Value device assembly as a connection unit for differential pressure transducers
First Claim
1. A valve device assembly serving as a connection unit for a differential pressure transducer, comprising:
- a first inlet-end connection and a second inlet-end connection for connection to a differential pressure source;
a first outlet-end connection and a second outlet-end connection for connection to the differential pressure transducer;
a first chamber with a valvelike first shutoff device disposed therein;
a second chamber with a valvelike second 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, whereinthe first shutoff device closes the first inlet-end connection in a first end position, and the second shutoff device closes the second inlet-end connection in a second end position;
after the first or second cutoff device has been lifted from the first or second end position, respectively, the pressure applied to the associated inlet-end connection is simultaneously applied to the two outlet-end connections; and
the first shutoff device closes the second passage in a third end position, and the second shutoff device closes the fourth passage in a fourth end position.

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.
