Description

Technical Field

[0001] The utility model relates to the field of pipeline connectors, and more specifically to a metal compensator for a reinforced circulating fluidized bed boiler. Background Art

[0002] Metal compensators are used to compensate for axial displacement, lateral displacement or combined axial and lateral displacement. They have the ability to compensate for angular displacement and generally have the ability to expand and contract. They can be used as connectors in circulating fluidized bed boiler pipelines.

[0003] During the use of the metal compensator for the circulating fluidized bed boiler, there is no supporting component underneath the metal compensator when it deforms left and right, and it is unable to share the operating pressure of the metal compensator, which causes the connection parts on the left and right sides to easily fall off, affecting the use efficiency of the metal compensator. Therefore, it is necessary to design a reinforced metal compensator for the circulating fluidized bed boiler to solve the above problems. Utility Model Content
