Exhaust optimizing method for primary circuit of million-kilowatt-level nuclear power station

The invention relates to an exhaust optimizing method for a primary circuit of a million-kilowatt-level nuclear power station. The primary circuit of the nuclear power station comprises a reactor pressure vessel, a pressure stabilizer, a plurality of steam generators and a plurality of main pumps sequentially communicating by a main pipeline, and the plurality of steam generators correspond to theplurality of main pumps one by one. The method comprises the steps: carrying out water filling and exhausting on a circuit formed by communicating the reactor pressure vessel, the pressure stabilizerand the steam generators; and sequentially joggling the plurality of main pumps, and reducing the pressure to exhaust after completing the joggling of the plurality of main pumps so as to transfer gases in inverted U-shaped pipes of the plurality of steam generators to the reactor pressure vessel and then exhaust the gases in a water filling and exhausting way. By using the exhaust optimizing method for the primary circuit of the million-kilowatt-level nuclear power station, the exhaust time of the primary circuit of the nuclear power station is greatly shortened, and the wear and damage risks of the main pumps are greatly reduced.

Exhaust valve plate for compressor, exhaust valve module and compressor

The invention discloses an exhaust valve plate for a compressor, an exhaust valve module and a compressor. The exhaust valve plate for the compressor is substantially strip-shaped with a length as S; S is smaller than 25 mm and bigger than 15 mm; at least one part of the exhaust valve plate is bent to one side of an exhaust valve port so as to form a height difference h1 between one end and the other end of the exhaust valve plate; and h1 is smaller than 0.5 mm and bigger than 0.03 mm. According to the exhaust valve plate for the compressor, one part of the exhaust valve plate is bent to one side of the exhaust valve port so as to warp the end part; the warping height of the end part of the exhaust valve plate is controlled to form lower pressure between the exhaust valve plate and the exhaust valve port; meanwhile, the compensation effect on the machining error of the exhaust valve port and the like can be achieved; the exhaust valve plate can be tightly bonded on the exhaust valve port to reduce the leakage; and the warping structure of one end of the exhaust valve plate can enable the exhaust valve plate to obtain higher resilience force, so that the exhaust time is shortened, and the exhaust efficiency is improved.
