Abstract
The utility model is related to a kind of high-temperature metal expansion joints, including flange, bellows and pull rod, the both ends of the bellows are coaxially fixedly mounted with end pipe respectively, the outer end of two end pipes is fixedly mounted with flange respectively, end pipe inner wall close to bellows both ends is coaxially fixedly mounted with left ring flat-plate and right ring flat-plate respectively, the inboard of the left ring flat-plate is coaxially fixedly mounted with left inside lining, right ring flat-plate inboard below the corresponding left inside lining is coaxially fixedly mounted with right inside lining sleeve, the free end inner wall of the right inside lining sleeve is coaxially fixedly mounted with the first left ring flat-plate, and the steel wire of arcuate structure is installed between the first left ring flat-plate and the end of left ring flat-plate.This expansion joint realizes the multilayer insulation design to bellows by inside lining sleeve and ring flat-plate, and forms independent space to heat-preservation cotton again, prevents heat-preservation cotton to be pumped, to realize high temperature resistant, heat-insulated purpose.The utility model is designed reasonably is skillfully constructed, and heat-insulating property is high, and good airproof performance greatly improves the service life of expansion joint, the value with wide popularization and application.
Description
Technical field
The utility model belongs to the auxiliary device field of pipeline, specifically, especially a kind of high-temperature metal expansion joint.
Background technology
Expansion joint belongs to a kind of compensating element, using effective dilatation of its operative body bellows, with absorption line,
Change in size or compensation pipes that conduit, container etc. are generated by the reasons such as expanding with heat and contract with cold, conduit, container etc. it is axial, laterally
And angular displacement, it is widely used in modern industry.
When expansion joint is applied in hot environment, it is necessary to have heat safe ability, otherwise the medium in pipeline can influence
The service life of bellows.The poor and internal heat-preservation cotton of the heat insulation effect of traditional expansion joint is easily pumped, and significantly reduces expansion
The service life of section.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide it is a kind of it is simple in structure, prevent heat-preservation cotton from taking out
The high-temperature metal expansion joint walked.
What the embodiment of the utility model was realized in：
The both ends of a kind of high-temperature metal expansion joint, including flange, bellows and pull rod, the bellows are coaxial solid respectively
End pipe is filled, the outer end of two end pipes is fixedly mounted with flange respectively, and the outer rim of two end pipes is fixedly mounted with otic placode, pacifies between two otic placodes respectively
Pull rod is filled, the end pipe inner wall close to bellows both ends is coaxially fixedly mounted with left ring flat-plate and right ring flat-plate respectively, and the inboard of the left ring flat-plate is coaxial
Be fixedly mounted with left inside lining, the right ring flat-plate inboard below the corresponding left inside lining is coaxially fixedly mounted with right inside lining sleeve, the right inside lining sleeve with it is left inside
The free end inner wall of the interlaced overlapping in the opposite free end of lining, the right inside lining sleeve is coaxially fixedly mounted with the first left ring flat-plate, this first
The inner wall of the steel wire of installation arcuate structure between left ring flat-plate and the end of left ring flat-plate, the end pipe and right inside lining sleeve is fixedly mounted with more
Root palladium is followed closely, and palladium nail is for the castable refractory in fixed expansion section, the bellows and end pipe, left inside lining, right inside lining sleeve
Between fill heat-preservation cotton.
Moreover, the opposite exterior lateral sides of the flange install companion flange respectively, it is co-axially mounted between the companion flange and flange
Gasket.
The advantages of the utility model and good effect are：
This expansion joint realizes the multilayer insulation design to bellows by inside lining sleeve and ring flat-plate, and again to heat-preservation cotton shape
At independent space, heat-preservation cotton is prevented to be pumped, to realize high temperature resistant, heat-insulated purpose.The utility model design is closed
It manages, be skillfully constructed, heat-insulating property is high, and good airproof performance greatly improves the service life of expansion joint, has wide popularization and application
Value.
Description of the drawings
Fig. 1 is the sectional view of the utility model.
Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings and by specific embodiment.
A kind of high-temperature metal expansion joint, as shown in Figure 1, including flange 1, bellows 4 and pull rod 3, the bellows
Both ends are coaxially fixedly mounted with end pipe 2 respectively, and the outer end of two end pipes is fixedly mounted with flange respectively, and the outer rim of two end pipes is fixedly mounted with otic placode respectively
(non-label in figure) installs pull rod between two otic placodes.
The innovative point of the utility model is：
End pipe inner wall close to bellows both ends is coaxially fixedly mounted with left ring flat-plate 14 and right ring flat-plate 9 respectively, the inboard of the left ring flat-plate
It is coaxially fixedly mounted with left inside lining 11, the right ring flat-plate inboard below the corresponding left inside lining is coaxially fixedly mounted with right inside lining sleeve 10, the right liner
Cylinder is interlaced overlapping with the free end that left inside lining is opposite, and the free end inner wall of the right inside lining sleeve is coaxially fixedly mounted with the first left ring flat-plate
12, the steel wire 13 of arcuate structure is installed between the first left ring flat-plate and the end of left ring flat-plate, the end pipe and right inside lining sleeve
Inner wall is fixedly mounted with more palladium nails 6, and palladium nail is for the castable refractory 15 in fixed expansion section, the bellows and end pipe, a left side
Heat-preservation cotton 5 is filled between inside lining sleeve, right inside lining sleeve.By the setting of left and right inside lining sleeve and left and right ring flat-plate, steel wire, effectively rise
The problem of having arrived heat insulation, having prevented bellows from overheating and reducing the service life, and heat-preservation cotton is prevented to be pumped, improves product
Heat insulation effect.
In the present embodiment, the opposite exterior lateral sides of the flange install companion flange 7 respectively, same between the companion flange and flange
Axis installs gasket 8.
It is emphasized that embodiment described in the utility model is illustrative, without being restrictive, therefore this reality
It is every new according to this practicality by those skilled in the art with the novel embodiment including being not limited to described in specific implementation mode
The other embodiment that the technical solution of type obtains also belongs to the range of the utility model protection.
