Description
Technical field
The utility model relates to a kind of direct-buried steam pipeline, is specifically a kind of direct-buried steam pipeline with novel interior rolling structure.
Background technique
Direct-buried steam pipeline outer rolling structure, for when working steel tube generation thermal walking, itself and thermal insulation layer are synchronized with the movement as a whole, and interior rolling structure is then contrary with it, and the motion mode of working steel tube and thermal insulation layer is relative movement.Relative to outer rolling structure, interior rolling structure can make working steel tube be independent individual, can freely extend or compress when pipeline performance or stopping, do not destroy thermal insulating material, with regard to domestic existing each interior rolling structure, still there is many difficult problems being difficult to overcome, as: how to realize being separated completely of working steel tube and thermal insulation layer, the destruction of when how to reduce parent material thermal walking, thermal insulation layer being caused, how to reduce the heat transfer of rolling support, how to make workshop be achieved in output and batch, how to make manufacture cost increase substantially.
Summary of the invention
In view of the difficult problem that existing interior rolling structure cannot overcome, the purpose of this utility model to provide a kind of novel interior rolling drag reduction formula steam line, reduce the heat transfer of rolling support, reduce tube friction and solve difficult each difficult problem be separated completely with thermal insulation layer difficulty with working steel tube of preparation process, realize the complete of thermal insulation layer, guarantee working steel tube free displacement, the safe operation of pipeline.
The utility model provides a kind of novel interior rolling drag reduction formula steam line, comprises working steel tube, external protective steel tube, thermal insulation layer, rolling support; Rolling support, thermal insulation layer are arranged between external protective steel tube and working steel tube, and rolling support, thermal insulation layer and external protective steel tube are fixed as an entirety, are provided with gap between thermal insulation layer and working steel tube; Rolling support is made up of clamp, ring flat-plate, roller, roller bearing, and roller is arranged on roller bearing, and roller bearing is fixed on ring flat-plate draw-in groove place, and ring flat-plate is fixedly connected with clamp, and clamp is fixedly connected with external protective steel tube inwall, and roller contacts with working steel tube outer surface line.Thermal insulation layer is multilayer, and its one deck pressing close to working steel tube is hard insulating material.Working steel tube outer surface spiral winding tinfoil, the thickness of tinfoil is 0.1 millimeter to 0.3 millimeter.Roller is arranged on roller bearing, and roller bearing is fixed on ring flat-plate draw-in groove place, and be pushed into behind straight tube pre-position by the ring flat-plate with roller, ring flat-plate is fixedly connected with clamp.Hard insulating material is the cotton thermal-insulating pipe case of modular glass.
The beneficial effects of the utility model are: roller contacts with working steel tube outer surface line, and heat is successively passed to external protective steel tube by roller, roller bearing, ring flat-plate, clamp, reduce heat transmission step by step, less loss, reduce external protective steel tube surface temperature.Working steel tube surface wrap tinfoil, thickness is 0.1 millimeter to 0.3 millimeter, both reduced friction, tinfoil reflecting heat principle is utilized again to reduce heat waste as far as possible, suitable thickness is convenient to parcel working steel tube surface simultaneously, is convenient to external protective steel tube, rolling support and thermal insulation layer and integrally and between working steel tube relative movement occurs.Ring flat-plate with roller and clamp are positioned between external protective steel tube and working steel tube, play the effect ensureing with one heart, support, and with the displacement of limit thermal insulation layer, ensure the complete of thermal insulation layer.Simply, cost is low for pipeline manufacturing process and structure, easily realizes batch production.
