The utility model discloses a pressure blasting type oil drainage device which comprises an oil drainage valve body, a through hole structure arranged on the side wall of the oil drainage valve body in a penetrating mode and an oil drainage component connected in the through hole structure in a screwed mode, the oil drainage component is provided with a blasting piece arranged at the bottom of a concave hole structure, and the blasting piece is located at the inner end of the oil drainage component. The isolation groove is formed in the inner end of the oil drainage component around the rupture disk, stress generated by interaction between the oil drainage valve body and the oil drainage component can be effectively prevented from being transmitted to the rupture disk through the isolation groove, the effect of resisting and blocking the stress is achieved, and therefore it can be guaranteed that the pressure of the rupture disk is stable, and the service life of the rupture disk is prolonged.
