BARREL FOR A CONTROL VALVE WITH PACKING-GLAND RETAINING RING COMPRISING A CENTRAL HORIZONTAL STEM

摘要

A barrel for a control valve (10) for a fluid circulation circuit, said barrel being configured to be rotatable around an axis (A) and comprising a packing gland (30) in the shape of an angular portion of a cylindrical sleeve, capable of occupying at least two angular positions in order to open or close the lateral holes of the valve as a function of the angular position of the barrel to permit or interrupt the distribution of the fluid through said lateral holes, the barrel further comprising a retaining ring (40) capable of exerting a transverse elastic returning force enabling the free ends (41, 43) of the packing gland (30) to be moved apart, said retaining ring (40) comprising a transverse stem (42) arranged in a plane (P2) that is inclined, including perpendicular, to the axial direction (A).
