Abstract
The utility model relates to a kind of expansion joints, specifically for compensating the high-temperature expansion joint of high-temperature service or flue thermal expansion curve.It includes two connecting tubes, and the axis of two connecting tubes on the same line, and has gap between two connecting tubes.Its main feature is that there is the set between its annular flange circumferentially, the outer peripheral surface of two connecting tube annular flanges to be connected with expansion tube on the outer wall of two connecting tube abutting ends, expansion tube is made of elastic material；Ceramic fiber cotton circle is filled between the inner sidewall of two connecting tube annular flanges.The sealing effect of the high-temperature expansion joint is good, can avoid leakage cigarette, and manufacture and the difficulty installed are small.
Description
Technical field
The utility model relates to a kind of expansion joints, specifically for compensating the height of high-temperature service or flue thermal expansion curve
Warm expansion joint.
Background technique
Currently, traditional high-temperature expansion joint include two connecting tubes 1, the axis of two connecting tubes 1 on the same line, and
There is gap between two connecting tubes.Interpolation pipe 2 and outer tube 3 are arranged concentrically between two connecting tubes, interpolation pipe 2 passes through interior connecting plate
It is fixed therein on the inner peripheral surface of a connecting tube 1, outer tube 3 is fixed on the outer peripheral surface of a connecting tube 1 by outside link plate
On, between the gap of two connecting tubes, outer tube and not to be provided with annular between the outer peripheral surface of that connecting tube of outer tube close
Seal 4, as shown in Figure 1.During expansion, outer tube can move axially traditional high-temperature expansion joint with interpolation pipe, so that ring
Shape sealing ring displacement, causes sealing performance to decline, and leakage cigarette phenomenon easily occurs.Moreover, the structure of cannula type is being manufactured and was being installed
To the more demanding of precision in journey, manufacture and the difficulty installed are big.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of high-temperature expansion joint, the sealing effects of the high-temperature expansion joint
It is good, it can avoid leakage cigarette, manufacture and the difficulty installed are small.
To solve the above-mentioned problems, the following technical schemes are provided:
A kind of high-temperature expansion joint of the utility model includes two connecting tubes, and the axis of two connecting tubes is in same straight line
On, and have gap between two connecting tubes.Its main feature is that having on the outer wall of two connecting tube abutting ends along its ring circumferentially
Shape flange, set is connected with expansion tube between the outer peripheral surface of two connecting tube annular flanges, and expansion tube is made of elastic material；Two connections
Ceramic fiber cotton circle is filled between the inner sidewall of pipe annular flange.
Wherein, there are annular stiffening plate, the axis and connecting tube of annular stiffening plate on the inner sidewall of one of annular flange
Axis be overlapped.
Be connected on the outer peripheral surface of the annular flange is in the 90 annular flangings bent outward, on annular flanging
It is cased with annular pressing plate, the both ends of expansion tube are located between annular flanging and annular pressing plate, and annular flanging, annular pressure
Bolt hole is distributed along the circumference on the both ends of plate and expansion tube, running through in bolt hole has bolt, so that expansion tube is fixed on
Between two annular flanges.
The expansion tube is made of tetrafluoro covering.
The above scheme has the following advantages:
Due to having along it circumferentially on the outer wall of two connecting tube abutting ends of the high-temperature expansion joint of the utility model
Annular flange, set is connected with expansion tube, the inside of two connecting tube annular flanges between the outer peripheral surface of two connecting tube annular flanges
Ceramic fiber cotton circle is filled between wall.This high-temperature expansion joint covers directly between two connecting tubes to be connected by elastic material expansion tube,
During expansion, it is expanded using the flexible completion of expansion tube, expansion tube can further compress annular flange when flexible, therefore swollen
When swollen, sealing effect still can guarantee, so as to avoid the generation of leakage cigarette phenomenon.Moreover, higher without manufacture and installation accuracy
Intubation, thus greatly reduces the difficulty of manufacture and installation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of background technique；
Fig. 2 is the structural schematic diagram of the high-temperature expansion joint of the utility model.
Specific embodiment
The utility model is described in further details below in conjunction with attached drawing.
As shown in Fig. 2, a kind of high-temperature expansion joint of the utility model includes two connecting tubes 1, the axis of two connecting tubes 1
On the same line, and between two connecting tubes 1 there is gap.Its main feature is that having on the outer wall of two 1 abutting ends of connecting tube along it
Annular flange 2 circumferentially, set is connected with expansion tube 6 between the outer peripheral surface of two 1 annular flanges 2 of connecting tube, and expansion tube 6 is by elasticity
Material is made；Ceramic fiber cotton circle 7 is filled between the inner sidewall of two 1 annular flanges 2 of connecting tube.One of annular flange 2
Inner sidewall on have annular stiffening plate 8, the axis of annular stiffening plate 8 is overlapped with the axis of connecting tube 1.The annular flange 2
It is connected with the annular flanging 3 bent outward in 90 on outer peripheral surface, is cased with annular pressing plate 4 on annular flanging 3, expands
The both ends of pipe 6 are located between annular flanging 3 and annular pressing plate 4, and annular flanging 3, annular pressing plate 4 and expansion tube 6
Bolt hole is distributed along the circumference on both ends, running through in bolt hole has bolt 5, so that expansion tube 6 is fixed on two loop methods
Between orchid 2.The expansion tube 6 is made of tetrafluoro covering.
This high-temperature expansion joint is covered even directly between two connecting tubes 1 by elastic material expansion tube 6, during expansion, is utilized
The flexible completion of expansion tube 6 expands, and expansion tube 6 can further compress annular flange 2 when flexible, therefore during expansion, still may be used
Guarantee sealing effect, so as to avoid the generation of leakage cigarette phenomenon.Moreover, without manufacture and the higher intubation of installation accuracy, thus
Greatly reduce the difficulty of manufacture and installation.
