Title: Check valve for liquid chromatography systems - with ring-supported seal of deformable polymer having significant recovery characteristics
Inventor: FINN LAWRENCE JAMES
IPC: F04B53/10
Filed: 1976-02-27
Abstract: Check valve, esp. for chromatography systems, has a housing, a flow path between an inlet opening and an outlet opening, a check valve unit, a pressure-operated device for moving the check valve unit between a first position, in which the flow path is open, and a second position, in which the flow path is open, and a seal placed in the housing and consisting of a polymer material having significant recovery characteristics, so that the seal repeatedly returns from a temporary shape to a permanent fixed, shape. A ring is provided for holding the seal in the correct position, and preventing a significant change in the shape of the seal in the direction of the outlet opening when an extrusion pressure is applied to the seal. The extrusion pressure is exercised by the check valve unit so that a part of the seal is extruded from the permanent shape to the temporary shape extending between the unit and other parts of the valve in the direction of the inlet opening, thus forming a liquid-tight seal between the inlet opening and the outlet opening. The displacement into the temporary shape effected by the unit is restricted so that the recovery characteristics of the polymer are not exceeded, the seal returning to its permanent shape when the unit is situated in its first position. The seal is pref. made of PTFE. Valve operates rapidly and exactly in cooperation with the pump of a liquid chromatography system, and does not effect the reliability of the pump during long operation periods. It resists contamination by residues obtd. from the pump, without requiring the provision of a filter. No dead spaces exist at the inlet and outlet openings.
