Into expanding with heat and contract with cold, the displacement of pipeline is typically compensated using telescopic compensator or whirl compensator.Slip expansion section
Because the displacement for compensating pipeline is stretched to compensate by sliding core pipe, 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 of.The structure of whirl compensator
Generally use bushing type, airtight and watertight padding chamber is provided between inner and outer pipes, and airtight and watertight padding is put into annular seal space, compressed by gland
Airtight and watertight padding seals to realize.
Existing whirl compensator generally there are problems with high temperature and high pressure environment：Between cooperation between rotary part
Gap is larger, and by pipeline thrust, the stability that inner and outer pipes rotate against is poor, is also easy to produce not coaxial eccentric deflection, increase rotation
Resistance, reduce the flexibility of rotation compensation.Prior art generally use steel ball controls the same of inner and outer pipes as rolling friction pair
Axle rotates, and its is complicated, and difficulty of processing is big.The bearing load of steel ball is smaller, for easily wearing or being pressed in pressure piping
It is bad, using the sealing property that airtight and watertight padding can be influenceed after a period of time, cause seal failure, leak.So that pipeline
Thermodynamic loss is produced, industrial accident even occurs, not only directly affects economic benefit, but also meeting generation environment is asked
Topic.
