【発明の名称】差圧・測定変換器用の接続ユニットとしてのバルブアセンブリ
Document Type and Number:
Japanese Patent JP3399536
Kind Code:
B2
Abstract:
This valve device assembly, which serves as a connection unit for a differential pressure transducer and is protected against false operation, has a first and a second inlet-end connection for connection to a differential pressure source, a first and a second outlet-end connection for connection to the differential pressure transducer, a first and a second chamber each with a valvelike shutoff device disposed therein, a first passage connecting the first chamber with the first outlet-end connection, a second passage connecting the first chamber with the second outlet-end connection, a third passage connecting the second chamber with the second outlet-end connection, and a fourth passage connecting the second chamber with the first outlet-end connection. In first end positions, the shutoff devices close the inlet-end connections. After one of the shutoff devices has been lifted from its end position, the pressure applied to the associated inlet-end connection is simultaneously applied to the two outlet-end connections. In further end positions, the shutoff devices close the second and fourth passages.
