Description
Technical field
The utility model is related to a kind of displacement compensation device more particularly to a kind of bellows heat using butterfly spring assembly
Power bit shift compensation holder.
Background technology
In industries such as electric power, petrochemical industry, chemical industry, bellows is necessary design part in hot working fluid transmission process, for into
The thermal expansion of row conveying pipe compensates, since when interval transports heat medium, bellows often produces in most cases
The raw displacement to a side, the displacement of bellows, which will be followed by, to be transported or stops to carry out when heat medium transmission to expand or receive accordingly
Contracting, this process can lead to the friction between bellows and fixing bracket support, this is that many reaction vessel ripple tube lifetimes are not long
Reason.The compensation holder of existing bellows includes being fixed on the existing bellows gasket of bellows to have complete sliding structure,
But it is passive type structure, and it can be by some restrictions in terms of use with stress, holder, pressure if there is active structure
The possibility of leakage is had when being varied from stress.
This application involves the bellows heating power bit shift compensation holders using butterfly spring assembly, propose a kind of bellows heating power position
Move Active Compensation holder.
Utility model content
The technical problems to be solved in the utility model is：A kind of bellows heating power bit shift compensation branch based on butterfly spring is provided
Frame can often generate thermal walking when the variation of bellows heating power transport temperature is frequent, and by compensating holder to temperature change
Displacement carries out Active Compensation.In particular for the thermal compensation of the heat supplies heat distribution pipeline such as existing power plant, chemical industry, food.
Scheme is used by order to overcome the deficiencies in the prior art, the utility model to solve technical problem：Base
In the 1 heating power bit shift compensation holder of bellows of butterfly spring, including supporting plate 2, active column 4 and vertical columns 8, nut 3, transverse bar 7,
Butterfly spring assembly 5, ground slots 6, the bellows 1 being connect with thermal pipe are placed in 2 plane of supporting plate, the bottom end bearing of vertical columns 8
Slided in ground slots 6, the lower section of supporting plate 2 installation transverse bar 7 and with the concatenated butterfly spring assembly 5 of transverse bar, transverse bar 7 and butterfly spring
Piece component 5 is installed and parallel with bellows between active column 4 and vertical columns 8, and one end of transverse bar 7 and vertical columns are solid
Fixed, the second end of transverse bar 7 passes through the hole of active column 4, nut 3 to be fixed on 7 second end end of transverse bar；Active column 4
Bottom end be supported in ground slots 6 and slide；The two supports of supporting plate 2 in the upper end of active column 4 and vertical columns 8, supporting plate 2
One end and the upper end of active column 4 are fixed, and 2 other end of supporting plate is slided in fixed movable upper end.
When butterfly spring piece or 2 lower part of butterfly spring assembly supporting plate are heated with bellows 1, butterfly spring piece or the expansion of butterfly spring piece drive and live
Dynamic column 4 and supporting plate displacement, it is identical as the direction of displacement of bellows, bellows heating power displacement is compensated, when bellows stops heat supply,
Butterfly spring piece or butterfly spring piece contract on cooling, tab (s) spring are cooled reinstatement, and compensation bellows heating power displacement disappears.
Advantageous effect：The utility model is connected in butterfly spring piece or butterfly spring piece component in transverse bar 7, be heated when butterfly spring piece or
Butterfly spring piece expand and transverse bar 7 to both ends expand, compensation compensation bellows heating power displacement, when contract on cooling, tab (s) spring by
Cold recovery original state.Solve the problems, such as that the effective hard supporting plate of ripple is easily worn using the utility model.In particular for larger
With the bellows of thicker diameter.
