Description

Technical Field

[0001] This utility model relates to the field of pipeline installation technology, and more specifically to a connection structure for installing cold water pipelines. Background Technology

[0002] Cooling pipes are part of a centralized cooling system, responsible for delivering cooling capacity to various buildings. Cooling water pipes use water as a medium to deliver cooling capacity. During the cooling water delivery process, cooling sub-pipes need to be installed on the surface of the cooling main pipe, and installation connection structures are required during installation.

[0003] Currently, when connecting cooling sub-pipes and cooling main pipes, the common method is to directly use bolts to connect flanges to ensure the pipe connection is firm and airtight. However, for cooling water pipes, which are used to transport low-temperature brine during use and are at room temperature when not in use, there is a significant temperature difference. This results in the pipe connection being subject to greater thermal expansion and contraction during installation, making it prone to deformation and leakage under tension and compression, thus affecting the tightness of the cooling water pipe connection.

[0004] In view of this, the present invention proposes a cooling water pipeline installation and connection structure to solve this problem. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cooling water pipeline installation and connection structure to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a cooling water pipeline installation and connection structure, including a cooling main pipe and a cooling sub-pipe disposed on the surface of the cooling main pipe, wherein a branch pipe is welded to the side wall of the cooling main pipe, and a connecting component is provided between the branch pipe and the cooling sub-pipe;

[0007] The connecting assembly includes an extension frame fixedly installed on the surface of the branch pipe, a limit slide rod fixedly installed on the surface of the extension frame, a connecting flange slidably connected to the surface of the limit slide rod, a bellows fixedly connected between the connecting flange and the branch pipe, and the connecting flange being fixedly connected to the cooling sub-pipe by mounting bolts.

[0008] A conductive spring is fixedly installed on the left side of the connecting flange, a contact switch is fixedly installed on the left end of the limiting slide rod, and a warning element is fixedly installed on the surface of the cooling main pipe. The conductive spring, contact switch, and warning element are all electrically connected to the external central control room.

[0009] Furthermore, the number of the extension frame and the limiting slide bar is three, and the three extension frames are arranged in a circumferential array on the surface of the branch pipe.

[0010] As a further description of the above technical solution: by setting three limit slide rods, the stability of the connecting flange during sliding can be ensured.

[0011] Furthermore, an electronic thermometer is embedded on the surface of the cooling main pipe, and the electronic thermometer is connected to the signal of the external central control room.

[0012] As a further description of the above technical solution: by setting up an electronic thermometer, the temperature of the brine inside the cooling main pipe can be monitored remotely.

[0013] Furthermore, a sealing groove is provided between the adjacent surfaces of the connecting flange and the cooling subpipe, and a sealing ring is provided inside the sealing groove.

[0014] As a further description of the above technical solution: by setting a sealing groove and a sealing ring, the sealing performance between the connecting flange and the cooling subpipe can be improved.

[0015] Furthermore, a protective ring is fixedly installed on the side of the connecting flange away from the cooling sub-pipe, and a temperature-controlled heating ring is fixedly installed on the inner wall of the protective ring, with the temperature-controlled heating ring corresponding to the position of the sealing ring.

[0016] As a further description of the above technical solution: by setting a temperature-controlled electric heating ring, the connecting flange and sealing ring can be continuously heated and kept warm during the continuous cold brine transportation process. This ensures that the operating temperature of the sealing ring is relatively stable, preventing damage to the sealing ring due to repeated deformation caused by temperature differences before and after the use of the cold water pipeline, and ensuring the sealing effect of the sealing ring.

[0017] Furthermore, the warning device is an audible and visual alarm. When the conductive spring contacts the contact switch, the warning device is energized and emits an alarm.

[0018] As a further description of the above technical solution: when the cooling sub-tube shortens due to cold contraction, causing the conductive spring to move to the left and contact the contact switch, the warning device will sound an alarm to alert the staff and remind the user to check and observe to ensure that the length of the limit slide rod meets the deformation requirements of the cooling sub-tube.

[0019] The technical effects and advantages of this utility model are as follows:

[0020] 1. Compared with existing technologies, this cooling water pipeline installation and connection structure utilizes a cooling main pipe to transport low-temperature brine, connecting the cooling sub-pipes and branch pipes to achieve the purpose of transporting low-temperature brine to external equipment for cooling. By setting up connection components, the length of the cooling sub-pipe will change due to thermal expansion and contraction during use. The connecting flange slides on the surface of the limiting slide bar, thereby driving the corrugated pipe to expand and contract, which can adaptively adjust the length and avoid deformation and leakage at the connection between the branch pipe and the cooling sub-pipe due to deformation and compression, ensuring the smooth operation of cooling. Furthermore, by setting up conductive springs, contact switches, and warning devices, when the cooling sub-pipe shortens due to cold contraction, causing the conductive spring to move to the left and contact the contact switch, the warning device will sound an alarm to alert the staff and remind the user to check and observe to ensure that the length of the limiting slide bar meets the deformation requirements of the cooling sub-pipe.

