Beschreibung
Zusammenfassung:	The utility model belongs to the field of expansion compensation devices for pipelines, and discloses a rubber ball compensator which comprises a first guide cylinder, a second guide cylinder, a first aerogel felt layer, a first ceramic fiber felt layer, a second ceramic fiber felt layer, a second aerogel felt layer, a heat insulation material and a rubber layer, and the middle of the rubber layer protrudes outwards to form a hemisphere. The first aerogel felt layer, the first ceramic fiber felt layer, the second ceramic fiber felt layer, the second aerogel felt layer and the heat insulation material are utilized to form four heat insulation layers, heat transfer is effectively weakened, heat damage to the rubber layer is reduced, and the elasticity of the first aerogel felt layer is utilized, so that the heat insulation performance of the rubber layer is improved. The first flow guide cylinder and the second flow guide cylinder are both tightly attached to the first aerogel felt layer, the mass of a medium f
