Process diaphragm seal |
摘要 |
A process diaphragm seal includes a diaphragm seal body having a seal body ring portion surrounding a cavity and a diaphragm having a diaphragm ring portion. The diaphragm ring portion includes a diaphragm ring outer portion that corresponds to a seal body ring outer portion of the seal body ring portion and a diaphragm ring inner portion that corresponds to a seal body ring inner portion of the seal body ring portion. A first weld of the diaphragm ring outer portion to the seal body ring outer portion forms a closed path around the seal body ring portion. A second weld of the diaphragm ring inner portion to the seal body ring inner portion forms a closed path around the cavity. Between the first and second welds a diaphragm ring back surface is in substantially continuous contact with the seal body ring portion.
