摘要： A safety system for a fluid conduit includes an elongated flexible conduit having a first end and a second end and a central opening running therethrough and capable of transporting a first fluid under pressure. A first valve is located near the first end of the conduit and a second valve is located near the second end of the conduit. Each of the valves is moveable between a closed position and an open position so as to control the flow of the first fluid through the conduit. The central opening of the conduit is surrounded by a conduit wall which extends substantially the entire length of the conduit. A plurality of enclosed channels are located within the conduit wall and extend at least a substantial length of the conduit. A second fluid under pressure is contained in the channels and a sensor is provided for monitoring the pressure of the second fluid within the channels. One or both of the valves are operatively associated with the second fluid and close when the monitored pressure falls below a predetermined level.
