Research cone valve stilling basin has important academic significance

Diversion tunnel and spillway tunnel often used aqueduct, so there is the problem of energy dissipation and pipeline control flow within the pipe exports. The traditional way to pick flow dissipation and often more difficult to overcome the problems caused atomization, cavitation damage, slope erosion and so on. Set in a tapered pipe outlet flow control valve only solve the problem of energy dissipation have a good effect, the application becomes a cone valve research attention more and more experts and scholars, research focus, cone valve stilling has important academic  Instrument valve manifolds  and practical value, and can produce some economic value. Research work of this paper is Kongtong water reservoir reinforcement project on the cone valve outlet hole stilling basin model expanded, cone valve on the hydraulic  High pressure ball valve  of stilling pool of various conditions were studied. Experimental studies using numerical simulation and theoretical analysis method of combining some variation of the hydraulic characteristics of the series of changes occurring energy dissipator various kinds of body parameters generated by research and discussion, and shape optimization.
