Title:
WATER PRESSURE CONTROLLER
Document Type and Number:
Japanese Patent JPS61253518
Kind Code:
A
Abstract:
PURPOSE:To perform easily the discharge of a fixed amount of water, the closure of a valve for an optional period, the automatic holding of water at fixed level, etc., by opening and closing a pressure reducing valve in response to the up-down movements of an up-down controllable float and also adding an independent open/close controller for the reducing valve. CONSTITUTION:An independent open/close controller 28 is kept in a free state and the pressure water is supplied through a water pipe 6. Thus the water is decompressed by a pressure reducing valve 14 and supplied. Then the water rises up to a fixed level under the atmospheric pressure and at the same time a float 17 rises up. Then upper and lower levers 19 and 20 work to make the valve bodies approximate or touch close to their valve seats. Thus the supply of water is stopped from the valve 14 and the rise of the water level is also stopped. When the water level is lowered down to a prescribed position, the fall of the float 17 is controlled to close the valve 14 at a prescribed level and to stop the supply of water. While the controller 28 is operated to keep the valve 14 at a fixed opening amount and also to close the valve 14 at an optional time point in case a fixed amount of water is discharged.
