Description

Technical Field

[0001] This utility model relates to the field of compensator technology, specifically a thermal pipeline compensator. Background Technology

[0002] Pipeline compensators, also known as expansion joints or expansion joints, are mainly used to compensate for the thermal expansion and contraction of pipelines caused by temperature changes. If the pipeline cannot expand or contract freely when the temperature changes, thermal stress will be generated in the pipeline. This stress must be considered in pipeline design, otherwise it may lead to pipeline rupture and affect normal production.

[0003] The thermal pipeline compensator disclosed in the authorization announcement number CN 217843114 U effectively solves the problems of inconvenient installation and disassembly and insufficient expansion and contraction effect of the current thermal pipeline compensator, and achieves the purpose of convenient installation and disassembly and better expansion and contraction effect. It is a very practical thermal pipeline compensator. However, it does not solve the problem that the limiting components of the existing device are prone to wear, resulting in a reduced service life, and that the weld joint cannot be covered, leading to rainwater erosion. Therefore, we propose a thermal pipeline compensator. Utility Model Content

[0004] The purpose of this invention is to provide a thermal pipeline compensator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A thermal pipeline compensator includes a compensator, an assembly mechanism fixedly installed on the inner side of the compensator, the assembly mechanism including a flange, an assembly column and a compression spring, flanges fixedly installed at both ends of the compensator, a plurality of assembly columns fixedly installed on the inner side of the flanges, a compression spring fixedly installed on one side of the inner side of the assembly column, a piston plate fixedly installed on one side of the compression spring, a tension spring fixedly installed at one end of the piston plate, a connecting rod fixedly installed inside the tension spring, one end of the connecting rod fixedly connected to the piston plate, and a covering mechanism fixedly installed at one end of the flange.

[0007] Preferably, the covering mechanism includes a welded pipe, an assembly plate, and threaded grooves. A welded pipe is fixedly installed on one side of the compensator, and an assembly plate is fixedly installed on the outer side of the welded pipe. The assembly plate has several threaded grooves inside, and a splicing plate is movably installed on one side of the assembly plate. A covering pipe is fixedly installed at one end of the splicing plate, and a rubber layer is fixedly installed on the inner surface of the covering pipe. Several hexagonal screws are movably installed inside the splicing plate. By installing a welded pipe on one side of the compensator, installing an assembly plate on the outer side of the welded pipe, having several threaded grooves inside the assembly plate, and having a splicing plate movably installed on one side of the assembly plate, and installing a covering pipe at one end of the splicing plate, with a rubber layer installed on the inner surface of the covering pipe and several hexagonal screws movably installed inside the splicing plate, the heat pipe is welded to the welded pipe. Rotating the hexagonal screws fixes the assembly plate and the splicing plate together. The covering pipe can cover the welded part, preventing rainwater penetration and erosion, which could lead to structural damage and require frequent maintenance by repair personnel.

[0008] Preferably, the diameter of the covering tube is longer than the diameter of the welding tube, and the diameter of the covering tube is slightly longer than the diameter of the welding tube, so that it can just cover the welding tube, ensuring that the covering tube can cover rainwater and prevent rainwater from penetrating to the welding point.

[0009] Preferably, the hexagonal screw is movably connected to the threaded groove. By connecting the hexagonal screw to the threaded groove, it is ensured that the hexagonal screw can fix the assembly plate and the splicing plate together.

[0010] Preferably, a waterproof adhesive layer is fixedly provided on one side of the splicing tray. By using glue to fix the waterproof adhesive layer on one side of the splicing tray, it is ensured that rainwater will not enter the interior through the gap between the splicing tray and the assembly tray.

[0011] Preferably, the flange has a handle groove inside, which facilitates the handling of the entire device.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This type of thermal pipeline compensator comprises welding a flange to each end of the compensator, welding four assembly columns to the inner side of each flange, welding a compression spring to one side of the inner side of each assembly column, welding a piston plate to one side of the compression spring, welding a tension spring to the other end of the piston plate, and welding the other end of the tension spring to the inside of the assembly column. A connecting rod is fixedly installed inside the tension spring and welded to the piston plate. During operation, the compensator will expand and contract due to thermal expansion and contraction, causing it to expand and contract unpredictably. The piston plate and connecting rod move inside the assembly column, allowing the assembly mechanism to limit the compensator. The installation of the compression spring and tension spring makes the piston plate move more smoothly inside the assembly column, reducing the friction of the internal structure of the assembly mechanism and extending the service life of the device.

[0014] 2. This type of thermal pipeline compensator involves installing a welded pipe on one side of the compensator, with an assembly plate installed on the outside of the welded pipe. The assembly plate has several threaded grooves inside, and a splicing plate is movably installed on one side of the assembly plate. A cover pipe is installed at one end of the splicing plate, and a rubber layer is installed on the inner surface of the cover pipe. Several hexagonal screws are movably installed inside the splicing plate. The thermal pipeline is welded to the welded pipe, and the assembly plate and splicing plate are fixed together by rotating the hexagonal screws. The cover pipe can cover the welded part to prevent rainwater penetration and erosion, which could lead to structural damage and require frequent maintenance by maintenance personnel.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 - Figure 4 As shown, the technical solution provided by this utility model is as follows:

[0022] A thermal pipeline compensator includes a compensator 1. An assembly mechanism is fixedly installed on the inner side of the compensator 1. The assembly mechanism includes a flange 2, an assembly column 3, and a compression spring 4. Flanges 2 are fixedly installed at both ends of the compensator 1. Several assembly columns 3 are fixedly installed on the inner side of the flanges 2. A compression spring 4 is fixedly installed on one side of the inner side of the assembly column 3. A piston plate 5 is fixedly installed on one side of the compression spring 4. A tension spring 6 is fixedly installed at one end of the piston plate 5. A connecting rod 7 is fixedly installed inside the tension spring 6. One end of the connecting rod 7 is fixedly connected to the piston plate 5. A covering mechanism is fixedly installed at one end of the flange 2.

