- The diffuser length should be long enough to ensure the main flow deceleration. 扩压段应具有一定的长度以保证主气流减速到一定程度。
- A butterfly isolation valve cannot be installed directly to the valve inlet flange, as the disc will contact the orifice plate. 蝶阀隔离阀不能够直接安装在阀门进口法兰上，因为其阀瓣将会接触到节流板。
- Analyzing three Key elements of unidirectional flow in main flow zone. 分析了主流区单向流三要素。
- Pneumatic rotary orifice plate and operation trolley are also available for the full piece cowskin spray coating. 喷整张牛皮配气动旋转孔板及操作台车。
- Fluid resistance drop of Johnson screen is apparently lower than the one of wire-cloth and orifice plate within some certain range of pore space. 在一定的孔隙范围内,约翰逊网的流体阻力降明显小于编织网和孔板结构的阻力降。
- Sonic Nozzles for gases, Venturis, ASME Flow Nozzles and Orifice Plates or liquids will meet nearly all application requirements. 音速喷嘴，用于气体管，ASME流量嘴和孔板，或者液体，满足几乎所有应用需求。
