葛洲坝工程船闸廊道阀门原型观测研究

Prototype Observation and Investigation of the Culvert Valve of the Shiplock of Gezhouba Project

本文阐述葛洲坝3号船闸输水廊道反向弧形阀门的原型观测,发现在阀门面板上产生的蚀损分布与被水流激发的振动型态相当吻合,建立了蚀损不仅与空穴水流有关而且与阀门振动特性有关的概念。

Through the prototype observation on the reversed arc valve of the filling culvert of No. 3 shiplock at Gezhouba Project, it was found that the distribution of erosion damage occurred on the surface of the valve is fairly in accord with its vibration models induced by the flow.This paper presents the concept that the erosion damage is not only related to the cavitation flow,but also to the vibration characteristic of the valve.
