PURPOSE: A hydraulic pressure controlling valve for a fountain nozzle is provided to vary the height of water sprayed through a spraying nozzle using a valve body by adjusting the opened degree of a valve hole in the valve body. CONSTITUTION: A hydraulic pressure controlling valve is composed of a valve pipe(10), a valve body(20), and a controlling part(30). A supplying pipe is connected to the lower side of the valve pipe. A valve hole(15) is formed at the center part of the valve pipe. The valve hole has a tapered side. The valve body is screw-combined with the upper side of the valve pipe. The combined depth of the valve body is controlled. A spraying nozzle(60) is combined with the upper side of the valve body. The controlling part is combined with the lower side of the valve body. The opened degree of the valve hole is controlled by moving the controlling part.
