Abstract
The invention discloses a fiber expansion joint with a strap protecting device and a novel depression bar. The fiber expansion joint comprises a strap, a heat-insulation layer, the depression bar, an upper connecting pipe, a lower connecting pipe, an upper annular plate, a lower annular plate, draw bars and the strap protecting device, fixing holes are arranged on the depression bar, the strap protecting device is fixed onto the surface of the strap by the depression bar, and the fixing holes are punched on the depression bar mechanically. A metal screen is fixedly mounted on the strap of the fiber expansion joint, can protect the strap of the fiber expansion joint when the fiber expansion joint is hoisted and transported, and prevents the strap from being abraded easily, the fixing holes are mechanically punched on the depression bar, labor can be greatly saved, and production efficiency is improved.
Description
Technical field
The present invention 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.Because filament expansion pitch circle band is generally made with rubber material, easy abrasion under the situation of repeatedly lifting transportation reduces its working life.And the punching of traditional press strip is to adopt the manpower punching, bothersome effort, inefficiency.
Summary of the invention
Technical problem to be solved by this invention is the deficiency to above-mentioned existing technology, and the filament expansion joint of a kind of zone circle band protective gear and novel press strip is provided.
For solving the problems of the technologies described above; The technological scheme that the present invention adopted is: the filament expansion joint of a kind of zone circle band protective gear and 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, and pull bar is fixedly connected with upper connecting tube, lower linking tube respectively through support; Upper ring plate is connected with the upper connecting tube vertical fixing; Lower ring plate is connected with the lower linking tube vertical fixing, and the upper end of lower linking tube is stretched in the upper connecting tube, and the fixed hole of some is arranged on the press strip; 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, also comprise the astragal protective gear, the astragal protective gear is fixed on the astragal surface by press strip; Fixed hole is got for the mode that adopts mechanical punching.
As the further improved technological scheme of the present invention, said astragal protective gear is wire netting or sheet metal.
As the further improved technological scheme of the present invention, said astragal protective gear is a wire netting.
As the further improved technological scheme of the present invention, said astragal protective gear is a steel wire.
As the further improved technological scheme of the present invention, said fixed hole be shaped as oblong.
As the further improved technological scheme of the present invention, the span between the said fixed hole is 5-10 centimetre.
As the further improved technological scheme of the present invention, the span between the said fixed hole is 8 centimetres.
The present invention installs the layer of metal net in the fixed outside of filament expansion pitch circle band, can in the process of lifting and transportation, protect filament expansion pitch circle band, makes it be difficult for being worn, thereby prolongs the working life of filament expansion pitch circle band; Method with mechanical punching is got fixed hole on press strip; Can practice thrift manpower greatly, enhance productivity, oblong fixed hole can 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.

Embodiment
Embodiment 1
Referring to Fig. 1, the filament expansion of this zone circle band protective gear and novel press strip joint 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; 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 10 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 10; 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 10, and the span between the fixed hole 10 is consistent; Be about 8 centimetres; Fixed hole 10 is an oblong, above than below bigger, be convenient to fix; Adopt the mode of mechanical punching to increase work efficiency, reduce labor strength; In astragal 1 mounted on surface steel wire 9 is arranged, chain link fence 9 is rolled in astragal 1 outside, and the edge is fixed up by press strip 3, and astragal 1 is not directly contacted with the outside, when lifting and transportation, is not worn, thereby prolongs its working life.