[0023] Through the above scheme, a flange 2 is welded to each end of the compensator 1, and four assembly columns 3 are welded to the inner side of each of the two flanges 2. A compression spring 4 is welded to one side of the inside of the assembly column 3, a piston plate 5 is welded to one side of the compression spring 4, and a tension spring 6 is welded to the other end of the piston plate 5. The other end of the tension spring 6 is welded inside the assembly column 3. A connecting rod 7 is fixedly installed inside the tension spring 6 and welded to the piston plate 5. When the compensator 1 is in operation, it will be subject to thermal expansion and contraction, causing the compensator 1 to expand and contract unpredictably. The piston plate 5 and the connecting rod 7 move inside the assembly column 3, allowing the assembly mechanism to limit the compensator 1. The installation of the compression spring 4 and the tension spring 6 makes the piston plate 5 move more smoothly inside the assembly column 3, reduces the friction of the internal structure of the assembly mechanism, and extends the service life of the device.

[0024] In this embodiment, preferably, the covering mechanism includes a welded tube 8, an assembly plate 9, and a threaded groove 10. The welded tube 8 is fixedly provided on one side of the compensator 1, and the assembly plate 9 is fixedly provided on the outer side of the welded tube 8. Several threaded grooves 10 are opened inside the assembly plate 9. A splicing plate 11 is movably provided on one side of the assembly plate 9. A covering tube 12 is fixedly provided at one end of the splicing plate 11. A rubber layer 13 is fixedly provided on the inner surface of the covering tube 12. Several hexagonal screws 14 are movably provided inside the splicing plate 11.

[0025] With the above solution, a welded pipe 8 is installed on one side of the compensator 1, and an assembly plate 9 is installed on the outside of the welded pipe 8. The assembly plate 9 has several threaded grooves 10 inside, and a splicing plate 11 is movably arranged on one side of the assembly plate 9. A cover pipe 12 is installed at one end of the splicing plate 11, and a rubber layer 13 is installed on the inner surface of the cover pipe 12. Several hexagonal screws 14 are movably arranged inside the splicing plate 11. The heat pipe is welded to the welded pipe 8. By rotating the hexagonal screws 14, the assembly plate 9 and the splicing plate 11 are fixed together. The cover pipe 12 can cover the welded part to prevent rainwater from seeping in and corroding, which would cause structural damage and require frequent maintenance by maintenance personnel.

[0026] In this embodiment, preferably, the diameter of the covering tube 12 is longer than the diameter of the welding tube 8;

[0027] With the above solution, the diameter of the covering pipe 12 is slightly longer than the diameter of the welding pipe 8, which is just enough to cover the welding pipe 8, ensuring that the covering pipe 12 can cover the rainwater and prevent the rainwater from penetrating into the welding area.

[0028] In this embodiment, preferably, the hexagonal screw 14 is movably connected to the threaded groove 10;

[0029] By using the above solution, the connection between the hexagonal screw 14 and the threaded groove 10 ensures that the hexagonal screw 14 can fix the assembly plate 9 and the splicing plate 11 together.

[0030] In this embodiment, preferably, a waterproof adhesive layer 15 is fixedly provided on one side of the splicing plate 11;

[0031] By using the above solution, the waterproof adhesive layer 15 is fixed with glue on one side of the splicing plate 11, ensuring that rainwater will not enter the interior through the gap between the splicing plate 11 and the assembly plate 9.

[0032] In this embodiment, preferably, the flange 2 has a handle groove 16 inside;

[0033] The above solution facilitates the handling of the entire device by opening a handle groove 16 inside the flange 2.

[0034] In this embodiment, a thermal pipeline compensator is used by welding a flange 2 to each end of the compensator 1. Four assembly columns 3 are welded to the inner sides of each flange 2. A compression spring 4 is welded to one side of the inner side of each assembly column 3, and a piston plate 5 is welded to one side of the compression spring 4. A tension spring 6 is welded to the other end of the piston plate 5, and the other end of the tension spring 6 is welded inside the assembly column 3. A connecting rod 7 is fixedly installed inside the tension spring 6 and welded to the piston plate 5. When the compensator 1 operates, it is subject to thermal expansion and contraction, causing it to extend and retract unpredictably. The piston plate 5 and the connecting rod 7 move within the assembly column 3, allowing the assembly mechanism to limit the compensator 1. The installation of the compression spring 4 and the tension spring 6 ensures that the piston plate 5 moves within the assembly column 3. The internal movement of the mounting column 3 is more stable, reducing the friction of the internal structure of the assembly mechanism and extending the service life of the device. By installing a welded pipe 8 on one side of the compensator 1, and an assembly plate 9 on the outside of the welded pipe 8, the assembly plate 9 has several threaded grooves 10 inside. A splicing plate 11 is movably installed on one side of the assembly plate 9, and a cover pipe 12 is installed at one end of the splicing plate 11. A rubber layer 13 is installed on the inner surface of the cover pipe 12. Several hexagonal screws 14 are movably installed inside the splicing plate 11. The heat pipe is welded to the welded pipe 8. By rotating the hexagonal screws 14, the assembly plate 9 and the splicing plate 11 are fixed together. The cover pipe 12 can cover the welded part to prevent rainwater penetration and erosion, which could lead to structural damage and require frequent maintenance by maintenance personnel.
