The utility model relates to a plugging equipment technical field is a relief valve mending -leakage plugging device, including the equipment jar body, relief valve with glue the mucigel, have the leak source on the equipment jar body, leak source department be equipped with can with leak source intercommunication and can be with the relief valve of its shutoff, the fixed terminal surface of relief valve and the external side profile of surface phase -match of the equipment jar that corresponds, the fixed terminal surface and the external side of equipment jar of relief valve are in the same place through gluing mucigel fixed mounting, the middle part of gluing the mucigel is equipped with the passageway that runs through that can feed through leak source and relief valve. It is sealed that the shutoff can be carried out to the leak source of the equipment jar body to this practicality, easy operation, and labour saving and time saving, simple and convenient high -efficient, it carry out corresponding processing through opening the relief valve can directly personally experience sth. Part of the body to the equipment jar that has pressure, can satisfy the urgent demand of handlingof accident, and is in the same place the relief valve with equipment tank connection through gluing the mucigel, can shorten the time that the solidification of mending -leakage glue needs, and is still applicable in various rules and anomalous leak source defect, has good adaptability.
