Claims

[Scope of utility model registration request]

In a once-through water turbine in which a runner is rotatably supported in a casing, and water from the rotating runner is discharged into a water discharge garden through a water discharge pipe hanging down from the casing, water is discharged through a communication hole formed in the peripheral wall of the water discharge pipe above the water discharge garden. An air passage is provided for supplying air from the garden into the water turbine chamber directly below the inlet pipe connection part of the casing, and a through hole is formed in the air passage wall outside the water discharge pipe opposite to the communication hole, and a through hole is formed on the periphery of the through hole. An air introduction valve having a valve body that can be reciprocated along the center line of the through hole to move toward and away from the valve seat provided at the periphery of the communication hole and can be stored in the through hole is detachably attached to the provided mounting seat. A once-through water turbine characterized by the fact that it is equipped with a water wheel.
