Abstract
The invention discloses a totally-sealed fiber expansion joint with a novel trim strip. The totally-sealed fiber expansion joint comprises a ring belt, a heat-preservation layer, the trim strip, an upper connecting pipe, a lower connecting pipe, an upper annular plate, a lower annular plate and a pull rod, wherein at least two fixing holes are formed in the trim strip; the two sides of the ring belt are fixed on the upper and lower annular plates in a sealing way through the fixing holes by the trim strip respectively; the heat-preservation layer is arranged between every two of the upper connecting pipe, the lower connecting pipe, the upper annular plate, the lower annular plate and the ring belt; and the fixing holes are punched in a mechanical punching way. The fixing holes are punched in the trim strip in the mechanical punching way, so that manpower is greatly saved, and production efficiency can be improved; due to the oblong fixing holes, large fixing spaces can be selected in mounting rather than fixed points of the conventional circular fixing holes, so that mounting efficiency can be improved; and the internal heat-preservation layer can be well protected by the total-sealing ring belt, and prevents the heat-preservation layer from chemical corrosion from outside and in a pipeline, so that the service life of the fiber expansion joint is prolonged.
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.Traditional filament expansion pitch circle band is open type often, when the big pipeline of inleakage uses, can lower blast like this, but because seal, cause the corrosion of base insulating layer easily, the working life of reduction expansion joint.Press strip is used for astragal is fixed on the thermal insulation layer outside.Traditional press strip punching 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 a kind of band punching press strip fast is provided, and is adapted at the all-sealed filament expansion joint that the little pipeline of inleakage uses.
For solving the problems of the technologies described above; The technological scheme that the present invention adopted is: a kind of all-sealed 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 hole is arranged on the press strip, and press strip is distinguished sealing and fixing through fixed hole on upper ring plate and lower ring plate with the astragal both sides; Be thermal insulation layer between upper connecting tube, lower linking tube, upper ring plate, lower ring plate and the astragal, said fixed hole is got for the mode that adopts mechanical punching.
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.
As the further improved technological scheme of the present invention, said astragal material is that ethylene propylene diene rubber applies glass cloth.
The present invention gets fixed hole with the method for mechanical punching 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.And the all-sealed thermal insulation layer outside that is wrapped in of astragal is applicable to the pipeline that inleakage is little, compares the open type astragal and has the thermal insulation layer that can better protect inside, makes it avoid prolonging the working life of filament expansion joint from the chemical corrosion in outside and the pipeline; It is soft that the ethylene propylene diene rubber of selecting for use applies glass cloth performance, can absorb the displacement amount from each side.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of fixed hole of the present invention.
Further specify below in conjunction with the accompanying drawing specific embodiments of the invention.
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 all-sealed 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 at least two fixed hole 9 is arranged on the press strip 3, and press strip 3 is fixed on upper ring plate 6 and the lower ring plate 7 astragal 1 both sides are hermetically sealed respectively through fixed hole 9; Be that press strip 3 is tightly connected with upper ring plate 6 and lower ring plate 7, 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; Be 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; Span between the fixed hole 9 is consistent, is about 8 centimetres, and 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.All-sealed astragal is compared the open type astragal and is had the thermal insulation layer that can better protect inside, makes it avoid prolonging the working life of filament expansion joint from the chemical corrosion in outside and the pipeline; It is soft that the ethylene propylene diene rubber of selecting for use applies glass cloth performance, can absorb the displacement amount from each side.
