The fixed cone valve is mainly composed of valve body, nozzle, sleeve gate, rocker arm, inlet and outlet pipe, drive shaft and floating valve seat. This valve can be used as a free discharge valve at the end of the turbine generator set. What are the classifications of the structure of the fixed cone valve? The structure classification of the fixed cone valve is as follows: In-pipe type: Installed in the pipeline for flow regulation, pressure reduction or pressure relief purposes. According to site conditions, manual turbine, electric, hydraulic automatic control, etc. can be used. Discharge type: Discharge type fixed cone valves are often installed in turbine generators, reservoir dam bottoms, etc. for free discharge or reservoir flood discharge. According to site conditions, manual turbine, electric hydraulic automatic control, etc. can be used. The fixed cone valve drives the rocker arm to rotate through manual turbine, electric or hydraulic, and then drives the sleeve through the slider
