DEVICE FOR CONNECTION BETWEEN ADJACENT SOLAR RECEIVER TUBES

摘要

Device for connection between adjacent solar receiver tubes of the type which are at the end of the solar receiver tube (1) to be joined with another adjacent solar collector tube, comprising:
- An expansion compensating element with at least two concentric bellows (7, 8) that are connected to each other and to a rigid ring (9) by means of a welded joint, which keeps them concentric in the expansion and compression process and joined to the glass tube (4) by the cover (12) and glass- metal transition element (21),
- A connection flange (5) to connect the solar receiver tube (1) to the one adjacent thereto, the flange (5) being a round metal plate with a hole that houses the absorber tube (3),
- Some through bolts (20) passing through the connection flange (5) to attach it with flange of the adjacent receiving tube (1).
