Fixed Cone Valve
Fixed Cone valve is a free discharge valve whose control of flow rate is very simple and easy regardless of the magnitude of the water head. The valve is used for extra water discharge at dams and reservoirs, flow control of downstream agricultural water, protection discharge of hydraulic turbine or distributing reservoir water. The streamline shape at discharge is distributed into a conical shape and the energy of the fluid gets very weak, and therefore there is no harm to any object in the way of discharged water. Additionally, if discharge in a distributed status is not appropriate, discharge can be performed in a parallel jet status by attaching a cylindric hood at the downstream of the body or inside the water. This means that it is classified and used as an in-air discharge type and an in-water discharge type.
SPECIFICATION (STANDARD)
1.Size
· Nominal dia – 200 ~ 3000mm
· Pressure – 2.94Mpa (30kg/㎠)
· Major material
Body : SS400, SM450, STS304
Gate : SS400, SM400, STS304
Spindle : SUS403
Seat : RUBBER + SUS304
※Installed on a round cross section and downstream of the pipe mainly for high dam discharge, and the flow
is controlled by the movement of the gate after installing a 90˚ cone in the center. The actuating force of the gate is very small and the transfer power to open and close the gate is almost constant during the entire stroke.
