Description

Technical Field

[0001] The invention relates to the technical field of pipeline connection, in particular to a self-anchoring flexible pipeline joint. Background Art

[0002] In the application of large-diameter pipelines, the sealing and stability of pipe joints are crucial. Currently, the pipe joints on the market mainly include welding, flange connection, threaded connection, socket connection, etc. Among them, the socket connection is widely used in water supply, gas and other fields due to its simple installation method and relatively good sealing performance.

[0003] Traditional spigot-and-socket pipe joints usually rely on the mechanical engagement of the spigot and the socket to achieve connection, but in the face of complex geological environments, they are easily misaligned due to geological settlement or external vibration, resulting in sealing failure. In addition, traditional joints require high installation accuracy, and their stability gradually decreases during long-term use. The present invention significantly improves the stability of the joint when dealing with external forces and small displacements through a self-anchoring design.

[0004] In order to deal with the stability problem of pipe joints under external forces, self-anchoring joints have gradually appeared on the market. Such joints increase the connection strength through structural snap-fit ​​or anchoring devices and reduce loosening or detachment caused by external impact. However, existing self-anchoring devices usually use rigid buckles or metal clips. Although they enhance the impact resistance, the anchoring effect is limited when dealing with complex geological conditions or long-term dynamic changes. When the rigid snap-fit ​​system encounters slight deformation or slight displacement of the pipeline, the anchoring function is prone to failure and cannot provide continuous sealing and connection stability. At the same time, these designs usually require complex installation and maintenance processes, which increases the difficulty and cost of construction.

[0005] Therefore, the following problems still exist in the prior art: 1) There is a lack of self-anchored pipe joints that can provide long-term stable connection and sealing under complex geological conditions; 2) The anchoring effect of existing self-anchoring technologies is limited and cannot adapt to the slight dynamic changes of the pipeline; 3) In the actual construction process, the installation is complicated, which increases the construction time and cost. Therefore, there is an urgent need for a pipe joint with simple design, good flexibility and self-anchoring function to maintain efficient sealing and connection performance in complex environments. Summary of the invention

[0006] The purpose of the present invention is to provide a self-resetting buttress device for an above-ground pipeline spanning section, in order to solve the problems in the prior art of easy dislocation of pipeline joints and poor sealing performance under external forces or geological changes.

[0007] To achieve the above-mentioned purpose, the present invention provides a self-anchoring flexible pipe joint, including a socket component and a socket component, the socket component is provided with two grooves, the grooves are embedded with rubber sealing rings, the socket component is an M-shaped structure, and is provided with anchoring teeth, and gaps are provided between the rubber sealing rings. The gaps between the anchoring teeth and the rubber sealing rings are arranged correspondingly, so that the socket component cooperates with the socket component to achieve self-anchoring connection and sealing.

[0008] Preferably, the rubber sealing ring is made of a highly elastic material and can be adjusted with the deformation of the pipeline when external forces act or geological conditions change, so that the joint has good flexibility and can adapt to deformation.

[0009] Preferably, the pipes on both sides of the groove are designed with inclined surfaces, and both ends of the M-shaped structure of the socket component are also designed with inclined surfaces. The inclined surface design can provide a small longitudinal swing angle when the pipe is subjected to uneven settlement or external force, thereby adapting to the longitudinal displacement of the pipe joint.

[0010] Preferably, the rubber sealing ring arranged in the groove is higher than the edge of the groove, so that the inclined surface of the socket component can produce an appropriate compression ratio when compressing the rubber ring, thereby further enhancing the sealing effect.

[0011] Preferably, there is a contact surface resistance between the socket component and the socket component. When the swing angle of the interface reaches the limit deflection, the contact surface resistance between the socket component and the socket component can prevent the joint from bending and disengaging, and at the same time transmit the bending force to the next section of the pipe to adapt to changes in settlement or displacement.

[0012] The present invention adopts a self-anchoring flexible pipe joint of the above structure, which has the following beneficial effects: (1) It improves the sealing, stability and seismic performance of pipeline joints, and is particularly suitable for large-diameter and long-distance oil and gas transmission, water supply and drainage systems; (2) It can adapt to small lateral displacements and longitudinal swing angles in complex geological environments, ensuring long-term stability and sealing under the influence of external factors such as settlement and earthquake.

[0015] In order to make the purpose, technical scheme and advantages disclosed in the embodiments of the present invention clearer, the embodiments of the present invention are further described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of the present invention and are not intended to limit the embodiments of the present invention. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions.

[0016] like Figure 1-Figure 2 As shown, a self-anchoring flexible pipe joint according to an embodiment of the present invention includes a socket component 1 (left side) and a socket component 4 (right side). Two grooves are designed under the socket component 1, and a rubber sealing ring 2 is embedded in the groove. During installation, the socket end of the pipe is inserted into the socket end, and the rubber sealing ring 2 is sealed by compression to prevent leakage of the medium. The M-shaped socket component 4 has a unique design structure and is provided with anchor teeth 3. A gap is provided between the rubber sealing ring 2. The gap between the anchor teeth 3 and the rubber sealing ring 2 is correspondingly arranged, which can achieve structural interlocking with the socket component 1 and maintain a tight connection under the action of external force.

[0017] The rubber seal ring 2 is made of highly elastic material, has excellent elasticity and deformation recovery ability, can effectively adapt to the slight displacement or deformation of the pipeline, and ensure the sealing performance. When the pipelines are connected, the rubber seal ring 2 forms a reliable seal through compression to prevent liquid or gas leakage. The design of the M-shaped socket component 4 can disperse the external force at the pipeline joint, thereby enhancing the stability of the connection and preventing dislocation or loosening under pressure, vibration or deformation conditions. Especially under complex geological conditions such as earthquakes and settlements, the reliability of pipeline connections can be significantly improved.

[0018] Both ends of the M-shaped structure of the socket component 4 are inclined, and the pipe walls on both sides of the groove of the plug component 1 are also inclined. When the pipeline is subjected to uneven settlement or external force, it can provide a small longitudinal swing angle to adapt to the longitudinal displacement of the pipeline joint.

[0019] The rubber sealing ring 2 arranged in the double grooves of the socket component 1 is higher than the edge of the groove, so that the inclined surface of the socket produces a proper compression ratio when compressing the rubber ring, thereby further enhancing the sealing effect.

[0020] When the swing angle of the interface reaches the limit deflection, the contact surface resistance between the socket part 1 and the socket part 4 can prevent the joint from bending and disengaging, while transmitting the bending force to the next joint of the pipeline to adapt to changes in settlement or displacement.

[0021] Therefore, the present invention adopts the above-mentioned self-anchoring flexible pipe joint, which is suitable for complex geological conditions such as earthquakes and geological subsidence. The self-anchoring connection is achieved through the M-shaped joint and the rubber sealing ring, which not only improves the sealing performance, but also simplifies the installation steps. It can produce tiny lateral displacement and longitudinal swing angle in complex geological environments, ensuring long-term stability and sealing under the influence of external factors such as subsidence and earthquakes.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
