Claims

[Scope of utility model registration request]

A water turbine chamber, a water supply hole for supplying water to the water turbine chamber, and a drainage hole for discharging water from the water turbine chamber to the outside are provided in the case body, and a water turbine chamber is provided in the middle of the water supply hole. A water flow valve that can open and close the water supply hole is installed, and a water wheel that rotates according to the amount of water is installed in the flow path connecting the water supply hole and the drainage hole in the turbine chamber. A cam for opening and closing the water valve is connected via a reduction gear train, and when the cam is rotated, the water valve is opened, and when the cam is returned by the rotation of the water wheel, the water valve is closed. In the water flow control device, a pressure reducing passage that communicates the inlet of the water supply hole and the water turbine chamber is provided in the water flow valve body of the water flow valve, and a pressure reducing valve that can open and close the pressure reducing passage is disposed,
The pressure reducing valve includes a pressure reducing valve body that can open and close a pressure reducing passage by moving in the same direction as the opening and closing movement direction of the water flow valve body, and a pressure reducing spring that biases the pressure reducing valve body toward the water turbine chamber. A driven member is fixed to the pressure reducing valve body and is moved by the cam in the same direction as the opening/closing direction of the water valve body, and the driven member is engaged with the water valve body. The member is fixed, and after the driven member is moved by the cam to a certain extent against the pressure reducing spring from the fixed position of the engaging member, the engaging member engages with the water valve body and opens the water valve. A water flow control device characterized by being configured to:
