Abstract

The invention provides a fiber compensator. The fiber compensator comprises a skin, a stainless steel wire mesh, a heat preservation layer, a heat insulation padding layer, a rack and a baffle from inside to outside. The skin is fixed to the rack. The rack is made from a stainless steel or heat-resistant steel raw material. The heat preservation layer is selected from rock wool boards or rock wool seam blankets or ultra-fine glass fibers. The heat insulation padding layer is selected from rock wool or aluminum silicate fibers or quartz glass fibers. The skin comprises the layers of (1) silicone rubber glass fiber fabric cloth, (2) industrial canvas, (3) aluminum silicate glass fiber cloth, (4) asbestos cloth, (5) zirconium-containing glass fiber cloth and (6) wire glass fiber cloth from outside to inside. The fiber compensator has the technical effects of being not prone to abrasion and long in service life.

Description

technical field [0001] The invention relates to a fiber compensator and belongs to the technical field of machinery. Background technique [0002] Compensators are also customarily called expansion joints, or expansion joints. It consists of a bellows (an elastic element) that constitutes its main body and accessories such as end pipes, brackets, flanges, and conduits. Belongs to a compensation element. Utilize the effective expansion and contraction deformation of the bellows of its working body to absorb the dimensional changes of pipelines, conduits, containers, etc. caused by thermal expansion and contraction, or compensate the axial, lateral and angular displacement of pipelines, conduits, containers, etc. It can also be used for noise reduction and vibration reduction. It is widely used in modern industry. In heating, in order to prevent the pipe from being deformed or damaged due to thermal elongation or temperature stress when the heating pipe is heated up, it is...
