Description

Technical Field

[0001] This utility model relates to the field of sealing technology for pipelines, specifically a sealing component for a gas pipeline. Background Technology

[0002] In current gas transmission systems, the sealing performance of pipeline connections is crucial to ensuring the safe operation of the entire system. Traditionally, gas transmission pipeline connections primarily rely on flanges and O-rings to achieve a sealing effect. While this connection method can meet basic sealing requirements to a certain extent, some shortcomings have gradually become apparent in long-term practical applications.

[0003] First, as a key component connecting pipelines, flanges are often directly exposed to the natural environment. Since gas pipelines are frequently laid outdoors, flanges are constantly subjected to wind, sun, rain, and temperature fluctuations, making them highly susceptible to rust and corrosion. This not only affects the mechanical strength and connection stability of the flange but also allows impurities from corrosion to enter the sealing surface, further reducing sealing performance.

[0004] Secondly, as another key sealing element, O-rings can provide effective sealing in the short term, but in the long term, due to factors such as pressure fluctuations and temperature changes of the gas medium, as well as the aging of the O-ring material itself, their elasticity and sealing performance will gradually decrease, thereby increasing the risk of gas leakage. Utility Model Content

[0005] (I) Purpose of the utility model

[0006] In view of this, the purpose of this utility model is to provide a sealing component for a gas transmission pipeline, which solves the problems mentioned in the background above.

[0007] (II) Technical Solution

[0008] A sealing assembly for a gas transmission pipeline includes a first pipeline and a second pipeline. A second flange and a first flange are fixedly installed at one end of the first pipeline and the second pipeline, respectively. A movable ring is movably installed on the outer surface of both the first pipeline and the second pipeline. A first sealing cover and a second sealing cover are respectively connected to one end of the movable ring. A magnetic locking ring is connected to one end of the second sealing cover. A clamping ring is connected to one end of the movable ring. The outer surface of the clamping ring is threaded. Multiple sets of vertical through grooves are formed on the outer surface of the clamping ring. A compression ring is movably installed on the outer surface of the clamping ring. The outer surface of the clamping ring is covered with rubber.

[0009] Preferably, one end of the extrusion ring is conical, and multiple sets of operating levers are fixedly installed on the outer surface of the extrusion ring.

[0010] Preferably, limit rings are fixedly installed on the outer surfaces of both the first and second pipes.

[0011] Preferably, a sealing ring is fixedly installed on one side of the second flange, and the outer surface of the sealing ring is wrapped with rubber.

[0012] Preferably, the inner wall of the first pipe is connected to a first protruding ring, and one end of the first protruding ring is connected to a second protruding ring. The outer surfaces of both the first and second protruding rings are covered with rubber.

[0013] Preferably, a first abutment ring is installed on the inner wall of the second pipe, and one end of the first abutment ring is connected to a second abutment ring.

[0014] Preferably, a sealing groove is formed on one outer surface of the first flange.

[0015] As can be seen from the above technical solutions, this application has the following beneficial effects:

[0016] 1. This utility model's connection structure employs innovative designs such as a movable ring, a magnetic snap-fit ​​ring, and a compression ring, enhancing sealing performance. The sliding movable ring ensures a tight fit between the two sealing covers, while the magnetic snap-fit ​​ring's magnetic attraction guarantees a secure seal, forming a protective sealing structure. This not only improves the sealing performance of the pipe connection but also provides an additional protective layer for the flanges and bolts, extending their service life.

[0017] 2. This utility model achieves initial mechanical fixation by precisely connecting the first and second pipes and securing them with flanges and bolts. Simultaneously, the sealing ring is precisely embedded in the sealing groove, forming the first layer of sealing structure, effectively preventing fluid leakage. Furthermore, the tight fit between the protruding ring and the mating ring, along with the rubber layer covering their outer surfaces, further enhances the sealing between the pipes, forming the second layer of sealing structure. This multi-layer sealing design not only improves the stability and safety of the connection but also ensures the efficient operation of the pipeline system, reducing resource waste and environmental pollution caused by leakage.

