Flange connection has flanges, outer surfaces, end surfaces, stepped surfaces, shoulders, sleeve, holes, groove, and sealing rings

摘要

The flange connection has a first (8) and second (9) flange with a first (11) and second (15) cylindrical outer surface, a first (12) and second (16) end surface and a first (13) and second (17) cylindrical stepped surface starting from the first and second end surfaces respectively and with relatively reduced diameter and ending in a first (14) and second (18) shoulder. The two flanges are axially connected by connections. A covering sleeve (20) is contained , with its cylindrical hole (21), in an annular groove (19) formed by the two stepped surfaces and two shoulders. The ends have conically widening holes (22,23). Sealing rings (26,27) are contained in the space between the walls of the conical hole, the stepped surfaces and shoulders.
