Description
Technical field
The utility model relates to compensator, specifically a kind of sleeve expansion joint.
Background technique
Sleeve expansion joint claims tubular type telescopic joint, is the compensation device of hot fluid pipeline, is mainly used for after rectilinear duct additionally arranges
The axial thermal expansion of appearance is displaced absorption compensation, is a kind of to be directly installed on that any conveying is free from corrosion unidirectional or multidirectional fluid
Compensator among pipeline.Slip-type expansion joint is widely used in cities and towns heating, metallurgy, mine, power generation, petrochemical industry, building etc.
In the conveyance conduit of industry, since sleeve expansion joint working environment is severe, and the liquid of inside transport high-temperature, therefore sleeve
Outer wall be often subject to the interference of the impurity such as silt, cause the sliding of adapter tube and outer tube to have some setbacks, due to the principle expanded with heat and contract with cold,
Since adapter tube internal diameter is larger, biggish deflection can be axially being generated, and axial stress is also corresponding larger, it is existing
It takes over undesirable with the sealing effect of outer tube in technology, often has magazine infiltration, and when axial stress is larger, also without accordingly
The scheme that axial stress is changed to radial stress.
Summary of the invention
In order to solve the above technical problems, can have the purpose of the utility model is to provide a kind of big axial compensator of lateral type
Effect solves above-mentioned technical problem, and specific technical solution is as follows:
A kind of big axial compensator of lateral type is equipped with the first adapter tube, the fixed setting the at the end circumference of the first adapter tube
The other end of one flange, the first adapter tube is fixed on one end of bellows, in the second adapter tube of other end setting of bellows, second
The periphery of adapter tube is equipped with outer tube, and second flange is fixedly installed in the end of the outer tube, and differential is arranged in one end of second flange,
Bolt is screwed onto the screwed hole of centre of second flange and differential, is arranged sliding block between outer tube and the second adapter tube, sliding block it is recessed
Be equipped with polytetrafluoroethylene (PTFE) version in slot, be equipped with airtight and watertight padding in the side of sliding block, the airtight and watertight padding the second adapter tube and outer tube it
Between, the other end of outer tube is fixed on the outer wall of third adapter tube, and the third adapter tube is connect with bellows, the number of the bellows
Amount is two, is equipped with guide shell in the lower section of bellows, is fixed with first flange in the end of third adapter tube；
The sliding block quantity is two, is respectively fixedly disposed on the inner wall of outer tube and the outer wall of the second adapter tube, first connects
It manages consistent with the internal diameter of the second adapter tube.
The utility model has the advantages that: have radial compensation function, due to sliding block it is mutual abutting can make adapter tube with outside
The sealing effect of pipe more preferably, and makes a part of axial stress be transformed into radial stress, and then alleviate axial stress.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is partial enlarged view at the A of Fig. 1；
Specific embodiment
The utility model is illustrated with reference to the accompanying drawing, as shown in Figure 1 and Figure 2, a kind of big axial compensator of lateral type,
Equipped with the first adapter tube 2, first flange 1 is fixedly installed at the end circumference of the first adapter tube 2, the other end of the first adapter tube 2 is fixed
In one end of bellows 4, second adapter tube 6 is set in the other end of bellows 4, is equipped with outer tube in the periphery of the second adapter tube 6
12, second flange 8 is fixedly installed in the end of the outer tube 12, and differential 7 is arranged in one end of second flange 8, and bolt 9 is screwed onto second
In the screwed hole of centre of flange 8 and differential 7, sliding block 10 is set between outer tube 12 and the second adapter tube 6, is set in the groove of sliding block 10
There is polytetrafluoroethylene (PTFE) version 16, is equipped with airtight and watertight padding 15 in the side of sliding block 10, the airtight and watertight padding 15 is in the second adapter tube 12 and outside
Between pipe 6, the other end of outer tube 12 is fixed on the outer wall of third adapter tube 13, and the third adapter tube 13 is connect with bellows 4, institute
The quantity for stating bellows 4 is two, is equipped with guide shell 14 in the lower section of bellows 4, is fixed in the end of third adapter tube 13
First flange 1；
10 quantity of sliding block is two, is respectively fixedly disposed on the inner wall of outer tube 12 and the outer wall of the second adapter tube 6, the
One adapter tube 2 is consistent with the internal diameter of the second adapter tube 6.
The working principle of the utility model is: since hot and cold alternation converts so that nozzle inner wall generation heat expansion is cold in adapter tube
The phenomenon that contracting, when radially generating change in displacement, bellows can offset radial stress, and can undertake a part of radial change
Shape amount, and sliding can prevent axial displacement excessive when generating axial deflection, between the first adapter tube and outer tube, and in axial position
It moves in the case where generating, two sliding blocks can prevent adapter tube from falling off when mutually abutting against, the polytetrafluoroethylene (PTFE) being arranged in slip recess
The deflection that plate 16 can be born is bigger, so that sealing effect is more preferable.
