介绍了ＨＴＶ船型浮阀塔板在荆门石油化工总厂北蒸馏装置常压塔及延迟焦化装置分馏塔上的应用情况。重点叙述了两塔的工艺计算、生产操作、装置标定、设备检修等，并通过与Ｆ１型国浮间比较，说明ＨＴＶ船型浮问具有操作弹性大、适应能力强、分馏效率高、易制造、安装检修方便等优点，适于在大型分馏塔以及分馏塔扩大处理量时采用。
The application of HTV ship valve trays in the atmospheric tower of northern distillation unit and the fractional distillation tower of delayed coking unit in Jingmen Petrochemical Complex was introduced. The article mainly elaborates the process calculation, production operation, device calibration and equipment overhaul of the two towers. The comparison between the floating floats and F1 floats shows that the HTV ship floats have great flexibility of operation, strong adaptability, high fractional distillation efficiency, easy manufacture, Installation and maintenance convenience, etc., suitable for large fractionation tower and fractionation tower to expand the amount used.
