Description

Technical Field

[0001] The utility model relates to the field of heating pipelines, in particular to an earthquake-resistant and heat-insulating thermal pipeline. Background Art

[0002] With the continuous acceleration of my country's urbanization process, the demand for urban heating is also increasing. Urban centralized heating has many excellent characteristics, so it has been widely used in various cities, bringing great convenience and benefits to people living in various cities. However, most of the current urban heating pipelines do not consider the seismic function during design, and the pipelines will be damaged when they are vibrated. The patent document with application number 202120704099.9 in the prior art proposes a seismic-resistant and heat-insulating heating pipeline. When vibration occurs, the telescopic rod moves up and down in the telescopic cylinder, which solves the problem of poor seismic resistance of the heating pipeline.

[0003] In the above technical solution, both ends of the pipeline are fixedly connected with connecting pipes, and the connecting pipes are welded to ensure that the pipeline can flow the medium normally. However, after the two pipelines are welded end to end, due to the lack of a reinforcement support mechanism for the connection between the two pipelines, the seismic performance of the connection is poor, which will cause leakage at the pipeline connection when subjected to multiple vibrations. For this reason, we propose a seismic-resistant thermal insulation pipeline. Summary of the invention

[0004] The purpose of the utility model is to solve the problem that the prior art lacks a reinforcing support mechanism for the connection between two pipes, resulting in poor seismic performance of the connection and leakage at the pipe connection when subjected to multiple vibrations, and to propose a seismic-resistant and heat-insulating thermal pipe.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A seismic-resistant and heat-insulating thermal pipeline comprises a base and two pipeline bodies arranged on the top of the base, characterized in that a flange is arranged on one side of the two pipeline bodies, clamps are arranged on the upper and lower sides of the two flanges, double-headed screws are penetrated on the front and back sides of the two clamps, and springs are mounted on the parts of the double-headed screws located at the two clamps; a bracket is arranged between the clamps located on the lower side of the flange and the base, and a buffer mechanism is arranged at the bottom of the bracket. Through the above-mentioned setting structure, when the clamps are vibrated, the distance between the two clamps changes, and the springs undergo elastic deformation to absorb part of the impact force.

[0007] In some embodiments, the bracket is an H-shaped structure, and the buffer mechanism is arranged in a one-to-one correspondence with the two vertical sides of the bracket. The buffer mechanism includes a mounting plate connected to the bracket and a connecting plate located on the upper side of the mounting plate, and the bracket is arranged through the connecting plate; disc springs are arranged between the connecting plate and the mounting plate, and between the base and the mounting plate, and the disc spring, the connecting plate and the mounting plate are jointly penetrated by a bolt; a threaded hole is opened on the base, and the bolt is threadedly connected in the corresponding threaded hole.

[0008] In some embodiments, a rubber pad is provided on one side of the two clamping plates close to the flange, and the rubber pad is located between the two double-headed screws.

[0009] In some embodiments, both flanges are symmetrically provided with bosses, which penetrate the rubber pads. The clamping plate is provided with grooves matching the bosses, which are sleeved on the outside of the bosses through the grooves, thereby limiting the deviation of the two flanges.

[0010] In some embodiments, the pipeline body includes an outer pipe and a steel pipe sleeved inside the outer pipe, and an insulation layer is arranged between the outer pipe and the steel pipe. The insulation layer plays a role of insulation.

[0011] In some embodiments, the two flanges are connected by bolt 2, and nuts are mounted on the bolt 2 and the double-headed screw.

[0012] Compared with the prior art, the utility model provides a seismic-resistant and heat-insulating thermal pipeline, which has the following beneficial effects.

[0013] The utility model arranges flanges on one side of two pipes, and clamping plates are arranged on the upper and lower sides of the two flanges, and double-headed screws are penetrated on the front and rear sides of the two clamping plates, and the parts of the double-headed screws located at the two clamping plates are sleeved with springs. After installation, the two clamping plates are sleeved on the outer side of the flanges to reinforce and support the connection between the two pipes, and a bracket is arranged between the clamping plates located at the lower side of the flanges and the base, and a buffer mechanism is arranged at the bottom of the bracket. Through the above-mentioned setting structure, when the base vibrates, the bracket firstly buffers under the action of the disc spring, thereby generating a buffering protection force, effectively reducing the vibration transmitted from the base to the bracket, and as the vibration is further transmitted to the clamping plates, the spacing between the two clamping plates changes, and the spring undergoes elastic deformation to absorb part of the impact force, thereby improving the seismic resistance, effectively solving the problem of poor seismic performance at the connection between the two pipes in the prior art, which causes vibration at the pipe connection and thus leakage at the connection.

[0014] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model absorbs part of the impact force through elastic deformation of the spring and the disc spring, thereby improving the seismic resistance of the pipeline.

[0015] Other advantages, objectives and features of the present invention will be described in the following description to some extent; and will be apparent to those skilled in the art based on the following examination and study to some extent; or, may be taught from the practice of the present invention.

Through the above-mentioned setting structure, the distance between the two clamping plates 4 changes when vibrated, and the spring 6 undergoes elastic deformation to absorb part of the impact force.

[0025] Please refer again Figure 3 The bracket 7 is an H-shaped structure, and the buffer mechanism is arranged in a one-to-one correspondence with the two vertical sides of the bracket 7. The buffer mechanism includes a mounting plate 8 connected to the bracket 7 and a connecting plate 9 located on the upper side of the mounting plate 8, and the bracket 7 is arranged through the connecting plate 9; disc springs 10 are arranged between the connecting plate 9 and the mounting plate 8, and between the base 1 and the mounting plate 8, and the disc springs 10, the connecting plate 9 and the mounting plate 8 are jointly penetrated by bolts 11; a threaded hole 12 is opened on the base 1, and the bolt 11 is threadedly connected in the corresponding threaded hole 12. Through the above-mentioned setting structure, the bracket 7 is first buffered under the action of the disc spring 10, thereby generating a buffering protection force, which effectively reduces the vibration transmitted from the base 1 to the bracket 7.

[0026] In this embodiment, a rubber pad 13 is provided on one side of the two clamping plates 4 close to the flange 3 . The rubber pad 13 is located between the two double-headed screws 5 . The rubber pad 13 can protect the surface of the flange 3 .

[0027] Please refer again Figure 4 The two flanges 3 are symmetrically provided with bosses 14, which penetrate the rubber pad 13. The clamping plate 4 is provided with a groove 15 that matches the boss 14. The groove 15 is sleeved on the outer side of the boss 14, thereby limiting the deviation of the two flanges 3.

[0028] Please refer again Figure 5 The pipeline body 2 includes an outer tube 201 and a steel tube 202 sleeved inside the outer tube 201. An insulation layer 203 is provided between the outer tube 201 and the steel tube 202.

[0029] The working principle of the utility model is:

[0030] When in use, the two pipe bodies 2 are connected through the flange 3 and fixed with bolts 16 and nuts 17. Then, the bosses 14 of the two flanges 3 are operated to be inserted into the grooves 15 of one of the clamping plates 4, and then the other clamping plate 4 is covered. The flange 3 is placed between the two clamping plates 4. Then, the spring 6 and the stud screw 5 are held and the stud screw 5 is operated to pass through the spring 6. Finally, the clamping plates 4 are limited by the nuts 17 to complete the closing of the two clamping plates 4. The state after the installation is completed is as follows: Figure 1 As shown, two clamping plates 4 are sleeved on the outer side of the flange 3 to reinforce and support the connection between the two pipe bodies 2.
