Abstract:
To allow high speed liquid supply by a simple configuration.SOLUTION: A water stop mechanism 1 closes a valve 20 between a supply side and a discharge side by interlocking with rise of a float 16 in accordance with rise of a water level W1. The water stop mechanism 1 comprises a second valve member 14 and a pressure chamber 81. The second valve member 14 constitutes the valve 20. The second valve member 14 operates so that the valve 20 is closed in accordance with the rise of the float 16 and operates so that the valve 20 is opened in accordance with fall of the float 16. The pressure chamber 81 is formed on an upstream side from the second valve member 14 in a direction in which water flows, and water on the supply side is guided to it when an aperture of the valve 20 decreases. The second valve member 14 is moved in a valve opening direction by pressure of the water guided to the pressure chamber 81.SELECTED DRAWING: Figure 3
