A multistage dynamic water seal device capable of preventing condenser vacuum damage belongs to the technical field of water seal of water feed pumps. The water seal device comprises water seal devices, and is characterized in that the number of the water seal devices is an odd number of at least three, all the water seal devices are arranged in the same row, every two adjacent water seal devices form a group from the first-stage water seal device, the last-stage water seal devices are independent and not grouped, and the water seal devices are arranged in the same row from the first-stage water seal device to the second-stage water seal device. The tops of the two water seal devices in each group are communicated through a top end communication connecting pipe, the middles of the two adjacent water seal devices in the adjacent groups are communicated through a middle communication connecting pipe, a water inlet pipe with a flange is arranged on the side face of the first-stage water seal device, and a water
