This piping components and optical signal transmission function with fluid piping

摘要

PROBLEM TO BE SOLVED: To transmit various kinds of fluids, propagate pressure, and transmit a light signal with the same pipe by arranging light signal connectors for one or two-way transmission on both end parts of a pipe body in which a port for a fluid is arranged. ;SOLUTION: In a fluid pipe, a light/fluid hybrid connector 1 for transmitting a light signal is disposed on a fluid inlet side end part of a leading pipe 1-2 with a flare. When a connector main body 1-1 of the light/fluid hybrid connector 1 is connected to a joint part 3 for feeding a fluid, for example, transmissions of the fluid and the light signal are simultaneously performed. In this time, the fluid is passed flow paths 1-1a, 1-1b of the connector main body 1-1, it flows a leading pipe 1-2. On the other hand, the light signal is propagated from an optical fiber 1-6 connected to the light/fluid hybrid connector 1 to a receiving side through a sleeve 1-4 while reflecting a pipe inner circumferential surface in the same leading pipe 1-2 from the flow path 1-1a of the connector main body 1-1.;COPYRIGHT: (C)2001,JPO
