Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection sealing structures, in particular to a waterproof sealing device for a heat preservation pipe. Background Technique

[0002] A heat preservation pipe is short for an adiabatic pipeline, which is used for the transportation of liquids, gases and other media, and is used for the adiabatic engineering of pipelines in petroleum, chemical industry, aerospace, hot spring, military, central heating, central air conditioning, municipal engineering, etc. It is a building material with high strength and long durability. When the heat preservation pipes for urban heating enter and exit the heating operation well rooms and underground heat exchange stations and pass through facilities such as waterproof dams, they all need to pass through the walls. If these facilities are in areas with relatively high groundwater levels and are soaked in water for a long time, direct-through gaps will be generated between the outer wall of the heat preservation pipe and the wall at the wall-piercing part, resulting in seepage and leakage of water, causing the external groundwater or river water to leak into the interior of these facilities, making the indoor equipment unable to operate normally or posing on-site safety hazards.

[0003] In the prior art, there is an end sealing device for a steel-sheathed steel heat preservation pipe with the application number 202120770859.6, which includes a heat preservation pipe body. An insulation layer is arranged outside the heat preservation pipe body. A sealing component is fixedly arranged on one side of the insulation layer. The sealing component includes a pipe body, a sliding groove, a limiting groove and a clamping block. The pipe body is clamped and connected to one end of the heat preservation pipe body. A sliding groove is opened on the inner wall of the middle part of the pipe body, and the sliding groove is slidably connected to the heat preservation pipe body. A limiting groove for clamping the clamping block is opened on the inner wall of one side of the pipe body. The beneficial effects of the utility model are as follows: The heat preservation pipe body is sealed by a sealing ring and a sealing disc, and at the same time, the waterproof layer prevents the heat preservation pipe body from seeping water, effectively improving the sealing performance of the heat preservation pipe body; by driving two clamping strips to be separated from two first clamping grooves respectively by two threaded rods, the reinforcing cylinder is separated from the mounting bracket, making the disassembly, installation and maintenance of the sealing device convenient for the staff. Through multiple fixings, the sealing device has higher stability during use and is not easy to shake and fall off.
