Background

The energy source is the life pulse of national economy. Under the condition of the rapid increase of the current energy consumption, the energy-saving and emission-reducing work must be deeply promoted. At present, the heat is gradually supplied in a centralized way to gradually replace a coal-fired small boiler. However, according to the existing condition design, the heat dissipation loss of the centralized heat supply pipeline accounts for 5-20% of the total heat, and the influence of the pipe bracket on the heat dissipation loss is very large.

The medium temperature changes in the pipeline and can cause the condition of expansion with heat and contraction with cold of the pipeline, thereby the pipeline warp and leads to stress and displacement change, because the pipeline is not a straight tube, the displacement direction is uncertain. The existing heat insulation pipe bracket needs to put the pipe bracket supporting a pipeline on a slidable sliding plate, utilizes a plate body between a bottom plate at the bottom of the pipe bracket and a lower sliding plate to bear the pipeline, and adapts to stress and displacement change caused by expansion with heat and contraction with cold through friction between the plate bodies. However, the friction force of the heat insulation pipe support is large, the effect is not ideal, and if the friction force needs to be reduced, the cost of production raw materials is large. CN201034215Y discloses a rolling sliding heat insulation pipe support, which changes the sliding friction force of transmission into rolling friction, thereby reducing the friction coefficient and saving the production cost. However, the rolling body is designed at the bottom of the supporting seat, and during bottom rolling, the contact area of the bottom rolling body is small, the pressure at the rolling friction position is large, and the safety and the service life are doubtful.
