Abstract
Four kinds of cavitations suppression schemes on the basis of cavitations theory of control valve were designed in this paper. The fluid dynamic characteristics parameters under the above schemes was obtained by using RNG k-ε turbulence model respectively, which is composed with the velocity vector of internal fluid, pressure and cavitations distribution contours of numerical simulation. The results show that the design of straight-through porous structure has a lot of advantages compared with other structures in terms of its good fluid dynamic characteristics that fluid flow is uniformly in the valve cartridge, the loss of pressure is lower, the impaction in expansion cartridge is smaller and impact noise of it can be reduced. Therefore, the straight-through porous structure could suppress the initiation and development of the cavitations.
