Abstract

The present invention provides an angle valve with embedded reducing valves, capable of preventing accidents due to an excessive pressure by discharging a fluid through a discharge connection unit while a pressure of the fluid is decreased by forming the reducing valves to be integrated with the discharge connection unit of the angle valve. In addition, the present invention provides an angle valve with embedded reducing valves, capable of reducing construction costs without additional installation of a separate reducing valve when installing the angle valve inside a fire hydrant box and preventing time consumed by installing the additional reducing valve and a water leakage. The angle valve includes: a body (3) wherein an intake connection unit (1) and a discharge connection unit (2) are formed to be curved; a disc (4) allowing and preventing a flow of the fluid inside the body (3); and a spindle (5) and a handle (6) adjusting the disc (4). The reducing valves (7) protruding inward from an inner circumference of the discharge connection unit (2) are integrally formed. The fluid received through the intake connection unit (1) passes through the discharge connection unit (2) via an internal space of the body (3). The fluid penetrated through the discharge connection unit (2) passes through the reducing valves (7) with a diameter smaller than a diameter of the discharge connection unit (2). The pressure of the fluid penetrated through the reducing valves (7) decreases while the fluid passes through the discharge connection unit (2) with a diameter larger than the diameters of the reducing valves and then the fluid is discharged.
