Hose or pipeline fracture protecting valve - has closure piston with adjustable by=pass responding to pressure loss on one side

摘要

The fracture protection valve for hose or tube responds to a very low pressure difference. The valve cone has a wide opening distance and it is not affected by external shock. The valve reopens automatically when the pressure is balanced once again. A bypass flow channel (5) is arranged across the valve closing piston (9). The flow cross section of this bypass channel (5) can be adjusted externally by an adjusting screw (3). The valve body (2) is placed into the pipeline section or pressure regulator and the bypass flow channel is a (6) through the connector (13) to the inlet end (18).
