Zusammenfassung:The utility model discloses a drain valve of a surface air cooler, and relates to the technical field of surface air cooler devices. The utility model aims to solve the problems that when the drain valve is used for a long time, water leakage is easy to occur at the joint of the drain valve and a surface air cooler, and the existing drain valve needs to be installed by multiple persons and is time-consuming and labor-consuming. According to the drain valve of the surface air cooler, a sealing assembly in the drain valve comprises an annular driving piston, an annular sealing piston and an annular baffle. According to the drain valve of the surface air cooler, liquid is squeezed through the annular driving piston, the annular sealing piston is squeezed into the surface air cooler connecting flange, the piston is promoted to be meshed with the flange only through the liquid squeezing piston in the whole process, it is guaranteed that no gap exists between the drain valve and the surface air cooler, and the wate
