The invention provides an overpressure relief device with a controllable opening mode. The overpressure relief device has an automatic opening mode, a manual opening mode and a remote control openingmode. The device can realize an overpressure automatic release function, namely when the pressure in a fuel depot rises to reach a set threshold value, a cover can be automatically opened to dischargehigh-pressure gas to a safety channel, and meanwhile, manual and remote control opening functions are achieved, manual and remote control opening can be conducted no matter whether the pressure in the fuel depot reaches a set threshold value or not, and toxic and harmful gas in the fuel depot is discharged to the safety channel outside the fuel depot. The device has the advantages of being reliable in locking, rapid in opening, controllable in opening modes, simple in structure and convenient to maintain. 本发明提供了一种开启模式可控的超压泄放装置，具有自动、手动和遥控开启模式的超压泄放装置。本发明提供的装置可实现超压自动泄放功能，即当燃料库内压力升高达到设定阈值后，可自动开盖将高压气体排出至安全通道；同时还具有手动及远程遥控开启
