The invention relates to a reversing valve welding nitrogen charging monitoring device, a monitoring control method and equipment, and belongs to the technical field of nitrogen charging welding. The reversing valve welding nitrogen charging monitoring device is provided with nitrogen charging loops, a control assembly and a display assembly, wherein each nitrogen charging loop is provided with a time relay and a nitrogen charging switch which are connected in series; and according to the nitrogen charging state in each nitrogen charging loop, the display assembly is triggered to display in different display states. The time relays are arranged to control the nitrogen charging time, the nitrogen charging switches are matched to control starting and stopping of nitrogen charging, and then the display assembly monitors the nitrogen charging state in different display states, so that the problem that a sliding block is burnt due to a direct nitrogen charging mode is solved, the manual nitrogen charging time is s
