Abstract
The utility model discloses a fiber expansion joint with novel depression bars. The fiber expansion joint comprises round belts, insulation layers, depression bars, an upper connecting pipe, a lower connecting pipe, an upper annular plate, a lower annular plate and a draw bar, wherein the draw bar is fixedly connected with the upper connecting pipe and the lower connecting pipe respectively through a holder; the upper annular plate is vertically and fixedly connected with the upper connecting pipe; the lower annular plate is vertically and fixedly connected with the lower connecting pipe; the upper end of the lower connecting pipe extends into the upper connecting pipe; a certain number of fixing holes are formed in the depression bars; both edges of each round belt are fixed on the upper annular plate and the lower annular plate respectively through the depression bars; insulation layers are formed among the upper connecting pipe, the lower connecting pipe, the upper annular plate, the lower annular plate and the round belts; and the fixing holes on the depression bars are long ellipses. Different from the traditional round fixing holes fixed at only one point, the fiber expansion joint provided by the utility model adopts the long elliptical fixing holes, thereby enabling more fixing spaces to be selected during installation, and improving the installation efficiency.
Description
Technical field
The utility model relates to a kind of expansion joint, particularly a kind of filament expansion joint.
Background technique
Expansion joint is the additional stress that causes because of temperature difference and mechanical vibration in order to compensate, and is arranged on a kind of flexible structure on container shell or the pipeline.Because it is as a kind of elastic compensating element that can freely stretch, advantages such as reliable operation, functional, compact structure have been widely used in departments such as chemical industry, metallurgy, nuclear energy.The filament expansion joint can provide bigger multidirectional compensation rate on less axial mounting distance, can effectively eliminate the installation integrating error of whole system simultaneously, than traditional expansion of metal joint the better application prospect is arranged.Filament expansion pitch circle band covers outside the thermal insulation layer, and main effect is to bear flue gas system pressure and from flue gas and extraneous chemical corrosion, protect thermal insulation layer.Press strip is used for astragal is fixed on the thermal insulation layer outside.Press strip realizes through fixed hole that fixedly traditional press strip fixed hole is circular, and nail is aimed at the center of circle and could be fixed, and efficient is lower.
The model utility content
The utility model technical problem to be solved is the deficiency to above-mentioned existing technology, and a kind of filament expansion joint with press strip that can quick mounting is provided.
For solving the problems of the technologies described above; The technological scheme that the utility model adopted is: a kind of filament expansion joint with novel press strip; Comprise astragal, thermal insulation layer, press strip, upper connecting tube, lower linking tube, upper ring plate, lower ring plate and pull bar, pull bar is fixedly connected with upper connecting tube, lower linking tube respectively through support, and upper ring plate is connected with the upper connecting tube vertical fixing; Lower ring plate is connected with the lower linking tube vertical fixing; The upper end of lower linking tube is stretched in the upper connecting tube, and at least two fixed holes are arranged on the press strip, and press strip is separately fixed at the astragal both sides on upper ring plate and the lower ring plate through fixed hole; Be thermal insulation layer between upper connecting tube, lower linking tube, upper ring plate, lower ring plate and the astragal, fixed hole is shaped as oblong on the press strip.
As the further improved technological scheme of the utility model, the span between the said fixed hole is 5-10 centimetre.
As the further improved technological scheme of the utility model, the span between the said fixed hole is 8 centimetres.
The utility model adopts oblong fixed hole let has more fixed space to select when installing, rather than as traditional circular fixed hole, can only be fixed on a point, can improve installation efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of the fixed hole of the utility model.
Further specify below in conjunction with the embodiment of accompanying drawing the utility model.
Embodiment
Embodiment 1
Referring to Fig. 1 and Fig. 2, this comprises astragal 1, thermal insulation layer 2, press strip 3, upper connecting tube 4, lower linking tube 5, upper ring plate 6, lower ring plate 7 and pull bar 8 with the filament expansion joint of novel press strip; Pull bar 8 is fixedly connected with upper connecting tube 4, lower linking tube 5 respectively through support, and upper ring plate 6 is connected with upper connecting tube 4 vertical fixing, and lower ring plate 7 is connected with lower linking tube 5 vertical fixing; The upper end of lower linking tube 5 is stretched in the upper connecting tube 4, and the fixed hole 9 of some is arranged on the press strip 3, and press strip 3 is separately fixed at astragal 1 both sides on upper ring plate 6 and the lower ring plate 7 through fixed hole 9; Connect mutually between upper connecting tube 4, lower linking tube 5, upper ring plate 6, lower ring plate 7 and the astragal 1, cavity of middle formation is filled with filler in the cavity; This filling space is thermal insulation layer 2, adopts the method for mechanical punching on press strip 3, to get fixed hole 9, and the span between the fixed hole 9 is consistent; Be about 8 centimetres, fixed hole 9 is an oblong, above than below bigger; Be convenient to fix, adopt the mode of mechanical punching to increase work efficiency, reduce labor strength.
