Steam drum water level condensation ball water injection device

The utility model relates to a steam drum water level condensation ball water injection device. At present, water in a condensation ball needs to be drained when a steam drum water level transmitter needs to be checked and freeze-proof in winter, so that the pressure difference generated on the positive pressure side and the negative pressure side of the transmitter cannot be normally reflected due to the fact that no condensate water exists in the condensation ball of the steam drum when a unit is started every time. The steam pocket water level condensation ball water injection device comprises a steam pocket (1), the positive pressure side of the steam pocket is connected with a condensation ball (2) through a pipeline, the condensation ball is connected with a water supply pipe (3), the water supply pipe is connected with a water injection pipe (5) through a connector (4), the water injection pipe is connected with a direct-current electric pump (6), the direct-current electric pump is connected with a wa
