Study on Internal Parameters of Cage-Type Trim of Multi-Stage Depressurization Steam Trap

Abstract:

Aiming at the lack of research for key parameters of the cage-type trim of sleeve-type steam trap, the numerical simulation calculation was carried out for the cavitation flow in valve, the influences of orifice types, orifice diameter, guide sleeve types on cavitation were researched. The distribution of pressure, velocity and vapor volume fraction on flow field were got for different sleeve parameters. The results show that using multi-stage sleeve, and decreasing the orifice diameter properly can suppress the occurrence and development of cavitation, and the double orifices structure sleeve is more favorable to anti-cavitation, the gap sleeve is superior to the guide sleeve. It can provide certain references for the research of anti-cavitation and multi-stage depressurization valves.
