Technical Field

[0001] This utility model relates to the technical field of flange connection components, and in particular to a flange connection component that is easy to install. Background Technology

[0002] According to Chinese Patent No. CN219345793U, which belongs to the field of flange technology, an easily connectable flange assembly is disclosed, including a first body and a second body. The first body is internally connected with a fastening bolt, and the second body is fixedly connected with a fixing nut. The first body is fixedly connected with a connection limiting mechanism, and the second body has a fixing limiting groove on its outer surface. Through the connection limiting mechanism, the fixing limiting groove, and the connection handle, the first body can be moved as a whole by the connection handle, so that the first body and the second body fit together. Then, through the cooperation between the connection limiting mechanism and the fixing limiting groove, the connection between the first body and the second body can be restricted, so that the positions of the first body and the second body can be aligned, which facilitates the installation of the first body and the second body.

[0003] The aforementioned prior art and related documents have the following technical problems:

[0004] 1. Traditional flange connection assemblies are also inconvenient to disassemble, requiring each bolt to be unscrewed, which increases the workload of maintenance and repair. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flange connection assembly that is easy to install.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a flange connection assembly that is easy to install, comprising a first flange, a connecting bolt on one side of the first flange, a second tubular interface on the outer side of the first flange, a second flange on one side of the connecting bolt, a first tubular interface on the outer surface of the second flange, and a connection port on one side of the first flange.

[0007] Preferably, an elastic gasket is provided on one side of the first flange, and the elastic gasket is fitted to the first flange, with the bottom of the elastic gasket rounded.

[0008] Preferably, one end of the connecting bolt is provided with a nut, and the nut is threadedly connected to one end of the connecting bolt.

[0009] Preferably, the inner surface of the connecting bolt is provided with a sealing ring, and one side of the sealing ring is rounded.

[0010] Preferably, the inner wall of the first flange is provided with a limiting block, and the limiting blocks are arranged in a matrix and the limiting blocks are connected by positioning.

[0011] Preferably, a positioning sleeve is provided on one side of the limiting block, and the positioning sleeve and the limiting block are welded together.

[0012] Preferably, the outer surface of the positioning sleeve is provided with connecting threads, and the connecting threads are welded to the outer surface of the positioning sleeve.

[0013] Beneficial effects

[0014] In this invention, a positioning sleeve is provided on one side of the limiting block. The connecting thread on the surface of the positioning sleeve engages with the center of the second flange, and the first flange also engages with the second flange. This allows for a quick initial connection of the two flanges, and the positioning sleeve provides rapid positioning for the connection. During installation, simply engaging the positioning sleeve with the center of the second flange determines the relative position of the two flanges, significantly reducing alignment and centering time and improving installation efficiency. When further installing bolts and other fastening components, it effectively prevents flange misalignment or movement, making subsequent installation smoother. During pipeline system operation, it can better withstand external forces such as pressure and tension, reducing the possibility of flange loosening or leakage due to external forces. This connection method ensures more even stress distribution on the flanges during connection. The positioning sleeve and the engagement structure distribute force evenly on the contact surface of the flanges, avoiding excessive local stress, thereby improving the overall strength and convenience of the flange connection.

[0015] In this invention, a connecting bolt passes through both the first and second flanges, and an elastic washer also passes through the bolt. A nut is located on one side of the connecting bolt. When the nut is tightened, the elastic washer is compressed, generating elastic force, which further enhances the sealing effect. The elastic force generated by the compression of the elastic washer when the nut is tightened allows the sealing surfaces of the two flanges to fit more tightly. Even when the pipeline system undergoes slight deformation due to factors such as temperature changes and pressure fluctuations, the elastic washer can compensate through its own elastic deformation, maintaining a good sealing effect and effectively preventing media leakage. When the nut is tightened, the elastic washer is compressed, applying a certain preload force to the connecting bolt and the flanges.

[0016] In this invention, a sealing ring is provided on the inner surface of the connecting bolt to enhance the sealing performance of the connection. The presence of the sealing ring provides an additional sealing barrier, effectively filling any tiny gaps that may exist between the connecting bolt and the flange, preventing media leakage from these gaps, and significantly improving the sealing performance of the flange connection. This is particularly suitable for pipeline systems with high sealing requirements, such as pipelines transporting flammable, explosive, toxic, harmful, or high-purity media. By placing the sealing ring on the inner surface of the connecting bolt, no additional complex operations are required during installation. The connecting bolt simply passes through the flange normally, without adding excessive installation steps and time, maintaining ease of installation and improving construction efficiency.

During the operation of the pipeline system, it can better withstand external forces such as pressure and tension, reducing the possibility of flange connection loosening or leakage caused by external forces. This connection method makes the flanges more evenly stressed during the connection process. The positioning sleeve 8 and the screw-on structure can evenly distribute the force on the contact surface of the flange, avoiding excessive local stress, thereby improving the overall strength and convenience of the flange connection. The connecting bolt 3 passes through the first flange 1 and the second flange 2, and the connecting bolt 3 also passes through the elastic washer 6. A nut 5 is provided on one side of the connecting bolt 3. When the nut 5 is tightened, the elastic washer 6 is compressed, generating elastic force, which further enhances the sealing effect.

This is especially suitable for pipeline systems with high sealing requirements, such as pipelines transporting flammable, explosive, toxic, harmful, or high-purity media. By placing the sealing ring 10 on the inner surface of the connecting bolt 3, no additional complex operations are required during installation.
