Abstract
The utility model provides a sleeve compensator. The sleeve compensator does not leak in use during a long buried period, even if leakage occurs, leakage amount is reduced to the greatest extent, and harm is reduced. The sleeve compensator is improved in structure. An O-shaped seal ring is arranged between an inner sleeve and a packing gland of a traditional sleeve compensator, and therefore sealing is improved, a safety factor is improved, sundries can be prevented from entering a packing seal position, and service life of a packing seal is prolonged. Meanwhile, another O-shaped seal ring is arranged between the packing gland and a packing box, and protection after the packing seal is leaked is improved.
Description
Technical field
The utility model relates to the sleeve expansion joint that uses in the fluid-transporting tubing.
Background technique
The sleeve expansion joint Applicative time is more of a specified duration, and application is extensive.The sleeve expansion joint Main Problems is to be difficult to the long-time use of assurance do not leak, in case occur leaking, affects pipeline and normally moves.
Summary of the invention
Do not leak for guaranteeing that sleeve expansion joint buries to use over a long time, even occur revealing, its leakage rate is reduced as far as possible, harm reduction, the utility model provides a kind of sleeve expansion joint that improves structure.
Between the inner core of conventional sleeve compensator and Gland, add an O type circle sealing, not only increased by a cover sealing, improved safety coefficient, can prevent that also foreign material from entering packing seal place, improve gland sealed working life.
Between Gland and packing case, also add simultaneously an O type circle sealing, increased the protection after packing seal is revealed.
