- Perforated plate is taken as an important throttling component to regulate pressure in a pressure reducing valve or a high pressure vessel etc., based on its special structural characteristics. To regulate pressure to a target value, a self-designed multi-stage high pressure reducing valve (MSHPRV) is proposed. It has such advantages as avoiding noise and vibration. In this paper, flow fields analysis on perforated plate in MSHPRV is conducted from three aspects based on a validated numerical model. Firstly, different stages of perforated plate are investigated to figure out the impact of stage on flow fields. Secondly, different apertures of perforated plate are studied to find its impact on flow fields. Finally, different pressure ratios are discussed, in that pressure ratio plays an important role in flow field distribution. This work can benefit the further research work on perforated plate flow investigation and multi-stage design of pressure reducing devices and so forth.
