Abstract
Description
Technical Field
[0001] This utility model relates to the field of natural gas transmission pipeline technology, and in particular to a thermal insulation structure for natural gas transmission pipelines that reduces transmission losses. Background Technology
[0002] Natural gas refers to all gases that exist naturally in the world, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere. Natural gas transportation requires pipelines; however, due to temperature variations, natural gas pipelines in cold regions can freeze, causing losses during transportation. Insulation structures are typically used to protect them.
[0003] Existing technology, such as the water supply pipeline insulation structure disclosed in patent number CN202422302199.5, relates to the field of water supply pipeline technology. It includes a pipeline body and two insulation shells, with a connecting mechanism between the two insulation shells. The connecting mechanism includes two first arc-shaped blocks and two second arc-shaped blocks, each first arc-shaped block having two symmetrical sliding holes on its surface. This utility model, by providing a connecting mechanism, facilitates future maintenance of the water supply pipeline. When maintenance is required, the insulation structure can be manually removed from the pipeline without damaging it. This improves both the effectiveness and efficiency of the water supply pipeline insulation structure.
[0004] The disadvantage of the above-disclosed insulation structure is that it cannot be adapted to natural gas transmission pipelines of different diameters, and its applicability is limited. Therefore, we have designed a natural gas transmission pipeline insulation structure to reduce transmission losses. Utility Model Content

The two measuring tape limiting plates are respectively inserted inside the pipeline connecting rings and can be rolled up. An angle code is installed at one end of each of the two measuring tape limiting plates. Each angle code is provided with a bolt locking part. A fastening nut is connected to the threaded part of the bolt locking part. A support column is installed at the bottom end of each pipeline connecting ring. Fixed support feet are installed at the bottom ends of the two support columns. A straight groove is opened on the surface of each support column, and the bolt locking part is located inside the corresponding straight groove.
[0007] Preferably, an insulation strip is provided between the two pipe connection rings, one end of the insulation strip is fitted with a clamping seat, and one end of the clamping seat is fitted with an energy-absorbing block.
[0008] Preferably, the insulation tape includes a pearl cotton layer, a heat insulation layer, a fixing layer, and a rubber protective layer, which are distributed sequentially.
[0009] Preferably, the outer surface of the insulation tape is fitted with a linear binding strap, one end of which is provided with a movable pin, and the tail end of which is provided with a fixing ring.
[0010] Preferably, a pin retaining sleeve is installed at the top of one of the pipe connection rings, and the pin retaining sleeve is inserted into the movable pin and limited by the retaining ring sleeve.
[0011] Preferably, a magnetic connecting strip is provided at one edge of the insulation strip, and the magnetic connecting strip magnetically attracts the other edge of the insulation strip.
[0012] The technical effects and advantages of this utility model are as follows: By setting two pipe connecting rings and two measuring tape limiting plates, the two measuring tape limiting plates are respectively inserted inside the pipe connecting rings and can be rolled up. Angle code plates are installed at one end of each measuring tape limiting plate, and each angle code plate is provided with a bolt locking part. The threaded part of the bolt locking part is connected to a fastening nut. In this way, the diameter of the pipe connected by the pipe connecting ring can be easily changed by adjusting the rolling up of the measuring tape limiting plates. It has a good usage effect and can better cope with different pipes. Attached Figure Description
