dam discharge valve KE-DVG Series

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 entireValve Temperature Measurement for Reciprocatingobserved that on 12 November the discharge valve cover skin temperatures and the discharge temperature lie close to each other.Together,these observations indicate effective sealing by the piston rings and cylinder valves.On 13 November a leak develops in one of the crank end discharge valves.Those Dam Valves and the Great Job They DoDuri Working on valves or piping within a dam environment sometimes calls for getting into tight spots.ng the early part of the 20th century,standard valve types such as gate and globe valves were given this flow control job.But the effects of cavitation destroyed them at an alarming rate.

Sluice gate flow metering is often used to measure flow rate in open channels.Sluice gates are also often used to modulate flow.The sluice gate flow rate measurement is based on the Bernoulli Equation and can be expressed as:.1/2 v 1 2 + g h 1 = 1/2 v 2 2 + g h 2 (1).where.h = elevation height (m). = density (kg/m 3).v = flow velocity (m/s)Sleeve Valve Energy Dissipaters - Valve Manufacturer36 Model 711 Inline Sleeve Valve Reservoir Discharge Pratt dam discharge valve KEsleeve valves are used to control flow and dissipate excess energy from a reservoir outlet.Commonly used in areas with a high pressure drop,the sleeve valve can discharge to the atmosphere,or to a

results for this questionWhere should drain control valves be placed?Where should drain control valves be placed?Drain control valves and gates should always be placed upstream of the centerline of the dam.This allows the drain conduit to remain depressurized except during use,therefore reducing the likelihood of seepage through the conduit joints and saturation of the surrounding earth fill.Reference damsafety/dam-owners/lake-drains results for this questionFeedbackfixed cone discharge valve KE-FCV Series

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.
