Description
Technical field
It is especially a kind of that dual antifriction and the self sealss of disconnecting prevention structure are set the present invention relates to pipeline compensator technical field
Whirl compensator.
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.

The side of platform is provided with sphere bulge loop, is provided with first annular seal space, first annular seal space and sets between the annular boss and gland flange
There is airtight and watertight padding, the second annular seal space, the second annular seal space are set between the position limiting convex ring of the outer tube and the crimping for rotating core pipe
Inside it is provided with sealing ring.
As the preferred technical solution of the present invention, the airtight and watertight padding in the first annular seal space is that skeleton compound seal is filled out
Material, the filler is made up of becket with the non-metallic fillers for being wrapped in metal ring outer surface.
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, the sealing ring in second annular seal space is that section is circular metal
Ring.
As the preferred technical solution of the present invention, the outer tube is with casing flange and conical converging through solid forging
Finishing shaping afterwards.
As the preferred technical solution of the present invention, the end of the conical converging is outside one's consideration chamfering provided with 45.
As the preferred technical solution of the present invention, the annular end face of the gland flange towards first annular seal space is set to oblique
Flexible non-metallic airtight and watertight padding is set in face, first annular seal space.
As the preferred technical solution of the present invention, the angle between the inclined-plane and rotary core tube outer surface of the gland flange
For 45 degree of angles.
The beneficial effects of the invention are as follows:Relative to prior art, the invention has the characteristics that:
1st, the sphere bulge loop and casing limit bulge loop of rotary core pipe ring shape boss side surfaces shape after pipeline is passed through high-pressure medium
Into tension type end face seal, frictional force is small, good sealing effect, and facilitates compensating for the flexible operating of device.Rotate core pipe crimping
The second annular seal space is constituted between casing limit bulge loop, both can be used for placing metal slip formation end face seal, can play again
Anticreep is acted on, while forming twin-stage antifriction and release-resistant sealing structure.
2nd, the outer tube of compensator, casing flange and conical converging are through integration forging and drawing and forming, then carry out essence
Processing forms weldless overall structure, and bearing strength is big, ensure that the security that high pressure is used.
3rd, flexible non-metallic airtight and watertight padding can be both used in first annular seal space, skeleton compound seal filler can be also used,
The loss of airtight and watertight padding, which can be made, to be reduced, and strengthens sealing effectiveness.Slidable sealing copper ring is set in the second annular seal space, can not only be risen
To abrasion is reduced, the flexibility of compensator operating is improved, and forms Multi-level sealing structure, sealing effectiveness is further enhanced.
The present invention is applied to high pressure heat distribution pipe network, simple in construction, overall without welding, and bearing strength is big, without acceptance of persons,
Good seal performance, safe and reliable, life of product is long, is conducive to energy-conservation and environmental protection.
