Abstract
Description
technical field
[0001] The invention relates to a pipeline compensator, in particular to a spherical compensator. Background technique
[0002] Spherical compensators are often used in thermal pipelines, vaporization cooling devices of metallurgical equipment, and building pipelines. They mainly form a force couple through the rotation and bending of the ball head and the force arm, so that a pair of equal and opposite forces surround the central axis. Rotate to realize the absorption of pipeline expansion on both sides of the couple.
[0003] Patent No. 201120559664.3 "A Spherical Compensator" discloses a spherical compensator that installs a sealing ring on the radially outer side of the sphere. Due to the small contact area of the sealing ring, the load per unit area of the sealing ring is relatively large. Easily damaged, causing leakage.
[0004] Patent No. 200820300623.X "Rotary Joint" also discloses a structure of a spherical compensator, which uses an axial sph...