[0024] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0025] Please see Figure 1-5 One embodiment provided by this utility model:

[0026] A sealing assembly for a gas transmission pipeline includes a first pipeline 1 and a second pipeline 2. A second flange 814 and a first flange 911 are fixedly installed at one end of the first pipeline 1 and the second pipeline 2, respectively. A movable ring 4 is movably installed on the outer surface of both the first pipeline 1 and the second pipeline 2. A first sealing cover 5 and a second sealing cover 6 are connected to one end of the movable ring 4, and a magnetic clamping ring 7 is connected to one end of the second sealing cover 6. A clamping ring 411 is connected to one end of the movable ring 4, and the outer surface of the clamping ring 411 is threaded. Multiple sets of vertical through grooves 412 are formed on the outer surface of the clamping ring 411, and a compression ring 8 is movably installed on the outer surface of the clamping ring 411. The outer surface of the clamping ring 411 is covered with rubber.

[0027] Furthermore, one end of the compression ring 8 is conical, and multiple sets of operating levers 9 are fixedly installed on the outer surface of the compression ring 8. The conical design of the compression ring 8 helps to gradually compress and tightly fit during the connection process, improving the sealing and stability of the connection. The operating levers 8 facilitate manual operation by the user, making the connection process more convenient, and also facilitating disassembly and maintenance.

[0028] Furthermore, limit rings 3 are fixedly installed on the outer surfaces of both the first pipe 1 and the second pipe 2. The setting of the limit rings 3 can effectively limit the displacement of the movable ring 4 and prevent the movable ring 4 from falling off or loosening due to external forces during use.

[0029] Furthermore, a sealing ring 813 is fixedly installed on one side of the second flange 814, and the outer surface of the sealing ring 813 is wrapped with rubber. The design of the rubber sealing ring 813 can provide a good sealing effect and prevent fluid from leaking from the connection.

[0030] Furthermore, the inner wall of the first pipe 1 is connected to a first protruding ring 811, and one end of the first protruding ring 811 is connected to a second protruding ring 812. The outer surfaces of the first protruding ring 811 and the second protruding ring 812 are both covered with rubber. The design of the protruding ring can increase the contact area between the inner wall of the pipe and the connecting parts, and improve the stability and sealing of the connection.

[0031] Furthermore, a first abutting ring 913 is installed on the inner wall of the second pipe 2, and a second abutting ring 914 is connected to one end of the first abutting ring 913. The abutting ring and the protruding ring cooperate with each other, and they abut against each other to compress the rubber, thereby forming a replaceable seal.

[0032] Furthermore, a sealing groove 912 is provided on one side of the outer surface of the first flange 911. The sealing groove 912 is designed to accommodate sealing material, which then fits into the sealing ring 813 to form a seal.

[0033] Working Principle: First, the first pipe 1 and the second pipe 2 are precisely connected. During this process, the first flange 911 and the second flange 814 are fastened together with bolts, forming a preliminary mechanical fixation. At this time, the sealing ring 813 on one side of the second flange 814 will precisely embed into the sealing groove 912 opened on the outer surface of the first flange 911, forming the first sealing structure. Simultaneously, the first protruding ring 811 and the second protruding ring 812 on the inner wall of the first pipe 1 will tightly abut against one end of the first abutting ring 913 and the second abutting ring 914 on the inner wall of the second pipe 2. Since the outer surfaces of these protruding rings and abutting rings are covered with rubber, their tight contact will further compress the rubber, thereby enhancing the sealing between the first pipe 1 and the second pipe 2, forming the second sealing structure.

[0034] Next, by sliding the movable ring 4, the first sealing cover 5 and the second sealing cover 6 gradually approach each other and eventually abut together. At this time, the magnetic locking ring 7 uses its magnetism to hold the first sealing cover 5 in place, ensuring a tight fit between the two sealing covers and forming a third sealing structure. This sealing structure not only enhances the sealing performance of the pipe connection but also provides an additional protective layer to prevent the external environment from affecting the inside of the pipe.

[0035] Finally, by rotating the operating lever 9, the compression ring 8 is driven to gradually install itself into place along the outer surface of the clamping ring 411. Since one end of the compression ring 8 is conical, it gradually compresses the clamping ring 411 as it rotates. The outer surface of the clamping ring 411 has multiple sets of vertical through grooves 412. These grooves allow the clamping ring to gradually contract and tightly fit against the outer surface of the movable ring 4 when compressed. This contraction not only fixes the movable ring 4, preventing it from loosening or falling off, but also further improves the sealing performance of the entire sealing assembly by increasing the compression force on the movable ring 4. Simultaneously, since the outer surface of the clamping ring 411 is also covered with rubber, this compression makes the rubber fit even more tightly between the pipe and the movable ring 4, thereby further enhancing the sealing effect.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
