| description | A diaphragm valve can properly mount a peripheral portion of a diaphragm over the entire periphery and reliably establish a seal between the peripheral edge portion on a liquid side of the diaphragm and a diaphragm mounting seat for preventing leakage of a liquid. The diaphragm valve includes an annular base (
27
) provided to project from a seat surface of said mounting seat (
12
) for a predetermined height and connected with a bracket mounting flange (
16
) on the side of said valve operating portion by bolts (
17
). A diaphragm retaining portion (
30
) is formed integrally with said flange (
16
) for compressing the peripheral edge portion of said diaphragm with a constant pressure so that said flange (
16
) and said base (
27
) are connected by said bolts (
17
) in the condition where said diaphragm (
14
) is compressed onto said base (
12
) with said constant pressure by said diaphragm retaining portion (
30
). |
