Technical Field

[0001] The utility model provides a corrosion-resistant copper shell, belongs to the technical field of copper protection shells, and particularly relates to a protection shell for pipelines. Background Art

[0002] A pipeline is a structure used to transport fluids. They are widely used in the fields of industry, construction, agriculture, energy, chemical industry, water conservancy, etc., and are used to transport various media, including water, oil, natural gas, etc. Pipeline systems are usually composed of pipes, pipe fittings, valves, brackets and connectors, and can be constructed into pipe networks of various forms and sizes. The use environment of pipelines is relatively complex, and it is inevitable that there will be some pipelines used in highly corrosive environments. For such pipelines, a protective shell is usually set; the copper shell has stronger corrosion resistance than general metals or other materials, mainly because copper will form a dense oxide layer on its surface, which can prevent further oxidation reactions.

[0003] For the same pipeline, the length in a highly corrosive environment is often different. According to the different lengths of the pipelines that need to be protected, copper protective shells of different lengths are often required. However, the length of existing copper shells is often fixed after production, which makes it inconvenient to adjust the protection length range; and the stability of the connection between the pipeline and the shell is insufficient, which can easily affect the sealing of the shell and the pipeline protection. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the length of the copper shell for pipeline corrosion protection is inconvenient to adjust and is not suitable for pipelines with different protection lengths. At the same time, the connection stability between the pipeline and the shell is insufficient, which affects the sealing performance.

[0006] As an improvement, a retaining ring fixedly sleeved on the fixing rod is arranged in the fixing cylinder, and a compression spring sleeved on the fixing rod is arranged in the fixing cylinder.

[0007] As an improvement, the retaining ring is located in the fixing tube near the fixing hole, and the compression spring has a reserved compression amount.

[0008] As an improvement, a lifting plate located in the clamping cylinder is threadedly connected to the screw rod, and a connecting rod fixedly connected to the clamping plate is fixedly connected below the lifting plate; the connecting rod is slidably arranged relative to the extension shell.

[0009] As an improvement, a rubber pad is provided on the inner side of the clamping plate, and sealing rings are provided at the position where the tube body is connected to the barrel shell, the position where the tube body is connected to the extension shell, and the position where the copper shell is connected to the extension shell.

[0019] The utility model is further described below in conjunction with the accompanying drawings.

[0020] according to Figure 1-5As shown: the utility model provides a corrosion-resistant copper shell: comprising a tube body 1, a copper shell 2 is sleeved on the tube body 1; a slide groove 8 is opened in the copper shell 2, an extension shell 4 is slidably arranged in the slide groove 8, and the extension shell 4 is provided with fixing holes 3 evenly distributed at equal distances; a fixing cylinder 6 is fixedly arranged on the copper shell 2, and a fixing rod 7 inserted into the fixing hole 3 is arranged in the fixing cylinder 6; a clamping cylinder 10 is fixedly connected to one end of the extension shell 4, and a screw 11 is rotatably arranged in the clamping cylinder 10; two clamping plates 9 corresponding to the tube body 1 are arranged in the extension shell 4.

[0021] An extended shell 4 is provided to change the length of the entire copper shell 2, thereby being suitable for tube bodies 1 that require different protection lengths; at the same time, a screw 11 is provided to drive the clamping plate 9 to clamp the tube body 1, thereby increasing the stability of the connection between the tube body 1 and the copper shell 2, and preventing the mutual movement between the two from affecting the sealing of the copper shell 2 to the tube body 1.

[0022] A retaining ring 14 fixedly sleeved on the fixing rod 7 is arranged in the fixing cylinder 6, and a compression spring 15 sleeved on the fixing rod 7 is arranged in the fixing cylinder 6. The retaining ring 14 is located in the fixing cylinder 6 near the fixing hole 3, and the compression spring 15 has a reserved compression amount.

[0023] The compression spring 15 has a reserved compression amount that can continuously generate pressure on the retaining ring 14 , thereby increasing the stability of the fixing rod 7 for the extension housing 4 .

[0024] A lifting plate 12 located in the clamping cylinder 10 is threadedly connected to the screw rod 11 , and a connecting rod 13 fixedly connected to the clamping plate 9 is fixedly connected below the lifting plate 12 ; the connecting rod 13 is slidably arranged relative to the extension shell 4 .

[0025] The setting of the connecting rod 13 can limit the rotation of the lifting plate 12 , thereby converting the rotation of the screw rod 11 into the movement of the lifting plate 12 , and transmitting the movement to the clamping plate 9 through the connecting rod 13 .

[0026] A rubber pad is arranged inside the clamping plate 9 , and sealing rings 5 ​​are arranged at the position where the tube body 1 is connected to the cylinder shell, the position where the tube body 1 is connected to the extension shell 4 , and the position where the copper shell 2 is connected to the extension shell 4 .

At the same time, the setting of the sealing ring 5 can increase the sealing between the tube body 1, the copper shell 2, and the extension shell 4, preventing external corrosive substances from entering the copper shell 2 through the gap to corrode the tube body 1.

[0028] Principle of the utility model

[0029] Before using the copper shell 2, the length of the copper shell 2 needs to be adjusted according to the length of the tube body 1 to be protected; Figure 5 As shown, the fixing rod 7 is pulled outward to disengage the fixing rod 7 from the fixing hole 3, and at the same time, the retaining ring 14 compresses the compression spring 15; the extension shell 4 is pulled to slide in the slide groove 8 to change the length of the extension shell 4 extending from the copper shell 2 itself; a suitable fixing hole 3 is selected, and the fixing rod 7 is loosened. Under the action of the rebound force of the compression spring 15, the fixing rod 7 is inserted into the fixing hole 3, thereby fixing the extension shell 4, which can realize the adjustment of the protection length and is convenient to adjust.

[0030] like Figure 3-4 As shown, after the copper shell 2 and the extension shell 4 are sleeved on the tube body 1, the screw 11 is screwed to make the two clamping plates 9 approach each other under the drive of the lifting plate 12, so that the tube body 1 is fixed by the clamping plates 9, the connection stability of the tube body 1 and the copper shell 2 is increased, and the possibility of relative sliding between the tube body 1 and the copper shell 2 is reduced, thereby increasing the sealing stability of the tube body 1 and the copper shell 2; finally, the sealing ring 5 is used to seal the connection positions of the tube body 1, the copper shell 2, and the extension shell 4 in sequence, as shown in FIG. Figure 1-2 shown.

[0031] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