[0021] 2. Compared with existing technologies, this chilled water pipeline installation and connection structure, through the installation of an electronic thermometer, can remotely monitor the temperature of the brine inside the chilled water main pipe; through the installation of a sealing groove and a sealing ring, it can improve the sealing performance between the connecting flange and the chilled water sub-pipe; through the installation of a temperature-controlled electric heating ring, it can continuously heat and insulate the connecting flange and the sealing ring during continuous chilled water supply, making the operating temperature of the sealing ring more stable and avoiding damage to the sealing ring due to repeated deformation caused by temperature differences before and after the chilled water pipeline is used, thus ensuring the sealing effect of the sealing ring.

The cooling water pipe installation and connection structure involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Reference Figures 1 to 4 This utility model provides a cooling water pipeline installation and connection structure, including a cooling main pipe 1 and a cooling sub-pipe 2 disposed on the surface of the cooling main pipe 1, and a branch pipe 3 welded to the side wall of the cooling main pipe 1.

[0029] The cooling water pipeline installation and connection structure utilizes the cooling main pipe 1 to transport low-temperature brine, and connects the cooling sub-pipe 2 to the branch pipe 3 to achieve the purpose of transporting low-temperature brine to external equipment for cooling treatment.

[0030] A connecting component is provided between branch pipe 3 and cooling sub-pipe 2.

[0031] The connecting assembly includes an extension frame 4 fixedly installed on the surface of the branch pipe 3, and a limiting slide rod 5 fixedly installed on the surface of the extension frame 4. There are three extension frames 4 and three limiting slide rods 5 arranged in a circumferential array on the surface of the branch pipe 3.

[0032] The surface of the limiting slide bar 5 is slidably connected to the connecting flange 6, and the connecting flange 6 is fixedly connected to the branch pipe 3 by a bellows 7. The connecting flange 6 is fixedly connected to the cooling sub-pipe 2 by mounting bolts.

[0033] By setting up a connecting component, the length of the cooling sub-pipe 2 will change due to thermal expansion and contraction during use. The connecting flange 6 slides on the surface of the limiting slide bar 5, thereby causing the bellows 7 to expand and contract. This allows for adaptive length adjustment, preventing deformation and leakage at the connection between the branch pipe 3 and the cooling sub-pipe 2 due to deformation and compression, thus ensuring the smooth operation of the cooling operation.

[0034] A sealing groove is provided between the adjacent surfaces of the connecting flange 6 and the cooling sub-pipe 2, and a sealing ring 12 is provided inside the sealing groove.

[0035] By setting a sealing groove and a sealing ring 12, the sealing performance between the connecting flange 6 and the cooling sub-pipe 2 can be improved.

[0036] A protective ring 13 is fixedly installed on the side of the connecting flange 6 away from the cooling sub-pipe 2. A temperature-controlled heating ring 14 is fixedly installed on the inner wall of the protective ring 13, and the position of the temperature-controlled heating ring 14 corresponds to that of the sealing ring 12.

[0037] By setting up a temperature-controlled electric heating ring 14, during the continuous cold brine transportation process, the temperature-controlled electric heating ring 14 can continuously heat and insulate the connection flange 6 and the sealing ring 12, making the operating temperature of the sealing ring 12 more stable. This avoids damage to the sealing ring 12 due to repeated deformation caused by temperature differences before and after the use of the cold water pipeline, thus ensuring the sealing effect of the sealing ring 12.

[0038] A conductive spring 8 is fixedly installed on the left side of the connecting flange 6, a contact switch 9 is fixedly installed on the left end of the limiting slide bar 5, and a warning element 10 is fixedly installed on the surface of the cooling main pipe 1.

[0039] The warning element 10 is an audible and visual alarm. When the conductive spring 8 and the contact switch 9 come into contact, the warning element 10 is energized and emits an alarm.

[0040] Furthermore, by setting a conductive spring 8, a contact switch 9, and a warning element 10, when the cooling sub-tube 2 shortens due to cold contraction, causing the conductive spring 8 to move to the left and contact the contact switch 9, the warning element 10 will sound an alarm to alert the staff and remind the user to conduct inspection and observation to ensure that the length of the limit slide bar 5 meets the deformation requirements of the cooling sub-tube 2.

[0041] An electronic thermometer 11 is embedded on the surface of the cooling main pipe 1, and the electronic thermometer 11 is connected to the signal of the external central control room.

[0042] The cooling water pipeline installation and connection structure, by setting up an electronic thermometer 11, can remotely monitor the temperature of the brine inside the cooling water main pipe 1.
