A parametric study on cavitation flow through steam trap valves under high pressure difference
(2019) XII International Conference on Computational Heat, Mass and Momentum Transfer, ICCHMT 2019- Abstract
- Steam trap valves are mainly used in thermal power systems to pour out condensate water and keep steam inside. While flowing
through steam trap valves, the condensate water is easy to reach cavitation, which may cause serious damage to the piping
system. In this paper, in order to suppress cavitation inside steam trap valves, effects of valve body geometrical parameters
including orifice diameter, installation angle and the thickness of the cage are investigated by using a cavitation model. The
pressure, velocity and steam volume fraction distribution inside valves are analyzed and compared in different geometrical
parameters. The total vapor volumes are also predicted and compared. The results show that geometrical... (More) - Steam trap valves are mainly used in thermal power systems to pour out condensate water and keep steam inside. While flowing

suppress cavitation are found and verified. The work is of significance for the optimization design of steam trap valves. (Less)
