 is provided at the end of each pipe 1 near the sealing assembly. The sealing assembly includes a connecting ring 4, two sealing rings 5, a compression ring 6, and a closing ring 7. The connecting ring 4 is located between the two pipes 1. The two sealing rings 5 ​​are symmetrically fitted onto the connecting ring 4 and are respectively embedded in the sealing grooves 2 at the ends of the two pipes 1. The compression ring 6 is fitted onto the connecting ring 4 and located between the two sealing rings 5. The closing ring 7 is fitted outside the compression ring 6. By compressing the sealing rings 5 ​​with the compression ring 6, the two sealing rings 5 ​​are respectively embedded in the sealing grooves 2 at the ends of the two pipes 1. Then, the closing ring 7 can be used to connect the two pipes 1 and can fix and restrict the positions of the compression ring 6, the sealing rings 5, and the connecting ring 4.

[0024] like Figure 3 , Figure 4 and Figure 5 As shown, the axial length of the connecting ring 4 is the same as the distance between the two pipes 1, and the inner diameter of the connecting ring 4 is the same as the inner diameter of the pipe 1. The cross-section of the sealing ring 5 is an isosceles trapezoid. Both ends of the outer wall of the connecting ring 4 are provided with outward protrusions 41, and the side walls of the two outward protrusions 41 are set as inclined surfaces adapted to the sealing ring 5. The shape of the sealing groove 2 is adapted to the shape of the sealing ring 5. Through the tight fit between the sealing ring 5 and the sealing groove 2, the sealing effect between the sealing assembly and the pipe 1 can be improved. Furthermore, the inner inclined surface of the sealing ring 5 presses against the outward protrusions 41 on the edge of the outer wall of the connecting ring 4, so that the connecting ring 4 is precisely aligned between the two pipes 1, thereby realizing the connection between the two pipes 1.

[0025] like Figure 3 and Figure 4 As shown, when the inner wall of the sealing ring 5 is fitted with the outer protrusion 41 at the end of the connecting ring 4, the part of the sealing ring 5 extending out of the connecting ring 4 is fitted into the sealing groove 2 at the end of the pipe 1, and the outer wall of the sealing ring 5 is tightly fitted with the inner wall of the sealing groove 2. The outer protrusions 41 on both sides of the connecting ring 4 can limit the range of movement of the sealing ring 5, so that the sealing ring 5 is separated from the connecting ring 4. The tight fit between the outer protrusions 41 and the inclined surface of the inner wall of the sealing ring 5 can improve the sealing effect between the two.

[0026] like Figure 2 and Figure 4As shown, both the compression ring 6 and the closing ring 7 are divided into two semi-circular rings. The two semi-circular rings of the compression ring 6 are fixedly installed on the inner walls of the two semi-circular rings of the closing ring 7. Both sides of the compression ring 6 are provided with an integral flange. When the compression ring 6 is located between the two sealing rings 5, the inner wall of the flange is tightly fitted with the inclined surface of the outer ring wall of the two sealing rings 5. The axial length of the inner ring of the compression ring 6 is the same as the axial length of the horizontal part of the outer wall of the connecting ring 4. The axial length of the outer ring of the compression ring 6 is the same as the distance between the two pipes 1. The outer diameter of the compression ring 6 is the same as the outer diameter of the pipe 1. By fitting the compression ring 6 around the outside of the connecting ring 4, it can compress the two sealing rings 5, so that the two sealing rings 5 ​​are respectively embedded in the sealing grooves 2 at the ends of the two pipes 1, which can play a role in positional constraint on the two sealing rings 5.

[0027] like Figures 2 to 6 As shown, the axial length of the closing ring 7 is greater than the distance between the two pipes 1, and the inner wall of the closing ring 7 fits against the outer wall of the pipe 1. The outer walls of the two pipes 1 near the sealing assembly are provided with annular grooves 3, and the side of the annular grooves 3 near the sealing assembly is set as an inclined surface. Both ends of the inner wall of the closing ring 7 are provided with flanges that are adapted to the shape of the annular grooves 3, and the flanges at both ends of the inner wall of the closing ring 7 are respectively fitted into the annular grooves 3 on the outer walls of the two pipes 1. After the closing ring 7 is fitted onto the joint end of the two pipes 1, the flanges on both sides of the inner wall of the closing ring 7 are fitted into the annular grooves 3, and the two pipes 1 are tightly pressed against the sides of the sealing assembly by the flanges, which can improve the sealing effect of the connection between the two pipes 1. It can also stably fit the closing ring 7 and the compression ring 6 between the joint end of the two pipes 1. The stable compression of the compression ring 6 can ensure that the two sealing rings 5 ​​are tightly fitted into the sealing grooves 2 at the ends of the two pipes 1. Through the fitting and compression between the structures, the sealing performance of the pipe 1 connection can be greatly improved.

[0028] like Figure 1 and Figure 2 As shown, an external hinge 8 is provided at the bottom joint of the two semicircular rings of the closed ring 7. A semi-cylindrical screw 9 is fixedly installed on the top of each of the two semicircular rings. A threaded ring 11 is threaded onto the two closed joint screws 9. A through-hole 10 is opened on the outer wall of each of the two screws 9. Aligned through holes 12 are opened on both sides of the threaded ring 11. A bolt 13 is inserted between the through hole 12 and the two through-holes 10. The two semicircular rings of the closed ring 7 are connected by the external hinge 8. The threaded ring 11 can be used to lock the two closed screws 9. The position of the threaded ring 11 is fixed on the two screws 9 by the bolt 13, so that the threaded ring 11 cannot be detached from the screws 9. This allows the closed ring 7 and the compression ring 6 to be stably fitted at the joint of the pipe 1.

[0029] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
