The filler is arranged between the large section of the reducing pipe and the sleeving section of the inner pipe, the annular plate is connected with a large-section pipe orifice of the reducing pipe in a sealing manner, an inner hole of the annular plate is in clearance fit with the outer wall of the inner pipe so as to form a compensation structure that the corrugated pipe which is linked with the reducing pipe moves along the axial direction of the outer wall of the inner pipe. The single-pipe corrugated compensator is simple in axial structure, free to stretch, large in compensation quantity and long in service life.
Description
Technical field
The utility model relates to a kind of pipe safety device, and specifically, the utility model relates to a kind of single tube FlexbleJoint of slim-lined construction.
Background technique
Carbon black manufacturing industry is special because of operating mode, and the boiler specification configuring is generally very large, and the heat transferring medium of use is 700 DEG C of left and right, and with the high-temperature heat-exchanging bore of boiler matching more than 2000mm, more than the super 10000mm of length.The also corresponding length of heat exchanging tube of this kind of slim-lined construction high-temperature heat-exchanging configuration, due to overlength heat exchanging tube with high temperature media heat transfer process in produce larger distortion, wherein axial deflection maximum, heat exchanging tube axial deformation must bring larger end thrust or axial displacement.Tubular heat exchanger is made up of the identical heat exchanging tube side by side of gang's caliber, in heat transfer process, the end thrust of every heat exchanging tube generation is all towards a direction, integrated end thrust heat exchanger forms great impact, easily causes the even heat exchanger explosive accident of ftractureing of heat exchanger end plate.In engineering, for fear of there is this type of accident, conventionally, at the equipped compensator that can make nose balance of heat exchanging tube end, absorb axial displacement with this.Although prior art compensator have a lot of structural types, because of the reason such as nose balance amount is relatively little, axial stiffness is large and heatproof is inadequate, be all not suitable for carbon black manufacturing industry directly supporting.
Model utility content
The utility model, mainly for the deficiencies in the prior art, proposes one simple and reasonable for structure, and axial stiffness is little, compensation rate is large and resistant to elevated temperatures single tube FlexbleJoint.
The utility model is achieved through the following technical solutions technical goal.
Single tube FlexbleJoint, it is made up of jointly inner tube, adapter, bellows, thermal-protective coating, reducer pipe, filler and ring flat-plate.Described bellows and inner tube concentric gap are nested, the reducer pipe being set with on inner tube right-hand member outer wall is tightly connected with smaller diameter end and bellows right-hand member, the adapter being set with on inner tube left end outer wall is tightly connected with right-hand member and bellows left end, and the other end of adapter and inner tube mouth of pipe outer wall are tightly connected.Its improvements are: described inner tube bore is 89mm～159mm, and the elongated straight tube of the super 800mm of length is separated by and is formed the protection structure to bellows by thermal-protective coating between inner tube and bellows fit section.Described reducer pipe enlarged diameter section is cylindrical tube, plug filling material between cylindrical tube and inner tube shrinking section, ring flat-plate and the reducer pipe major diameter mouth of pipe are tightly connected, and ring flat-plate endoporus and outer wall of inner tube Spielpassung form the collocation structure of bellows interlock reducer pipe along outer wall of inner tube axial motion.
In said structure, thermal-protective coating is to be woven into blanket shape with alumina-silicate ceramic fibre to be wrapped on outer wall of inner tube, and filler is to be woven into rope form with alumina-silicate ceramic fibre to be entangled in reducer pipe inner chamber, bellows moulding with 2～3 layers of common rolling of thin plate.
The utility model compared with prior art, has following good effect:
1, axially fit linkage structure is simple, makes easily;
2, flexible bellows-sheathed is contained in rigidity inner tube, and capable of expansion and contraction, compensation rate is large;
3, between inner tube and bellows, be separated by with thermal-protective material, avoid bellows to cross thermal run away;
4, not pressure-bearing of bellows, only does axial elasticity distortion, uses safety, and the life-span is long.
Brief description of the drawings
Fig. 1 is the utility model structural profile schematic diagram.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
The FlexbleJoint of single tube shown in Fig. 1, it is made up of jointly inner tube 1, adapter 2, bellows 3, thermal-protective coating 4, reducer pipe 5, filler 6 and ring flat-plate 7.Described bellows 3 is to form flexible pipe with the common rolling of multilayer sheet with equal thickness, in the present embodiment, makes bellows 3 with 3 layers of sheet with equal thickness.Inner tube 1 is steel pipe, and bellows 3 is nested with inner tube 1 concentric gap.The reducer pipe 5 being set with on inner tube 1 right-hand member outer wall is tightly connected with smaller diameter end and bellows 3, and the adapter 2 being set with on inner tube 1 left end outer wall is tightly connected with right-hand member and bellows 3, and the other end and inner tube 1 mouth of pipe outer wall of adapter 2 are tightly connected.Inner tube 1 bore in the present embodiment is 101.3mm; the slender pipe of long 11000mm; between inner tube 1 and bellows 3 shrinking sections, be separated by by thermal-protective coating 4; thermal-protective coating 4 is that one alumina-silicate ceramic fibre is woven into blanket shape; outer being rolled on inner tube 1 outer wall of thermal-protective coating 4 forms the protection structure to bellows 3, avoids bellows 3 to cross thermal run away.Described reducer pipe 5 enlarged diameter sections are cylindrical tube, plug filling material 6 between cylindrical tube and inner tube 1 shrinking section.Filler 6 use alumina-silicate ceramic fibres in the present embodiment are woven into rope form, then be entangled in reducer pipe 5 inner chambers, in order to prevent that filler 6 scatters and disappears, at reducer pipe 5 major diameter mouth of pipe place welding ring flat-plates 7, ring flat-plate 7 endoporus and inner tube 1 outer wall Spielpassung, this linkage structure realizes bellows 3 collocation structure of reducer pipe 5 along inner tube 1 outer wall axial motion that link.When actual use, inner tube 1 right-hand member and heat exchanging tube are tightly connected, and reducer pipe 5 major diameter outer ends are sleeved in heat exchanger tube sheet and are welded to connect.In the time that heat exchanger is subject to heat transferring medium temperature difference influence, the axial displacement producing links reducer pipe 5 and bellows 3 along inner tube 1 outer wall axial motion by tube sheet, and this axial motion is capable of expansion and contraction, and compensation rate is large, in the present embodiment, axially compensation rate reaches 800mm, exceeds 4 times than prior art.In addition, not pressure-bearing of bellows 3 in the utility model, only does axial elasticity distortion, so use safety, life-span long.
