摘　　要：牛栏江—滇池补水工程水库排空超大直径锥形阀工作水头超过160m,喷管直径达2800mm,是目前国内水利工程应用直径最大,工作水头最高的锥形阀。本文介绍了该锥形阀的选型设计、模型试验、现场试验,并对锥形排放阀的排放系数、空蚀、振动、补气等问题进行了探讨。The cone valve applied on Niulanjiang-Dianchi water-replenishment project is the maximum-diameter and highest-head cone valve in domestic hydraulic projects, with diameter exceeding 2800mm and working head exceeding 160m. The type selection, design, model test and field test of this valve are presented in this paper. The discharge coefficient, cavitation resistance, vibration stability and air replenishment of this valve are discussed.
