Steam balancing regulating system of composite type condenser

A steam balancing regulating system of a composite type condenser comprises a vacuum pump, an evaporative type condenser and a direct air-cooling condenser. The vacuumizing effect of the direct air-cooling condenser and the vacuumizing effect of the evaporative type condenser are regulated through an air-cooling vacuumizing regulating valve and an evaporative type condenser vacuumizing regulating valve, and therefore the pressure at the vacuumizing opening of the evaporative type condenser and the pressure at the vacuumizing opening of the direct air-cooling condenser can be made the same, the problem that when non-condensable gas is accumulated inside a certain device of the composite condenser, no steam enters the composite condenser or a small amount of steam enters the composite condenser is effectively solved, and the efficient, energy-saving and water-saving comprehensive performance of the composite condenser is given into full play.
