Description
Technical field
This utility model is related to pipeline compensating sleeve technical field, especially relates to a kind of bellows seal sleeve and compensates
Device.
Background technology
Sleeve expansion joint of the prior art is generally sealed using filler, i.e. between inner sleeve and sealed letter
Space（Stuffing-box）Then packing is compacted between inner sleeve and sealed letter in stuffing-box by interior filling packing by gland
Sealed.During work, inner sleeve slides in stuffing-box and realizes the compensation of displacement.Due to sealant during using for reduction
（Filler packing）Abrasion leaks, and is provided with gap between filler packing, devises fluid injection in the relevant position of sealed letter body
Mouthful, once leaking, then can inject sealant from liquid injection port, thus forming lantern ring in the gap in filler packing, real
Now further seal.Use for many years shows, the sealing property of this sleeve expansion joint improves, but leakage is still
Unavoidably.
Utility model content
In order to solve above-mentioned technical problem, this utility model provides a kind of bellows seal sleeve barrel compensator.
This utility model be employed technical scheme comprise that to solve above-mentioned technical problem：A kind of bellows seal sleeve compensates
Device, including sealed letter, inner sleeve and gland, described sealed letter includes one end to be had the sealed letter body of tubular of outward flange and is located at
Support ring on wall in sealed letter body, inner sleeve is set in sealed letter body, and gland is located between inner sleeve and sealed letter body simultaneously
It is connected by bolt with the outward flange of sealed letter body, load in the space being formed between inner sleeve, sealed letter and gland
There is sealed bladder, sealed bladder is provided with for entering mouth to the intracapsular pressure medium being filled with pressure medium of sealing, on sealed letter body
It is provided with and enter, with pressure medium, the pressurization mouth that mouth cooperation is installed.
Further, described sealed bladder can be ring-type, the inner periphery of sealed bladder and excircle respectively with inner sleeve
The inwall of outer wall and sealed letter body matches and is sealed.
Can also, described sealed bladder is multiple, all curved, the sealed bladder of multiple arcs be sequentially arranged in inner sleeve,
One interrupted annular of formation in the space that sealed letter and gland are formed, be provided between two adjacent sealed bladders for every
Open the baffle plate of two sealed bladders.
Further, described sealed bladder is made using mild steel.
Further, described sealed bladder is made using polyurethane material.
Further, the one end not setting outward flange in sealed letter body is welded with the adapter of taper.
Beneficial effect：
This utility model has the ability automatically compensating after abrasion due to the elasticity of sealed bladder itself, such that it is able to realize
Whole sleeve expansion joint effective sealing in use is without leakage.
