Title:
高圧流体流コネクタのためのモニタリングシステム
Document Type and Number:
Japanese Patent JP4002610
Kind Code:
B2
Abstract:
A monitoring system for a fluid flow connector such as for oil or gas production flow is able to maintain the integrity of the seal at a junction between fluid conduits and generate a warning signal or activate a secondary seal in the event of main seal failure. The monitoring system of the invention is used with a hydraulic seal to which barrier fluid is supplied under pressure. The pressure of the barrier fluid is sensed at the seal and compared to the applied pressure. A drop in pressure indicates a leaking seal and a warning signal may be generated and/or a secondary seal brought into operation. The system is particularly useful when a plurality of junctions of conduits are present in a connector. Independent supplies of barrier fluid to the seals at each junction are provided so that identification of a leaking seal is accurate and timely.
