A bend pipe fixed cone valve is a valve with an inverted cone plug valve core structure, hence also known as a cone valve or energy dissipation valve. It is primarily used for bypass valves in hydraulic turbine generators, free discharge valves, and continuous flow control, and is also suitable for agricultural irrigation and similar applications.

Operating Principle

The bent pipe fixed conical valve adjusts flow by changing the distance between the movable valve sleeve and the fixed conical body. The annular space between the sleeve and the cone is used for discharge, and the sleeve is moved forward and backward along the flow direction by a screw drive to regulate the flow. When fully open, the flow coefficient can reach above 0.85.

Structural Features

The bent pipe type fixed conical valve features the following:

Excellent energy dissipation: Energy is dissipated through the friction of water and air, as well as the whirlpool formed upon entering the water, reducing impact on downstream pipelines or structures.

Flow Control: The conical design ensures a linear relationship between flow and valve core displacement, offering excellent regulating performance.

Simple structure, easy operation: The full valve's weight is supported by the root anchoring bolt, with good structural load conditions.

Application Scenario

Bend pipe fixed conical valves are widely used in the following scenarios:

Turbine-generator set: Used as a bypass valve or discharge valve for regulating and controlling flow.

‌Agricultural Irrigation: Featuring excellent energy dissipation and flow control capabilities, suitable for agricultural irrigation systems.‌
