Description

Technical Field

[0001] The utility model relates to the technical field of pipeline installation, in particular to a limiting bracket for pipeline cold insulation installation. Background Art

[0002] Cold preservation generally refers to cryogenic pipes. Cryogenic pipes refer to seamless steel pipes suitable for -45℃~-195℃ low-temperature pressure vessel pipes and low-temperature heat exchanger pipes. Their function is to transport fluid media, transfer fluid power and information. They are suitable for transporting refrigerants in equipment in industries such as petrochemicals, refrigeration, and shipbuilding. Cryogenic pipe supports are used to bear pipeline loads, limit pipeline displacement, control pipeline vibration, and transfer loads to various components or devices on the bearing structure. Cryogenic pipe supports are an important component for maintaining pipeline stability and ensuring safe operation of pipelines.

[0003] During the installation and use of the existing pipeline, since there is no pipeline displacement structure, the two groups of pipelines need to be aligned and connected. After the pipeline is installed, if there is any misalignment, workers are required to dismantle the pipeline, causing rework problems; since there is no protective layer for the low-temperature pipeline cold insulation layer, the cold insulation layer is in direct contact with the outside world, which reduces the cold insulation life and effect, and brings certain adverse effects to people's use process. In order to solve the shortcomings of the existing technology, we propose a limit bracket for pipeline cold insulation installation. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 4 As shown, a limit bracket for pipeline cold insulation installation, the material of the upper pipe clamp 1 and the lower pipe clamp 13 can be 316 stainless steel, the material of the gasket 11 is Teflon material, the upper pipe clamp 1 and the lower pipe clamp 13 are fixed to the gasket 11 by bolts, the material of the insulation layer 3 can be glass wool, the sealing ring layer 4 can be galvanized aluminum plate, and the insulation layer 3 is bonded between the sealing ring layer 4 and the aluminum outer layer 2 by metal glue.

[0024] It should be noted that the utility model is a limit bracket for pipeline cold insulation installation. When in use, the user places the low-temperature pipeline inside the sealing ring layer 4, so that there can be thermal isolation between the low-temperature pipeline and the outside world. The combination of the aluminum outer layer 2, the insulation layer 3 and the sealing ring layer 4 can block the external heat from entering the pipeline while insulating, causing the temperature and pressure of the medium inside the pipeline to increase, resulting in cold loss and safety risks.

[0025] At the same time, the nuts at both ends of the first screw rod 8 are screwed inward, so that the upper pipe clamp 1 and the lower pipe clamp 13 are close to each other, and the washer 11 is close to the outer layer 2 of the aluminum skin, so as to realize radial and axial limitation of the pipeline. When installing the pipeline, it is necessary to align the connection between the two groups of pipelines, and the mounting seat 6 is installed on the ground through the bolt 16. The motor 7 drives the second screw rod 14 to rotate, and the second screw rod 14 drives the movable frame 15 to move forward and backward, so that the fixed frame 10 moves forward and backward, and the upper pipe clamp 1 and the lower pipe clamp 13 clamp the pipeline to move forward and backward, so as to avoid the need to disassemble and reassemble the pipeline for alignment after the pipeline is manually installed.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
