[0002] With the development of urban centralized heating, the construction scale of thermal pipelines is getting larger and larger, and their applications are becoming more and more extensive. In the field of engineering construction, the method of compensating for thermal displacement of straight thermal pipelines is mainly to achieve pipeline displacement compensation through the coordination of two sets of rotating compensators.

[0003] Since thermal pipes are directly exposed to the outdoor environment, they are easily polluted and eroded by dust, droplets, etc. On the one hand, they are easily deformed by external impacts and thermal expansion and contraction of the pipes. In severe cases, they may even cause leakage or rupture of the thermal pipes.

[0004] To this end, we propose a special composite casing device for thermal pipelines. Utility Model Content

[0012] Beneficial Effects

[0013] The utility model provides a composite casing device for thermal pipelines, which has the following beneficial effects:

[0014] (1) A composite casing device specially used for a thermal pipeline. When the casing is used, check whether all structures are complete, open the upper casing and the lower casing by hinges, insert them into the outside of the pipeline body, and then rotate the bolts to insert them into the fixing plate to ensure the fixation of the upper casing and the lower casing. The outer clamping plate of the pipeline body presses the push rod, and the return spring inside the slider changes the distance between the clamping plates, so that the device can be applied to pipeline bodies of various specifications, thereby increasing the application range of the device.
