Diaphragm seal e.g. pipe seal for measuring pressure of aggressive viscous media, has membrane that includes edge area that is extended from membrane bed to sealing area, so that seal is directly formed on membrane bed

摘要

The diaphragm seal (1) has a diaphragm seal housing (2) which is embedded with a recess membrane bed and a membrane (4) which are arranged opposite to each other. The membrane includes an edge area (5) that is extended from the membrane bed to the sealing area (6), so that a seal (7) is directly formed on the membrane bed. The edge area of the membrane is formed with a before-coined structure in the form of a groove-shaped recess for receiving a sealing ring.
