動力式緊急解放継手の制御及び監視システム

Japanese Patent JP7084325

B2

The present invention relates to a pneumatically, high pressure gas powered emergency release coupling control and monitoring system (S) comprising a powered emergency released coupling (1) arranged in a fluid-supply line (32) for conveying hazardous fluids, said powered emergency released coupling (1) comprising a couple of coupling members (10, 11) provided with mating faces (10A, 11A) for sealing engagement of the coupling members (10, 11) and formation of a pressurizable chamber (12) between said coupling members (10, 11), said system (S) comprising an actuation line (7) connected at its one end to the pressurizable chamber (12) and at its other end to a source (C) of high pressure gaseous media (GH), preferably high pressure nitrogen gas, an first actuating device (4A, 4B) arranged in the actuation line (7), wherein said system (S) provides a gaseous media at a pilot pressure level to said pressurizable chamber (12) and to said actuation line (7) in a position downstream the first actuation device (4A, 4B) or via said pressurizable chamber (12) for detection of any leakage of gas in the control and monitoring system (S), said pilot pressure gaseous media preferably being 15 low pressure nitrogen gas. The invention further relates to a pneumatically, high pressure gas powered emergency release coupling (1) and a control and monitoring method for such a system (S).
