Abstract
The utility model relates to a multi-directional expansion compensator and the design for improving a heat distribution pipeline, particularly a flexible compensation apparatus which is suitable for the thermal expansion of the pipeline of coal powder and the demand of the additional displacement of a combustor. The utility model adopts that a middle connecting pipe is connected with two corrugated assemblies and a flexible multi-directional expansion compensator which can adsorb the spatial displacement with any directions; each corrugated assembly comprises a transversal corrugated cylinder with a thin wall, a working connecting pipe with a thick wall, a conical tube member, etc. The utility model solves various problems of a traditional filling type compensator of leakage, blocking in hot state, etc. When in use; the utility model has the advantages of reliable displacement absorption, pressurization, heat resistance, simple structure and convenient installation and repairing.
Description
The utility model relates to a kind of compensation device that improves the heat distribution pipeline design, especially for a kind of flexible multidirectional expansion appliance that absorbs pulverized coal channel thermal expansion and burner additional displacement amount.
Firepower electrical plant boiler coal-ash pipeline hangs layout with the space usually at present, remove the thermal walking that will absorb pulverized coal channel, also to absorb the thermal walking of boiler water wall, and require displacement to be multi-direction and displacement amount big, and the thermal walking compensation problem of pulverized coal channel is difficult problem always.The material filling type compensator that uses is used for bit shift compensation at present following several types: slip-type expansion joint is that single nose balance, hinge compensator is that single angle offset compensation, three-dimensional compensator are realized axially and angular compensatory simultaneously.But, the material filling type compensator that these are traditional, owing to defective on this body structure and the filler that adopts two slide or rotation surface between sealing means have following problem: easily produce in the use hot stuck, absorb that displacement is not good, that piping is expanded is not smooth; Pulverized coal channel is excessive to the burner additional moment, burner can not be realized hot swing; The stuffing box packing resistance to heat is poor, does not possess enough elasticity and pliability, causes a large amount of wind, powder to leak; Installation requirement is tighter, often because alignment error also can cause leakage.Owing to have above-mentioned variety of issue, and make compensator lose due function, had a strong impact on the power plant safety economical operation.
The utility model purpose is for overcoming the above problems, a kind of multidirectional expansion appliance of new structure is provided, satisfying the demand of pulverized coal channel thermal expansion.
The utility model is achieved in that the thin walled cylinder with transverse wave, and higher bearing capacity is arranged, and the very big and very little performance of axial rigidity of radial rigidity is arranged.The technical solutions of the utility model main points: the protection ring flat-plate etc. that has work adapter, the Taper Pipe parts of the thin walled cylinder of transverse wave and heavy wall and be provided with purge hole constitutes the ripple assembly parts.Two isostructure ripple assembly parties are connected by middle adapter, have realized axial stretching and horizontal, angle deflection, can absorb the flexible multidirectional compensation device of space any direction displacement.
The utility model has solved the variety of issue that the material filling type compensator exists, sew in having avoided using, hot stuck phenomenon, have that the displacement of absorption is reliable, withstand voltage, heat-resisting, a long service life, simple in structure, in light weight, advantage such as installation is simple, easy to maintenance, cost is lower.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:
The multidirectional expansion appliance structural representation of Fig. 1 (table number is in related description)
Below in conjunction with Fig. 1 the utility model is further described:
Thin walled cylinder (9) with transverse wave (6) is made of wall thickness 1-2mm Thin Stainless Steel sheet metal forming.One end of thin walled cylinder (9) and Taper Pipe parts (7) welding, the other end is taken over (1) by protection ring flat-plate (5) and work and is connected and composed the ripple assembly parts.Ring flat-plate (5) is provided with several purge holes (10) along circumference tool certain intervals and is connected with coil pipe (3), and is connected with external air source by flange (4), and gas flows along the medium direction, prevents that effectively pipeline powder coal from accumulating.Middle adapter (2) is taken over the isometrical guide shell effect that has been communicated with work, adopts the transition of thickening Taper Pipe parts, and tapering is advisable with 20 °-30 °, makes it to reduce wear, reduces flow resistance and guaranteed circulation area simultaneously.Two isostructure ripple assembly parties are connected by longer middle adapter (2), have flexible and deflection deformation performance, absorb space any direction displacement performance simultaneously, have changed conventional filler formula structure.In the thin walled cylinder outside bolt, nut (8) are housed, control its product and in the transportation installation process, be out of shape.
