Research on the Basic Structure of High Pressure Large Ball Valve
The foundation structure of large inlet ball valves for hydropower stations with high pressure generally adopts the design that the base of the ball valve and the base plate of the ball valve can slide relative to each other.Under different friction coefficients,the influence of extrusion pressure due to temperature change on ball valve legs and concrete piers is calculated and analysed;different sliding sub-structures between ball valve base and ball valve foundation are compared and analysed.
