A water seal tank (5) is connected with a water pressure difference tank (7); an outlet of the water pressure difference tank (7) is provided with an overflow water tank (8); when the pressure of the gas medium exceeds a preset value, water in the water pressure difference tank (7) overflows to the overflow water tank (8), and the water pressure difference tank (7) is communicated with the atmosphere, so that the inflammable gas can be released; through adjusting the water pressure difference tank (7) and a separating board (12) as well as the height of the water level inside the water pressure difference tank (7), the release pressure and the working pressure can be regulated and set conveniently. The overflow water tank (8) is connected with the water pressure difference tank (7) through a water return pipeline (9), a gate valve (10) and a one-way valve (11); when the gas medium regains the normal pressure, water in the overflow water tank (8) flows back to the water pressure difference tank (7), and the relief valve automatically resets and stops releasing. The wet-type relief valve provided by the utility model has the advantages of automatic closing and resetting, convenience in regulating the releasing pressure, accuracy in setting the open/close pressure, and low releasing pressure of the valve.
