Abstract
The utility model relates to a novel turbine insulating sleeve which is simple in structure, convenient to mount and dismount, good in insulating effect and repeatable. The novel turbine insulating sleeve comprises at least one insulating layer arranged on the outer surface of the turbine with bolts and composed of a plurality of mutually spliced insulating blocks. A protection layer composed of a plurality of mutually spliced protection blocks are covered outside the insulating layer, and a plurality of through holes corresponding to the bolts on the turbine are arranged on the insulating blocks.
Description
Technical field
The utility model relates to a kind of Novel steam turbine lagging.
Background technique
The Insulation of steam turbine is with thermal insulating materials such as slag wool, glass wools, it to be wrapped up at present, with glass fibre cloth or ribbon, thermal insulating material is fixed on steam turbine casing again, coat again at last the upper iron sheet of coal tar or wrapping, although this heat preserving mode also can reach the purpose of insulation, but when installing during this heat preserving mode construction, be difficult to thermal insulating material is wrapped up steam turbine casing according to suitable size, can produce the space between thermal insulating material and steam turbine casing, or can cause the loss of heat, heat insulation effect is bad; Waterproof ability is poor, and steam turbine casing easily is corroded, and user cost is high; Can only disposablely use, if must complete dismounting when running into maintenance, cause the wasting of resources, cost of labor is high; Complex installation process, make troubles to the workmen.
China Patent No. is: the open turbine flexible heat insulating cover of ZL 200520009055.5, it is comprised of a plurality of insulation block splicings designed according to the steam turbine profile, described insulation block is three layers: its liner, protective layer adopt high temperature resistant composite coating fibre cloth, its thermal insulation layer adopts the high-temperature-resistant thermal-insulation material, be fixed on protective layer the high temperature resistant sewer of surrounding with high temperature resistant rivet; Connect with regulating high temperature resistant rope or high-temperature resistant fiber band between described each insulation block.This patent has solved above-mentioned technical problem well, but is fixed on protective layer with high temperature resistant rivet because its means of fixation adopts thermal insulation layer, makes thermal insulation layer and steam turbine fit not tight, and heat insulation effect is unsatisfactory; And need comparatively inconvenience during assembling and disassembling, easily destroy protective layer or thermal insulation layer, cause not reproducible utilization.
Summary of the invention
Therefore, for above-mentioned problem, the Novel steam turbine lagging that the utility model proposes a kind of simple in structure, easy accessibility, high insulating effect, can reuse.
For achieving the above object; the utility model has adopted following technological scheme: the Novel steam turbine lagging; comprise that one deck at least is located at the thermal insulation layer with the steam turbine outer surface of bolt; described thermal insulation layer is comprised of the insulation block that several splice mutually; described thermal insulation layer is wrapped with the protective layer that one deck is comprised of several protection pieces that mutually splice, described insulation block be provided with steam turbine on corresponding several through holes of bolt.
Further, described thermal insulation layer is two-layer, and between the insulation block in described two-layer thermal insulation layer, the fissure of displacement is stacked.
Further, described insulation block is the aluminum silicate insulation material layer.
Further, described each insulation block is provided with hasp, and the mode by the steel wire winding hasp between described adjacent insulation block is connected successively.
Further, described protection piece is nanometer composite layer.
Further, the described piece of respectively protecting is provided with hasp, and the mode by the steel wire winding hasp between described adjacent protection piece is connected successively.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: compare with existing steam turbine lagging, this lagging is tightr with the steam turbine applying, high insulating effect, and assembling and disassembling is easy, and material is reusable; And adopt the mode that adopts the fissure of displacement to be stacked between each thermal insulation layer, better heat preservation.
