Background technology
At present, during the high-temperature medium such as existing heat distribution pipe network conveying hot water, steam, because pipeline by medium temperature is influenceed shape
Into expanding with heat and contract with cold, the displacement of pipeline is typically compensated using telescopic compensator or whirl compensator.Slip expansion section
Displacement due to compensating pipeline is stretched to compensate by slip core pipe, and compensation ability is limited by structure, and slides core pipe
Sealing between filler can not persistently be maintained a good state, and leakage is easily produced after long-term use.The structure of whirl compensator
Generally use and airtight and watertight padding chamber is provided between bushing type, inner and outer pipes, airtight and watertight padding is put into annular seal space, compressed by gland
Sealing is realized in airtight and watertight padding.
Existing whirl compensator generally there are problems with high temperature and high pressure environment：Between cooperation between rotary part
Gap is larger, by pipeline thrust, and the stability that inner and outer pipes are rotated against is poor, is also easy to produce not coaxial eccentric deflection, increase rotation
Resistance, reduces the flexibility of rotation compensation.Prior art generally controls the same of inner and outer pipes as rolling friction pair using steel ball
Axle is rotated, and its is complicated, and difficulty of processing is big.The bearing load of steel ball is smaller, for easily wearing and tearing or being pressed in pressure piping
It is bad, using the sealing property of airtight and watertight padding can be influenceed after a period of time, cause seal failure, leak.So that pipeline
Produce thermodynamic loss.If it find that with maintenance not in time, or even industrial accident can be caused, not only directly affect economic effect
Benefit, but also can generation environment problem.

First annular seal space is provided between position limiting convex ring, the second annular seal space is provided between the position limiting convex ring and annular boss, first is close
Airtight and watertight padding is respectively equipped with envelope chamber and the second annular seal space.
As the preferred technical solution of the present invention, the rotary flange seat forms whole with constricted arc pipe through integrated forging
Body structure, the top of constricted arc pipe is provided with the straight flange end pipe of uniform internal diameter.
As the preferred technical solution of the present invention, the rotary flange seat inwall of the first annular seal space is provided with W shape bulge loops, makes
Obtain first annular seal space formation labyrinth seal chamber.
As the preferred technical solution of the present invention, the surface of the W shapes bulge loop is multiple continuous arc surfaces；Described first
Skeleton compound seal filler is provided with annular seal space, the filler is by becket and the non-metallic fillers structure for being wrapped in metal ring outer surface
Into.
As the preferred technical solution of the present invention, set between the becket and gland flange of the skeleton compound seal filler
There is butterfly spring.
As the preferred technical solution of the present invention, the end of the skeleton compound seal filler metal ring is set to circular arc end
Face.
As the preferred technical solution of the present invention, it is circular sliding ring that section is provided with second annular seal space,
Sliding ring is made up of metal material.
The beneficial effects of the invention are as follows：Relative to prior art, the invention has the characteristics that：1st, the rotary process of compensator
Blue seat and constricted arc pipe is overall structure through integration forging and drawing and forming, and solderless seam, bearing strength is big, ensure that
The security that high pressure is used.
2nd, first annular seal space is set to labyrinth shape structure, while using skeleton compound seal filler, can make airtight and watertight padding
Loss reduction, strengthens sealing effectiveness.Metal slide sealing ring is set in the second annular seal space, reduction abrasion can not only be played, improved
The flexibility of compensator operating, and Multi-level sealing structure is formed, sealing effectiveness is further enhanced, in the total life cycle of compensator
It inside need not almost change airtight and watertight padding.
3rd, compensator rotation pipe is identical with the internal diameter of rotary flange seat, and extra flow resistance is not produced, installs non-directional want
Ask.The present invention is applied to high pressure heat distribution pipe network, displacement compensation amount is larger, without acceptance of persons, good seal performance, safe and reliable, production
Product long lifespan.
