Summary: | The utility model discloses an anti-misconnection device for a hydraulic control pipeline of a blowout preventer. The device comprises a hydraulic pipeline and a magnetic sleeve head with magnetism of an S pole and an N pole, the two magnetic sleeves are respectively an S-pole magnetic sleeve and an N-pole magnetic sleeve; wherein S and N represent the magnetic field polarity of the end, facing a pipe opening, of the magnetic sleeve head, magnetic sleeves with the same polarity are installed at the two ends of the hydraulic pipeline, and an S-pole magnetic sleeve, a remote controller well closing oil outlet and an oil port of a blowout preventer well closing oil cavity are installed at the oil port of the remote controller well opening oil outlet and the oil port of the blowout preventer well opening oil cavity. The device can automatically identify whether the blowout preventer hydraulic pipeline is correctly installed or not, prevents the hydraulic pipeline from being connected mistakenly, and is simple in |
