After the connection and positioning of the male and female connectors are completed, oil starts to be supplied, in the process of the connection and positioning of the male and female connectors, the first valve core 130 and the second valve core 230 contact with each other and then move in opposite directions simultaneously under the mutual acting force, the spring forces of the first valve core spring 120 and the second valve core spring 220 which are overcome respectively open the first overflowing flow passage 101 and the second overflowing flow passage 201, oil flows out of the high-pressure manifold, then flows through the first bracket central flow passage 111 and the first bracket overflowing flow passage 112 to enter the first inner cavity 340, then flows through the first overflowing flow passage 101 to enter the second inner cavity 350 and the third inner cavity 360, then flows through the second overflowing flow passage 201 to enter the fourth inner cavity 370, and finally flows through the second bracket central flow passage 211 and the second bracket overflowing flow passage 212 to enter the supplied oil pipe.
It should be noted that, in the embodiment of the present invention, whether the positioning sliding sleeve 140 reaches the right limit or not can be determined through the indicating rod 170, when the positioning sliding sleeve 140 reaches the right limit position, the indicating rod 170 is flush with the end surface of the fixed sleeve 160, when the positioning sliding sleeve 140 reaches the left limit position, the length of the indicating rod 170 extending out of the end surface of the fixed sleeve 160 is determined, and the length dimension can be known through the reading of the graduated scale of the indicating rod 170.
When the shuttle tanker and the oil receiving platform need to be separated emergently in case of sudden working conditions, firstly, the oil receiving pump stops working, then an external hydraulic system injects high-pressure hydraulic oil into the first hydraulic oil flow passage 161, drives the positioning sliding sleeve 140 to move rightwards to a right limit position against spring force, and determines whether the positioning sliding sleeve 140 reaches the right limit through the indicating rod 170, at this time, the sliding sleeve positioning groove 141 leaves the positioning bead 180 to release the radial fixation of the positioning bead 180, at this time, an external power component drives the male connector 200 to be separated from the female connector body 100 quickly, in the process, the first valve core 130 and the second valve core 230 rapidly and automatically block the first overflowing flow passage 101 and the second overflowing flow passage 201 under the spring force action of the first valve core spring 120 and the second valve core spring 220, so that oil leakage is avoided, and the shuttle tanker is far away from the oil receiving platform.
The invention provides a shuttle tanker oil receiving port emergency separation device for shuttle tanker and oil receiving platform oil receiving operation, which can realize quick separation of the shuttle tanker and the oil receiving platform when an emergency or emergency situation occurs, reduce casualties and property loss and protect operation equipment; and the shuttle tanker and the oil receiving platform can be quickly and automatically closed after being separated, so that the environmental pollution and potential safety hazards caused by oil leakage are avoided. When the female connector and the male connector are quickly separated, the first valve core 130 and the second valve core 230 can respectively and quickly reset under the action of the spring force of the first valve core spring 120 and the second valve core spring 220 to quickly block the first overflowing flow passage 101 and the second overflowing flow passage 201, the first sealing ring 410 and the fourth sealing ring 440 can play a certain buffering role in the process, direct collision between the positioning shaft shoulders of the first valve core 130 and the female connector body 100 and between the positioning shaft shoulders of the second valve core 230 and the male connector body 200 is avoided, and the first valve core 130 and the second valve core 230 are prevented from being completely separated due to over-emergency stress, so that unnecessary trouble and loss are avoided when connection is restored. The invention improves the reliability and stability of the shuttle oil wheel in receiving oil on the oil receiving platform, can complete the oil receiving operation more conveniently and safely, can realize quick separation to ensure the safety of ships and workers in case of emergency or emergency, and provides reliable guarantee for the safe oil receiving.
