Rapid closure connection for e.g. discharge piping of pump installation, has segments including inner surfaces with grooves whose walls are beveled to form angle equal to sum of total angle formed by conical surfaces and specific angle

摘要

The connection has a clamping collar (1) including a flexible separated band (11) with ends arranged to fix clamping bolts, and sleeves (2) including cylindrical outer peripheral surfaces (22) with tooth-shaped recesses (221) whose bases are provided with a peripheral end grooving (222). Separated circular segments (13) have peripheral inner surfaces provided with peripheral grooves whose lateral walls are beveled by centering to form an angle equal to sum of total angle (beta) formed by rear conical surfaces (214) of sleeves` flanges (21) and a specific angle ranging from 3 to 4 degrees.
