PROBLEM TO BE SOLVED: To provide the discharge regulator of a codensate pump which is used in a condensing and water-supplying device of a plant using commonly the minimum flow bypass line of high pressure condensate pump and nuclear reactor water-supplying pump and which protects the high pressure condensate pump through regulation of its/their rate of flow in case there is a difference in the Q-H characteristics between a plurality of high pressure condensate pumps. SOLUTION: The discharge regulator of a condensate pump is configured so that a plurality of high pressure condensate pumps 4a and 4b are in parallel connection for boosting the condensate for water heaters 5 and 8 and water- supplying pumps 6 and 7 of a nuclear power plant, wherein circulative pipings 25a and 25b in which circulation stopping valves 22a and 22b, circulation check valves 23a and 23b, and orifices 24a and 24b are interposed in series arrangement are connected between the discharge side and suction side of each high pressure condensate pump 4a/4b. |
