초록 ▼

A valve having a disposable portion, which comes into contact with the fluid being controlled by the valve. The disposable portion has a valving chamber and a flexible membrane, which can seal off a mouth that is located on a protrusion in the chamber. The disposable portion is held by a fixture which uses a control gas or a mechanical actuator to apply pressure to the flexible membrane. The disposable portion may also have a pressure conduction chamber, which may be used to measure the flow rate of liquid through the disposable portion.

대표청구항 ▼

A system for providing a valve in a line that delivers liquid, such that the portion of the valve that comes into contact with the liquid in the line may be easily disposable, the system comprising: a housing; a first flexible membrane disposed on the housing, the first flexible membrane having an internal side facing the housing and an external side facing away from the housing, the housing and the first flexible membrane defining a valving chamber; a liquid path passing through the housing from a first port through the valving chamber to a second port so as to provide liquid communication between the valving chamber and the line, the path entering the valving chamber at first and second mouths, wherein at least one of said mouths inside the valving chamber protrudes from one side of the housing towards the membrane; a fixture for holding the housing, such that the housing may be easily disengaged from the fixture; first pressure means, disposed in the fixture, for alternately (i) providing pressure to the external side of the first flexible membrane so as to force the first flexible membrane against the protruding mouth and (ii) relieving pressure on the external side of the first flexible membrane so as to permit relatively unrestricted flow through the liquid path through the valving chamber, wherein the first pressure means includes a mechanical actuator located in the fixture adjacent to the first flexible membrane; a second flexible membrane disposed on the housing, the second flexible membrane having an internal side facing the housing and an external side facing away from the housing, the housing and the second flexible membrane defining a pressure conduction chamber disposed in the liquid path, and second pressure means, disposed in the fixture, for alternately (i) providing pressure to the external side of the second flexible membrane in the region of the pressure conduction chamber and (ii) relieving pressure on the external side of the second flexible membrane in the region of the pressure conduction chamber.
