DIAPHRAGM VALVE WITHOUT A SUPPORTING RING AND WITHOUT A SUPPORTING PLATE

A diaphragm valve (DV), includes: an elastomer-diaphragm (ED) in/on a valve-housing via a radially-outer-edge-bead and interacts with a DV-seat (DVS); a first-control-chamber (CC), delimited by a first-surface, facing away from the DVS, of the ED and loadable and relieved of load by a pressure-mediu...

Beschreibung
Zusammenfassung:	A diaphragm valve (DV), includes: an elastomer-diaphragm (ED) in/on a valve-housing via a radially-outer-edge-bead and interacts with a DV-seat (DVS); a first-control-chamber (CC), delimited by a first-surface, facing away from the DVS, of the ED and loadable and relieved of load by a pressure-medium (PM), and when the first-CC is loaded, the ED is pushed against the DVS; a second-CC, delimited by a second-surface, facing away from the first-surface, of the ED and loadable and relieved of load and surrounds the DVS, and, when the second-CC is loaded by PM, the ED lifts off from the DVS and the second-CC is connected to a PM-flow-channel (FC), on which the DVS is formed at an end-side; and the PM-FC, DVS, ED are coaxial as to an axial-direction, and the smallest thickness of the ED's central-region, as to a radial-direction perpendicular to the axial-direction, is at least 30% of the PM-FC's inner-diameter.
