VALVING DEVICE FOR PIPE LINES Russian patent published in 1997 - IPC

Abstract RU 2100685 C1

FIELD: pipe line engineering. SUBSTANCE: valving device has flanges interconnected through an axial rod. Between the flanges is a ring conical clutch made of a rigid material and interacting with a clutch made of a flexible material. In the clutch made of a rigid material is a radial cut, and portions adjacent to the cut are movably interconnected so that in free position the diameter of the clutch is less than the inner diameter of the pipe line. EFFECT: enhanced reliability. 4 cl, 6 dwg
