DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0031] Embodiment 1:

[0032] See also Figure 1 and Figure 2 The utility model provides a carbon fiber high-performance composite elbow, comprising an elbow body 1, wherein both ends of the elbow body 1 are respectively connected with movable sockets 2, and the sockets 2 are connected to the elbow body 1.

[0033] For details, see Figure 2 and Figure 3An internal thread 3 is provided on the inner wall of the elbow body 1, an extension tube 4 is connected to the connecting end of the socket 2 with the elbow body 1, an adjustment disk 5 is connected to the end of the extension tube 4, the extension tube 4 and the adjustment disk 5 are located in the elbow body 1, an adjustment sealing ring 6 is fixedly installed on the outer side of the adjustment disk 5, an external thread is provided on the outer wall of the adjustment sealing ring 6, and the external thread on the adjustment sealing ring 6 is sealed and connected with the internal thread 3 provided on the inner wall of the elbow body 1.

[0034] The end of the elbow body 1 is provided with a limit edge 10, and the outer diameter of the adjustment disk 5 is larger than the inner diameter of the limit edge 10. Such a setting ensures that the socket head 2 will not move out of the elbow body 1 when it moves. The outer diameter of the adjustable sealing ring 6 can also be set to be larger than the inner diameter of the limit edge 10, which can also ensure that the socket head 2 will not move out of the elbow body 1 when it moves.

[0035] When in use, according to the laying conditions of the elbow body 1 and the corresponding connecting pipe, the socket 2 used to connect the pipe is extended and rotated. Specifically, one end of the connecting pipe can be connected to the socket 2, and the connection method can be threaded connection and adhesive connection, which is not specifically limited;

[0036] According to the laying conditions of the connecting pipeline, by rotating the socket joint 2, one end of the socket joint 2 drives the extension pipe 4 to rotate, and the extension pipe 4 drives the adjustment disk 5 to rotate, so that the adjustment sealing ring 6 outside the adjustment disk 5 rotates, and the adjustment sealing ring 6 is threadedly rotated inside the elbow body 1 through the external thread and the internal thread 3, so that the socket joint 2 can be rotated or extended, thereby realizing the effect of rotation angle adjustment or extension adjustment according to the laying conditions of the pipeline, which is convenient for operators to use.

[0037] See also Figure 4 and Figure 5 , the elbow body 1 includes a conductive layer 101 located on the inner side and a structural layer 103 located on the outer side, and an anti-seepage layer 102 is arranged between the conductive layer 101 and the structural layer 103. Specifically, the conductive layer 101 is made of carbon fiber felt and glue, which can improve the conductivity and enhance the strength of the elbow body 1. The anti-seepage layer 102 is made of epoxy fiber felt and resin, which greatly improves the corrosion resistance and sealing of the elbow body 1. The structural layer 103 is made of carbon fiber bundles and resin, and the carbon fiber bundles are provided with multiple bundles, each bundle of carbon fiber yarn includes 20 to 30 carbon fiber yarns, and multiple bundles of carbon fiber bundles are spirally arranged on the anti-seepage layer 102. The setting of the carbon fiber bundles improves the conductivity of the elbow body 1, while increasing the strength of the elbow body 1 and improving its applicability. The thickness of the conductive layer 101, the anti-seepage layer 102 and the structural layer 103 changes proportionally (increases or decreases) as required by the thickness design of the elbow body 1.

[0038] When preparing the elbow body 1, carbon fiber felt is directly laid on the mold as the first inner lining layer, and glue is applied on the carbon fiber felt to complete the preparation of the conductive layer 101; then epoxy fiber felt is laid on the outside of the conductive layer 101 as the second inner lining layer, and resin is applied on the epoxy fiber felt to complete the preparation of the anti-seepage layer 102; secondly, multiple bundles of carbon fiber bundles are wrapped around the outside of the conductive layer 101 as the outermost layer; resin is applied on the carbon fiber bundles to complete the preparation of the structural layer 103.

[0039] Embodiment 2:

[0040] See also Figure 6 The utility model also provides a carbon fiber high-performance composite elbow, which is different from the above embodiment in that: the two ends of the elbow body 1 are respectively connected with movable sockets 2. In order to ensure its sealing performance and to make the socket 2 structure more stable and not to fall out of the elbow body 1, a limiting cap 8 with a central opening is provided at the connection between the two ends of the elbow body 1 and the socket 2, and the extension pipe 4 of the socket 2 can pass through the central opening of the limiting cap 8. The limiting cap 8 is an integrally formed structure, including a fixing portion 82 and a brim limiting portion 81. The fixing portion 82 is installed at the port of the elbow body 1 and can be fixed in an existing manner.

[0041] Specifically, the end of the extension tube 4 is connected to an adjusting disk 5, and a limiting disk 9 is arranged on the opposite side of the adjusting disk 5. A limiting sealing ring is fixedly installed on the outer side of the limiting disk 9, and the limiting sealing ring is sealed and connected with an internal thread 3 arranged on the inner wall of the elbow body 1.

[0042] The limit plate 9 is sleeved on the extension tube 4, and at least three retractable springs 7 are arranged between the adjustment plate 5 and the limit plate 9, and the two ends of the spring 7 are respectively fixed on the adjustment plate 5 and the limit plate 9. The limit plate 9 abuts against the brim limit portion 81 when the socket 2 rotates and extends outward. The sealing connection method of the adjustment plate 5 and the elbow body 1 is the same as that of the above embodiment, so it is not repeated.

[0043] When in use, the rotating socket 2 is adjusted or extended to adapt the pipe connected thereto. During the rotation or extension process, the limiting disk 9 is located in the cavity formed by the elbow body 1 and the limiting cap 8 connected together. When the socket 2 is rotated to extend outward, the adjusting seal ring 6 originally installed on the adjusting disk 5 forms a first-layer sealing relationship with the elbow body 1, and the limiting seal ring forms a second-layer sealing relationship with the elbow body 1, further improving the sealing performance between the socket 2 and the elbow body 1. Due to the limiting effect of the limiting cap 8, the limiting disk 9 abuts against the brim limiting portion 81 when the socket 2 is in the extended state, and the spring 7 is in a compressed state at this time. When the socket 2 is in the compressed state, the limiting disk 9 follows the adjusting disk 5 under the action of the spring 7 to move away from the brim limiting portion 81 or still abuts against the brim limiting portion 81, and the spring 7 is in an extended state.

[0044] Embodiment three:

[0045] The utility model also provides a high-performance carbon fiber composite elbow, which is different from the above embodiment in that: since the crude oil transported by oil fields generally contains sulfur, in order to avoid impact corrosion of the elbow body 1 during oil transportation, the wall thickness of the elbow body 1 is uniquely designed. Figure 7 The elbow body 1 is divided into two parts with the center line in the vertical direction as the boundary, namely, the impact side wall 12 and the buffer side wall 11. The impact side wall 12 is located on the side where the impact force of crude oil transportation is larger during oil transportation, and the buffer side wall 11 is located on the side where the impact force of crude oil transportation is smaller during oil transportation. The wall thickness of the impact side wall 12 is greater than that of the buffer side wall 11.

[0046] The utility model provides a carbon fiber high-performance composite elbow. By arranging an adjustable extension bearing joint, the rotation angle and the extension length can be adjusted according to the laying conditions of the pipeline, which is convenient for operators to use and improves the scope of use. By arranging a conductive layer, an anti-seepage layer and a structural layer, the conductivity of the elbow body is improved, and the corrosion resistance and sealing of the elbow body are improved, thereby improving the overall use effect and service life of the elbow.

[0047] Of course, the present invention may have many other embodiments.
