Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a ribbed mountain-shaped sealing ring. Background Art

[0002] Flanges are the most traditional pipe connectors. Traditional flanges are prone to leakage and failure due to design and structural problems. In order to solve this problem, the applicant developed the ZY-LOC high-pressure self-tightening flange, which solved the problems of traditional flanges through a redesigned high-pressure self-tightening sealing principle. The technology uses a T-shaped sealing ring structure, and the sealing is completed by the elastic deformation of the T-shaped arm of the T-shaped sealing ring. However, in the actual application of various large-scale pipeline systems, some defects that need to be solved urgently have also appeared, that is, the T-shaped arm of the T-shaped sealing ring is thin, and at high temperatures, the rigidity is insufficient and it is easy to deform.

[0003] Based on the above defects, the applicant conducted further technical research and development and developed a mountain-shaped sealing ring (Chinese patent document CN202010128717.X), which is used in high-temperature scenarios and adopts a new sealing principle. It is a non-elastic deformation seal, relying on the straight line contact between the curved surface of the mountain-shaped sealing ring and the ferrule to form a line seal. However, when assembling the mountain-shaped sealing ring, it is often easy to deviate. Utility Model Content

[0004] The utility model aims to provide a ribbed U-shaped sealing ring to solve the problem that the U-shaped sealing ring is prone to deviation during assembly.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A ribbed mountain-shaped sealing ring includes a sealing ring, the cross-sectional structure of the sealing ring includes a rib located in the middle for positioning during assembly, and arms located on both sides of the rib for sealing; the rib includes a vertical section and an inclined section; the inclined section of the rib is located between the arm and the vertical section of the rib; the intersection of the arm and the end face of the sealing ring away from the rib is an arc surface, which is a sealing arc surface, and forms a line seal after contacting the sealing cone surface on the inner side of the sleeve.

[0007] As a preferred technical solution, the angle between the vertical section and the inclined section is an obtuse angle, and the angle between the inclined section and the arm is also an obtuse angle.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] The ribs of the original mountain-shaped sealing ring developed by the applicant are inclined surface structures, and the forces on both ends of the inclined surface are not necessarily uniform and are easily offset, resulting in inaccurate positioning references during installation.

[0010] In the utility model, the structure of the ribs of the original mountain-shaped sealing ring is improved. Ribs with vertical sides are added, and the positioning reference is changed. When the ferrule is pressed over, the ribs are vertical, and the positioning reference is not easy to deviate, and it is aligned as soon as it is installed. Compared with the structure of the T-shaped sealing ring with vertical ribs, it has better resistance to high-temperature creep and is suitable for use in high-temperature scenes.

[0014] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0015] On the contrary, the present application covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present application as defined by the claims. Further, in order to make the public have a better understanding of the present application, some specific details are described in detail in the detailed description of the present application below. Those skilled in the art can fully understand the present application without the description of these details. Example

[0016] like Figure 1-2 As shown, a ribbed U-shaped sealing ring comprises a sealing ring 1, the cross-sectional structure of the sealing ring comprises a rib located in the middle for positioning during assembly, and arms located on both sides of the rib for sealing.

[0017] This embodiment is an improvement based on the triangular rib structure of the mountain-shaped sealing ring. A rib with a vertical surface is added to the middle of the original mountain-shaped rib.

[0018] Therefore, in this embodiment, the rib includes a vertical section 101 of the rib and an inclined section 102 of the rib; the rib of the vertical section 101 of the rib plays a positioning role and provides a positioning reference that is not easily deviated. The inclined section 102 of the rib is located between the arm and the vertical section 101 of the rib.

[0019] The intersection of the arm and the end face of the sealing ring 1 away from the rib is an arc surface, which is a sealing arc surface, and forms a line seal after contacting the sealing cone surface 202 inside the sleeve 3. Specifically, the end face of the sealing ring 1 away from the rib has a certain thickness, and this structure makes the sealing ring 1 more resistant to creep at high temperatures.

[0020] The reason for designing triangular ribs in the chevron seal is that when the arm is thicker, if the angle between the rib and the arm is about 90°, cracks often occur at the junction. In order to resist high temperature creep, the arms of the chevron seal ring are designed to be thicker. In order to solve the cracking problem, triangular ribs are designed.

[0021] In this embodiment, the vertical section 101 of the rib is used for positioning to provide a positioning reference that is not easily deviated; the inclined section 102 of the rib is used as a transition between the vertical section 101 of the rib and the arm. The angle between the vertical section 101 of the rib and the inclined section 102 of the rib is an obtuse angle, and the angle between the inclined section 102 of the rib and the arm is also an obtuse angle. On the basis of keeping the positioning reference not easily deviated, the problem of easy cracking is solved.

[0022] like Figure 2 As shown, when assembling the sealing ring, two sleeves 3 are clamped on both sides of the ribbed mountain-shaped sealing ring. The positioning surface 201 of the sleeve 3 is a vertical surface. When it is close to the rib, the two vertical surfaces match, the rib is evenly stressed and not easily offset. The two clamping sleeves 2 clamp the upper and lower parts of the sleeve 3 and are fastened with bolts and ball nuts. The sleeve 3 and the pipeline form a strong whole, and the bolts and ball nuts fix the two clamping sleeves 2 into a whole.

[0023] It is worth noting that, based on the above structural design, in order to solve the same technical problem, even if some insubstantial improvements are made on the present invention, they also fall within the protection scope of the present invention.
