Abstract
The utility model relates to a steel plastic casing joint for steam pipelines, which is used for connecting steel bushings and plastic bushings in steam pipelines. The utility model comprises a steel pipe, a steel bushing, a plastic bushing, an inorganic insulating layer, an organic insulating layer, a steel sleeve, a sealing glue layer, a heat shrinking sleeve and resin glass cloth. The utility model has the advantages of good thermal-insulating and waterproof properties and excellent expansion and shrinking performance, and the utility model can be used for repairing openings of directly buried steam pipelines with steam of 150 to 320 DEG and pipe diameters of 150 to 1020 mm.
Description
The utility model relates to a kind of steel of steam line-mould sleeve joint, is used for being connected of steam line Steel Sleeve and plastic bushing.
Insulation, the sealing configurations that adopt Steel Sleeve such as the fixed support of existing steam line, FlexbleJoint, elbow, threeway more, and the straight tube of steam line adopts insulation, the sealing configuration of plastic bushing more, interface between Steel Sleeve and plastic bushing adopts shrink belt or the cold adhesive tape that twines to seal, because at high temperature adhesion strength descends, produce projection, slip and influence sealing.And for example adopt resin, glass cloth sealing, owing to make the waterproof sealing effect bad with the not firm appearance cracking of Steel Sleeve bonding.
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art and the steel of the good steam line of a kind of insulation, sealing effect-mould sleeve joint is provided.
The purpose of this utility model can reach by following measure.
The steel of steam line of the present utility model-mould sleeve joint, comprise steel pipe 1, steel pipe 2, it is characterized in that Steel Sleeve 3 being arranged at the outer surface of steel pipe 1, outer surface at steel pipe 2 has plastic bushing 4, annular space between steel pipe 1 outer surface and Steel Sleeve 3 is inorganic insulating layer 5 and organic heat-insulating layer 6, annular space between steel pipe 2 outer surfaces and plastic bushing 4 is inorganic insulating layer 5 and organic heat-insulating layer 6, steel bushing sleeve 7 is arranged in the outside of Steel Sleeve 3, steel bushing sleeve 7 forms the labyrinth shape space with plastic bushing 4, in the labyrinth shape space sealant layer 8 is arranged, outer surface at steel bushing sleeve 7 and plastic bushing 4 has heat-contraction sleeve 9, at the two ends of heat-contraction sleeve 9 plexiglas cloth 10 is arranged, 11.Plastic bushing 4 inserts Steel Sleeves 3 and steel bushing and tucks inside the sleeve in the 7 formed annular spaces to form the labyrinth shape annular space.
The steel of steam line of the present utility model-mould sleeve joint, inorganic insulating layer 5 is inserted in termination at steel pipe 1 and steel pipe 2, and make steel pipe 1 and steel pipe 2 centerings, between inorganic insulating layer 5 and the Steel Sleeve 3 and the annular space between inorganic insulating layer 5 and the plastic bushing 4 inject organic heat-insulating layer 6, can be when construction with the organic heat-insulating layer 6 of Steel Sleeve 3 and plastic bushing 4 perforation injection foamings, the shutoff of will boring a hole then, at Steel Sleeve 3, steel bushing sleeve 7 injects sealant layer 8 with plastic bushing 4 formed labyrinth shape annular spaces, at sealant layer 8, the outer surface of steel bushing sleeve 7 and plastic bushing 4 coats heat-contraction sleeve 9, heating is shunk it then, makes plexiglas cloth 10 with the glass cloth winding of application of resin respectively at the two ends of heat-contraction sleeve 9,11.
The steel of steam line of the present utility model-mould sleeve joint to have the following advantages:
1, plastic bushing 4 is inserted Steel Sleeve 3 and steel bushing and tuck inside the sleeve 7 formed annular spaces, in the labyrinth shape space, insert sealant layer 8, will have utmost point excellent waterproof property, and have good expansion, shrinkage with formation labyrinth shape space.
2, heat-contraction sleeve 9 has excellent elasticity, can resist the pipe stress distortion.
3, applicable to the direct-buried steam pipeline of 150～320 ℃ of steam, 150～1020mm caliber.
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is steel-the mould sleeve joint sectional view of steam line of the present utility model.
Among the figure: the 1--steel pipe; The 2--steel pipe; The 3--Steel Sleeve; The 4--plastic bushing; The 5--inorganic insulating layer; 6--organic heat-insulating layer; 7--steel bushing sleeve; The 8--sealant layer; The 9--heat-contraction sleeve; 10--plexiglas cloth; 11--plexiglas cloth.
The steel of embodiment's 1 steam line-mould sleeve joint
Remove plastic bushing 4 and select glass reinforced plastic sleeve for use, sealant layer 8 selects for use pitch hemp cut, heat-contraction sleeve 9 to select for use polypropylene thermal shrink sleeve, plexiglas cloth 10,11 to select for use outside the glass cloth of polyurethane coating, and other is identical with embodiment 1.
