ⅳ内文丘里管（图6）内文丘里管如图6所示，从流体力学角度来看，它的节流件很类似，都只是一个后锥角很大的锥体，没有像文丘里管让流体动能转换为位能的扩张段。严格的来说不宜命名内文丘里管，而上述的槽道、梭式节流装置均有类似的扩张段，所以压损会比内锥、内文丘里管小。但是内文丘里管改善了内锥的支撑结构，消除了内锥节流装置的安全隐患，还是应充分肯定。

新型节流装置的技术性能*9（1）科学试验是评估技术性能的唯一手段近年来，面临工程中提出的一些新课题，我国流量业界比较活跃，引进或开发了不少新型节流装置，在推广应用中必然会面临一些问题，血的教训说明必须慎言缓行，切忌高歌猛进。怎样评估新型节流装置的技术性能？不是引用国外公司、文献的数据，或故弄玄虚的“理论”，唯一可行的只有科学试验。在这个过程中将积累成千上万的数据，并对这些数据认真整理，去伪存真。必要时对有疑惑的数据还应重新测试予以核实、印证。在此基础上归纳、整理、总结、为标准。这样的标准才有实用、推广价值，使生产厂家有数可依，使用者有据可查。
