Abstract
A high-temperature metal seal sleeve compensator comprises an outer sleeve, an inner sleeve and a pulling-out preventing flange, wherein a flange of the outer sleeve is connected with the pulling-out preventing flange through a bolt, the inner sleeve is inserted into the outer sleeve through an outer sleeve inserting hole in a front end cover of the outer sleeve, the outer wall of the inner sleeve is tightly matched with the outer sleeve inserting hole, the rear end of the inner sleeve is fixedly connected with a supporting ring, and the outer annular surface of the supporting ring is in sliding fit with the inner wall of the outer sleeve. The high-temperature metal seal sleeve compensator is reasonable in design and safe and reliable in work performance, service life is more than 20 years, and therefore a maintaining well which is specially arranged can be omitted, construction cost can be greatly lowered, and the high-temperature metal seal sleeve compensator can be used for conveying pipelines of city and town heating, metallurgy, electric generation, petrifaction, construction and other industries more conveniently.
Description
Technical field
The invention belongs to pressure piping element, be mainly used in compensating the axial stretching of pipeline and rotation radially.
Background technique
Because the 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 conventionally in pipeline.Because material filling type compensator needs regular replenishment filler, so also need special maintenance well is set, improved engineering cost under ground piping, increased maintenance cost; The stainless steel of corrugated expansion joint has aggravated corrosion because of chloride ion content in fed sheet of a media, thereby explosion occurs, and major accident easily occurs and cause a large amount of economic losses.
Summary of the invention
It is safe and reliable that object of the present invention is just to provide a kind of service behaviour, the high-temperature metal seal sleeve barrel compensator that long service life applicability is wide.The present invention is not only applicable to hot water pipe net and is applicable to steam pipe system.Made up the deficiency of compensator of straight-embedded socket.
The technological scheme adopting is:
A high-temperature metal seal sleeve barrel compensator, comprises outer sleeve, inner sleeve and prevents breaking flange, it is characterized in that:
Outer sleeve rear end is fixed with flange, the flange of outer sleeve is broken flange and is connected with anti-by bolt, the outer sleeve jack of inner sleeve from the front cover of outer sleeve is inserted in outer sleeve, inner sleeve jack on the outer wall of inner sleeve and outer sleeve front cover closely cooperates, to prevent that dirt from entering in outer sleeve, 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 slidably matched.
In the front inner wall of above-mentioned outer sleeve, be equiped with stainless steel metal seal ring, the two ends of this stainless steel metal seal ring are straightway, and middle part is 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 respectively a plurality of holes, can play pressure regulating action.
On the hole wall of above-mentioned outer sleeve jack, offer dustproof groove, in this dustproof groove, be equiped with dust-proof seal ring, sealing circle has further strengthened sealing and dustproof effect.
Major advantage of the present invention:
1. service behaviour is safe and reliable
The front portion of outer sleeve is welded with stainless steel metal seal ring and guarantees sealing reliability; On outer sleeve front end, be equiped with dust-proof seal ring, played the effect of anti-outside dirt; 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 present invention adopts metal sealing, thus Applicable temperature scope wide (can be used for-40 ℃~300 ℃) solved before the sleeve expansion joint of rubber seal can not be for the deficiency of steam pipe system.
3. reduced construction cost
Due to of the present invention 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 greatly reduce engineering cost, more easily for the conveyance conduit of the industries such as cities and towns heating, metallurgy, generating, petrochemical industry, building.
Accompanying drawing explanation
Fig. 1 is a kind of example structure schematic diagram of the present invention.
