FLUID CONTROL VALVE SYSTEM AND METHODS |
摘要 |
A diaphragm-type control valve having a diaphragm and a valve body is pro vided preferably for use in the separation of and fluid control between a fl uid source and a pressurized gas volume. The diaphragm element and a port in the body together form an intermediate chamber that eliminates the need for a check- valve downstream of the valve. In one preferred embodiment, an inn er surface of the valve body defines a chamber having an inlet and an outlet in communication with the chamber, and an elongated seat member defining a groove in communication with the port. A diaphragm member having upper and l ower surfaces is disposed within the chamber. The lower surface preferably i ncludes a pair of spaced apart elongated members defining a channel therebet ween. The diaphragm member engages the seat member placing the channel in co mmunication with the groove to define an air seat in communication with the port. |
