China Pnumatic Hydraulic Cast Steel Pn10 Pn16 Pn25 Free Discharge Fixed Cone Valve in Dams and Reservoirs, Find details about China Hollow Jet Valve, Fixed Cone Valve from Pnumatic Hydraulic Cast Steel Pn10 Pn16 Pn25 Free Discharge Fixed Cone Valve in Dams and Reservoirs
AEA Fixed cone valves also named hollow Jet valves are mainly used as discharge valve in turbine bypass valves , reservoir or other discharge purpose and can regulate flow also.
These valves are used to discharge water at high pressure from reservoirs or full pipes into atmosphere. Some designed valves can also work submerged in the water. A hood can be incorporated at the end of the valve.
With features: simple cone valve structure , low head loss , low flow resistance coefficient , various operation mode, advanced anti-cavitation design and long product life.

The Fixed Cone Valve is mainly composed of a nozzle, a fixed cone sleeve, gate, seat, dome and driving machine etc.. Nozzle with fixed cone by radial blades strut and link, between the nozzle and vertebral retained a walled open section of the pipe, sleeve brake installed on the outside of the nozzle and through the axial movement of the sleeve gate change without casing wall open segment length, to adjust the valve opening degree. The valve outlet can be set according to the actual work dome, the dome may constrain the valve outlet water flow. The valve is driven by regulation. The fixed cone valve and discharge type two in charge of medium structure, medium tube installed in the pipeline from central to stop, decompression, traffic control and other functions. Tubes are generally installed in the flow guide cover, to avoid the valve back end pipeline by cavitation damage. The discharge type is installed at the end of the pipe, which has the function of pressure relief, pressure regulation and water level control.
