Abstract
A spray nozzle and a deaerator each include an external cylinder provided with a plurality of jetting outlets on an outer circumference portion thereof, an inner cylinder that is supported inside the external cylinder so as to be movable in an axial center direction and is provided with a plurality of first communication holes capable of communicating with the jetting outlets, and an open-close valve that includes a shaft coupled to the inner cylinder and a valve body provided at a distal end portion of the shaft and capable of opening and closing a distal opening of the external cylinder. The spray nozzle and the deaerator thus structured provide improved performance by preventing an increase in pressure loss occurring regardless of a jet flow amount.
