QUICK-RELEASE COUPLING OF PRESSURE PIPES

摘要

A quick-release coupling of pressure pipes comprises pipes with flanges at the ends and tightening element tightened with a fixation element, this is placed in conical slot formed with inner conical surfaces of flanges and outer surface of the pipe. The tightening element is arranged as a trapezium with truncated angles of the base, and the truncation line is normal to bisector of the angle formed with lines of the outer surface of the lower part of the pipe and inner surface of the flange.
