摘　　要：S管阀是一种广泛用于混凝土喷射机的关键部件,它的性能直接影响混凝土喷射机这类混凝土机械的使用性能。为减少混凝土在混凝土喷射机S管阀中的流动阻力和阻塞管道,利用量纲分析理论,建立了适用于计算液体力学Fluent软件的S管阀仿真数学模型,在给定条件下对所建立的模型进行了多次仿真,得到了S管阀各段长度的最佳比例关系,并确定S管阀最优的抛物线方程。S-type tube valve is one of the key components widely used in concrete machinery. Its property can di- rectly affect the performance of this kind of machines such as spraying concrete machine. By using the theory of di- mensional analysis, its mathematical simulation model which is suitable for computational fluid dynamics software Fluent was made in order to reduce flow resistance through it in concrete spraying machines and to prevent clog- ging. The optimum proportion of each level length of it was obtained by numerical simulation under given condi- tions. The optimal parabola equations of it were also built in this paper.
