Abstract
The utility model provides a compensator for a high-temperature metal sealing sleeve. The compensator comprises an outer sleeve, an inner sleeve and an anti-snapping flange; a flange of the outer sleeve is connected with the anti-snapping flange through a bolt; the inner sleeve is inserted into the outer sleeve from an inserting hole of the outer sleeve on a front end cover of the outer sleeve; the outer wall of the inner sleeve is tightly matched with an inserting hole of the outer sleeve; a supporting ring is fixedly connected with the back end of the inner sleeve; and the outer ring face of the supporting ring is slidably matched with the inner wall of the outer sleeve. The compensator for the high-temperature metal sealing sleeve provided by the utility model has the advantages of reasonable design, and safe and reliable working property; furthermore, the service life is up to 20 years, so that a maintenance well can be prevented from being specially arranged; the engineering manufacturing cost can be greatly reduced; and the compensator is more conveniently used for transmission pipelines in industries of country heating, metallurgy, generation, petrifaction, building and the like.
Description
Technical field
The utility model belongs to the pressure piping element, is mainly used in the axial stretching of compensation pipeline and rotation radially.
Background technique
Because factors such as the difference variation of working medium and alignment error have caused pipeline axial flexible and radially reverse, flexible and radially reverse for eliminating pipeline axial, material filling type compensator or corrugated expansion joint are installed in pipeline usually.Because the material filling type compensator needs the regular replenishment filler, so special maintenance well also need be set under ground piping, has improved engineering cost, has increased maintenance cost; The stainless steel of corrugated expansion joint has aggravated corrosion because of chloride ion content in the fed sheet of a media, thereby explosion takes place, and is prone to take place major accident and causes a large amount of economic losses.
The model utility content
It is safe and reliable that the purpose of the utility model just provides a kind of service behaviour, the high-temperature metal seal sleeve compensator that the long service life applicability is wide.The utility model is not only applicable to hot water pipe net and is applicable to steam pipe system.Remedied the deficiency of direct-burried sleeve expansion joint.
The technological scheme that adopts is:
A kind of high-temperature metal seal sleeve compensator comprises outer sleeve, inner sleeve and anti-ly breaks flange, it is characterized in that:
The outer sleeve rear end is fixed with flange; The flange of outer sleeve is broken flange and is connected with anti-through bolt; Inner sleeve is inserted in the outer sleeve from the outer sleeve jack on the front cover of outer sleeve, and the inner sleeve jack on the outer wall of inner sleeve and the outer sleeve front cover closely cooperates, and gets in the outer sleeve to prevent dirt; The rear end of inner sleeve is fixedly connected with support ring, and the outer ring surface of this support ring and outer sleeve inwall are slidingly matched.
Be equiped with the stainless steel metal seal ring on the front inner wall of above-mentioned outer sleeve, the two ends of this stainless steel metal seal ring are straightway, and the middle part is a bellows segment; The outer wall interference fit of the bellows segment of stainless steel metal seal ring and inner sleeve plays good sealing effect, guarantees the reliability of sealing; The two ends straightway of stainless steel sealing ring offers a plurality of holes respectively, can play the pressure regulating action.
Offer dustproof groove on the hole wall of above-mentioned outer sleeve jack, be equiped with dust-proof seal ring in this dustproof groove, the sealing circle has further strengthened the sealing and dustproof effect.
The major advantage of the utility model:
1. service behaviour is safe and reliable
The front portion of outer sleeve is welded with the stainless steel metal seal ring and guarantees sealing reliability; Be equiped with dust-proof seal ring on the outer sleeve front end, played the effect of anti-outside dirt; The outer sleeve flange combination prevents that breaking flange has prevented that inner sleeve from pulling out, and guaranteed safety.
2. applicability is wide
Because the utility model adopts metallic seal, so Applicable temperature scope wide (can be used for-40 ℃～300 ℃) has solved the deficiency that the sleeve expansion joint of rubber seal before can not be used for steam pipe system.
3. reduced construction cost
Because the utility model is reasonable in design; Service behaviour is safe and reliable, and reaches working life more than 20 years, therefore can remove the maintenance well of special setting from; Can reduce engineering cost greatly, be used for the conveyance conduit of industries such as cities and towns heating, metallurgy, generating, petrochemical industry, building more easily.
Description of drawings
Fig. 1 is a kind of example structure schematic representation of the utility model.
Embodiment
A kind of high-temperature metal seal sleeve compensator comprises outer sleeve 1, inner sleeve 3 and anti-ly breaks flange 2, it is characterized in that:
